Adaptive Switching of Views for a Video Conference that Involves a Presentation Apparatus
First Claim
1. A method comprising:
- receiving a first signal that includes a video signal derived from a video camera that is viewing a room during a conference session in which a person is presenting information on a presentation apparatus, wherein the video signal provides a perspective view of the presentation apparatus in the room;
determining whether the person is outside an operable region with respect to the presentation apparatus; and
switching between the first signal and a second signal representing content being displayed on the presentation apparatus during the conference session for output and transmission to other conference endpoints of the conference session, such that when it is determined that the person is outside the operable region with respect to the presentation apparatus, the second signal is selected for output, and when it is determined that the person is inside the operable region with respect to the presentation apparatus, the first signal is selected for output.

Abstract
Techniques are provided for dynamically adapting the view from a conference endpoint that includes a presentation apparatus, such as a whiteboard. A first signal is received that includes a video signal derived from a video camera that is viewing a room during a conference session in which a person is presenting information on a presentation apparatus. During the video conference, switching is performed between the first signal and a second signal representing content being displayed on the presentation apparatus during the conference session for output and transmission to other conference endpoints of the conference session. The determination as to whether to supply the first signal (for a normal view of the conference room) or the second signal may be based on a position determination of the presenter or may be instead be based on an external view selection command received from another conference endpoint participating in the conference session.

12. An apparatus comprising:
-
a video camera configured to generate a video signal for a view a room during a conference session in which a person is presenting information on a presentation apparatus, wherein the video signal provides a perspective view of the presentation apparatus in the room; and a processor configured to; receive a first signal that includes the video signal; determine whether the person is outside an operable region with respect to the presentation apparatus; and switch between the first signal and a second signal representing content being displayed on the presentation apparatus during the conference session for output and transmission to other conference endpoints of the conference session, such that when the processor determines that the person is outside the operable region with respect to the presentation apparatus, the processor selects the second signal for output the second signal, and when the processor determines that the person is inside the operable region with respect to the presentation apparatus, the processor selects the first signal for output. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)

20. One or more computer readable storage media encoded with software comprising computer executable instructions and when the software is executed operable to:
-
receive a first signal that includes a video signal derived from a video camera that is viewing a room during a conference session in which a person is presenting information on a presentation apparatus, wherein the video signal provides a perspective view of the presentation apparatus in the room; determine whether the person is outside an operable region with respect to the presentation apparatus; and switch between the first signal and a second signal representing content being displayed on the presentation apparatus during the conference session for output and transmission to other conference endpoints of the conference session, such that when it is determined that the person is outside the operable region with respect to the presentation apparatus, the instructions operable to switch comprise instructions operable to select the second signal for output, and when it is determined that the person is inside the operable region with respect to the presentation apparatus, the instructions operable to switch comprise instructions operable to select the first signal for output. - View Dependent Claims (21, 22, 23)
