Zusammenfassung:PROBLEM TO BE SOLVED: To provide a super-resolution processor capable of generating a natural and high-definition high-resolution image even for texture in an image. SOLUTION: A super-resolution processor 100 includes: an N enlargement unit 101 that generates an N-enlarged image 122 by enlarging an input image 121 by a factor N; an M enlargement unit 104 that generates an M-enlarged image 125 by enlarging the input image 121 by a factor M smaller than N; a high-pass filter unit 106 that extracts a high-frequency component of the M-enlarged image 125, as an M-enlarged high-frequency image 128; a patch extraction unit 108 that extracts an estimated patch 129 of a predetermined size from the M-enlarged high-frequency image 128, the estimated patch being a part of the M-enlarged high-frequency image 128; and an addition unit 109 that adds the estimated patch 129 to a processing target block of the predetermined size in the N-enlarged image 122, to generate the output image 131.
