TElectronic 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 (u), Electronic Shutter Mode Setting cannot be added.
UElectronic Shutter Step/Synchro Scan Setting [Step/Synchro: OFF, 1/100 to 1/10000 (Step), 60.34 Hz to 15.75kHz (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.
1/100, 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

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, 1/100, 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.
