In a case of right and left eye fundus image sensing in a mass health examination, the alignment of an anterior segment of an eye to be examined is performed first (S 101 ). When the alignment of the anterior segment of eye is completed, image sensing light intensity is set (S 102 ). The alignment of a fundus segment of the eye to be examined is performed (S 103 ). Furthermore, an image of the fundus of the eye to be examined is sensed by a sensing switch being pushed after the completion of focus adjustment (S 104 ). Next, an optical base unit is moved so that the image sensing of another eye can be performed (S 105 ). A left or right eye detection unit detects that an eye for image sensing is changed with the move of the optical base unit. When the eye for image sensing is changed, an image sensing light intensity setting unit sets image sensing light intensity by adding a predetermined amount, or changing the sets image sensing light intensity according to a diameter of a pupil (S 106 ). Then, alignment and the like are performed similarly to S 101 and S 103 (S 107 , S 108 ), and an image of another eye is sensed.
