ABSTRACT:
A color image data compressing method wherein after the primary color signals of a digital color image have been converted into luminance signals and component color signals, these component color signals are compressed to generate compressed color signals, and the compressed color signals and the luminance signals are binarily processed, respectively, to form information-compressed binary images. The binary images are dither images by the dither method.
