To provide a method for increasing accuracy in judgment between frame coding and field coding without increasing the processing amount of motion compensation. The frame coding or field coding judging method includes specifying, in a reference picture, a corresponding block which corresponds to a current block to be coded, obtaining a judgment indicator based on the specified corresponding block, and judging the coding method for the current block to be coded by judging one of frame coding and field coding to be appropriate as the coding method for the current block according to the obtained judgment indicator.
