ABSTRACT:
A digital copying machine provided with a device for forming color images by the formation, superposition of the images for each color in the order of the color face including a device for coding, compressing of a plurality of image signals separated in color by one page portion of the document so as to store in memory, a device for decoding, extending a plurality of compressed image signals stored in the memory, a color correcting device for converting a plurality of extended image signals into the color image signals for image formation so as to make the memory capacity smaller.
