4. Begin Off Line (BOL-Module)
It is controlled by the Pipeline control. At the end
of an exposure line, the 4 highest order Bits of
the red pixel bus are separated from the DAC by
the module-internal logic and replaced by the
4 Bit register data and a clock is generated for
the red DAC. This results in an analogue voltage
selectable in 16 steps by the Software and used
to trigger the red laser so that a BOL pulse can
be generated. Apart from this, the initialisation
prerequisites for the triggering of the red laser
diode (Laser off BOL register = 0h, Dark
active) as well as the laser enable/disable control
are materialised in this module after the supply
voltage has been applied.
5. Facet correction
The facet correction is used to compensate minor
colour-dependent differences (
