Paper Abstract

CMOS technology, as a popular VLSI technology, is very attractive for achieving `smart' vision devices. This paper introduces two high integration CMOS vision chips, fabricated using unmodified commodity 0.8 micrometers CMOS process, with the resolution of 369 X 287 and 768 X 574. In addition to a photodiode array, two devices include all necessary circuits to drive and sense the array, as well as TV signal formatting and other control functions. On-chip automatic exposure control enables the use of a fixed- aperture lens. On-chip automatic gain control improves dark pictures and on-chip black-calibration maintains image stability. The miniature cameras using the chips enjoy great reductions in size, cost, and power consumption.
