CMOS Camera With In-Pixel Temporal Change Detection and ADC

Yu M. Chi, Udayan Mallik, Matthew A. Clapp, Edward Choi, Gert Cauwenberghs, Ralph Etienne-Cummings
2007 IEEE Journal of Solid-State Circuits  
Gating of raster-scanned pixel output by change detection typically produces a 20-fold compression in the data stream, depending on image conditions and reconstruction quality set by the change detection  ...  The chip, fabricated in a 0.5 m 3M2P CMOS, process consumes 4.2 mW of power while operating at 30 fps. Change sensitivity is 2.1% at an illumination of 1.7 W/cm 2 .  ...  In terms of scalability, the architecture scales well to larger sizes because the processing elements are distributed to the pixel and column levels and processed in a column parallel manner.  ...
