Motion correction apparatus for image and method thereof

PURPOSE: An apparatus and a method for correcting shifting of an image are provided to improve compression efficiency of video signals in a video processing system by considering the correlation between the frames. CONSTITUTION: An apparatus for correcting motion of an image includes a frame memory(102) and a motion estimation and correction device(110). The frame memory stores an input of video signal as a current frame image. The motion estimation and correction device estimates motion with respect to a previous frame image on the basis of image regions included in a predetermined motion estimation range in the current frame image to detect an image region to be compressed. The motion estimation and correction device provides the detected image region as an image region of the current frame for normal motion estimation to correct motion of the image.
