It is determined as

The video control unit 120 controls the video rotation unit 130, the video output unit 140, and the synchronization signal generation unit 150. Specifically, the video control unit 120 outputs the sides determined by the determination unit 110 to the video rotation unit 130 to rotate the video, and gives a video output instruction to the video output unit 140.

Also, the video control unit 120 causes the synchronization signal generation unit 150 to generate a synchronization signal, and controls the opening and closing of the left eye shutter and the right eye shutter of each shutter glasses worn by a plurality of observers. That is, the video control unit 120 controls the opening and closing of the left-eye shutter and the right-eye shutter for the glasses 20 worn by the observer A and the glasses 30 worn by the observer B.

More specifically, when the video for the left eye for the observer at the observation position corresponding to the side determined by the determination unit 110 is displayed on the display screen 600, the video control unit 120 observes at the observation position. Open the left eye shutter of the shutter glasses worn by the person, close the right eye shutter of the shutter eyeglasses worn by the observer at the observation position, and attach an observer other than the observer at the observation position.

The video input / output unit 131 inputs, as input videos, a left-eye video that is a left-eye video and a right-eye video that is a right-eye video for viewing a stereoscopic video. Then, the video input / output unit 131 stores the input left-eye video and right-eye video in the memory 133.

Then, the rotation control unit 132 reads the left-eye image and the right-eye image from the memory 133, and rotates the left-eye image and the right-eye image as the rotated image. Eye images are generated. Then, the rotation control unit 132 stores the generated rotation left eye image and rotation right eye image in the memory 133.

Then, the video input / output unit 131 reads the rotated left-eye video and the rotated right-eye video from the memory 133, and outputs them to the video output unit 140.

Note that the video rotation unit 130 does not include the rotation control unit 132, and when the video input / output unit 131 reads the video from the memory 133, the left-eye video and the right-eye video are rotated. The video and the rotating right eye video may be read out and output to the video output unit 140.

3, the video output unit 140 outputs the rotated video generated by the video rotation unit 130. In other words, the video output unit 140 converts the rotated left-eye video and the rotated right-eye video generated by the video rotating unit 130 into a left-eye video and a right-eye video for the observer at regular time intervals. By alternately outputting, the images are alternately displayed on the display screen 600 at the predetermined time interval.

Next, video processing performed by the video processing apparatus 10 will be described in detail.

FIG. 5 is a flowchart for explaining video processing performed by the video processing apparatus 10 according to Embodiment 1 of the present invention.

As shown in the figure, first, the determination unit 110 determines the side of the display screen 600 that is closest to the observation position of the observer (S102). A detailed description of the process in which the determination unit 110 determines the sides of the display screen 600 will be described later.

Then, the image rotation unit 130 generates a rotation image obtained by rotating the input image so that the side determined by the determination unit 110 is the bottom side (S104). A detailed description of the process in which the video rotation unit 130 generates a rotated video will be described later.

Then, the video output unit 140 outputs the rotated video generated by the video rotating unit 130 (S106). A detailed description of the process in which the video output unit 140 outputs the rotated video will be described later.

Next, details of the process (S102 in FIG. 5) in which the determination unit 110 determines the sides of the display screen 600 will be described.

FIG. 6 is a flowchart for explaining processing in which the determination unit 110 according to Embodiment 1 of the present invention determines the sides of the display screen 600.

FIG. 7 is a diagram for explaining a process in which the determination unit 110 according to Embodiment 1 of the present invention determines the sides of the display screen 600.

First, as shown in FIG. 6, the sensor detects a signal emitted by a device used by an observer (S202). Specifically, as illustrated in FIG. 7, the 3D glass sensor L <b> 111 detects the glasses 20, and the 3D glass sensor R <b> 112 detects the glasses 30.

And as shown in FIG. 6, the discrimination | determination part 110 discriminate | determines the edge of the display screen 600 nearest to the detected sensor (S204).

