Image Acquisition Control
9.7
Maximum Allowed Frame Rate
In general, the maximum allowed acquisition frame rate on any dart BCON camera can be limited
by these factors:
The exposure time for the acquisition of frames. If you use very long exposure times, you can
acquire fewer frames per second.
The amount of time it takes to read an acquired frame out of the imaging sensor and to prepare
it for transmission out of the camera. The amount of time varies with the size of the frame.
Frames with a smaller height take considerably less time. Frames with a smaller width may
also take slightly less time.
The amount of time it takes to transmit an acquired frame from the camera to the target
system. The amount of time depends on the target system's capacity limits for data transfer
and the bandwidth assigned to the camera.
Under certain conditions, overlapping image acquisition is not possible. This decreases the
camera's maximum allowed frame rate. For more information about overlapping image
acquisitions, see Section 9.5 on
To determine the maximum allowed acquisition frame rate with your current camera settings, use
the Basler pylon API to read the value of the camera's ResultingFrameRate parameter. For more
information, see Section 9.7.1 on
When the camera's acquisition mode is set to single frame, the maximum possible
acquisition frame rate can't be achieved. This is because the camera performs a
complete internal setup cycle for each single frame and because it can't be
operated with overlapped exposure.
For more information about overlapped image acquisitions, see Section 9.5 on

Using the Basler pylon API to Check the
Maximum Allowed Frame Rate
You can use the Basler pylon API to read the current value of the ResultingFrameRate parameter
from within your application software using the Basler pylon API. The following code snippet
illustrates using the API to get the parameter value:
// Get the resulting frame rate
double d = camera.ResultingFrameRate.GetValue();
The ResultingFrameRate parameter takes all camera settings into account that can influence the
frame rate and indicates the maximum allowed frame rate given the current settings.
