Then, an input/output unit 150 of the information display apparatus displays the captured image, and displays distribution of the collation images with the scale of the subject, and performs guide display corresponding to the scale of the subject in the captured image on display of the distribution. The guide display moves on the display of the distribution corresponding to change in an angle of view.
