Adaptive sensing and image processing with a general-purpose pixel-parallel sensor/processor array integrated circuit

摘要

In this paper, a pixel-parallel image sensor/processor architecture with a fine-grain massively parallel SIMD analogue processor array is overviewed and the latest VLSI implementation, SCAMP-3 vision chip, comprising 128×128 array, fabricated in a 0.35μm CMOS technology, is presented. Examples of real-time image-processing executed on the chip are shown. Sensor-level data reduction, wide dynamic range and adaptive sensing algorithms, enabled by the sensor-processor integration, are discussed.
