What is OCR?
Optical character recognition (OCR) is the process of extracting text from an image of a page. This page image is an electronic picture of text and maybe other elements such as headings and pictures. Page images can result from scanning a paper document or from opening an electronic image file. You may receive these files by e-mail or from a fax machine or from your own scanner.
These images do not have editable text characters; they have many tiny dots (pixels) that together form a picture of text. The OCR process examines the text image and creates computer-editable text from it, so you do not have to retype the text manually.
OCR takes image:
and creates text: 
During OCR, OmniPage uses the settings selected in the OmniPage Toolbox to determine the text flow on a page, and creates ordered zones around areas of a page to identify what will be recognized as text or retained as a graphic. After OCR, you can save the resulting text to a variety of word-processing, page layout, and spreadsheet applications.

OmniPage only recognizes machine-printed characters such as laser-printed or typewritten text. However, it can retain handwritten text, such as a signature, as a graphic.
