PROBLEM TO BE SOLVED: To prevent a main body from being photographed by picking up an image at an angle of view suitable for the image pickup direction of an image pickup part even when the image pickup direction is switched and then the image is picked up. SOLUTION: An antenna state detection part 102 decides whether an antenna 101 is extended or contracted. A variable zoom mechanism 112 varies the angle of view of a camera 111 according to the indication from a control part 100. An image pickup direction detection part 113 detects the image pickup direction of the camera 111. The control part 100 sets the initial angle of view of the camera 11 and the variation range of the angle of view according to the image pickup direction of the camera 111 detected by the image pickup direction detection part 113, the state of the antenna 101 detected by the antenna state detection part 102, and a view-angle data table stored in a memory 107.
