Summary:An image decoding method is disclosed. An image decoding method according to the present invention may comprise the steps of: deriving initial motion information of the current block from at least one of motion information of a spatial neighboring block, motion information of a temporal neighboring block, and predefined motion information; generating corrected motion information by performing motion-information-correction on the initial motion information; and generating a prediction block of the current block by using the corrected motion information. La présente invention concerne un procédé de décodage d'image. Conformément à la présente invention, un procédé de décodage d'image peut comprendre les étapes consistant : à déduire des informations de mouvement initiales du bloc actuel à partir d'au moins une des informations de mouvement d'un bloc voisin spatial, des informations de mouvement d'un bloc voisin temporel, et des informations de mouvement prédéfinies ; à générer des informations de mouvement corrigées en réalisant une correction d'informations de mouvement sur les informations de mouvement initiales ; et à générer un bloc de prédiction du bloc actuel à l'aide des informations de mouvement corrigées. 영상 복호화 방법이 개시된다. 본 발명의 영상 복호화 방법은 공간적 주변 블록의 움직임 정보, 시간적 주변 블록의 움직임 정보 및 기정의된 움직임 정보 중 적어도 하나로부터 현재 블록의 초기 움직임 정보를 유도하는 단계; 상기 초기 움직임 정보에 움직임 정보 보정을 수행하여 보정된 움직임 정보를 생성하는 단계; 및 상기 보정된 움직임 정보를 이용하여 상기 현재 블록의 예측 블록을 생성하는 단계를 포함할 수 있다.
