8.5.3. Continuous operation
For applications not requiring asynchronous external trigger, but where a continuous stream of
images is required, this mode should be used.
In this mode it possible to use an auto-iris lens (video drive). The CV-M9GE provides an auto-iris
lens video signal at pin 4 of the 12-pin Hirose connector.
For timing details, refer to fig. 16. through fig. 22
.

8.5.4. Edge Pre-select Trigger Mode
An external trigger pulse initiates the capture, and the exposure time (accumulation time) is the
fixed shutter speed set by registers. The accumulation can be LVAL synchronous or LVAL a-
synchronous.
The resulting video signal will start to be read out after the selected shutter time.
For timing details, refer to fig. 16. through fig. 22. and fig. 27.

Important notes on using this mode
Trigger pulse >2 LVAL to <1 FVAL)
Minimum trigger interval in synchronous accumulation mode
In case R,G and B exposure is common :
≥
(1 FVAL(792L) + 1 LVAL)
In case R,G and B exposure is individual :
≥
(Max. Exp. time – Min. Exp. time) + 1 FVAL (792L) + 1 LVAL
Minimum trigger interval in a-synchronous accumulation mode
≥
( exposure time + 1 FVAL(792L) + 1 LVAL).
Minimum trigger interval in Smear-less ON:
≥
(Smear-less time (198L) + Max. Exp. time + 1FVAL(792L) + 1 LVAL
Minimum trigger interval with Sequential Mode together
In case the same R,G and B shutter value for all sequences, and SYNC mode
≥
1 FVAL (792L) + 1L
In case the same shutter for each sequence, ( SYNC/a-SYNC )
≥
Maximum Ex 1 FVAL (792L) + 1L
In case the different shutter for R,G and B, ( SYNC/a-SYNC )
≥
(Max. Exp. time – Min. Exp. time) + 1 FVAL (792L) + 4 LVA
