To better understand these calculations, let’s look at an example. Suppose that you are working
with an 800 (H) x 600 (V) area of interest, that there are 215 rows above the AOI and that you
want a 2 ms. exposure. The calculations would look like this:
and:
So in this case, you can run the camera at up to 17.2 frames per second and still see the full effect
of the low smear feature.
If the camera’s actual frame rate is higher than the maximum allowed frame rate, the smearing
will come back. When you exceed the maximum allowed frame rate by a small amount, the upper
part of the image will show partial smearing (see Figure 3-16). As the frame rate is increased, the
smearing will become worse.
