path
HoldImg mode
By
setting
the
HoldImg
flag,
transport
of
the
image
over
the
IEEE1394
bus
is
stopped
completely.
All
captured
images
are
stored
in
the
internal
ImageFiFo
.
The
camera
reports
the
maximum
possible
number
of
images
in
the
FiFoSize
variable.
The
following
screenshot
shows
the
sequence
of
commands
needed
to
work
with
deferred
mode.
Note
•
Pay
attention
to
the
maximum
number
of
images
that
can
be
stored
in
the
image buffer
.
If
you
capture
more
images
than
the
number
in
FiFoSize
,
the
oldest
images
are
overwritten.
•
The
extra
SendImage
flag
is
set
to
true
to
import
the
images
from
the
camera.
The
camera
sends
the
number
of
images
set
in
the
NumOfImages
parameter.
•
If
NumOfImages
is
0,
all
images
stored
in
the
image
buffer
will
be
sent.
•
If
NumOfImages
is
not
0
,
the
corresponding
number
of
images
will
be
sent.
•
If
the
HoldImg
field
is
set
to
false
,
all
images
in
ImageFIFO
will
be
deleted.
No
images
will
be
sent.
•
The
last
image
in
the
image
buffer
will
be
corrupted,
when
simultaneously
used
as
input
buffer
while
being
read
out.
In
this
case
read
out
one
image
less
than
maximum
buffer
size.
•
NumOfImages
is
incremented
after
an
image
was
read
out
of
the
sensor
and
therefore
stored
into
the
onboard
image
buffer.
•
NumOfImages
is
decremented
after
the
last
isochronous
packet
of
an
image
was
handed
over
to
the
IEEE1394
chipset
of
the
camera.
