Hi. Sorry if this is the wrong newsgroup.
I've got a Mustek 1200 UB Plus (cheap and cheerful) scanner. I've
successfully got it running under Linux with Sane with no real
problems.
However, I've tried a few scans and keep getting the same profile
across the scanner image (pinkish streaky lines in certain parts when
scanning a uniformish white piece of paper). I'm guessing that this is
because of a non uniformity in the scanner head as it is always in the
same place along the length of the image.
Does anyone know of any way of compensating for the streaks via some
sort of calibration (I think this would be a deconvolution if my
memory of school maths is anything to go by (increasing the gain for
certain colours for the faulty lines say)).
I know that it is possible to use graphics packages to compensate for
this later on down the line. However, this would be a pain as my
photos will not always be placed in the same point in the scanner. It
seems to me that it is more natural to do this type of compensation in
the scanner side.
Is there a way of doing this (with Linux). As my scanner was cheap (40
GBP) I can't expect much of it. However, it would be nice if there was
another way around.
Thanks,
Pete
