摘要： A gamut mapping method and apparatus are provided which allow a reproduction device to properly represent colors that are not within a gamut boundary of the reproduction device but within in a gamut boundary of a source device. The gamut mapping method includes (a) setting a cut-off rate for a predetermined color component and defining a cut-off region on a standard color circle; (b) determining a gamut of a reproduction device using color data which is part of basic color data and corresponds to colors that do not belong to the cut-off region; (c) modifying a gamut of a source device according to the determined gamut of the reproduction device; (d) determining a mapping relationship between the modified gamut of the source device and the determined gamut of the reproduction device; and (e) creating a mapping table based on the determined mapping relationship.
