Introducing Visioneer Pro
OCR 100
This chapter introduces you to the Pro OCR
application and to the concept of optical character
recognition (OCR).
Why Pro OCR
Pro OCR is an Optical Character Recognition (OCR)
application. An OCR application converts images of
text, such as those obtained from scanning a
document or receiving a fax through your faxmodem, into editable text. For example, when a
scanner scans a page of text, it sees black and white
areas on the page. The scanner converts what it sees
into an image and stores the image on the computer.
To transform a scanned text image into something a
word processing or spreadsheet application can
recognize as characters, you need an OCR (optical

character recognition) application, such as Pro OCR.
Every day you may spend a lot of time retyping
printed text or numbers from hard copy documents.
By using Pro OCR and a scanner as an input device,
you can eliminate much of this retyping.
Features and Highlights of Pro OCR
Many of the existing OCR products are typically
capable of recognizing 200–300 plain, nonstylized
typefaces. Using recognition technology, Pro OCR
can recognize over 2,000 typefaces.
Most basic OCR applications inspect the scanned
page image, attempt to recognize the dots on the page
as characters, and transform the image into a plain
text file. Pro OCR does all of these basic tasks, but it
can also get the entire page into your word processor
or spreadsheet as is—retaining the shape, form, type,
and spacing, as well as the content, of the input page.
Pro OCR provides:
■ The ability to read one or more pages of
text including graphics. Pro OCR reads
pages directly from your scanner, or it reads
TIFF, PCX, and DCX files. Pro OCR can
automatically locate pictures and embed them
in your document. You can also export
pictures separately in a number of file formats.
■ Speed and accuracy of recognition. With
most documents, Pro OCR is faster than, and
as accurate as a good typist.
■ Numeric regions. You can specify that a
given region on a page can contain only
numbers. Numeric regions help Pro OCR
make sure that numbers are always recognized
as numbers and never mistakenly identified as
file:///C|/VisioneerDoc/html/ug_main.htm (2 of 3) [1/20/2003 4:21:10 PM]

letters.
■ Recognition and retention of fonts,
characters, styles, and page formatting. Pro
OCR recognizes and retains the differences
between serif and sans-serif fonts, styles such
as bold, underline, and subscript, and
formatting such as columns, tables, and
indents.
■ Deferred and batch processing. You can
perform procedures that need your attention or
interaction (for example, locating), and then
do the time consuming steps that don’t need
interaction (for example, recognizing) at
another time.
■ Internet readiness. supports HTML export
format. You can convert an image file directly
to an HTML page and upload it to the Web
site.
■ Proofing options. Pro OCR has a number of
proofing options. You can also send
recognized text directly to your word
processor.
■ Save features. With Pro OCR you can save
recognized text in a wide variety of word
processor and spreadsheet file formats. Pro
OCR works with imperfect input pages that
may have skewed lines of text, touching or
broken characters, and fuzzy characters.

Glossary
A4 Letter page size An A4 size page measures 8.33" x 11.66".
accelerator key In Windows applications, a keyboard shortcut to a menu
command.
ADF See automatic document feeder (ADF).
alphanumeric word A word made up of the alphabetic and numeric characters
(A–Z, a–z, 0–9) in a character set. Excludes punctuation and
other symbol characters.
ASCII Acronym for American Standard Code for Information
Interchange (pronounced “ASK-ee”). A standard that assigns
a unique binary number to each text and control character.
ASCII code is used for representing text inside a computer
and for transmitting text between computers or between a
computer and a peripheral device.
As Single Column locating method One of Pro OCR’s three locating methods. Use it when you
want Pro OCR to read a page as a single column, from left
margin to right margin, ignoring any column or paragraph
spacing. Most commonly used for pages in which there is no
clear column or paragraph structure.
Auto OCR Clicking this button starts automatic processing, which uses
Get Page, Locate, and Recognize according to the current
gallery settings.
Auto brightness A feature of some scanners, by which brightness is adjusted
automatically while the page is scanned.
automatic document feeder (ADF) Built-in or optional equipment for a scanner that lets you
automatically scan stacks of pages instead of having to place
them one at a time on the flatbed. Sometimes it’s difficult to
control the proper alignment of pages using an automatic
document feeder. Compare with
flatbed scanner and
sheetfed scanner.
file:///C|/VisioneerDoc/html/glossary.htm (1 of 22) [1/20/2003 4:21:13 PM]
file:///C|/VisioneerDoc/html/glossary.htm
automatic processing A method for using Pro OCR with minimal intervention.
Automatic processing involves setting appropriate Gallery
settings, before using Auto Start to read in one or more image
files or scan in one or more pages. Once page images have
been acquired, automatic processing Locates and Recognizes
each page image in succession. Automatic processing is best
suited to documents that require the same Gallery settings
(Page Size, Brightness, Locate method, etc.). Compare with
single-step processing.
background noise Non-character or non-graphic information in a page image
that adversely affects optical recognition. Background noise
includes the shading that results from scanning colored paper
stock, extraneous marks, dirt or ink bleed. Problems with
background noise can be reduced by using the brightness
setting in Pro OCR to compensate for the type of noise on the
page.
backup (n.) A copy of a disk or of a file on a disk. It’s a good idea to
make backups of all your important disks and to use the
copies for everyday work, keeping the originals in a safe
place.
backwards compatible The ability of an application to open files created with earlier
versions of that application.
bit image A collection of bits in memory that represents a two-
dimensional surface. For example, the screen is a visible bit
image.
bitmap 1. A set of bits that represents the graphic image of an
original document in memory.
2. A set of bits that represents the positions and states of a
corresponding set of items, such as pixels. Used by the
computer to construct graphic images and fonts. See also bit
image.

