Defect Pixel Correction
To enable Defect Pixel Correction, set the
DPC Enable
to
On
(default setting).
By means of
Factory/Customer Map Select
the selection of the active map can be
influenced. When it’s on
Auto,
Customer maps have priority if available else the
Factory maps will be used.
DPC Processing
will show
Active
when a valid DPC map is
in use.
Flat Field Correction
To enable Flat Field Correction, set the
FFC Enable
to
On
and the
FFC Mode
to
Normal
(default setting).
By means of
Factory/Customer Map Select
and
Map Select,
the selection of the active
reference maps can be influenced. When both are on
Auto
, the 1
st
dark and gain map
in the row which fits to the resolution and full well capacity setting will be selected.
Customer maps have priority over Factory maps. When
Factory/Customer Map Select
is
set to
Factory
or
Customer,
the selection will limited to those categories.
When
Map Select
is set to
Manual,
the active FFC Gain and FFC Dark map can be
selected from a list of maps. Factory maps are stored in a fixed order. Customer maps
can be organized to the user’s preference. As
an example, it is possible to store one
customer gain map per Full Well setting (HFW/LFW) and per Binning mode (1x1,
2x1) in combination with one customer dark map per Full Well setting (HFW/LFW)
and per Binning mode (1x1, 2x1). Binning 2x2 binning uses the same maps as binning
mode 2x1.
FFC Gain Map Status
and
FFC Dark Map Status
indicate if a valid map has been
selected.
FFC Processing
will show
Active
when both a valid FFC Dark and FFC Gain map is in
use.
The dark reference map can be updated using actual dark images from the detector,
for example when capturing images with long integration time. To do so, set the
FFC
Mode
to
New Dark
and perform an image
Snap
. The detector will output the requested
image to the host application. In detector volatile memory, the captured image will be
added to the current dark reference map using the
FFC New Dark Weight
value. The
dark referen
ce map stored in the detector’s non
-volatile memory, which is loaded on
power-up, is not automatically updated.
