Use Cases
This chapter shows some typical configurations of the camera. It gives some tips, how to
acquire images, how to use the general purpose counters and timers and how to configure the
look up table.
C.1 Acquisition
This section shows some configuration procedures of frequently used acquisition situations.
C.1.1 Camera runs in "free-running" mode
The camera needs to start acquiring images as fast as possible as soon as the command
AcquisitionStart() has been performed. The following configuration procedure must be
applied:
1. The TriggerMode of the AcquisitionStart-, FrameStart-, FrameBurstStart- and
ExposureStart-trigger must be set to Off.
2. Parameter EnAcquisitionFrameRate must be set to False.
3. The required image Width and Height must be set.
4. The required PixelFormat must be set.
5. AcquisitionMode must be set to Continuous.
6. The software command AcquisitionStart() must be applied.
C.1.2 Camera runs in "constant frame rate" mode
In some application it is necessary, that the camera acquires image at a certain frame rate. This
mode is similar to the "free-running" mode, however a required frame rate can be configured
additionally. The following configuration procedure shows how to set the camera in the
constant frame rate mode:
1. The TriggerMode of the AcquisitionStart, FrameStart, FrameBurstStart- and ExposureStart
trigger must be set to Off.
2. Parameter EnAcquisitionFrameRate must be set to True.
3. Either the AcquisitionFrameTime or AcquisitionFrameRate must be set accordingly.
4. The required image Width and Height must be set.
5. The required PixelFormat must be set.
6. AcquisitionMode must be set to Continuous
7. The software command AcquisitionStart() must be applied.
The "constant frame rate" mode provides two different acquistion frame rate settings:
ExposureControlled and FrameRateControlled:
• In ExposureControlled acquisition mode the maximal configurable frame rate at a given
ROI settings is limited by the exposure time. When the user increases the exposure time,
the camera decreases the frame rate automatically if necessary.
