Scanner Calibration
The following calibration procedures are performed
automatically when required. It is not necessary
that a technician or the operator intervenes.
The Scanner contains several optical elements
which are calibrated automatically.
− Replacement of the light sensors in the lamphouse:
The film drive software automatically finds the
exact positions of the 3 light sensors in the
lamphouse and the light sensor of the KG segments
when the corresponding routines are
called up. The positions are stored internally in
an EEPROM.
− White balance:
Red, green, blue scan without a film to check
the balance.
Brightness changes, above all of the lamp
brightness, are compensated.
− CCD pixel correction
