Optimal Reading Conditions

C-Pen uses Optical Character Recognition (OCR) to read text. OCR is the process of turning an image of characters into computer-readable text.

As C-Pen moves over the text, its internal light source illu- minates the characters and a camera takes pictures of the text. During OCR, C-Pen analyzes the pictures taken by its camera and translates them into text characters.

The OCR quality will depend on the reading conditions. The letters most commonly confused using OCR are:

e →	c	l →	I	t →	c
r+n →	m	i →	l	c →	o

The following conditions affect the quality of character recognition:

•The print quality of the text

High-quality printed text naturally gives maximum OCR accuracy. With lower-quality print, e.g. faxes, OCR accuracy may be poorer. You can calibrate the C-Pen to optimize its performance under difficult conditions; see Calibration, p. 56.

Please note that C-Pen only recognizes machine-printed

!characters such as laser-printed or typewritten text. C-Pen does not recognize handwritten text.
