The applications, in battery-limited environments, can profit from an event-driven approach for moving-object detection. This paper presents a 1/4-inch 3.9Mpixel low-power event-driven back-illuminated stacked CMOS image sensor (CIS) deployed with a pixel readout circuit that detects moving objects for each pixel under lighting conditions ranging from 1 to 64000lux. Utilizing pixel summation in a shared floating diffusion (FD) for each pixel block, moving object detection is realized at 10 frames per second while consuming only 1.1mW, a 99% reduction in power from the same CIS at a full-resolution 60 frame per second power of 95mW. |
