Abstract
(EN)
A partial image acquisition unit 50 of an image data output device 10 acquires a plurality of partial images that have been photographed at different angles of view. An output image generation unit 52 generates data of a single wide-angle image by connecting partial images. A map generation unit 56 generates map data concerning joints between the partial images, while a data output unit 54 outputs the respective data. A content creation device 18 refers to the map data, enlarges an area including a joint, and detect and correct an image distortion or a non-continuous portion. A content reproduction device 20 refers to the map data, connects and combines, as appropriate, the rest of the partial images, and outputs the resultant image to a display device 16b.

Selon l'invention, une unité d'acquisition d'image partielle 50 d'un dispositif de délivrance de données d'image 10 acquiert une pluralité d'images partielles qui ont été photographiées selon différents angles de champ. Une unité de génération d'image de sortie 52 génère des données d'une image grand-angle unique par liaison d'images partielles. Une unité de génération de carte 56 génère des données de carte concernant des jointures entre les images partielles, tandis qu'une unité de délivrance de données 54 délivre les données respectives. Un dispositif de création de contenu 18 consulte les données de carte, agrandit une zone comprenant une jointure, et détecte et corrige une distorsion d'image ou une partie non continue. Un dispositif de reproduction de contenu 20 consulte les données de carte, relie et combine, le cas échéant, le reste des images partielles, et délivre l'image résultante à un dispositif d'affichage 16b.

画像データ出力装置10の部分画像取得部50は、異なる画角で撮影された複数の部分画像を取得する。出力画像生成部52は部分画像を接続して1つの広角画像のデータを生成する。マップ生成部56は部分画像のつなぎ目に係るマップデータを生成し、データ出力部54はそれらのデータを出力する。コンテンツ作成装置18は、マップデータを参照してつなぎ目を含む領域を拡大し、像の歪みや不連続な箇所を検出して修正する。コンテンツ再生装置20はマップデータを参照して、残りの部分画像を適宜接続、合成して表示装置16bに出力する。
