摘要： The profile of a reference color space is acquired, and the acquired profile is converted into the profile of a uniform color appearance space which is a color space different from the reference color space. An evaluation value of color in the profile of the uniform color appearance space is calculated, and the profile of the uniform color appearance space is corrected based on the calculated evaluation value. The corrected profile is inversely converted into the profile of the reference color space.

摘要： When performing color conversion using a color conversion table which has signal values of an output color space corresponding to grid points dividing an input color space into a plurality of unit cubes, a quadrant to which an input signal belongs is determined, in a chromaticity plane perpendicular to a lightness axis of the input color space. A unit cube to which the input signal belongs is detected in the plurality of unit cubes. The detected unit cube is divided into a plurality of polyhedrons for interpolation operation by a segmentation method corresponding to the determined quadrant. The divide of the detected unit cube is performed along a direction of a diagonal line, which passes through an origin of the chromaticity plane, in a part of the plurality of unit cubes in accordance with the segmentation method.
