Automatic white balance
White balance adjustment recognises
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 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
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 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 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 recognise the reference
colour white.
Auto focus
The lens is moved forward or backward
automatically to bring the subject into
focus.
Auto focus has the following
characteristics.
≥ Adjusts the focus so that the vertical
lines of a subject are seen more
clearly.
