Figure 5
Illustration of the four possible different modes using the start or end of the enable signal to trigger the acquisition of predefined frame series, both for the (a) physical enable and (b) virtual enable schemes. The fixed number of frames to be taken has been set to N = 4. Note that the frame store signal is not shown in (a) since it is identical to the exposure trigger signal. The exposure trigger in this example is assumed to be produced internally by the camera at constant frequency (auto trigger). Due to the different timing of the trigger pulses between the physical and virtual enable schemes, the exact frame timing is different for both cases.
