年轻和老年观察者的色差分辨差异研究

为了比较不同年龄段观察者的颜色色差评价差异, 研究视网膜锥细胞光谱响应分布差异, 基于灰色、棕色、蓝绿色、蓝色和紫色5个目标色, 共制作20对近同色异谱色样对。基于心理物理实验中的比较法, 对30名18~25岁和26名60~74岁观察者开展色差大小比较实验。结果表明, 不同年龄段观察者对20对近同色异谱色样对的色差大小表现出不同的评价规律, 所评估的目视色差呈负相关(协方差相关系数为-0.18), F检验差异显著。对灰色、棕色和蓝绿色的评价呈负相关(协方差相关系数分别为-0.99、-0.96、-0.84); 对蓝色和紫色的评价呈正相关(协方差相关系数分别为0.99、0.80)。

Abstract

We make 20 pairs of nearly metamerism color patches based on five target color of gray, brown, blue-green, blue and purple, to compare the color-difference discrimination and investigate the retinal spectral response distribution of the different age observers. We conduct the color-difference experiments on 30 observers aged from 18 to 25 and 26 observers aged from 60 to 74 with psychological paired-comparison. Experimental results indicate that the different age observers have different evaluation rules on the color-difference of 20 pairs of nearly metamerism color patches with the negative covariance correlation coefficient of -0.18, and significant F test results. The negative covariance correlation coefficients are -0.99, -0.96, -0.84 respectively in gray, brown and blue-green color regions, while, the positive covariance correlation coefficients are 0.99 and 0.80 in blue and purple color regions.
