Hi!
Just tried this Sunday...
6MP digital SLR camera + tripod is good enough to make images of book
pages for OCR. Speed is ~ 10-15 seconds per page.
However, if you want good quality images, you should use regular
scanner, adjust page position, press book.

We had a discussion at a recent Wikimedia UK board
meeting about potentially
buying some digitisation equipment which could be used to generate content
for the Wikimedia projects. This recent email to the EN-WP list sparked my
interest.
Does anyone have any experience with equipment like this, and could you
recommend anything? Any idea what the price range and quality typically is?
Also, is anyone else in the Wikimedia community currently doing this?
Thanks,

out the distorted photo of the book and render it how it would look as
a flat page.
Yeah, there are videos of these machines. The book sits open, the
scanner comes down and scans both open pages at once. As it goes up
again, it sucks on one page, causing it to flip over. Then repeat.
Oh, look, here you go:
