Automatic white balance
White balance adjustment recognizes the color
of light and adjusts so the white color will
become a purer white. The unit determines the
hue of light that comes through the lens and
white balance sensor, thereby judging the
recording condition, and selects the closest hue
setting.
This is called automatic white balance
adjustment.
However, since the unit only stores white color
information under several light sources,
automatic white balance adjustment does not
function normally under other light sources.

White balance
The images recorded by the unit may become
bluish or reddish under the influence of certain
light sources. To avoid such phenomena, adjust
the white balance.
White balance adjustment determines the white
color under different light sources. By
recognizing which is the white color under
sunlight and which is the white color under a
fluorescent light, the unit can adjust the
balance among the other colors.
Since the white color is the reference for all the
colors (that make up light), the unit can record
pictures in a natural hue if it can recognize the
reference color white.