Specifically, as illustrated in FIG. 7, the determination unit 110 detects a signal generated by the transmitter 21 of the glasses 20 when the 3D glass sensor L111 detects a signal generated by the transmitter 21 of the glasses 20 or a signal generated by the transmitter 21 of the glasses 20. If the detection is stronger than that, the side v1-v2 that is the side of the display screen 600 closest to the 3D glass sensor L111 that has detected the glasses 20 is determined as the side of the display screen 600 that is closest to the observation position of the observer A. .

In addition, when the 3D glass sensor R112 detects a signal emitted from the transmitter 21 of the glasses 30 or when the signal emitted from the transmitter 31 of the glasses 30 is detected more strongly than the 3D glass sensor L111, the determination unit 110 detects the glasses 30. The side v3-v4 that is the side of the display screen 600 that is closest to the 3D glass sensor R112 that has detected is determined as the side of the display screen 600 that is closest to the observation position of the viewer B.

Thus, the process of determining the sides of the display screen 600 by the determination unit 110 (S102 in FIG. 5) ends.

Next, details of the process (S104 in FIG. 5) in which the video rotation unit 130 generates a rotated video will be described.

FIG. 8 is a flowchart for explaining a process in which the video rotation unit 130 according to Embodiment 1 of the present invention generates a rotated video.

FIG. 9 to FIG. 13B are diagrams for explaining processing for generating a rotated image by the image rotation unit 130 according to Embodiment 1 of the present invention.

First, as shown in FIG. 8, the video input / output unit 131 of the video rotation unit 130 inputs a left-eye video and a right-eye video as input video (S302).

9 to 11C are diagrams for explaining an input video input by the video input / output unit 131 according to Embodiment 1 of the present invention.

As shown in FIG. 9, a camera AL51 that captures an image for the left eye of the observer A, a camera AR52 that captures an image for the right eye of the observer A, and an image for the left eye of the observer B are captured. The object 40 is imaged by the camera BL53 that performs this operation and the camera BR54 that captures an image for the right eye of the observer B.

As a result, the image shown in FIG. 10A is captured as the image for the left eye of the observer A, and the image shown in FIG. 10B is captured as the image for the right eye of the observer A. With these images, the observer A can observe a stereoscopic image as shown in FIG. 10C.

11A is captured as an image for the left eye of the observer B, and an image illustrated in FIG. 11B is captured as an image for the right eye of the observer B. With these images, the observer B can observe a stereoscopic image as shown in FIG. 11C.

Returning to FIG. 8, the rotation control unit 132 of the video rotation unit 130 acquires the side determined by the determination unit 110 from the video control unit 120 as a processing target side, and determines whether there is an unprocessed side (S304). ). When the rotation control unit 132 determines that there is an unprocessed side (Yes in S304), the rotation control unit 132 selects one of the unprocessed sides (S306).

Then, the rotation control unit 132 determines the rotation angle of the selected unprocessed side (S308). When the rotation control unit 132 determines that the rotation angle of the selected unprocessed side is “zero rotation angle” (“rotation angle zero” in S308), the rotation control unit 132 determines again whether there is an unprocessed side. (S304).

When the rotation control unit 132 determines that the rotation angle of the selected unprocessed side is “rotation angle 180 degrees” (“rotation angle 180 degrees” in S308), the rotation control unit 132 rotates the input image by 180 degrees (S310). It is determined again whether there is an unprocessed side (S304).

FIGS. 12A to 13B are diagrams for explaining processing in which the rotation control unit 132 according to the first embodiment of the present invention rotates the input video.

As shown in FIGS. 11A and 11B, the input video for the observer B is displayed on the display screen 600 so that the sides v1-v2 are the bottom sides. However, as shown in FIG. 7, the observer B observes from the opposite side of the observer A.

For this reason, as shown in FIG. 12A, it is necessary to rotate the image for the left eye of the viewer B by 180 degrees and display it on the display screen 600 so that the sides v3-v4 are the bottom sides. Similarly, as shown in FIG. 12B, it is necessary to rotate the image for the right eye of the viewer B by 180 degrees and display it on the display screen 600 so that the sides v3-v4 are the bottom sides.

Therefore, as shown in FIG. 13A, the rotation control unit 132 rotates the video as shown in FIG. 13B by changing the pixel value of each pixel in the video to a value when the video is rotated 180 degrees. Can be made.

