Abstract:
1. A color adjustment method for obtaining a coefficient for performing color conversion of input color space into output color space with respect to a predetermined adjustment object region within color space to which a color image belongs, the color adjustment method comprising: obtaining a coefficient for converting a color within the adjustment object region into another color on the output color space, which is the same color spaceas the input color space, with maintaining continuity of gradations and not causing color inversion within the adjustment object region, wherein the adjustment object region includes: determining a representative color, which represents colors in the movement source partial color space; determining a target color, which represents colors in the movement destination partial color space and a target of the color processed by the color conversion; obtaining a fundamental vector indicating movement in the color space from the representative color to the target color; moving image data included in the adjustment object region in the color space in accordance with a direction and a distance, which the fundamental vector indicates; and making an amount of the movement at a boundary of the adjustment object region be substantially zero.
