Patent ID: 8646912

Claim:
A fundus photographing apparatus arranged to perform fluorescent photographing by projecting flash light for fluorescent excitation onto an examinee's eye, the apparatus comprising: a photographing optical system comprising a focusing lens movable in an optical axis direction and arranged to photograph a fundus of the eye illuminated by photographing illumination light; an alignment detection optical system arranged to photo-receive by a first image pickup element an alignment target projected onto the eye by an alignment target projection optical system and detect an alignment state of the photographing optical system with respect to the eye based on a photo-receiving result by the first image pickup element; a focus detection optical system arranged to photo-receive by a second image pickup element a focus target projected onto the fundus by a focus target projection optical system and detect a focus state of the fundus adjusted by movement of the focusing lens based on a photo-receiving result by the second image pickup element; a light emission control unit arranged to control a light source to perform successive light emission of the flash light for fluorescent excitation at predetermined time intervals in a predetermined period in order to perform fluorescent photographing; and a movement control unit arranged to perform movement control of the photographing optical system with respect to the eye in an automatic manner based on a detection result obtained by the alignment detection optical system during the predetermined period of the successive light emission by the light emission control unit.
