基于三维查找表的CRT色空间转换的研究

Research on CRT Color Space Conversions based on Looking-up Table

彩色显示器是用来传达颜色信息的重要工具,而色彩在不同设备和系统上往往会造成差异,因此对显示器建立一个色彩管理系统很有必要。采用三维查找表的方法建立了RGB-CIELab色彩空间转换模型,完成了模型的色差计算与精度分析,取得了较好的实验结果,为建立显示器的色彩管理系统提供了依据。

Color CRT is an important tool to communicate information and color display is often difference in various equipment and systems, Therefore, modeling of color management system is necessary for CRT. RGB-CIELab color conversion model was established based on looking-up table and the precision was analyzed. Good experimental results were obtained, which can provide useful reference for building color management system of CRT.
