Abstract

Disclosed is a system and method for automatic adjustment to a camera field of view based on parameters negotiated during a video conference initiation.

Claims

1. A method for automatically controlling a field of view of a video conference camera, said method comprising:

initiating a video conference with a first endpoint and a second endpoint;

negotiating a session between the first endpoint and the second endpoint; and

automatically adjusting a camera field of view in accordance with the negotiation of said session, by modifying an angular extent of a scene imaged by said camera and displayed at one of said endpoints, to accommodate a preferred field of view setting;

wherein said modifying an angular extent of a scene imaged by said camera and displayed at one of said first endpoint and said second endpoint comprises changing one of a pan/tilt/zoom setting of said camera and a cropping and scaling of said image captured by an image sensor of said camera.

2. The method of claim 1, wherein the process of negotiating a session comprises providing at least one additional parameter to a protocol.

3. The method of claim 2, wherein the protocol is Session Description Protocol.

4. The method of claim 2, wherein the at least one additional parameter comprises one of screen size parameter and screen resolution parameter.

5. The method of claim 1, wherein the process of negotiating a session comprises providing a plurality of additional parameters to a protocol.

6. The method of claim 5, wherein the protocol is Session Description Protocol.

7. The method of claim 5, wherein the plurality of additional parameters comprises a screen size parameter and a screen resolution parameter.

8. The method of claim 1, wherein the process of automatically adjusting a camera field of view comprises looking up information received in the negotiating process to determine a preferred field of view.

9. The method of claim 8, wherein the information is looked up in a table.

10. A system for automatically controlling a field of view of a video conference camera, said system comprising:

a first video conference endpoint;

a second video conference endpoint; and

negotiation of video conference parameters;

wherein the video conference parameters, comprising a camera field of view for at least one of the first endpoint and the second endpoint, are negotiated between the first and second endpoints using a protocol and at least one of a camera field of view at said first and second endpoint is automatically adjusted in accordance with the parameters negotiated and wherein said adjustment comprises a modification of an angular extent of a scene imaged by a camera of at least one of said first and second endpoints to accommodate a preferred field of view setting.

11. The system of claim 10, wherein said conference parameters comprise at least one of a screen size parameter and a screen resolution parameter.

12. The system of claim 11, wherein said automatic adjustment is made in reference to a display size table.

13. The system of claim 10, wherein said conference parameters comprise both a screen size parameter and a screen resolution parameter.

14. The system of claim 13, wherein said automatic adjustment is made in reference to a display size table.
