摘要
传统阴极射线管(CRT)色度预测模型大都建立在三刺激值的可加性原理之上。但是在实际应用中由于红绿蓝(RGB)三个通道之间存在相互干扰,使得红绿蓝的颜色合成结果在一定程度上偏离了叠加原理,因此传统阴极射线管色度预测模型必然产生相干误差。通过实验表明,红绿蓝三个通道之间的干扰主要表现为一种相互抑制作用,因此造成的传统阴极射线管色度预测模型的预测色差随显示亮度的增加而加大
Abstract
Up to now, almost all conventional cathode ray tube (CRT) colorimetric prediction models are based on the “superposition principle of tristimulus values”. Through a series of experiments. It is found that there exists a kind of “suppressive effect” among RGB channels in practical CRTs, and this effect will invalidate the superposition principle and result in the interactive errors in conventional CRT colorimetric prediction models. The experimetal results show the errors caused by this “interaction effect” will increase with the luminance values on the CRT screen.
