Configuration
of
the
camera
Time base
Corresponding
to
IIDC,
exposure
time
is
set
via
a
12-bit
value
in
the
corresponding
register
(SHUTTER_INQ
[51Ch]
and
SHUTTER
[81Ch]).
This
means
that
you
can
enter
a
value
in
the
range
of
1
to
4095.
Pike
cameras
use
a
time
base
which
is
multiplied
by
the
shutter
register
value.
This
multiplier
is
configured
as
the
time
base
via
the
TIMEBASE
register.
The
time
base
IDs
0
to
9
are
in
bit
[28]
to
[31].
See
296.
Default
time
base
is
20
µs:
This
means
that
the
integration
time
can
be
changed
in
20
µs
increments
with
the
shutter
control.
The
ExpOffset
field
specifies
the
camera
specific
exposure
time
offset
in
microseconds
(µs).
This
time
(which
should
be
equivalent
to
has
to
be
added
to
the
exposure
time
(set
by
any
shutter
register)
to
compute
the
real
exposure
time.
The
ExpOffset
field
might
be
zero
for
some
cameras:
this
has
to
be
assumed
as
an
unknown
exposure
time
offset
(according
to
former
software
versions).
