1.18 Use Cases 123
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 Control -
>
Acquisition Mode" "MultiFrame" and you have to set the
"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).
Figure 1: Starting an acquisition after one trigger event
For this scenario, you have to use the "Setting -

>
Camera -
>
Acquisition Control -
>
Trigger Selector"
"AcquisitionStart" .
The following figure shows, how to set the scenario shown in Figure 1 with wxPropView (p. 65 )
