摘要： Disclosed are an image encoding method using a skip mode and a device using the method. The image encoding method may comprise the steps of: judging whether there is residual block data of a prediction target block on the basis of predetermined data indicating whether residual block data has been encoded; and, if there is residual block data, restoring the prediction target block on the basis of the residual block data and an intra-screen predictive value of the prediction target block. Consequently, encoding and decoding efficiency can be increased by carrying out the encoding and decoding of screen residual data only for prediction target blocks where there is a need for a residual data block in accordance with screen similarity.

摘要： 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.

摘要： Disclosed are a video encoding/decoding method and apparatus including a plurality of views. The video decoding method including the plurality of views comprises the steps of: inducing basic combination motion candidates for a current Prediction Unit (PU) to configure a combination motion candidate list; inducing expanded combination motion candidates for the current PU when the current PU corresponds to a depth information map or a dependent view; and adding the expanded combination motion candidates to the combination motion candidate list.
