| 摘 要： | 在均匀颜色空间的颜色差别计箅中,亮度和色彩的作用是相关且不同的,尤其是在目标尺度对人眼张角(亦称视角)小于30角度分的条件下观察,由于亮度差和色彩差受视角变化的影响程度不同步,使得人眼颜色差别分辨阈亦不确定。本文通过一定的试验和计算,探讨了在不同的亮度差和色彩差的情况下,颜色差别阈受视角影响的变化规律。

| Abstract: | The luminance and chromaticity play different and relative roles in the color difference calculation of the uniform color scales space. Specially, under the condition of small angular subtenses, the varying magnitudes of luminance contrast and chromatic difference make the visual thresholds changeable. The various thresholds influenced by contrast and chromaticities with small subtenses were described by means of the experiment and calculation in this paper. |
