This paper presents a black-sun immune correlated double sampling (CDS) scheme for high-quality imaging. Based on an analysis of signal characteristics in strong light conditions, a clamping circuit-based signal difference generator is proposed to accurately present the bright light information. The proposed scheme eliminates the black-sun noise with simple circuitry to improve the A/D conversion efficiency. Moreover, it can be is reversible to the conventional algorithm so that it stilldoi:10.1587/elex.18.20210175 fatcat:qqav3cfe7rauvcxxe2ztenzmz4
