4. Shutter setting
You can use the electronic shutter to set to the exposure
time.
Furthermore, when the exposure output setting
(command: WEN-STRB 2) is selected for the 10th pin
signal output terminal of the DC IN connector (12-pin
connector), Hi is output for the exposure period. The
shutter has preset shutter settings in which the exposure
time is fixed, and an arbitrary shutter setting that can be
set in increments of 1 µs or clock units (27.78 ns). Use
of the overlap function allows for preventing the
inclusion of noise even if one of the following triggers is
input during image transmission.
4.1.
Preset shutter
You can set 16 types of exposure time ranges from OFF
to 2 s.
The settable shutter value differs depending on the
mode. Refer to the following table.
a
: Settable
–
: Not settable
f
: Depends on the number of lines configured for
PARTIAL.
*1 The trigger signal period must be longer than the shutter
speed.
Shutter OFF is the same as 1/15 s.
*2 If the partial starting position for display is
≥
32, set the
ending position to a value
≥
504.
If the partial starting position for display is > 32:
set the number of lines displayed to a value
≥
472 if the
“starting position for display - 33 = a multiple of 8” or set
the number of lines displayed to a value
≥
473 if the
“starting position for display - 33
≠
a multiple of 8.”
