10.3.5 Gain Control

The IVS can change the brightness of the video image

electronically. This gain control can be automatic or manual.

If the automatic control is selected, the IVS outputs the best

possible image brightness at all the time. Light changes in

front of the film camera are compensated by the IVS; the

brightness impression remains almost unchanged.

Gain control can be adjusted in two different ways.

It is possible to control it using the keyboard on the IVS or

using the on-screen control menu.

Using the Keyboard

Check all settings on the connected monitor.

• By pressing the WB key Ï the setting alters between

manual and automatic control. An illuminated LED shows

the setting manual gain control (MGC)

photo

.

• If manual gain control is selected (LED is on), the

brightness of the video image can be manually altered.

By using the Ê or Ë key brightness can be increased

or decreased. An automatic compensation of different

light levels in front of the camera is suppressed.
