Claim 0:
1. A multi-view image decoder using intra block copy (IBC), the multi-view image decoder comprising:
an input device configured to receive a bitstream for multi-view images;
a storage device configured to store a program for performing IBC-based intra-prediction; and
a computing device configured to extract block vector information for a specific block from the bitstream, determine a reference block used to encode the specific block using the block vector information, and decode the specific block using the reference block,
wherein in response to the specific block being a first specific block of first specific-view image in the multi-view images, the computing device is configured to decode the first specific block of the first specific-view image on the basis of a first reference block of a reference image that has been coded in the multi-view images; and
wherein in response to the specific block being a second specific block of a first layered image of second specific view image in the multi-view images, the computing device is configured to decode the second specific block of the second specific view image on the basis of a second reference block of a second layered image which corresponds to the second specific block of the first layered image,
wherein when the first reference block is encoded using the IBC,
the block vector information comprises at least one piece of information in an information group including a first block vector of the first specific block, a second block vector of the first reference block, and a difference between the first block vector and the second block vector, and
the computing device determines the first reference block in the reference image using the at least one piece of information.
