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

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 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.

Auto focus has the following 
characteristics.
≥ Adjusts the focus so that the vertical 

lines of a subject are seen more 
clearly.
