Image Acquisition Control
Basler scout light 65
6.10 Maximum Allowed Acquisition Frame
Rate
(All Models Except slA750-60fm)
In general, the maximum allowed acquisition frame rate can be limited by three factors:
The amount of time it takes to read an acquired image out of the imaging sensor and into the
camera’s frame buffer (an acquired image is also known as a frame). This time varies
depending on the height of the frame. Shorter frames take less time to read out of the sensor.
The frame height is determined by the camera’s AOI settings.
The exposure time for acquired frames. If you use very long exposure times, you can acquire
fewer frames per second.
The number of packets needed to transfer an acquired frame from the camera to your PC.
To determine the maximum allowed acquisition frame rate with your current camera settings, you
can read the value of the camera’s Resulting Frame Rate parameter. This parameter indicates the
camera’s current maximum allowed frame rate taking the AOI, exposure time, and packet size
settings into account.
You can read the current value of the Resulting Frame RateAbs parameter from within your
application software by using the pylon API. The following code snippet illustrates using the API to
get the parameter values:
// Resulting Framerate
double resultingFps = Camera.ResultingFrameRateAbs.GetValue();
For detailed information about using the pylon API, refer to the Basler pylon Programmer’s Guide
and API Reference.
You can also use the Basler pylon Viewer application to easily set the parameters.
For more information about the pylon Viewer, see Section 3.1 on page 17.
For more information about the AOI settings, see Section 9.4 on page 111.
Note
The information in this section applies to all camera models except the
slA750-60fm. For information about slA750-60fm cameras, see Section 6.11 on
page 70.
