Resolution and ROI frame rates
The Prosilica GX camera can be operated near peak sensor frame rates even
when using a single port connection. The frame rate vs. height graphs included
in this section provide frame rate performance results for both single GigE port
and Dual GigE LAG configurations at 8-/16-bit output formats.
Note
For some GX cameras, e.g. GX1910, GX2300, bandwidth limit-
ing occurs even in 8-bit pixel formats, although not as severely
as with a 16-bit pixel format.
Note
•
Frame rate data was generated using
StreamBytesPer-
Second = 124 MB/s
and 8-/16-bit pixel format
– 8-bit pixel formats: Mono8, BayerRG8, or BayerGR8
– 16-bit pixel formats: Mono12, BayerRG12, or Bayer-
GR12
Frame rates may be lower if using network hardware inca-
pable of 124 MB/s.
•
ROIs are center image, where attribute
RegionY = (full
sensor height – ROI height)/2
, for maximum speed
advantage on a quad-tap CCD sensor.
•
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.
