Automatic Camera Framing for Videoconferencing
First Claim
1. An automated videoconferencing method, comprising:
- segmenting a wide view of an environment into first tight views;
directing a first camera on an endpoint to frame each of the first tight views;
determining relevance of each of the first tight views by analyzing the first video captured with the first camera in each of the first tight views;
determining a framed view defined by the first tight views determined relevant;
directing a second camera of the endpoint to frame the framed view; and
outputting second video for the videoconference, the second video captured with the second camera in the framed view.

Abstract
A videoconferencing apparatus automatically tracks speakers in a room and dynamically switches between a controlled, people-view camera and a fixed, room-view camera. When no one is speaking, the apparatus shows the room view to the far-end. When there is a dominant speaker in the room, the apparatus directs the people-view camera at the dominant speaker and switches from the room-view camera to the people-view camera. When there is a new speaker in the room, the apparatus switches to the room-view camera first, directs the people-view camera at the new speaker, and then switches to the people-view camera directed at the new speaker. When there are two near-end speakers engaged in a conversation, the apparatus tracks and zooms-in the people-view camera so that both speakers are in view.

18. A videoconferencing apparatus, comprising:
-
at least one camera being controllable to pan, tilt, and zoom; and a processing unit operatively coupled to the at least one camera, the control unit being operable to; segment a wide view of an environment captured by the at least one camera into a plurality of first tight views; direct the at least one camera to capture first video in each of the first tight views; analyze the first video in each of the first tight views for relevance; restrict the wide view to a framed view defined by the first tight views analyzed as relevant; and direct the at least one camera to capture second video in the framed view. - View Dependent Claims (19, 20, 21, 22)
