项目摘要

The purpose of this study was to analyze color mechanisms of human perception based on an integrative approach dealing with color adjustment, contrast and constancy as a whole, not treating them separately. A new instrument was required to display various colored figures of 2D and 3D on CRT in a simple operation. An Image Maker was obtained for this purpose in 1988. And we made other several instruments at our laboratories such as a measuring instrument of perceptual response, a switcher of pictures, interface devices, and so on. A visual stimulus presentation network system was completed as an organic unity consisted of picture memory, color monitor, the switcher which were controlled by a computer machine.New outcomes from this investigation, besides development of the network system that made possible to study various color phenomena in a simple way and to analyze complex pictures on CRT in terms of luminosity and chromaticity changing in time and space, were as follows :Mutual acti … More ons between rods and cones were a function of cones' activities with a short wavelength background. The result, revealed by the Psycho-Physical method, seemed to be important to understand a basic mechanism of human color perception in a transient process from photopic to scotopic states.To further investigate the physiological basis of color perception by Psycho-Physical methods, a typical property of the yellow-blue hue cancellation was measured and a hypothesis was proposed with a schematic diagram representing that the gain of the signal from the short-wavelength cones was assumed to be controlled by the difference in signals coming from the long- and middle-wavelength cones.In another study, we addressed the problem of what was the nature of information transformation of the red-green system. The results showed that the red-green opponent-color units with the center-surround receptive-fields organization was sufficient to transmit the achromatic and chromatic variables simultaneously.

本研究的目的是分析人类感知的颜色机制的基础上处理的颜色调节，对比度和恒定性作为一个整体，而不是单独对待他们的综合方法。需要一种新的仪器，以简单的操作在CRT上显示各种彩色的2D和3D图形。1988年为此目的获得了一台图像生成器。在实验室自行研制了知觉反应测试仪、图像切换器、接口设备等仪器，完成了由计算机控制的图像存储器、彩色显示器、图像切换器组成的有机整体的视觉刺激呈现网络系统。除了网络系统的发展，使用简单的方法研究各种颜色现象和用亮度和色度随时间和空间的变化分析CRT上的复杂图象成为可能外，还有如下因素： ...更多信息视杆细胞和视锥细胞之间的相互作用是视锥细胞在短波长背景下活动的函数。这一结果对于理解人类从明视到暗视的过渡过程中颜色知觉的基本机制具有重要意义，为了进一步从心理物理学的角度研究颜色知觉的生理基础，黄色的典型属性-测量了蓝色调消除，并提出了一个假设，其示意图表示来自短波长的信号的增益，在另一项研究中，我们讨论了红-绿系统信息转换的本质问题。结果表明，具有中心-环绕感受场结构的红绿双色单元足以同时传输消色差和彩色变量。少
