How C Pen Works

As C Pen is moved over the text, C Pen's internal light
source illuminates the characters and a camera takes
pictures of the text. These images are transformed to
computer-readable text by an OCR-system.
What is OCR?
Optical Character Recognition is the process of turning
an image into computer-readable text. During OCR,
C Pen analyzes the images taken by its camera and
translates them into text characters. After OCR, you can
transmit the resulting text to your PC and use it in your
Windows applications.
However, you cannot always expect C Pen to achieve
100 % correct character recognition. The result depends
on a number of circumstances:
• The quality of the printed text you want to read with
C Pen. You can calibrate C pen to optimize its
performance under difficult conditions. See Calibra-
tion under Settings/Text Quality, p. 32. High-quality
printed text produces, of course, maximum OCR
accuracy. With lower-quality pages, e.g. poor fax
copies, OCR accuracy will be poorer.
• How you hold and move C Pen over the original text.
Please read the Quick Start folder to learn how to use
C Pen correctly. It is crucial that you follow these
instructions in order to get optimal results.
• The language of the text C Pen is reading. The text
language should be set in Settings.
