(EN) METHOD AND DEVICE FOR PRESENTING VIDEO CONTENT
(FR) PROCEDE ET DISPOSITIF DE PRESENTATION DE CONTENU VIDEO

Abstract
(EN) A method for presenting a video content by extracting two or more key images contained in each scene from a video including at least a moving picture and dividable into scenes and constructing a digest image of the video including the key images. The method is characterized by comprising a scene dividing step of dividing a video into scenes and three steps for each scene: a key image extracting step, a preceding/succeeding key image extracting step of extracting at least one still image preceding and/or succeeding the key image in time series, and a key image weighting step of performing weighting of the key images concerning a predetermined criterion, and by further comprising an image constructing step of arranging the preceding/succeeding key images near and adjacent to the key image and constructing a digest image by turning on/off the display and enlarging/reducing the key image according to the weight, and an image display step of displaying the digest image.
(FR) Cette invention concerne un procédé de présentation de contenus vidéo consistant à extraire deux ou plusieurs images clés contenues dans chaque scène d'un enregistrement vidéo comprenant au moins une image mobile divisible en scènes, et à construire une image condensée de l'enregistrement vidéo contenant les images clés. Ce procédé se caractérise en ce qu'il consiste à diviser un enregistrement vidéo en scènes avec pour chaque scène trois opérations - extraction d'une image clé; extraction d'au moins une image fixe précédant/suivant l'image clé dans la séquence temporelle à pondérer des images clés en fonction d'un critère prédéterminé, puis à construire une image en agençant les images précédant/suivant les images clés proches ou adjacentes de l'image clé, à construire une image condensée par coupure/fermeture de l'affichage et élargissement/réduction de l'image clé en fonction de la pondération, et à afficher l'image condensée.
(JA) 本発明は少なくとも動画像を含み、複数のシーンに分割可能な映像から、各シーンに含まれる2画像以上のキー画像群を抽出し、該キー画像群を含む当該映像のダイジェスト画面を構成する映像内容の提示方法である。本方法は、シーン毎に分割するシーン分割ステップ、各シーンについてキー画像抽出ステップ、キー画像の時系列で前及び/又は後の少なくとも1静止画像を抽出する前後キー画像抽出ステップ、キー画像に対して所定の尺度に係る重み付けを行うキー画像重み付けステップの3ステップを行うと共に、キー画像の隣接した近傍に前後キー画像を配置し、かつキー画像を重みに応じて表示・非表示の切替や拡大縮小してダイジェスト画面を構成する画面構成ステップ、ダイジェスト画面を表示する画面表示ステップを少なくとも有することを特徴とする。
