Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method and apparatus for performing gamut mapping between heterogeneous devices, to map a color of a device to an identical or visually and sensually preferable color of another device having a different color gamut. SOLUTION: The method includes: adjusting lightness of a color of a source device by scaling to match a lightness range of the source device with a lightness range of a destination device; modifying the adjusted lightness of the color of the source device by adjusting a color gamut of the source device to a color gamut of the destination device; and mapping the modified color of the source device to a color in the color gamut of the destination device.
