Pictures taken with the driver:

Mr Pingus, but this time I did really basic "interpolation" to have a 352x288 picture:
As you can see, the colors are somewhat strange. It is probably due to the bad luminosity in my room (except for the first one, it was an error in the green gain register ). You can also see the dead pixels on the sensor.
Update !! (04/13/2004)Until now, the webcam was capturing pictures at a very slow framerate (about 1.5 fps). I managed to get it work at 8fps (yeepee!!) by tweaking the registers of the cmos sensor. It is now nearly usable. The problem is now that the brightness of the picture is very low, and i didn't find a way to get it back to normal. I'll work on it next days. I will then just need to do some cleaning of the code, check if it works against a 2.6.5 kernel (shouldn't be a problem) and release the driver to the impatient world.
The dark picture..The picture is also interlaced, I'm working on an apropriate filter to get a "real" 352x288 picture
Update !! (04/21/2004)Finally managed to get some time to clean up the code and create a patch..So here it is !
Update !! (05/13/2004)I joined the sonix sourceforge team on their effort to support sonix based webcam. So now, the code can be found on the CVS.
By the way, I fixed the interpolation algorithm and a bug in the data parser. The pictures are now brighter:
The driver
The driver is here. It is a patch against the linux 2.6.4 kernel. It is released under the GPL (blah blah ...no warranty...). It uses the usbvideo module.
You should check the Sonix project CVS page.
