2.4 Calibration with User White Pixel Correction Function
This camera is set to the optimal pixel correction with a daylight fluorescent lamp
(NEC FL20SD) before shipping.
Light sources and lens shading can cause non-uniformity.
Calibrate the camera with a user white pixel correction function to cope with lens
shading and non-uniform illumination by following below steps.
1) Set the lens and light source which you want to use.
2) Set NED_FFCMode to "Factory White".
3) Adjust the exposure time and gain to set the signal level to about 200 DN.
4) Execute NED_PRNUCalibration.
5) Change NED_FFCMode to "User White".
This calibration can improve the white balance and the waveform flatness of
the camera signal.
See below for more details.

4.8 Pixel Correction
The waveforms at the calibration processing are shown as an example of
this explanation when you use 3-wavelength fluorescent lamp with this camera.
(1) Waveforms using daylight fluorescent lamp
The waveform using daylight fluorescent lamp NEC FL20SD with
this camera is flat after adjusting white balance at Factory.
(2) Waveforms using 3-wavelength fluorescent lamp
The waveforms using 3-wavelength fluorescent lamp with this camera
at Factory white mode are shown below.
The white balance is broken.
