摘要： 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.
