Abstract
A dual-tap coded-exposure-pixel (CEP) image sensor is presented and demonstrated in several computational imaging applications. The NMOS-only data-memory pixel (DMP) reduces transistor count in CEP yielding 39,000 subexposures/s at 320x320 sensor resolution with 7 µm pitch. The outputs of a frame-rate 12-bit ADC1 and a 1-bit subexposure-rate ADC2 are adaptively combined to boost the native dynamic range of coded-imaging modalities by over 57dB, demonstrating over 101dB dynamic range in intensity imaging. The CEP camera combined with machine learnt projection patterns enables single-shot structured-light 3D imaging at native resolution and video rate.
