Reconfigurable hybrid event-based vision sensor and CMOS image sensor

Abstract

Reconfigurable hybrid event-based vision sensor and CMOS image sensor systems (an associated systems, devices, and methods) are disclosed. In one embodiment, a hybrid image sensor includes a pixel circuit array with pixel circuits reconfigurable between (i) a CMOS image sensor (CIS) configuration for obtaining intensity information and (ii) an event vision sensor (EVS) configuration for obtaining contrast information. Control circuitry can reconfigure a first subset of pixel circuits into the EVS configuration based on detected motion in an external scene, switching the hybrid image sensor between (a) a CIS-only mode in which all pixel circuits operate in the CIS configuration and (b) a hybrid mode in which the first subset operates in the EVS configuration and a second subset operates in the CIS configuration. The control circuitry can control the number of pixel circuits included in the first subset based on luminance conditions in the external scene.
