*1 This is an external input signal. Make sure to input
both HD and VD signals.
*2 Exposure time (Te)
Te = Trigger pulse width + 8 µ sec
(The effective trigger pulse width for the external
trigger shutter operation is between 2 µ s and 1/4
s.)
*3 Normal operation is resumed when the trigger
pulse width is 1/3 s or more. The trigger falling
edge restores external trigger shutter operation. At
this time, the 50 ms after the falling edge of the
trigger pulse is an external trigger input inhibition
area. There is no guarantee of operation for any
trigger input in this period.

*4 If there is a falling edge on the external VD within
a period of +10 µ s from the falling trigger edge (1
and 2 in the figure), it is not defined whether the
image is output for the external VD falling edge or
the image is output for the next external VD falling
edge. (1 in the figure shows that the image is
output for the next external VD. 2 shows the
image for the external VD.) In any other case, the
image is output for the external VD falling edge
after the trigger falling edge (3 in the figure).
Note
An image is not output correctly when the next trigger is
input before the image for the previous trigger has been
output.
