  In a third aspect based on the first aspect, the image correction means is configured to make the brightness or saturation of the newly updated image of the left-eye image and the right-eye image relative to the other. The image displayed on the display device is corrected by reducing the image to a minimum.

  According to a fourth aspect of the present invention, in any one of the first to third aspects, the image correction unit includes: a newly updated image for the left-eye image or a right-eye image; When there is a significant change, image change determination means for determining that the image has been updated to a new image is provided, and the image displayed on the display device is corrected based on the determination result.

  According to a fifth invention, in any one of the first to fourth inventions, the image correction unit is configured to newly update the left-eye image or the right-eye image, and to synthesize the image. An image change determination unit that determines that a new image has been updated when the other image greatly changes is provided, and an image to be displayed on the display device is corrected based on the determination result.

  According to a sixth aspect based on the fifth aspect, the image change determining means includes image level calculating means for calculating an image level of an image displayed on the display device. The magnitude of the change in the image displayed on the display device is determined.

  In the second aspect of the invention, the display device includes luminance control means for independently controlling luminances of the left-eye light source and the right-eye light source, and the image correction means is a left-eye image or a right-eye image. Is updated to a new image, the brightness setting of the brightness control means is changed.

  In addition, the image display device provided with a display area for variably displaying a plurality of identification information, and a variation display control means for controlling the variation display of the identification information (or effect control means for controlling the overall effect), This is a gaming machine that can perform a variable display game in which the identification information displayed on the image display device is variably displayed, and can generate a special game state that gives a specific game value in relation to the result mode of the variable display game.

  Further, the variable display control means (or the effect control means for controlling the overall effect) has an image correction means for darkening the image updated during the variable display game.

  The variable display control means (or the effect control means for controlling the overall effect) reads a preset display control procedure (sequence data) and displays an image, and the sequence data indicates image switching.

When the image changes, either the left-eye image or the right-eye image is updated to a new image, and the other image remains the old image, so the image observed with the left eye differs from the image observed with the right eye. By displaying the updated image so that it is relatively dark compared to the other image, the observer may delay recognition because the new image is relatively darker than the old image. On the other hand, since the old image is displayed relatively brighter than the new image, the observer quickly recognizes the old image, so even if the left and right images have different display contents, the observer feels uncomfortable. It can prevent giving.

  In the second invention, the brightness of the new image can be reduced by relatively reducing the luminance of one of the light source for the left eye and the light source for the right eye.

  In the third invention, the brightness of one image of the left-eye image and the right-eye image is relatively reduced, so that the brightness of the new image can be reduced.

  In addition, according to the fourth aspect of the present invention, when the updated image and the image before the update are largely changed, the newly updated image is displayed in a dark state, and the viewer can perform even if the left and right images have completely different display contents. This can prevent the user from feeling uncomfortable.

  In the fifth aspect of the invention, when the updated image and the other image combined with this image change significantly, it is determined that the image has been updated to a new image, and the image is corrected. Even if the display contents are completely different, it is possible to prevent the observer from feeling uncomfortable.

  Further, the sixth invention can determine that the image has changed greatly depending on the image level, and can prevent the viewer from feeling uncomfortable when the left and right images are completely different regardless of the type of the image.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is an explanatory diagram showing a configuration of an image display apparatus according to an embodiment of the present invention.

  The light source 1 includes a light emitting element 10, a polarizing filter 11, and a Fresnel lens 12. The light emitting element 10 is configured by using point light sources such as white light emitting diodes arranged side by side or linear light sources such as cold cathode tubes arranged horizontally. The polarizing filter 11 is set so that the light transmitted through the right region 11a and the left region 11b have different polarizations (for example, the light transmitted through the right region 11a and the left region 11b is shifted by 90 degrees). The Fresnel lens 12 has a lens surface having concentric irregularities on one side.

  The light emitted from the light emitting element 10 is transmitted only by the polarization filter 11 with a certain polarization. That is, of the light emitted from the light emitting element 10, the light passing through the right region 11a of the polarizing filter 11 and the light passing through the left region 11b are irradiated to the Fresnel lens 12 as differently polarized light. As will be described later, light that has passed through the right region 11a of the polarizing filter 11 reaches the left eye of the observer, and light that has passed through the left region 11b reaches the right eye of the viewer.

  In addition, even if it does not use a light emitting element and a polarizing filter, what is necessary is just to comprise so that light of a different polarization may be irradiated from a different position, for example, providing two light emitting elements which generate the light of a different polarization, You may comprise so that light may be irradiated to the Fresnel lens 12 from a different position.

  The light transmitted through the polarizing filter 11 is irradiated to the Fresnel lens 12. The Fresnel lens 12 is a convex lens, and the Fresnel lens 12 refracts the optical path of light emitted so as to diffuse from the light emitting element 10 to be substantially parallel, transmits the fine retardation plate 2, and irradiates the liquid crystal display panel 4. .

  At this time, the light irradiated from the fine phase difference plate 2 is emitted so as not to spread in the vertical direction and is applied to the liquid crystal display panel 4. That is, the light transmitted through a specific area of the fine retardation plate is transmitted through a specific display unit portion of the liquid crystal display panel 4.

  Of the light irradiated on the liquid crystal display panel 4, the light passing through the right region 11 a and the light passing through the left region 11 b of the polarizing filter 11 are incident on the Fresnel lens 12 at different angles. The light is refracted and emitted from the liquid crystal display panel 4 along different paths.

  The liquid crystal display panel 4 has a liquid crystal that is twisted and aligned at a predetermined angle (for example, 90 degrees) between two transparent plates (for example, glass plates). It is composed. The light incident on the liquid crystal display panel is emitted with the polarization of the incident light shifted by 90 degrees in a state where no voltage is applied to the liquid crystal. On the other hand, in a state where a voltage is applied to the liquid crystal, the twist of the liquid crystal can be solved, so that incident light is emitted as it is with polarized light.

  A fine phase difference plate 2 and a polarizing plate 3 (second polarizing plate) are arranged on the light source 1 side of the liquid crystal display panel 4, and a polarizing plate 5 (first polarizing plate) is arranged on the viewer side. ing.

  In the fine phase difference plate 2, regions for changing the phase of transmitted light are repeatedly arranged at fine intervals. Specifically, the light-transmitting base material 22 is provided with a region 2a in which a half-wave plate 21 having a fine width is provided, and at a fine interval equal to the width of the half-wave plate 21, 1 / The region 2b where the two-wave plate 21 is not provided is repeatedly provided at a fine interval. That is, the region 2a that changes the phase of light transmitted by the provided half-wave plate and the region 2b that does not change the phase of light transmitted because the half-wave plate 21 is not provided are finely spaced. It is provided repeatedly. This half-wave plate functions as a phase difference plate that changes the phase of transmitted light.

  The half-wave plate 21 is disposed so that its optical axis is inclined 45 degrees with respect to the polarization axis of the light transmitted through the right region 11a of the polarization filter 11, and the polarization axis of the light transmitted through the right region 11a is rotated by 90 degrees. And exit. That is, the polarization axis of the light transmitted through the right region 11a is rotated by 90 degrees so as to be equal to the polarization of the light transmitted through the left region 11b. That is, the region 2b where the half-wave plate 21 is not provided transmits light having the same polarization as the polarizing plate 3 that has passed through the left region 11b, and the region 2a where the half-wave plate 21 is provided Light that has passed through the right region 11 a and whose polarization axis is orthogonal to the polarization plate 3 is rotated so as to be equal to the polarization axis of the polarization plate 3 and emitted.

  The repetition of the polarization characteristics of the fine retardation plate 2 is such that the polarization of light transmitted for each display unit (that is, for each horizontal line in the horizontal direction of the display unit) is set at substantially the same pitch as the display unit of the liquid crystal display panel 4. To be different. Therefore, the polarization characteristics of the fine phase difference plate corresponding to each horizontal line (scanning line) of the display unit of the liquid crystal display panel 4 are different, and the direction of the emitted light is different for each horizontal line.

  Alternatively, the repetition of the polarization characteristics of the fine retardation plate 2 is performed by setting the polarization characteristics of the fine retardation plate 2 to a plurality of display units (that is, a plurality of display units) as a pitch that is an integral multiple of the display unit pitch of the liquid crystal display panel 4 It is set so that the polarization of the transmitted light is different for each of the plurality of display units. Therefore, the polarization characteristics of the fine retardation plate are different for each of the plurality of horizontal lines (scanning lines) of the display unit of the liquid crystal display panel 4, and the direction of the light emitted is different for each of the plurality of horizontal lines.

  Thus, since it is necessary to irradiate the display element (horizontal line) of the liquid crystal display panel 4 with different light every time the polarization characteristics of the fine retardation plate are repeated, the liquid crystal display panel 4 transmits through the fine retardation plate 2. It is necessary that the light radiated on the surface is one that suppresses diffusion in the vertical direction.

