摘要 在彩色显示器上新的主观色差评价实验表明:CIELUV颜色空间色差公式中彩度差的权重相对于明度差的权重而言显著偏高了. A new experiment was carried out on a modern HP-workstation with a 19' color screen under usual office lighting conditon. In the middle of the screen two adjacent fields of differnet colors were displayed, either 2° or 10° in size. Both of the fields were fixed to the same CIELUV color difference in relation to the background of the screen at 5, 20, 50 and 80 CIELUV units respectively. The task of the observer was to evaluate these adjustments-perceived color difference of the left field is bigger than, same as, or smaller than that of the right field. The result shows that equal CIELUV color differnces on displays lead to quite different subjective ratings. In particular, chroma in CIELUV system is very much overestimated.
