摘要： A color image processing apparatus is disclosed wherein an edge portion of an achromatic area is detected to emphasize the edge portion and reduce the density of a chromatic area near the edge portion, and the reduced chromatic portion signal is further suppressed, such that the half tone area can be processed at high gradation and the black character and line image can be outputted in more black and with high resolution, resulting in less color bleeding.
