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.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
