PROBLEM TO BE SOLVED: To provide an apparatus for gamut mapping and method of generating color boundary using the same. SOLUTION: A gamut-mapping apparatus includes a color-coordinate-conversion module which converts color coordinate values of an input color sample to values of a spherical coordinate system, and which divides the spherical coordinate system into a predetermined number of segments; a decision module which detects color coordinate values having a largest radius among color coordinate values included in the divided segments; and a gamut-boundary-setup module which detects the color coordinate value having a greatest radius, which is most adjacent to the center of each segment, according to the divided segments based on the detected color coordinate values having the largest radius, and which sets a gamut boundary. The spherical coordinate system is divided based on a hue value and a largest chroma value with respect to each hue. Thus, color reproduction performance between mutually different color input/output devices can be improved. COPYRIGHT: (C)2007,JPO&INPIT
