Abstract

A display capable of performing optimum stereoscopic display according to a view position is provided. A display includes: a display section including a plurality of first pixels to a plurality of nth pixels, where n is an integer of 4 or more, and displaying a plurality of perspective images assigned to the first to nth pixels; a detection section detecting a view position of a viewer; and a display control section varying the number of the plurality of perspective images assigned to the first to nth pixels and varying a correspondence relationship between the first to nth pixels and the perspective images, according to the view position of the viewer.

Claims

1. A display comprising:

a display section including a plurality of first pixels to a plurality of nth pixels, where n is an integer of 4 or more, and displaying a plurality of perspective images assigned to the first to nth pixels;

a detection section detecting a view position of a viewer; and

a display control section varying the number of the plurality of perspective images assigned to the first to nth pixels and varying a correspondence relationship between the first to nth pixels and the perspective images, according to the view position of the viewer, wherein

the plurality of perspective images are a right-eye image and a left-eye image,

when the view position of the viewer is located at a first distance from the display section, the display control section performs display control to partition the display section into a plurality of sub-regions and performs display control on pixels in each of the sub-regions, independently, thereby to vary the correspondence relationship between the first to nth pixels and the perspective images for each of the sub-regions,

each of the sub-regions includes first pixels to nth pixels,

the display control section assigns the right-eye image to two adjacent pixels of the first pixel to the nth pixel and assigns the left-eye image to other two adjacent pixels of the first pixel to the nth pixel, in each of the sub-regions,

a combination of the two adjacent pixels to which the right-eye image is assigned in one sub-region is different from that in another sub-region, and a combination of the other two adjacent pixels to which the left-eye image is assigned in one sub-region is different from that in another sub-regions,

when the view position of the viewer is located at the first distance,

the display control section assigns the right-eye image to the first and second pixels and assigns the left-eye image to the third and fourth pixels, in a first sub-region, and the display control section assigns the right-eye image to the second and third pixels and assigns the left-eye image to the first and fourth pixels, in a second sub-region adjacent to the first sub-region, and

the display control section performs display control to allow luminance of the first pixel and the third pixel to be lower than that of the second pixel when a boundary portion between the first sub-region and the second sub-region is viewed from a right-eye position, and to allow luminance of the first pixel and the third pixel to be lower than that of the fourth pixel when the boundary portion is viewed from a left-eye position.

2. The display according to claim 1, wherein

the display control section moves positions in a horizontal direction of the respective sub-regions in response to movement in a horizontal direction of the view position of the viewer.

3. The display according to claim 1, wherein

the width of each of the sub-regions is equal to a pupillary distance.

4. The display according to claim 1, further comprising:

a separation section separating light beams from the first to nth pixels to allow the separated light beams to reach first to nth light-convergence regions located at a second distance from the display section, respectively,

wherein when the view position of the viewer is located at the second distance, the display control section assigns first to nth perspective images as the plurality of perspective images to the first to nth pixels in an entire screen of the display section.

5. The display according to claim 4, wherein

the width of each of the first to nth light-convergence regions is equal to a pupillary distance.

6. The display according to claim 4, wherein

the first distance is equal to a half of the second distance.

7. The display according to claim 4, wherein

when the view position of the viewer is located at the first distance, a right-eye image is assigned to pixels that correspond to the first to nth light-convergence regions and are viewable from a right-eye position, and a left-eye image is assigned to pixels that correspond to the first to nth light-convergence regions and are viewable from a left-eye position.

8. A display comprising:

a display section including a plurality of first pixels to a plurality of nth pixels, where n is an integer of 4 or more, and displaying a plurality of perspective images assigned to the first to nth pixels;

a detection section detecting a view position of a viewer; and

a display control section varying the number of the plurality of perspective images assigned to the first to nth pixels and varying a correspondence relationship between the first to nth pixels and the perspective images, according to the view position of the viewer, wherein

the plurality of perspective images are a right-eye image and a left-eye image, and

when the view position of the viewer is located at a first distance from the display section,

the display control section performs display control to partition the display section into a plurality of sub-regions and performs display control on pixels in each of the sub-regions, independently, thereby to vary the correspondence relationship between the first to nth pixels and the perspective images for each of the sub-regions,

the display control section assigns the right-eye image to the first and second pixels and assigns the left-eye image to the third and fourth pixels, in a first sub-region, and the display control section assigns the right-eye image to the second and third pixels and assigns the left-eye image to the first and fourth pixels, in a second sub-region adjacent to the first sub-region, and

the display control section performs display control to allow luminance of the first pixel and the third pixel to be lower than that of the second pixel when a boundary portion between the first sub-region and the second sub-region is viewed from a right-eye position, and to allow luminance of the first pixel and the third pixel to be lower than that of the fourth pixel when the boundary portion is viewed from a left-eye position.

9. A display comprising:

a display section including a plurality of first pixels to a plurality of nth pixels, where n is an integer of 4 or more, and displaying a plurality of perspective images assigned to the first to nth pixels;

a detection section detecting a view position of a viewer; and

a display control section varying the number of the plurality of perspective images assigned to the first to nth pixels and varying a correspondence relationship between the first to nth pixels and the perspective images, according to the view position of the viewer, wherein

the plurality of perspective images are a right-eye image and a left-eye image, when the view position of the viewer is located at a first distance from the display section,

the display control section performs display control to partition the display section into a plurality of sub-regions and performs display control on pixels in each of the sub-regions, independently, thereby to vary the correspondence relationship between the first to nth pixels and the perspective images for each of the sub-regions,

the display control section assigns a right-eye image to pixels that correspond to the first to nth light-convergence regions and are viewable from a right-eye position, and assigns a left-eye image to pixels that correspond to the first to nth light-convergence regions and are viewable from a left-eye position, and

the display control section performs display control to allow luminance of pixels of both adjacent sides of a pixel corresponding to a boundary portion between the light-convergence region viewable from a right-eye position and the light-convergence region viewable from a left-eye position to be lower than that of the pixel corresponding to the boundary portion when the boundary portion is viewed from a right-eye position, and to allow luminance of pixels of both adjacent sides a pixel corresponding to the boundary portion to be lower than that of pixel corresponding to the boundary portion when the boundary portion is viewed from a left-eye position.
