Abstract
A method for avoiding invalid camera positioning in a video conference establishes a boundary within the view of a camera, such that when a request is made to direct the camera to a point outside of the boundary, the camera positioning module transforms the request to one requesting the camera to be directed to a point just within the boundary. In one embodiment, the boundary includes a maximum extent and a minimum extent, corresponding respectively to the maximum and the minimum expected heights of a speaker.
