1. An image capturing system comprising:
- a visual sensor providing image data corresponding to sensed images, the visual sensor selectively directed toward a first writing surface to sense successive linear array portions of a first image and toward a second area spaced apart from the first writing surface to sense successive linear array portions of a second image, wherein the first and second images are not portions of a single image; and
an image processor coupled to the visual sensor to receive the image data from the visual sensor, the image processor adapted to process the image data as a function of processing values, wherein the processing values are a function of direction of the visual sensor toward the first writing surface and the second area.

7. 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, and wherein the sensed visual images are not portions of a single image;
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; and
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. - View Dependent Claims (8, 9, 10)

11. An image capturing system comprising:
-
a visual sensor providing image data corresponding to sensed images from each of a writing surface and a second area spaced apart from the writing surface, the visual sensor comprising a set of adjacent sensing elements being exposed collectively to successive linear array portions of the images, wherein images on the writing surface and second area are not portions of a single image;
a storage device for storing sensing element control values; and
a controller coupled to the storage device and the visual sensor, the controller controlling a time duration of exposure of the sensing elements to each linear array portion of images as a function of exposure to successive linear array portions. - View Dependent Claims (12, 13, 14, 15)

24. 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 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, and wherein the visual images from the writing surface and second area are not portions of a single image; and
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. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31, 32, 33, 34)
