Abstract:
1. A fundus camera for photographing a fundus of an eye to be examined, the fundus camera comprising: a photographing optical system having a photographing optical axis, a focusing lens movable in a direction of the photographing optical axis, and an image-pickup element; alignment-state detection means for detecting a state of alignment of the photographing optical system with the eye; focusing-state detection means for detecting a state of focusing of the photographing optical system on the fundus; a fixation target Presenting unit which presents a fixation target for guiding a visual line to the eye, in which a presenting position of the fixation target is changeable between a reference position which is a position for photographing a central portion of the fundus and a peripheral position which is a position for photographing a peripheral portion of the fundus; a photographing starting switch; photographing-mode switching means for switching between a manual photographing mode in which photographing is performed based on an operation signal from the photographing starting switch, and an automatic photographing mode in which photographing is automatically performed based on results detected by the alignment-state detection means and the focusing-state detection means; fixation target presentation control means for controlling the fixation target presenting unit so that the Presenting position of the fixation target is brought to the reference position at a time of switching from the manual photographing mode to the automatic photographing mode, even though the presenting position of the fixation target is set to the peripheral position; and presenting-position changing means for inputting a change signal for changing the presenting position of the fixation target, wherein the photographing-mode switching means switches from the automatic photographing mode to the manual photographing mode based on a change signal for changing the presenting position of the fixation target from the reference position to the peripheral position.
