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.

Prosilica GC650

Note



• Frame rate data was generated using StreamBytesPer-

Second = 124 MB/s and an 8-bit pixel format such as

Mono8, BayerBG8, 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.
