Summary:To provide a simple and accurate imaging system for re-authentication when an iris authentication fails.SOLUTION: An imaging system 10 includes: a first control unit configured to control, in such a way as to fix a focal position in a predetermined position, iris imaging means for capturing an image focusing on an iris of a target person; an authentication unit configured to authenticate the target person, based on an iris image of the target person captured by the iris imaging means controlled by the first control unit; and a second control unit configured to control the iris imaging means in such a way as to scan a focal position in a predetermined range, in order to re-authenticate the target person when authentication of the target person fails.SELECTED DRAWING: Figure 1 【課題】虹彩認証失敗時の再認証を行うための簡便でかつ確実な撮像システムを提供する。【解決手段】本開示にかかる撮像システム１０は、対象者の虹彩に合焦した画像を撮像するための虹彩撮像手段に対し焦点位置を所定の位置に固定するよう制御する第１の制御部と、第１の制御部により制御された虹彩撮像手段が撮像した対象者の虹彩画像に基づいて、対象者を認証する認証部と、対象者の認証が失敗した場合、対象者を再認証するため、虹彩撮像手段に対し焦点位置を所定の範囲で走査するよう制御する第２の制御部と、を備えるものである。【選択図】図１
