IMAGE HIGH-RESOLUTION UPGRADING DEVICE, IMAGE HIGH-RESOLUTION UPGRADING METHOD, IMAGE HIGH-RESOLUTION UPGRADING PROGRAM AND IMAGE HIGH-RESOLUTION UPGRADING SYSTEM

摘要

An albedo estimating unit (206) makes out an albedo image of an object from an original image picked up by an image pickup unit (201) by using light source information estimated by a light source information estimating unit (203) and shape information of the object acquired by a shape information acquiring unit (204). An albedo high-resolution upgrading unit (207) upgrades the albedo image to be higher in resolution in accordance with transforming rules acquired from an albedo DB (208). An image high-resolution upgrading unit (217) makes out a high-resolution image that is a higher resolution upgraded original image by using the higher resolution upgraded albedo image, the light source information and the shape information.
