Sequential readout
By default the camera continuously delivers images as fast as possible ("Free-running mode") in the sequential
readout mode. Exposure time of the next image can only start if the readout time of the current image is finished.
Figure 14: Timing in free-running sequential readout mode
When the acquisition of an image needs to be synchronised to an external event, an external trigger can be used. In
this mode, the camera is idle until it gets a signal to capture an image.

Simultaneous readout (interleave exposure)
To achieve highest possible frame rates, the camera must be set to "Free-running mode" with simultaneous readout.
The camera continuously delivers images as fast as possible. Exposure time of the next image can start during the
readout time of the current image.
Figure 16: Timing in free-running simultaneous readout
mode (exposure time is greater than readout time)
Figure 17: Timing in free-running simultaneous readout
mode (exposure time is greater than than readout time)
When the acquisition of an image needs to be synchronised to an external event, an external trigger can be used. In
this mode, the camera is idle until it gets a signal to capture an image.
