Abstract

One embodiment of the present invention relates to a method and an apparatus for encoding/decoding an image using effective in-screen prediction mode group selection. One embodiment of the present invention relates to a method and an apparatus for encoding/decoding an image, comprising a step for selecting an intra-prediction mode set using the pixels of peripheral blocks of a current block, and a step for generating a predicted block in one prediction mode of the selected intra-prediction mode set, thereby improving compression capability.
