With an apparatus according to the present invention, when an input color gamut is compressed to an output color gamut, based on the difference value between the lightness of paper white and the lightness at the maximum chroma in the output color gamut of a predetermined hue, if the lightness difference is below a predetermined threshold value, a compression convergence point is set at a position at which lightness is lower than or equal to the lightness at the maximum chroma in the output color gamut. This suppresses reduction of the gradation in the direction of input chroma, and makes it possible to compress the input color gamut to the output color gamut such that excellent color reproduction is achieved while the gradations of lightness and chroma in the input color space are maintained.
