Abstract
A scheme for digitizing a stationary video image is disclosed. The amplitude of a video signal, representing said video image, is sampled at a plurality of points along the time axis and is compared with the count in a counter. If the amplitude equals the count at a particular point on the time axis, the count is stored in a memory in a location corresponding to said particular point. The process is repeated until a count in the counter is stored in said memory in locations corresponding to all of said plurality of points along the time axis of said video signal. If two or more counters are used, each counting from a different initial value, and if two or more corresponding comparators are used to make the above comparison, the time required to digitize said stationary video image may be reduced. Consequently, the time required for the video image to remain stationary is reduced.
