Abstract:
1. A method to collaborate in a video conference when a presenter uses a non-electronically enhanced writing surface, referred to herein as a whiteboard, and without using electronically enhanced writing and/or pointing tools, using a front camera that is operatively connected to a video processing-communication unit and is placed in front of said whiteboard in order to capture video of said whiteboard and said presenter using said whiteboard, said video conference collaboration method comprising: setting by said video processing-communication unit a depth of field and a focus for said front camera such that said front camera captures an image of said whiteboard and a predefined distance in front of said whiteboard as a presenter's area; setting by said video processing-communication unit said front camera to capture an overall front camera video stream as at least two video streams, a whiteboard video stream and a presenter video stream such that said whiteboard video stream and said presenter video stream are portions of said overall front camera video stream; setting by said video processing-communication unit whiteboard video capture settings of said whiteboard video stream on said front camera to optimize capture of said whiteboard; setting by said video processing-communication unit presenter video capture settings of said presenter video stream on said front camera to optimize capture of said presenter in said presenter's area in front of said whiteboard; capturing by said video processing-communication unit said whiteboard video stream and said presenter video stream using said front camera according to said depth of field, said focus, said whiteboard video capture settings, and said presenter video capture settings; and delivering by said video processing-communication unit a final conference whiteboard video stream based on said whiteboard video stream and a final conference presenter video stream based on said presenter video stream to member devices of said video conference.
