| Summary |
In digital signage and image sensor-based visible light communication, a LED-backlight display (digital signage) is used as a transmitter and a hand-held camera (image sensor) device is used as a receiver. Data signals are embedded on image contents projected by the digital signage and sent to the receiver by visible light communication. In this system, there is a problem that embedded data signals may be perceived by human eyes as the degradation of visual quality. To realize a visible light communication system that is difficult to be perceived, we propose a data signal modulation scheme based on a color space considering human color perception, and show that the proposed scheme has better visual and communication quality compared to the conventional scheme. |
