Single read station acquisition for character recognition

Abstract From the Canadian patent

Abstract of the Disclosure, To read characters printed on a document it is transported beneath a self-scan photocell array extending substantially the entire width of the document. Output signals from the photocells of the array are scanned by a plurality of channels, amplified and converted into a digital data format representing the character patterns. The digital data is then processed to memory electronics and search electronics to select lines of character pattern data for transmission to a character recognition unit. The search electronics compresses the character data into search segments to evaluate the top and bottom position of character lines. Further the search, electronics …