  That is, the region 2a of the fine phase difference plate 2 that changes the phase of the light transmits the light transmitted through the right region 11a of the polarizing filter 11 with the same polarization as the light transmitted through the left region 11b. Further, the region 2b in the fine phase difference plate 2 where the phase of the light is not changed transmits the light transmitted through the left region 11b of the polarizing filter 11 as it is. The light emitted from the fine phase difference plate 2 has the same polarization as the light transmitted through the left region 11 b and enters the polarizing plate 3 provided on the light source side of the liquid crystal display panel 4.

  The polarizing plate 3 functions as a second polarizing plate and has a polarization characteristic that transmits light having the same polarization as the light transmitted through the fine retardation plate 2. That is, the light that has passed through the left region 11b of the polarizing filter 11 passes through the second polarizing plate 3, and the light that has passed through the right region 11a of the polarizing filter 11 has its polarization axis rotated by 90 degrees to pass through the second polarizing plate 3. To Penetrate. The polarizing plate 5 functions as a first polarizing plate and has a polarization characteristic that transmits light having a polarization different from that of the polarizing plate 3 by 90 degrees.

  The fine retardation plate 2, the polarizing plate 3 and the polarizing plate 5 are bonded to the liquid crystal display panel 4, and the fine retardation plate 2, the polarizing plate 3, the liquid crystal display panel 4 and the polarizing plate 5 are combined to form an image display device. Configure. At this time, in a state where a voltage is applied to the liquid crystal, the light transmitted through the fine retardation plate 2 is transmitted through the polarizing plate 5. On the other hand, in a state in which no voltage is applied to the liquid crystal, the light transmitted through the fine retardation plate 2 is not transmitted through the polarizing plate 5 because the polarized light is twisted 90 degrees and emitted from the liquid crystal display panel 4.

  The diffuser 6 is attached to the front side (observer side) of the first polarizing plate 5 and functions as a diffusing unit that diffuses light transmitted through the liquid crystal display panel in the vertical direction. As an example of the diffuser 6, light transmitted through the liquid crystal display panel is diffused up and down using a lenticular lens in which kamaboko-shaped irregularities are repeatedly provided in the vertical direction.

  FIG. 2 is a block diagram showing a drive circuit of the image display apparatus according to the embodiment of the present invention.

These CPU 101, ROM 102 and RAM 103 are connected by a bus 108. The bus 108 includes an address bus and a data bus that are used by the CPU 101 for reading and writing data.

  A communication interface 105 that controls input / output with the outside, an input interface 106, and an output interface 107 are connected to the bus 108. The communication interface 105 is a data input / output unit for performing data communication according to a predetermined communication protocol. The input interface 106 and the output interface 107 input / output image data to be displayed on the image display device 8.

  In addition, a graphic display processor (GDP) 156 of the display control circuit 150 is connected to the bus 108. The GDP 156 calculates the image data generated by the CPU 101, writes it in a frame buffer provided in the RAM 153, and outputs signals to the image display device 8 (image signal RGB, vertical synchronization signal V_SYNC, horizontal synchronization signal H_SYNC, L / R signal). A ROM 152 and a RAM 153 are connected to the GDP 156, and a work buffer for operating the GDP 156 and a frame buffer for storing display data are provided in the RAM 153. The ROM 152 stores programs and data necessary for the GDP 156 to operate.

  Further, an oscillator 158 that supplies a clock signal to the GDP 156 is connected to the GDP 156. The clock signal generated by the oscillator 158 defines the operation period of the GDP 156, and generates the period of the synchronization signal (for example, the vertical synchronization signal V_SYNC) output from the GDP 156.

  The RGB signal output from the GDP 156 is input to the γ correction circuit 159. The γ correction circuit 159 corrects the non-linear characteristic of the illuminance with respect to the signal voltage of the image display device 8, adjusts the display illuminance of the image display device 8, and generates an RGB signal to be output to the image display device 8. .

  The composite conversion device 170 is provided with a right-eye frame buffer, a left-eye frame buffer, and a stereoscopic frame buffer. When the L / R signal sent from the GDP 156 indicates “R”, the right-eye image is displayed. When the L / R signal indicates “L”, the left-eye image is written into the left-eye frame buffer. Then, the right-eye image and the left-eye image are combined to generate a stereoscopic image, which is written into the stereoscopic frame buffer, and the stereoscopic image data is output to the image display device 8 as an RGB signal.

  The generation of the stereoscopic image by combining the right-eye image and the left-eye image is combined with the right-eye image and the left-eye image at every interval of the half-wave plate 21 of the fine phase difference plate 2. Specifically, since the half-wave plate 21 of the fine retardation plate 2 of the image display device 8 of the present embodiment is arranged at intervals of the display unit of the liquid crystal display panel 4, the display of the liquid crystal display panel 4 is performed. The stereoscopic image is displayed so that the right-eye image and the left-eye image are alternately displayed for each unit horizontal line (scanning line).

  The left-eye image data transmitted from the GDP 156 during the output of the L signal is written into the left-eye frame buffer, and the right-eye image data transmitted from the GDP 156 during the output of the R signal is written into the right-eye frame buffer. Then, the left-eye image data written in the left-eye frame buffer and the right-eye image data written in the right-eye frame buffer are read for each scanning line and written into the stereoscopic frame buffer.

  In the image display device 8, a liquid crystal driver (LCD DRV) 181 and a backlight driver (BL DRV) 182 are provided. The liquid crystal driver (LCD DRV) 181 sequentially applies voltages to the electrodes of the liquid crystal display panel based on the V_SYNC signal, the H_SYNC signal, and the RGB signal sent from the composite conversion device 170, so that the liquid crystal display panel is used for stereoscopic viewing. Display a composite image.

  The backlight driver 182 changes the brightness ratio of the liquid crystal display panel 4 by changing the duty ratio of the voltage applied to the light emitting element (backlight) 10 based on the DTY_CTR signal output from the GDP 156.

  As shown in FIG. 5, the light emitting element 10 includes a plurality of light emitting elements of a left eye light emitting element 10L and a right eye light emitting element 10R. The GDP 156 and the backlight driver 182 include the left eye light emitting element 10L and the light emitting element 10L. The right-eye light emitting element 10R is controlled by an independent duty ratio signal (DTY_CTR signal), and the luminance of the left and right light emitting elements can be arbitrarily changed.

  FIG. 3 shows a synthesizing conversion apparatus 170, which is provided with a control unit 171, a RAM 172, and a ROM 173 having a microprocessor. The RAM 172 has a right-eye frame buffer 175, a left-eye frame buffer 174, and a stereoscopic frame buffer 177. Is set.

  Based on the L / R signal from the CPU 151 and the vertical synchronization signal V_SYNC from the GDP 156, the control unit 171 writes the right-eye image sent from the GDP 156 to the right-eye frame buffer 175 and the left-eye image to the left-eye frame buffer. Write to 174.

  Next, the control unit 171 writes the image data stored in the left and right frame buffers 174 and 175 into the stereoscopic frame buffer 177 in synchronization with the vertical synchronization signal V_SYNC to synthesize the right eye image and the left eye image. Then, a stereoscopic image (three-dimensional image) is generated, and the stereoscopic image data is output to the image display device 8 as an RGB signal or the like.

  The L / R signal indicates, for example, left-eye image data when Hi level = 1, and right-eye image data when Lo level = 0.

  The generation of the stereoscopic image by combining the right-eye image and the left-eye image is performed at every interval of the half-wave plate 21 provided in the fine retardation plate 2 as shown in FIG. And the left eye image. Specifically, since the half-wave plate 821 of the fine retardation plate 2 of the image display device 8 of the present embodiment is arranged at intervals of the display unit of the liquid crystal display panel 4, the display of the liquid crystal display panel 4 is performed. The stereoscopic image is displayed so that the right-eye image and the left-eye image are alternately displayed for each unit horizontal line (scanning line).

  In a normal display state, the left-eye image data transmitted from the GDP 156 during output of the L signal is written to the left-eye frame buffer 174, and the right-eye image data transmitted from the GDP 156 during output of the R signal is stored in the right-eye frame buffer. Write to 175. Then, the left-eye image data written in the left-eye frame buffer 174 and the right-eye image data written in the right-eye frame buffer 175 are read for each scanning line and written into the stereoscopic frame buffer 177.

  FIG. 4 is a front view showing the fine retardation plate 2 of the image display device according to the embodiment of the present invention.

  The fine retardation plate 2 is provided with a half-wave plate, and regions for changing the polarization of transmitted light are repeatedly and continuously arranged at fine intervals at predetermined intervals. The polarization of the light incident on the repeatedly arranged region is different in the right region 11a and the left region 11b of the polarization filter 11, and the polarization axis of the incident light is 90 degrees in the region where the polarization of the transmitted light is changed. Rotate and emit. The repetition of the polarization characteristic of the fine phase difference plate 2 is set to substantially the same pitch as the display unit of the liquid crystal display panel 4.

