A DSP‐like analogue processing unit for smart image sensors

Abstract

Abstract An electronic retina featuring DSP‐like programmable analogue processing is addressed. The motivations for designing such an original smart image sensor are accounted for. The architecture of the circuit is described and then the two more important building blocks are detailed. Finally, the practical implementation and tests results are given so as to validate the approach. Copyright © 2002 John Wiley & Sons, Ltd.
