Using OCR zones
OCR
(Optical Character Recognition) is the mechanical or electronic
translation of images of typewritten or printed text (usually captured by a
scanner) into machine-editable text.
OCR setup allows you to define:
• the name of the OCR zone
• the physical location where you find the text (zone location on the image)
• the level where you can find the text (batch or document level)
Use the Bar Code and OCR Setup function on the Capture tab on the Job
Setup dialog box to set up the bar code reader to read one or more bar codes
or OCR parameters for one or more OCR zones.
The OCR zone separation setting on the Capture tab in the Job Setup dialog
box allows you to scan an image into the OCR window and define zones and
OCR zone-specific properties.
NOTE: The components of the Bar Code and OCR window, icons and context-
sensitive menu are described in detail in the sections entitled, “Bar
Code & OCR window” and “Bar Code and OCR windows - context-
sensitive menu” earlier in this chapter.
OCR indexing uses local language lexicons and allows reading of
alphanumeric text at high speed (1000 characters/second). It is zonal (similar
to bar code reading) and is processed during scanning.
Capture Pro Software supports the following text information for OCR:
- Ligatures (“joined” characters)
- Broken characters
- Degraded characters
- Text from 200-600 dpi resolution
- Text fonts from 8-72 points
- Numbers from 0-9
- Letters from A-Z and a-z
- Symbols ! " $ % & ( ) * + , - . / :, ; < = > ? @ [ \ ] { } £ • ß ´ ª
• For best results, use 300 dpi resolution and 12-point sans serif font (or
larger if using resolutions lower than 300 dpi). Do not use skewed
documents.
