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

accessory wireless remote control

The procedure is the same as with “Automatic adjustment” in “White balance adjustment” (page 31).

The auto white balance adjustment (AWC) and auto black balance adjustment (ABC) 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 doing the adjustment

using the controller

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.)
