GAIN
Adjusts the video gain.
Selection Function
STEP Sets the video gain to the desired level. Use this
setting for shooting in an extremely dark place
where even fully opening the lens iris still does not
produce an acceptably bright image. The gain level
can be set in the range from 0 to 24 dB in units of 1
dB.
AGC Automatic gain control. Automatically adjusts the
gain according to the brightness of the object to be
shot. This setting is useful for shooting when lighting
conditions may change.
You can select the maximum gain level to be
adjusted to 6, 12, 18 or 24 dB with the LIMIT setting.
HYPER Increases the video gain to about 30 dB. This
setting is useful when the lighting condition is very
dark.
SHUTTER (electronic shutter)
Selects the electronic shutter modes.
This function enables you to obtain blur-free images of fast-
moving objects and acceptably bright still images of objects
shot in poor lighting conditions.
Selection Function
Use for fine adjustment of the video output level in
VARIABLE
long exposure mode (low-speed mode) or in clear
scan mode (high-speed mode).
Long exposure mode
You can set the SPEED value in units of 1 frame.
For example, if you set to 50 frames (about 1.7
seconds), the video signal produced during this set
time is output in the form of one complete frame at
B
intervals of about 1.7 seconds. These pictures,
which contain 50 frames of video information, are
much brighter than normal one-frame images. This
mode is useful for shooting a poorly illuminated
object in a dark place.
To set the shutter speed
1 Display OFF by pressing the
B
simultaneously.
2 Select the SPEED value by pressing the
button. Each time you press the button, the value
changes in units of 1 frame.
To convert the value into the shutter speed
Example: When the value is set to 5 frames
5 1/30 = 0.1666 seconds (DXC-390)
5 1/25 = 0.2000 seconds (DXC-390P)
Notes
• Do not use AGC, CCD-IRIS, ATW, DCC+ and
DYNALATITUDE functions in long exposure
mode.
• When you set the shutter speed to 1 second or
higher, set the gain level to 0 dB.
