Abstract: A swing unit (411) performs swing control of causing a camera which photographs a stationary object to change a photographing range. A position calculation unit (413) calculates a last-time position representing a portion showing the stationary object in a last-time image obtained by the camera before the swing control, and a this-time position representing a portion showing the stationary object in a this-time image object obtained by the camera after the swing control. A verification unit (415) determines whether the this-time image is a false image based on a quantity of change in the photographing range resulting from the swing control and a quantity of change in the this-time position from the last-time position.
