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/

Set the switches as illustrated below.

at [ABB], then release it.

black balance automatically adjusted.

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, move the cursor (
>
), then
press the JOG dial button. The menu option
DETECTION can be found in the <BLACK
SHADING> screen, which is accessible from the
MAINTENANCE page.
By turning on the SHD.ABB SW CTL in <SW
MODE> (page 178) and then continuously pressing
the ABB switch for 8 seconds or longer, black
shading can be automatically adjusted after the
Auto-Black-Balance operation. While the black
shading is being adjusted, ensure that the lens iris is
closed completely until the “B-SHD OK” message is
displayed in the viewfinder.
However, when the remote control unit (AJ-RC10G:
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.
