摘要

为了获得人眼视觉特性并直接指导工程设计和工效学评价等应用，基于显示器广泛使用的RGB颜色空间，提出了一种彩色对比敏感度定义。首先，生成了彩色对比敏感度阈值测量方法，然后，采集了12名被测试者先后两次每次3个颜色变量10个空间频率的彩色对比敏感度阈值。最后，通过Pearson检验分析先后两次测量结果的相关性，同时绘制出该人群R、G、B三种颜色变量彩色对比敏感度曲线。先后两次测量结果显著相关，R、G、B三种颜色变量对比敏感度曲线变化趋势相似，在空间频率为0.1和0.2 cycle/degree时，分辨阈限显著升高，且R变量分辨阈值整体高于G变量和B变量分辨阈值。测量方法稳定可靠，在极低空间频率时，被测试者分辨阈限较高，对红色核心颜色差异分辨力较弱。

Abstract

In order to obtain the specific characteristics of human visual system and support engineering design and ergonomic evaluation directly

a kind of chromatic contrast sensitivity was defined according to RGB color space which was widely used by display equipment. First

a threshold measurement method of chromatic contrast sensitivity was generated.Then 12 participants' data which contained two time periods

three variables and ten spatial frequencies were collected. Finally

Pearsontest analysis was used to measure the correlation of results in two time periods

and chromatic contrast sensitivity curve of three variables (R

B) was drawn. The analysis results showed that measuring results in two time periods were significantly correlated. The tendency of three variables' contrast sensitivity curves was similar and the threshold significantly increased when the spatial frequency came to 0.1 and 0.2 cycle/degree. The threshold value of variable R was higher than that of variable G and B on the whole.The reliability of measurement method was verified besides the threshold was high at extremely low spatial frequency and the participants were weak in distinguishing minor differences of red.
