ªAutomatic white balance
White balance adjustment recognizes the color of
light and adjusts so the white color will become a
pure white. The Camcorder 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 Camcorder only stores white
color information under several light sources,
automatic white balance adjustment does not
function normally under the 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 auto white
balance adjustment range, use the manual white
balance adjustment mode.

ªWhite balance
The image recorded by the Camcorder may
become bluish or reddish under the influence of
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 lamp, the
Camcorder can adjust the balance among the
other colors.
Since white is the reference of all colors (light),
the Camcorder can record pictures in a natural
hue if it can recognize the reference white color.
ªAuto focus
Auto focus automatically moves the focusing lens
forward and backward inside the Camcorder to
bring the subject into focus.
Auto focus has the following characteristics.
≥Adjusts so that the vertical lines of a subject are
seen more clearly.
≥Attempts to bring an object with higher contrast
into focus.
≥Focuses on the screen center only.
Due to these characteristics, auto focus does not
work correctly in the following situations. Record
pictures in the manual focus mode.
Recording a subject with one end located
closer to the Camcorder and the other end
farther away from it
≥As auto focus adjusts at the center of an
image, it may be impossible to focus on a
subject that is located in both the foreground
and background.
Recording a subject behind dirty or dusty glass
≥
The subject behind the glass will not be focused
because the focus is on the dirty glass.
Recording a subject that is surrounded by
objects with glossy surfaces or by highly
reflective objects
≥The recording subject may become blurry
because the Camcorder focuses on the
objects with glossy surfaces or on highly
reflective objects.
Recording a subject in dark surroundings
≥The Camcorder cannot focus correctly
because the light information that comes
through the lens decreases considerably.
Recording a fast-moving subject
≥As the focus lens-inside moves mechanically,
it cannot keep up with a fast-moving subject.
Recording a subject with little contrast
≥A subject with little contrast, such as a white
wall, may become blurry because the
Camcorder achieves focus based upon the
vertical lines of an image.
