摘要： A method and a device for encoding/decoding images are disclosed. The method for encoding images comprises the steps of: deriving a scan type of a residual signal for a current block according to whether or not the current block is a transform skip block; and applying the scan type to the residual signal for the current block, wherein the transform skip block is a block to which transform for the current block is not applied and is specified on the basis of information indicating whether or not transform for the current block is to be applied.

摘要： A method for decoding a video including a plurality of views, according to one embodiment of the present invention, comprises the steps of: configuring a base merge motion candidate list by using motion information of neighboring blocks and a time correspondence block of a current block; configuring an extended merge motion information list by using motion information of a depth information map and a video view different from the current block; and determining whether neighboring block motion information contained in the base merge motion candidate list is derived through view synthesis prediction.
