METHODS FOR ENCODING/DECODING IMAGE AND APPARATUS FOR ENCODER/DECODER USING THE SAME

摘要

PURPOSE: An image encoding/decoding method and a device thereof are provided to reduce the bit numbers needed for encoding the division information of a target encoding block. CONSTITUTION: A decoder acquires the division information of a neighbor block to a target decoding block when the use of prediction division information is determined(S220,S230). The decoder predicts the division information of the target decoding block by an acquired neighbor block division information(S240). When the target decoding block is divided by the prediction division information, the decoder utilizes the prediction division information as the division information of the target decoding block(S250,S260).
