PURPOSE: An image encoder and a method thereof which encodes/decodes an adaptive motion vector are provided to adaptively determine accuracy of a motion vector and to encode the motion vector. CONSTITUTION: An intra prediction unit(102) generates a prediction block about a current block by using a pixel value. An inter prediction unit(103) generates the prediction block about the current block by using previously encoding and decoded pictures. An adder(112) restores the current block. A MV(Motion Vector) encoding unit(106) encodes the motion vector. An entropy encoding unit(107) encodes a quantized conversion block. |
