Calibration means "white calibration". In the moment I don't know
exactly what can be done with it. The scanner scans a white area
and sends the data to the driver. The driver can do something
with the data and sends back one line. In the moment I sent back
the last line of the scanned white area, that works fine.
It looks like a white calibration table for each pixel of the ccd that
is used for the requested scan. So - I think - if a CCD-pixel has an other
output level than the other CCD-pixels, it can be corrected that way.
May be it is possible to do a kind of highlight-function by that.
