Description

3D image partial display method and apparatus thereof {THE METHOD OF PARTIAL DISPLAY AND APPARATUS FOR STEREOSCOPIC IMAGE}

The present invention relates to a stereoscopic image display technology, and more particularly, to a stereoscopic image partial display method and apparatus for displaying a 2D image and a stereoscopic image of a predetermined size at the same time.

Advances in information and communication technology have enabled multimedia services that support two-dimensional video and voice to digital terminals that process text, voice, and video at high speeds. It is expected to develop.

In general, a three-dimensional image representing a three-dimensional image is made by the principle of stereo vision through two eyes.

An important factor of the three-dimensional effect is the parallax of binocular disparity, or binocular disparity, which appears because the human eyes are about 65 mm apart. Therefore, the left and right eyes see different two-dimensional images, and when the two images are transmitted to the brain through the retina, the brain fuses with each other to reproduce the depth and reality of the original three-dimensional image. This is commonly referred to as stereography.

The stereoscopic image display apparatus is largely classified into a stereoscopic stereoscopic image display apparatus and an autostereoscopic stereoscopic image display apparatus according to whether glasses are worn.

Spectacular stereoscopic image display apparatus must bear the inconvenience of observer wearing special glasses.

However, since the autostereoscopic 3D display device can feel a 3D image displayed directly on the screen without wearing the above-described glasses, it is possible to solve the disadvantage of the spectacle type 3D display device. An autostereoscopic 3D display device is largely classified into a lenticular device and a parallax-barrier device.

An operation of a stereoscopic image display device according to a conventional parallax-barrier method will be described with reference to FIGS. 1A and 1B. In the conventional parallax-barrier stereoscopic image display device, the left image L and the right image R facing the vertical direction (yy 'direction in FIG. The display module 10 alternately disposed in the direction xx 'of FIG. 1B), and a bar-shaped barrier layer facing the vertical direction called a barrier 20 at the front end thereof. In the 3D image display device, the display module 10 and the barrier 20 are disposed such that light corresponding to the left image L is incident only to the left eye, and light corresponding to the right image R is incident only to the right eye. In this way, the two left and right images (L, R) divided by the two observations are separately observed.

However, the conventional parallax-barrier stereoscopic image display device is based on the TFT-LCD display method, but the RGB display method of the TFT-LCD displays one pixel side by side in the horizontal direction (xx 'direction in FIG. 1B). Since R, G, and B are displayed in equal parts, some of R, G, and B may be hidden by the barrier 20 depending on the position and thickness of the barrier 20, thereby preventing the display of stereoscopic images. In some cases, the thickness and spacing of the barrier are limited to narrow the viewing angle of the stereoscopic image and the viewing distance is limited.

In addition, in the parallax-barrier method using a conventional liquid crystal module, a barrier is formed in the form of a vertical bar arranged side by side in the horizontal direction, and one segment terminal S and one common terminal C are formed for all pixels. By connecting and controlling all pixels on / off at the same time, the direction of barrier arrangement is inevitably fixed, so that stereoscopic images can be viewed only on a screen displaying images in a predetermined direction, and the screen is rotated in a horizontal / vertical direction. It is impossible to watch stereoscopic images.

In order to solve the above problems, the present invention can display a 2D image / stereoscopic image at the same time, and in particular, a stereoscopic image that allows a fixed display or a variable position of a stereoscopic image of a user-set size on a display screen. It is an object of the present invention to provide a partial display method and an apparatus thereof.

At least one input screen that can be displayed and a plurality of icons (corresponding to the plurality of partial screen forms pre-loaded in the manufacturing process of the display device) are displayed, so as to set a desired partial screen form; It is characterized by the configuration.
In addition, when the display size of the stereoscopic image partial screen is set, the number of barrier patterns corresponding to the display size is calculated when the configuration of the three-dimensional image partial screen is performed. And modifying the display control scheme to increase or decrease the number of patterns by one, and to correct the display size of the set stereoscopic image sub-screen.

Of course, there is an effect that can increase the added value of the device.

