CPA: Calibrate Flatfield
Display
Name
Calibrate Flatfield
Mnemonic
CPA
Argument(s) Algorithm
0.
Basic
1.
Low-pass Filter
# of lines to average
•
2048
•
4096
Target
0 to 4095 DN in 12 bit mode
0 to 255 DN in 8 bit mode
Description
Calibrate user PRNU flat field coefficients
Notes
•
Perform flat field calibration using the average of <# lines>.
•
With filter algorithm this average line is then smoothed and outlier
pixels are interpolated. Use this feature if your white reference is not
featureless.
•
Adjust pixel gain such that output will be <target>.
•
The target is first divided by horizontal binning factor and gain and
then the offset is subtracted. Therefore the output will go to the
target.
•
Because the PRNU can be less than 1, the target may be below the
current maximum value.
•
Coefficients are saved and loaded with user set (e.g. USS / USL)
•
The cpa command takes several seconds to complete. The slower the
line rate, the longer it will take.
DEK: Disable Esc Key
Display
Name
Disable Esc Key
Mnemonic
DEK
Argument(s) Mode
0.
Esc key is enabled
1.
Esc key is disabled
Description
Allow the use of the Esc key to be disabled so that upon boot-up the camera
will directly enter the ASCII command mode. With the Esc key disabled the
GENCP cannot be accessed.
Notes
To access the GenCP, you have to first issue the DEK 0 command in order to
enable the ESC key. Then reboot the camera.
