Summary:To provide an encoding device for efficiently encoding a motion vector of an image to be hierarchically encoded and a decoding device.SOLUTION: When there are motion vectors of blocks in images on different layers that are in positions corresponding to the blocks to be encoded, the motion vectors of a time-pre-encoded image of the same layer are not included in predicted motion vector candidates, the motion vectors of the different layers are placed at a beginning of the predicted motion vector candidates, and motion vectors of surrounding blocks of the block to be encoded are placed as candidates in order based on the position of the blocks.SELECTED DRAWING: None 【課題】階層符号化する画像の動きベクトルを効率的に符号化する符号化装置、復号装置を提供する。【解決手段】異なるレイヤにおける画像に含まれ符号化対象ブロックに対応する位置にあるブロックの動きベクトルが存在する場合に、同じレイヤの時間的に前に符号化された画像の動きベクトルを予測動きベクトル候補に含めず、異なるレイヤの動きベクトルを予測動きベクトル候補の先頭に配置し、符号化対象ブロックの周辺ブロックの動きベクトルをブロックの位置に基づいて順番に候補として配置する。【選択図】なし
