In an imaging apparatus in which a plurality of sample images are stored, image data acquired by an imaging unit and a sample image used during imaging are displayed simultaneously on a monitor. Thus, a user is allowed to know a directory where image data is to be saved while imaging an object. Furthermore, operation of the imaging unit can be set based on data associated with the sample image. Accordingly, even a user who is not accustomed to operating the imaging apparatus is allowed to image an object with a setting suitable for the status of the object.
