亮度衬比
2) Luminance contrast
亮度对比
1.
Using quantitative psychophysical measurements, the effects of luminance contrast(LC) and equiluminance color contrast (ECC) between components of illusory figureson the magnitudes of orientation illusion (Zoellner illusion), length illusion (Muller-Lyer illusion and Ponzo illusion) and area illusion (Delboeuf illusion) were investigated.
用定量的心理物理测量方法,研究了错觉图形组成成分间的亮度对比和颜色对比对方位错觉(Zoellner错觉)、长度错觉(Muller-Lyer错觉和Ponzo错觉)及面积错觉(Delboeuf错觉)幅度的影响。
3) luminance ratio
亮度比
1.
The paper studies the influence of luminance,luminance ratio and the light sources on the lighting environment and provides reference and gist for the illumination design and further research.
目的研究亮度、亮度比、光源等因素对照明环境的影响,为照明设计的进一步研究提供参考和依据。
5) brightness contrast
亮度对比
1.
The brightness contrast and color difference are two regular independent criterions which have been used to test the color of camouflage paints,but their relation was neglected in previous studies.
在检测军用伪装涂料颜色时,经常将亮度对比和色差容限这两个检测指标独立使用,而忽略了它们之间的关联性。

亮度对比
luminance contrast
亮度对比(luminanee eontrast)视野中目标与背景的亮度差与背景(或目标)亮度之比。其常用表达式为: _}入一几} C二上二二-一止卫 乓 式中C为亮度对比，L，为目标亮度(edzmZ)，乙。为背景亮度(edzmZ)。一般情况下，以面积较大部分为背景，以面积较小部分为目标。对于均匀照明的无光泽的背景和目标，亮度对比可用反射率表示: lP一只I C=上二-一一州. 凡式中p，为目标反射率，尸，为背景反射率。 (许百华撰朱祖样审)
