Optical tomographic image photographing apparatus and control method therefor |
摘要 |
An optical tomographic image photographing apparatus having a tracking function, capable of appropriately controlling a scan in acquiring a tomographic image. The optical tomographic image photographing apparatus according to the invention includes a fundus image photographing section which photographs fundus images of an eye to be inspected and a tomographic image photographing section which photographs tomographic images of the eye to be inspected. A control method of the optical tomographic image photographing apparatus includes the steps of: calculating coordinate values matching a plurality of previously-acquired characteristic areas in the fundus image; calculating a spatial variation between the plurality of coordinate values; and controlling the scan of a measuring light by the tomographic image photographing section for acquiring the tomographic images on the basis of a result of the calculation. |
