Abstract:

This paper presents a CMOS image sensor (CIS) that integrates two operation modes: a high-resolution viewing mode with 0.8μm 32 Mpixels and a low-power always-on object recognition mode consuming 2.67 mW at 10 fps. The CIS features a unique windmill-pattern analog edge extraction circuit that is resilient to illumination variations. An on-chip deep …
