Description

  The present invention relates to a stereoscopic video display apparatus that displays stereoscopic video using binocular parallax and a parallax adjustment method thereof.

  In recent years, development of stereoscopic image display devices for viewing stereoscopic images using a plasma display panel or a liquid crystal panel has been actively conducted. For example, a stereoscopic video display device using binocular parallax periodically displays a right-eye video and a left-eye video having parallax on the screen.

  When the right-eye video is projected, this video is viewed with the right eye, and when the left-eye video is projected, this video is viewed with the left eye. Since the right-eye video and the left-eye video have parallax, the video looks three-dimensional. The stereoscopic image has a sense of depth and pop-out that changes depending on the amount of parallax between the right-eye video and the left-eye video. If the amount of parallax is large, the depth and pop-out will be large, and if the amount of parallax is small, the depth and pop-out will be small.

  In such a stereoscopic video display device, for example, shutter-type glasses are used to view the right-eye video with the right eye and the left-eye video with the left eye. In the shutter-type glasses, a liquid crystal filter that switches between passage and blocking of light is arranged in the right-eye lens and the left-eye lens. Switching between the passage and blocking of light is performed by opening and closing the shutter of the liquid crystal filter.

  Specifically, the shutter opening / closing timings of the liquid crystal filters disposed on the right-eye lens and the left-eye lens are switched in synchronization with the switching timing of the right-eye video and the left-eye video displayed on the display panel screen.

  That is, in synchronization with the timing of switching to the right-eye image, the shutter of the liquid crystal filter arranged on the right-eye lens is opened to allow light to pass, the shutter of the liquid crystal filter arranged on the left-eye lens is closed to block the light, and the right eye Only show the video for the right eye.

  Also, in synchronization with the timing of switching to the left-eye image, the shutter of the liquid crystal filter arranged on the left-eye lens is opened to allow light to pass, the shutter of the liquid crystal filter arranged on the right-eye lens is closed to block the light, and the left eye Just show the video for the left eye.

  At this time, the switching timing between the right-eye video and the left-eye video and the shutter opening / closing timing of the liquid crystal filter are synchronized by connecting the display panel and the glasses wirelessly or by wire.

  By repeating this alternately, the viewer can view a stereoscopic image from the right-eye video and the left-eye video. For example, Patent Document 1 and Patent Document 2 disclose a stereoscopic video display device using shutter-type glasses.

  Furthermore, in a stereoscopic video display device using shutter-type glasses, the parallax amount between the right-eye video and the left-eye video can be changed according to the position of the viewer viewing the stereoscopic video display device. It is disclosed in Document 4. Depending on the distance between the stereoscopic image display device and the viewer, the feeling of depth and the feeling of popping out change. For this reason, in Patent Document 3 and Patent Document 4, the right-eye video and the left-eye video are shifted from each other in the horizontal direction to adjust the amount of parallax. By adjusting the amount of parallax, the viewer can view a three-dimensional image in which the feeling of depth and the feeling of popping out are changed.

JP 2000-36939 A Japanese Patent Laid-Open No. 10-240212 JP 2004-349736 A Japanese Patent Laid-Open No. 2004-180069

  In the conventional stereoscopic video display device, a right-eye video and a left-eye video are displayed on the screen of the display panel, and a stereoscopic video can be viewed based on the right-eye video and the left-eye video. In addition, according to the position of the viewer who views the stereoscopic video display device, the amount of parallax of the stereoscopic video can be adjusted to adjust the feeling of depth and the feeling of popping out. However, since the adjustment of the parallax amount is performed by shifting the right-eye video and the left-eye video in the horizontal direction, the end of the stereoscopic video is lost by the amount of the shift.

  When viewing a three-dimensional video, the viewing position is important because the depth and pop-out of the three-dimensional video change depending on the position of the viewer. In particular, it is common for content production companies that provide three-dimensional video to set a viewing position for viewing a three-dimensional video in advance and produce a three-dimensional video that is optimal at that viewing position. Seem. For this reason, when viewing a stereoscopic video at a position different from the viewing position set by the content production company etc., it looks different from the intended stereoscopic video of the content production company etc. You may not be able to see it.

  For this reason, for example, as described above, if the parallax amount is adjusted by shifting the right-eye video and the left-eye video in the horizontal direction, the depth feeling of the optimal stereoscopic video intended by the content production company or the like You can get a feeling of popping out. However, the conventional configuration is not originally intended to comfortably view a stereoscopic video intended by a content production company or the like. In other words, it is possible to change the sense of depth and pop-out of a three-dimensional image, but when viewing a three-dimensional video content as a single work such as a movie, the end of the three-dimensional image is missing, It is not necessarily comfortable for the person.

  As described above, in the conventional configuration, when adjusting the amount of parallax according to the position of the viewer, there is a possibility that the end of the stereoscopic image is missing. When viewing a video content, it is not necessarily comfortable for the viewer.

  The present invention solves the above-mentioned problem, and when adjusting the amount of parallax according to the position of the viewer, it suppresses the occurrence of lack in the stereoscopic video with the adjusted amount of parallax and improves the comfort of the viewer It is an object of the present invention to provide a stereoscopic image display device and a parallax adjustment method thereof.

  In order to achieve the above object, a stereoscopic video display apparatus of the present invention includes a display panel having a screen on which video is displayed, and a video control unit that displays the video on the screen, and the videos have parallax with each other. A stereoscopic image display device that uses glasses to view the right-eye video and the left-eye video periodically displayed on the screen, including a right-eye video and a left-eye video, wherein the video control unit includes the video controller In the coordinate system of orthogonal X-axis, Y-axis, and Z-axis where the horizontal direction of the image is the X-axis direction, the vertical direction is the Y-axis direction, and the depth direction is the Z-axis direction, An adjustment unit configured to adjust a parallax amount between the right-eye image and the left-eye image based on a change, wherein the adjustment unit is configured for the right-eye image with respect to a reference position of the right-eye image or the left-eye image; Video or left eye video Area parts, or, a configuration to adjust the parallax amount by moving the partial area of the right eye image and the left-eye video.

