7.17.4 LF_FF_ManualSetSelector
| RW | B |
0 to 49,
Increment: 1
Select the active Flat Field correction set. The last 18 sets that where
loaded will be stored in a cache memory. Sets that are present in cache
memory can be loaded as active set in between two subsequent frames.
For timing details see Figure 7-14. This feature is only available for
LF_FFSetSelectionMode = Manual
NOTE:
Rapid switching of sets without additional delay requires the selected sets to be present in cache. This
can be accomplished
before
image acquisition by sequentially selecting the sets to be used, or by programming
a sequence containing the sets to be used.
7.17.5 LF_FF_CalibrationROI
| RW | B |
UserROI
The FF calibration is performed on the user ROI.
SensorROI
The FF calibration is performed on the full sensor.
Figure 7-14: Timing diagram for the FFC function. If the command to change the correction set arrives in the
green timeframes it will be applied to the next frame.
7.17.6 LF_FF_Calibrate
| WO | B |
Command
Execute the FF calibration. A successful result is stored in the set indicated
by LF_FF_ManualSetSelector. This feature is only available for
LF_FFSetSelectionMode = Manual.
7.17.7 LF_FF_ResetCurrentSet
| WO | B |
Command
The current selected set is being reset. The gain is set to 1 for the whole
image. The set can thus be used as if the FFC function is off. This feature is

Note:
- Timing is only valid for preloaded
sets and for a sequence reset
- Preloading a set takes +-170ms
When the CXP command is received by the camera within this time
frame, the next frame will be corrected with the selected set.
When the CXP command is received by the camera within thIs time frame, it
can not be guaranteed that the correction will be applied on the next frame.
