摘要
微软公司推出的Windows Vista操作系统采用WCS(Windows ColorSystem)色彩管理系统,利用基于测量的设备特性文件,结合相应的设备模型,得到设备颜色空间和标准颜色空间之间的映射.WCS采用CIECAM02色貌模型,所有的颜色转换都在CIECAM02中进行,从而可以预测不同视觉条件下的颜色视觉属性.本论文首先在分析研究由微软和佳能公司联合开发的新一代基于色貌模型CIECAM02的WCS色彩管理的特点和工作流程基础上,根据WCS设备模型特性文件方案和显示器测量数据,利用XML语言编写了显示器的WCS设备模型特性文件,设计出利用显示器模拟跨媒体色彩传输的实验路径和方法,使得跨媒体传输色彩的结果可以直观地进行评价;对ICC色彩管理系统下输出的图像和在WCS色彩管理系统下输出的图像进行了比较.结果进一步证实,WCS色彩管理系统较ICC色彩管理系统具有在色彩实时转换和跨媒体方面的优点.本课题的研究成果对利用WCS色彩管理系统实现高保真的色彩复制具有一定的指导意义.
The Microsoft Windows Vista operating system provides WCS (Windows Color System) color manage system, mapping between device color space and standard color space has been using measurement-based device model profile which combined with relevant device model. CIECAM02 color appearance model has been adopted in WCS as color translation space, so that color vision attribute of different vision condition could be forecasted. On the basic of researching on characteristic and work flow of WCS color management which developed by Microsoft and Canon company, according to WCS device model profile scheme and measurement data of display, using XML format to write a device model profile, by designing an experiment method of using display to simulate color cross-media transmission, the result of cross-media color transmission has been evaluated directly; the result of comparing images which separately output by ICC color management system and WCS color management system has further confirmed the strongpoint of WCS color management system in color real-time translation and cross-media reproduction. This paper's research result makes certain guide .sense on implementing high quality color reproduction with WCS color management system.
