Abstract: Disclosed is a method of predicting a block vector in a multi-view image, the method including allowing an encoder to determine a reference block of a reference image for a specific block of a depth image or a specific-view image among multi-view images, allowing the encoder to determine block vector information for intra block copy (IBC) of the specific block on the basis of a block vector of the reference block when the reference block is encoded using the IBC, and allowing the encoder to encode the block vector information of the specific block. The reference image of the specific view is an image of another view, and the reference image of the depth image is a texture image corresponding to the depth image.
