Abstract
An ophthalmic photographing apparatus includes: an interference optical system including a splitter that splits light, emitted from a measurement light source, into measurement light and reference light, and synthesizing the measurement light reflected on an eye with the reference light to guide the synthesized light to a detector; a driving part that moves an optical member arranged in the optical path to adjust an optical-path difference between the measurement light and the reference light; an image obtaining part that obtains a tomographic image of a fundus or an anterior segment based on a light receiving signal output from the detector; and a driving control unit that controls driving of the driving part to locate the optical member in a predetermined position corresponding to either a photographing mode for photographing the tomographic image of the fundus or a photographing mode for photographing the tomographic image of the anterior segment.
