摘　　要：为了研究中国人眼在明度感知上的视觉特性,在液晶(LCD)显示器上显示颜色刺激,并采用心理物理实验,分别测得23名色觉正常的观察者在Adobe RGB空间中的白——黑系列明度知觉等级。采用性能因子PF/3讨论观察者的一致性测试精度,并得到中国人眼明度值(V)和亮度因素(Y)之间的5次多项式关系曲线。通过对实验数据的详细处理和对比分析表明中国人眼的明度值,以明度等级4.16作为分界点,在高明度一端,亮度因素值(Y)低于孟色尔体系明度曲线的结果,而在低明度一端,亮度因素值(Y)则高于孟色尔体系的结果。本文的实验结果可为中国颜色体系明度白——黑系列的进一步研究提供原始数据和参考依据。The brightness grade for white and black series among Chinese people was studied in the experiment.At the same time, the visual data at home and abroad were compared in order to study the Chinese human color vision characteristics .The color stimuli were displayed on the liquid crystal displays （ LCD） .The data were obtained through analyzing the lightness perception level in the Adobe RGB space . The performance factor of PF/3 would be used to discuss the observers ＆#39;test accuracy , and to obtain the curve of V-Y.Detailed processing and comparative analysis of the experimental data indicated that there was a nonlinear relation between the brightness values （ V） and the luminance factors （ Y） by using a five-order multinomial.Compared with the Munsell white and black series system , the values of luminance factors in the brightness grade of white and black series were different .The experimental results in this paper can provide raw data and reference for further study .
