Patent ID: 8639032

Claim:
A computer-implemented process comprising the steps of setting a digital imaging device to capture a preselected field of view, the field of view having a whiteboard subject to periodic change by a foreground speaker: capturing a sequence of frames with the digital imaging device of the whiteboard and the foreground speaker writing on the whiteboard; capturing audio linked with the captured sequence of frames; establishing a first timecode value associated with the initiation of writing by the foreground speaker in a first region of the whiteboard, first region identified by applying an edge detection algorithm; establishing a second timecode value associated with the initiation of writing by the foreground speaker in a second region of the whiteboard, the second region identified by applying an edge detection algorithm; automatically broadcasting the captured audio and displaying the first region as magnified images from the sequence of frames from the first timecode value until the second timecode value; and automatically broadcasting the captured audio and displaying the second region as magnified images from the sequence of frames from the second timecode value.
