Abstract

A method is provided in one example and includes receiving image data at a camera element that is provisioned at a first endpoint, which is configured to conduct a video session involving a second endpoint. The method also includes identifying an incoming request for the video session; signaling to the camera element to open a lens included within the camera element; detecting that the video session has been terminated; and signaling to the camera element to close the lens.

Claims

1. A method, comprising:

receiving image data at a camera element that is provisioned at a first endpoint, which is configured to conduct a video session involving a second endpoint;

identifying an incoming request for the video session;

upon identifying the incoming request for the video session, signaling to the camera element to open a lens included within the camera element;

detecting that the video session has been terminated; and

upon detecting that the video session has been terminated, signaling to the camera element to close the lens.

2. The method of claim 1, wherein the camera element is configured to operate as a light sensor to detect light energy within an environment in which the video session occurs.

3. The method of claim 1, wherein the light energy detected by the camera element is used to adjust a lens shutter provisioned within the camera element.

4. The method of claim 1, wherein the light energy detected by the camera element is used to adjust an exposure associated a selected portion of a field of view of the camera element.

5. The method of claim 1, wherein lighting parameters are designated before the video session begins to provide default shuttering and exposure settings.

6. The method of claim 1, wherein the lens has an optical zoom, and wherein the lens is configured to be tilted and panned using one or more application program interfaces (APIs).

7. The method of claim 1, wherein the camera element receives power over a universal serial bus (USB) link, and wherein the USB link carries at least a 1 ampere (A) current to the camera element.

8. Logic encoded in one or more non-transitory media that includes code for execution and when executed by a processor operable to perform operations comprising:

receiving image data at a camera element that is provisioned at a first endpoint, which is configured to conduct a video session involving a second endpoint;

identifying an incoming request for the video session;

upon identifying the incoming request for the video session, signaling to the camera element to open a lens included within the camera element;

detecting that the video session has been terminated; and

upon detecting that the video session has been terminated, signaling to the camera element to close the lens.

9. The logic of claim 8, wherein the camera element is configured to operate as a light sensor to detect light energy within an environment in which the video session occurs.

10. The logic of claim 8, wherein the light energy detected by the camera element is used to adjust a lens shutter provisioned within the camera element.

11. The logic of claim 8, wherein lighting parameters are designated before the video session begins to provide default shuttering and exposure settings.

12. The logic of claim 8, wherein the light energy detected by the camera element is used to adjust an exposure associated a selected portion of a field of view of the camera element.

13. The logic of claim 8, wherein the lens has an optical zoom, and wherein the lens is configured to be tilted and panned using one or more application program interfaces (APIs).

14. The logic of claim 8, wherein the camera element receives power over a universal serial bus (USB) link, and wherein the USB link carries at least a 1 ampere (A) current to the camera element.

15. An apparatus, comprising:

a camera element that includes a lens;

a memory element configured to store data; and

a processor operable to execute instructions associated with the data, wherein the processor and the memory element cooperate such that the apparatus is configured to;

receive image data at the camera element that is provisioned at a first endpoint, which is configured to conduct a video session involving a second endpoint;

identify an incoming request for the video session;

upon identifying the incoming request for the video session, signal to the camera element to open the lens included within the camera element;

detecting that the video session has been terminated; and

upon detecting that the video session has been terminated, signal to the camera element to close the lens.

16. The apparatus of claim 15, wherein the camera element is configured to operate as a light sensor to detect light energy within an environment in which the video session occurs.

17. The apparatus of claim 15, wherein the light energy detected by the camera element is used to adjust a lens shutter provisioned within the camera element.

18. The apparatus of claim 15, wherein the light energy detected by the camera element is used to adjust an exposure associated a selected portion of a field of view of the camera element.

19. The apparatus of claim 15, further comprising:

a display configured to render images associated with the video session, wherein the camera element receives power over a universal serial bus (USB) link, and wherein the USB link carries at least a 1 ampere (A) current to the camera element.

20. The apparatus of claim 15, further comprising:

a handset configured to control one or more application program interfaces (APIs) during a video session, wherein the lens has an optical zoom, and wherein the lens is configured to be tilted and panned using one or more of the APIs.
