ABSTRACT:
Provided is an ophthalmologic image taking apparatus with which an image of the eye to be examined can be taken with an appropriate light intensity and at an appropriate gain. In the case where an observation of an eye to be examined is conducted when it is detected that an image taking switch is turned on, an image taking light source emits light after a lapse of a predetermined time. The predetermined time is a time required to completely switch a gain from a gain obtained by AGC to a fixed gain and a time which is not influenced by blinking of the eye to be examined.
