Black balance adjustment
Black balance adjustment
In order for the black to be reproduced accurately, the zero
levels of the three primary colors (RGB) are adjusted. If the
black balance has shifted out of adjustment, not only will the
black be reproduced poorly but the color tones of the entire
screen will also be degraded.
Normally, the black balance need not be re-adjusted, but it is
necessary in the following situations.
This adjustment must be performed when using the
unit for the first time or when the unit has not been
used for a prolonged period.
The adjustment must be performed when the ambient
temperature has changed significantly and at the
change of the seasons.
Automatic adjustment
When performing the operations
using the wireless remote control
The procedure is the same as with “Automatic adjustment” in
“White balance adjustment” (page 22).
The auto white balance adjustment (AWB) and auto black
balance adjustment (ABB) can be performed, and the black
balance setting entered.
The white balance setting is also entered at the same
time so ensure that the conditions for adjusting the white
balance are met before proceeding.
The black balance cannot be adjusted when color bars
are displayed. Press the [MODE] button to switch to the
camera picture.
When performing the operations using the controller
When the AW-RP655 or AW-RP555 is connected:
1 Press the [ABC] button.
The auto black balance operation is executed, and the
black balance setting is entered.
The [ABC] button’s lamp or LED blinks while the black
balance is being adjusted, and its lamp goes off when
the adjustment is completed successfully. It lights if the
black balance could not be adjusted.
If color bars have been selected (the [MODE] button
or [BAR/CAM] button lights), it means that the [ABC]
button is not working or that the auto black balance
adjustment has failed. (The button’s lamp lights.)
When the AW-RP50 is connected:
Refer to the Operating Instructions of the controller.
