摘要
基于CRT显示器的显色特性,在GOG模型特性化方法的基础上,考虑三通道相互干扰的影响,对模型进行改进。通过实验测试表明:改进后的模型可控精度达到平均色差0.48ΔEa*b,最大色差0.85ΔEab*,最小色差0.13ΔEa*b,低于目前CRT显示器颜色特性化的最高精度平均色差0.54ΔEa*b,即改进后的模型能有效地减小三通道的相互干扰影响。
Based on the color characteristics of CRT display and the GOG model characterization method,the model was improved on account of the mutual interference of three color channels.It is shown by experimental test that the controlled accuracy of the improved model reaches 0.48ΔE＊ab of average color difference,0.85ΔE＊ab of maximum color difference and 0.13ΔE＊ab of minimum color difference,being lower than 0.54ΔE＊ab of average color difference at maximum accuracy of color characteristics of the present CRT display.That means the improved model can effectively reduce the influence of mutual interference among three color channels.
