Abstract

This paper presents a dual-channel RAW and YUV image output CMOS image sensor (CIS) with high dynamic range (HDR) and LED flicker mitigation (LFM). To achieve a simplified system configuration, low-cost and low-power consumption, we implemented the data path and image signal processing (ISP) block which can generate the RAW and YUV data simultaneously. To achieve HDR and LFM, we implemented a sub-pixel architecture in the proposed CIS. With the dual-channel RAW and YUV image output CIS, the power consumption was reduced by 34.5% compared with a conventional system based on using two sensors, one for RAW and the other for YUV. In addition, it achieved dynamic range of 105dB (w/LFM) and 130dB (w/o LFM).
