framerate This setting controls frame rate of the camera. This is
an approximate setting (in terms of "worst" ... "best")
because camera changes frame rate depending on amount
of light available. Setting 0 is slowest, 6 is fastest.
Beware - fast settings are very demanding and may not
work well with all video sizes. Be conservative.

hue_correction This highly optional setting allows to adjust the
hue of the image in a way slightly different from
what usual "hue" control does. Both controls affect
YUV colorspace: regular "hue" control adjusts only
U component, and this "hue_correction" option similarly
adjusts only V component. However usually it is enough
to tweak only U or V to compensate for colored light or
color temperature; this option simply allows more
complicated correction when and if it is necessary.

init_brightness These settings specify _initial_ values which will be
init_contrast used to set up the camera. If your V4L application has
init_color its own controls to adjust the picture then these
init_hue controls will be used too. These options allow you to
preconfigure the camera when it gets connected, before
any V4L application connects to it. Good for webcams.

The 352x288 is the native size of the Model 1 sensor
array, so it's the best resolution the camera can
yield. The best resolution of Model 2 is 176x144, and
larger images are produced by stretching the bitmap.
Model 3 has sensor with 640x480 grid, and it works too,
but the frame rate will be exceptionally low (1-2 FPS);
it may be still OK for some applications, like security.

10 = YUV420 12 bpp - Original video, compression enabled
13 = YUV422P 16 bpp - Original video, compression enabled
15 = YUV420P 12 bpp - Original video, compression enabled
8 = YUVY 16 bpp - Software conversion from UYVY
7 = YUV422 16 bpp - Software conversion from UYVY
1 = GREY 8 bpp - Software conversion from UYVY
6 = RGB555 16 bpp - Software conversion from UYVY
3 = RGB565 16 bpp - Software conversion from UYVY
4 = RGB24 24 bpp - Software conversion from UYVY
5 = RGB32 32 bpp - Software conversion from UYVY
When not 0, this parameter will override 'decompression'.
Default: 0 for every device. Initial palette is 9 (UYVY).
Note: If 'w9968cf-vpp' is not present, this parameter is set to 9.
