A Simplified Model for the Rolling Shutter Based Camera in Optical Camera Communications

Abstract

A simplified model of the camera for optical camera communications (OCC) based on the rolling shutter effect is proposed and experimentally verified. In OCC, the key parameters are the exposure time, which is proportional to the DC gain and inversely proportional to the bandwidth, and the rolling shutter delay or the sampling period. We demonstrate a good agreement between experimental and numerically simulated results for the proposed receiver model.
