Used to switch the shutter mode.
STEP:
The shutter speed can be changed with the
[SPEED] item.
V. SCAN: The shutter speed can be changed with the
[SPEED] item.
Enables more detailed setting than [STEP].
RANDOM: Used to synchronize the CCD accumulation
timing with the Trigger input.
The shutter speed can be changed with the
[SPEED] item.
EEI: Used to automatically change the shutter
speed in accordance with the brightness of the
subject.
OFF: Fixed at 1/7.5 s.
The shutter speed can be changed when SHUTTER is
set to “STEP”, “V.SCAN” or “RANDOM”.

MEMO
• When the shutter speed is slower than 1/7.5 s, the
following phenomena may occur.
1) The screen update rate becomes longer in the case
of digital output.
2) The displayed image will appear intermittently in the
case of analog output.
3) Time will be required for the auto white, auto iris and
ALC operations.
If the shutter speed is set slower than 1 s, these
operations will behave as follows.
Auto white : Auto white balance function cannot be started.
( ੬ page E23 White balance adjustment)
Auto iris : Stops at the iris value at that time.
ALC : Stops at the sensitivity at that time.
To use a shutter speed slower than 1 s, use with the fol-
lowing settings selected:
IRIS MODE : MANUAL
GAIN
: STEP or V.GAIN
• There may be shortage of light when the shutter speed is
increased. In this case, adjust the iris or sensitivity. Atten-
tion should be paid to the picture quality when the sensi-
tivity is raised since the image becomes coarse.

Used to switch the sensitivity mode.
STEP:
The sensitivity can be changed with the “LEVEL”
item.
ALC: The sensitivity is automatically changed in ac-
cordance with ambient brightness.
V.GAIN: The sensitivity can be changed in detail with
the “LEVEL” item.
Sets the maximum sensitivity of ALC, which automatically
switches the sensitivity in accordance with ambient bright-
ness.
Sets the minimum value for the shutter speed when the
shutter mode is set to “EEI”.
1/7.5s: Set to 1/7.5s.
1s:
Set to 1s.
* When analog output is used, the monitor image will be
stopping many times when the shutter speed becomes
slower, so set at “1/75.s”.
