Information processing apparatus, program, and information processing method
There is provided an information processing apparatus including a display control unit causing an image for a left eye and an image for a right eye to be displayed respectively to a left eye and a right eye of an observer, the image for a left eye and the image for a right eye showing a stereoscopic image, and interchanging, depending on an amount of change occurring at a time of change of display of the stereoscopic image, images to be displayed respectively to the left eye and the right eye of the observer.
1. An information processing apparatus comprising: a stereoscopic display control unit which separately controls an image displayed to a left eye and an image displayed to a right eye of an observer to display a stereoscopic image, and
wherein the stereoscopic display control unit interchanges the image displayed to the left eye and the image displayed to the right eye, depending on an amount of rotational change of the stereoscopic image;
wherein, when a rotation angle of the stereoscopic image is within a first range including (180×n)° (n is an odd number), the stereoscopic display control unit interchanges the images to be displayed respectively to the left eye and the right eye of the observer.
2. The information processing apparatus according to claim 1 ,
wherein, when the amount of rotational change indicates that a relative shift between the image displayed to the left eye and the image displayed to the right eye is reversed in a horizontal direction, the stereoscopic display control unit interchanges the images to be displayed respectively to the left eye and the right eye of the observer.
3. The information processing apparatus according to claim 1 ,
wherein the first range is ((180×n)±45°).
4. The information processing apparatus according to claim 1 ,
wherein the stereoscopic display control unit causes an interpolation image to be displayed at a time of interchanging the images to be displayed respectively to the left eye and the right eye of the observer.
5. The information processing apparatus according to claim 4 ,
wherein the interpolation image is generated by linear interpolation between the image for a left eye and the image for a right eye.
6. The information processing apparatus according to claim 5 ,
wherein the interpolation image is displayed for 250 ms.
7. The information processing apparatus according to claim 1 ,
wherein the stereoscopic display control unit causes a same image to be displayed to each of the left eye and the right eye of the observer, depending on the amount of change in rotation.
8. The information processing apparatus according to claim 7 ,
wherein, when the amount of rotational change indicates that a relative shift between the image for a left eye and the image for a right eye is larger in a vertical direction than in a horizontal direction, the stereoscopic display control unit causes the same image to be displayed to each of the left eye and the right eye of the observer.
9. The information processing apparatus according to claim 7 ,
wherein the same image is the image for a left eye or the image for a right eye.
10. The information processing apparatus according to claim 7 ,
wherein, when the rotation angle of the stereoscopic image is within a second range including (90×m)° (m is an odd number), the display control unit causes the same image to be displayed to each of the left eye and the right eye of the observer.
11. The information processing apparatus according to claim 10 ,
wherein the second range is ((90×m)±45°).
12. The information processing apparatus according to claim 7 ,
wherein the stereoscopic display control unit displays an interpolation image at a time of causing the same image to be displayed to each of the left eye and the right eye of the observer.
13. A non-transitory computer-readable medium having embodied thereon a program, which when executed by a processor causes the processor to perform a method, the method comprising:
separately controlling an image displayed to a left eye and an image displayed to a right eye of an observer to display a stereoscopic image; and
interchanging the image displayed to the left eye and the image displayed to the right eye, depending on an amount of rotational change of the stereoscopic image;
wherein, when a rotation angle of the stereoscopic image is within a first range
including (180×n)° (n is an odd number), the stereoscopic display control unit interchanges the images to be displayed respectively to the left eye and the right eye of the observer.
14. An information processing method comprising:
separately controlling an image displayed to a left eye and an image displayed to a right eye of an observer to display a stereoscopic image; and
interchanging the image displayed to the left eye and the image displayed to the right eye, depending on an amount of rotational change of the stereoscopic image;
wherein, when a rotation angle of the stereoscopic image is within a first range
including (180×n)° (n is an odd number), the stereoscopic display control unit interchanges the images to be displayed respectively to the left eye and the right eye of the observer.
15. The information processing apparatus of claim 1 , wherein the stereoscopic display control unit interchanges the image displayed to the left eye and the image displayed to the right eye to prevent an unnatural impression of the image to the observer due to the rotational change of the stereoscopic image.