  That is, light that has passed through the right region 11a of the polarizing filter 11 and whose polarization axis has been rotated 90 degrees with the fine phase plate, and light that has passed through the left region 11b of the polarizing filter 11 and has passed through the fine phase plate as it is. Are equal to each other, and these lights are transmitted through the second polarizing plate. The area of the fine retardation plate 2 that changes the polarization of the transmitted light and the area that does not change the polarization of the transmitted light are repeatedly and continuously arranged for each horizontal line of the display unit of the liquid crystal display panel 4. The light transmitted through the fine retardation plate 2 and the second polarizing plate 3 becomes the light having the same polarization directed in different directions for each horizontal line.

  As described above, the polarization characteristic of the fine phase difference plate 2 is repeated as an integral multiple of the pitch of the display unit of the liquid crystal display panel 4, and the polarization characteristic of the fine phase difference plate 2 is set for each of a plurality of display units. It is also possible to change the polarization of transmitted light for each of a plurality of display units.

  FIG. 5 is a plan view showing an optical system of the image display apparatus according to the embodiment of the present invention. FIG. 6 is a diagram for explaining the path of light emitted from the image display device according to the embodiment of the present invention. FIG. 6A passes through the right region 11a of the polarizing filter and reaches the left eye. FIG. 6 (b) shows the light path that passes through the left region 11b of the polarizing filter and reaches the right eye.

  As shown in FIG. 5, the light emitted from the light emitting element 10 passes through the polarizing filter 11 and spreads radially. Of the light emitted from the light source, the light transmitted from the left-eye light emitting element 10L through the right region 11a of the polarizing filter 11 (indicated by the one-dot chain line indicates the center of the optical path) reaches the Fresnel lens 12, and the light is transmitted by the Fresnel lens 12. By changing the traveling direction, the light passes through the fine retardation plate 2, the polarizing plate 3, the liquid crystal display panel 4, and the polarizing plate 5 substantially vertically (slightly from the right side to the left side) and reaches the left eye.

  On the other hand, of the light emitted from the light source, the light transmitted from the right-eye light emitting element 10R through the left region 11b of the polarizing filter 11 (shown by the broken line indicates the center of the optical path) reaches the Fresnel lens 12 and is emitted by the Fresnel lens 12. The traveling direction is changed, and the fine phase difference plate 2, the polarizing plate 3, the liquid crystal display panel 4, and the polarizing plate 5 are transmitted substantially vertically (slightly from the left side to the right side) to reach the right eye.

  In this way, the light emitted from the left and right light emitting elements 10L and R constituting the light emitting element 10 and transmitted through the polarizing filter 11 is irradiated to the liquid crystal display panel 4 substantially perpendicularly by the Fresnel lens 12 as an optical means. ing. That is, the light source 1, the polarizing filter 11, and the Fresnel lens 12 constitute the light source 1 that irradiates the liquid crystal display panel 4 with light having different polarization planes substantially vertically and through different paths, and transmitted through the liquid crystal display panel 4. Light is emitted in different ways to reach the right or left eye. That is, the scanning line pitch of the liquid crystal display panel 4 is made equal to the repetition pitch of the polarization characteristics of the fine retardation plate 2, and the light arriving from different directions is irradiated for each scanning line pitch of the liquid crystal display panel 4. Light is emitted in the direction.

  As shown in FIG. 6A, the light emitted from the left-eye light emitting element 10L and transmitted through the right region 11a of the polarizing filter is transmitted through the Fresnel lens 12, reaches the fine retardation plate 2, and is polarized. Transmitting through the region 2a of the fine phase difference plate 2 that is emitted by rotating 90 degrees (transmitting the light transmitted through the right region 11a), further passing through the polarizing plate 3, the liquid crystal display panel 4, and the polarizing plate 5, It reaches the left eye. That is, the left eye image displayed by the display element at a position corresponding to the region 2a of the liquid crystal display panel 4 reaches the left eye.

  Since the regions 2b arranged alternately with the regions 2a of the fine retardation plate 2 do not change the polarization of light, the light from the right region 11a of the polarizing filter does not pass through the polarizing plate 3 and is displayed on the liquid crystal display. The right eye image displayed on the display element at the position corresponding to the region 2b of the panel 4 does not reach the left eye.

  On the other hand, as shown in FIG. 6B, the light emitted from the right-eye light emitting element 10R and transmitted through the left region 11b of the polarizing filter passes through the Fresnel lens 12 and reaches the fine retardation plate 2, The left side region 11b of the polarizing filter is transmitted through the region 2b of the fine retardation plate 2 that transmits the same polarized light, is transmitted through the liquid crystal display panel 4 and the polarizing plate 5, and reaches the right eye. That is, the right eye image displayed by the display element at a position corresponding to the region 2b of the liquid crystal display panel 4 reaches the right eye.

  Since the regions 2a arranged alternately with the regions 2b of the fine retardation plate 2 change the polarization of light, the light from the left region 11b of the polarizing filter does not pass through the polarizing plate 3 and is displayed on the liquid crystal display. The left eye image displayed on the display element at the position corresponding to the region 2a of the panel 4 does not reach the right eye.

  FIG. 7 shows an example of the display of a three-dimensional image. FIG. 7A shows a three-dimensional image 850 (from the display surface 8A of the image display device 8 in the depth direction (Z-axis direction in the figure) on the viewer side. For example, when a virtual image (three-dimensional image) is displayed so that the image 850 pops up from the display surface 8A to the position of Z1 in the figure toward the viewer side in an example of displaying “3”) Thus, the image 850 is substantially at the center of the display surface 8A.

  Here, the image 850 shows a case where it is configured by the character “3”, and in the figure, the X axis is the horizontal direction (horizontal scanning direction) of the display surface 8A, the Y axis is the vertical direction (vertical scanning direction), and the Z axis is Depth direction is shown.

  The image 850 is data stored in the font ROM 157, and relative coordinates (horizontal coordinates and vertical coordinates) are defined in advance. The image 850 is displayed on the display space (viewpoint coordinate system) according to the Z-axis position and size. Are converted to the coordinates (XYZ coordinates).

  When the image 850 is displayed as a three-dimensional image in this way, as shown in FIGS. 7B and 7C, the right-eye image 850R observed with the right eye and the left-eye image 850L observed with the left eye are displayed on the display surface 8A. The images 850R and 850L are actually displayed, and are displayed with a predetermined amount dx shifted from the horizontal position of the three-dimensional image 850 observed by the observer.

  That is, the left-eye image 850L is displayed at a position shifted by + dx on the right side in the drawing from the horizontal position (the center of the X axis of the display surface 8A) of the three-dimensional image 850 in FIG. 7C. 850R is displayed at a position shifted by -dx on the left side in the drawing from the horizontal position of the three-dimensional image 850, and the positions of the left and right images 850L and R actually displayed on the display surface 8A are the three-dimensional image 850. Is displayed with a shift of 2dx according to the position in the depth direction (protrusion amount Z1).

  Therefore, in FIG. 7C, the position of the three-dimensional image 850 in the Z-axis direction is controlled by changing the amount of deviation (parallax of the right and left eyes) 2dx in the X-axis direction between the left-eye image 850L and the right-eye image 850R. can do. For example, in order to move the 3D image 850 displayed at the position of FIG. 7A to the display surface 8A side (direction away from the observer), the shift amount (coordinate parameter) 2dx may be decreased. Conversely, in order to move to the observer side, the shift amount 2dx may be increased. Further, in order to further protrude the image 850 of FIG. 7A from the display surface 8A to the observer side, the three-dimensional image 850 is further increased to the left-eye image 850L by increasing the positive shift amount (right side in the figure) + dx, In the right-eye image 850R, the negative shift amount (right side in the figure) -dx is increased. Conversely, to display the three-dimensional image 850 on the opposite side of the display surface 8A (the back side of the liquid crystal display panel 4), a negative shift amount (left side in the figure) -dx is given to the left-eye image 850L, and the right-eye image is used. A positive shift amount (left side in the figure) + dx may be given to the image 850R, and the stereoscopic image (virtual image) 850 observed by the observer is the horizontal shift amount 2dx between the left-eye image 850L and the right-eye image 850R. Is generated from

  In FIG. 7B, the left-eye image 850L and the right-eye image 850R are illustrated as overlapping on the same line for the sake of simplicity, but actually, as shown in FIG. 7C, A line for displaying the left-eye image 850L and a line for displaying the right-eye image 850R are preset according to the vertical position of the horizontal line of the liquid crystal display panel 4, and the left-eye image 850L and the right-eye image 850R are alternately arranged. (For example, every other line) and do not overlap on the same horizontal line.

  FIG. 8 is a graph showing the timing of each signal in the composite conversion device 170 and the image display device 8 from the display control circuit 150 (GDP 156).

  The vertical synchronization signal V_SYNC is supplied to indicate the scanning start timing of image data. The vertical synchronization signal V_SYNC becomes ON (LO level) every predetermined cycle (for example, 16.7 msec = 1/60 seconds).

  In the image display device 8, scanning of the scanning line is started at the falling timing of the vertical synchronization signal V_SYNC in accordance with the vertical synchronization signal V_SYNC (V1, V2, V3... In the figure), and image data is displayed.

