Abstract
An apparatus for to extracting a video signal corresponding to a moving object in a video signal representing moving and stationary object comprises means for detecting a contour in the video signal and storing the contour data of successive frame in two frame buffers. Contour data stored in the two frame buffers are compared with each other so that a transition between corresponding portions of the two frame buffers are detected. This transition image is also stored in another memory and additional pixel transitions are interpolated at pixels having adjacent transitions. Thereafter, an area encompassed by the pixels representing the transition is combined with the video signal so that a motion video signal can be extracted.
