To realize a configuration enabling processing of displaying a flight path of a drone on a live-action image of the drone and the like. A data processing unit of a user terminal sets a real object included in a camera-captured image as a marker, generates marker reference coordinates with a configuration point of the set marker as an origin, and transmits position data on the marker reference coordinates to a mobile device such as a drone with the marker reference coordinates as coordinates shared with another device, for example, a mobile device such as a drone. For example, the data processing unit transforms the destination position of the drone or the position of the tracking target from the coordinate position on the user terminal camera coordinates to the coordinate position on the marker reference coordinates by applying the coordinate transformation matrix, and transmits the transformed coordinate position to the drone. In addition, the data processing unit receives the movement path from the drone as coordinate position data on the marker reference coordinates, transforms the coordinate position data into a coordinate position on the user terminal camera coordinates by applying the coordinate transformation matrix, and displays the path information on the display unit.
