Black balance adjustment
Adjust the zero levels of the three primary colors (RGB) to reproduce
black accurately. If the black balance is out of adjustment, not only will
black be reproduced poorly, but the color tones of the screen as a whole
will also be degraded.
Readjustment of the black balance is not required under normal
circumstances but is necessary in the following situations.
• Perform adjustment when using the unit for the first time or when
the unit has not been used for a prolonged period.
• Perform adjustment when the ambient temperature changes
significantly, such as during changes of the season.
<NOTE>
• After adjusting the black balance, and [SERIAL] or [IP] of [TRACKING
DATA OUTPUT] is set to [ON], the tracking data output may be
delayed or the value may not be updated. (→ page 71)
Black level (master pedestal) adjustment
The black level can be adjusted when using a multiple number of
cameras including the unit. Ask your dealer to perform this adjustment.
(Use an oscilloscope or waveform monitor for the adjustment.)
Adjust the black level in accordance with the units and devices used.
When performing operations from a wireless
remote control

Adjust the value in [PAINT] – [PEDESTAL] –

Automatic adjustment
When performing operations from a wireless
remote control
In Step 3 for "Automatic adjustment" (→ page 44) of "White
balance adjustment", when you press and hold the <SET> button for
approximately 2 seconds, auto black balance adjustment (ABB) is
executed and the black balance is set.
When this takes place, the lens is closed and then the adjustment is
performed so the screen will temporarily turn black.
• When the black balance adjustment is completed successfully, the
"ABB OK" message appears at the center of the screen.
<NOTE>
• Adjustment cannot be performed while the color bar is displayed.
Switch to the camera image by pressing the <MODE> button.
• The black balance cannot be adjusted during preset playback.
