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.

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

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.