  In order to achieve the above object, the method for adjusting the parallax amount of the stereoscopic image display apparatus of the present invention includes a display panel having a screen on which an image is displayed, and a video control unit that displays the image on the screen. The video includes a right-eye video and a left-eye video having parallax with each other, and the parallax amount adjustment of a stereoscopic video display device that uses glasses to periodically view the right-eye video and the left-eye video displayed on the screen In the X-axis, Y-axis, and Z-axis coordinate systems orthogonal to each other, wherein the horizontal direction of the image is the X-axis direction, the vertical direction is the Y-axis direction, and the depth direction is the Z-axis direction, On the basis of a change in the current coordinates with respect to the reference coordinates of the right-eye video or the left-eye video with respect to a reference position of the right-eye video or the left-eye video, or the right-eye video and For the left eye A method of adjusting the parallax amount by moving the partial area of the image.

  According to the stereoscopic image display device and the parallax adjustment method of the present invention, in the coordinate system of the X axis, the Y axis, and the Z axis orthogonal to each other, Since the adjustment unit that adjusts the parallax amount of the left-eye video image is provided, it is possible to change the sense of depth and pop-out of the three-dimensional video image according to the position of the viewer.

  That is, at the viewing position where the viewer can view a stereoscopic image in an optimal state, the position of the glasses worn by the viewer is set as the reference coordinates of the glasses, and the viewer is actually viewing the stereoscopic image. When the position of the glasses worn by the viewer at the viewing position is the current coordinates of the glasses, a change in the current coordinates with respect to the reference coordinates of the glasses can be calculated as a change amount. By adjusting the amount of parallax between the right-eye video and the left-eye video according to the amount of change in the current coordinates relative to the reference coordinates of the glasses, even if the viewer's position changes from the optimal viewing position, It is possible to change the feeling of depth and the feeling of popping out to an appropriate state.

  In particular, the adjustment unit moves a partial area of the right-eye video or the left-eye video or a partial area of the right-eye video and the left-eye video with respect to the reference position of the right-eye video or the left-eye video. Since the amount of parallax is adjusted, it is possible to suppress the occurrence of chipping at the ends of the right-eye video and the left-eye video. For example, the center of the right-eye image is set as the reference position of the right-eye image, and a part of the right-eye image is moved in the X-axis direction or the Z-axis rotation direction with respect to the reference position. And the entire area of the left-eye video are not changed. Accordingly, it is possible to adjust only the amount of parallax between a partial area of the right-eye video and a corresponding partial area of the left-eye video. That is, since it does not affect the edge area of the right-eye video or the left-eye video, the occurrence of chipping at the edge can be suppressed. As a result, even when a stereoscopic video content is viewed as one piece of a movie or the like, it is possible to suppress the occurrence of chipping at the end of the stereoscopic video and improve the comfort of the viewer.

FIG. 1 is a block diagram showing the relationship between shutter-type glasses and a stereoscopic video display device in one embodiment, FIG. 2 is a front view of a display panel when video is displayed on the stereoscopic video display device, and FIG. It is the schematic for demonstrating the image | video containing the image | video for images, and the image | video for left eyes.

<1. Relationship Between Glasses 100 and 3D Image Display Device 200>
First, the relationship between the shutter-type glasses 100 and the stereoscopic video display device 200 will be described. 1 and 2, the stereoscopic video display apparatus 200 includes a display panel 230 on which a screen 220 for displaying a video 210 is disposed, and a video control unit 240 that controls the display of the video 210. As the display panel 230, for example, a plasma display panel or a liquid crystal panel is used.

  As shown in FIG. 3, the image 210 includes a right-eye image 210R and a left-eye image 210L having parallax with each other. The video control unit 240 performs control so that the right-eye video 210R and the left-eye video 210L having parallax are alternately displayed on the screen 220 of the display panel 230. When the right-eye video 210R is projected, the right-eye video 210R is viewed with the right eye, and when the left-eye video 210L is projected, the left-eye video 210L is viewed with the left eye. Since the right-eye video 210R and the left-eye video 210L have parallax, the video 210 looks three-dimensional.

  In FIG. 3, the letter “A” is displayed in the right-eye video 210R and the left-eye video 210L. When the right-eye video 210R and the left-eye video 210L are alternately displayed on the screen 220 of the display panel 230, the viewer sees the video 210 having a parallax amount (W1). That is, the image 210 looks three-dimensional. In this stereoscopic image 210, the sense of depth and pop-out of the stereoscopic image 210 change depending on the amount of parallax (W1) between the right-eye image 210R and the left-eye image 210L. If the amount of parallax (W1) is large, the depth and pop-out will be large, and if the amount of parallax (W1) is small, the depth and pop-out will be small.

  In order to view the right eye image 210R with the right eye and the left eye image 210L with the left eye, for example, shutter-type glasses 100 are used. In the shutter-type glasses 100, a liquid crystal filter that switches between passage and blocking of light is disposed in the right-eye lens and the left-eye lens. Switching between the passage and blocking of light is performed by opening and closing the shutter of the liquid crystal filter.

  Specifically, the shutter opening / closing timings of the liquid crystal filters disposed on the right-eye lens and the left-eye lens are switched in synchronization with the switching timing of the right-eye image 210R and the left-eye image 210L displayed on the display panel 230.

  That is, in synchronization with the timing of switching to the right-eye image 210R, the shutter of the liquid crystal filter disposed on the right-eye lens is opened to allow light to pass, the shutter of the liquid crystal filter disposed on the left-eye lens is closed to block the light, The right eye image 210R is shown only to the right eye.

  Also, in synchronization with the timing of switching to the left-eye image 210L, the shutter of the liquid crystal filter disposed on the left-eye lens is opened to allow light to pass, and the shutter of the liquid crystal filter disposed on the right-eye lens is closed to block the light, The left eye image 210L is shown only to the left eye. The switching timing between the right-eye video 210R and the left-eye video 210L and the shutter opening / closing timing of the liquid crystal filter are synchronized by connecting the display panel 230 and the glasses 100 wirelessly or by wire.

