    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.

    摘要: An apparatus and method for image-adaptive color reproduction is provided. The apparatus includes an information-extraction unit, an image-compression unit and an image-information-reproduction unit. The information-extraction unit inputs image information of a first color space model, converts the input image information into image information of a second color space model, and extracts pixel frequency information of pixels belonging to a plurality of color regions by using the image information of the second color space model. The image compression unit inputs the image information of the first color space model, converts the input image information into the image information of the second color space model, and calculates compressed image information by compression-mapping the image information of the second color space model. The image information reproduction unit outputs final image information by using the pixel frequency information and the compressed image information.
