Abstract
A method in which the distribution of a retouch coefficient in a subject region is specified by two data tables so that the retouch coefficient is readily changed at a high speed. A distance table 61 includes distance data Dd each representing a distance between a center pixel and each of the other pixels. A coefficient table 62 includes values of a retouch coefficient Kb dependent on the distance data Dd. The retouch coefficient Kb is changed by only rewriting the coefficient table 62. The retouch coefficient Kb at each pixel is determined based on the distance table 61 and the coefficient table 62 and is added to image data Di to modify the image data Dr.
