Frame rates with rolling shutter sensors
The following table shows how the shutter type impacts available frame rates.
Reducing the area for ROI reduces readout time. The relations in
Table 16
apply
only if exposure time is shorter than readout time.

Delays
• 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.
