Thinking about the calibration routine for my scanner (Canon FB630U),
seems to me this is probably a common issue.
There's a black and a white scannable area inside the housing of my
scanner. It looks like I need to convert scans of these areas under 3
different lighting conditions into the per-ccd-element gain/offset
tables. ("Looks like", because that's what the Windows driver seems to
do.)
Anyone's scanner do something similar? Got code or math I can steal?
