CIELUV色差计算公式的实验修正

通过在彩色显示器上所做的主观色差评价实验获得了对ＣＩＥＬＵＶ颜色空间差公式的线性校正，利用校正后的色差公式计算的结果与视觉的主观色差评价十分吻合。

Experimental Correction of the CIELUV System

A new experiment was carried out on a modern HP-workstation with the hope of providing a better agreement between corrected CIELUV value and subjective estimation of color differences. In the middle of a 19" screen two adjacent fields (2° or 10° in size) of different colors were shown. The left field was fixed at 5, 30, 50 and 70 CIELUV units respectively, and the color on the right field could be changed by verying its saturation and luminance. Observers were asked to adjust both colors to the same perceived color difference in relation to the background. The result shows that it was possible to achieve good agreement between predicted and perceived color differences by using a linear correction of the color coordinates u* and v*.
