OCR (Optical Character Reader)
Device for reading characters optically. System for extracting
information in a text format from information in the form of a
graphic such as hand-written or printed characters which have
been scanned with a scanner. You cannot edit text scanned with a
scanner because it is in a graphic format, but with OCR software
you can convert to a text file and then edit the text with word-
processing software.
