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,

I believe they have machines to turn pages, and something to figure 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.
