Basler racer Camera Link 74
Fig. 23: Exposure N+1 Illegally Starts Before the Exposure Overhead for the Preceding Line Acquisition N Has
Ended; the Shown Overlap of Readouts is Also Illegal; Timed Exposure Mode Used as an Example
Fig. 24: Exposure N+1 Illegally Ends Before Readout of the Preceding Line Acquisition N Has Ended; Applies to
Trigger Width Exposure Mode Only
When the line start trigger has illegally gone low to end the exposure for line acquisition N+1 before
readout for acquisition N has ended (in trigger width exposure mode; see Fig. 24), the camera will
behave as shown in Fig. 25: The camera will extend the exposure and end it when the next valid
trigger for ending exposure occurs.