  By continuing to open and close the shutter, the viewer periodically views the right-eye video 210R and the left-eye video 210L having parallax with the right eye and the left eye. As a result, the viewer can view the stereoscopic image 210 based on the right-eye image 210R and the left-eye image 210L that are periodically repeated.

<2. Change in current coordinates of eyeglasses 100 (Z-axis direction) and change in parallax amount>
Next, a change in the current coordinates (Z-axis direction) and a change in the amount of parallax with respect to the reference coordinates of the glasses 100 will be described. FIG. 4 is a correlation diagram illustrating changes in the current coordinates (Z-axis direction) with respect to the reference coordinates of the glasses 100 and changes in the amount of parallax.

  In FIG. 4, the horizontal direction of the image 210 is the X-axis direction, the vertical direction is the Y-axis direction, the depth direction is the Z-axis direction, and the X, Y, and Z axes are orthogonal to each other with the center of the image 210 as the origin. Let us consider a case where the eyeglasses 100 are moved in the Z-axis direction from the origin of the center of the image 210 in the coordinate system.

  In FIG. 4A, the coordinates of the glasses 100 whose distance in the Z-axis direction is L1a are set as the reference coordinates of the glasses 100. At this time, for example, the letter “A” displayed in the right-eye video 210R and the left-eye video 210L in FIG. 3 is viewed as a stereoscopic video 210 having a parallax amount (W1a).

  In FIG. 4B, the coordinates of the glasses 100 moved by L1b in the Z-axis direction are set as the current coordinates of the glasses 100. In this state, the viewer wearing the glasses 100 approaches the screen 220. At this time, the character “A” in FIG. 4B appears as a three-dimensional image 210 having a greater sense of depth and popping out than the character “A” in FIG. When it is desired not to change the sense of depth or popping out of the character “A” in FIG. 4A and the character “A” in FIG. 4B, the amount of parallax between the character “A” in FIG. W1b) may be made smaller than the parallax amount (W1a).

  In FIG. 4C, the coordinates of the glasses 100 moved by L1c in the Z-axis direction are set as the current coordinates of the glasses 100. This is a state in which the viewer wearing the glasses 100 has moved away from the screen 220. At this time, the letter “A” in FIG. 4C appears as a three-dimensional image 210 with a smaller sense of depth and popping out than the letter “A” in FIG. When it is desired not to change the sense of depth or popping out of the character “A” in FIG. 4A and the character “A” in FIG. 4C, the amount of parallax of the character “A” in FIG. W1c) may be larger than the parallax amount (W1a).

<2A. Adjustment of parallax amount with respect to change of current coordinates of eyeglasses 100 (Z-axis direction)>
Next, adjustment of the parallax amount with respect to a change in the current coordinates of the glasses 100 (Z-axis direction) will be described. FIG. 5 is a functional block diagram of the glasses 100 and the adjustment unit at the time of adjusting the parallax amount, and FIG. 6 is an explanatory diagram illustrating a state before and after the movement of the video block at the time of adjusting the parallax amount.

  As described with reference to FIG. 4, the three-dimensional image 210 has a different depth feeling and popping feeling depending on the position of the viewer viewing the screen 220. For this purpose, as shown in FIG. 5, the video control unit 240 includes an adjustment unit 250 that adjusts the amount of parallax between the right-eye video 210 </ b> R and the left-eye video 210 </ b> L. Based on the change of the current coordinates with respect to the reference coordinates of the glasses 100, the video control unit 240 adjusts the parallax amount between the right-eye video 210R and the left-eye video 210L by the adjustment unit 250, as shown in FIG. The adjustment unit 250 adjusts the amount of parallax by moving a partial region of the right-eye image 210R or the left-eye image 210L with respect to the reference position of the right-eye image 210R or the left-eye image 210L.

  Specifically, it is as follows.

  The glasses 100 are provided with a coordinate detection unit 110 that detects the current coordinates of the glasses 100. In FIG. 5, the coordinate detection unit 110 of the glasses 100 detects that the current coordinates of the glasses 100 have moved from the reference coordinates in the Z-axis direction. The current coordinates of the glasses 100 detected by the coordinate detection unit 110 are transmitted to the video control unit 240 via the transmission unit 120 disposed in the glasses 100. The transmitted current coordinates of the glasses 100 are received by the receiving unit 260 disposed in the adjusting unit 250 of the video control unit 240. Based on the current coordinates of the glasses 100 received by the receiving unit 260, the calculation unit 270 calculates the amount of change in the current coordinates with respect to the reference coordinates of the glasses 100.

  On the other hand, the adjustment unit 250 of the video control unit 240 causes the parallax vector detection unit 280 to detect a parallax vector in the video region 320 based on the right-eye video 210R and the left-eye video 210L. As shown in FIG. 6, the video area 320 is subdivided and divided into video blocks 290. A parallax vector in the video block 290 of the right-eye video 210R and the left-eye video 210L is detected, and a parallax amount in the right-eye video 210R and the left-eye video 210L is detected based on the parallax vector.

  Based on the calculation result of the calculation unit 270 and the detection result of the parallax vector detection unit 280 described above, the parallax vector processing unit 300 causes the parallax vector of the video block 290 to adjust the change of the current coordinates with respect to the reference coordinates of the glasses 100. Is processed. As shown in FIG. 6, the processing of the disparity vector is performed by moving the video block 290 with respect to the X-axis direction. Thereby, the parallax vector can be increased or decreased.

  At this time, an area where the video block 290 does not exist is generated due to the movement of the video block 290, and a part of the area for the right-eye video 210R or the left-eye video 210L is lost. The video block 290 is interpolated. Then, the interpolated right-eye video 210R and left-eye video 210L are displayed on the screen 220 as output video.

  For this interpolation, a general interpolation technique may be used. For example, the following may be used. That is, the interpolation of the area where the video block 290 generated in the right-eye video 210R does not exist may be performed based on the corresponding video block 290 of the left-eye video 210L. Alternatively, interpolation may be performed based on the video block 290 of the right-eye video 210R displayed before the right-eye video 210R displayed later or the video block 290 of the right-eye video 210R displayed later. The interpolation of the area where the video block 290 does not exist in the left-eye video 210L is the reverse of the above-described content.

