ABSTRACT:
A method for automatically adjusting the pan and tilt of a camera, such as used in a videoconferencing system. A pointer and a picture of the camera's field of view are provided on a display device, such as a television set or a monitor. The pointer is moved on the display device in response to user commands from a user control device, such as a mouse or a joystick. When the user determines that the pointer is in the correct position the user uses the user control device to send a designation command. Then, in response to the designation command, the pan and/or tilt of the camera are adjusted to center the desired object in the picture. The method also provides: for ignoring the designation command if the amount of panning and/or tilting does not exceed a predetermined value; for zooming out prior to panning and/or tilting and then zooming in after panning and/or tilting if the amount of panning and/or tilting exceeds a predetermined value; and for adjusting the rates of panning and/or tilting so as to complete panning and tilting at approximately the same time.
