An optical tomographic image photographing apparatus includes: an interference optical system for combining reflected light with reference light on an object to guide the combined light to a detector a driving part for moving an optical member in an optical-axis direction in order to adjust an optical path difference between measurement light and the reference light an image obtaining part for obtaining a tomographic image of the object based on a light receiving signal output from the detector and a control unit configured to detect positional deviation with respect to a depth direction in the tomographic image and to correct a display position of the tomographic image such that the tomographic image is displayed in a predetermined position within a display region on a monitor.
