项目摘要

"Area, effect of color" is the phenomenon that saturation and lightness of color appearance of a chromatic field will increase, as the area of the field becomes larger. The purpose of this research project is to understand characteristics of this area effect and investigate factors of the area effect of color.The first step we did in this research was "Quantification of Area Effect of Color." We exhibited a pair of chromatic fields in a single color as visual stimuli, those were equal colorimetrically, but area size was different. The observer adjusted a color of a small matching stimulus so that the color appearance of the matching stimulus became the same as a large test stimulus. As the result of matching task in each area size of test stimuli, we calculated the magnitude of area effect in lightness and saturation directions. In the result, increment of the lightness and saturation as the area effect was observed as expected. But we observed the dependency for hue in the area effect, and the area effect of red-green direction was stronger than blue direction.As the second step, we performed "examination of spatial characteristic of the area effect of color" to clarify factors of area effect. In this experiment, we divided the large test field to small color chips by dark lines. We performed the same experiment except using this stimulus. As the result, we found that the area effect decreased with the divided test stimulus. The hue dependency in the area effect observed in large test stimulus was also preserved, and the decline of the lightness and saturation increments was approximately proportional in all condition. It means that small color patches caught by fovea are insufficient to hold the area effect.It is required to perform the new experiment that will incorporate nonlinear space summation effect in modeling of the area effect in future.

“面积，颜色效应”是指当场的面积变大时，色场的颜色外观的饱和度和亮度将增加的现象。本研究的目的是了解这种面积效应的特点，并探讨影响颜色面积效应的因素，本研究的第一步是“颜色面积效应的量化”。“我们展示了一对单色的色场作为视觉刺激，它们在色度上是相等的，但面积大小不同。观察者调整小匹配刺激的颜色，使得匹配刺激的颜色外观变得与大测试刺激相同。作为匹配任务的结果，我们计算了在亮度和饱和度方向上的面积效应的大小。在结果中，如预期的那样观察到亮度和饱和度作为面积效应的增加。但是我们观察到面积效应中的色调依赖性，并且红绿方向的面积效应比蓝色方向的面积效应更强。作为第二步，我们进行了“颜色面积效应的空间特性检验”，以澄清面积效应的因素。在本实验中，我们用暗线将大测试场划分为小色片。我们进行了同样的实验，除了使用这种刺激。结果发现，面积效应随着测试刺激的分割而减弱。在大的测试刺激中观察到的面积效应中的色调依赖性也被保留，并且在所有条件下亮度和饱和度增量的下降近似成比例。这意味着由中央凹捕获的小色块不足以保持面积效应。未来需要进行将非线性空间总和效应纳入面积效应建模的新实验。
