在两项实验中，使用模拟CRT显示器上呈现的照明表面来测量同时的颜色恒定性。受试者看到两个相同的蒙德里安并排：一个蒙德里安在标准光源下渲染，另一个在几个测试光源之一下渲染。在测试光源下调整匹配场，使其（a）具有相同的色调、饱和度和亮度（外观匹配）或（B）看起来像是从标准光源下的测试表面的同一张纸上剪下来的（表面匹配）。比赛设置为三个不同的表面收集。表面匹配比外观匹配表现出更高的恒定性水平。表面匹配的调整在L和M锥数据中几乎完成，并且偏离完美恒定性主要是由于S锥信号的调整失败。除了这种调整量的差异外，外观和表面匹配显示出两个主要的相似之处。首先，这两种类型的比赛都很好地描述了简单的参数模型。特别是，一个基于冯·克里斯调整概念的模型提供了一个很好的数据描述，尽管不是完美的。其次，对于这两种类型的匹配，光源调整在很大程度上独立于图像中的表面收集。所以，这两种比赛，只是量的不同，并没有质的区别。(C)1999爱思唯尔科技有限公司。保留所有权利。
In two experiments simultaneous color constancy was measured using simulations of illuminated surfaces presented on a CRT monitor. Subjects saw two identical Mondrians side-by-side: one Mondrian rendered under a standard illuminant, the other rendered under one of several test illuminants. The matching field was adjusted under the test illuminant so that it (a) had the same hue, saturation, and brightness (appearance match) or (b) looked as if it were cut from the same piece of paper (surface match) as a test surface under the standard illuminant. Matches were set for three different surface collections. The surface matches showed a much higher level of constancy than the appearance matches. The adjustment in the surface matches was nearly complete in the L and M cone data, and deviations from perfect constancy were mainly due to failures in the adjustment of the S cone signals. Besides this difference in amount of adjustment, the appearance and surface matches showed two major similarities. First, both types of matches were well described by simple parametric models. In particular, a model based on the notion of von Kries adjustment provided a good, although not perfect, description of the data. Second, for both types of matches the illuminant adjustment was largely independent of the surface collection in the image. The two types of matches thus differed only quantitatively, there was no qualitative difference between them. (C) 1999 Elsevier Science Ltd. All rights reserved.