Hereinafter, the present invention will be described in detail with reference to the drawings. BRIEF DESCRIPTION OF THE DRAWINGS The accompanying drawings for the detailed description of the present invention are provided to enable those skilled in the art to easily understand the present invention, and the present invention is not limited to the accompanying drawings. Like reference numerals in the accompanying drawings denote like elements.

As shown in the block diagram of FIG. 2, the stereoscopic image display device according to an embodiment of the present invention is composed of a plurality of liquid crystal cells arranged in a horizontal and vertical direction to have a matrix structure, and according to a display control method. The cell column or the horizontal cell column of the liquid crystal unit 210 in which all or a portion of the column column is driven to form a barrier pattern, and the segment terminals S1 to S11 correspond to the vertical cell columns of the liquid crystal unit 210. Each of the plurality of driving terminals is connected to each of the segment terminals S1 to S11, the first liquid crystal driver 220 selectively driving the segment terminals S1 to S11 according to a display control method, and the liquid crystal unit ( A plurality of driving terminals are connected to each of the comb terminals C1 to C13 corresponding to each of the horizontal cell columns of 210, and the second liquid selectively drives the comon terminals C1 to C13 according to a display control method. Recognizes the setting of the stereoscopic image full screen mode or the stereoscopic image partial screen mode by the positive driver 230 and the input device (not shown), and the display device (not shown) when the stereoscopic image partial screen mode is set. Displaying an input screen for receiving display area information of a stereoscopic image partial screen on a screen of the display device, determining a recognized control mode and input information of the input screen, and determining a display control method according to the determined display control method; It includes a control unit 240 for controlling the driving of the first liquid crystal driver 220 and the second liquid crystal driver 230.

The input device (not shown) includes at least one of input devices such as a mouse, a keyboard, or a touch pad of a touch screen.

13 * 11 of the liquid crystal unit 210 is for clarity to explain the operation of the present invention, the present invention is not limited thereto.

The liquid crystal unit 210 includes a liquid crystal panel such as a TN-LCD, a STN-LCD, a TFT-MONO, and the size of the plurality of liquid crystal cells constituting the liquid crystal panel is the same size as the adjacent liquid crystal cell or a different size. It may be configured as.

In the present invention, a method of forming a barrier in the liquid crystal unit 210 may be divided into a method of forming a barrier in a vertical direction and a method of forming a barrier in a horizontal direction.

That is, the control method of forming a barrier in the vertical direction in the liquid crystal part 210 drives all or part of the odd-numbered segment terminals S1, S3, S5,... And the whole of the comon terminals C1 to C13. That's the way.

The control method of forming a horizontal barrier in the liquid crystal part 210 is a method of driving all or part of the odd-numbered comon terminals C1, C3, C5,..., And the entire segment terminals S1 to S11.

Therefore, when displaying the 2D image, the controller 240 controls driving of the first liquid crystal driver 220 and the second liquid crystal driver 230 so that a barrier pattern is not formed in the liquid crystal unit 210, and displays a stereoscopic image. In this case, the driving of the first and second liquid crystal drivers 220 and 230 is controlled to form a barrier pattern in the liquid crystal unit 210 according to the currently determined display control method.

Meanwhile, in the embodiment of the present invention, the operation of displaying the stereoscopic image partial screen on the screen of the display device (not shown) is performed in the same process as the signal flowchart of FIG. 6. Although the present invention can display both a stereoscopic image full screen and a stereoscopic image partial screen, an embodiment of the present invention will be mainly described with respect to the display of a stereoscopic image partial screen.

An embodiment of the present invention will be described in detail with reference to the signal flow chart of FIG. 6, in which the control unit 240 checks an input device (not shown) to determine whether a stereoscopic image mode is set. To judge.

Subsequently, if it is determined that the stereoscopic image partial screen mode is set after the stereoscopic image mode is set, the controller 240 displays a menu screen for setting the size and display position of the stereoscopic image partial screen on the screen of the display device (not shown). do.

In this case, the size of the stereoscopic image partial screen may be set in the input screen as shown in FIGS. 3 and 4, and the shape of the stereoscopic image partial screen may be set in the input screen as shown in FIG. 5.

3 and 4, the display position of the partial screen may be set after setting the size of the stereoscopic image partial screen. In this case, the display position of the partial screen may be fixed or variable. If the display position of the partial screen is changed, the coordinate value and the delay time for changing the display position of the partial screen are received and stored.

