摘　　要：色域匹配是数码彩扩机实现图像颜色较好再现的关键首先,采用一种较为实用的方法对CRT显示器进行了标定,运用Beer色料理论预测了彩色相纸的色域在此基础上,运用非线性压缩算法实现从CRT到彩色相纸的色域匹配,同时提出了虚拟色域的概念,并加以分析研究结果表明。Gamut mapping is the key element to get satisfactory image reproduction. First, a practical method is used to realize the transform from RGB values of CRT monitor to spectral tristimulus values. The printing paper gamut is predicted by Beer′s law. Further, a non-linear compression method is proposed to realize the gamut mapping. At the same time, the virtual gamut is defined and studied. The result indicates that this model has good practicality for the CMS (Color Management System) of digital photofinishing. This method is applied to high-technology industry with satisfying performance.
