“Component”. Choosing the first item “Auto Calibration” in factory mode will reach this basic requirement. The
detail calibration method is shown at section 1.4.1. After signal calibration, we can go to next step, color
temperature alignment. The default calibration values are as below

Below are basic concepts of adjusting RGB gain/offset that can meet spec requirement. When tuning white
balance (color temperature), we manually adjust R, G and B gain and offset by following below rules to satisfy
spec requirement.
