Abstract

The material property of glossiness, which is attributed to many objects in our daily life, is physically independent of the objects' color. However, perceived glossiness can change with the contrast between the highlight and the area around the specular highlight. Hitherto, experiments mainly investigated gloss on unicolored surfaces. It is well known that the context in which a surface is embedded can influence its perceived lightness. Here we investigated whether similar contextual effects exist also for gloss perception by presenting single surfaces containing two different colors. We tested the influence of the second color on participants' gloss judgments with both real surfaces and photographs of those surfaces. In both conditions, participants were influenced by the second color on the surface even though they were asked to ignore it. We found contrasting contextual effects on the bicolored surfaces. However, when explicitly asked to rate the global gloss on the bicolored surfaces, participants took both parts of the surface equally into account.

摘要

光泽度这一物质属性在我们日常生活中许多物体上都有体现，从物理角度讲，它与物体颜色无关。然而，感知到的光泽度会随着高光与镜面高光周围区域之间的对比度而变化。迄今为止，实验主要研究的是单色表面的光泽。众所周知，表面所处的环境会影响其感知到的亮度。在此，我们通过展示包含两种不同颜色的单个表面，来研究光泽感知是否也存在类似的环境效应。我们用真实表面及其照片测试了第二种颜色对参与者光泽度判断的影响。在这两种情况下，尽管要求参与者忽略表面上的第二种颜色，但他们仍受到其影响。我们在双色表面上发现了对比鲜明的环境效应。然而，当明确要求参与者对双色表面的整体光泽度进行评分时，他们会平等地考虑表面的两个部分。
