Influence of ipRGC Illuminance on Image Visual Effect and Visual Comfort
The novel photoreceptor cell ipRGC discovered at the beginning of this century not only participates in the regulation of non-visual effects such as circadian rhythms,but also has a regulatory effect on visual effects.However,the influence of ipRGC on image vis-ual effect is unclear.Existing display systems are designed based on the characteristics of cone cells.It is of great significance for the development of image processing technology and the improvement of display quality to evaluate the influence of ipRGC.A multi-primary color display system is built,which can independently control the ipRGC illuminance,and produce the metameric images with different ipRGC illuminance.The results show that increasing the ipRGC illuminance enhances the perceived brightness,and high ipRGC illumi-nance is beneficial to reduce the visual discomfort caused by viewing images.
