Abstract: PURPOSE: A coding mode determining method and an apparatus thereof are provided to skip an intra prediction process or an intra coding process about a current block according to the satisfaction of a condition, thereby reducing the complexity of an encoding device. CONSTITUTION: An encoding device determines whether intra prediction about a current block is skipped or not. In case the intra prediction is determined to be skipped, the encoding device determines coding modes except an intra mode from all coding modes of the current block as multiple coding mode candidates. The encoding device determines a corresponding coding mode among the coding mode candidates and encodes the current block by performing a rate distortion optimization (RDO) process about the coding mode candidates (S310,S320). [Reference numerals] (S310) Determine a decoding module of a current block; (S320) Conduct a decoding of the current block
