I'd call the file "output_norm".

Not sure about this one, I think I'd simply call it "colorbars".

This is "colordepth".

> 4. change_resolution[1-2] : 1 for the width(x) and 2 for the height(y)

I would say "output_width" and "output_height".

"half_resolution" ?

Using "format" is a bit confusing IMHO. What about "output_source"? (Oh
well this is maybe even more confusing...)

As a general rule, you don't want to prepend the action to the file

Well, without the hardware I probably won't help much - and I don't
really plan to read the full data sheet ;) Don't know what to do with
these. If it's not a "public" think, we don't care much, except that it
might conflict with something else someday... Do as you want. If it's
not widely used, this also mean we can change it later if needed.
