Adjusting the white balance and black balance

Adjusting the black balance

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

O When the unit is used for the first time

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

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

O When the value selected for the gain switch has been changed

O When the super gain setting has been performed using the USER button

O When the gamma ON/OFF setting has been changed

1 Set the switches as shown in the figure.

OUTPUT: CAM

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.

AUTO W/B switch

3 While the adjustment is in progress, the following message appears on the viewfinder screen (but only when “2” or “3” has been set as the display mode).

<Note>

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

ABB ACTIVE

Message appearing while the adjustment is in progress

4 Adjustment is completed in several seconds. (A message similar to the one shown in the figure now appears.)

The adjustment value is automatically saved in the memory.

ABB OK

Message appearing upon completion of the adjustment

<Notes>

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

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

O 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.

O If black shading is not satisfactory even with ABB OK, open the BLACK SHADING screen of CAM MAIN MENU 4, and adjust the black shading. (Refer to page 91.)

O When the super gain has been set to ON, the black balance is executed at the preset position in the white balance memory.

O When the AUTO W/B BAL switch is pressed again to the ABB side when the black balance is being adjusted automatically (ABB ACTIVE), the adjustment operation will stop.

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