A monocular image of a fundus of an eye under examination is captured via a photographic stop for monocular photography, and two stereographically viewed images are captured with a parallax via two photographic stops for stereographic photography that are decentered from a photographic optical axis. Defocused images are captured in the stereographic photography due to the deviation of the photographic stops from the optical axis. A corrective lens is inserted into the photographic optical path in order to correct the defocus in the stereographic photography. This makes it possible to readily correct defocus generated by deviation of the photographic stops from the photographic optical axis even when switching between monocular and stereographic photography modes.
