Albedo estimation unit (206), by using the shape information of the object obtained shape information obtaining section and light source information, the estimated light source information estimating section (203) through (204), captured by the (201) image pickup unit from the original image, which is, I want to create an albedo image of the subject. Albedo high-resolution section (207), high resolution of the albedo image according to the conversion rules obtained from (208) albedo DB. Albedo image having the resolution thereof increased, using shape information and light source information, the image resolution increasing unit (217) generates a high-resolution image high resolution of the original image.
