<p>A motion vector coding unit (117) performs a peripheral block specifying step (S100) of specifying a peripheral block around a block to be coded, determining steps (S102 and S104) of determining whether the peripheral block is coded by using a motion vector of other blocks, prediction steps (S106 and S108) of deriving predicted value of the motion vector of the block to be coded by using the motion vector obtained from the motion vector of the other block as the motion vector of the peripheral block, and a coding step (S110) of coding the motion vector of the block to be coded by using the predicted value.</p> |
