V. SCAN: The shutter speed can be changed with the
[Speed] item.
Enables more detailed setting than [STEP].
EEI:
Used to automatically change the shutter speed
in accordance with the brightness of the subject
.
OFF: Fixed at 1/7.5 s.
RANDOM: Used to synchronize the CCD accumulation
timing with the Trigger input.
The shutter speed can be changed with the
[Speed] item.
The shutter speed can be changed when Shutter is set to
“STEP”, “V.SCAN” or “RANDOM”.
When the accumulation time exceeds 2 seconds in the V.
SCAN mode, click to reset the CCD integration.
This button is only valid when V. SCAN is selected on the
Shutter screen and the Speed item is set to 2s or slower.

MEMO
• When the shutter speed is slower than 1/7.5 s, the follow-
ing phenomena may occur.
• Time will be required for the auto white, auto iris and
ALC operations.
If the shutter speed is set to 2 sec or longer, these op-
erations will behave as follows. (However, 1.000 sec or
longer at the time of V.SCAN.)
Auto white : Auto white balance function cannot be
started.
Auto iris : Stops at the iris value at that time.
ALC : Stops at the sensitivity at that time.
To use a shutter speed of 2 sec or longer, use with the
following settings selected: (However, 1.000 sec or longer
at the time of V.SCAN.)
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.
Attention should be paid to the picture quality when the
sensitivity is raised since the image becomes coarse.
