PROBLEM TO BE SOLVED: To provide a structure of a small-sized camera capable of taking a clear image in 360° full-field video and recording it in a tube curved in a complicated manner, especially in a digestive organ of a living body, and also giving position reference information required for image processing.SOLUTION: A thinly cut image sensor is curled into a cylindrical shape having a smaller diameter than the inside diameter of a subject pipe and mounted, so that the inner pipe wall of the subject pipe can be imaged by circumferential scanning, and further reference information on the position required for composition of an accurate development elevation can be given jointly with image information from a full-field wide-angle lens.COPYRIGHT: (C)2014,JPO&INPIT【課題】複雑に彎曲した管内、特に生体の消化器官内において、鮮明な映像を360°全視野映像取込んで記録でき、且つ、画像処理に必要な位置参照情報も提供できる小型カメラの構造である。【解決手段】 本発明は、薄く切削されたイメージ・センサーを被験管の内径より細い円筒形に丸めて実装することにより、被験管の内管壁の円周走査撮像を可能にし、更に前視野の広角レンズから画像情報とあわせて、正確な展開図の合成に必要な位置の参照情報も提供可能である。【選択図】図1
