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.

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.

"Setting -

. In Figure 2, the start condition is a