  The L / R signal is a signal transmitted from the display control circuit 150 to the composite conversion device 170, and indicates whether the image signal currently being output from the GDP 156 (DATA in the figure) is an image for the left eye or an image for the right eye. Means the left eye image (L), and in the Low state, it means the right eye image (R).

  That is, as for the image data transmitted from the display control circuit 150 to the composite conversion device 170, the left-eye image and the right-eye image are alternately transmitted according to the L / R signal.

  The synthesizing / converting device 170 takes in the image data transmitted from the display control circuit (GDP 156) according to the switching timing of the L / R signal, and writes it into the left-eye frame buffer 175 or the left-eye frame buffer 174. Note that a separate trigger signal may be provided for the composite conversion device 170 to capture image data.

  Then, the data corresponding to the odd-numbered scanning lines (horizontal lines) of the left-eye image data and the data corresponding to the even-numbered scanning lines of the right-eye image data are transferred to the stereoscopic frame buffer 177 for stereoscopic viewing. Composite image data.

  The stereoscopic image data stored in the stereoscopic frame buffer 177 is output to the image display device 8 (LCD driver 181) in accordance with the timing of the next vertical synchronization signal V_SYNC.

  Thus, the left and right images are alternately updated for each vertical synchronization signal V_SYNC, and the updated image is output to the image display device 8 (liquid crystal panel 4) with the next vertical synchronization signal V_SYNC.

  For example, in FIG. 8, the right-eye image R1 received by the vertical synchronization signal V2 is combined with the left-eye image L1 received by the previous vertical synchronization signal V1, and then the next vertical synchronization signal V3 is used as an image of L1 + R1. The image is output from the composite conversion device 170 to the image display device 8, and the right-eye image is replaced with a new image. Then, the new left-eye image L2 received by the vertical synchronization signal V3 is output as an L2 + R1 image by the next vertical synchronization signal V4, and the left-eye image is replaced with a new image. Thus, in the image display device 8, either the left-eye image or the right-eye image is sequentially updated for each vertical synchronization signal V_SYNC.

Next, FIG. 9 alternately outputs left and right images for each vertical synchronization signal, and when the image is switched to a new image, the luminance (output) of the light emitting element corresponding to the updated image is temporarily set. An example of light emission control to be reduced is shown.

FIG. 9 shows display of left and right images performed on the liquid crystal panel 4 from the GDP 156 via the composite conversion device 170, and light emission of the left-eye light emitting element 10L (L light source in the figure) and the right-eye light emitting element 10R (R light source in the figure). It is a timing chart which shows the mode of control.

  Further, the output buffer in the figure shows the stereoscopic frame buffer 177 shown in FIG. 3, the left eye line shows the content of data corresponding to the odd-numbered scanning lines of the liquid crystal display panel 4, and the right eye line shows the liquid crystal display panel. 4 shows the contents of data corresponding to the even-numbered scanning lines of 4.

  In the drawing, LCD_OUT indicates the content of data output to the liquid crystal display panel 4, and LmRn (m and n are natural numbers) indicates a combination of the left-eye image data Lm and the right-eye image data Rn to be displayed. .

  Further, the L light source and the R light source indicate duty ratio signals of the left eye light emitting element 10L and the right eye light emitting element 10L (in this case, ON duty), 100% is completely turned on, 50% is lit in half, and 0% is turned off. Thus, the duty ratios of the left and right light emitting elements 10L and 10R are respectively controlled by independent DTY_CTR signals from the GDP 156.

  In FIG. 9, vertical synchronization in which the left-eye image data L1 received by the vertical synchronization signal V1 shown in FIG. 8 and the right-eye image data R1 received by the vertical synchronization signal V2 are stored in the stereoscopic frame buffer 177. The signal V3 and subsequent signals are shown.

  With the vertical synchronization signal V3, the right-eye image data R1 received by the vertical synchronization signal V2 from the right-eye frame buffer 175 in FIG. 3 is written to the right-eye line of the stereoscopic frame buffer 177, and the left-eye image data is displayed on the liquid crystal display panel 4. An image signal obtained by synthesizing L1 and right-eye image data R1 is transmitted.

  Next, as the vertical synchronization signal V4, the left-eye image data L2 received by the vertical synchronization signal V3 from the left-eye frame buffer 174 in FIG. 3 is written to the left-eye line of the stereoscopic frame buffer 177, and the left-eye image data is displayed on the liquid crystal display panel 4. An image signal obtained by synthesizing the image data for L2 and the image data for right eye R1 is transmitted.

  Further, with the vertical synchronization signal V5, the right-eye image data R2 received by the vertical synchronization signal V4 from the right-eye frame buffer 175 is written to the right-eye line of the stereoscopic frame buffer 177, and the left-eye image data L2 is stored in the liquid crystal display panel 4. And an image signal obtained by synthesizing the right-eye image data R2.

  Thereafter, the left eye line of the stereoscopic frame buffer 177 is updated when the vertical synchronization signal Vi is i = even, and the right eye line is updated when i = odd.

  Here, the GDP 156 reduces the duty ratio of the left-eye light emitting element 10L (for example, 50%) when the vertical synchronization signal Vi is i = even, and sets the duty ratio of the right-eye light emitting element 10R to 100% of complete lighting. When the vertical synchronizing signal Vi is an odd number, the duty ratio of the right-eye light emitting element 10R is reduced (for example, 50%), the duty ratio of the left-eye light emitting element 10L is set to 100% of full lighting, and the left and right light emitting elements 10L The luminance of 10R is changed alternately.

  As a result, the updated image data is displayed darkly, and the image recognition of the updated dark image is delayed as compared with the bright image that is not updated. That is, by using the difference in perceptual reaction time depending on luminance (perception is delayed when luminance is low), the generation time lag of images that are alternately updated every 1/60 is reduced by the perception time lag. Therefore, when the newly updated left-eye image is different from the right-eye image (for example, L2R1 of the vertical synchronization signal V4, L3R2 of V6, etc.), it is possible to suppress discomfort to the observer.

  FIG. 10 shows a display in which the left and right images are alternately output for each vertical synchronization signal, and the luminance (output) of the light emitting element corresponding to the updated image is temporarily reduced when the image is switched to a new image. The input data of the composite conversion device is shown on the left side in the figure, and the display state of the liquid crystal display panel 4 is shown on the right side in the figure.

  In the vertical synchronization signal V3, as shown on the left side in the figure, the left-eye image data L1 and the right-eye image data R1 received by the vertical synchronization signals V1 and V2 are displayed on the liquid crystal display panel 4 as shown on the right side in the figure. The left-eye image L1 ′ and the right-eye image R1 ′ are displayed in the area. In FIG. 10, the left-eye image and the right-eye image are shown as different display areas for the sake of explanation. Actually, as shown in FIG. 7C, the left and right images are actually displayed in the same display area. Are displayed alternately on the right and right eye lines.

  In the vertical synchronization signal V3, as shown in FIG. 9, since the vertical synchronization signal Vi is i = odd, the duty ratio of the right-eye light emitting element 10R is reduced (for example, 50%), while the left-eye light emitting element is used. When the duty ratio of 10L is 100% of complete lighting, the left-eye image L1 ′ is displayed brightly with normal luminance, and the right-eye image R1 ′ is displayed darkly with lower luminance than normal.

  Next, in the vertical synchronization signal V4, as shown on the left side in the figure, the left-eye image data L2 and the right-eye image data R1 received by the vertical synchronization signals V2 and V3 are displayed on the liquid crystal display panel as shown on the right side in the figure. 4 are displayed as a left-eye image L2 ′ and a right-eye image R1 ′, respectively, and the left-eye image is updated from L1 ′ to L2 ′.

  In the vertical synchronizing signal V4, since the vertical synchronizing signal Vi is i = even, the duty ratio of the left-eye light emitting element 10L is reduced, while the duty ratio of the right-eye light emitting element 10R is set to 100% of full lighting and updated. The left-eye image L2 ′ is displayed dark with a lower brightness than normal, while the right-eye image R1 ′ is displayed bright with normal brightness.

  As a result, the left and right images with different update timings have a time lag until the left and right images become the same image, but the newly updated image is displayed darker. However, since the old image is displayed relatively brighter than the new image, the observer recognizes the old image more quickly, so the left and right images are different. Even the display content can prevent the viewer from feeling uncomfortable.

  In the above description, the left and right light emitting elements 10L and 10R are driven by duty control. However, the left and right light emitting elements 10L and 10R may be independently controlled by increasing and decreasing the current. In this case, there is no fear of occurrence of flicker due to duty control.

  11 to 13 show the second embodiment, in which the luminance of the left and right images in the first embodiment is changed based on a preset procedure such as sequence data. The configuration is the same as that of the first embodiment.

  FIG. 11 shows an example of sequence data for controlling the display of a gaming machine such as a pachinko machine, and the background and pattern to be displayed, the type and position of an object (such as a character), etc. are based on the passage of time (or frame). This is information to be instructed. This sequence data is stored in advance in storage means (ROM 152, RAM 103 or a disk device (not shown)) of the main control circuit 100, and the CPU 101 reads the sequence data and reads data based on the sequence data from the storage means to display position. Etc., and commands to the GDP 156 for drawing and light source control.

