PURPOSE: A motion estimating method and apparatus are provided to obtain a fast convergence time and an exact motion vector. CONSTITUTION: A motion vector storage section(501) stores a motion vector with respect to each block of a previous frame and a motion vector of a block a motion vector of which is previously calculated among blocks of a current frame. A motion vector output section(502) outputs from a motion vector having a high priority order in motion vectors output from the motion vector storage section(501). A priority order information calculator(503) determines a priority order of the motion vectors. A candidate vector selector(504) selects (K+1) different candidate vectors from the motion vectors from the motion vector output section(502). A motion vector determining section(505) determines a vector which minimizes an estimate function among the (K+1) different candidate vectors as a motion vector of a current block. |
