摘要： A super-resolution processor in one aspect of the present invention first estimates a motion between an input image and a delayed input image which is obtained by delaying the input image by some frames, and determines a motion vector in super-resolution processing of adding a high frequency component using a learning database. Subsequently, the super-resolution processor updates an evaluation value evaluated when a patch is extracted in a target block of the input image, so that a learned high frequency patch is likely to be selected, the learned high frequency patch being the same as the learned high frequency patch used for super-resolution processing performed at the position motion-compensated by the motion vector in the frame at the same time as the time of the delayed input image.
