摘要: 人眼对不同颜色的感知与辨别能力存在差异,容易导致观察到的画面中不同颜色亮色度均匀性效果不理想。本文针对人眼对不同颜色亮色度差异的敏感性顺序设计实验进行定量分析,并与通过CIE2000色差公式计算得到的理论结果进行对比,总结出人眼对不同颜色亮色度差异的敏感性顺序。从而可以将其应用到LED显示屏的生产过程中以及校正处理中,提高显示图像的质量。

Abstract:There are differences between different colors in perception and discrimination,it is easy to cause the color-difference uniformity unsatisfactory
of the observed images between different this paper,we conduct an experiment in order to carry out the quantitative analysis of human eye sensitivity to color-difference, compare with the theoretical results calculated from CIE2000 color-difference formula, then sum up the human eye sensitivity to color-difference. Thus,we can apply it to the production of LED display and correction processing for the sake of improving the quality of images.
Keywords: LED display color discrimination characteristics color-difference
