You are wrong about dpi. Firstly, you do not use 600 dpi for OCR, unless your print is very small. Recommended dpi is 300-400 dpi, and in one of my previous posts I gave you an example how a perfect (Word print to image) picture gives better OCR results at 300 dpi rather than 400 dpi - with Finereader 8. Faxes at 200 dpi are OCRed with no problems as long as they are clean (no smudges).
Secondly, a 10 Mpixel camera gives you an equivalent of 300 dpi for A4 format and 600 dpi for A5. I refer you to a nice OPTICAL DPI TABLE in Atiz FAQ (
http://www.atiz.com/support.php). You can easily calculate it yourself as well. However, to be true, I quote below a comment by Atiz:
"It is kind of hard to compare the dpi from cameras vs. the dpi from scanners. The results from the cameras at lower dpi can be higher quality than scanners. DPI is not the total information that is equal to the quality of the image. It is just one factor of many other factors that represent quality."
I agree with them. I have used a dozen of various scanners (including sheet feeder scanners) in my work. One of them is standing idle on my desk even now, but I have no use for it. Photoscanning is fast and produces good quality results for normal home or office use.
