ABSTRACT:
A target region and a pin hole size are specified in a block copy image, which is divided into plural separate regions. The size of each separate region in the target region is calculated and compared with the pin hole size. The separate region smaller than the pin hole size is extracted as a possible pin hole area and filled with the color of its surrounding area, thereby the pin holes are eliminated.
