The projection unit projects an index including at least one of a predetermined continuous pattern and a predetermined discrete pattern on the anterior eye part of the eye to be examined. The two or more imaging units image the anterior eye part onto which the index is projected from different directions. The cornea shape information acquisition unit acquires cornea shape information on the eye to be examined based on at least one of two or more first captured images acquired by the two or more imaging units. The position determination unit determines a movement target position of the data acquisition optical system based on two or more second captured images acquired by the two or more imaging units and the cornea shape information.SELECTED DRAWING: Figure 1
