PRNU Calibration Results
Success
PRNU calibration was successful.
Greater_than_1_percent_clipped
Greater than 1 % of PRNU coefficients have been calculated to be greater than the maximum allowable 8
or less than 1 (which will happen if the target is less than the maximum pixel output).
Timeout
FPGA did not return end-of-line statistics or video line.
Setting Digital Offset
The digital offset is set to zero when you perform FPN correction (Enable FPN feature). If you are unable
to perform FPN correction, you can partially remove FPN by adjusting the digital offset.
Use the Digital Offset Selector to select the taps, and the Digital Offset (DN) parameter to choose the
subtracted offset value in a range from 0 to 2048.
Subtracting Background
Use the Background Subtract features after performing flat field correction if you want to improve your
image in a low contrast scene. It is useful for systems that process 8 bit data but want to take adv antage of
the camera’s 12 bit digital processing chain. You should try to make your darkest pixel in the scene equal
to zero.
Background Subtract Selector to select taps and Background Subtract (DN) to subtract a value in a
range from 0 to 4095 DN.
Setting Digital System Gain
Improve the signal output swing after a background subtract. When subtracting a digital value from the
digital video signal, using the Background Subtract DN feature, the output can no longer reach its
maximum.
Use this command to correct for this where:
Digital Gain (DN) =
max output value
max output value - Background Subtract value
Gain Selector: Tap selection. Digital Gain Raw: Gain setting. The gain ranges are 0 to 65535. The digital
video values are multiplied by this value where:
Digital Gain (DN) =
i
4096
Use this command in conjunction with the Background Subtract Raw command.
4k model limited to 12953 (0 dB effective at factory set analog gain of -10 dB).
