Zusammenfassung:PROBLEM TO BE SOLVED: To provide an ophthalmographic device capable of performing the ophthalmography in a proper exposure.SOLUTION: An ophthalmographic device comprises an illumination optical system, an imaging optical system, and an exposure control part. The illumination optical system illuminates the ocular fundus of an optometry with an illumination light. The imaging optical system includes an imaging element for detecting the fundus reflection light of the illumination light at the unit of a pixel unit while switching the exposure timing by a plurality of pixel lines sequentially with a predetermined time difference. The exposure control part changes the amount of exposure of the fundus reflection light by the imaging element, in response to the switching of the exposure timing by the plurality of pixel lines.
