Appeal No. 95-5009
Application 08/162,367
Claim 11 reads as follows:
11. A computer-implemented method of retrievably
storing contents of a plurality of documents having images
imprinted thereon comprising
optically scanning the documents to generate electrical
signals forming a digital representation of the images on the
documents,
storing the signals forming the digital image
representation of each document,
establishing a font table in memory including signals
forming images of characters in a plurality of different fonts,
the signals for images of each character of each font having a
unique, identifiable location in a memory area,
selectively recognizing and converting groups of
characters from signals forming the digital representations of
the images into signals representing computer readable code,
storing signals forming images of characters which are
not recognizable and convertible as ambiguous characters in
unique, identifiable locations in the font table,
searching for a document by the steps of
selecting a search word,
constructing signals forming an image of the selected
search word by copying signals representing individual characters
from the font table in at least one font,
comparing the signals forming the constructed search
word image with signals forming the image representations of
scanned and stored documents until a match is found,
selecting images of the ambiguous characters for use in
search word images, and
repeating the step of comparing including comparing
signals representing images of ambiguous characters with stored
