PROBLEM TO BE SOLVED: To improve the convenience of a device for a user in the case of performing tomographic imaging again, and to reduce temporal load on a subject in the case of performing tomographic imaging.SOLUTION: A tomographic image of a target object for inspection is acquired in response to a signal input by signal input means, which inputs a signal for acquiring an image of the target object. The acquired tomographic image and a display mode for selecting re-acquisition of a tomographic image of the target object are displayed by display means. After the tomographic image is displayed by the display means, a surface image of the target object is acquired in response to a signal input by the signal input means.SELECTED DRAWING: Figure 3
