System and method for whiteboard collaboration
First Claim
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.

Abstract
Disclosed is a method and tool for collaborating in a video conference using a non-electronically enhance whiteboard and without the use of electronically enhanced writing and/or pointing tools. An embodiment may set up a front camera to capture an overall video stream that is split into at least two video feeds, a whiteboard feed and presenter feeds. The front camera may be set up to have a depth of field and focus to capture the whiteboard and presenter as well as specific video capture settings for each feed to optimize the whiteboard or the presenter. An embodiment may capture the two feeds according to the appropriate settings and deliver the two feeds to other video conference member devices. Embodiments may add additional cameras to permit additional optimization such as eliminating whiteboard occluded areas and/or automatically selecting a presenter from a plurality of people who are in the video capture frame.