Specifically, the rotation control unit 132 converts the pixel value of the pixel at the coordinates (x, y) to the position of the coordinates (hx, vy). Here, x and y are the horizontal and vertical positions of the pixels, respectively, and h and v are the numbers of pixels in the horizontal and vertical directions, respectively.

Returning to FIG. 8, as described above, the rotation control unit 132 repeats the above processing until it is determined that there is no unprocessed side. When it is determined that there is no unprocessed side (No in S304), the process ends. To do.

Thus, the process (S104 in FIG. 5) in which the video rotation unit 130 generates the rotated video ends.

Next, details of the process (S106 in FIG. 5) in which the video output unit 140 outputs the rotated video will be described.

FIG. 14 is a flowchart for explaining processing in which the video output unit 140 according to Embodiment 1 of the present invention outputs a rotated video.

FIG. 15 is a diagram for explaining processing in which the video output unit 140 according to Embodiment 1 of the present invention outputs a rotated video.

First, as illustrated in FIG. 14, when the video control unit 120 causes the video output unit 140 to output a left-eye video and display it on the display screen 600 (Yes in S <b> 402), the viewer's shutter for the video is displayed. The shutter for the left eye of the glasses is opened, and the shutter for the left eye and the right eye of the shutter glasses of another observer are closed (S404).

For example, as shown in FIG. 15A, when an image for the left eye of the observer A is displayed on the display screen 600, the image control unit 120 displays the shutter for the left eye of the eyeglass 20 of the observer A. And the shutters for the left eye and right eye of the eyeglasses 30 of the observer B are closed. Further, as shown in FIG. 15B, when an image for the left eye of the viewer B is displayed on the display screen 600, the video control unit 120 displays the shutter for the left eye of the glasses 20 of the viewer B. And the shutters for the left eye and right eye of the eyeglasses 30 of the observer A are closed.

Returning to FIG. 14, when the video control unit 120 causes the video output unit 140 to output the right-eye video and display it on the display screen 600 (No in S402, Yes in S406), the viewer of the video is observed. The right eye shutter of the shutter glasses is opened, and the left eye shutter and the right eye shutter of the shutter glasses of other observers are closed (S408).

For example, as shown in FIG. 15C, when an image for the right eye of the observer A is displayed on the display screen 600, the image control unit 120 displays the shutter for the right eye of the eyeglass 20 of the observer A. And the shutters for the left eye and right eye of the eyeglasses 30 of the observer B are closed. In addition, as shown in FIG. 15D, when an image for the right eye of the observer B is displayed on the display screen 600, the image control unit 120 displays the shutter for the right eye of the eyeglass 20 of the observer B. And the shutters for the left eye and right eye of the eyeglasses 30 of the observer A are closed.

As described above, the video output unit 140 alternately outputs the left-eye video and the right-eye video for the viewer A and the viewer B at regular time intervals in accordance with the instruction of the video control unit 120.

As described above, according to the video processing device 10 according to the first embodiment of the present invention, the side of the display screen 600 closest to the observation position of the observer is determined, and the input is performed so that the determined side becomes the bottom side. A rotation image obtained by rotating the image is generated, and the generated rotation image is output, so that the rotation image is displayed on the display screen 600. Thereby, an image is displayed on the display screen 600 such that the side of the display screen 600 closest to the observer is the bottom side. For this reason, it is possible to observe in the original direction to be observed regardless of the observation direction.

In addition, the video processing apparatus 10 includes a sensor that detects a signal generated by a device used by the observer, and when the sensor detects the signal, the side of the display screen 600 that is closest to the sensor is the bottom side. Then, a rotated image obtained by rotating the input image is generated. Here, since the device is a device used by the observer, it is considered that the observer is observing near the sensor that has detected the device. For this reason, the image is displayed on the display screen 600 so that the side of the display screen 600 closest to the sensor is the bottom side, so that the observer can observe the image in the original observation direction. .

