Abstract
Abstract A current image-sensing area of a camera is displayed as a first frame, and a potential image-sensing area obtainable by panning/tilting the camera at an image-sensing magnification is displayed as a second frame. To control panning/tilting of the camera, a display position of the second frame is changed, and in accordance with the changed display position, control data is transferred to the camera.