file:///C|/VisioneerDoc/html/glossary.htm
bitmapped character A character image made up of a pattern of dots that exists in a
computer file or in memory as a bitmap. Bitmapped
characters cannot be interpreted by a computer. In order for a
computer to use bitmapped characters in a word processor or
spreadsheet, the characters must first be interpreted by an
OCR application and translated into ASCII text.
bold text Text with the bold attribute looks like this. See also text
style.
brightness The relative amount of light or darkness reflected from an
image. A scanner’s brightness control is used in Pro OCR to
adjust for pages that are either too light or too dark.
broken character A character with one or more missing pieces, such as a
missing serif, stem, or cross bar. For example, a broken lower
case ‘e’ might not have a fully closed loop, which could
cause it to be misrecognized. Problems with broken
characters can be reduced by using the brightness setting in
Pro OCR to darken the image when scanning. Compare with
heavy character and touching characters.
built-in dictionary The dictionary that Pro OCR automatically loads and uses
whenever Recognize is done. The built-in dictionary is used
to enhance Pro OCR’s recognition accuracy and also to find
misspelled words in the document. Compare with
supplementary dictionaries and user dictionary.
CCITT Abbreviation for Consultative Committee on International
Telegraphy and Telephony; an international committee that
sets standards and makes recommendations for international
communication. One of the standards set by CCITT is for the
compression of image files. Pro OCR employs CCITTstandard compression methods. See also
compression and
TIFF.
character Any symbol that has a widely understood meaning and thus
can convey information, including alphabetic, numeric,
symbolic, and punctuation elements.

file:///C|/VisioneerDoc/html/glossary.htm
character format Font and style information applied to characters. Character
format information includes the font name and type size, as
attributes such as underline, bold, italic, or some combination
of these properties. Compare with page format.
character identification error An incorrectly recognized bitmapped character. There are
two kinds of character identification errors—substitutions
and rejects. A character substitution occurs when a character
is incorrectly recognized as another. A reject character results
from the inability of the OCR application to interpret a
character image with sufficient confidence. In such cases,
recognition is not attempted and the character is flagged as
illegible. Compare with
layout analysis error.
character image An arrangement of bits that defines a character in a font.
character recognition The OCR process in which bitmapped character images are
interpreted and translated into ASCII computer codes.
character style See
type style.
clipboard In Windows applications, temporary storage for text that is
cut or copied from a document. Text saved in the clipboard
may be pasted back into the same or another document.
column information Part of Pro OCR’s page format information. Column
information includes the location of the column on the page,
the width of the column, and its left and right margins.
compression Electronic method for reducing the size of a file without
losing any information in the file. Compressed TIFF files
take up significantly less disk space than uncompressed files.
See also
TIFF and CCITT.
confidence In Pro OCR, a measure of the certainty of an unknown
character’s identity. Above a certain confidence level, a
character is automatically recognized. At lower confidence
levels, a character may either be recognized, but flagged as a
suspect character, or not recognized and flagged as an
illegible character.
file:///C|/VisioneerDoc/html/glossary.htm (4 of 22) [1/20/2003 4:21:13 PM]
file:///C|/VisioneerDoc/html/glossary.htm
consistent document A set of pages or image files where the same Gallery settings
apply to each page in the document. Pro OCR’s Auto Start
feature can be used to best effect when a document is
consistent.
copyrighted document Most published or printed materials and documents are
copyrighted. It is illegal to use a computer and Pro OCR to
copy, store, or reproduce, on paper or electronically, any
copyrighted documents without the permission of the
copyright holder.
deferred job A file that contains one or more partially processed pages for
Pro OCR to finish processing later on. See also Pro OCR
Deferred format and deferred processing.
deferred processing Provides the ability to individually specify Get Page, Locate,
and recognize settings for particular pages when necessary,
while still being able to automatically process a job at a later
time.
degraded image An image that contains broken characters, touching
characters and/or background noise. See
broken character,
touching characters and background noise.
dialog box In Windows applications, the standard pop-up box that is
displayed to communicate with the user when a command
requires some further action. Some dialog boxes are
informational.
desktop Your working environment on the computer—the menu bar
and the background area on the screen. You can have a
number of documents or windows on the desktop open at the
same time.
document area The main part of the application window in Pro OCR. The
document area shows one page of the current document at a
time using the selected View Size setting.

