1.18 Use Cases

1.18.1 Introducing acquisition / recording possibilities

There are several use cases concerning the acquisition / recording possibilities of the camera:
• Acquiring a number of images (p. 123)
• Generating very long exposure times (p. 124)
• Working with multiple AOIs (mv Multi Area Mode) (p. 126)
• Working with Event Control (p. 130)

1.18.1.1 Acquiring a number of images

As described in chapter Acquisition Control (p. 69), if you want to acquire a number of images, you can use as
"Setting - Base - Camera -
"Acquisition Frame Count".
Afterwards, if you start the acquisition via the button "Acquire", the camera will deliver the number of images.
The "MultiFrame" functionality can be combined with an external signal to start the acquisition.
There are several ways and combinations possible, e.g.:
• A trigger starts the acquisition (Figure 1).
• A trigger starts the acquisition start event and a second trigger starts the grabbing itself (Figure 2).
For this scenario, you have to use the "Setting -
"AcquisitionStart".
The following figure shows, how to set the scenario shown in Figure 1 with wxPropView (p. 65)
