I just shoot a book page with my 2MP camera of my cellphone
the only problem I encountered is that corners are blurry and dark and there is a distortion as the book page doesnt lay flat
I am quite satisfied with it, I am almost sure that we don't need too many megapixels, but sharp lens (no blurry corners, barrel distortion and dark corners) and as less as possible page curve
the flat page problem:
a glass over a bookpage doesn't seem to flaten it enough
I wonder how the
kirtas machine flatens the book pages (or how it corrects the distortion with a postprocess
operation)
what I think it does is that it shoots the photo when the bookpage is vertical:
this is the best position that the page is completely flat and there is no distortion at all
if we manage to reproduce this, to make some kind of photocopy stand that will be able to stabilize each bookpage in that position, the main (since all others seem easily correctable) problem of book scans will be solved
EDIT: some programs are supposed to fix the curve distortion of book pages, but I havent tried any yet (if needed I 'll post some links)
EDIT2: if we put a single book page between two glasses we will do the job nicely, however it will be very time consuming to do this for every page
but only books with soft cover have problem to be flaten, the hard cover books are easier to flat
