An OCT apparatus that photographs with a plurality of measuring beams concurrently has a mechanism for adjusting the optical path length of a reference beam for each measuring beam. Accordingly, when tomographic images photographed in this manner are displayed side by side, because the depth of photographing varies from one tomographic image to another, it is difficult for an operator to comprehend the positional relation between the photographed images. In displaying tomographic images acquired with a plurality of measuring beams, the display position of each tomographic image is adjusted based on the changed optical path length of a reference beam of the measuring beam used for the image. The tomographic images are thus aligned in height and are presented in a manner that is easy for the operator to comprehend the positional relation between the photographed images.
