US Patent 7688363 Super-resolution device, super-resolution method, super-resolution program, and super-resolution system

An albedo estimating section produces an albedo image of an object from an original image captured by an image-capturing section by using light source information estimated by a light source information estimating section and shape information of the object obtained by a shape information obtaining section. An albedo super-resolution section performs super-resolution of the albedo image according to a conversion rule obtained from an albedo DB. A super-resolution section produces a high-resolution image obtained by performing super-resolution of the original image by using the super-resolution albedo image, the light source information and the shape information.