  Here, sequence data when the variable display game (display in which graphics and characters change by scrolling, etc.) is a big hit (a state in which preset graphics and characters are aligned) is shown. After changing the object such as a figure or a character with a pattern for a predetermined time and then temporarily stopping the symbol (substantially stopped), the screen shifts to a big hit occurrence notification screen after the symbol switching command 160.

  The symbol switching command 160 is not comfortable for the observer because the left and right images are temporarily different, as will be described later, when switching from the state where the objects are aligned (design stopped) to the initial screen for notifying the occurrence of jackpot. In order to suppress the application of the light, a command to temporarily darken either the left-eye light-emitting element 10L or the right-eye light-emitting element 10R corresponding to the newly updated image.

  Further, the sequence data includes the left-eye light-emitting element 10L or the right-eye light-emitting element 10R corresponding to the newly updated image in the same manner as described above when the jackpot occurrence notification screen is shifted to the jackpot effect screen. A symbol switching command 161 for temporarily darkening one of the screens is interposed, and when the screen changes greatly, either the left or right screen is temporarily darkened to smoothly connect two different screens.

  FIG. 12 shows display of left and right images performed on the liquid crystal panel 4 from the GDP 156 via the composite conversion device 170, and light emission of the left-eye light emitting element 10L (L light source in the figure) and the right-eye light emitting element 10R (R light source in the figure). It is a timing chart which shows the mode of control.

  Further, the output buffer in the figure shows the stereoscopic frame buffer 177 shown in FIG. 3, the left eye line shows the content of data corresponding to the odd-numbered scanning lines of the liquid crystal display panel 4, and the right eye line shows the liquid crystal display. The contents of data corresponding to the even-numbered scanning lines of panel 4 are shown.

  In the drawing, LCD_OUT indicates the content of data output to the liquid crystal display panel 4, and LmRn (m and n are natural numbers) indicates a combination of the left-eye image data Lm and the right-eye image data Rn to be displayed. .

  Further, the L light source and the R light source indicate the duty ratio of the left-eye light-emitting element 10L and the right-eye light-emitting element 10L (here, ON duty), 100% is completely lit, 50% is half the luminance, and the left and right light-emitting elements The duty ratios of 10L and 10R are controlled by an independent DTY_CTR signal from the GDP 156, respectively.

  FIG. 12 shows the state of control for each vertical synchronization signal, as in FIG. 8 of the first embodiment, and shows the vertical synchronization signal V3 and later for ease of explanation.

  With the vertical synchronization signal V3, the right-eye image data R1 received by the vertical synchronization signal V2 from the right-eye frame buffer 175 in FIG. 3 is written to the right-eye line of the stereoscopic frame buffer 177, and the left-eye image data is displayed on the liquid crystal display panel 4. An image signal obtained by synthesizing L1 and right-eye image data R1 is transmitted.

  Next, as the vertical synchronization signal V4, the left-eye image data L2 received by the vertical synchronization signal V3 from the left-eye frame buffer 174 in FIG. 3 is written to the left-eye line of the stereoscopic frame buffer 177, and the left-eye image data is displayed on the liquid crystal display panel 4. An image signal obtained by synthesizing the image data for L2 and the image data for right eye R1 is transmitted.

  Further, with the vertical synchronization signal V5, the right-eye image data R2 received by the vertical synchronization signal V4 from the right-eye frame buffer 175 is written to the right-eye line of the stereoscopic frame buffer 177, and the left-eye image data L2 is stored in the liquid crystal display panel 4. And an image signal obtained by synthesizing the right-eye image data R2.

  With the vertical synchronization signal V6, the left-eye image data L3 received by the vertical synchronization signal V5 from the left-eye frame buffer 174 is written to the left-eye line of the stereoscopic frame buffer 177, and the left-eye image data is displayed on the liquid crystal display panel 4. An image signal obtained by combining L2 and right-eye image data R1 is transmitted.

  Here, the left and right image data L2 and R2 are images in the symbol stop state, which is the final stage of the above-described variation display game, and the left and right image data L3 and R3 and later are switched to the jackpot occurrence notification image. Therefore, in the vertical synchronization signal V6, the GDP 156 reads the sequence data symbol switching command until the next vertical synchronization signal V7 is generated in order to darken the left-eye image L3 ′, which is a newly updated image. During this period, the duty ratio of the left-eye light emitting element 10L is reduced (for example, 50%). The duty ratio of the right-eye light emitting element 10R is maintained at 100% in order to maintain normal luminance.

  That is, the GDP 156 simultaneously generates the vertical synchronization signal V6, reduces the duty ratio of the left-eye light emitting element 10L, maintains this reduced state until the next vertical synchronization signal V7, and outputs the jackpot occurrence notification left-eye image L3 ′. Is displayed darker than the original brightness, while displaying the right-eye image R2 ′ of the variable display game while maintaining the normal brightness, and suppressing the observer from observing different images with the left and right eyes, A sense of incongruity can be reduced.

  Next, when the vertical synchronization signal V7 is generated, the GDP 156 has finished the sequence data switching command, so the duty ratio of the left-eye light emitting element 10L is returned to a normal value (here, 100%), Make the brightness of the left and right images equal.

  With this vertical synchronization signal V7, the left and right image data are the same frame at L3 and R3, and the image of the jackpot occurrence notification is displayed with normal luminance.

  Thus, when the image changes greatly in the sequence data, the switching command is inserted, and the GDP 156 that draws the image and controls the luminance of the light source receives the switching command, and the right and left corresponding to the newly updated image is received. Since the luminance of one of the light emitting elements 10L and 10R is reduced, when the left and right images having different update timings change significantly, the luminance of the newly updated image is temporarily reduced, and the perception of the updated image is performed. By delaying, it is possible to suppress the observation of different images between the left and right eyes, and to reduce the sense of discomfort given to the observer.

  FIG. 13 shows a display in which the left and right images are alternately output for each vertical synchronization signal, and when the image is switched from the variable display game to the jackpot occurrence notification, the brightness of the latest one is temporarily reduced on the screen at the time of switching. As an example, input data of the composite conversion device is shown on the left side in the figure, and the display state of the liquid crystal display panel 4 is shown on the right side in the figure.

  Up to the vertical synchronization signal V5, an image (the symbol stop in FIG. 11) in which the variable display game is fixed is displayed, and after the vertical synchronization signal V7, the number “3” is aligned, so that the big hit is informed. A jackpot occurrence notification image is displayed, and at the time of the vertical synchronization signal V6, the symbol display of the variable display game is switched to the jackpot occurrence notification image.

  In the vertical synchronization signal V6, the right-eye image R2 ′ is the right-eye image data R2 received by the vertical synchronization signal V4 and is the final state of the variable display game, whereas the left-eye image L3 ′ is the vertical synchronization signal V5. This is the left-eye image data L3 received in Step 1, and is the initial screen of the jackpot occurrence notification image. Therefore, while the right eye observes the state where the numbers “3” are aligned, the left eye observes the “big hit” character, but the duty of the left-eye light emitting element 10L is determined by a sequence data switching command. Since the ratio is temporarily reduced, the left-eye image L3 ′ is displayed darkly as illustrated.

  For this reason, the observer can recognize the image for the right eye brighter than the relatively dark left-eye image L3 ′ first, so that it is possible to suppress a sense of incongruity that the left and right images are completely different when the image changes greatly. .

  Here, the gaming machine will be described with reference to FIGS.

  FIG. 14 is a front view showing the overall configuration of a gaming machine (a CR machine with a card ball lending unit) showing an embodiment of the present invention, and FIG. 2 is a block diagram of a control system.

  A front frame 1003 of a gaming machine (pachinko gaming machine) 1001 is assembled to a main body frame (outer frame) 1004 through a hinge 1005 so as to be capable of opening and closing, and a gaming board 1006 is a storage frame (attached to the back of the front frame 1003). (Not shown).

  On the surface of the game board 1006, there are a variable display device (image display device) 1008, a variable winning device 1010 equipped with a big winning opening, a general winning opening 1011 to 1015, a starting opening 16, a normal symbol starting gate 27A, 27B, a normal symbol. A game area is formed in which the display 7, the normal variation winning device 9 (auxiliary winning means) and the like are arranged. A cover glass 18 that covers the front surface of the game board 1006 is attached to the front frame 1003.

  The variable display device 1008 is configured in the same manner as the image display device shown in FIG. 2, and includes the liquid crystal display panel 4 and the optical system shown in FIG.

  The variable display device 1008 displays three display symbols (identification information), for example, left, middle, and right, in the display area. For example, numbers “0” to “9” and alphabet letters “A” to “E” are assigned to these display symbols.

