摘要

An input chromaticity data calculation unit 113 calculates input chromaticity data rg from device-dependent color data RGB. A chromaticity data transformation unit 114 transforms the input chromaticity data rg into output chromaticity data xy by referring to an LUT stored by an LUT storage unit 13. A total amount calculation unit 115 refers to the LUT of the LUT storage unit 13 to calculate a total amount Σ′_XYZ of the device-independent color data XYZ from the color data RGB. An output color data calculation unit 116 uses the total amount Σ′_XYZ to calculate color data XYZ from the output chromaticity data xy.
