Patent ID: 6904182

Claim:
An image capturing system comprising: a visual sensor adapted to provide image data corresponding to sensed visual images of a writing surface and a second area spaced apart from the writing surface, wherein the sensed visual images each comprise successive linear array portions; an image processor coupled to the visual sensor to receive the image data from the visual sensor, the image processor adapted to identify information provided on the writing surface apart from the writing surface and further adapted to identify information provided on the second area apart from the second area; a storage device for storing reference visual images, wherein the image processor is coupled to the storage device to access the reference visual images corresponding to each of the writing surface and the second area to identify information provided on the writing surface and the second area, wherein the image processor is adapted to identify an area requiring reimaging, and wherein the image processor controls the visual sensor to obtain at least one second visual image corresponding to the at least one portion of the writing surface or the second area, if reimaging is required, and wherein the processor is adapted to combine the first-mentioned visual images with the at least one second visual image.
