WBC MODE (White Balance Control)
5.5.1.6
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
following table shows the color temperature of some light sources for reference. The default setting
is
AUTO.
