sane-canon - SANE backend for Canon SCSI scanners
|
|
|
|
|
|
</PRE>
|
|
<H2>DESCRIPTION</H2><PRE>
|
|
The <B>sane-canon</B> library implements a SANE (Scanner Access Now Easy)
|
|
backend that provides access to the following Canon flatbed and film
|
|
scanners:
|
|
|
|
CanoScan 300
|
|
CanoScan 600
|
|
CanoScan FB620S
|
|
CanoScan FB1200S
|
|
CanoScan FS2700F
|
|
CanoScan FS2710S
|
|
|
|
Parallel port and USB scanners are not supported by this backend; see
|
|
the manual pages for <B><A HREF="sane-canon_pp.5.html">sane-canon_pp(5)</A></B> and <B><A HREF="sane-canon630u.5.html">sane-canon630u(5)</A></B> for further
|
|
information.
|
|
|
|
IMPORTANT: This is beta code. We tested the code on the scanners listed
|
|
above, using the computers and operating systems available to us, but
|
|
we cannot guarantee that the backend will work smoothly with future
|
|
operating systems, SCSI adapters, SANE frontend programs, or Canon
|
|
scanners not contained in the list above. In some cases your computer
|
|
might even hang. It cannot be excluded (although we consider it
|
|
extremely unlikely) that your scanner will be damaged.
|
|
|
|
That said, TESTERS ARE WELCOME. Send your bug reports and comments to
|
|
Manuel Panea <I><mpd@rzg.mpg.de></I>; for questions concerning the FB620 and
|
|
FB1200S contact Mitsuru Okaniwa <I><m-okaniwa@bea.hi-ho.ne.jp></I>, for the

<H2>TIPS (FS2700F)</H2><PRE>
|
|
Scanning either slides or negatives has been found to require rather
|
|
large gamma corrections of about 2.2 to 2.4 (same value for red, green,
|
|
and blue). It is recommended to use the automatic exposure controls of
|
|
the frontend <B><A HREF="xsane.1.html">xsane(1)</A></B> for best results.
|
|
|
|
The "Auto Focus" function triggers a special pass to determine the
|
|
focus value. After that, the real scanning pass takes place.
|
|
|
|
Even with "Auto Focus" turned on, the scanned image is often a bit too
|
|
blurred. Using the <B><A HREF="gimp.1.html">gimp(1)</A></B> to do a "Filter->Enhance->Sharpen" at about
|
|
40 to 60 improves the image considerably.
|
|
|
|
|
|
</PRE>
|
|
<H2>TIPS (FS2710S)</H2><PRE>
|
|
Gamma corrections are done not by the scanner, but by the backend. The
|
|
scanner is always run in 12-bit mode. In "color" mode the image data
|
|
are corrected for gamma, shadow point, etc., and then truncated to
|
|
8-bit intensities; the default gamma value is 2.0. In "raw" mode the
|
|
image data are exported without corrections as 16-bit intensities; this
|
|
mode can be recommended if extensive adjustments have to be made to a
|
|
picture (and if the frontend can handle 16-bit intensities).
|
|
|
|
Negatives are handled by simple color inversion and will require manual
|
|
removal of blue discoloration.

<H2>ENVIRONMENT</H2><PRE>
|

<B>SANE_DEBUG_CANON</B>
|
|
If the library was compiled with debug support enabled, this
|
|
environment variable controls the debug level for this backend.
|
|
Higher debug levels increase the verbosity of the output.
|
|
|
|
Example: export SANE_DEBUG_CANON=4
