显示器的研究人员经常面对这样的问题 :就是在其设计的显示系统同标准显示系统之间存在色域偏差 ,因而 ,他们引入了色域转换的方法来克服这一问题。为了能准确表示一个显示系统所表现的颜色 ,CIE色度图常常用来描述该显示系统所复现的颜色坐标范围。在不同的显示系统中 ,由于其基色的特性不同 ,从而带来其显示色域的不同。目前 ,因为CRT广泛的应用和许多历史原因 ,使得CRT被公认为标准的显示系统 ,而其显示色域也自然成为准色域。这样产生的一个后果就是 ,许多显示系统的设计人员不得不放弃自有显示系统的色域 ,并设法将其转换到标准色域。由于多种因素的影响 ,转换后的色域往往仍然存在着较大的偏差。本文在色域的三维模型上对转换误差进行分析 ,评估色域转换的质量 ;同时 ,在分析这种偏差的基础上 ,详细论述了色域量化误差影响效应 Researchers in monitors often face the problem of color gamut deviations between the display system they design and the standard display system, so they introduced a method of color gamut conversion to overcome this problem. In order to accurately represent the color represented by a display system, the CIE chromaticity diagram is often used to describe the range of color coordinates reproduced by the display system. In different display systems, due to the different characteristics of their primary colors, resulting in the display of different color gamut. At present, because CRT is widely used and many historical reasons, making CRT is recognized as a standard display system, and its display color gamut naturally becomes quasi-color gamut. One consequence of this is that many designers of display systems have had to relinquish their own display system’s gamut and try to convert it to a standard color gamut. Due to a variety of factors, the converted color gamut often there is still a large deviation. This paper analyzes the conversion error on the three-dimensional model of the color gamut to evaluate the quality of the color gamut conversion. At the same time, based on the analysis of the deviation, the influence of the quantization error of the color gamut
