Abstract
Abstract An optical character recognition screen editing process is performed efficiently and only when necessary. The process is ordered so that editing is performed in increasing order of work intensity. That is, less "expensive" (i.e., less time consuming) correction methods are performed first, as a filter for more "expensive" correction methods. In the preferred embodiment, individual character are corrected first, information fields are corrected second, and entire forms are correction last. Preferably, the individual characters may be collected from a number of forms before being displayed for correction.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
110 words
A method for manually editing a plurality of optically scanned documents, comprising the steps of: a. determining if characters on the optically scanned documents are not recognized; b. accumulating a plurality of unrecognized characters from the documents; c. displaying together the accumulated unrecognized characters; d. manually editing the unrecognized characters; e. performing a first integrity check on: (1) documents having manually edited characters; and (2) documents not having unrecognized characters; f. performing a field edit on fields from the documents failing the first integrity check; g. performing a second integrity check on the field edited fields; and h. saving the field edited information if it passes the second integrity check.
Claim 2
Independent Claim
110 words
A method for manually editing a plurality of optically scanned documents, comprising the steps of: a. determining if characters on the optically scanned documents are not recognized; b. accumulating a plurality of unrecognized characters from the documents; c. displaying together the accumulated unrecognized characters; d. manually editing the unrecognized characters; e. performing a first integrity check on: (1) documents having manually edited characters; and (2) documents not having unrecognized characters; f. performing a field edit on fields from the documents failing the first integrity check; g. performing a second integrity check on the field edited fields; and h. saving the field edited information if it passes the second integrity check.
Claim 3
Dependent Claim
84 words
The method of claim 1, wherein the step of determining if characters on the optically scanned document are not recognized further comprises: a. classifying an optically scanned document as one of: (1) completely recognized; (2) manual editing required; and (3) rejected; b. saving the document if it is classified as completely recognized; c. performing an edit on the entire document if it is classified as rejected; and d. performing claim 1, steps b-h on the document if it is classified as manual editing required.
Claim 4
Dependent Claim
33 words
The method of claim 1, wherein the step of accumulating a plurality of unrecognized characters comprises saving in an intermediate file the unrecognized characters and information identifying the location of the unrecognized character.
Claim 5
Dependent Claim
49 words
The method of claim 1, wherein the step of manually editing the unrecognized characters further includes the steps of: a. displaying on a first portion of a monitor the accumulated unrecognized characters; and b. providing on a second portion of the monitor an area for displaying input corrected characters.
Claim 6
Dependent Claim
20 words
The method of claim 4, further comprising displaying on a third portion of the screen information about the displayed characters.
Claim 7
Dependent Claim
22 words
The method of claim 4, wherein before the step of displaying, selecting one of either only numerals and only letters for display.
Claim 8
Dependent Claim
19 words
The method of claim 4, wherein before the step of displaying, selecting a character editing screen display set up.
Claim 9
Dependent Claim
109 words
The method of claim 7, wherein the step of selecting a character editing screen display setup further comprises the steps of: a. accumulating a number of unrecognized characters; b. selecting whether the unrecognized characters are to be displayed at a uniform size; c. if the unrecognized characters are not selected to be displayed at a uniform size, arranging the accumulated characters in size order; d. if the unrecognized characters are selected to be displayed at a uniform size: (1) normalizing the unrecognized character; (2) determining an image density of the normalized unrecognized characters; and (3) arranging the normalized characters in order of image density; e. aligning the unrecognized characters.
Claim 10
Dependent Claim
38 words
The method of claim 8, wherein the step of aligning further comprises the steps of: a. calculating a center alignment for each character to be displayed; and b. determining the alignment line for each character to be displayed.
Claim 11
Dependent Claim
28 words
The method of claim 1, wherein the step of performing an integrity check further comprises comparing a field entry with predetermined information to cross-check accuracy of the entry.
Claim 12
Dependent Claim
31 words
The method of claim 1, wherein the step of performing the integrity check further comprises checking a value range of a field entry to determine if it satisfies a predetermined relationship.
Claim 13
Dependent Claim
47 words
The method of claim 1, wherein the step of field editing further comprises the steps of: a. displaying on a first portion of a monitor a rejected field; and b. providing on a second portion of the monitor an area for displaying an input corrected character string.
Claim 14
Dependent Claim
20 words
The method of claim 12, further comprising displaying on a third portion of the screen information about the rejected field.

25 words
The method of claim 12, further comprising displaying on a fourth portion of a monitor the rejected field and fields elated to the rejected field.
Claim 16
Dependent Claim
22 words
The method of claim 14, further comprising indicating characters in the rejected field and related fields that are likely to be erroneous.
Claim 17
Dependent Claim
70 words
The method of claim 1, wherein if the field fails the second integrity check, the step of field editing further comprises the steps of: a. determining if the field is either one of an independent field and a related field; b. if the field is an independent field, highlighting a name of the rejected field; c. if the field is related, displaying the rejected field and fields related to it.
Claim 18
Independent Claim
118 words
A method for displaying a number of unrecognized optically scanned images, comprising the steps of: a. accumulating a number of unrecognized characters from a plurality of documents; b. selecting if the accumulated unrecognized characters are to be displayed at a uniform size; c. if the accumulated unrecognized characters are not selected to be displayed at a uniform size, arranging the accumulated characters in size order; d. if the accumulated unrecognized characters are selected to be displayed at a uniform size: (1) normalizing the unrecognized characters; (2) determining an image density of the accumulated unrecognized characters; (3) arranging the characters in order of image density; e. aligning the accumulated unrecognized characters; and f. displaying the aligned accumulated unrecognized characters.
Claim 19
