Abstract: An image encoding/decoding method and apparatus is provided. The method of decoding an image includes decoding at least one of prediction mode information of a neighbor block of a current block and length information of the current block, deriving an intra prediction mode of the current block into a predetermined mode using the decoded information, and reconstructing the current block based on the intra prediction mode of the current block.

Abstract: The present invention relates to a video encoding/decoding method and apparatus, and more particularly, to a method and apparatus for generating a reference image for a multiview video. The video encoding method includes, in the presence of a second image having a different view from a first image having a first view, transforming the second image to have the first view, generating a reference image by adding the second image to a side of the first image, and storing the reference image in a reference picture list.
