Patent ID: 7258442

Claim:
An eye fundus photographing system, comprising: an illumination optical system that includes a light source for emitting illumination light and an exciter filter for transmitting a specific wavelength region of the illumination light emitted from the light source and that emits the illumination light passing through the exciter filter to a fundus of an eye to be examined; a photographing optical system including right and left objective lenses for taking right and left photographing light beams based on infrared fluorescence radiated from an infrared fluorescent dye material excited by the illumination light emitted to the fundus and a barrier filter for transmitting a predetermined infrared wavelength region of each of the right and left photographing light beams; right and left photographing means for obtaining photographed images of respective frames based on the right and left photographing light beams passing through the barrier filter; synchronization means for synchronizing the respective frames between the right and left photographing means; and three-dimensional image displaying means for displaying a three-dimensional moving picture image based on the photographed images of the synchronized respective frames which are obtained by the right and left photographing means.
