<P>PROBLEM TO BE SOLVED: To enable a smooth focus adjustment even when a diopter correction lens is inserted. <P>SOLUTION: A fundus camera includes: a fundus imaging optical system having a focusing lens disposed to move in a direction of an optical axis and a diopter correction lens disposed to be inserted into and detached from an optical path to correct the diopter of an eye with a strong refractive error for imaging an ocular fundus of a subject's eye; a target projection optical system for projecting a focus target to the ocular fundus of the subject's eye; a fundus observation optical system for observing an observation image of the ocular fundus of the subject's eye in addition to the focus target projected to the ocular fundus; an operational part for outputting an operational signal from an examiner to move the focusing lens in accordance with the operation by the examiner; and a driving controller which controls the driving of a driving part based on the operational signal output from the operational part and controls the driving part in a manner that the focusing lens moves at a moving speed higher than a speed in the evacuation of the diopter correction lens when the diopter correction lens is inserted. <P>COPYRIGHT: (C)2011,JPO&INPIT |
