摘要:
This object aims to provide an ophthalmic device in which an alignment adjusting manipulation or a focusing manipulation can be easily carried out at a manual operation and an alignment adjusting operation or a focusing operation can be surely achieved at an automatic operation regardless of a display condition of a target of an optical image used for carrying out the alignment adjusting manipulation and the focusing manipulation. An ophthalmic device is provided with a photographing optical system (20) that photographs an eye fundus (Ef) an illumination optical system (30) that illuminates the eye fundus (Ef) a split target projection optical system (60) that projects a split target (SL) for focusing the photographing optical system (20) on the eye fundus (Ef), an alignment target projection optical system (40) that projects an alignment target(AL) for aligning the photographing optical system (20) with an examining eye (E) an observation optical system (30) that displays optical images of the eye fundus (Ef), the split target (SL) and the alignment target (AL) on a monitor (31) and a quasi-target display processing unit (316) that takes an observation video signal output by the observation optical system in, detects at least one of positions of the split target (SL) and the alignment target (AL) in the observation video signal, and displays a quasi-target on the monitor (31) in accordance with the detected position.
