Description

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

The present invention relates to a stereoscopic image display technology, and more particularly, to a stereoscopic image display method and apparatus for displaying a 2D image and a stereoscopic image 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, while the conventional parallax-barrier stereoscopic image display device is based on a TFT-LCD display method, 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 three portions, 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. There is a case that there is no, and the thickness and spacing of the barrier is 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. It is impossible to watch stereoscopic images.

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.

Further, in the embodiment of the present invention, the operation of displaying the stereoscopic image full screen or 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. 8.

An embodiment of the present invention will be described in detail with reference to the signal flow chart of FIG. 8. During the initial or operation of the stereoscopic image display apparatus, the controller 240 checks the input apparatus (not shown) to determine whether the stereoscopic image mode is set. To judge.

Subsequently, when it is determined that the stereoscopic image mode is set, the controller 240 displays a menu screen for selecting a stereoscopic image full screen mode or a stereoscopic image partial screen mode on a screen of a display device (not shown).

Accordingly, when the stereoscopic image full screen mode is set, the controller 240 forms segment terminals S1, S3, S5, and the like corresponding to the vertical liquid crystal cell columns of the liquid crystal unit 210 to form a vertical barrier pattern. And the first liquid crystal driver 220 and the second liquid crystal unit 230 to drive the comb terminals C1 to C13 corresponding to the horizontal liquid crystal cell columns of the liquid crystal unit 210.

Therefore, when the left and right images are displayed on the screen of the display device (not shown), the left and right images are separated by the barrier pattern formed on the liquid crystal unit 210 to display a 3D image.

When the stereoscopic image partial screen mode is set, the 3D image partial screen as shown in FIGS. 3A to 3D can be displayed and operated. The 3D image partial screen as shown in FIGS. 3A to 3D is selected by the user and is controlled. The 240 determines a display control method corresponding to the selected stereoscopic image partial screen and controls the first liquid crystal driver 220 and the second liquid crystal driver 230 according to the determined display control method to the liquid crystal unit 210. A barrier pattern is formed in the liquid crystal unit 210 to correspond to the selected stereoscopic image partial screen.

Accordingly, a stereoscopic image is displayed on the display area of the selected stereoscopic image sub-screen and a 2D image is displayed on the screen of the display device (not shown) except for the display area of the selected partial screen.

In the above-described stereoscopic image partial screen, the stereoscopic image data is over-written on a portion corresponding to the stereoscopic image among the 2D image data, and the overlaid image data is output to the display device (not shown). Can be.

The stereoscopic image data of the stereoscopic image partial screen may be implemented as left and right image data so that the left and right image data are overlapped and displayed on a display device (not shown).

Accordingly, the image data for the stereoscopic image partial screen may be produced in various ways, and the present invention is not limited to the specific image data method.

On the other hand, in the embodiment of the present invention will be described in more detail the operation for setting the three-dimensional image screen.

First, when the stereoscopic image partial screen mode of FIG. 3A is set, the controller 240 displays the 2D image in the first area 311 and simultaneously displays the stereoscopic image in the second area 312. 220 and the second liquid crystal driver 230 are driven. On the contrary, it is also possible to form a barrier pattern such that the first region 311 is a stereoscopic image and the second region 312 is a 2D image.

In addition, when the stereoscopic image partial screen mode of FIG. 3B is set, the entire screen of the display device (not shown) is divided left and right by an area selected by the user so that a 2D image is displayed on the first area 321 and the second screen is displayed. The driving of the first and second liquid crystal drivers 220 and 230 is controlled to display a stereoscopic image in the region 322. That is, the cell column of the liquid crystal unit 210 corresponding to the first region 321 is not driven, but only the odd cell column among the cell columns of the liquid crystal unit 210 corresponding to the second region 322 is driven. .

