Automatic position control method for television camera

Abstract

Abstract PURPOSE: To position automatically a camera at an assigned position by storing data on the position for a supervision in a vertical direction and rotational direction and then by moving the camera according to a difference between this stored data signal and preset position signal of the camera. CONSTITUTION: Position signal generation part 1 sends a positioning or fault signal to vertical position memory part 2 for a TV camera and rotational position memory part 3 to select set values, equivalent to position signals in memory parts 2 and 3, at to one point each in the vertical direction and rotational direction, and the set values are inputted to pulse controllers 4 and 5. On receiving those set values, TV- camera vertical position detection part 6 makes a comparison with the measured value of the present position signal and then supply a rotation or reversing signal, corresponding to the difference, to TV-camera vertical driving motor 8 to exercise vertical position control, thereby moving the camera to a desired position. In the rotational direction, the camera is similarly operated by TV rotational direction detection part 7 and rotational-direction driving motor 9 to move the camera. Those operations are carried out simultaneously and the camera in a stationary state send a video signal to video signal amplifier 11. COPYRIGHT: (C)1980,JPO&Japio
