摘要
结合CRT显示器的显色特性,基于线性插值的方法,对GOG模型进行改进,提出了一种新的考虑三电子枪相互干扰和环境亮度等影响因素的精确控制CRT显示器色度和色差的模型。通过实验测量和理论计算,结果表明,提出的模型颜色控制精度能够达到色度Y,L*,a*,b*的平均可控精度分别为0.255 4,0.280 4,0.072 5,0.125 5,可控色差精度为0.350 7ΔEa*b,模型比现有的GOG模型在精度控制上有较大的提高。
Gain offset gamma model was improved based on linear interpolation method according to CRT display color rendering characteristics. A new model was put forward to precisely control chromaticity and color difference of CRT display, which considered three channels interference each other and the environment brightness influence, and as on. The model was verified by experimental measurement and theoretical calculation. The results showed that average controllable precision of the color of Y, L＊ , a＊ , b＊ of the proposed model is 0. 255 4, 0. 280 4, 0. 072 5, and 0. 125 5 respectively; controllable chromatic aberration is 0. 350 7AEo; , which means that the proposed model has more greatly improved control precision than the existing GOG models.
