ABSTRACT:
An image processing method is used to converting a color within a first color reproduction range that is a device-independent color space into a color within a second color reproduction range that is a color reproduction range of an output device. The image processing method includes defining, within the first color reproduction range, a third color reproduction range of a color that is estimated to be input; defining, within the second color reproduction range, a fourth color reproduction range that is smaller than the second color reproduction range; and, in performing the color conversion, compressing a color within the third color reproduction range into a color within the fourth color reproduction range and compressing a color within the first color reproduction range and outside the third color reproduction range into a color within the second color reproduction range and outside the fourth color reproduction range.
