摘要
采用同一设置的阴极射线管显示器显示目标光栅,测量了在暗室、3种常见照明灯光和室内自然环境条件下的人眼对比度敏感觉察阈值,获得了日常生活环境下的人眼对比度敏感函数,测量结果与国外测量结果进行了比较和讨论,全面地研究了人眼对比度敏感视觉特性受环境亮度的影响。
The contrast detection threshold under the darkroom,three kinds of common lamplights and the room natural environment are obtained by viewing the gratings displayed on a CRT with the same parameter.CSF of human vision system under daily life environment is obtained.Measurement results are compared with foreign previous ones.The effect of environment brightness on the contrast sensitivity of human vision system is studied.
