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.
Automatic adjustment
When using an AW-RP50, AW-RP120, or AK-HRP200
Refer to the operating instructions for the controller.
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 a waveform monitor for the adjustment.)
Adjust the black level in accordance with the units and devices used.
When using an AW-RP50, AW-RP120, or AK-HRP200
Refer to the operating instructions for the controller.
Genlock adjustment
The genlock adjustment is performed to achieve phase alignment by
applying external synchronization (genlock) when a multiple number of
cameras will be used or when the unit will be used in combination with
other devices.
This unit supports tri-level sync external synchronization signals.
Ask your dealer to perform this adjustment.
(Use a dual-trace oscilloscope for the adjustment.)
Horizontal phase adjustment
Observe the waveforms of the external sync signal input (tri-level sync
signal) and video signal output on the dual-trace oscilloscope, and use
the controller to bring the horizontal phase into alignment.
External sync signal
input
(tri-level sync signal)
Video signal output
Bring the horizontal
phase into alignment.
Example: When the tri-level sync phase is adjusted
These operations can be performed using the camera menus by
following the operation steps in “Basic setup operations” (→ pages 30
to 37).
<NOTE>
• The unit is not equipped with an output connector for analog video
signals.
Observe and adjust the analog output of an SDI waveform monitor,
or use the synchronous phase check function of the SDI waveform
monitor.
