Abstract:
1. A fundus camera for photographing a fundus of an eye of an examinee, the fundus camera comprising: a photographing part in which a fundus photographing optical system is arranged; a moving unit which moves the photographing part; a fundus observation optical system having a first image-pickup element which picks up an image of the fundus; an anterior-segment observation optical system having a second image-pickup element which picks up an image of an anterior-segment of the eye; a display unit capable of displaying the fundus image picked up by the first image-pickup element and the anterior-segment image picked up by the second image-pickup element; a control part which obtains information on alignment of the photographing part with the eye and drives the moving unit based on the obtained alignment information so that an alignment state of the photographing part with the eye satisfies a first reference condition, stops the driving of the moving unit when the alignment state satisfies the first reference condition while allowing a display on the display unit to switch from the anterior-segment image to the fundus image and, drives the moving unit again based on the alignment information when the alignment state subsequently fails to satisfy a second reference condition which is set greater than the first reference condition; and a first input switch for inputting a signal for switching a display on the display unit from the fundus image to the anterior-segment image, wherein the control part prohibits the driving of the moving unit when the signal from the first input switch is input after the display is switched from the image of the anterior-segment to the fundus image, even if the alignment state fails to satisfy the second reference condition.
