A dual-wavelength fundus imaging apparatus comprises: a beam emitter (1) adapted to simultaneously emit first and second laser beams having a different wavelength from the first beam a filter disc (20) having a first filter (24), a second filter (25), and an opening (26) an imaging optical system having the filter disc and a photo-receiving element (14) a rotator (21) for rotating the filter disc a sensor (23) for detecting a rotation angle of the filter disc control means (30) for controlling the beam emitter to simultaneously emit the first and second beams at respective predetermined powers and image processing means (33) for obtaining a first and second fluorescent fundus image based on received light signals from the photo-receiving element. The control means is adapted to control at least one of the beam emitter, the irradiation optical system, and the imaging optical system based on a detection signal of the sensor to reduce respective light amounts of the first and second beams to be received by the photo-receiving element while the opening is disposed in the optical path of the imaging optical system.
