Ophthalmologic imaging apparatus and ophthalmologic imaging method

摘要

An ophthalmologic imaging apparatus includes an observation light source configured to generate infrared light for illuminating a subject's eye via an illumination optical system, an imaging unit configured to receive light returned from the subject's eye via an imaging optical system, and an electronic shutter control unit configured to refresh charge generated caused by light received by the imaging unit in response to turning off of the observation light source.

主权项

1. An ophthalmologic imaging apparatus comprising:
a first light source configured to generate infrared light for illuminating a subject's eye via an illumination optical system; a second light source configured to generate visible light for illuminating the subject's eye via the illumination optical system; an imaging unit including a receiving surface configured to receive light returned from the subject's eye illuminated with the infrared light via an imaging optical system, the imaging unit being used both as an imaging device configured to capture a moving image of the subject's eye illuminated with the infrared light and as an imaging device configured to capture a still image of the subject's eye illuminated with the visible light; an electronic shutter control unit configured to refresh, by electronic shutter processing, charge caused by light received by the imaging unit after turning off the first light source;
an irradiation control unit configured to control the second light source to generate the visible light after the charge is refreshed; and an obtaining unit configured to obtain a still image of the subject's eye based on charge caused by light returned from the subject's eye illuminated with the visible light and received by the receiving surface via the imaging optical system.
