Camera control system and associated pan/tilt head
First Claim
1. A method for controlling the motion of a camera using a computer and a control screen, comprising:
- (1) displaying an image from the camera on the control screen;
(2) in response to the selection of an initial point on the control screen by a user using a pointing device, designating the initial point as a center of motion control; and
(3) in response to the user moving the pointing device from the initial point to a second point on the control screen;
(a) displaying on the control screen a dynamic vector line between the initial point and the second point; and
(b) moving the camera from an initial position to a second position, wherein the distance from the initial point to the second point on the control screen determines the speed at which the camera moves from the initial position to the second position and wherein the direction from the initial point to the second point on the control screen determines the direction in which the camera moves; and
(c) slowing the camera movement as the pointing device is moved from the second point back to the initial point.

Abstract
An apparatus for controlling one or more cameras is provided. The apparatus includes: a mounting sled, a tilt drive motor, a tilt drive train, a pan drive motor, and a pan drive train. The mounting sled includes a camera platform between two sled runners. A lower surface of each sled runner is formed by a circular arc. The tilt drive train includes a tilt drive shaft having an axis perpendicular to the camera platform. The pan drive train includes a pan drive shaft extending along the axis of the tilt drive shaft such that it receives the tilt drive shaft and turns independently and concentrically about the tilt drive shaft. The camera platform receives a camera such that the center of gravity of the camera is aligned with the diameter of the circular arc of the sled runners and the vertical axis of the tilt and pan drive shafts.

5. A method for preparing a composed shot from a camera using a computer and a control screen, comprising:
-
displaying a first image from the camera on the control screen; automatically drawing on the control screen a composition box in response to the selection of an initial point on the control screen by a user, wherein the composition box indicates an aspect ratio of the camera and the initial point indicates an upper left corner of the composed shot; automatically adjusting the size of the composition box based on the selection of a second point on the control screen by the user to maintain the aspect ratio; optionally adjusting the size or location of the composition box to define the composed shot based on input by the user; automatically moving the camera and/or adjusting the zoom of the camera, as needed, to change the image displayed on the control screen from the first image to the composed shot.
