@delphidb96:

Thanks for the idea, Derek. Of course, I tried this option before. I even bought a Nikon P90 to do this. It has a special mode for document photographing. It produces pretty nice results.
There are two problems:
(1) in order to finish it faster, you need a camera with a remote shutter release, otherwise it is really more of a hassle. Mine (although a very good and pricey camera) does not have this option.
(2) photographing (if you need high resolution results for future OCRing) produces HUGE files. Scanning B&W with 360dpi, a 300 page book produces (depending on the # of images in the book) a ~30MB file. Photographing produces at least many times bigger files for a equal resolution result.

I am very interested in the other method you mentioned, the webcam. I always thought of photographing with a digital camera, but have never considered photographing with a webcam before...This does not help producing bigger files, but definitely solves the remote shutter release problem. I guess bigger files can be fixed with a bigger external HDD.

Could you write the webcam that you bought, 5MP sensor for $20? And, other webcams that you considered? I would appreciate all kinds of information on your setup, maybe also a few pictures of the setup...?

Thanks in advance.

Aside from this, I am still curious and I still want to learn about the difference btw Epson and Ricoh scanning technology...
