项目摘要

It has been said that an aged person observes everything yellowish because his lens in the eyeball becomes yellow. I intended to measure the color visual MTF properties of the aged person using a computer display under the financial help of Grand-in-aid for scientific research. The patterns used for the measurement must have no luminance difference but only color (hue) difference. However, if color changes, luminance also changes subordinately. In this paper, luminance is defined as brightness measured by an instrument. On the contrary, brighten sensation of human being is defined brightness. In advance of development color design, luminance of an instrument was confirmed as almost same as brightness of human being by flicker method. Then, in this investigation the luminance was used for speculation. It means color and brightness are determined by calculations. This investigation presents how to design the various colors keeping uniform luminance in a pattern. First method is that defaults values : R (red), G (Green) and B (Blue) in a computer, are initially determined, and then calculate color coordinates under keeping same luminance. Second method is that the most desirable color (color coordinates) are determined, consequently, the defaults values of R, G and B are calculated under the keeping same luminance.Using these determined colors, color MTF propensities were measured for an aged person in comparison with young subjects and concluded that there is no different in color vision among them.

有人说，老年人观察到的一切都是黄色的，因为他眼球中的透镜变黄了。本课题是在科学研究资助下，利用计算机显示器测量老年人的彩色视觉MTF特性。用于测量的图案必须没有亮度差异，只有颜色（色调）差异。然而，如果颜色改变，亮度也随之改变。本文将亮度定义为用仪器测量的亮度。相反，人类的明亮感觉被定义为亮度。在开发色彩设计之前，通过闪烁法确定仪器的亮度与人的亮度几乎相同。然后，在该调查中，亮度用于推测。这意味着颜色和亮度是由计算决定的。本研究提出如何设计各种颜色保持均匀的亮度在一个模式。第一种方法是先确定计算机中的默认值：R（红色）、G（绿色）和B（蓝色），然后在保持亮度不变的情况下计算颜色坐标。第二种方法是确定最理想的颜色（色坐标），然后在保持相同亮度的情况下，计算R、G和B的默认值，用这些确定的颜色测量老年人和年轻人的颜色MTF倾向，得出老年人和年轻人的色觉没有差异的结论。
