    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.

    摘要: A super-resolution processor includes an N enlargement unit that generates an N-enlarged image by enlarging the input image by a factor N; an M enlargement unit that generates an M-enlarged image by enlarging the input image by a factor M; and a high-pass filter unit that extracts a high-frequency component of the M-enlarged image, as an M-enlarged high-frequency image. Additionally, a patch extraction unit extracts an estimated patch of a predetermined size from the M-enlarged high-frequency image, the estimated patch being a part of the M-enlarged high-frequency image; and an addition unit adds the estimated patch to a processing target block of the predetermined size in the N-enlarged image, to generate the output image, where M is smaller than N.
