中国人眼光谱相对视亮度函数的研究——Ⅳ.亮度级对光谱相对视亮度的影响

A SERIAL STUDY ON THE RELATIVE SPECTRAL LUMINOSITY AMONG CHINESE PEOPLE(Ⅳ)——INFLUENCE OF THE LUMINANCE LEVELS ON THE RELATIVE SPECTRAL LUMINOSITY

本研究主要采用闪烁光度法得到四个亮度级上的相对视亮度曲线。以此为基准进而又作出了相应亮度级上最小可觉明度差别阈限曲线。所得结果表明随亮度级增高,光谱相对视亮度发生变化:在可见光谱中段,保持不变,两端降低。

This work was undertaken by using the flicker method and JND Technique.Luminosity curves under the conditions of 4 luminance levels (correspond to7.62, 76.2, 762 and 7620 td)have been obtained.The results show that the V(λ)curves become slender when the luminosity rises, that is, as the luminancelevels increase, the sensitivity to the two ends of the visible spectrum decreas-es while that to the middle of the spectrum holds relatively invariable.