  When there is a winning game ball at the start port 16, the variable display device 1008 displays the display symbols (special symbols) composed of the above-described numbers and characters in order. When a winning at the start port 16 is made at a predetermined timing (specifically, when the special symbol random number counter value at the time of winning detection is a winning value), it is a big hit state and three display symbols are arranged. Stop in state (big hit symbol). At this time, the big prize opening of the variable prize winning device 1010 opens wide for a predetermined time (for example, 30 seconds), and a lot of game balls can be acquired.

  The winning of the game ball to the start port 16 is detected by a special symbol start sensor 51 (see FIG. 2). The passing timing of the game ball (specifically, the value of the special symbol random number counter provided in the game control device 1000 (see FIG. 2) at the time of winning detection) is used as the special symbol winning memory and the game control device 1000. Is stored in a predetermined storage area (special symbol random number storage area) within a predetermined maximum number of times. The number stored in the special symbol winning memory is displayed on the special symbol memory state display 17 including a plurality of LEDs provided on the lower side of the variable display device 1008. The game control device 1000 plays a variable display game with the variable display device 1008 based on the special symbol winning memory.

  The normal symbol display unit 7 starts to display a variation of a normal symbol (for example, a symbol consisting of one number) when a winning game ball is awarded to the normal symbol starting gates 27A and 27B. When winning to the normal symbol start gates 27A and 27B is made at a predetermined timing (specifically, when the normal symbol random number counter value at the time of winning detection is a winning value), it becomes a hit state related to the normal symbol, A normal symbol stops at a winning symbol (hit number). At this time, the normal variation winning device 9 provided in front of the starting port 16 opens wide for a predetermined time (for example, 0.5 seconds), and the winning possibility of the game ball to the starting port 16 is increased.

  The passing of the game ball to the normal symbol start gates 27A and 27B is detected by the normal symbol start sensor 52 (see FIG. 15). The passing timing of the game ball (specifically, the value at the time of passage detection of the normal symbol random number counter provided in the game control device 1000) is a predetermined memory in the game control device 1000 as the normal symbol winning memory. In the area (ordinary symbol random number storage area), a predetermined number of times (for example, a maximum of four consecutive times) is stored as a limit. The stored number of the normal symbol winning memory is displayed on the normal symbol storage state display 19 composed of a plurality of LEDs provided on the left and right of the normal symbol display 7. The game control device 1000 performs a winning lottery regarding the normal symbol based on the normal symbol winning memory. The number stored in the normal symbol storage state indicator 19 is set to an arbitrary value.

  An upper plate 1021 for supplying a ball to the ball hitting device is provided on the open / close panel 20 below the front frame 1003, and a lower plate 23, an operation unit 24 of the ball hitting device, and the like are provided on the fixed panel 1022.

  The front frame 1003 above the cover glass 18 is provided with a first notification lamp 31 and a second notification lamp 32 (see FIG. 15) that notify a state such as abnormal discharge of a sphere by lighting.

  The operation panel 26 for the card ball lending unit includes a card balance display unit (not shown) for displaying the card balance, a ball lending switch 28 for instructing ball lending, a card return switch 30 for instructing to return the card, and the like. Is provided.

  The card ball lending unit 1002 incorporates a card reader / writer and a ball lending control device for reading and writing data of a card (a prepaid card or the like) inserted in the card insertion unit 25 on the front surface. The operation panel 26 is formed on the outer surface of the upper plate 1021 of the gaming machine 1.

  FIG. 15 is a block configuration diagram showing a control system centering on the game control apparatus 1000.

  The game control device 1000 is a main control device that controls the game in an integrated manner, a CPU that controls game control, a ROM that stores invariant information for game control, and a RAM that is used as a work area during game control Is composed of a game microcomputer 1101, an input interface 1102, an output interface 1103, an oscillator 1104, and the like.

  The gaming microcomputer 1101 receives detection signals from various detection devices (special symbol start sensor 51, general prize opening sensors 55A to 55N, count sensor 54, continuation sensor 53, normal symbol start sensor 52) via the input interface 1102. In response, various processes such as a jackpot lottery are performed. And via the output interface 1103, various control devices (display control device 1150, discharge control device 200, decoration control device 250, sound control device 300), big prize opening solenoid 36, ordinary electric accessory solenoid 90, ordinary symbol display A command signal is transmitted to the device 7 and the like, and the game is comprehensively controlled.

  The discharge control device 200 controls the operation of the payout unit on the basis of a prize ball command signal from the game control device 1000 or a ball rental request from the card ball rental unit 1002 to cause the prize ball or the ball to be discharged.

  The decoration control device 250 controls a decoration light emitting device such as a decoration lamp and LED based on a decoration command signal from the game control device 1000, and also displays a special symbol memory display (special symbol hold LED) 18 and a normal symbol memory. The display of the display 19 is controlled.

  The sound control device 300 controls sound effect output from the speaker. Communication from the game control device 1000 to various subordinate control devices (display control device 1150, discharge control device 200, decoration control device 250, sound control device 300) is unidirectional from the game control device 1000 to the subordinate control device. Only communication is allowed. Thereby, it is possible to prevent an illegal signal from being input to the game control apparatus 1000 from the subordinate control apparatus side.

  The display control device 1150 constituting the display control means performs image display control in the same manner as the display control circuit of FIG. 2, and the same components are denoted by the same reference numerals. The display control device 1150 functions as a display control unit together with the composite conversion device 170.

  The display control device 1150 includes a CPU 151, a GDP 156, a RAM 153, an interface 155, a ROM 152 that stores programs, a font ROM 157 that stores image data (design data, background image data, moving image character data, texture data, etc.), a synchronization signal and a strobe. An oscillator 158 or the like that generates a timing signal or the like for generating a signal is included.

  The CPU 151 executes a program stored in the ROM 152, and based on a signal from the game control device 1000, image control information for a predetermined variable display game (symbol display information composed of sprite data, polygon data, etc., background screen) Information, moving image object screen information, etc.) to instruct the GDP 156 to generate an image.

  The GDP 156 performs, for example, image sprite drawing or polygon drawing (or normal bitmap drawing) based on the image data stored in the font ROM 157 and the contents calculated by the CPU 151 as a frame buffer. Store in the RAM 153.

  Then, the GDP 156 transmits the image in the RAM 153 to the LCD side (the composite conversion device 170) at a predetermined timing (vertical synchronization signal V_SYNC, horizontal synchronization signal H_SYNC).

  The rendering process performed by the GDP 156 is the same as in FIG. 2 described above, and the image signal is output to the synthesis conversion apparatus 170 via the γ correction circuit 159.

  Here, as the frame buffer, a plurality of frame buffers are respectively set in a predetermined storage area of the RAM 153, and the GDP 156 can be superimposed on an arbitrary image and output.

  The GDP 156 is connected to an oscillator 158 that supplies a clock signal. The clock signal generated by the oscillator 158 defines the operation period of the GDP 156. The GDP 156 divides this clock signal to generate a vertical synchronization signal (V_SYNC) and a horizontal synchronization signal (H_SYNC), and outputs them to the synthesis converter 170. At the same time, the GDP 156 outputs the vertical synchronization signal (V_SYNC) and the horizontal synchronization signal (H_SYNC) to the variable display device 1008 via the synthesis conversion device 170.

  The RGB signal output from the GDP 156 is input to the γ correction circuit 159. The γ correction circuit 159 corrects the non-linear characteristic of the illuminance with respect to the signal voltage of the variable display device 1008, adjusts the display illuminance of the variable display device 1008, and generates an RGB signal to be output to the variable display device 1008. .

  Further, the CPU 151 of the display control device 1150 determines whether the image data (RGB) to be output to the synthesis conversion device 170 is a left-eye image or a right-eye image based on the clock signal of the oscillator 158. An identifying L / R signal is output.

  Furthermore, the CPU 151 determines whether the variable display device 1008 has a variable display state (for example, whether it is a normal variable display game or a big hit display) or a game state (for example, a customer waiting state). In order to control the light emission amount (luminance), a duty control signal DTY_CTR is generated based on the clock signal of the oscillator 158 and output to the variable display device 1008.

  The synthesizing / conversion device 170 is provided with a right-eye frame buffer, a left-eye frame buffer, and a stereoscopic frame buffer. Based on the L / R signal sent from the GDP 156, the right-eye image is converted to the right-eye image. Write to the frame buffer for the left eye and write the image for the left eye to the frame buffer for the left eye. Then, the right-eye image and the left-eye image are combined to generate a stereoscopic image, which is written in the stereoscopic frame buffer, and the stereoscopic image data is output to the variable display device 1008 as an RGB signal.

  In the variable display device 1008, a liquid crystal driver (LCD DRV) 181 and a backlight driver (BL DRV) 182 are provided as in the image display device of FIG. The liquid crystal driver (LCD DRV) 181 applies voltage sequentially to the electrodes of the liquid crystal display panel 4 based on the V_SYNC signal, the H_SYNC signal, and the RGB signal sent from the synthesis conversion device 170, and stereoscopically displays the liquid crystal display panel 804 in a stereoscopic view. Display a composite image for

  The backlight driver 182 changes the brightness ratio of the liquid crystal display panel 4 by changing the duty ratio of the voltage applied to the light emitting element (backlight) 10 based on the DTY_CTR signal output from the CPU 151.

