ABSTRACT:
An image processing method according to the present invention achieves gamut mapping between devices having different color reproduction ranges in gamut compression, and enables good color reproduction without reversal of tonal change. An image processing method converts a color signal representing a color in a first color gamut to a color signal representing a color in a color gamut of an image forming apparatus. The image processing method includes modifying a shape of the color gamut of the image forming apparatus according to a shape of the first color gamut, and converting a color signal representing a color in the first color gamut to a color signal representing a color in the color gamut of the image forming apparatus.
