Zusammenfassung: | A videoconferencing system includes different cameras with different fields-of-view (FOVs). Frames of images acquired by these cameras may be processed to determine states, such as number of users present, talking, and so forth. Based on these states, frames from one camera may be selected to send to a far site. If the two states indicate no change in camera source from a first time to a second time, the current frame from the first camera that is sent to the far site is followed by another frame from the same camera. If the two states indicate a change in camera source from the first time to the second time, the current frame from the first camera that is sent to the far site is followed by a frame from the different camera. Depending on the two states and the cameras used, different transition effects may be applied to improve presentation. |
