MOVING DETECTING METHOD OF VIDEO SIGNAL

摘要

PURPOSE:To detect a dynamic picture area in a remarked frame more faithfully by considering a comparison frame to be not only a frame just before the remarked frame but plural frames before and after the remarked frame. CONSTITUTION:An area which is common to three or more frames among four frames detected by correlation calculation between the remarked frame N and the comparison frames N+ or -1 and N+ or -2 apart from the remarked frame N by + or -1 frame and + or -2 frames in the meaning of time is made to be the dynamic picture area of the remarked frame. Thus, possibility to detect the dynamic area of the remarked frame as mistaking it for the still picture area can be made extremely low.
