摘要： PROBLEM TO BE SOLVED: To provide a method for generating an interpolated image capable of reducing the occurrence of block distortion.
SOLUTION: Differential blocks 102, 103 are obtained by recursively reducing the differential block 101 of a pair of blocks obtained by block matching. The differential block 103 is compared with a threshold map 113. When the differential block 103 is equal to a threshold or larger, mismatching is determined. When the differential block 103 is less than the threshold, matching is determined. Based on the determined result, the threshold of the threshold map 112 is set high in a region corresponding to a matching region, and is set low in a region corresponding to a mismatching region. Subsequently, the processing is repeated up to an original block hierarchy, and the interpolated image is generated only by using the matching region. The mismatching region is searched again.
