Description
Sets the enable state of the fixed
pattern noise (FPN) compensation.
Off Disables FPN compensation.
Applies the FPN compensation to
Active
the image.
Selects the shutter target.
The shutter is an external shutter
External
outside the camera body.
Internal Internal camera mechanical shutter.
FPN calibration will use the internal
mechanical shutter, but with
advanced modelization which
provides more uniform images.
This option may not be available for
cameras that were shipped prior to
release 2.41.
Calibrates the FPN compensation
coefficients. Ideally the camera
should be at normal operating
temperature. If shutterTarget is set
to External, a scene with uniform
temperature and reflectivity should
be presented to the camera to
properly calibrate the FPN
compensation. Click "Press" to
calibrate.
Reports the status of the last FPN
calibration.
FPN calibration has not been
NotCalibrated
calibrated yet.
FPN calibration has been loaded
from flash memory at boot.
InProgress FPN calibration is in progress.
Error FPN calibration has failed (cause
unknown)
Timeout FPN calibration has failed because
not enough frames were acquired
within a 5 second window. When
acquiring in external triggered
mode, trigger pulses should be
provided to the camera during FPN
calibration.
Success FPN calibration has completed
successfully.
FPN calibration ran successfully but
the internal shutter had to be
retriggered in order to close it
completely.
Camera detected that the internal
shutter did not close completely
prior to FPN calibration.
