Abstract: Provided are an image encoding method and device. When carrying out image encoding for a block within a slice, at least one block in a restored block of the slice is set as a reference block. When this is done, the encoding parameters of the reference block are distinguished, and the block to be encoded is encoded adaptively based on the encoding parameters.

Abstract: An image encoding/decoding method is disclosed. An image decoding method of the present invention may comprise identifying a region by partitioning an image, and determining a prediction mode of the region on the basis of at least one of a size of the region, a partition shape, and a coding parameter of the region. The determined prediction mode of the region may be determined as a prediction mode of all coding blocks included in the region.

Abstract: An image encoding/decoding method and apparatus are provided. An image decoding method performed by an image decoding apparatus of the present invention may comprise decoding an indicator indicating whether or not partition information of a current block is derived from partition information of a corresponding block of the current block, obtaining the partition information of the current block based on the decoded indicator, and partitioning the current block based on the obtained partition information.
