A picture photographed by a camera portion is sent to a video capturing portion of a computer. The picture is displayed in an operation area of a monitor. A panorama picture of which pictures in part or all moving range of a pan tiler are combined is displayed in a panorama operation area. A pan tilter portion sends positional information of pan and tilt to the computer through a mode controller. With a mouse, the operation area and the panorama operation area are operated so as to select an object. The computer obtains data for driving the pan tilter. Thus, the selected object is displayed at the center of the operation area.
