用计算机VGA显示器复现指定颜色的研究

如能用计算机控制在普通ＶＧＡ显示器上准确地显示出指定的颜色，那么计算机显示系统就将成为色度学、彩色视觉、印刷、印染等领域方便的、价格低廉的研究手段，为此要对计算机显示系统的颜色空间进行标定，这时遇到的主要困难是显示器显示特性的非线性，以及Ｒ、Ｇ、Ｂ三个通道之间的交联作用，我们通过对几种不同瑾显示的研究，对Ｒ、Ｇ、Ｂ三角交联规律作了探索并提出了存在三色交联时的显示特性表示公式和参数标定方法，从而实现

Research on Reproduction of Specified Color with the Computer VGA Monitor

If we can reproduce the given colors accuately on a general computer VGA monitor,the computer display system will become a convenient and cheap tool for the research in the fields of chromatics,color vision,printing and dyeing.For this reason,the color space of computer display sysrem should be calibrated first.Meanwhile,the major difficulties are the nonlinear feature involved and the interaction among R,G and B channels of the display system.We investigated the tricolor interaction rules on several different models of monitors,then proposed the formula and parametric calibrating method so that given color can be displayed on VGA monitors without any need of human intervention.This will provide a good base for the widespread application of this approach- Experiments have proved that the approach proposed in this paper can substantially decrease the color difference between the given color and displayed color on screen to a degree acceptable for real use.
