Chapter 4 Adjustments and settings for recording

4-1-2 Adjusting the black balance

The black balance needs to be adjusted in the following cases:

When the unit is used for the first time

When the unit is used after it has not been used for a prolonged period of time

When the unit is used in an ambient temperature which has fluctuated significantly

When the value selected for the gain switch has been changed

When the super gain setting has been performed using the USER MAIN, USER1 or USER2 button

When the gamma ON/OFF setting has been changed

1 Set the switches as shown in the figure.

AUTO W/B BAL switch:

OUTPUT: CAM

Use this to execute ABB.

 

2 Set the AUTO W/B BAL switch to the ABB position, and then release it.

The switch returns to the center, and the adjustment is performed.

3 While the adjustment is in progress, the following message appears on the viewfinder screen.

ABB ACTIVE

<Note>

While the adjustment is in progress, the lens aperture is automatically set to CLOSE.

4 Adjustment is completed in several seconds. (A message similar to the one shown in the figure below now appears.) The adjustment value is automatically saved in the memory.

ABB OK

<Notes>

Check that the lens connector has been connected and that the lens aperture is set to CLOSE.

While the black balance is being adjusted, the aperture is automatically set to the light-shielding status.

While the black balance is being adjusted, the gain selector circuit is switched automatically.

Flicker or noise may appear on the viewfinder screen, but this is not indicative of malfunctioning.

If the black shading is still unsatisfactory although the “ABB OK” message is displayed, perform menu operations to open the <BLACK SHADING> screen

from the MAINTENANCE page, move the arrow mark (>) to the DETECTION item, press the JOG dial button, and proceed with the black shading adjustment. If the ABB switch is held down for 5 or more seconds, the black shading can be automatically adjusted after the ABB operation. (See the SHD.ABB SW CTL item under “7-5-5 SW MODE.”)

If the AUTO W/B BAL switch is pushed down to the ABB position again while the black balance is being automatically adjusted (ABB ACTIVE), the adjustment will be aborted.

The adjusted value in this case is the value before automatic adjustment was performed.

Black balance memory

The values stored in the memory are retained even after the unit’s power has been turned off.
