摘要
彩色显示器呈色域的确定是彩色管理系统中实现颜色空间转换的前提。不考虑亮度因素Ｙ而仅把在ＣＩＥ１９３１色度图上连接Ｒ、Ｇ、Ｂ三原色点形成的三角形区域认为是彩色显示器的呈色域，尚不能全面地描述显示器的呈色域。如果考虑亮度因素Ｙ，那么，在不同的呈色亮度下，其呈色域的形状与大小是不同的。本文就彩色显示器在不同呈色亮度下呈色域的确定问题进行实验研究。
Determination of the color display gamuts is the presupposition to convert color space in color management system.The triangular region produced by plotting the CIE1931 chromaticity coordinates of the red,green and blue display primaries and connecting them with straight line is often referred to as the color display gamut,which is not enough to describe generally the color display gamuts at all luminace.Because,the shape and size of color gamuts will change if the color luminance change.In this paper,the authors provide instruction on determining color display gamuts at all luminance.
