hello,
|
|
<BR>
|
|
<P>i am running out of sources here. since there are experts
|
|
<BR>
|
|
here, i am going to throw this up and would appreciate any
|
|
<BR>
|
|
help andor pointers.
|
|
<BR>
|
|
<P>i am running sane 1.0.1 with xsane (nice! btw) and gimp:
|
|
<BR>
|
|
<P>Vendor: HP Model: C1750A Rev: 3226
|
|
<BR>
|
|
<P>this scanner was running fine and now, after some moving and
|
|
<BR>
|
|
some period of rest in storage, it displays a "phantom" image
|
|
<BR>
|
|
slightly shifted from the original.
|
|
<BR>
|
|
<P>just to double check, went to windows and it happens
|
|
<BR>
|
|
there too, so i suspect it is a hardware problem
|
|
<BR>
|
|
regarding some sort of alignment or calibration.
|
|
<BR>
|
|
attached i am sending two small samples to illistrate.
|
|
<BR>
|
|
basically, strong color edges "bleed"
|
|
<BR>
|
|
<P>i played around a bit with gamma, and there are some
|
|
<BR>
|
|
settings that minimize this, but the image always sows
|
|
<BR>
|
|
some lack of "depth" - a contrast autostretch and/or hsv
|
|
<BR>
|
|
autostrectch always brings the bleeding back.
|
|
<BR>
|
|
<P>is this problem fixable in software?
|
|
<BR>
|
|
under linux?
|
|
<BR>
|
|
is it fixable at all?
|
|
<BR>
|
|
<P>the hewlett-packard site has very little info on these
|
|
<BR>
|
|
scanners (or on realigning or recalibrating them). i also
|
|
<BR>
|
|
search the web to no end about this issue. the h-p site
|
|
<BR>
|
|
does mention that one should "lock" the scanner head
|
|
<BR>
|
|
before moving it around, which i believe was not done when
|
|
<BR>
|
|
it was moved stored.
|
|
<BR>
|
|
<P>on a related issue, i just noticed that the windows scanning
|
|
<BR>
|
|
software, "windows imaging, by kodak", would get a noticeably
|
|
<BR>
|
|
"better looking" picture, compared to "autoenhance" in xsane
|
|
<BR>
|
|
(which btw, itself enhances substantially to just plain scanning
|
|
<BR>
|
|
under linux, say with xscanimage without advanced options).
|
|
<BR>
|
|
there was some mention on a new gamma setting of 2.2 when i installed
|
|
<BR>
|
|
the h-p deskscan software (2.8). would this mean i should
|
|
<BR>
|
|
autoenhance and then move the gamma slider to 2.2 for best results?
|
|
<BR>
|
|
<P>by "better" i mean that a couple of images i acquired under windows
|
|
<BR>
|
|
improved very verly little with contrast autostrecth and/or
|
|
<BR>
|
|
hsv autostretch.
|
|
<BR>
|
|
<P>any and all help appreciated for both issues!
|
|
<BR>
|
|
<P>thanks a lot,
|
|
<BR>
|
|
<P>-carlos
