Camera phones as scanners.

Camera phones as scanners? So what’s the big deal? Modern digital cameras nowadays can do this very easily. Just snap a page at 5 megapixel resolution and what do you get? A scanned image of the page. Pfaff!

 As a page is being scanned the OCR software takes dozens of still images of the page and effectively merges them together using the outline of the page as a reference guide. The software can also detect the curvature of the page and correct any distortion so caused, enabling even the areas near the binding to be scanned clearly… Using the new software with a 1-megapixel camera held at least 20centimetres away, an A4 sized page takes about 3 to 5 seconds to scan. This produces between 21 and 35 images which the software merges together to extract the text and record any images.
