The canon_dr sane backend already has a deskew option. It is a
software implementation, as only the most expensive Canon machines
have hardware deskew.
I might be able to borrow from the canon driver, if it has a
compatible license with sane, and the source is truly included. Do you
have a link?
In the meantime, the brightness and contrast controls provided by the
backend might help.
