A method and an apparatus for image encoding/decoding are disclosed. The apparatus includes: a block decomposer for decomposing a current block into a plurality of sub-blocks; and an intra prediction encoder for performing an intra prediction encoding by referring to already encoded and decoded adjacent pixel information of each sub-block, based on an intra prediction mode equal to an intra prediction mode of the current block, thereby generating a bit stream for the current block. In image encoding and image decoding, when a current block to be encoded or decoded is predicted, the disclosed method and apparatus can improve the accuracy of the prediction, which can provide an image with a satisfactory reproduction quality by improved coding efficiency.
