Abstract
A color image editing apparatus capable of improving color detecting accuracy, color-converting a chromatic color into a neutral (achromatic) color and vice verse and performing a hue conversion, while maintaining gradation. The color image editing apparatus in which image signals read out by an image reading unit are converted to density, hue and chroma signals by color display coordinate system convertor to perform a color image editing operation inlcudes a detector for detecting whether or not density, hue and chroma of a detected color image is within predetermined density, hue and chroma ranges, respectively. It is judged by a judging unit whether or not a color of the detected color image is of a predetermined color in responses to an output of the detector, and a color changing unit means converts the density, hue and chroma independently in response to the judgement result of the judging unit.
