To guarantee the BayerParity start condition, the camera sends a FrameValid synchronization signal. Thus, you can
say that the camera behaves like a area-scan camera.
With Basler's camera control tool you can define the frame height (always a multiple of 2) and therefore the Frame←-
Valid signal.
In combination with a triggered image acquisition, you have to keep in mind that an image acquisition will start after
• a start trigger signal (e.g. a light barrier) and
• a valid FrameValid signal.
The mvHYPERION frame grabbers are suitable for these applications.
Figure 1: Triggered acquisition with area-scan cameras
Note
As you can see in Figure 1, there are trigger delays possible (up to an almost complete frame).
The trigger start condition (TriggerActivation) can be set via wxPropView (p. 48) in "Setting -> Base -> Camera ->
TriggerControls". In Figure 2, the start condition is a RisingEdge at the J4 connector.
