An image processing device converts received color image data in accordance with a color gamut that an image output apparatus can express. A representative color is determined for each of a plurality of pixel aggregates formed by classifying pixels included in the color image data. An initial distribution of representative colors in a predetermined color space is set. An evaluation function takes a value increasing as a chroma difference between representative colors recedes from chroma that in the initial distribution. Apparatus color gamut data represents the color gamut that can be expressed by the image output apparatus chroma. After changing the chroma of a specific representative color in accordance with the color gamut of the image output apparatus, the chroma of the remaining representative colors is changed so that a summation of values of the evaluation function calculated between the representative colors becomes equal to or smaller than a predetermined value. The color image data with respect to each of the pixels is converted in accordance with the changes in the chroma of the representative colors chroma.

An image processing device carries out color conversion of a color value on a first color space into a color value on a second color space. The device includes a first color conversion unit that does not convert a color value corresponding to a gray axis in the first color space and carries out the color conversion so as to adapt a color value on the part other than the gray axis to a color area of the second color space; and a second color conversion unit that adjusts the gray axis in the first color space after the color conversion.
