For a toy camera like this, it's most likely the raw output of the CCD
device and needs a fair amount of processing of the raw pixel data.  The
dc25 backend shows an example of this kind of processing.  (It's not likely
that you'll be able to use that kind - just an example of that type of

My guess is that the most effective technique would be to open up the camera
and try to identify the manufacturer of the CCD.  Then see if you can get
anything from them.  I think that's how the dc-25 algorithms were
originally developed (not by me!)
