A fundus camera includes an optical path splitting unit arranged between a focusing unit and an imaging unit. The optical path splitting unit has characteristics adapted to reflect light of a visible light region and to transmit near-infrared light. The optical path splitting unit retreats from an optical path when a still fundus image is photographed. A quick-return mirror having such characteristics is used as the optical path splitting unit. When near-infrared illumination light having a wavelength of about 850 nm is used, such light can be incident upon the imaging unit without loss of the amount of light. In addition, visible light output from an internal fixation target is projected onto a subjects eye. Further, a cornea diaphragm and a crystalline lens diaphragm are used for observing a fundus with invisible light. Each of the cornea diaphragm and the crystalline lens diaphragm can be changed to another one having a different diameter.
