7.5.2 White Balance

Shown below is the drop-down menu for controlling the camera's White Balance (color balance).
A camera needs to find a reference color temperature as a way of measuring the quality of a light
source for calculating all other colors. The unit for measuring this ratio is in Kelvin (K) degrees. Users
can select one of the White Balance Control modes according to the operating environment. The table
below shows the color temperature of some light sources for reference.
Light Sources
Cloudy Sky
Noon Sun and Clear Sky
Household Lighting
75-watt Bulb
Candle Flame
Three White Balance modes are available:

Auto – The Auto Balance White mode computes the white balance value output using color
information from the entire screen. It is suitable for an environment with a light source color
temperature in the range of approximately 2,700 ~ 7,500K.

ATW (Auto Tracking White Balance) – The Auto Tracking White Balance function automatically
adjusts the white balance in a scene while temperature color is changing. The ATW Mode is
suitable for an environment with a light source color temperature in the range of
approximately 2500 ~ 10,000K.
