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 certain 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
Others
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 ifthere
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 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.
Auto focus
The lens
is
moved forward or backward
automatically to bring the subject into
focus.

characteristics.
• Adjusts the focus so that the vertical
