This is a signal input from the outside. The trigger interval should be trigger pulse width + 1 field + 2H period or more. The trigger interval shorter than described above cannot be ensured. If a trigger pulse is not input under the prescribed conditions, the normal operation is ensured several V after a change in input operation under the prescribed conditions.
Exposure time Te Te = Trigger width + 97 μs
Te = Trigger width + 120 μs
The normal operation state is engaged when the high period exceeds 1/3 sec. After that, the external trigger shutter operation is engaged when the trigger pulse goes “low”. In this case, the area between the falling edge of a trigger pulse and the subsequent 50 ms period is an external input inhibition area. During the trigger inhibit period, an input trigger may be missed.
A VD signal is generated 1H to 2H after a trigger pulse falls, and an image is output in synchronization with the VD signal.
When the external trigger shutter mode changes into the normal operation mode, a WEN signal is output.
