Abstract

A 1.4Mpixel CMOS image sensor (CIS) with multiple row-rescan (MRR) based data sampling for optical camera communication (OCC) is presented. The CIS achieves a data sampling rate at a row-scan rate of 51kS/s even with a frame rate of 30fps, a pixel size of 2.2mm × 2.2mm by multiply rescanning the rows at a modulated LED spot. The detectable minimum LED size projected onto the CIS becomes 13.2mm × 13.2mm. The MRR could be a practical solution for IEEE 802.15.SG7a OCC.