In addition, when the stereoscopic image partial screen mode of FIG. 3C is set, the screen of the display device (not shown) is divided up and down by an area selected by the user, and a 2D image is displayed on the first area 331 and the second area is displayed. The driving of the liquid crystal unit 210 is controlled to display a stereoscopic image in the region 332. In addition, since it is possible to display the stereoscopic image partial screen as shown in FIG. 3c, it is possible to display the stereoscopic image partial screen as shown in FIG. 3d in the same manner.

Meanwhile, in order to display the stereoscopic image partial screen as shown in FIG. 3, the controller 240 recognizes the display area of the stereoscopic image partial screen set in the same manner as in FIGS. 4 to 6. This 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 controller 240 may display x of the display area of the stereoscopic image sub-screen as shown in FIG. 4A 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. 4a. Here, when the start point and the end point of the x and y coordinates corresponding to the display area of the stereoscopic image sub-screen are input, the range of the stereoscopic image sub-screen corresponding to the same is shown in FIG. 4B.

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 region is displayed as shown in FIG. 4C to allow the user to recognize the display region 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, although the number of segment terminals or comb-on terminals to be driven is preferably adjusted to be larger than the initial setting value, it is also possible to reduce and adjust in consideration of the display range of the 2D image.

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. 5. 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. 5, 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, in setting the display area of the stereoscopic image partial screen as shown in FIG. 5, the size of the display area may be arbitrarily set by the user.

The third method of setting the display area of the stereoscopic image sub-screen is to display icons corresponding to a plurality of stereoscopic sub-screens on a screen of a display device (not shown) when the stereoscopic image sub-screen mode is set. A barrier pattern is formed in the liquid crystal unit 210 such that a stereoscopic image is displayed on a stereoscopic image partial screen corresponding to a selected icon among the plurality of icons.

In the third method, it is possible to adjust the range in which the stereoscopic image is displayed after the currently set stereoscopic image sub-screen is displayed, which defaults to the coordinate value of the display area of the stereoscopic image sub-screen corresponding to the currently selected icon. This is because it is stored in advance, and the display area corresponding thereto may be different from the size desired by the user.

The method of FIG. 3 is described in detail with reference to FIG. 6 as follows.

First, when the stereoscopic image partial screen mode is set, the controller 240 displays icons corresponding to a plurality of stereoscopic image partial screens previously stored on the screen as shown in FIG. 6A.

Accordingly, the user selects one of the icons corresponding to the stereoscopic image partial screen, and the controller 240 drives the first liquid crystal driver 220 and the second liquid crystal driver 230 to correspond to the selected icon. The stereoscopic image partial screen selected by the user is displayed on the device (not shown).

In this case, when the 3D image partial screen is displayed on the display screen, the user may adjust the display area of the partial screen using a mouse or a key. For example, when adjusting the size of the display area using a mouse, as shown in FIG. 6B, the size of the partial screen can be adjusted by placing the cursor on the line 621 or 622 and moving the cursor to the range of the partial screen to be adjusted. have.

Meanwhile, when the stereoscopic image partial screen is set and the size of the partial screen is adjusted in the same manner as the example of FIGS. 4 to 6, the controller 240 examines the barrier corresponding to the adjusted stereoscopic image partial screen to determine the number of barriers. Is determined to be an odd number, and if it is determined that the number of barriers is 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, when an even number of vertical barriers corresponding to the stereoscopic image partial screen are activated as shown in FIG. 7, the stereoscopic image partial screen is turned off by turning off the barrier 710 or activating the barrier 720 indicated by a dotted line. Allow the display to display normally. When the driving of the barrier 710 is turned off, the controller 240 also adjusts the size of the 3D image partial screen. In addition, in forming the barrier, the first and second liquid crystal drivers 220 and 230 are controlled to form at least three barrier patterns.

In the embodiment of the present invention, as shown in the signal flow diagram of Fig. 9, after designating an arbitrary three-dimensional image sub-screen as described above, the display area data (for example, X, y coordinate data of the area corresponding to the partial screen).

Thereafter, when the corresponding stereoscopic image sub-screen is selected, it indicates that the display area data of the previously designated sub-screen is present. The area data is used to display the corresponding stereoscopic image sub-screen desired by the user.

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.
