Image Acquisition Control

Basler scout GigE

Example

Assume that you are using an scA640-70gm 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 = 84.4 frames/s

Formula 2:

Max Frames/s = 477.3 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 84.4 frames per second.
