Abstract:
An ophthalmologic photographing apparatus includes a light source having two or more types of light-emitting-diode (LED) light emitting elements configured to emit light of different wavelengths, an illumination optical system configured to illuminate a fundus of a subject's eye with light emitted by the light source, an imaging optical system configured to form a fundus image from light reflected from the fundus of the subject's eye illuminated by the illumination optical system, and a control unit configured to control the light source to emit light of different wavelengths, with which the fundus of the subject's eye is illuminated, between when the formed fundus image is observed and when the formed fundus image is captured as a still image.
