| 摘 要： | 为了对颜色视觉匹配中的明度阈值特性进行评价,采用在阴极射线管显示器上获得的颜色刺激,在5个不同明度的中性色背景下,标准刺激的明度L*从5到95以5个CIELAB单位为变化步长,共对19个不同明度的中性标准颜色进行视觉匹配实验。通过对实验结果的处理和分析,验证了关于颜色刺激视觉辨别明度阈值与背景明度之间相关性的韦伯法则和crispening效应,同时利用颜色视觉匹配数据对基于CIELAB的相关色差公式进行了评价和比较,CIEDE2000具有最好的明度差预测性能,CMC次之,CIELAB和CIE94最差。

| Abstract: | For the evaluation of lightness threshold characteristics of the visual color matching the experiment is carried out.By using cathode-ray tube(CRT)-generated color stimuli under five different gray backgrounds,the visual color matching is achieved for 19 neutral standard stimuli with their lightness L~* ranging from 5 to 95 by the step of 5 CIELAB unit.Upon the data processing and the analysis of the experimental results,the crispening effect and the(Weber's) law,which are about the correlation between the visual lightness discrimination threshold of color stimuli and the lightness of the background,are validated.Furthermore the visual color matching data from the present experiment are used to evaluate the CIELAB-based related aberration formulae.For the lightness-difference predicting,the CIEDE2000 outperforms the others,followed by CMC,and with CIE94 and CIELAB the poorest. |
