VIDEO CODING METHOD AND DEVICE USING MOTION COMPENSATION WITHOUT MOTION VECTOR

摘要

PROBLEM TO BE SOLVED: To attain motion compensation without a motion vector. SOLUTION: Plural consecutive block images from Fn -th to Fn+1 -th order are received, intra-images (Fn -th and Fn+1 -th) are selected, the selected intra- images are subject to intra-image coding as a reference block image (Fn -th) and a predicted block image (Fn+1 th) to obtain a motion vector of the predicted block image. Then the distance between decoded intra-images is detected and an obtained motion vector is subject to interpolation processing to obtain a motion compensation image and a difference image between the motion compensation image and the received image is obtained. Then the difference image is coded and the image subject to intraimage coding and the coded difference image are obtained.
