(!) With the conventional products, the pulse width operation mode is always enabled when "9" is selected for the shutter
switch in the asynchrony shutter mode. Carefully note that this camera, however, will be in the preset shutter mode
when "PWC=DISABLED (prohibited)" is set, even if the shutter switch is positioned at "9".
[Terminology] High speed shutter ····· This means the shutter of which shutter speed is shorter than 1 frame duration(=1

Table 5-1. Description of electronic shutter operation modes
Electronic shutter is not used.
Exposure time of imager device is equivalent to one frame duration.
Exposure is continuously performed for each frame.
Repeats exposure regardless of external trigger input (Vinit).
Repetition pitch is per frame.
Electronic shutter is released each time the external trigger is input (Vinit).
The permissible shortest repetition pitch is [exposure time + 1 frame duration].
Shutter, the exposure time of which is less than one frame, is used.
The shutter speed can be set as a preset shutter speed at 9 different levels both for the
continuous shutter/asynchronous shutter mode.
(!) As for the shutter speed of the conventional FC series cameras, 8 different levels for the
asynchronous shutter mode.
The shutter, the exposure time of which is two frames or over, is used.
(Only for continuous shutter mode) The shutter speed can be set as a preset shutter speed at 9
different levels.
(Note) This camera allows this setting only for the continuous shutter mode.
In case of the asynchronous shutter setting only, the shutter, shutter speed of which
corresponds to the pulse width (during an effective level) of the external trigger input (Vinit) ,
is released.
Shutter speed can be set as nH (n = 1 or larger integer number) in H (horizontal synchronous
time) unit.
