基于Gain-Offset-Gamma(GOG)模型,提出了CRT显示器色度校正的单参数(SP)模型.此模型表达简洁,计算简单,易编程实现.实验中分别采用SP模型和GOG模型测量了CRT显示器色度特性参数,并理论预测了CRT显示器屏幕色.实验结果表明,SP模型预测的阶调复现曲线(TRCs)比GOG模型更符合测量值;对于选用的CRT显示器屏幕色样,GOG模型预测值与测量值的最大色差△ECIE94为1.57,平均色差为1.11,而SP模型的预测值与测量值的最大色差△ECIE94为1.06,平均色差为0.618,比GOG模型预测有较小的色差.因此,SP模型将成为最简单、高精度的一种计算机控制CRT显示器颜色表述方法.
