Abstract

A device and method for detecting a motion vector of an image. The device comprises a horizontal edge extractor, a one-line accumulator, a delay register, a vertical line memory, a sign decision memory, a vertical correlation arithmetic unit, a horizontal edge extractor, a first horizontal line memory, a second horizontal line memory, a comparator, and a horizontal correlation arithmetic unit. Directional edges are used to enhance the accuracy of a motion vector. Since correlation values are calculated as soon as a scan is completed for a field image, it is possible to detect a motion vector at high speed. The device realizes a simple circuit by economizing memory.
