Description
以下、図を参照して実施の形態1の構成について説明する。本実施の形態にかかる記録再生装置10は、移動体である自動車等の車両に設置して用いられ、カメラが撮影した撮影データを記録および再生するものであって、例えばドライブレコーダと呼ばれる装置である。記録再生装置10は、突発的な衝撃などが加えられた場合に加えられた衝撃をトリガとして、予め設定された期間分の撮影データを「イベント記録データ」として再生可能に記録する機能を有している。自動車の運転者等は、このイベント記録データを再生し、再生したイベント記録データの映像を見ることによりイベントの状況を把握できる。
次に実施の形態1の変形例について説明する。実施の形態1の変形例にかかる記録再生装置は、撮影データを生成するカメラ150および撮影データ取得部120を少なくとも有する記録装置と、視線検出カメラ151および表示部141を少なくとも有する再生装置とが分離して存在している。
次に、実施の形態2について説明する。実施の形態2にかかる記録再生装置は、イベント記録データを再生する処理において、視線検出部130の機能が実施の形態1と異なる。実施の形態2にかかる記録再生装置10において、視線検出部130は、視線検出カメラ151から取得した撮影データから、ユーザの両目の位置を検出し、検出した両目の間隔を測定する。
