Abstract
An OCT device includes an OCT optical system and a controller that also serves as an image processor. The controller acquires the OCT data of the fundus by processing the spectral interference signal output from the OCT optical system. In addition, the controller adjusts the position of the high accuracy region, which is the depth region where relatively high accuracy OCT data is obtained, by controlling the OCT optical system in accordance with the curvature level of the fundus image in the photographing range of the OCT data. This makes it possible to acquire good OCT data regardless of the curvature level of the fundus.
