Abstract

Additivity of heterochromatic brightness matching was investigated between unique-green and red (660 nm), and between unique-blue and unique-yellow with 2-deg bipartite field composed of a 100 td white reference field and a bichromatic mixture field. Ten subjects participated in the measurements and the results showed wide varieties among subjects. Previous models for brightness perception based on the contributions of red-green and yellow-blue opponent channels can explain some properties of the results, but they fail to explain other aspects. To overcome the difficulties, a new model is proposed for the brightness perception at photopic levels.

摘要

利用由100 td白色参考场和双色混合场组成的2度二分视野，研究了独特绿色与红色（660纳米）之间以及独特蓝色与独特黄色之间的异色亮度匹配的可加性。十名受试者参与了测量，结果显示受试者之间存在很大差异。以往基于红-绿和黄-蓝对立通道贡献的亮度感知模型可以解释结果的一些特性，但无法解释其他方面。为克服这些困难，提出了一种用于明视觉水平亮度感知的新模型。
