摘要

The present invention is applied, for example, to resolution conversion. An edge gradient direction vl with the largest gradient of pixel values and an edge direction v2 orthogonal to the edge gradient direction vl are detected. Edge enhancement and smoothing processing are performed in the edge gradient direction vl and in the edge direction v2, respectively, to generate output image data D2.
