ABSTRACT:
An input color signal is converted into a color signal representing a color which is visually closer to a color represented by the input color signal by performing gamut mapping processing based on the visual characteristics of humans. An image processing method includes the steps of inputting color signals, and performing gamut mapping processing in which the input color signal is converted into a color signal having a hue different from the hue of the input color signal based on a locus set corresponding to the hue and color saturation of the input color signal in color space.
