( 1 ) SHUTTER (Electronic shutter)
The electronic shutter has four modes; MANU (Manual), SS (Synchro. Scan), E.TRG (External trigger), and AUTO
(Auto Shutter).
Move the “ ” to “MODE” and push [DATA UP], [DATA DOWN] button to select the desired mode among “MANU”, “SS”,
“E.TRG”, and “AUTO”.
MANUAL : It is possible to select the exposure time from nine speed setting; OFF, 1/250s, 1/500s, 1/1000s,
1/2000s, 1/4000s, 1/10000s, 1/24000s (NORMAL) or 1/27000s (FAST), 1/36000s (NORMAL) or
1/39000s (FAST).
When not using the electronic shutter, select OFF.
Note:
When setting a rapid shutter speed, sensitivity degrades according to the speed.
When a discharging light such as fluorescent lamp, etc. is used for the illumination, the flicker
may be excessive.
SS : Shutter speed can be set by the horizontal scanning time (1H) unit or by the number of frames.
E.TRG : Exposure is performed and images are output by external trigger. E.TRG includes the three modes
described below. (For details of specifications, refer to the item “7.4 E.TRG (External trigger)”.)
• 1P SR (1 Pulse Sync Reset)
The charge begins to accumulate to each CMOS pixels after the trigger pulse is received.
Upon completion of accumulation the vertical sync signal is reset and 1 frame images are output.
The exposure/accumulation time can be set from 0.03 to 16 ms. The trigger signal timing can be
set to either the rising or falling edge.
• PW SR (Pulse width trigger Sync Reset)
The charge begins to accumulate to each CMOS pixels after the trigger pulse is received.
Upon completion of accumulation the vertical sync signal is reset and 1 frame images are output.
This is the mode to set the exposure period by the pulse width of the trigger.
The trigger signal polarity can be set to either the positive or negative polarity.
• RR (Reset restart)
Input of an external reset-restart signal permits one screen of information to be output at an arbi-
trary timing.
AUTO : Exposure time is automatically controlled to obtain the specified video level.
