摘　　要：彩色显示器是用来传达颜色信息的重要工具,而色彩在不同设备和系统上往往会造成差异,因此对显示器建立一个色彩管理系统很有必要。采用阶调/矩阵方法建立了RGB- CIEXYZ色彩空间转换模型,分别运用多项式回归和指数回归算法对模型进行了曲线拟合,通过挑选不同的特征点完成了模型的色差计算与精度分析,取得了较好的实验结果,为建立显示器的色彩管理系统提供了依据。Color CRT is an important tool to communicate information and color is often different in various equipment and systems. Therefore, modeling a color management system is necessary for CRT. This paper adopts tone/matrix approach to build a RGB-CIEXYZ color conversion model, and curves are analyzed using polynomial regression and exponential regression. Then, the color difference of this model is calculated based on selecting different characteristic points and the precision is analyzed and nice experimental result is obtained, which can provide useful reference for building color management system of CRT.
