Abstract
A system for computer vision in association with a computer comprises a solid state image sensor or optic ram, a lens, a clock circuit for sequentially addressing the image sensor, and an edge detect circuit for detecting edges in the output bit stream of the image sensor. The edge detect circuit generates an interrupt signal for application to the clock circuit to stop the clock from advancing the addresses and for application to the computer to signal it to read the column and row address currently generated by the clock circuit.
