Resolution and ROI frame rates
Resolution and ROI frame rates
This section provides the performance information which identifies the impact
of reducing the region of interest on the camera’s maximum frame rate.
Prosilica GE680
Note

• Frame rate data was generated using StreamBytesPer-
Second = 124 MB/s and an 8 bit pixel format such as
Mono8, BayerGR8, 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.
