backlight and filters - algorithms needed

[Peter Pregler]

Hi all,

I recently compared the output of our driver with the m$-stuff and found
the following obvious difference. There is a 'backlight' option and some
'filters (50/60Hz)' that one can switch on/off in the m$-video panel. The 
first one is usefull in dark scenes. In case of compressed mode the image
looks less grainy. The second one eliminates horizontal stripes that seem
to occur during exposure changes. Has anyone an idea what kind of image
processing filters those are?
