彩色复制中的色域映射

由于各种颜色设备能表现的颜色范围，即色域各不相同，用一个设备复制另一个设备的颜色时，可能无法原样再现。为了尽可能减少这种颜色失真，在复制前需进行设备间的色域映射操作，本文举例介绍了当前颜色复制系统中的色域映射技术和算，分析比较了各种方法及色域映射中的相关问题。

Color Gamut Mapping in Color Reproduction

Gamut mapping is a component of any color reproduction system and its task is to assign colors in a target device to colors from a source device. However, the gamut of colors reproducible on different devices are from each other greatly, and this would result in that some original colors can not be fully reproduced on the reproductions. Thus color mapping is a necessity when reproducing a color(or color image). The overview presented here pays emphasis on various color mapping algorithms and their effects based on a literature survey conducted.
