Abstract
A motion detecting device for enhancement of the image quality at ultra-low bit rates is disclosed, which permits quantization of the prediction error with the highest possible degree of accuracy, taking into account the amount of information which is generated by a motion vector generated by a motion vector generator. A difference vector corresponding to a difference between the motion vector and a motion vector of an already encoded reference pixel block located near the current pixel block to be encoded in said current frame is obtained. An output resulting from a motion detection of the difference vector so as to obtain the minimum step size from said difference vector, through the use of the number of generated bits and the number of bits of said difference vector, is encoded.
