Paper Abstract

The design and implementation of a smart image sensor to provide high dynamic range and pixel level digital image processing is described. In this article we investigate important issues in the development of digital intelligent pixel CMOS image sensors. We have developed a high density imager with pixel level stochastic arithmetic and a high dynamic range exceeding 90 db. The ASIC prototype named PIKASSO includes a 96×64 pixel array, each pixel has a fill factor of 15% in an area of 29×29 μm2. The average power consumption per pixel at a frequency of 150 kHz is 78 μW.