Further, the video processing apparatus 10 inputs a left-eye video and a right-eye video for viewing a stereoscopic video, and a rotated left-eye video obtained by rotating the left-eye video and the right-eye video. Generate and output a rotating right-eye video. As a result, a stereoscopic image can be observed in the original direction to be observed regardless of the viewing direction.

In addition, the video output unit 140 alternately displays the rotated left-eye video and the rotated right-eye video at regular time intervals, thereby causing the display screen 600 to alternately display the regular left-eye video and the rotated right-eye video at regular time intervals. Accordingly, by viewing the left-eye video and the right-eye video alternately using the stereoscopic video viewing glasses, it is possible to observe the stereoscopic video in the original direction to be observed.

In addition, the determination unit 110 determines the side of the display screen 600 that is closest to the position of the stereoscopic video viewing glasses worn by the observer, and rotates the input video so that the side becomes the bottom side. Generate video. Here, since the eyeglasses are worn by the observer, the position of the eyeglasses becomes the observation position of the observer. For this reason, the video is displayed on the display screen 600 so that the side of the display screen 600 closest to the glasses is the base, so that the observer can observe the video in the original observation direction. .

Further, the eyeglasses are shutter eyeglasses, and the video processing device 10 opens the left eye shutter of the observer's shutter glasses when the video for the left eye of the observer close to the determined side is displayed. The eye shutter is closed and the left eye shutter and the right eye shutter of the shutter glasses of an observer other than the observer are closed. The video processing device 10 opens the right-eye shutter of the observer's shutter glasses and closes the left-eye shutter when an image for the right eye of the observer close to the determined side is displayed. The left eye shutter and the right eye shutter of the shutter glasses of the observer other than the observer are closed. Thus, by viewing the left-eye video and the right-eye video alternately using the shutter glasses for stereoscopic video viewing, it is possible to observe the stereoscopic video in the original observation direction. .

In addition, the video processing apparatus 10 includes a rectangular display screen 600. As a result, regardless of the direction of observation on the rectangular display screen 600, a stereoscopic image can be observed in the original direction to be observed.

In addition, the video processing apparatus 10 includes a rectangular display screen 600, and includes sensors for detecting glasses near any two of the four sides of the display screen 600, and the sensors detect the glasses. In this case, a rotation image is generated by rotating the input image so that the side of the display screen 600 closest to the sensor that has detected the glasses is the bottom side. Here, since the observer wears the glasses, if the glasses are arranged and detected near the two sides, the position of the glasses becomes the observation position of the observer. For this reason, by displaying the video on the display screen 600 such that the side of the display screen 600 closest to the glasses is the bottom side of the two sides, the observer can observe the original direction of the video. Can be observed.

In addition, the video processing apparatus 10 rotates the input video for the observer at one of the observation positions corresponding to two opposite sides of the four sides of the display screen 600 by 180 degrees to generate a rotated video. To do. That is, if two observers face each other across the display screen 600, the image observed by the two observers is upside down. For this reason, by rotating the input image for one of the observers by 180 degrees, both of the two observers can observe the original image to be observed.

In addition, the video processing apparatus 10 acquires a video signal, decodes the acquired video signal, outputs a video, and displays the video on the display screen 600. Thus, the video processing apparatus 10 can be realized as a system such as a mobile information terminal (tablet terminal) that acquires a video signal, processes it, and displays it.

The video input / output unit 131 reads the letterboxed video from the memory 133 and outputs it to the video output unit 140.

Note that the video rotation unit 130 does not include the rotation control unit 132 and the video processing unit 134, and rotates the left-eye video and the right-eye video when the video input / output unit 131 reads the video from the memory 133. The video whose size has been adjusted may be read out and output to the video output unit 140.

Next, details of the process (S104 in FIG. 5) in which the video rotation unit 130a generates a rotated video will be described.

FIG. 19 is a flowchart for explaining a process in which the video rotation unit 130a according to Embodiment 2 of the present invention generates a rotated video.

FIG. 20 is a diagram for explaining processing in which the video rotation unit 130a according to Embodiment 2 of the present invention generates a rotated video.

