I don't know if it was based on that, but a co-worker had a point-and-shoot digital camera a few years back (2009~2010) that had a similar feature for taking photos of black-/white-boards

I had a Canon P&S that did this in 2003 or so. It was nice - whiteboard mode was used after every meeting.

Some other apps that do this:

Office Lens: http://research.microsoft.com/en-us/news/features/officelens... - imports to OneNote and does OCR
