[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.

[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 71.
● 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).
See "GAIN BOOST UNDER LOLUX CONDITION" on
page 86.

[GAIN] Sensitivity selector switch
Electronically boosts the light sensitivity when there is
insufficient illumination on the subject. The boosting level
differs depending on the switch position as follows:
(Factory presets)
L : 0 dB (no boosting is applied)
M : 9 dB (boosted to approximately 3 times the original)
H : 18 dB (boosted to approximately 8 times the original)
● The boosting level for each switch position can be
changed with the CAMERA OPERATION MENU screen.
See page 71.
The more the boosting level is increased, the more the
resulting image will be noisy.

[OUTPUT] Color bar/Camera/Auto knee switch
This switch is used to select the output signal. When the
video signal from the shooting camera is selected, the auto
knee function is available.
CAM. AUTO KNEE ON: Outputs the video signal from the
shooting camera. In this mode, the auto knee function is
available.
CAM. AUTO KNEE OFF: Outputs the video signal from
the shooting camera. In this mode, the auto knee function
is not available.
BARS: Outputs the colour bar signal. In this mode, the auto
knee function is not available. Set to this position when
adjusting the video monitor or when recording the colour
bar signal. Color bars will not appear when Full Auto is set
to ON or when in the VTR mode.
AUTO KNEE function
When shooting a foreground subject, such as a person,
etc., with a high-brightness background, if the brightness
level is set for the foreground subject, the background image
will be blurred with white. In such a case, a clearer
background is obtained when the auto knee function is used.
It is effective especially in the following cases:
● When shooting a person indoors with a view to the
landscape out through a window.
● When shooting a person in the shade on a fine day.
● When shooting a high-contrast scene.
CAUTION:
If a fast moving high-brightness section like a car in
sunlight is shot, the auto knee function may change
the brightness of the entire image along with the motion
of the object. In this case, set the auto knee function to
OFF.
