摘要

为了研究显示设备的原色光谱对色觉正常观察者的颜色分辨差异影响, 选择了5台红绿蓝三原色光谱能量分布不同的显示设备, 基于国际照明委员会推荐的5个颜色中心, 组织了30名年龄分布在20~27岁的色觉正常观察者基于5台显示设备开展颜色匹配实验。同时用108个颜色匹配函数对颜色匹配过程进行了模拟计算, 将计算结果与颜色匹配实验结果进行比较, 并用同色异谱指标量化不同显示设备对观察者差异性的影响, 发现模拟计算结果与颜色匹配实验结果具有较好的一致性。基于实验选取的4台待匹配设备与目标设备进行颜色匹配实验, 采集到285个CIELAB色差数据, 同色异谱指标的最大值为9.59, 最小值为3.89。显示设备的原色光谱对观察者同色异谱的影响较大, 红色受设备的影响低于黄色和蓝色。

Abstract

In order to investigate the influence of the primary spectrum of a display device on the color discrimination difference of observers with normal color vision, five display devices with different red, green and blue color primary spectral energy distributions are selected. Based on the 5 color stimuli recommended by CIE, 30 observers aged from 20 to 27 with normal color vision are organized to carry out the color-matching experiment based on these five display devices. Meanwhile, the 108 color-matching functions (CMFs) are used for the computational simulation of the color-matching process, and the calculation results are compared with the color-matching experimental ones. The influence of different display devices on the discrimination of observers is quantified by the metamerism index. It is found that the simulation results are well consistent with the color-matching experimental ones. With the 285 CIELAB color difference data acquired from the color-matching experiment based on the selected four display devices to be matched and the target display device, the maximum of 9.59 and the minimum of 3.89 as for the metamerism index are obtained. The primary color spectrum of a display device has a strong influence on the observer metamerism and the influence of a red color device is weaker than those of yellow and blue ones.
