项目摘要

There are two typical appearance of color, namely object color and light source color. There were no good explanation for this color mode problem so far. In this paper we introduced a notion of the Recognized Visual Space of Illumination, R,and the color mode was explained in such a way that a surface appears as light source color when the illuminance of the surface exceeds the size of R.In the first experiment the threshold method of local illumination was used to show the size of R changes according to the illuminance level of the space. Secondly, the formation process of R was investigated by increasing the initial visual information of a space which a subject observes through a window of which size is adjustable. Color of color chips gradually changed when the window was gradually opened to show a gradual growth of R with increase of the initial visual information. Interrelation between the two Rs was then investigated, again, by measuring color appearance of color chips placed in a test room beyond the window. There existed a continuity perception between the two spaces when the illuminace of the observer's room was properly adjusted relative to the illuminance of the test room. The conitnutiy was achieved, when the subject's room was a room inside a house and the test room was outside, when the illuminance of the subject's room was about one tenth of the outside.

颜色有两种典型的表现形式，即物体颜色和光源颜色。到目前为止，对于这个颜色模式问题还没有很好的解释。本文引入了可识别的视觉照度空间R的概念，并解释了这种颜色模式，即当表面的照度超过R的大小时，表面显示为光源颜色。在第一个实验中，使用局部照度的阈值方法来显示R的大小随空间照度的变化。其次，通过增加受试者通过大小可调的窗口观察到的空间的初始视觉信息来研究R的形成过程。随着窗口的逐渐打开，色卡的颜色逐渐改变，呈现出随着初始视觉信息的增加而逐渐增长的R。然后，通过测量放置在窗外测试室中的色卡的颜色外观，再次研究了两个R之间的相互关系。当观察者房间的照度相对于测试室的照度适当调整时，两个空间之间存在着一种连续性的感觉。当受试者的房间是房子里的一个房间，而测试室在外面时，当受试者的房间的照度大约是外面的十分之一时，这种连续性就实现了。