  Note that the processing of the disparity vector by the disparity vector processing unit 300 may be automatically performed according to the calculation result calculated by the calculation unit 270, or the disparity adjustment amount input is performed under a situation that the viewer feels necessary. The viewer may manually perform the operation manually via the unit 330. The parallax adjustment amount input unit 330 may be any device capable of an external input operation.

<2B. Movement of video block 290 and change in parallax amount>
Next, a specific movement of the video block 290 and a change in the amount of parallax with respect to a change in the current coordinates of the glasses 100 (Z-axis direction) will be described.

  First, as shown in FIG. 6A, the video area 320 of the right-eye video 210R and the left-eye video 210L is divided into subdivided video blocks 290. In FIG. 6A, both the right-eye video 210R and the left-eye video 210L are divided into video blocks 290 subdivided into “1” to “35”.

  Next, as shown in FIG. 6B, the video blocks 290 of the right-eye video 210R and the left-eye video 210L are compared, and the positions of the video blocks 290 whose videos match are the same or different. And a disparity vector is detected. When the positions of the video blocks 290 with the same video are the same, the disparity vector is “0”, and when they are different, the disparity vectors according to the difference amount and the direction are included. In FIG. 6B, since the positions of the video blocks 290 of “A”, “B”, and “C” in the right-eye video 210R and the left-eye video 210L are different, the “A”, “B”, The “C” video blocks 290 have disparity vectors corresponding to the amount of difference and direction of each other. The amount of difference between the video blocks 290 of “A”, “B”, and “C” is the amount of parallax.

  Next, as shown in FIG. 6C, the video blocks 290 having the same video and different positions are moved. Either “A” of the right-eye video 210R or the left-eye video 210L is adjusted by an amount corresponding to the adjustment of the parallax vectors of the video blocks 290 of “A”, “B”, and “C” of the right-eye video 210R and the left-eye video 210L. , “B”, “C” video blocks 290 are moved. In FIG. 6C, the video blocks 290 of “A”, “B”, and “C” of the left-eye video 210L are moved. 6A, the video blocks 290 of “A”, “B”, and “C” corresponding to the video blocks 290 of “22”, “23”, and “30” of the left-eye video 210L are shown in FIG. As shown in c), they are moved to “23”, “24”, and “31”, respectively. Thereby, the parallax vectors of the video blocks 290 of “A”, “B”, and “C” of the right-eye video 210R and the left-eye video 210L are adjusted, and the parallax amount is also changed.

  As described above, when a part of the video block 290 in the video area 320 is moved, the amount of parallax in a part of the moved video area 320 is changed. That is, even when the sense of depth or pop-out changes depending on the position of the viewer, only a part of the areas having the parallax of the right-eye video 210R or the left-eye video 210L (the parallax of the video area 320) is canceled out. If some of the video blocks 290) are moved, the sense of depth and the sense of popping out will not change.

  FIG. 6 described above shows the amount of parallax when the viewer approaches the right-eye video 210R and the left-eye video 210L when the right-eye video 210R and the left-eye video 210L have the parallax shown in FIG. It explains the adjustment of. When the viewer approaches the right-eye video 210R and the left-eye video 210L, the sense of depth and the feeling of popping out increase. In this case, as shown in FIG. 6C, the amount of parallax between the right-eye video 210R and the left-eye video 210L may be reduced. This is because the sense of depth and popping that are increased by the viewer approaching the right-eye video 210R and the left-eye video 210L are offset. Note that when the viewer moves away from the right-eye video 210R and the left-eye video 210L, the feeling of depth and the feeling of popping out are reduced, so the amount of parallax between the right-eye video 210R and the left-eye video 210L may be increased.

  Further, when only a part of the region having the parallax of the right-eye video 210R or the left-eye video 210L (a part of the video block 290 having the parallax of the video region 320) is moved, a region where the video block 290 does not exist is generated. However, this region can be interpolated by using common interpolation techniques.

  By the adjustment described above, even if the position of the viewer changes, it is possible to keep the feeling of depth and the feeling of popping out from changing.

<3. Change in current coordinates of eyeglasses 100 (around Z axis) and change in parallax amount>
Next, a change in the current coordinates (around the Z axis) and a change in the amount of parallax with respect to the reference coordinates of the glasses 100 will be described. FIG. 7 is a correlation diagram showing changes in the current coordinates (around the Z axis) with respect to the reference coordinates of the glasses 100 and changes in the amount of parallax.

  In FIG. 7, the horizontal direction of the image 210 is the X-axis direction, the vertical direction is the Y-axis direction, the depth direction is the Z-axis direction, and the X, Y, and Z axes are orthogonal to each other with the center of the image 210 as the origin. Let us consider a case where the eyeglasses 100 are rotationally moved around the Z axis passing through the origin at the center of the image 210 (the rotation direction of the Z axis).

  In FIG. 7A, the coordinates of the glasses 100 with the angle around the Z axis being θ2a degrees are set as the reference coordinates of the glasses 100. This θ2a degree is a case where the angle is 0 degree. At this time, for example, the letter “A” displayed in the right-eye video 210R and the left-eye video 210L in FIG. 3 is viewed as a stereoscopic video 210 having a parallax amount (W2a).

  In FIG. 7B, the coordinates of the glasses 100 that have been rotated about the Z axis by θ2b degrees are the current coordinates of the glasses 100. In this state, the viewer wearing the glasses 100 tilts his / her face with respect to the screen 220. At this time, the letter “A” in FIG. 7B appears as a three-dimensional image 210 having a different feeling of depth and popping out than the letter “A” in FIG. When it is desired not to change the feeling of depth or popping out of the character “A” in FIG. 7A and the character “A” in FIG. 7B, the amount of parallax of the character “A” in FIG. The character “A” may be rotated by θ2b degrees while making W2b) the same as the parallax amount (W1a).

