Triggering and sensor shutter types
Triggering behavior differs between cameras with global shutter (GS) and
electronic rolling shutter (ERS).
Triggering
The following table shows how the shutter mode impacts available frame rates:

Table 12: Frame rates depending on shutter modes and trigger modes
Achieved frame rates may not match specified values
• Some sensors have an exposure start jitter that may reduce maximum frame
rates.
• Your individual setup may cause delays in data transmission.
Bandwidth adjustments
Consider the bandwidth available for camera payload depends on your individual
hardware, the operating system, software and drivers, and your application. We
recommend you to adjust
DeviceLinkThroughputLimit
to your requirements.
Interdependencies between ROI and ExposureTime values
Changing parameters for ROI can affect values for
ExposureTime
, such as
minimum, maximum, and increments, but
ExposureTime
itself as well. We
recommend you to set:
• ROI values
• DeviceLinkThroughputLimit
before you set values for
ExposureTime
.
Value changes by feature interdependencies
