An edge processing system for use in a color image processing device for reproducing images having a plurality of colors through its execution of repeated developing processes for the individual recording signals of the developed colors, comprises a low-pass digital filter for eliminating mesh dot components of the recording signals to smooth halftone images; a high-pass digital filter for detecting an edge part composed of high frequency components of the recording signals; a hue detector for detecting the hue of the recording signals to produce hue signals; an edge emphasizing signal generator for generating edge emphasizing signals according to the hue signals of the hue detecting means and the output signals of the high-pass digital filter; and a synthesizer for modulating and synthesizing the edge emphasizing signals and the output signals of the low-pass digital filter.
