A METHOD AND APPARATUS FOR ENCODING AND DECODING IMAGE USING ADAPTIVE SEARCH RANGE DECISION FOR MOTION ESTIMATION

摘要

Disclosed are an encoding and decoding method and an encoding and decoding apparatus. When a current frame including a current block is a P frame, a motion vector and an intra-mode-to-inter mode ratio of a frame encoded and decoded previously to the current frame are analyzed in order to determine a temporal search range and a spatial search range of a reference frame.
