Adjustments and Settings for Recording : Adjusting the White balance and Black Balance
The black balance must be adjusted when:
z You use your unit the first time;
z Your unit has not been used for some time;
z The ambient temperature has changed substantially;
z The gain switchover value has been changed; or
z S.GAIN (super gain) has been set with the USER MAIN/
USER1/USER2 button.
z When you are changing the assignment for DS.GAIN on
the USER SW GAIN screen of the menu
1 Set the switches as illustrated below.
2 Tilt the AUTO W/B BAL switch so that it is
positioned at [ABB], then release it.
z The switch returns to the central position with the
black balance automatically adjusted.
z During adjustment, the viewfinder displays the
following message:
Note
During adjustment, the lens iris automatically becomes
CLOSE.
z The adjustment will take effect in a few seconds and
the following message will appear:
The adjusted value is automatically stored in the
memory.
Notes
z Ensure that the lens connector is connected and the
lens iris is CLOSE.
z During a black balance adjustment, light is
automatically cut off.
z During a black balance adjustment, the gain switchover
circuit is automatically switched.
The viewfinder screen may flicker and/or display noise;
this is not a failure.
z If you find the black shading annoying after performing
an auto black balance adjustment, adjust the black
shading. To do so, go to the menu option DETECTION
(DIG), move the cursor (>), then press the JOG dial
button. The menu item DETECTION (DIG) is found in the
<BLACK SHADING> screen on the MAINTENANCE
page.
When you set the SHD.ABB SW CTL menu option to
“ON” and press the AUTO W/B BAL switch for 8
seconds or longer, [B-SHD READY] is displayed in the
viewfinder and black shading can be automatically
adjusted after the automatic black balance operation.
While the black shading is being adjusted, the “B-SHD
ACTIVE” message is displayed in the viewfinder.
Ensure that the lens iris is closed completely until the
“B-SHD OK” message is displayed in the viewfinder.
The menu item SHD. ABB SW CTL is found in the <SW
MODE> screen on the CAM OPERATION page.
However, when the remote control unit (AJ-RC10G:
optional accessory) or extension control unit (AG-
EC4G: optional accessory) is connected, automatic
black shading cannot be executed even if the ABB
switch is held down.
z To cancel the automatic black balance adjustment in
process (the viewfinder displays “ABB ACTIVE”), flip
the AUTO W/B BAL switch down to [ABB] again.
If automatic adjustment is cancelled, the value in effect
before automatic adjustment will be used.
Each value in memory is retained even if the camera-
recorder is turned off.
