不同年龄段人眼的视觉感知研究

为了探究不同年龄段人眼的视觉特性, 采用立体色域的方法建立了显示系统中不同年龄人群的视觉感知模型, 以基于CIEL*A*B*颜色空间的立体色域作为标准, 取得了不同年龄观察者的立体色域数据。结果表明, 从光度学来看, 观察者年龄的增长会导致其明视光谱发光效率函数的峰值响应有小幅度的降低, 并且其峰值位置在波长轴上向长波方向移动; 从色度学上来看, 色域体积从20岁的1.73×106到60岁的1.16×106, 减小了约1/3, 且这种减小集中在中高亮度水平上; 进一步分析波长与立体色域的关系, 发现绿色光源对所有年龄观察者的立体色域影响最大, 对于所有的观察者推荐520 nm的最佳波长选择。该研究可为显示系统针对不同年龄观察者的色域、波长和亮度之间提供设计指导。

Abstract

In order to explore the visual characteristics for different ages, the method of stereo color gamut was used to establish the visual perception model for different ages in the display system. Taking the stereo color gamut based on the CIEL*A*B* color space as the standard, stereo gamut data was obtained for different age observers. The results show that from the photometric point of view, the increase of age will lead to a small decrease in the peak response of the photopic spectral luminous efficiency function, and the peak position moves to the long wavelength on the wavelength axis; from the chromaticity point of view, the color gamut volume is reduced by about 1/3 from 1.73×106 in 20-years-old to 1.16×106 in 60-years-old, and this reduction is concentrated in the middle and high brightness planes. Further analysis of the relationship between wavelength and stereo color gamut, the green light source is found to have the greatest effect on the stereo color gamut for all age observers, and the optimal wavelength selection is recommended 520 nm for all observers. The research can provide design guidance between the color gamut, wavelength and brightness of display systems for different age observers.