First, as shown in FIG. 19, the video input / output unit 131 of the video rotation unit 130a inputs an input video (S302), and the rotation control unit 132 determines whether there is an unprocessed side (S304). If it is determined that there is an unprocessed side (Yes in S304), one of the unprocessed sides is selected (S306). Since these processes (S302 to S306) are the same as the processes (S302 to S306) in the first embodiment, detailed description thereof is omitted.

Then, the rotation control unit 132 determines the rotation angle of the selected unprocessed side (S312). When the rotation control unit 132 determines that the rotation angle of the selected unprocessed side is “zero rotation angle” (“rotation angle zero” in S312), the rotation control unit 132 determines again whether there is an unprocessed side. (S304).

In addition, when the rotation control unit 132 determines that the rotation angle of the selected unprocessed side is “rotation angle left 90 degrees” (“rotation angle left 90 degrees” in S312), the rotation control unit 132 sets the input image to 90 leftward. (S314).

Then, the image processing unit 134 adjusts the size of the input image rotated 90 degrees leftward to the size of the display screen 600 by letterboxing (S316), and again determines whether there is an unprocessed side. Judgment is made (S304).

Specifically, as shown in FIG. 20, the video in FIG. 20A is rotated 90 degrees counterclockwise to generate the video in FIG. 20B, and the video in FIG. The letter box is generated to generate the image shown in FIG.

If the rotation control unit 132 determines that the rotation angle of the selected unprocessed side is “rotation angle right 90 degrees” (“rotation angle right 90 degrees” in S312), the rotation control unit 132 sets the input image to the right 90. (S318).

Then, the video processing unit 134 adjusts the size of the input video rotated 90 degrees rightward to the size of the display screen 600 by letterboxing (S320), and again determines whether there is an unprocessed side. Judgment is made (S304).

When the rotation control unit 132 determines that the rotation angle of the selected unprocessed side is “rotation angle 180 degrees” (“rotation angle 180 degrees” in S312), the rotation control unit 132 rotates the input image by 180 degrees (S322). It is determined again whether there is an unprocessed side (S304).

In this way, the rotation control unit 132 repeats the above process until it is determined that there is no unprocessed side. When it is determined that there is no unprocessed side (No in S304), the process is terminated.

Thus, the process (S104 in FIG. 5) in which the video rotation unit 130a generates the rotated video ends.

FIG. 21 is a diagram for explaining processing in which the video output unit 140 according to Embodiment 2 of the present invention outputs video.

As shown in the figure, the video output unit 140 sequentially outputs the left-eye video 1 that is the left-eye video of the viewers A, B, C, and D, and then the viewers A, B, and C And the right eye image 1 which is the right eye image of D and D are sequentially output. The video output unit 140 then sequentially outputs the left-eye video 2 that is the left-eye video of the viewers A, B, C, and D, and then the viewers A, B, C, and D The right-eye video 2 that is the right-eye video is sequentially output.

Depending on the display speed on the display screen 600, the video output unit 140 outputs the left-eye video 3 or the left-eye video after the right-eye video 1 instead of the left-eye video 2. You may decide to do it.

As described above, according to the video processing device 10a according to the second embodiment of the present invention, the rectangular display screen 600 and the sensors for detecting glasses are provided near the four sides of the display screen 600, and the glasses are detected. If the side of the display screen 600 closest to the sensor is the first of the four sides, the observer's input image at the observation position near the first side is rotated 180 degrees, and the side is the second side. In this case, the input image for the observer at the observation position near the second side is rotated 90 degrees to the left, and when the side is the third side, the input for the observer at the observation position near the third side is performed. The image is rotated 90 degrees to the right to generate a rotated image. In other words, when each of the four observers is observing from the four sides of the display screen 600, the video for one other person is 180 degrees, 90 degrees left, and 90 degrees right. It is necessary to rotate it. Therefore, by rotating the input image for the observer to 180 degrees, 90 degrees to the left, and 90 degrees to the right, all three observers can observe the original image in the direction to be observed.

Also, the video processing apparatus 10a adjusts the size of the input video rotated 90 degrees to the size of the display screen 600, and generates a rotated video. That is, when the display screen 600 is rectangular, when the video is rotated 90 degrees, the rotated video has a size different from the size of the display screen 600. For this reason, by adjusting the image after rotation to the size of the display screen 600, the observer can observe the image.

