Image Acquisition Control
Basler pioneer 139
For more information about setting the exposure time, see Section 10.4 on page 127.
Formula 3:
Calculates the maximum frame rate based on the frame transmission time:
Example
Assume that you are using a piA640-210gm camera set for an exposure time of 2000 µs and for
600 x 400 resolution. Also assume that you have checked the value of the Device Current
Throughput parameter and the Payload Size parameters and found them to be 110000000 and
240000 respectively.
Formula 1:
Max Frames/s = 248.4 frames/s
Formula 2:
Max Frames/s = 488.5 frames/s
Formula 3:
Max Frames/s = 458.3 frames/s
Formula one returns the lowest value. So in this case, the limiting factor is the sensor readout time
and the maximum allowed acquisition frame rate would be 248.4 frames per second.
