A spatial CAM forward conversion unit forward-converts XYZ data of the input side into JCh data based on input viewing condition parameters including parameters, which are used to determine field sizes of an input image based on the viewing angle. A Gamut mapping algorithm unit converts the JCh data into those in a color reproduction range of an output device by gamut mapping according to the color reproduction range of the output device. A spatial CAM inverse conversion unit inversely converts the JCh data in the color reproduction range of the output device into XYZ data of the output side based on output viewing condition parameters including parameters, which are used to determine field sizes of an output image based on the viewing angle. |