Also, the video processing apparatus 10a performs letterboxing that reduces the size of the input video rotated 90 degrees so that the entire video is displayed on the display screen 600. In other words, the viewer can observe the entire video by adjusting the size of the video that has been rotated to a size different from the size of the display screen 600 by letterboxing.

(Modification of Embodiment 2)
Next, a modification of the second embodiment of the present invention will be described. In the second embodiment, the observer observes from each of the four sides of the display screen 600. However, in the modification of the second embodiment, the observer observes from each of any three sides of the four sides of the display screen 600.

That is, the video processing apparatus according to this modification includes sensors for detecting glasses at positions corresponding to any three of the four sides that form the outer periphery of the display screen 600.

When the side determined by the determination unit 110 is the first side of the three sides, the video rotation unit rotates the input video for the observer at the observation position corresponding to the first side by 180 degrees, and the determination unit When the determined side is the second side of the three sides, the input video for the observer at the observation position corresponding to the second side is rotated by 90 degrees to generate a rotated video.

As described above, according to the video processing device according to the modification of the second embodiment of the present invention, when each of the three observers is observing from the three sides of the display screen 600, it is for the observer. By rotating the input image by 180 degrees and 90 degrees, all three observers can observe the original image in the direction to be observed.

The video processing apparatus 10b includes a controller sensor L111a and a controller sensor R112a instead of the 3D glass sensor L111 and the 3D glass sensor R112 of the video processing apparatus 10 in the first embodiment, but the other configurations are the same as those in the above embodiment. Since it is the same as that of form 1, detailed description is abbreviate | omitted.

Here, the controller 80 is a control device used by the observer A to control the video processing device 10b, and includes a transmitter 81 and an operation button 82. The controller 90 is a control device used by the observer B to control the video processing device 10b, and includes a transmitter 91 and operation buttons 92.

FIG. 24 is a diagram illustrating a process in which the video processing apparatus 10b according to the third embodiment of the present invention displays a video on the display screen 600.

First, when the sensor detects a signal generated by the controller, the determination unit 110 determines the side of the display screen 600 closest to the detected sensor as the side of the display screen 600 closest to the observation position. For example, when the controller sensor L111a detects a signal generated by the controller 80, the determination unit 110 determines the side of the display screen 600 that is closest to the controller sensor L111a.

Then, the image rotation unit 130 generates a rotation image obtained by rotating the input image so that the side determined by the determination unit 110 becomes the bottom side as an image for the observer using the controller. For example, when the controller sensor L111a detects a signal emitted from the controller 80, the video rotation unit 130 rotates the input video shown in (a1) of FIG. The rotated image shown in (b1) of FIG. Note that the image for the viewer B shown in (a2) of the figure is not rotated and is directly input to the video output unit 140 as the video shown in (b2) of the same figure.

Then, the video output unit 140 synthesizes the video shown in (b1) of the figure and the video shown in (b2) of the figure, and generates a synthesized video shown in (c) of the figure.

By displaying this composite image on the display screen 600, the optical lens 11 allows the observer A to observe the image shown in (d1) of the figure, and the observer B observes the image shown in (d2) of the figure. it can.

As described above, the video processing device 10b according to the third embodiment of the present invention includes the display screen 600 and the optical lens 11, and the optical lens 11 is divided into a plurality of areas of the display screen 600 for display. The synthesized image is refracted from one side of the display screen 600 so that one of the plurality of images before division is observed. That is, by using a lenticular lens as the optical lens 11, one image can be observed from one side of the display screen 600, so that the image is observed in the original observation direction regardless of the observation direction. can do.

In addition, the display screen 600 is rectangular, and the optical lens 11 refracts an image so that one image of a plurality of images can be observed from each of two opposite sides of the four sides of the display screen 600. Let For this reason, when an observer observes from the direction of the two sides, the image can be observed in the original direction to be observed.

