Abstract
Signals generated by an array of photodiodes are applied to the inputs of corresponding edge detection circuits. Each edge detection circuit generates an output that changes state in response to a detected edge of the photodiode generated signal. The edge detection circuits may be formed by toggle flip-flop circuits. The outputs of the edge detection circuits are logically combined using exclusive OR logic to generate an output. The exclusive OR logic may be formed by a cascaded tree of exclusive OR circuits.
