Q Electronic Shutter Mode Setting
[Shutter Mode: Step, S/Scan, ELC]
Step: Electronic shutter operates at the speed selected
by the Electronic Shutter Step/Synchro Scan
Setting.
S/Scan (Synchro Scan):
Electronic shutter operates at the speed selected
in Electronic Shutter Step/Synchro Scan Setting.
ELC: Electronic shutter is controlled to automatically
adjust the luminance.
Note
If Frame 1 is selected in CCD Read Out Mode Setting
(p), Electronic Shutter Mode Setting cannot be added.
R Electronic Shutter Step/Synchro Scan Setting
[Step/Synchro: OFF, 1/120 to 1/10000 (Step),
50.24 Hz to 15.63kHz (Synchro Scan)]
This setting is possible only when Step or Synchro Scan
is selected in Electronic Shutter Mode Setting.
• When "Step" has been selected as the electronic
shutter mode setting:
OFF: Electronic shutter is turned off.
1/120, 1/250, 1/500, 1/1000, 1/2000, 1/4000, 1/10000:
Electronic shutter operates at one of these
speeds as selected.
• When "Synchro Scan" has been selected as the
electronic shutter mode setting:
Bar noise can be reduced by synchro-scan adjustment
in shooting workstation scenes, for example.
For luminance setting at each shutter speed and synchro-
scan shutter speed, refer to the table below.

Notes
• In case of using the RCU (RCB), none of the shutter
speeds — 1/250, 1/2000, 1/4000, and 1/10000 can be
selected.
• In case of using the hybrid control panel, only OFF,
1/120, or ELC can be selected.
• If the lens iris switch is at M (Manual) when operating
the camera alone or when the iris switch on the RCU
(RCB) is at AUTO, ELC may not function. Set the lens
iris switch to A (Auto).
• Flickering may increase at ELC under fluorescent lights.
