Abstract:
1. An ophthalmological photographing apparatus for photographing a fundus image of an eye to be examined multiple times, comprising: image sensing means for photographing the fundus image and converting the fundus image into a digital signal; a photographing light source for illuminating a fundus of the eye to be examined; an image sensing optical system for illuminating the fundus image of eye to be examined at the time of photographing fundus image, by light from the photographing light source; setting means for setting the light intensity of light from the photographing light source, at a first time of photographing the fundus image; and control means for controlling the photographing light source so that the light intensity at a second time of photographing is larger than that at the first time of photographing, which is set by the setting means, wherein the control means determine the light intensity of the illumination light from the photographing light source at the second time of photographing, on the basis of a calculation result executed using the light intensity of the illumination light at the time of photographing and a value calculated on the basis of a diameter of pupil of the eye to be examined.
