Abstract
The present invention forms overlapping regions on the boundaries of neighboring image regions in a block copy image. In the method of the invention, region numbers are allocated to separate image regions in an original image, and overlapping regions or frame regions of a predetermined width are created on the boundaries of the neighboring image regions while alternately applying an eight-neighbor window and a four-neighbor window (S52 and S57 ). Each window includes a center pixel and neighboring pixels with a predetermined priority. Region numbers are allocated to the frame regions based on the region numbers of the center pixel and the neighboring pixels and on the priorities. The color of each frame region is determined according to a predetermined method, which depends on printing types such as offset printing and gravure printing. Color components of each frame region are determined according to the color of the target frame region and the color of another frame region that is neighbor to the target frame region across the boundary of the original image regions.
