NAME
       sane-stv680 - SANE backend for STV680 camera's

DESCRIPTION
       The  sane-stv680	 library  implements  a SANE (Scanner Access Now Easy)
       backend that provides access  to	 some  STV680  cameras.	 This  backend
       should  be  considered  beta-quality  software! STV680 cameras are sold
       under various brands like Aiptek.  This backend may or may not  support
       yours.

       The cameras that should work with this backend are:

       Vendor Model		 USB vendor id	USB product id	status
       ------------------------	 -------------	--------------	--------
       AIPTEK stv680		    0x0553	   0x0202	basic
       Konica e-mini		    0x04c8	   0x0722	untested
       DigitalDream l'espion XS	    0x1183	   0x0001	untested
       Creative WebCam Go mini	    0x041e	   0x4007	untested

       For all these cameras, see the backend home page (under AUTHOR) for the
       exact status of each camera.

       For startup of this backend check that if  present  the	stv680	kernel
       module is removed or disabled.
       Also    before	 using,	   enable   the	  backend   by	 editing   the
       /etc/sane.d/dll.conf file, change #stv680 to stv680.

       For problems with the untested cameras, you should contact  the	author
       for that.

       The options the backend supports can either be selected through command
       line options to programs like scanimage	or  through  GUI  elements  in
       xcam. For both programs use the -B option needed for size buffer.

       Some frontends examples:
       xcam
	      xcam -B

       scanimage:  for	writing	 in batch mode to a file or to a new file each
       time.
	      scanimage -B -d stv680:libusb:001:002  --batch=out.ppm  --batch-
	      count 5 --mode "Color RGB"
	      scanimage -B -d stv680:libusb:001:002 --batch=out%d.ppm --batch-
	      count 5 --mode "Color RGB"

       If you have any success with a camera not listed here, or if  you  have
       any strange behavior, please report to the backend maintainer or to the
       SANE mailing list.

       Valid command line options and their syntax can be listed by using
	      scanimage --help -d stv680

       Scan Mode

       --mode selects the  basic  mode	of  operation  of  the	webcams	 valid
	      choices.

	      The  read	 resolution  mode  is  8 bits, output resolution is 24
	      bits.  Selects the resolution for a scan.	  The  camera  can  do
	      only the resolutions listed.

       --Raw  In this mode raw data is displayed

       --Color
	      In this mode the bayer unshuffle is done but no color correction

       --Color_RGB
	      Bayer unshuffle, color correction

       --Color_RGB_TXT
	      Bayer  unshuffle,	 color correction, textline with date and time
	      is added

       Enhancement options

       --white-level-r
	      Selects what red radiance level should  be  considered  "white",
	      when  scanning  some  sheets  by	changing the calibration value
	      loaded into the scanner. Scale -32 .. 0 .. +32 in steps of 1.

       --white-level-g
	      Selects what green radiance level should be considered  "white",
	      when  scanning  some  sheets by changing the calibration i value
	      loaded into the scanner. Scale -32 .. 0 .. +32 in steps of 1.

       --white-level-b
	      Selects what blue radiance level should be  considered  "white",
	      when  scanning  some  sheets  by	changing the calibration value
	      loaded into the scanner. Scale -32 .. 0 .. +32 in steps of 1.

CONFIGURATION FILE
       The	 configuration	      file	  /system/resources/sane-back‐
       ends/1.0.18/etc/sane.d/stv680.conf  supports  only one information: the
       device name to use (eg usb 0x.... 0x....).

FILES
       /system/resources/sane-backends/1.0.18/lib/sane/libsane-stv680.a
	      The static library implementing this backend.

       /system/resources/sane-backends/1.0.18/lib/sane/libsane-stv680.so
	      The shared library implementing this backend (present on systems
	      that support dynamic loading).

ENVIRONMENT
       SANE_DEBUG_STV680
	      If  the  library	was  compiled with debug support enabled, this
	      environment variable controls the debug level for this  backend.
	      E.g.,  a	value  of 128 requests all debug output to be printed.
	      Smaller levels reduce verbosity.

LIMITATIONS
       The windows TWAIN driver has many more options than this SANE  backend.
       However	they  are  only software adjustments. This backend only imple‐
       ments what the webcam can support.

BUGS
       Plenty. Parts of this backend are still under development.
	      1. Some untested cameras.
	      2. Video streaming slow and stops sometimes (scanimage).
	      3. Sometimes 1/3 of image is NOK (xcam).
