ABSTRACT:
There is provided a motion vector circuit for detecting screen shake of an image of an object. The circuit comprises a binary-coded edge portion signal generator for signal-processing a video signal corresponding to the image to generate a binary-coded edge portion signal including information of the edge portion of the image, a detector for delaying the binary-coded edge portion signal by a predetermined period of time to generate a delayed binary-coded edge portion signal so as to generate detection signals with time width corresponding to shake amount of the image by means of the binary-coded edge portion signal and the delayed binary-coded edge portion signal and a calculator for generating moving vector signals corresponding to the direction and the amount of the image by means of the detection signals to calculate the shake amount of the image by means of the moving vector signals and predetermined allowable deviation.
