Adjusting the White Balance/Black Balance
Adjusting the White Balance
Adjusting the white balance and black balance in the order of AWB (white balance adjust-
ment) ABB (black balance adjustment AWB will provide a better picture.
Normally, the white balance and black balance do not need to be readjusted even if the power is
turned off and then on again.
However, the white balance must be readjusted when the lighting conditions change.
If black balance and white balance adjustments are started when the display mode is set to “2” or
“3”, messages informing of the adjustment course and results will appear on the viewfinder
screen. Set the display mode to “1” to not display these messages.
See “Display Mode and Setting Change Message” (page 57) for a description of setting the dis-
play mode.
<Notes>
The white balance and black balance cannot be adjusted while the setting menu appears on the
viewfinder screen. Therefore, be sure to set the MENU SET/OFF switch to OFF.
ABB must be executed again when the MASTER GAIN values on the LOW SETTING, MID SET-
TING and HIGH SETTING pages of the setting menu are changed, the S IRIS SW item is set to
+30 dB at the FUNCTION 2/5 page of the setting menu, or the GAMMA (ON/OFF) item is
switched at the FUNCTION 1/5 page of the setting menu.
With artificial lights, particularly with fluorescent lights and mercury-arc lamps, the strength of the
R, G and B colors changes in synchronization with the power line frequency even if the bright-
ness of these lights appears to be constant. Especially in areas where the power line frequency
is 50 Hz, the vertical synchronizing frequency (approx. 60 Hz) of the TV and the frequency
(50 Hz) of the lighting tend to interact. This gives rise to flicker and to a phenomenon where the
hue changes along with the passage of time, and it is it impossible to obtain the proper white
balance.
These phenomena can be reduced by setting the shutter speed to 1/100. For this reason, wher-
ever the unit is used under fluorescent or mercury-arc lamps and at a frequency of 50 Hz, the
shutter speed must be set to 1/100 and the white balance obtained. This shutter speed of 1/100
should also be used during shooting.

Set the switches as shown in the figure.
MENU SET/OFF: OFF
WHITE BAL: A or B
FILTER knob
OUTPUT: CAM
GAIN: Set the smallest gain value possible.
If the settings of the GAIN and WHITE BAL switches are changed, a message informing of
the new setting will appear for about 3 seconds at the setting change message display posi-
tion on the viewfinder screen. (However, the message appears only when the display mode is
set to "3".)

Select the FILTER knob setting in accordance with the lighting conditions.
See FILTER knob (page 15) in the Shooting (Recording)/Playback Function Section for ex-
amples of FILTER knob settings. If the setting of the FILTER knob is changed, a message
informing of the new setting will appear for about 3 seconds at the setting change message
display position on the viewfinder screen. (However, the message appears only when the
display mode is set to “3”.)
