PURPOSE:To always obtain a focused state and an image of an object to be photographed of a constant size without manual operation by utilizing a tilt angle or a pan angle of a universal head device, and controlling automatically a focusing control means and a variable power control means of a camera. CONSTITUTION:In accordance with a tilt angle theta, a tilt angle signal S1 is outputted. A tilt angle signal generator 6 is connected to a focusing control means 9 and a variable power control means 10 of a camera 3 through a series connecting body of a tilt angle encoder 7 and an operating means 8. The operating means 8 operates a distance D by a signal S2, and an operated signal S3 and S4 are outputted. The focusing control means 9 controls a focused state of the camera 3 by the signal S3, and the variable power control means 10 executes a variable power of a zoom lens system by the signal S4. The signal S3 and the signal S4 are inputted to the focusing control means 9 and the variable power control means 10, respectively, they are always controlled to a focused state, and size of an image of an object to be photographed can be made constant. |
