Continuous acquisition mode
If the exposure time is greater than the frame blanking time, the exposure time and the readout time will
be overlapped. As shown in the Figure 8-21.
Trigger acquisition mode
When the interval between two triggers is less than the sum of exposure time and the readout time, it will
occur overlap exposure, as shown in Figure 8-22.

Compared with non-overlap exposure mode, in overlap exposure mode, the camera can obtain higher

Set Exposure Mode
Two Exposure Mode are available: Timed exposure mode and TriggerWidth exposure mode. Among them,
the TriggerWidth exposure mode determines the exposure time when the camera is configured for
hardware triggering. And the exposure time depends on the width of the trigger signal, which is triggered
by the rising edge (falling edge) set by the Trigger Activation.

Timed exposure mode
Timed exposure mode is available on all camera models. In this mode, the exposure time is determined
by the camera's Exposure Time setting. If the camera is configured for software triggering, exposure starts
when the software trigger signal is received and continues until the exposure time has expired.
If the camera is configured for hardware trigger:
If rising edge triggering is enabled, exposure starts when the trigger signal rises and continues until
the exposure time has expired, as shown in Figure 8-23