<3A. Adjustment of the amount of parallax with respect to changes in the current coordinates of the glasses 100 (around the Z axis)>
Next, adjustment of the amount of parallax with respect to a change in the current coordinates of the glasses 100 (around the Z axis) will be described. FIG. 8 is a functional block diagram of the glasses 100 and the adjustment unit 250 at the time of adjusting the parallax amount, and FIG. 9 is an explanatory diagram illustrating a state before and after the movement of the video block 290 at the time of adjusting the parallax amount.

  As described with reference to FIG. 7, the sense of depth and the sense of popping out of the stereoscopic image 210 differ depending on the position of the viewer viewing the screen 220. For this purpose, as shown in FIG. 8, the video control unit 240 includes an adjustment unit 250 that adjusts the parallax amount between the right-eye video 210R and the left-eye video 210L. Based on the change in the current coordinates with respect to the reference coordinates of the glasses 100, the video control unit 240 adjusts the parallax amount between the right-eye video 210R and the left-eye video 210L with the adjustment unit 250, as shown in FIG. The adjusting unit 250 adjusts the amount of parallax by rotating and moving a partial region of the right-eye image 210R or the left-eye image 210L with respect to the reference position of the right-eye image 210R or the left-eye image 210L.

  Specifically, it is as follows.

  The glasses 100 are provided with a coordinate detection unit 110 that detects the current coordinates of the glasses 100. In FIG. 8, the coordinate detection unit 110 of the glasses 100 detects that the current coordinates of the glasses 100 have been rotated around the Z axis from the reference coordinates. The current coordinates of the glasses 100 detected by the coordinate detection unit 110 are transmitted to the video control unit 240 via the transmission unit 120 disposed in the glasses 100. The transmitted current coordinates of the glasses 100 are received by the receiving unit 260 disposed in the adjusting unit 250 of the video control unit 240. Based on the current coordinates of the glasses 100 received by the receiving unit 260, the calculation unit 270 calculates the amount of change in the current coordinates with respect to the reference coordinates of the glasses 100.

  On the other hand, the adjustment unit 250 of the video control unit 240 causes the parallax vector detection unit 280 to detect a parallax vector in the video region 320 based on the right-eye video 210R and the left-eye video 210L. As shown in FIG. 9, the video area 320 is subdivided and divided into video blocks 290. A parallax vector in the video block 290 of the right-eye video 210R and the left-eye video 210L is detected, and a parallax amount in the right-eye video 210R and the left-eye video 210L is detected based on the parallax vector.

  Based on the calculation result of the calculation unit 270 and the detection result of the parallax vector detection unit 280 described above, the parallax vector processing unit 300 causes the parallax vector of the video block 290 to adjust the change of the current coordinates with respect to the reference coordinates of the glasses 100. Is processed. As shown in FIG. 9, the processing of the parallax vector is performed by rotating the video block 290 around the Z axis. Thereby, the parallax vector can be increased or decreased.

  At this time, an area where the video block 290 does not exist is generated due to the movement of the video block 290, and a part of the area for the right-eye video 210R or the left-eye video 210L is lost. The video block 290 is interpolated. Then, the interpolated right-eye video 210R and left-eye video 210L are displayed on the screen 220 as output video.

  For this interpolation, a general interpolation technique may be used. For example, the following may be used. That is, the interpolation of the area where the video block 290 generated in the right-eye video 210R does not exist may be performed based on the corresponding video block 290 of the left-eye video 210L. Alternatively, interpolation may be performed based on the video block 290 of the right-eye video 210R displayed before the right-eye video 210R displayed later or the video block 290 of the right-eye video 210R displayed later. The interpolation of the area where the video block 290 does not exist in the left-eye video 210L is the reverse of the above-described content.

  Note that the processing of the disparity vector by the disparity vector processing unit 300 may be automatically performed according to the calculation result calculated by the calculation unit 270, or the disparity adjustment amount input is performed under a situation that the viewer feels necessary. The viewer may manually perform the operation manually via the unit 330. The parallax adjustment amount input unit 330 may be any device capable of an external input operation.

<3B. Movement of video block 290 and change in parallax amount>
Next, a specific movement of the video block 290 and a change in the amount of parallax with respect to a change in the current coordinates of the glasses 100 (around the Z axis) will be described.

  First, as shown in FIG. 9A, the video area 320 of the right-eye video 210R and the left-eye video 210L is divided into subdivided video blocks 290. In FIG. 9A, both the right-eye video 210R and the left-eye video 210L are divided into video blocks 290 subdivided into “1” to “35”.

  Next, as shown in FIG. 9B, the video blocks 290 of the right-eye video 210R and the left-eye video 210L are compared, and the positions of the video blocks 290 that match the video are the same or different. And a disparity vector is detected. When the positions of the video blocks 290 with the same video are the same, the disparity vector is “0”, and when they are different, the disparity vectors according to the difference amount and the direction are included. In FIG. 9B, since the positions of the video blocks 290 of “A”, “B”, and “C” in the right-eye video 210R and the left-eye video 210L are different, the “A”, “B”, The “C” video blocks 290 have disparity vectors corresponding to the amount of difference and direction of each other. The amount of difference between the video blocks 290 of “A”, “B”, and “C” is the amount of parallax.

  Next, as shown in FIG. 9C, the video blocks 290 having the same video and different positions are moved. Either “A” of the right-eye video 210R or the left-eye video 210L is adjusted by an amount corresponding to the adjustment of the parallax vectors of the video blocks 290 of “A”, “B”, and “C” of the right-eye video 210R and the left-eye video 210L. , “B”, “C” video blocks 290 are moved. In FIG. 9C, the “A”, “B”, and “C” video blocks 290 of the right-eye video 210R and the “A”, “B”, and “C” video blocks 290 of the left-eye video 210L are moved. I am letting. In FIG. 9A, the video blocks 290 of “A”, “B”, and “C” corresponding to the video blocks 290 of “25”, “26”, and “33” of the video 210R for the right eye, and the video for the left eye As shown in FIG. 9C, the right-eye video blocks 290 corresponding to the video blocks 290 of “22”, “23”, and “30” of 210L are converted into video blocks 290 of “A”, “B”, and “C”. The image block 290 of “25”, “26”, and “33” of 210R is rotated and moved so that the difference amount does not change. As shown in FIG. 7, the rotation angle is θ2b degrees that is the angle at which the glasses 100 are inclined. Thereby, the parallax vectors of the video blocks 290 of “A”, “B”, and “C” of the right-eye video 210R and the left-eye video 210L are adjusted, and the parallax amount is also changed.

