Abstract
A small hand-held optical scanning device for the accurate and precise scanning of lines of text characters is described. The scanner does not require any mechanical means of providing tachometer-like or encoder-like scanning signals in order to establish an accurate reproduction of the scanned text. An auxiliary single element detector samples the scanned text at an advanced (retarded) position relative to the main one dimensional scanner of the device. This advanced detector sensor, together with appropriate and disclosed software algorithms, permits the accurate correction of baseline imperfections as well as corrections for scan-speed non-uniformities and basic scan-speed errors. The processed scanner output is sufficiently faithful to the scanned text that optical character recognition (OCR) software can precisely interpret the scanned images and subsequently provide an accurate ASCII representation of the scanned text. Arbitrary characters, such as Kanji symbols, can be scanned accurately, which also permits the application of optical character recognition (OCR) software which is dedicated to such text characters.
