Abstract
Perceived brightness is considered to be a combined consequence of out puts 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 th at were obtained from 16 subjects were examined by using principal com ponent analysis. The luminous-efficiency difference between the two me thods is described by only two principal components. Individual charac teristics of the contribution of chromatic channels to brightness can be specified by measuring luminous efficiencies at 470 and 660 nm.
