Patent ID: 8456503

Claim:
A method comprising: obtaining a sequence of pictures from a camera associated with a video conferencing endpoint; determining a presence of a target point coinciding with an optical source within a field of view of said camera, wherein the optical source emits pulses of electromagnetic radiation at a rate that causes the camera to capture some frames with a pulse of electromagnetic radiation from the optical source and some frames without the pulse of electromagnetic radiation from the optical source; determining a location of said target point within one or more of said pictures by comparing a first frame from the camera that includes the pulse of electromagnetic radiation from the optical source and a second frame from the camera that does not include the pulse of electromagnetic radiation from the optical source; moving said camera so that a center of one or more subsequent pictures obtained by said camera coincides with said target point; and zooming said camera until receipt of an instruction to stop zooming is received, or until maximal zoom is achieved.
