ABSTRACT:
A scanner for reading characters from a string of characters recorded on a substrate. The scanner includes a character scanner that is used with a stroking motion parallel to the string of characters that permits the user to view the line being scanned as the scanner is moved across the page. A line-by-line scanner with a wide area of view may be mounted along the side of the scanner to be used in scanning a page or column on a line-by-line basis. The character scanner may include a lens of variable magnification so as to accommodate variable size print. A microphone mounted on the scanner permits the input of voice sound information. The scanner may be in communication with a computer through a cable or a wireless transmitter/receiver. The value of each pixel detected by the scanner is determined by comparing the light reflection value with a threshold that is adjusted in accordance with the values of pixels detected and averaged over previous frames. The hand-held scanner may be housed in any elongate housing for pen-like use or in a palm-held housing such as a typical mouse. An image splitter may be included within the optics to generate two separate images for separate character recognition processing.
