5-1. The purpose and principal of color
temperature adjustment
(1) Purpose: to reduce the difference in color temperature
among modules
(2) Principal: A module is in full dynamic range when RGB
Gain on OSD is 192. To adjust the white balance without
causing full dynamic range and full data, fix one of RGB
Gains at 192 and control the other two by reducing them
from 192.