That is, the method of setting the display position of the three-dimensional image partial screen in the present invention will be described with reference to the signal flow diagram of FIG. 7. It is determined whether to fix to the position of the input coordinate value. For example, assuming that the recognized coordinate values for setting the size of the current stereoscopic image partial screen are (x1, y1), (x2, y2), (x3, y3), (x4, y4), the input coordinate values Then, the 3D image is displayed on the location of the coordinate value.

And, the display position of the three-dimensional image sub-screen can be set at random. When the three-dimensional image sub-screen is displayed, a coordinate value of the display position is generated using a predetermined random function to display the three-dimensional image sub-screen at the corresponding position.

In addition, unlike the above, when the user changes the display position of the three-dimensional image partial screen, the input screen may be provided so as to directly input the coordinate values of the variable position, in which case a delay before moving to each position. You can set the time.

Therefore, when the size and the display position information of the stereoscopic image partial screen is input in the above process, the controller 240 determines the display control method corresponding to the display area information of the input stereoscopic image partial screen, and determines the determined display control scheme. Accordingly, by controlling the first liquid crystal driver 220 and the second liquid crystal driver 230, a barrier pattern is formed in the liquid crystal unit 210 to correspond to the selected stereoscopic image partial screen in the liquid crystal unit 210.

Therefore, the stereoscopic image is displayed on the stereoscopic image partial screen set by the user on the screen of the display device (not shown).

The stereoscopic image partial screen may be implemented by overwriting the corresponding stereoscopic image data to a portion corresponding to the stereoscopic image among the 2D image data and outputting the overwritten image data to a display device (not shown). The stereoscopic image data may be implemented by generating left and right image data so that the left and right image data are overlapped and displayed on a display device (not shown).

Therefore, the image data for the stereoscopic image partial screen can be produced in various ways, and the present invention is not limited to a specific method for the implementation of the image data.

Meanwhile, in order to display the stereoscopic image partial screen on the screen of the display device (not shown), the controller 240 initially sets the stereoscopic image partial screen mode to be set on the input screen as shown in FIGS. 3 to 5. It will be recognized the display area of the, which will be described in detail as follows.

First, in the first method of setting the stereoscopic image sub-screen, when the stereoscopic image sub-screen mode is set, the control unit 240 may display x of the display area of the stereoscopic image sub-screen as shown in FIG. 3A on the screen of the display device (not shown). , y The input screen for inputting the coordinate value is displayed.

At this time, the user inputs the start point and the end point of the x, y coordinates of the area where the stereoscopic image partial screen is to be displayed on the input screen of FIG. 3a.

Accordingly, when a coordinate value for setting an area of a stereoscopic image partial screen is input as described above, the controller 240 calculates the input coordinate value and corresponds to the input value on a screen of a display device (not shown). The area is displayed as shown in FIG. 3B to allow the user to recognize the display area of the currently selected stereoscopic image subscreen. In this case, the display area of the selected stereoscopic image partial screen may change the color of the corresponding display area or display the corresponding area by a solid line or a dotted line to easily recognize the display area currently selected by the user.

Accordingly, when the user adjusts the display area by re-input of coordinate values, and inputs an input value for the display area and then inputs a confirmation key by using an input device (not shown), the controller 240 controls the display area. In this case, only the segment terminal and the comb terminal of the segment terminals S1 to S11 and the comb terminals C1 to C13 of the liquid crystal unit 210 corresponding to the stereoscopic image partial screen are calculated according to the calculation result. The first liquid crystal driver 220 and the second liquid crystal driver 230 are controlled to be driven.

In this case, when the barrier driven to correspond to the stereoscopic image partial screen set by the user is an even number, the controller 240 may operate the segment terminal (in the vertical direction stereoscopic image) or the come-on terminal (in the horizontal direction stereoscopic image). Adjust the number of) to be odd. Here, the number of segment terminals or comb-on terminals to be driven is preferably adjusted to be larger than the initial setting value, but it is also possible to adjust the reduction.

