Abstract
Abstract Circuitry senses a particular pattern or indicia in the output of a video camera to produce a pulse indicative of the position of the pattern. A control circuit senses the time of the pulse relative to respective horizontal and vertical control pulses to drive a positioning mechanism to position the pattern or indicia in accordance with the horizontal and vertical controlling pulses.
