摘要： An ophthalmic device is provided with a photographing optical system that photographs an eye fundus; an illumination optical system that illuminate the eye fundus; a split target projection optical system that projects a split target for focusing the photographing optical system on the eye fundus; an alignment target projection optical system that projects an alignment target (AL) for aligning the photographing optical system with an examining eye; an observation optical system that displays optical images of the eye fundus; and a pseudo-target display processing unit that takes an observation video signal output by the observation optical system in, detects at least one of positions of the split target and the alignment target in the observation video signal, and displays a pseudo-target on the monitor in accordance with the detected position.
