摘　　要：在计算机演示色品图时，需人为设定代表亮度的三刺激值Ｙ，而Ｙ值的大小对显示器的色域及色品图的演示效果有很大影响。在导出含参量Ｙ的色域方程的基础上。When we demonstrate the CIE chromaticity diagrams on a computer control displayer, we must set the value Y which is one of tristimulus and represents the brightness. The value Y has a great influence on the color gamut of the monitor and the perception of the chromaticity diagrams. On the basis of a set of formula with parameter Y about the color gamut, a 2 dimension distributed function is set up in this article to determine the brightness at each pixel point in the CIE chromaticity diagrams.
