PROBLEM TO BE SOLVED: To solve the problem that a reception state becomes worse when a posture is changed even if the good reception state of positioning radio waves is obtained in a certain posture since there is a dead angle in which a GPS antenna of a conventional camera cannot receive the positioning radio waves from right above over an angular range. SOLUTION: A controller 23 causes a switching circuit 21 to select outputs from the antennas 13, 14, 15 directed to the nearest orientation to an orientation of an airy region easy to receive the positioning radio waves based on a sensing result of a postural sensor 24. Even if the posture of the camera 1 is a horizontal posture or a vertical posture when the camera 1 captures an image, the positioning radio waves can be satisfactorily received. The dead angle in which the conventional camera cannot receive the positioning radio waves from right above over an angular range is eliminated. COPYRIGHT: (C)2009,JPO&INPIT
