  Abstract

In this paper, we propose Optical Camera Communication (OCC), which is one of the VLC techniques, with RGB LEDs and Rolling Shutter effect. As conventional VLC uses photo diode to implement a receiver, additional devices are required. The VLC technique we propose, in this paper, uses optical camera embedded in smart phone. As smart phones are used by most people, additional devices are not required to implement a receiver. Rolling Shutter effect from Complementary Metal Oxide Semiconductor (CMOS) cameras embedded in smart phones makes time interval between pixels during making an image, and in the mean time, we can implement data transmission. And we expand transmission capacity by implementing MIMO through RGB LEDs. we propose the way for improving communication performance by applying Histogram Equalization and verify the performance by test.
