“Windows”平台下显示器色彩再现机理的研究和分析
Color reproduction mechanism of monitor based on “Windows” platform
摘要
计算机操作系统中的颜色管理设置对显示器的正确显色起着十分重要的作用。针对此问题, 本文借助Windows7平台下的图形图像处理软件“Adobe PhotoShop”, 按照操作系统级和应用程序级颜色配置文件的不同, 分3种情况设计了不同的颜色显示方案, 并通过色差计算和色域比较的方法分析了操作系统级颜色配置文件在显示器颜色再现中所起的作用, 所得重要结论如下: 如果将操作系统级颜色配置文件设置为显示器自身的ICC特性文件, 那么显示器的显色效果变化被看作是应用程序级ICC对颜色色度值进行重新定义的结果; 如果将操作系统级颜色配置文件设置为其它ICC, 则会发生从操作系统级ICC到应用程序级ICC的颜色空间转换, 且两者的色域差别越大, 转换后的显色效果变化就越剧烈。本研究结论对于正确应用显示器色彩管理具有一定的指导意义。
Abstract
The color management settings in the computer operating system have an important influence on the correct color rendering of monitor. For this problem, by means of the image processing software "Adobe PhotoShop" under Windows7 platform, the three color rendering schemes were designed depending on different Operating System ICC and Application ICC. The methods of Color Difference Calculation and Gamut Comparison were used to analyzed the influence of Operating System ICC on color rendering of monitor. The important conclusions are as follows: If the ICC profile made for the monitor was set as Operating System ICC, the color rendering effect of the monitor can be seen as a redefined result of the chromaticity by Application ICC. If the other ICC profile was set as Operating System ICC, the displaying colors will be converted to color space of Operating System ICC from color space of Application ICC. The greater the gamut difference between the two ICC profiles is, the greater the variations of the converted colors are. The conclusions of this study have some guiding significance for the application of monitor color management.
