Abstract
An ophthalmologic apparatus includes a diaphragm, a photo taking system, having a mirror system with a deflection mirror, for taking an eye fundus through the mirror which is disposed in a position nearer to an eye to be examined than to the diaphragm on an optical path, and a controller. The controller controls the photo taking optical system so as to perform photo taking plural times by changing directions of the mirrors, so that a plurality of images for the eye fundus are obtained from a plurality of directions.
