7.3.4 Pre-Select trigger mode
An external trigger pulse initiates the capture, and the exposure time (accumulation time) is
defined by the SH or PE commands.
The resulting video signal will start to be read out after the selected shutter time.
For timing details, refer to fig. 19 through fig. 26 and fig. 28.

Important Note:
1 The minimum width of the trigger is 2L. The minimum interval of trigger input is as
follows.
Output mode
IS=0 Sync
Smearless OFF FVAL(792L) + 3L+(Exposure time difference of BW1
and BW2)
Smearless ON
Smearless Time(198L) +1+ ( longer exposure time
between BW1 and BW2) + FVAL(792L) + 3L
Output mode
IS=1 Separate
Smearless OFF FVAL(792L) + 3L
Smearless ON
Smearless Time(198L) +1
+
FVAL(792L)+3L
FVAL(792L) is the FVAL period of continuous operation.

In the case that “Output mode” is set at “SYNC”, the trigger input for BW1 has priority.
The exposure time can be set individually, but the output timing is synchronized with the
rising edge of the longer exposure time.