  Note that the game control device 1000 and the display control device 1150 function as a variable display control means for executing and outputting a variable display game. Alternatively, it functions as an effect control means for controlling the overall effect.

  The decoration control device 250 and the sound control device 300 may be subordinate to the display control device 1150, or the decoration control device 250 and the sound control device 300 may be mounted on the display control device 1150.

  FIG. 16 is a flowchart of the game, and the outline of the game will be described below with reference to this figure.

  First, at the beginning of the game (or before the game starts), the customer waiting state (specific state) is entered, and a signal for instructing the display of the customer waiting screen is transmitted from the game control device 1000 to the display control device 1150, On the screen of the variable display device 4, a customer waiting screen (model name of the gaming machine, a demonstration moving image or a still image using an appearing character) is displayed, and the player is prompted to play a game.

  Then, when a game ball launched into the game area of the game board 1006 wins the start opening 16, a predetermined random number is extracted by the game control device 1000 based on the winning, and a lottery drawing of the variable display game is performed. Then, the game control device 1000 transmits a signal for instructing the display control device 1150 to display the variable display, and the variable display of a plurality of symbols is started in the left, right, and middle variable display areas of the screen of the variable display device 1008.

  When a predetermined time elapses after the start of the variable display, the variable display is temporarily stopped in the order of, for example, left, right, and middle (for example, the pattern is slightly changed at the stop position). When a state (for example, a combination in which the left symbol and the right symbol may generate a jackpot combination) occurs, a predetermined reach game is performed. In this reach game, for example, the variation display of the inside symbol is performed at a very low speed, the variation is performed at a high speed, or the variation display is reversed. In addition, background display and character display in accordance with the reach game are performed.

  The temporary stop state is a state in which the player can recognize the symbol as a substantially stopped state, and the final stop mode is not determined. The stopped state includes the temporary stop state and the state in which the symbol is stopped. State. As a specific example of the temporary stop state, in addition to the slight fluctuation at the stop position, there are modes such as displaying the symbol in an enlarged scale, changing the color of the symbol, changing the shape of the symbol, and the like.

  If the result of the jackpot lottery is a jackpot, the symbols on the left, right, and center are finally stopped in a predetermined jackpot combination, and a jackpot game (a special game state advantageous to the player) is generated. When this jackpot game occurs, a special game is performed in which the variable winning device 11010 is opened for a predetermined period. This special game is executed with a predetermined number (for example, 10) of game balls to be awarded to the variable prize apparatus 11010 or the passage of a predetermined time (for example, 30 seconds) as one unit (one round). A prescribed round (for example, 16 rounds) is repeated on the condition that a winning is made to the continuous winning opening (detection of a winning ball by the continuous sensor 53). When a jackpot game is generated, a signal for instructing the display control device 1150 to display the jackpot game, such as a jackpot fanfare display, a round number display, a jackpot effect display, and the like is transmitted to the display control device 1150. The jackpot game is displayed on the screen.

  In this case, if the jackpot is a specific jackpot, a high probability state (probability fluctuation state) occurs after the jackpot game, and the probability of the next jackpot occurrence is made high, or based on winning the game ball at the start port 16 The variation display time of the variation display game of the variation display device 1008 is shortened.

  When the game ball wins the start opening 16 during the variable display game or the big hit game (when the special symbol start memory is generated), the big hit game ends after the variable display game ends (when it is lost) or After that, a new variation display game is repeated based on the special symbol start memory. Further, when the variable display game is finished (when lost), or when the big hit game is finished, when there is no special symbol start memory, the waiting state is returned to the customer.

  When the game ball passes through the normal symbol start gates 27A and B, a random number related to the normal symbol is extracted based on the passing or normal symbol start memory, and if the random number is correct, the normal symbol display 7 displays a hit. Thus, the normal variation winning device 9 at the start port 16 is expanded for a predetermined time, and winning at the start port 16 is facilitated.

  FIGS. 17 and 18 show a third embodiment. In place of light source control based on a preset procedure such as sequence data of the second embodiment, the lightness or saturation of an image is changed in the composite conversion device 170. FIG. The updated image is darkly displayed and the main control circuit 100 and the display control circuit 150 are controlled in the second embodiment except that the duty ratios of the left and right light emitting elements 10L and 10R are made constant. This is the same as the embodiment, and is performed based on the sequence data of FIG.

  FIG. 17 shows the storage area 177M of the stereoscopic frame buffer 177, the storage area 174M of the left-eye frame buffer 174, and the storage area 175M of the right-eye frame buffer 175 of the composition conversion apparatus 170.

  First, the storage area 177M of the stereoscopic frame buffer 177 includes a storage area M1 that stores pixels to be displayed on the image display device 8, and an area that is not actually used for display, and is not used for this display. In the area, storage areas ML and MR for storing determination information for determining whether the left and right images are largely switched are set.

  In the figure, ML is a storage area for storing determination information for the left-eye image. Similarly, MR in the figure is a storage area for storing determination information for the left-eye image. The left-eye image determination information storage area ML and the right-eye image determination information When black is set in the storage area MR, the composite conversion apparatus 170 reduces the lightness or saturation when outputting the line on which black is set from the display storage area M1 to the image display apparatus 8. While the filter process is performed to display the image darkly, if the storage area is set to white, the contents of the display storage area M1 are output as they are.

  For example, as shown in the figure, when black is set in the left-eye image determination information storage area ML and white is set in the right-eye image determination information storage area MR, of the image data in the display storage area M1 The left eye image is darkly displayed by performing filter processing for reducing the brightness or saturation of the left eye image data (left eye line), while the right eye image (right eye line) is output as it is.

  Note that if the brightness is lowered, it will eventually become black, and if the saturation is lowered, it will eventually become gray, but the preset value or the value set in the sequence data, etc. will be lowered to the lower limit. Shall be allowed to.

  Corresponding to the storage area 177M of the stereoscopic frame buffer 177, the display storage area LM1 and the determination information storage area LML are also set in the storage area 174M of the left eye frame buffer 174, and the storage area 175M of the right eye frame buffer 175 is set. In addition, the display storage area RM1 and the determination information storage area RMR are set, and the GDP 156 writes the left and right image data to the display storage areas LM1 and RM1 of the left and right frame buffers 174 and 175 according to the sequence data, and the sequence data. Black or white is written in the determination information storage area LML or RMR in accordance with the presence or absence of the switching command.

  Next, FIG. 18 is a timing chart showing the display of the left and right images and the control of the left-eye image or the right-eye image that are performed on the liquid crystal panel 4 from the GDP 156 via the synthesis conversion device 170.

  Similar to the second embodiment, the display of the confirmed state of the variable display game is performed up to the vertical synchronization signal V5 up to the image data L2 and R2, and after the vertical synchronization signal V7, the display of the jackpot occurrence notification is displayed as the image data L3, In the vertical synchronization signal V6, the left-eye image L3 is updated to the jackpot occurrence notification image, but the right-eye image remains the image data R2 in the confirmed state of the variable display game, and The images are very different.

  Here, the GDP 156 generates the left and right images of the sequence data and transmits them to the composition conversion device 170. When the sequence data switching command is read, the determination information is set to black in the image data L3 to be newly updated, The image data L3 is transmitted to the synthesis conversion device 170 together with the image data L3. The image data L3 is written in the display storage area LM1 of the left eye frame buffer 174, and the black determination information is written in the determination information storage area LML of the left eye frame buffer 174. . Although not shown, this operation is performed by the vertical synchronization signal V5.

  When the GDP 156 generates the vertical synchronization signal V6, the composite conversion device 170 transfers the contents of the display storage area LM1 of the left eye frame buffer 174 to the left eye line of the display storage area M1 of the stereoscopic frame buffer 177 and The contents of the determination information storage area LML of the frame buffer 174 are transferred to the left-eye determination information storage area ML of the stereoscopic frame buffer 177.

  When the composite conversion device 170 combines the left and right image data in the display storage area M1 and outputs them to the image display device 8, the composite conversion device 170 reads the left and right determination information storage areas ML and MR to determine whether or not it is black. Determine.

  In this case, since the left-eye determination information storage area ML is set to black, the image data of the left-eye line in the display storage area M1 is output after being subjected to filter processing for reducing the lightness or saturation while the right-eye line is output. Is output as is.

  As a result, in the vertical synchronization signal V6 at which the image is largely switched, the image data output to the image display device 8 is L3 + R2 and the left eye image L3 ′ is a big hit, as in FIG. 13 of the second embodiment. The right-eye image R2 ′ is in the final state of the variable display game and a different image is displayed while the notification image is a new image, but the composite conversion device 170 displays the brightness of the new image when the image is switched. Or, in order to temporarily reduce the saturation, the new image L3 ′ is temporarily displayed dark so that the observer cannot easily recognize it, as with the vertical synchronization signal V6 in FIG. Therefore, it is possible to suppress a sense of incongruity when the image is largely switched.

