You will have to head for a OCR (Optical Character Recognition) library. This is a pretty complex procedure, I believe you wouldn't be asking this question if you knew any way to implement this by yourself.

A quick Google yielded this result, maybe it's of help for you: http://www.planet-source-code.com/vb/scripts/ShowCode.asp?txtCodeId=1623&lngWId=7

Take a look at my answer about NeuroVCL OCR here. There is a lot of useful info and sample Delphi OCR DCU components.
