NAME

qcset - Logitech QuickCam driver configurator

qcset [device] [options] [module_parameters]

qcset is a tool for manipulating the registrers of the Logitech QuickCam camera, and the kernel module parameters.

It operates on /dev/video0 by default, but you can specify a different device as a first argument.

The val values should be between 0...65535 inclusive, 32768 is the default.

-h Display this help

-i Display camera information

-r Display all known registers of camera

-a Display all (including empty) registers of camera

-b val Set brightness (camera exposure time)

-u val Set hue (not supported with all sensors)

-o val Set color strength (increase when setting hue)

-c val Set contrast (camera gain)

-w val Set whiteness (image sharpness when quality=best)

-s r Settings read (from STDIN)

-s w Settings write (to STDOUT)

-g v Enable gamma correction with the given gamma value

-g rg:gg:bg: Specify different gamma value for each color channel
-g rg:gg:bg:rw:gw:bw: Specify also white balance (0.55:0.55:0.55:1.0:1.0:1.0)
-g + Enable software lookup-table
-e + Same as '-g +'
-g - Disable software lookup-table
-e - Same as '-g -'
-g '?' Display software lookup-table status and contents
-e '?' Same as '-g '?''
-e filename.ppm: Generate static equalization based on image in given raw PNM/PPM file.

Module parameters are modified and queried using the following syntax:: parameter=value; parameter?
The values are integers or a list of symbolic names separated by commas. This is the list of possible parameters and its symbolic values:
debug user, camera, init, logic, errors, adaptation, controlurbs, bit: stream, interrupts, mutex, common, frame, all
