Abstract

A color signal emphasizing/de-emphasizing method and apparatus are for outputting image data scanned from the target image in every pixel on a color print or a color display by means of three principle color signals. This method and apparatus are intended to obtain a desired hue variation or color saturation by emphasizing/de-emphasizing one of the three principle color signals. The three principle colors are classified into a primary color portion signal, a secondary color portion signal and tertiary color portion signal. These designated signals of color portions are respectively multiplied by color coefficients predetermined for each designated signal. Finally, a corrected color signal is obtained by summing up these multiplied signals in every principle color.