  In this case, the determination information for determining the switching time of the image is written in the non-display area together with the image data so that the process is performed on the composite conversion device 170 side. Therefore, the control content of the display control circuit 150 can be simplified. can do.

  FIG. 19 shows a fourth embodiment, in which switching commands such as sequence data of the third embodiment are set in a plurality of stages.

  In this case, the sequence data switching command has three steps: change amount = “large”, change amount = “small”, and no change. As in the third embodiment, “black” is written in the left or right determination information storage areas ML and MR, and “gray” is stored in the left or right determination information storage areas ML and MR when the change amount = “small”. If there is no change, “white” is written in the left or right determination information storage areas ML and MR.

  In the composite conversion device 170, if “black” determination information is written in the left or right determination information storage areas ML and MR, the brightness or saturation of the corresponding left eye line or right eye line is increased (for example, 50%). ) If the filter processing to reduce is performed and the determination information of “gray” is written, the filter processing to reduce the brightness or saturation of the corresponding left eye line or right eye line slightly (for example, 25%) is performed. Is output as it is without performing lightness or saturation filter processing.

  Thereby, when the change of the image is large, the image for the left eye or the right eye that is newly updated is made much darker than the other image to suppress the uncomfortable feeling of recognizing completely different images with the left and right eyes, When the change in the image is small, the newly updated left-eye or right-eye image is slightly darker than the other image, suppressing the uncomfortable feeling of recognizing a slightly different image with the left and right eyes, and brightness or saturation The display can be displayed without a sense of incongruity by suppressing a significant change in the image quality.

  FIG. 20 shows a fifth embodiment, in which the new image in the first to fourth embodiments is relatively darkened, the old image is brightened relatively to the new image, The recognition of a new image is suppressed when the images are different.

  FIG. 20 shows a case where the left and right light emitting elements 10L and 10R are controlled, and the duty ratio of the left and right light emitting elements 10L and 10R is darker than the rating (for example, 100%) (for example, 80%) during normal display. When the switching command is read from the sequence data as described above, the luminance of the light emitting element corresponding to the old image is increased to the duty ratio for screen switching (for example, 100%) to recognize a new image. Is to delay.

  That is, in FIG. 20, the left and right light emitting elements 10L and 10R are driven at a normal duty ratio such as 80% until the vertical synchronization signal V5, and the left-eye image L3 ′ is driven by the vertical synchronization signal V6 corresponding to the switching command. Since the right-eye image R2 ′ is an old image, the duty ratio of the right-eye light emitting element 10L is set to the screen switching duty ratio (100%), while the right-eye image R2 ′ is an old image. By maintaining the duty ratio of the light emitting element 10L for 80%, it becomes easy to recognize the old right-eye image R2 ′ while making it difficult to recognize the new left-eye image L3 ′.

  Thereafter, after the vertical synchronization signal V7, the duty ratios of the left and right light emitting elements 10L and 10R are returned to the normal ones, and the display at the normal brightness is continued.

  As a result, the observer clearly recognizes the old right-eye image R2 ′ having a high luminance, whereas the left-eye image L3 ′ having a low luminance is difficult to recognize. Therefore, when the left and right images change greatly, the old image By recognizing more clearly, the sense of incongruity caused by the difference between the left and right images is suppressed.

  In the above description, the luminance of the light source is controlled. However, as in the third or fourth embodiment, the lightness or saturation of the image may be changed by the synthesis conversion device 170, and the sequence data is switched. This is the same even if the composite conversion device 170 performs a filtering process to increase the brightness or saturation of an old image when a command is issued.

  FIG. 21 shows the sixth embodiment, in which the screen changes greatly based on the image level obtained from the left and right image data instead of the sequence data switching command of the second to fifth embodiments. An example of the control to determine is shown.

  FIG. 21 shows a subroutine for screen change determination control executed by the composite conversion apparatus 170, which is executed at a predetermined cycle (for example, every vertical synchronization signal).

  First, in step S12, RGB image data and L / R signal are read, and the received image data is written in either the left-eye frame buffer 174 or the right-eye frame buffer 175 in accordance with the L / R signal.

  Next, in step S13, RGB image data is converted into YCbCr image data.

  Here, YCbCr image data is obtained by converting Y = luminance, Cb = blueness (R−Y component), and Cr = redness (B−Y component) from RGB image data.

That is,
Y = LrR + LgG + LbB
Cb = (BY) / 2 (1-Lb)
Cr = (R−Y) / 2 (1−Lr)
However, Lr, Lg, and Lb are coefficients indicating the luminance of each primary color of RGB when the luminance of white is 1.

  Next, in step S14, the average value of one screen is obtained for each component of luminance Y, blue Cb, and red Cr, the average value of luminance Y is dn (Y), and the average value of blue Cb is dn (Cb). The average value of red Cr is obtained as dn (Cr).

  Next, in step S15, the luminance, blue, and red average values dn (Y), dn (Cb), and dn (Cr) of the current image obtained in step S14 are set as the current image level, and the previous image is obtained. Each average value of luminance, blue and red average values dn-1 (Y), dn-1 (Cb), dn-1 (Cr) is set as the previous image level, and each of the current image level and the previous image level is set. The absolute value of the difference is obtained for each element. The previous value is stored in the left and right frame buffers.

  The absolute value of the difference between the comparison data of the previous and subsequent image data is calculated as follows for luminance, blue, and red.

Difference in luminance = | dn (Y) −dn−1 (Y) |
Blue difference = | dn (Cb) −dn−1 (Cb) |
Red difference = | dn (Cr) −dn−1 (Cr) |
Next, in step S16 and subsequent steps, each difference obtained in step S15 is compared with a predetermined threshold value to determine whether the image change is large.

  First, in step S16, it is determined whether or not the luminance difference is larger than a predetermined value Yk. If it is larger than Yk, it is determined that the image change before and after is large, and the process proceeds to step S19. Then, the process proceeds to step S17.

  In step S17, it is determined whether or not the blue difference is larger than a predetermined value bk. If it is larger than bk, it is determined that the image change before and after is large, and the process proceeds to step S19. Proceed to step S18.

  In step S18, it is determined whether or not the red difference is larger than a predetermined value rk. If the red difference is larger than rk, it is determined that the image change before and after is large and the process proceeds to step S19. Proceed to step S20.

  In this step S20, the difference between the luminance, blue, and red is not more than the predetermined values Yk, bk, rk, and the image change is small. In this case, it is determined that there is no screen change because the screen switching control is not performed. .

  On the other hand, in step S19, since any one of luminance, blue, and red exceeds a predetermined threshold value, it is determined that the screen change is large.

  After the screen change is determined in step S19 or step S20, the contents of the frame buffer are updated using the current value of YCbCr as the previous value in step S21.

  Through the above processing, it is possible to detect the time point when the screen change becomes large without using sequence data based on the image data, and the relative brightness or saturation of a new image can be detected as in the second to fifth embodiments. Can be darkened.

  Alternatively, the above processing is performed with GDP 156, the duty ratios of the left and right light emitting elements 10L and 10R are changed according to the determination result of the screen change, and the brightness of the new image is made relatively dark compared to the old image. Also good.

  In the above embodiment, the two images are compared. However, the comparison data is calculated for a large number of images, the average value of these comparison data is obtained, and the absolute value of the difference between the current comparison data and the average value is calculated. From this, it may be determined that the image is changed.

  FIG. 22 shows a seventh embodiment. Instead of controlling the luminance, brightness, or saturation of the first to fifth embodiments, a new image is relatively displayed when a screen change is large using a liquid crystal shutter. The display is dark, and a liquid crystal shutter is added to the optical system shown in FIG. 1 of the first embodiment, and other configurations are the same as those of the first embodiment.

  In the optical system of FIG. 22, a liquid crystal shutter 40 is provided between a polarizing plate 5 and a diffuser 6 provided on the viewer side of the liquid crystal display panel 4 shown in FIG. 1 of the first embodiment. A polarizing plate 30 having the same polarization direction as that of the polarizing plate 3 is interposed between the shutter 40 and the diffuser 6. The polarizing characteristics of the polarizing plates 3 and 30 and the polarizing plate 5 are orthogonal to each other.

  Further, the liquid crystal display panel 4 and the liquid crystal shutter 40 for displaying an image are arranged so that the line for displaying the image for the left eye coincides with the line for displaying the image for the right eye.

  The liquid crystal shutter 40 is driven by the liquid crystal driver (LCD DRV) 181 shown in FIG. 2 of the first embodiment, and when applied to the first to sixth embodiments, when the screen change is large, The new image is relatively darkened by reducing the light transmittance of one of the left-eye line and the right-eye line corresponding to the newly updated image.

  In the above embodiment, the newly updated image is displayed so as to be relatively dark for a predetermined time. However, in the case of controlling the light source, it is darkened at the update timing and the original time is taken over the predetermined time. You may make it return to. In this way, the screen can be brightened rather than the entire screen darkened for a predetermined time.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
