Abstract

In an image processing system, a color or monochrome image region in an image is discriminated, and communication charges are displayed, as required when regions of the image are encoded by appropriate encoding methods in units of the regions, and are transmitted to a designated destination. An operator switches an encoding method with reference to the displayed information, thereby determining appropriate encoding methods in units of displayed regions. Therefore, a transmission that sufficiently reflects the operator'"'"'s intention is achieved.
