4.2.11 White Pixel Correction Data Save
Save the user arbitrary white pixel correction data of analog gain in flash memory.
The data at each step of analog gain can be saved.

In a simple average mode, set camera output at about 200DN and send
commands of wht, shc2 200 for pixel correction.
The data of camera outputs is corrected at the 200DN and vicinity.
Note
：
When the output signal setting2 is set in simple addition mode (vod2),
the second parameter (calibration level) of the pixel correction should be set
as follows.
In case of voa x 0 and voa x 3, the second parameter (calibration level) of the
pixel correction should be set at 100DN which is in half of digital number,
because the data is increased approximately two times by the data in simple
average mode.
In case of voa x 2, the second parameter (calibration level) of the pixel
correction should be set at 50DN which is in quarter of digital number,
because the data is increased approximately four times by the data in simple
average mode.
The data of camera outputs is corrected at the 200DN and vicinity.
The explanation is mentioned above in case of 8 bit output but the explanation
in case of 10 bit output is the same because the second parameter (calibration
level) of the pixel correction in 10 bit output is entered with 8bit output
conversion value.
