Abstract: PURPOSE: An image encoding/decoding apparatus and a method thereof are provided to effectively predict an MV in the compression and encoding of an image. CONSTITUTION: In case the arbitrary MV(Motion Vector) of a current block is predicted within an image, an MV prediction unit(100) performs the prediction of the MV with at least one of the vector information of an MV corresponding to a peripheral block and the vector information of the previous MV of the current block. Difference decision units(201,202) decide difference information about the MV of the current block on the basis of the predicted MV and the actual MV of the current block.
