Second, you need to calculate the maximum recommended frame rate for low smear using this
formula:
If you use an example with a 2000 µs exposure time and a 1392 (H) x 600 (V) area of interest, the
calculations look like this:
T(f) = ( 600 x 51.2281 µs ) + 9941.0 µs
T(f) = 40677.86 µs
and:
If the camera’s actual frame rate is higher than the maximum
recommended frame rate, the smearing will come back.
When you exceed the maximum recommended frame rate
by a small amount, the upper part of the image will show
partial smearing (Figure 3-12). As the frame rate is
increased, the smearing will become worse.
