Abstract

A 189 × 182 active pixel sensor for temporal difference computation is presented. The temporal difference imager, fabricated in AMI 0.5 μm process, contains in-pixel storage elements for previous and current frames. A pipelined architecture for difference readout is implemented, allowing >200 fps, 42 dB signal-to-noise ratio images and 8-bit precision of the difference image. The chip consumes 30 mW at 50 fps from 5 V power supply.
