In a tomography apparatus that captures tomograms of a fundus through optical coherence tomography, when a measurement area in which tomograms are to be captured is set on the fundus, tomograms are acquired with use of the optical coherence tomography at a plurality of predetermined positions in the set measurement area, the number of predetermined positions being smaller than in the case of imaging for diagnosis. The acquired tomograms are then displayed inline on the screen of a display apparatus in real-time.
