Claim 1:
2. The method of claim 1, wherein,
taking an initial motion vector as a center, selecting motion vectors from the motion vectors containing the initial motion vector and the motion vectors surrounding the initial motion vector, and determining the selected motion vectors as candidate motion vectors, comprises: taking the initial motion vector as a center, searching 25 motion vectors containing the initial motion vector at a search range of 2, and determining the 25 motion vectors as candidate motion vectors; wherein a searching sequence of the 25 motion vectors is as follows: {Mv(−2,−2), Mv(−1,−2), Mv(0,−2), Mv(1,−2), Mv(2,−2), Mv(−2,−1), Mv(−1,−1), Mv(0,−1), Mv(1,−1), Mv(2,−1), Mv(−2,0), Mv(−1,0), Mv(0,0), Mv(1,0), Mv(2,0), Mv(−2,1), Mv(−1,1), Mv(0,1), Mv(1,1), Mv(2,1), Mv(−2,2), Mv(−1,2), Mv(0,2), Mv(1,2), Mv(2,2)}.
