Abstract

There is a discrepancy between several studies that have shown the human luminous-efficiency function to vary with surround color and a recent study that failed to find this dependence. Data are presented that show that this discrepancy can be explained by differences in the matching techniques. Luminous efficiency measured by direct heterochromatic brightness matching does depend on surround color, whereas luminous efficiency measured by the flicker method does not. The independence of luminous efficiency as measured by flicker is evidence for an independent luminance channel.

独立亮度通道的证据。
有几项研究表明,人类的发光效率功能随着周围环境的颜色而变化,而最近的一项研究没有发现这种依赖关系,这两者之间存在差异。提出的数据表明,这种差异可以用匹配技术的差异来解释。直接异色亮度匹配法测得的发光效率与环绕色有关,而闪烁法测得的发光效率与环绕色无关。由闪烁测量的发光效率的独立性证明了一个独立的亮度通道。
