Abstract: An image acquisition unit (2020) acquires a captured image containing an inspection target instrument. An inspection information acquisition unit (2040) acquires inspection information regarding the instrument contained in the captured image. The inspection information is information indicating an inspection item of the instrument. A first display control unit (2060) displays an indication representing an inspection spot corresponding to the inspection item indicated by the inspection information on the display device (10). For example, the first display control unit (2060) displays the indication representing the inspection spot so that the indication is superimposed on the inspection spot on a display device (10). For example, the first display control unit (2060) displays the indication in the inspection spot on the display device (10) or near the instrument.
