Claim 0:
1. A computer-implemented method for extracting content from a physical writing surface, the method comprising the steps of:
(a) receiving a reference frame including image data relating to at least a portion of the physical writing surface, the image data including a set of data points;
(b) determining an extraction region, the extraction region including a subset of the set of data points from which content is to be extracted;
(c) extracting content from the extraction region and writing the content to a display frame;
(d) receiving a subsequent frame including subsequent image data relating to at least a portion of the physical writing surface, the subsequent image data including a subsequent set of data points;
(e) determining a subsequent extraction region, the subsequent extraction region including a subset of the subsequent set of data points from which content is to be extracted;
(f) extracting subsequent content from the subsequent extraction region and writing the subsequent content to the display frame; and
wherein steps (e) to (f) are repeated for a period of time for a series of subsequent frames, and wherein the method further includes the step of removing the subsequent content associated with an earlier subsequent frame in the series of subsequent frames from the display frame.
