Abstract

La présente invention porte sur un procédé d'édition d'image destiné à fournir une interface d'édition d'image qu'un utilisateur peut facilement utiliser, et sur un appareil correspondant. Un appareil d'édition d'image selon la présente invention comprend : une unité d'affichage pour afficher une interface d'édition d'image comprenant une image à éditer et un outil d'édition ; un module de réglage de position pour identifier une section d'édition, dans laquelle un effet spécial est synthétisé, dans la totalité de la section de reproduction de l'image, sélectionner un nombre prédéterminé de scènes dans lesquelles un objet à effet spécial est exprimé dans la section d'édition et afficher les scènes sélectionnées sur l'unité d'affichage, et, lorsque l'objet à effet spécial est déplacé par un utilisateur dans les scènes affichées, reconfigurer la position de l'objet à effet spécial dans les scènes ; et un module de traitement d'effet spécial pour générer des données de détails d'édition dans lesquelles une position d'un objet à effet spécial dans chaque scène est incluse.
