摘要

Apparatuses and methods for performing gamut compression. A gamut mapping apparatus of the invention includes a gamut analyzing unit for analyzing the gamut of a source device and the gamut of a target device using a gamut information profile; a gamut compressing unit for mapping original images of the source device within the gamut of the target device by using the analytical information on the gamuts; and a gamut extending unit for increasing the chroma of predetermined images among the compressed original images on the basis of the analytical information on the gamuts and the performance result of the gamut compressing unit.