In addition, the video processing apparatus 10b includes a sensor that detects a signal generated by a controller used by the observer, and rotates the input video so that the side of the display screen 600 closest to the sensor that has detected the controller is the bottom side. Generate rotating images. Here, since the said controller is an apparatus which an observer uses, it is thought that the observer is observing near the sensor which detected the said controller. For this reason, the image is displayed on the display screen 600 so that the side of the display screen 600 closest to the sensor is the bottom side, so that the observer can observe the image in the original observation direction. .

The rotated image shown in (b1) of FIG. Similarly, the image rotation unit 130 generates a rotation image shown in (b2) of the figure by rotating the input image shown in (a2) of the figure by 180 degrees as an image for the left eye of the observer A. To do.

Here, since the controller sensor B113a and the controller sensor T114a have the same functions as the controller sensor L111a or the controller sensor R112a, detailed description thereof is omitted.

The controller 93 is a controller used by the observer C, and the controller 94 is a controller used by the observer D. Here, since the controller 93 and the controller 94 have the same functions as the controller 80 or the controller 90, detailed description thereof is omitted.

Further, the video processing device 10d includes the same optical lens as the optical lens 12 of the video processing device 10c in the first modification of the third embodiment. In other words, the optical lens 12 is a lenticular sheet that refracts an image so that one image of the plurality of images is observed from each of the four sides forming the outer peripheral edge of the display screen 600.

Further, the determination unit 110 determines the side of the display screen 600 closest to the observer detected by the person recognition unit 170 as the side of the display screen 600 closest to the observer's observation position.

In addition, the image rotation unit 130 generates a rotation image obtained by rotating the input image so that the side determined by the determination unit 110 becomes the bottom as the image for the observer detected by the person recognition unit 170.

Next, details of the process (S102 in FIG. 5) in which the stereoscopic video reproduction unit 100b determines the side of the display screen 600 will be described.

FIG. 29 is a flowchart for explaining processing in which the stereoscopic video reproduction unit 100b according to Embodiment 4 of the present invention discriminates the sides of the display screen 600.

30 and 31 are diagrams for explaining processing in which the stereoscopic video reproduction unit 100b according to Embodiment 4 of the present invention determines the sides of the display screen 600.

First, as shown in FIG. 29, the camera 160 captures an image (S502). Specifically, as shown in FIG. 30, for example, a camera 160 is disposed in the vicinity of the side v2-v3 of the video processing apparatus 10e, and the camera 160 captures an image including the observer A and the observer B. . Here, it is assumed that the observer A is observing from the side v1-v2 and the observer B is observing from the side v3-v4. An image taken by the camera 160 is shown in FIG.

In the figure, the person recognizing unit 170 recognizes the observer C shown in the adjacent side v1-v4 region.

Then, the determination unit 110 determines the side of the display screen 600 closest to the observer detected by the person recognition unit 170 as the side of the display screen 600 closest to the observation position of the observer (S614). That is, the determination unit 110 determines the side v1-v2 as the side of the display screen 600 closest to the observation position of the observer A, and sets the side v3-v4 as the side of the display screen 600 closest to the observation position of the observer B. The side v1-v4 is determined as the side of the display screen 600 closest to the observation position of the observer C, and the side v2-v3 is determined as the side of the display screen 600 closest to the observation position of the observer D.

Each processing unit included in the integrated circuit may be individually made into one chip, or may be made into one chip so as to include a part or all of them. The name used here is LSI, but it may also be called IC, system LSI, super LSI, or ultra LSI depending on the degree of integration.

Further, the method of circuit integration is not limited to LSI, and implementation with a dedicated circuit or a general-purpose processor is also possible. An FPGA (Field Programmable Gate Array) that can be programmed after manufacturing the LSI, or a reconfigurable processor that can reconfigure the connection and setting of circuit cells inside the LSI may be used.

Furthermore, if integrated circuit technology that replaces LSI emerges as a result of advances in semiconductor technology or other derived technology, it is naturally also possible to integrate functional blocks using this technology. There is a possibility of adaptation of biotechnology.

The present invention can be applied to an image processing apparatus such as a tablet terminal that can observe an image in an original direction to be observed regardless of the direction of observation.
