关于照明与颜色视觉的研究

A Study about Illumination and Colors Vision

本文提出用软件算法来模拟人眼的颜色视觉。根据色标光谱图像、人眼锥体细胞感光灵敏度以及光源光谱能量分布,得到了一个光谱图像处理算法。实验中使用3种真实日光灯的光谱,分别为EG&G PerkinElmer制造的5500K日光灯、氙弧灯及CW灯,同时还使用了3个CIE标准照明光源,即D_(65),A光源及F7光源。为了证实算法在使用中的正确性,模拟了以上6种不同光源照明条件下,所得色标显色效果与色差大小。

In this paper we propose a software algorithm which can simulate the human eyes colors view. We present a spectral image processing algorithm, in which we use the color checker spectral image, the human eyes cones spectral sensitivity and the spectral power distribution for light sources. We use three spectrums of real lamps, made by EG＆G PerkinElmer： sunlight 5500K, xenon flash and xenon CW, and three CIE light standard sources： D65, CIE A and F7. In order to validate the functionality of the algorithm we simulate the color checker picture hues difference, under different illuminations generate with the light spectrums presented in this paper.
