Abstract

This article presents a 0.56/0.8 V multimode vision sensor for temporal and spatial information extraction with processing in sensor (PIS) technique. The proposed six tran- sistors and one capacitor (6T1C) temporal contrast pixel (TCP) structure using the exposure compensation scheme (ECS) can realize in-pixel temporal contrast calculation and motion event reporting (ER) with global shutter exposure and seamless frame difference (FD) based on the pulsewidth modulation (PWM) operation.
