Automatic white balance
White balance adjustment recognizes the
colour of light and adjusts so the white colour
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 colour
information under several light sources,
automatic white balance adjustment does not
function normally under other light sources.

Outside of the effective range of automatic
white balance adjustment, the image will
become reddish or bluish. Even within the
effective range of automatic white balance
adjustment, the automatic white balance
adjustment may not function properly if there is
more than one light source. For light outside
the functional automatic white balance
adjustment range, use the manual white
balance adjustment mode.
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

colour under different light sources. By
4)
recognizing which is the white colour under
sunlight and which is the white colour under a
5)
fluorescent light, the unit can adjust the
balance among the other colours.
Since the white colour is the reference for all
the colours (that make up light), the unit can
record pictures in a natural hue if it can
recognize the reference colour white.