  As described above, when a part of the video block 290 in the video area 320 is moved, the amount of parallax in a part of the moved video area 320 is changed. That is, even when the sense of depth or pop-out changes depending on the position of the viewer, only a part of the areas having the parallax of the right-eye video 210R or the left-eye video 210L (the parallax of the video area 320) is canceled out. If some of the video blocks 290) are moved, the sense of depth and the sense of popping out will not change.

  In FIG. 9 described above, when the right-eye video 210R and the left-eye video 210L have the parallax shown in FIG. 9B, the viewer turns his neck to the right with respect to the right-eye video 210R and the left-eye video 210L. It explains the adjustment of the amount of parallax when tilted. When the viewer tilts his / her neck to the right, the feeling of depth and the feeling of popping out change according to the tilted angle. In this case, as shown in FIG. 9C, the amount of parallax may be adjusted by rotating the video block 290 of the left-eye video 210L in the same direction (right direction) as the direction in which the head is tilted. By doing so, the sense of depth or popping that has changed as the head is tilted is offset. When the viewer tilts his / her neck to the left with respect to the right-eye video 210R and the left-eye video 210L, similarly, the video block of the right-eye video 210R in the same direction (left direction) as the direction of tilting the neck. The parallax amount may be adjusted by rotating and moving 290. This is because the amount of parallax changed by tilting the head is offset.

  Further, when only a part of the region having the parallax of the right-eye video 210R or the left-eye video 210L (a part of the video block 290 having the parallax of the video region 320) is moved, a region where the video block 290 does not exist is generated. However, this region can be interpolated by using common interpolation techniques.

  By the adjustment described above, even if the position of the viewer changes, it is possible to keep the feeling of depth and the feeling of popping out from changing.

<4. Change in current coordinates (X-axis direction) of eyeglasses 100 and change in parallax amount>
Next, a change in the current coordinates (X-axis direction) and a change in the amount of parallax with respect to the reference coordinates of the glasses 100 will be described. FIG. 10 is a correlation diagram showing changes in the current coordinates (X-axis direction) with respect to the reference coordinates of the glasses 100 and changes in the amount of parallax.

  In FIG. 10, the horizontal direction of the image 210 is the X-axis direction, the vertical direction is the Y-axis direction, the depth direction is the Z-axis direction, and the X, Y, and Z axes are orthogonal to each other with the center of the image 210 as the origin. Let us consider a case where the eyeglasses 100 are moved in the X-axis direction from the Z-axis passing through the origin of the center of the image 210 in the coordinate system.

  In FIG. 10A, the coordinates of the glasses 100 with no movement in the X-axis direction and the angle formed by the Z-axis and the X-axis with the origin as the apex and θ3a degrees are set as the reference coordinates of the glasses 100. This angle θ3a is a case where the angle is 90 degrees. At this time, for example, when the letter “A” displayed in the right-eye video 210R and the left-eye video 210L in FIG. 3 is located at the end of the screen 220, the stereoscopic video 210 having the parallax amount (W3a) is obtained. Will see. Since the parallax amount (W3a) at the right end portion of the screen 220 and the parallax amount (W3a) at the left end portion are the same, the sense of depth and pop-out at the right end portion of the stereoscopic image 210 is the depth at the left end portion. It is the same as feeling and popping out.

  In FIG. 10B, the current coordinates of the glasses 100 are the coordinates of the glasses 100 that are moved in the X-axis direction and the angle formed by the Z-axis and the X-axis with the origin as the apex is θ3b. This is a state in which a viewer wearing glasses 100 has moved laterally from the center of the screen 220. At this time, the letter “A” at the right end in FIG. 10B is a three-dimensional image 210 having a greater sense of depth and popping than the letter “A” at the right end in FIG. appear. Also, the letter “A” at the left end in FIG. 10B appears as a three-dimensional image 210 with less sense of depth and popping out than the letter “A” at the left end in FIG. . When it is desired not to change the sense of depth or pop-out between the character “A” in FIG. 10A and the character “A” in FIG. 10B, the character “A” at the right end in FIG. The parallax amount (W3bR) of the character “A” at the left end in FIG. 10B is larger than the parallax amount (W3a). do it.

<4A. Adjustment of the amount of parallax with respect to a change in the current coordinates of the glasses 100 (X-axis direction)>
Next, adjustment of the amount of parallax with respect to a change in the current coordinates of the glasses 100 (X-axis direction) will be described. FIG. 11 is a functional block diagram of the glasses 100 and the adjustment unit 250 at the time of adjusting the parallax amount, and FIG. 12 is an explanatory diagram illustrating a state before and after the movement of the video block 290 at the time of adjusting the parallax amount.

  As described with reference to FIG. 10, the sense of depth and the sense of popping out of the stereoscopic image 210 differ depending on the position of the viewer viewing the screen 220. For this purpose, as shown in FIG. 11, the video control unit 240 includes an adjustment unit 250 that adjusts the amount of parallax between the right-eye video 210 </ b> R and the left-eye video 210 </ b> L. Based on the change of the current coordinates with respect to the reference coordinates of the glasses 100, the video control unit 240 adjusts the parallax amount between the right-eye video 210R and the left-eye video 210L by the adjustment unit 250, as shown in FIG. The adjustment unit 250 adjusts the amount of parallax by moving a partial region of the right-eye image 210R or the left-eye image 210L with respect to the reference position of the right-eye image 210R or the left-eye image 210L.

  Specifically, it is as follows.

