Abstract
In order to take a good tomographic image without a complicated position adjustment operation by an inspector, an ophthalmologic apparatus is provided which acquires a fundus tomographic image by optical coherence tomography utilizing interference by low coherence light. The ophthalmologic apparatus includes a tomographic image acquiring unit for acquiring a tomographic image of an eye to be inspected, a tilt calculation unit for calculating a tilt of the tomographic image, and a relative position changing unit for changing a relative position between the tomographic image acquiring unit and the eye to be inspected based on the tilt of the tomographic image. An evaluation index may be devised that indicates a problem with the tomographic image or an anterior ocular image and the relative position changing means may change the relative position according to this evaluation index. The evaluation index is linked to the tilt of the tomographic image.
