Digital signage, which is advertising media by liquid crystal display (LCD), is expanded into many scenes. The digital signage can use digital techniques, and has a possibility of a lot of applications. As an application, it is desired to realize, wireless communications between the digital signage and viewers. In this study, we focus on the image-sensor-base visible light communication (ISVLC). ISVLC needs only an image sensor (IS), which is prevalent equipment of smart phone, and LCD since it can solve the cost problem of introduction of wireless communications. In ISVLC, the digital signage displays information signal on LCD. Therefore there is an issue, in which the information signal embedding in signage images decreases the quality of signage images. In this study, we propose blue color difference modulation, which makes imperceptible signal. By the construction of ISVLC system between digital signage and IS, we show the effect of the proposal modulation in real environment. |
