感知亮度被认为是视觉系统中亮度通道和色度通道的输出的组合结果。用主成分分析方法比较了16名受试者的异色亮度匹配与闪烁测光的对数光谱发光效率的差异。两种方法之间的光效差异仅用两个主成分来描述。通过测量470和660 nm处的发光效率，可以确定彩色通道对亮度贡献的各个特性。
Perceived brightness is considered to be a combined consequence of outputs of the luminance channel and the chromatic channels in the visual system. The differences of logarithmic spectral luminous efficiencies between heterochromatic brightness matching and flicker photometry that were obtained from 16 subjects were examined by using principal component analysis. The luminous-efficiency difference between the two methods is described by only two principal components. Individual characteristics of the contribution of chromatic channels to brightness can be specified by measuring luminous efficiencies at 470 and 660 nm.
