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