AcquisitionMode acquisitionMode Sets the acquisition mode of the
device. There are different modes
available with GenICam (p. 155)
and provides the opportunity that
the camera sends
• exactly one image ("←-
SingleFrame"),
• exactly the set number of
frames ("MultiFrame") or
• it acquire live images ("←-
Continuous").
and can be used for asyn-
chronously grabbing and sending
image(s). It works with internal
and external hardware trigger
where the edge is selectable. The
external trigger uses Image←-
RequestTimeout (ms)to time out.
• The chapter How to see
the first image (p. 79) shows
how to acquire images with
wxPropView (p. 74).
• The use case Acquiring a
number of images (p. 166)
shows how to acquire a num-
ber of images; also triggered
externally.
AcquisitionStart acquisitionStart Starts the Acquisition of the device.
AcquisitionStop acquisitionStop Stops the Acquisition of the device
at the end of the current Frame.
AcquisitionAbort acquisitionAbort Aborts the Acquisition immediately.
AcquisitionFrameRate
acquisitionFrameRate Controls the acquisition rate (in
Hertz) at which the frames are cap-
tured.
Some cameras support a special
internal trigger mode that allows
more exact frame rates. This fea-
ture keeps the frame rate constant
to an accuracy of +/-0.005 fps at
200 fps. This is achieved using
frames with a length difference of
up to 1 us. Please check in the
sensor summary (p. 64) if this fea-
ture exists for the requested sen-
sor.
TriggerSelector triggerSelector Selects the type of trigger to con-
figure.
A possible option is mv←-
TimestampReset. The use
case about mvTimestampReset
is available (p. 271).
