Abstract
Regions 150 and 152 on a texture image plane 140 that correspond individually to pixels 146 and 148 representing an image on a texture image mapping target surface 144 in a screen plane 142 on which to define a display image are determined using predetermined transformation equations. The number of sampling points and their distribution are determined for the determined region in accordance with its shape and its size. Texel values in the determined region are then sampled. An average of the sampled values is acquired as the value of each of the original pixels 146 and 148.
Claims9
An image processing apparatus comprising:
- a corresponding region identifying section configured to determine, based on positional relations between a surface to which to map a texture image in a target space for rendering and a screen plane on which to define a display image, a region on the plane of the texture image in such a manner that the region corresponds to each of pixels representing the surface for mapping among the display image;
- and
- a pixel value calculating section configured to sample texel values in the corresponding region so as to determine and output the value of the pixel representing the surface for mapping,
- wherein the pixel value calculating section changes the number of sampling points in accordance with a size of the corresponding region.
