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.
The illustration above shows the range
over which the auto white balance
functions.
1) The effective range of automatic
white balance adjustment on this unit
2) Blue sky
3) Cloudy sky (rain)
4) TV screen
5) Sunlight
6) White fluorescent lamp
7) Halogen light bulb
8) Incandescent light bulb
9) Sunrise or sunset
10) Candlelight
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 auto 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 recognizing which is the
white colour under sunlight and which is
the white colour under a 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.
