Abstract: An image processing device includes: a first color conversion processor configured to perform first color conversion processing on image data; a second color conversion processor configured to perform second color conversion processing on the image data; a coefficient calculator configured to calculate a coefficient indicating a blend ratio between an output of the first color conversion processor and an output of the second color conversion processor; and a blend processor configured to blend the output of the first color conversion processor and the output of the second color conversion processor based on the ratio indicated by the coefficient, wherein the coefficient calculator calculates a position on an xy chromaticity diagram of a color indicated by each pixel in image data processed by the first color conversion processor to determine the coefficient based on a distance from the calculated position to a boundary of a color gamut.
