Automatic white balance
White balance adjustment recognizes the colour
of light and adjusts so the white colour will
become a pure white. The movie camera
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 movie
camera only stores white colour 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.

White balance
The image recorded by the movie camera 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
colour under different light sources. By recognizing
which is the white colour under sunlight and which is
the white colour under a fluorescent lamp, the movie
camera can adjust the balance among the other
colours.
Since white colour is the reference of all colours
(light), the movie camera can record pictures in a
natural hue if it can recognize the reference white
colour.

Auto focus
Auto focus automatically moves the focusing lens
forward and backward inside the movie camera 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 centre only.
Due to these characteristics, auto focus does not
work correctly in the following situations. Record
pictures in the manual focus mode.
