HOW TO COMPILE THE DRIVER:
You need to compile the driver only if you are a developer
This is a driver for the OV511, a USB-only chip used in many "webcam" devices.
Any camera using the OV511/OV511+ and the OV6620/OV7610/20/20AE should work.

+Video capture devices that use the Philips SAA7111A decoder also work. It
supports streaming and capture of color or monochrome video via the Video4Linux
API. Most V4L apps are compatible with it. Most resolutions with a width and
height that are a multiple of 8 are supported.
chmod 666 /dev/video
chmod 666 /dev/video0 (if necessary)

Now you are ready to run a video app! Both vidcat and xawtv work well for me
at 640x480.

[Using vidcat:]
vidcat -s 640x480 -p c > test.jpg

[Using xawtv:]
From the main xawtv directory:
make
make install
-Now you should be able to run xawtv. Right click for the options dialog.

The algorithm purely describes the conversion from compressed Bayer code used
in the SN9C10x chips to uncompressed Bayer. Additional steps are required to
convert this to a color image (i.e. a color interpolation algorithm).
