METHODS OF DECISION OF CANDIDATE BLOCK ON INTER PREDICTION AND APPRATUSES USING THE SAME

摘要

A method for deciding a candidate block when performing a prediction between screens and an apparatus using the same are disclosed. An image decoding method includes the following steps of: including a left lower second block in a merge candidate list in case the left lower second block is available; including a right upper second block in the merge candidate list in case the right upper second block is available; including a left lower first block in the merge candidate list in case the left lower first block is available; including the a right upper first block in the merge candidate list in case the right upper first block is available; including a left upper second block in the merge candidate list in case the left upper second block is available; and including a time candidate prediction block in the merge candidate block list in case the time candidate prediction block is available. Therefore, the present invention is able to increase encoding efficiency and reduce complexity.
