<p>A motion vector coding apparatus includes a motion vector generation unit configured to generate a motion vector of a coding target block in a coding target color plane, an inter-plane motion vector extraction unit configured to extract a motion vector of an inter-plane reference block which is a block in a color plane different from the coding target color plane and at the same position as that of the coding target block; a predicted motion vector calculation unit configured to calculate a predicted motion vector from the motion vector of the inter-plane reference block, a motion vector error calculation unit configured to calculate a motion vector error from the motion vector of the coding target block and the predicted motion vector, and a motion vector difference coding unit configured to code the motion vector error.</p> |
