摘要：

PROBLEM TO BE SOLVED: To appropriately image the fundus image of an eye to be examined by reducing the size of a correction optical system for correcting the fixation disparity of a fundus.

SOLUTION: A fundus imaging apparatus including a fundus imaging optical system for receiving a luminous flux reflected against the fundus of the eye to be examined and imaging the fundus includes: a driving unit having a correction lens, which is arranged at a conjugate position with the pupil of the eye to be examined in the light path of the fundus imaging optical system so as to correct the disparity of an imaging position caused by micromotion in the fundus of the eye to be examined, and moving the correction lens in a direction to be orthogonally crossed with the light axis of the fundus imaging optical system position disparity detecting means having a light reception optical system for allowing a photodetector to receive the luminous flux reflected against the fundus of the eye to be examined, and detecting the position disparity of the fundus of the eye to be examined, based on the reception signal from the photodetector and driving control means for controlling the driving of the driving unit, based on the detection signal from the position disparity detecting means, thereby to correct the disparity of the imaging position caused by the motion of the fundus of the eye to be examined.
