Abstract
A technology for creating an arbitrary viewpoint image with high quality based on pixel value information as seen from a single viewpoint and real spatial positional information has not been known. A hidden point is extracted based on a relative positional relationship between a single viewpoint closed surface projection point for arbitrary measurement point and neighboring projection point, a relative positional relationship between other viewpoint closed surface projection point for arbitrary measurement point and neighboring projection point, distance from arbitrary measurement point to another viewpoint, and distance from measurement point projected onto neighboring projection point on the other viewpoint closed surface to another viewpoint. Furthermore, the projection point pixel value on the other viewpoint closed surface for the extracted hidden point is corrected using distance from measurement point projected onto neighboring projection point on the other viewpoint closed surface to the other viewpoint and the measurement point pixel value.