In addition, the second method of setting the display area of the three-dimensional image sub-screen is when the user selects an area to display the three-dimensional image by using an input device (not shown) such as a mouse or a keyboard after the three-dimensional image sub-screen mode is set The controller 240 recognizes the coordinates of the selected region and controls the first liquid crystal driver 220 and the second liquid crystal driver 230 so that only the barrier pattern corresponding to the selected region is formed in the liquid crystal unit 210. .

The second method will be described in detail with reference to FIG. 4. First, after the stereoscopic image partial screen mode is set, when a user drags a portion of the full screen to display the stereoscopic image partial screen as shown in FIG. 4, the controller ( In operation 240, a coordinate value of the dragged area is calculated and recognized.

At this time, the control unit 240 forms a barrier to display the stereoscopic image partial screen, and determines the segment terminal and the comon terminal corresponding to the barrier, and accordingly the first liquid crystal driver 220 and the second liquid crystal driver 230 It will control the driving.

When the number of segment terminals or comb terminals to be driven to display the stereoscopic image partial screen is determined to be an even number, the number is adjusted to an odd number. Also in the second method, the number of segment terminals or comb-on terminals can be adjusted to be more or less.

In addition, according to an exemplary embodiment of the present invention, a display form of a stereoscopic image partial screen may be set using an input screen as shown in FIG. 5, which displays an icon corresponding to a plurality of stereoscopic image partial screens when the stereoscopic image partial screen mode is set. The barrier pattern is formed on the liquid crystal unit 210 to be displayed on a screen of a device (not shown) and to display a stereoscopic image in the form of a stereoscopic image partial screen corresponding to an icon selected by the user.

At this time, the size and display position of the three-dimensional image sub-screen using a pre-stored value as a default value, or alternatively set the display format of the three-dimensional image sub-screen to the input screen as shown in Figure 5 and then display size and The display position can be arbitrarily set by the user on the input screen of FIG. 3 or 4.

Conversely, it is also possible to set the shape of the stereoscopic image partial screen on the input screen of FIG. 5 after setting the size of the stereoscopic image partial screen on the input screen of FIG. 3 or 4.

Meanwhile, when the 3D image partial screen is set in the same manner as the example of FIGS. 3 to 5, the controller 240 determines whether the number of barriers is an odd number by checking the barriers corresponding to the set 3D image partial screen. As a result, when the number of barriers is determined to be an even number rather than an odd number, the first liquid crystal driver 220 or the second liquid crystal driver 230 is controlled to have an odd number of barriers.

For example, the stereoscopic image partial screen is normally displayed by turning off the driving of an even number of barriers in the vertical direction corresponding to the stereoscopic image partial screen or by driving one more barrier. Here, when changing the number of driving of the barrier, the control unit 240 also adjusts the size of the stereoscopic image partial screen. In forming the barrier, the first and second liquid crystal drivers 220 and 230 are formed to form at least three barrier patterns.

In the practice of the present invention, a stereoscopic image sub-screen is set and an image desired by the user is displayed as a stereoscopic image on the set sub-screen, and the set partial screen information and the corresponding image data are stored so that the user re-creates the same information later. Without input, the corresponding stereoscopic image may be displayed only by the user's selection.

Meanwhile, the operation of displaying a stereoscopic image by forming a barrier in the vertical direction has been described above, but as described above, the barrier terminal can be formed in the horizontal direction by controlling the segment terminal and the comb-on terminal. Even when the user rotates 90 °), the user may display a stereoscopic image screen desired by the user.

In addition, the present invention can be immediately implemented by applying a display device such as TFT-LCD, organic EL, PDP, FED, etc. to display a stereoscopic image with a horizontal / vertical switching function.

Therefore, by designing the barrier to be switched in a horizontal / vertical direction rather than in one direction, it is possible to display not only a stereoscopic image displayed in a horizontal direction with respect to a screen of a display device (not shown), but also a stereoscopic image displayed in a vertical direction. It is possible.

On the other hand, the embodiments of the present invention described above are intended to explain those skilled in the art to fully understand and practice the present invention, those skilled in the art will recognize that the present invention is not limited to the scope of the above-described embodiments. Accordingly, those skilled in the art will recognize that various modifications to the embodiments of the present invention are possible, and that other embodiments are possible without departing from the spirit or scope of the present invention.
