Abstract

An apparatus includes a video sensing device, a velocity vector estimator (VVE) coupled to the video sensing device, a controller coupled to the velocity vector estimator, and an orthogonal transfer charge-coupled device (OTCCD) coupled to the controller. The video sensing device transmits a plurality of image frames to the velocity vector estimator. The controller receives a location of an object in a current frame, stores locations of the object in one or more previous frames, predicts a motion trajectory and the predicted location of the object on it in a subsequent frame as a function of the locations of the object in the current frame and the one or more previous frames, and transmits the predicted location of the object to the OTCCD. The OTCCD shifts its image array of pixels as a function of the predicted location of the object.
