1. 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.

15. A method of obtaining information provided on a writing surface and a second area spaced apart from the writing surface in a room, the method including:
-
locating an image capturing system at a second location in the room remote from the writing surface and the second area;
sensing visual images from each of the writing surface and the second area with the image capturing system, wherein sensing comprises sensing successive linear array portions of the visual images;
identifying information provided on the writing surface and the second area with the image capturing system, wherein identifying information includes identifying information as a function of reference visual images of the writing surface and the second area;
reimaging at least the at least one area of the writing surface and the second area to obtain at least one second visual image; and
combining first-mentioned at lease one visual image with the second at least one visual image, wherein sensing includes sensing a plurality of visual images of each of the writing surface and the second area, wherein identifying includes identifying information as a function of the plurality of visual images from each of the writing surface and the second area, wherein identifying information includes detecting at lease one area of the writing surface and the second area requiring reimaging. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22)
