PROBLEM TO BE SOLVED: To acquire a desired tomographic image of a subject at a high speed, improve operability of a user, and easily acquire a tomographic position of an optical coherence tomographic image displayed on a screen of a display device.SOLUTION: The OCT control device 100 of an OCT device (Optical Coherence Tomography imaging device) 1 captures images by controlling a galvano mirror 33 synchronous with laser light, and controls generation of OCT images (Optical Coherence Tomography images) of a subject from data converted from a detection signal of a detector 23. The OCT control device includes: an en-face imaging means 151 for generating an en-face image in which information of the surface of the subject to which the laser light is applied, and information of the subject in the direction along the optical axis are combined, as a two-dimensional image of a scan surface in the direction perpendicular to the optical axis in the subject a tomographic position line generating means 154 for linearly drawing and superimposing the tomographic position of the OCT image on the en-face image and an optical coherence tomography imaging means 152 that accepts a command to select and move the line of the tomographic position and generates the OCT image based on the position of the line.
