In this mode, the exposure is conducted synchronizing with the trigger pulse. In the case that the high-true logic is selected, the
actual exposure occurs when the trigger signal is at high state. The camera exposure starts at the rising edge of the trigger signal
and stops at the falling edge of the trigger signal. If the next pulse is receipt during the video out period, the image signal is swept
out in midstream and can’t normally get image signal,

Camera operation
mode
* The camera does not switch to continuous shutter mode when the low speed shutter is selected.
* It is V reset at the next internal HD timing immediately after the exposure is finished.
* The exposure time is controlled by the pulse width of the trigger signal.
* When switched to asynchronous shutter mode from continuous shutter mode, the waiting period of at least 1VD is required if the
shutter speed is less than 1 VD.