dots per inch (dpi) A measure of the visual resolution of a display or output
device. Monitor screens typically have resolutions in the
range of 70 to 75 dpi. Most common laser printers have a
resolution of 300 dpi. The lower the resolution of a page in
dots per inch, the lower the visual quality of characters on
that page. Pro OCR can quickly and accurately recognize
characters scanned in at resolutions down to 200 dpi.
dpi See
dots per inch (dpi).
draft quality text On 9-pin dot matrix printers, the low resolution printing
option. Draft quality text is monospaced and made up of
visible dots that do not touch. In Pro OCR, click the Draft
Quality button in the Recognize section of the Gallery, to
improve recognition on draft quality dot matrix text.
Compare with
letter quality text.
driver See
scanner driver.
exporting Saving a document in an external format, such as a word
processor, spreadsheet, text or standard image file. An
exported document is created for use outside of Pro OCR.
export format Pro OCR can save and export documents in a variety of
specific word processor and spreadsheet formats. The
specific export format is specified in the Save As dialog box.
file extension In the MS-DOS operating system, file names conventionally
consist of a base and a file extension, for example
SAMPLE.TXT. In this example, “SAMPLE” is the base, and
the file extension is “.TXT”. File extensions are used to
identify the type of file. In this example, the file extension
indicates that this is a text (ASCII) file.
file formats See
input file formats and output file formats.
file type Different applications create different file types. Some file
types are application-specific. Other file types are generic.
The file type indicates what kind of information is contained
in the file and what format the information is in. Most
applications can only open files of certain file types.
file:///C|/VisioneerDoc/html/glossary.htm (6 of 22) [1/20/2003 4:21:13 PM]
file:///C|/VisioneerDoc/html/glossary.htm
fine resolution A term associated with FAX modems, referring to the highest
resolution of the image files typically produced by these
devices. Fine resolution is approximately 200 x 200 dpi,
which is adequate for reliable recognition.
flatbed scanner Scanner with a glass plate on which pages are placed face
down. Although such scanners can only read one page at a
time, they can support a variety of paper sizes and it’s easier
to control the proper alignment of a page. Compare with
automatic document feeder (ADF) and sheetfed scanner.
font All characters (letters, numbers, and symbols) in one size and
style of a font family. 12 point Helvetica Bold Italic is a font.
“Font” is sometimes incorrectly used instead of “font family”
or “typeface.” See also
font family and typeface.
font family The complete set of variations of a particular typeface. For
example, Helvetica is a font family. It contains a variety of
typefaces including, for example, Helvetica, Helvetica Bold,
Helvetica Italic, Helvetica Bold Italic. See also
font and
typeface.
font mapping Set in the Display Options dialog box. Tells Pro OCR which
fonts to use to display recognized text. Also specifies which
fonts to use in documents that are exported to Windowsbased word processors.
format retention The ability to retain the layout of a page, including margins,
paragraph and column widths, and tabs and indents. Pro OCR
preserves as much page format information as export formats
support.
Gallery The Pro OCR toolbar. All settings for the Get Page, Locate,
and Recognize stages of the Pro OCR process are set in the
Gallery. Common Pro OCR processes—Auto Start, and
single-step Get Page, Locate, and Recognize—can be
initiated from the Gallery.
Get Page Single-step Gallery function. It is also the first stage of the
Pro OCR process. Scans one page from a scanner or reads

