Abstract

An information processing apparatus ( 30 ) includes: an estimation unit ( 33 B) that estimates the crosstalk amount based on a relative positional relationship between a viewing position of a viewer of a display device ( 10 ) and a pixel a screen of the display device ( 10 ); and a generation unit ( 33 C) that generates an image to be displayed on the display device ( 10 ) by correcting a value of each of a plurality of pixels of the screen based on the crosstalk amount.

Claims (43)

generate two-dimensional images for respective viewpoints based on the viewing position; and

correct the value of the pixel according to the crosstalk amount from the two-dimensional images.

4. The information processing apparatus according to claim 3 , wherein in the generation of the image, the circuitry is further configured to:

calculate a light reduction rate for each of the plurality of pixels based on the crosstalk amount; and

reduce light of the image by convolution of each the two-dimensional images and the light reduction rate.

5. The information processing apparatus according to claim 3 , wherein the circuitry is further configured to:

estimate the crosstalk amount based on a difference between the viewing position and a pixel position indicating a position at which a light beam of the pixel spreads;

calculate, in the generation of the image, a display viewpoint position based on a relationship between the viewing position and the pixel position;

calculate, in the generation of the image, a light reduction rate for each of the plurality of pixels based on the display viewpoint position and the crosstalk amount; and

convolute, in the generation of the image, each of the two-dimensional images and the light reduction rate.

6. The information processing apparatus according to claim 3 , wherein the circuitry is further configured to:

estimate the crosstalk amount based on a difference between the viewing position and a pixel position indicating a position at which a light beam of the pixel spreads;

correct, in the generation of the image, a pixel value for the pixel position based on the crosstalk amount so as to bring a display viewpoint position of the pixel close to a display viewpoint position of the viewing position; and
