PROBLEM TO BE SOLVED: To enlarge a dynamic range of an imaging range without depending on a scanning angle of scanning means even when a wide-imaging-range imaging part imaging a wide region of a fundus with low resolution and an imaging part narrow-imaging-range imaging part imaging a narrow region of the fundus with high resolution comprise the common scanning means.SOLUTION: An imaging device irradiates an examined eye with light scanned by scanning means in a state that a ratio in a narrow imaging range is smaller than a ratio in a wide imaging range with respect to a ratio between an irradiation angle at which an anterior ocular segment of the examined eye is irradiated with the light scanned by the scanning means and a scanning angle of the scanning means.COPYRIGHT: (C)2014,JPO&INPIT【課題】 眼底の広い部位を低解像度に撮像する広撮像範囲撮像部と眼底の狭い部位を高解像度に撮像する撮像部狭撮像範囲撮像部とを共通の走査手段で構成した場合でも、走査手段の走査角度に依存することなく、撮像範囲のダイナミックレンジを広げること。【解決手段】走査手段により走査された光を被検眼の前眼部に照射する照射角度と走査手段の走査角度との比率に関して、広撮像範囲の比率よりも狭撮像範囲の比率が小さい状態で、走査手段により走査された光を被検眼に照射する。【選択図】 図1
