Abstract

There have been many researches related to metamerism, because of the importance. Among them, Cohen R-Matrix systematized G. Wyszecki’s hypothesis in which a spectral radiance distribution is decomposed into the fundamental component and the metameric black component. This article discusses related to R-Matrix. We have derived the equation describing metameric blacks from our original point of view. First, it is proved that our equation is equivalent to the logic in the R-Matrix operation. Second, the zero-crossing problem of the metameric black is discussed, extracted from the spectral radiance distribution of equal energy by using R-Matrix.
