摘要
用双眼不对称匹配法研究人眼在观察计算机视觉显示终端彩色监视器荧光屏时,视觉系统对复杂背景的色适应及其对荧光屏显示色貌的影响.研究结果表明,背景的平均颜色和目标与背景的色差及亮度差对色适应引起的色位移有显著的影响.在定量估计人眼对复杂背景的色适应引起的色貌变化时,可以把视觉系统看作一个积分响应灵敏度取决于背景颜色和亮度平均值的信息处理系统。
The effect of chromatic adaptation of the human visual system to a complex background upon the color appearance of information displays is investigated with the binocular asymmetric matching method applied to the observation of color monitor screens in computer visual display terminals (VDT). The results of experiments show that there exist significant influence of surrounding average color, brightness and color differences between the target and its surrounding on color shifts evoked by chromatic adaptation. In assessing the color appearance induced by complex background, the human visual system can be treated as an information processing system in which the integrated response sensitivity varies with the average color and brightness of background.
