NAME <\/a> <\/h2>\n

sane\u2212stv680 \u2212 SANE backend for STV680 camera\u2019s<\/p>\n

DESCRIPTION <\/a> <\/h2>\n

The sane\u2212stv680<\/b> library implements a SANE (Scanner Access Now Easy) backend that provides access to some STV680 cameras. This backend should be considered beta-quality<\/b> software! STV680 cameras are sold under various brands like Aiptek. This backend may or may not support yours.<\/p>\n

The cameras that should work with this backend are:<\/p>\n

Vendor Model USB vendor id USB product id status
———————— ————- ————– ——–
AIPTEK stv680 0x0553 0x0202 basic
Konica e-mini 0x04c8 0x0722 untested
DigitalDream l\u2019espion XS 0x1183 0x0001 untested
Creative WebCam Go mini 0x041e 0x4007 untested<\/p>\n

For all these cameras, see the backend home page (under AUTHOR) for the exact status of each camera.<\/p>\n

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<\/i> file, change #stv680 to stv680.<\/p>\n

For problems with the untested cameras, you should contact the author for that.<\/p>\n

The options the backend supports can either be selected through command line options to programs like scanimage<\/b>(1) or through GUI elements in xcam<\/b>(1). For both programs use the \u2212B<\/b> option needed for size buffer.<\/p>\n

Some frontends examples:<\/p>\n

xcam<\/b>(1)<\/p>\n

xcam \u2212B<\/p>\n

scanimage<\/b>(1): for writing in batch mode to a file or to a new file each time:<\/p>\n

scanimage \u2212B \u2212d stv680:libusb:001:002 \u2212\u2212batch=out.ppm \u2212\u2212batch-count 5 \u2212\u2212mode “Color RGB”
scanimage \u2212B \u2212d stv680:libusb:001:002 \u2212\u2212batch=out%d.ppm \u2212\u2212batch-count 5 \u2212\u2212mode “Color RGB”<\/p>\n

If you have any success with a camera not listed here, or if you observe any strange behavior, please report to the backend maintainer or to the SANE mailing list.<\/p>\n

Valid command line options and their syntax can be listed by using:<\/p>\n

scanimage \u2212\u2212help \u2212d stv680<\/p>\n

Scan Mode<\/b><\/p>\n\n\n
<\/td>\n\n

\u2212\u2212mode<\/b><\/p>\n<\/td>\n

<\/td>\n\n

selects the basic mode of operation of the webcams valid choices.<\/p>\n<\/td>\n<\/tr>\n<\/table>\n

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.<\/p>\n\n\n
<\/td>\n\n

\u2212\u2212Raw<\/b><\/p>\n<\/td>\n

<\/td>\n\n

In this mode raw data is displayed<\/p>\n<\/td>\n

 <\/td>\n<\/tr>\n<\/table>\n

\u2212\u2212Color<\/b><\/p>\n

In this mode the bayer unshuffle is done but no color correction<\/p>\n

\u2212\u2212Color_RGB<\/b><\/p>\n

Bayer unshuffle, color correction<\/p>\n

\u2212\u2212Color_RGB_TXT<\/b><\/p>\n

Bayer unshuffle, color correction, textline with date and time is added<\/p>\n

Enhancement options
\u2212\u2212white\u2212level\u2212r \u221232..+32<\/b><\/p>\n

Selects what red radiance level should be considered “white”, when scanning some sheets by changing the calibration value loaded into the scanner. Scale \u221232 .. 0 .. +32 in steps of 1.<\/p>\n

\u2212\u2212white\u2212level\u2212g \u221232..+32<\/b><\/p>\n

Selects what green radiance level should be considered “white”, when scanning some sheets by changing the calibration i value loaded into the scanner. Scale \u221232 .. 0 .. +32 in steps of 1.<\/p>\n

\u2212\u2212white\u2212level\u2212b \u221232..+32<\/b><\/p>\n

Selects what blue radiance level should be considered “white”, when scanning some sheets by changing the calibration value loaded into the scanner. Scale \u221232 .. 0 .. +32 in steps of 1.<\/p>\n

CONFIGURATION FILE <\/a> <\/h2>\n

The configuration file \/etc\/sane.d\/stv680.conf<\/i> supports only one item: the device name to use (eg usb 0x…. 0x….).<\/p>\n

FILES <\/a> <\/h2>\n

\/usr\/lib64\/sane\/libsane\u2212stv680.a<\/i><\/p>\n

The static library implementing this backend.<\/p>\n

\/usr\/lib64\/sane\/libsane\u2212stv680.so<\/i><\/p>\n

The shared library implementing this backend (present on systems that support dynamic loading).<\/p>\n

ENVIRONMENT <\/a> <\/h2>\n

SANE_DEBUG_STV680<\/b><\/p>\n

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.<\/p>\n

LIMITATIONS <\/a> <\/h2>\n

The windows TWAIN driver has many more options than this SANE backend. However they are only software adjustments. This backend only implements what the webcam can support.<\/p>\n

BUGS <\/a> <\/h2>\n

Plenty. Parts of this backend are still under development.<\/p>\n

1. Some untested cameras.
2. Video streaming slow and stops sometimes (scanimage).
3. Sometimes 1\/3 of image is NOK (xcam).<\/p>\n
