ABSTRACT:
In compressing a static image, image data is displayed in the window on the display unit, and the operator specifies a segmented rectangle. The specific coordinates of the segmented rectangle are stored as positional coordinate information, and are amended in an amending process so that the segmented rectangle may not destroy the basic blocks used in the compressing process. The image segmented by the amended and segmented rectangle is an image formed by basic blocks, and the data is not rounded in the recompressing process, thereby successfully maintaining the quality of the image.
