Patent Images
1. A computer readable medium including instructions readable by a computer which, when implemented, cause the computer to process images from a writing surface by performing the steps of:
- generating image data from a visual sensor adapted to provide the 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;
receiving the image data from the visual sensor using an image processor coupled to 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;
accessing stored reference visual images using the image processor coupled to a storage device, 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.

Abstract
An image capturing system is installable in a room separate from a writing surface and a second area. The image capturing system is adapted to take visual images of the writing surface and second area and identify information written thereon.

10. A computer readable medium including instructions readable by a computer which, when implemented, cause the computer to obtain information provided on a writing surface and a second area spaces apart from the writing surface in a room by performing the steps of:
-
receiving at least one sensed visual image from each of the writing surface and the second area with the image capturing system located at a location in the room remote from the writing surface and the second area, wherein the sensed visual images comprise successive linear array portions of the visual images; identifying information of the received sensed visual images from the writing surface and the second area, wherein identifying information includes identifying information as a function of reference visual images of the writing surface and the second area; receiving at least one reimaged visual image from each of the writing surface and the second area to obtain at least one second visual image; and combining the first-mentioned at least one visual image with the second at least one visual image, wherein identifying includes detecting at least one area of the writing surface and the second area requiring reimaging. - View Dependent Claims (11, 12, 13, 14, 15)
