Hi,
|
|
<BR>
|
|
<P>First, I am new to this list and to sane, so feel free to point me to the
|
|
<BR>
|
|
obvious.
|
|
<BR>
|
|
<P>Second, a little background about what I am trying to do. When I was young
|
|
<BR>
|
|
my parents and I did a 8 years (1978-1986) long trip around the
|
|
<BR>
|
|
world (in a 41 feet boat). About 3000 slides have been taken, but they
|
|
<BR>
|
|
haven't been stored properly and deteriorate rather fast (moisture [?] on
|
|
<BR>
|
|
most of them). I plan to at least take a digital snapshot of them. I know
|
|
<BR>
|
|
that the color and the quality of the original will be lost, but at least
|
|
<BR>
|
|
something will stay.
|
|
<BR>
|
|
<P>I grabbed a LS-1000 (which is not the best scanner for the job) and made a
|
|
<BR>
|
|
few tests. Unfortunately, it looks like gamma correction is not supported
|
|
<BR>
|
|
from sane. I spent a couple of hours hacking the sources of the backend
|
|
<BR>
|
|
yesterday, and it looks like gamma was suported but get losts in various
|
|
<BR>
|
|
changes for the other scanners.
|
|
<BR>
|
|
<P>So, the real questions:
|
|
<BR>
|
|
<P>1/ Can I find detailed specs of LS-1000 (in particular, the SCSI
|
|
<BR>
|
|
commands it supports) ?
|
|
<BR>
|
|
<P>2/ I _think_ I have read somewhere that the LS-1000 is 12 bits
|
|
<BR>
|
|
internally. Am I right to beleive that there must be a way to send a 4096
|
|
<BR>
|
|
entries Look Up Table to the scanner before the scan ?
|
|
<BR>
|
|
<P>3/ Can someone explain me what a pre-scan is (I guess that it is a pass
|
|
<BR>
|
|
over the slide that the firmware of the scanner uses to set various scan
|
|
<BR>
|
|
parameters to reasonable values) ?
|
|
<BR>
|
|
<P>4/ I plan to do a little tool that do "autofocus + low-res scan + compute
|
|
<BR>
|
|
black/white point + create a LUT table with user-defined gamma + scan
|
|
<BR>
|
|
the slide" as a poor man batch scanner. Would it be usefull ?
|
|
<BR>
|
|
<P>5/ I plan to buy a LS-2000 before doing te real scans. Do the infra-red
|
|
<BR>
|
|
correction functions of the 2000 are correctly handled by sane ?
|
|
<BR>
|
|
<P>Sorry for the long mail, thanks in advance for any reply
|
|
<BR>
|
|
<P>Cheers,
