Abstract
Differential binary pixel technology is a threshold-based timing, readout, and image reconstruction method that utilizes the subframe partial charge transfer technique in a standard four-transistor (4T) pixel CMOS image sensor to achieve a high dynamic range video with stop motion. This technology improves low light signal-to-noise ratio (SNR) by up to 21 dB. The method is verified in silicon using a Taiwan Semiconductor Manufacturing Company’s 65 nm 1.1  μm pixel technology 1 megapixel test chip array and is compared with a traditional 4  ×   oversampling technique using full charge transfer to show low light SNR superiority of the presented technology.
