Effect of perceptually uniform color space and diversity of chromaticity components on digital signage and image sensor-based visible light communication

We study a visible light communication (VLC) system that modulates data signals by changing the color components of image contents on digital signage display, captures them with an sensor, and demodulates using processing. This requires modulated should not be perceived human eye. Previous studies have proposed modulation methods chromaticity component is difficult for eye to perceive, we also method perceptually uniform space based perception characteristics. However, which performs better depends contents, evaluation only some specific was sufficient. In this paper, evaluate visual quality various standard images clarify superiority space. addition, propose novel demodulation diversity combining eliminate dependency performance contents. Experimental results show can improve almost all images.
