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.
多项研究表明人类的发光效率函数会随周围颜色而变化，而最近一项研究却未能发现这种依赖性，两者之间存在差异。本文给出的数据表明，这种差异可以通过匹配技术的不同来解释。通过直接异色亮度匹配测量的发光效率确实取决于周围颜色，而通过闪烁法测量的发光效率则不然。通过闪烁测量的发光效率的独立性是存在独立亮度通道的证据。
