Abstract:
A fundus camera capable of favorably photographing a fundus of an examinee's eye comprises a fundus photographing optical system comprising a visible light source which emits illumination light onto the fundus, a focusing lens movable in an optical axis direction thereof, and a fundus image pickup element, an optical system comprising a first photodetector, for detecting a focus state of the photographing optical system with respect to the fundus, a blink sensor which comprises a second photodetector and detects a blink of the eye based on a photo-receiving signal from the second photodetector, and a control unit arranged to suspend photographing upon input of a predetermined signal until the blink is detected by the sensor, and control the light source to emit the light when a predetermined period of time has passed since the blink is detected by the sensor in order to execute the photographing.
