C Use Cases
• In FrameRateControlled acquisition mode the max configurable exposure time depends
on the configured frame rate. When the user increases the frame rate, the camera
decreases the exposure time automatically if necessary.
C.1.3 Camera runs in triggered mode
The camera can be triggered by a software or hardware signal. In this mode, a frame is started
on every generated trigger signal. The following configuration procedure shows how to set
the camera in triggered mode:
1. The
TriggerMode
of
FrameStart
trigger must be set to
On
. The
AcquisitionStart
,
FrameBurstStart
and the
ExposureStart
must be set to
Off
.
2. The
TriggerSource
of the
FrameStart
trigger must be set to the corresponding source. For
instances to
Line0
.
3. Since the source is set to
Line0
, the
TriggerActivation
must be set accordingly:
RisingEdge
,
FallingEdge
or
AnyEdge
.
4.
TriggerDelay
and
TriggerDivider
of the
FrameStart
trigger must be set accordingly.
5. The required image
Width
and
Height
must be set.
6. The required
PixelFormat
must be set.
7.
AcquisitionMode
must be set to
Continuous
.
8. The software command
AcquisitionStart()
must be applied.
After these configurations, the camera is waiting for the corresponding signal edge of the
selected trigger source, in this case
Line0
.
It might be necessary to adjust the polarity of the
Line0
input signal. This can be done by the
parameter LineInvert in the section DigitalIOControl.
If the camera must be triggered by a software signal, there are two ways, how this can be
done:
• Set the TriggerSource of the FrameStart trigger to Software . A frame is started, when the
TriggerSoftware() command of the FrameStart trigger is applied.
• Set the TriggerSource of the FrameStart trigger to one of the eight software signals; for
instances SoftwareSignal0 . A frame is started, when the command TriggerSignalPulse() in
the section SoftwareSignalControl is applied (SoftwareSignalSelector must be set to
SoftwareSignal0 ).
C.1.4 Camera runs in burst triggered mode
If a certain number of images must be acquired on a single trigger input event, the cameras
frame burst start trigger feature can be used. The following configuration procedure shows
how to set the camera in burst triggered mode:
1. The TriggerMode of FrameBurstStart trigger must be set to On . The AcquisitionStart ,
FrameStart
and the
ExposureStart
trigger must be set to
Off
.
2. The
TriggerSource
of the
FrameBurstStart
trigger must be set to the corresponding source.
For instances to
Line0
.
3. Since the source is set to
Line0
, the
TriggerActivation
must be set accordingly:
RisingEdge
,
FallingEdge
or
AnyEdge
.
4.
TriggerDelay
and
TriggerDivider
of the
FrameBurstStart
trigger must be set accordingly.
