Color Appearance Mode studied based on Recognized Visual Space of Illumination

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，这个颜色模式问题还没有很好的解释。在本文中，我们引入了一个概念的识别视觉空间的照明，R，并解释了颜色模式，在这样一种方式，表面出现光源颜色时，表面的照度超过R的大小。在第一个实验中，局部照明的阈值方法被用来显示的大小R的变化，根据照度水平的空间。其次，通过增加被试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。当窗口逐渐打开时，色卡的颜色逐渐变化，显示出R随着初始视觉信息的增加而逐渐增长。然后再次通过测量放置在测试室中窗户外的色卡的颜色外观来研究两个R之间的相互关系。当观察者房间的照度相对于测试房间的照度适当调节时，两个空间之间存在连续性感知。当受试者房间为室内房间，测试房间为室外时，当受试者房间的照度约为室外照度的十分之一时，可实现连续性。

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.
