Resolution and ROI frame rates
Resolution and ROI frame rates
This section charts the resulting frame rate from changing sensor region of
interest (ROI), from full image to a single line.

Note

• Frame rate data was generated using
StreamBytesPerSecond = 124 MB/s and an 8 bit pixel
format such as Mono8 or BayerRG8. Frame rates may be
lower if using network hardware incapable of 124 MB/s.
• The camera frame rate can be increased by reducing the
camera's Height attribute, resulting in a decreased
region of interest (ROI) or “window”.
• The camera frame rate can also be increased by increas-
ing the camera's BinningY attribute, resulting in a verti-
cally scaled image (less overall height with same field of
view).
• There is no frame rate increase with reduced width.
