Adjusting the White Balance/Black Balance
Adjusting the White Balance
Adjusting the white balance and black balance in the order of AWB (white balance
adjustment)>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
display 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.
¡The auto black balance (ABB) must always be re-adjusted when the MASTER GAIN value for
the LOW SETTING, MID SETTING or HIGH SETTING on the setting menu has been changed,
when the super gain setting has been changed using the SUPER GAIN button, and when the
GAMMA setting (ON/OFF) on setting menu FUNCTION 1/5 page has been switched.
¡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
brightness of these lights appears to be constant. Especially in areas where the power line fre-
quency is 50 Hz, the vertical synchronizing frequency (approx. 60 Hz) of the NTSC and the
frequency (50 Hz) of the lighting tend to interact. This gives rise to flicker and to a phenome-
non 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,
wherever 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.
1 Set the switches as shown in the figure.
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”.)
2 Select the FILTER knob setting in accordance with the lighting conditions.
¡See FILTER knob (page 15) in the Shooting (Recording)/Playback Function Section for
examples of FILTER knob settings. If the setting of the FILTER knob is changed, a mes-
sage 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”.)
GAIN: Normally, set to 0 dB. When it is too dark,
it is set to the appropriate gain.
MENU SET/OFF: OFF
WHITE BAL: A or B