  The glasses 100 are provided with a coordinate detection unit 110 that detects the current coordinates of the glasses 100. In FIG. 11, the coordinate detection unit 110 of the glasses 100 detects that the current coordinates of the glasses 100 have moved from the reference coordinates in the X-axis direction. The current coordinates of the glasses 100 detected by the coordinate detection unit 110 are transmitted to the video control unit 240 via the transmission unit 120 disposed in the glasses 100. The transmitted current coordinates of the glasses 100 are received by the receiving unit 260 disposed in the adjusting unit 250 of the video control unit 240. Based on the current coordinates of the glasses 100 received by the receiving unit 260, the calculation unit 270 calculates the amount of change in the current coordinates with respect to the reference coordinates of the glasses 100.

  On the other hand, the adjustment unit 250 of the video control unit 240 causes the parallax vector detection unit 280 to detect a parallax vector in the video region 320 based on the right-eye video 210R and the left-eye video 210L. As shown in FIG. 12, the video area 320 is subdivided and divided into video blocks 290. A parallax vector in the video block 290 of the right-eye video 210R and the left-eye video 210L is detected, and a parallax amount in the right-eye video 210R and the left-eye video 210L is detected based on the parallax vector.

  Based on the calculation result of the calculation unit 270 and the detection result of the parallax vector detection unit 280 described above, the parallax vector processing unit 300 causes the parallax vector of the video block 290 to adjust the change of the current coordinates with respect to the reference coordinates of the glasses 100. Is processed. As shown in FIG. 12, the processing of the parallax vector is performed by moving the video block 290 in the X-axis direction. Thereby, the parallax vector can be increased or decreased.

  At this time, an area where the video block 290 does not exist is generated due to the movement of the video block 290, and a part of the area for the right-eye video 210R or the left-eye video 210L is lost. The video block 290 is interpolated. Then, the interpolated right-eye video 210R and left-eye video 210L are displayed on the screen 220 as output video.

  For this interpolation, a general interpolation technique may be used. For example, the following may be used. That is, the interpolation of the area where the video block 290 generated in the right-eye video 210R does not exist may be performed based on the corresponding video block 290 of the left-eye video 210L. Alternatively, interpolation may be performed based on the video block 290 of the right-eye video 210R displayed before the right-eye video 210R displayed later or the video block 290 of the right-eye video 210R displayed later. The interpolation of the area where the video block 290 does not exist in the left-eye video 210L is the reverse of the above-described content.

  Note that the processing of the disparity vector by the disparity vector processing unit 300 may be automatically performed according to the calculation result calculated by the calculation unit 270, or the disparity adjustment amount input is performed under a situation that the viewer feels necessary. The viewer may manually perform the operation manually via the unit 330. The parallax adjustment amount input unit 330 may be any device capable of an external input operation.

<4B. For movement of video block 290 and change in parallax amount>
Next, a specific movement of the video block 290 and a change in the amount of parallax with respect to a change in the current coordinates of the glasses 100 (X-axis direction) will be described.

  First, as shown in FIG. 12A, the video area 320 of the right-eye video 210R and the left-eye video 210L is divided into subdivided video blocks 290. In FIG. 12A, both the right-eye video 210R and the left-eye video 210L are divided into video blocks 290 divided into “1” to “35”.

  Next, as shown in FIG. 12B, the video blocks 290 of the right-eye video 210R and the left-eye video 210L are compared, and the positions of the video blocks 290 that match the video are the same or different. And a disparity vector is detected. When the positions of the video blocks 290 with the same video are the same, the disparity vector is “0”, and when they are different, the disparity vectors according to the difference amount and the direction are included. In FIG. 12B, the positions of the video blocks 290 of “A”, “B”, “C”, “D”, “E”, and “F” in the right-eye video 210R and the left-eye video 210L are different. Therefore, the video blocks 290 of “A”, “B”, “C”, “D”, “E”, and “F” have disparity vectors corresponding to different amounts and directions. The amount of difference between the video blocks 290 of “A”, “B”, “C”, “D”, “E”, and “F” is the amount of parallax.

  Next, as shown in FIG. 12C, the video blocks 290 having the same video and different positions are moved. The right-eye video 210R is adjusted by an amount corresponding to the adjustment of the parallax vectors of the video blocks 290 of “A”, “B”, “C”, “D”, “E”, and “F” of the right-eye video 210R and the left-eye video 210L. And the video block 290 of “A”, “B”, “C”, “D”, “E”, “F” of any of the left-eye video 210L is moved. In FIG. 12C, the video blocks 290 of “A”, “B”, “C”, “D”, “E”, “F” of the left-eye video 210L are moved.

  In FIG. 12A, the video blocks 290 of “A”, “B”, and “C” corresponding to the video blocks 290 of “9”, “10”, and “17” of the left-eye video 210L are shown in FIG. As shown in c), they are moved to “8”, “9”, and “16”, respectively. Thereby, the parallax vectors of the video blocks 290 of “A”, “B”, and “C” of the right-eye video 210R and the left-eye video 210L are adjusted, and the parallax amount is also changed. In particular, in this case, since the parallax vector of the video block 290 is increased, the amount of parallax is also increased.

  Also, in FIG. 12A, video blocks 290 of “D”, “E”, and “F” corresponding to video blocks 290 of “27”, “28”, and “35” of the video 210L for the left eye are illustrated. As shown in FIG. 12 (c), they are moved to “26”, “27”, and “34”, respectively. Accordingly, the parallax vectors of the video blocks 290 of “D”, “E”, and “F” of the right-eye video 210R and the left-eye video 210L are adjusted, and the parallax amount is also changed. In particular, in this case, since the parallax vector of the video block 290 is small, the amount of parallax is also small.

  As described above, when a part of the video block 290 in the video area 320 is moved, the amount of parallax in a part of the moved video area 320 is changed. That is, even when the sense of depth or pop-out changes depending on the position of the viewer, only a part of the areas having the parallax of the right-eye video 210R or the left-eye video 210L (the parallax of the video area 320) is canceled out. If some of the video blocks 290) are moved, the sense of depth and the sense of popping out will not change.

