- 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.