grayscale image An image format where individual pixels can be expressed
with more than a single bit, allowing the image to contain
true shades of gray. Pro OCR will not open grayscale images.
Compare with single-bit image.
hard page breaks Special formatting that you put in manually in a text or word
processor document. Most word processors and text editors
automatically create soft page breaks unless you explicitly
specify hard page breaks. In Pro OCR, you can force the
output application to preserve the page breaks of the input
document by clicking the “Insert Hard Page Breaks”
checkbox when you are in the Save As Options dialog box.
heavy character In Pro OCR, a character that is printed too dark or thick, so
that the representation obscures detail and reduces confidence
in the identity of that character.
I-beam pointer A mouse pointer shape that resembles an upper-case “I”.
When the pointer has this shape, you can select text. See also
insertion point.
icon An image that graphically represents an object, a concept, or
a message. Screen icons can represent disks, documents,
application programs, or other things you can select and
open. In an application such as Pro OCR, icons are also used
to represent various settings in the gallery, Style ribbon, and
Status bar.
illegible character A character that Pro OCR cannot recognize with adequate
certainty. Illegible characters in a document are highlighted
and displayed with the specified illegible character symbol in
the text view. See also
suspect character.
illegible character symbol The symbol Pro OCR uses to display illegible characters in
the text view. Set in the Display Preferences dialog box. See
also
illegible character.
image view The view that displays the bitmapped image of a page. Used
to locate regions of text or graphics, and for viewing the
original scanned image of a page during proofing and editing.

input file formats Pro OCR can read documents saved by other applications in
TIFF, PCX and DCX formats, as well as those documents
saved in its own proprietary TIFF format. See also
PCX and
TIFF.
insertion point The place in a text file where text is inserted or deleted.
Indicated by a blinking vertical bar.
italic text Text with the italic attribute looks like this. See also
text
style.
justification Alignment of text to the left, right, or both margins of a
column or page. Text may be left-justified, right-justified,
center-justified, or fully justified (both left- and rightjustified). Pro OCR preserves justification.
kerning A measure of the spacing between characters. In tightly
kerned text, the letters are very close together, which can
cause letters to touch when the page is scanned. See also
touching characters.
landscape orientation When you hold a page of text to read it, it is in landscape
orientation when the page is wider than it is tall. Compare
with
portrait orientation.
layout The relative position of elements on a page, such as margins,
columns, graphics, titles and sections.
layout analysis error The result of an OCR product’s inability to correctly organize
recognized text into words, lines and paragraphs on the page.
There are two kinds of common layout analysis errors—
incorrectly interpreting the flow of text on a page and
incorrectly grouping or separating side-by-side paragraphs.
Layout analysis errors can be more troublesome than
character identification errors, particularly with documents
having complex layouts. Compare with
character
identification error.

Lenient suspect threshold Tells Pro OCR to only highlight suspect characters it is very
uncertain of. Very few characters are marked as suspect,
compared to when the suspect threshold is set to normal or
stringent. Use it when you’re dealing with documents
containing fonts that you know from experience have been
recognized accurately or when you’re less concerned with
double-checking. Set in the Display Options dialog box.
Compare with
Normal suspect threshold and Stringent
suspect threshold.
letter quality text Text made up of characters that are fully formed with dots
that are touching. Compare with
draft quality text.
line break The point at the edge of a line of text where the text flows
onto the next line.
Locate Single-step Gallery function. It is also the second stage of the
Pro OCR process. Specifies which text will be recognized on
a page by creating or applying locate regions on the page
according to the current Locate and Pictures settings. The
current Locate setting may be either Normal, As Single
Column, or Template. The current Pictures setting may be
Locate Text and Pictures or Locate Text Only.
locate region Defines an area on the page image in the image view and the
text view. The text and picture kinds of locate regions may be
defined automatically or manually. All three types of locate
regions may be manually defined using the locate region
drawing feature, or may be recalled using the Template
locating method. See also
text region, numeric region,
picture region, and Template locating method.
locating The process in Pro OCR for specifying which locate regions
will be recognized on a page by creating or applying locate
regions on the page.
locating method Tells Pro OCR how to locate regions for processing on a
page. The three locating methods are Normal, As Single
Column, and Template. See also
Normal locating method,
As Single Column locating method, and Template locating
method.