  In FIG. 12 described above, when the right-eye video 210R and the left-eye video 210L have the parallax shown in FIG. 12B, the viewer moves to the right with respect to the right-eye video 210R and the left-eye video 210L. It explains the adjustment of the amount of parallax at the time. When the viewer moves to the right side, the depth and depth at the right end increase and the depth and depth at the left end decrease. In this case, as shown in FIG. 12C, the right end parallax amount of the right eye video 210R and the left eye video 210L may be reduced and the left end parallax amount may be increased. This is because the sense of depth and pop-up at the right end that has increased by moving to the right side cancels out the sense of depth and pop-out at the left end that has become smaller. When the viewer moves to the left, the depth and pop-out feeling at the right end are reduced, and the depth and pop-out feeling at the left end are increased, so the parallax amount at the right end is increased and the parallax amount at the left end is reduced. do it.

  Further, when only a part of the region having the parallax of the right-eye video 210R or the left-eye video 210L (a part of the video block 290 having the parallax of the video region 320) is moved, a region where the video block 290 does not exist is generated. However, this region can be interpolated by using common interpolation techniques.

  By the adjustment described above, even if the position of the viewer changes, it is possible to keep the feeling of depth and the feeling of popping out from changing.

<Summary of one embodiment>
According to the above configuration, the amount of parallax between the right-eye image 210R and the left-eye image 210L is adjusted based on the change in the current coordinates relative to the reference coordinates of the glasses 100 in the mutually orthogonal X-axis, Y-axis, and Z-axis coordinate systems. Since the adjusting unit 250 is provided, it is possible to change the sense of depth and the sense of popping out of the stereoscopic image 210 according to the position of the viewer.

  That is, in the viewing position where the viewer can view the stereoscopic image 210 in an optimal state, when the position of the glasses 100 worn by the viewer is set as the reference coordinates of the glasses 100, the viewer is actually stereoscopic. If the position of the glasses 100 worn by the viewer is the current coordinates of the glasses 100 at the viewing position where the video 210 is viewed, the change in the current coordinates with respect to the reference coordinates of the glasses 100 can be calculated as the amount of change. By adjusting the amount of parallax between the right-eye image 210R and the left-eye image 210L in accordance with the change amount of the current coordinates with respect to the reference coordinates of the glasses 100, even if the viewer's position changes from the optimal viewing position, the three-dimensional It is possible to change the depth feeling and the pop-out feeling of the correct image 210 to an appropriate state.

  In particular, the adjustment unit 250 may include a partial region having a parallax of the right-eye image 210R or the left-eye image 210L with respect to the reference position of the right-eye image 210R or the left-eye image 210L, or the right-eye image 210R and the left-eye image. Since the amount of parallax is adjusted by moving a part of the image 210L, it is possible to suppress the occurrence of chipping at the ends of the right-eye image 210R and the left-eye image 210L.

  For example, the center of the right eye image 210R is set as the reference position of the right eye image 210R, and a part of the region having the parallax of the right eye image 210R is moved in the X axis direction or the Z axis rotation direction with respect to the reference position. The other areas of the right-eye video 210R and the entire area of the left-eye video 210L are not changed. Thus, it is possible to adjust only the amount of parallax between the partial area having the parallax of the right-eye video 210R and the corresponding partial area having the parallax of the left-eye video 210L. That is, since it does not affect the end region of the right-eye image 210R or the left-eye image 210L, the occurrence of chipping at the end portion can be suppressed.

  As a result, even when viewing the content of the stereoscopic video 210 as one piece of a movie or the like, it is possible to suppress the occurrence of chipping at the end of the stereoscopic video 210 and improve the comfort of the viewer.

  In addition, when the change in the current coordinates with respect to the reference coordinates of the glasses 100 is a change in the distance in the Z-axis direction, a partial region having a parallax of the right-eye video 210R or the left-eye video 210L, or the right-eye video 210R and If the amount of parallax is adjusted by moving a part of the left-eye image 210L in the X-axis direction, even if the viewer's position changes from the optimal viewing position, the stereoscopic image 210 has a sense of depth and pop-out. Can be changed to an appropriate state.

  Further, when the change in the current coordinates with respect to the reference coordinates of the glasses 100 is an angle change in the rotation direction of the Z axis (around the Z axis), a partial region having a parallax of the right eye image 210R or the left eye image 210L; Alternatively, if the amount of parallax is adjusted by moving some areas of the right-eye video 210R and the left-eye video 210L in the rotation direction of the Z axis, even if the viewer's position changes from the optimal viewing position, the three-dimensional It is possible to change the depth feeling and the pop-out feeling of the correct image 210 to an appropriate state.

  In addition, when the change in the current coordinates with respect to the reference coordinates of the glasses 100 is a change in the distance from the Z axis to the X axis, a partial region having a parallax of the right eye image 210R or the left eye image 210L, or the right eye image The partial area of the video 210R and the left-eye video 210L is moved in the X-axis direction so that the amount of parallax is small, and the partial area having the parallax of the right-eye video 210R or the left-eye video 210L, or the right-eye video If the amount of parallax is adjusted by moving some areas of the 210R and the left-eye video 210L in the X-axis direction so that the amount of parallax is large, even if the viewer's position changes from the optimal viewing position, It is possible to change the depth feeling and the pop-out feeling of the correct image 210 to an appropriate state.

  In the embodiment of the present invention, when the current coordinates of the glasses 100 change in the Z-axis direction with respect to the reference coordinates, change around the Z-axis, and change in the X-axis direction, Although the amount of parallax was adjusted individually, if the current coordinates of the glasses 100 change in a complex manner in the Z-axis direction, around the Z-axis, and the X-axis direction with respect to the reference coordinates, the parallax is combined. The amount may be adjusted.

  Further, when adjusting the parallax amount between the right-eye video 210R and the left-eye video 210L, the adjustment may be performed by moving only a part of the right-eye video 210R, or a part of the left-eye video 210L. The adjustment may be made by moving only the region, or by moving both the partial region of the right-eye video 210R and the partial region of the left-eye video 210L.

  In addition, the adjustment unit 250 arranged in the stereoscopic video display device 200 may be partly or wholly arranged in the glasses 100.
