This article describes a 30 frames/second VGA-format CMOS image sensor with an
embedded massively parallel processor. The processor is fully programmable
and therefore the sensor IC itself is able to run a variety of algorithms
within close data vicinity of the sensor. Because of the parallel
processor array and parallel memory accesses,
high computational performances of up to 5 GOPS are achieved.
This high performance allowed us to implement skin tone detection on the
camera itself as part of a larger system for face recognition, releasing
the host computer of cumbersome pixel processing tasks and minimizing the
data transfer between camera and computer.
