Patent Images

1. For use in a process for recognizing characters on at least one document of a plurality of documents, the method comprising:

  • scanning at least a portion of said document to produce scan data signals reflecting the presence of character elements at particular positions on the document;

    storing said scan data signals;

    applying a recognition algorithm to the stored scan data signals;

    developing first identity signals representing each character recognized by said algorithm;

    presenting simultaneously in side-by-side adjacent positions imaged of a group of characters which failed recognition by said algorithm to a specified confidence level and wherein a plurality of images of said group of characters are taken from different lines of the same document or from different documents;

    said plurality of images of said group of characters being developed by scan data signals; and

    determining by inspection the identity of characters failing recognition to the specified confidence level and represented by said simultaneously-presented images.
