A fundus photographing apparatus includes: a photographing unit including a fundus illumination optical system to illuminate a fundus of a patient's eye and a fundus photographing optical system having a light receiving element to obtain a fundus image of the illuminated eye; and an alignment unit to position the photographing unit with the eye based on a predetermined alignment reference position. The alignment unit includes: an extracting part to extract, by image processing, an image region formed by reflection light from a portion other than the fundus from the fundus image obtained by the fundus photographing optical system; a gravity center calculating part to determine, by arithmetic processing, a gravity center position of the extracted image region; and a control part to perform alignment control of the photographing unit with the eye based on the calculated gravity center position and the alignment reference position.

Fundus photographing apparatus

An ophthalmic apparatus comprising: a fundus observation optical system; a designating part for designating an area of the fundus other than a macular area from a fundus image displayed on a monitor to make alignment of the fundus area of the fundus image displayed on the monitor with the fixation target displayed on a LCD display; a judging part for detecting an approaching state of the fixation target projected on the fundus and the designated fundus area based on positional information of the fundus area designated by the designating part on the monitor after movement and positional information of the fixation target displayed on the LCD display, and judging based on a detection result, whether or not the designated fundus area and the fixation target projected on the fundus are coincident in a predetermined allowable range; and a display control part for changing the display state of the fixation target based on a judgment result of the judging part.
