6 [FULL AUTO] Full auto shooting ON/OFF button
and indicator

off.

(ALC) to automatically adjust the video signal level and
the white balance to their optimum levels.
The audio recording level will operate in the auto
adjustment mode.
● The iris is placed in automatic mode even if the iris mode
switch of the lens is in manual.
● The gain will vary continuously to the maximum of +18
dB. The shutter speed will vary continuously to the
minimum of 1/240 of a second.

7 [BLACK] Black stretch/black compression switch
Switches the gain for the dark section of the image.
Set to an appropriate position depending on the video signal
to be shot.
STRETCH : By stretching the signal only for the dark
section, contrast in the dark sections of the
image is enhanced.
NORMAL : Standard mode.
COMPRESS : When an entire image is relatively light and
the contrast is low, the gain of the dark
sections is compressed to increase the
contrast.
8 [LOLUX] LOLUX On/Off button
This button toggles the LOLUX mode on and off.
● LOLUX gain gives extremely low light level sensitivity for
special applications. This will result in an increase of 30
dB in the LOLUX mode.
● The gain up value can be selected from the menu.
☞ See page 75.
● LOLUX operation takes priority over normal gain setting.
● If the unit is placed in the LOLUX mode when it is in full
auto shooting mode, the auto level control (ALC) (one of
the full auto shooting functions) will be made inactive, so
that the LOLUX mode is given preference (FAW still
remains active).
