Rolling Shutter
On cameras equipped with a rolling shutter, the pixel lines are exposed with a temporal offset
(called tRow) from one line to the next. When frame start is triggered, the camera begins exposing
the top line of pixels of the AOI (line one). Then, the camera begins exposing line two tRow later.
And so on until the bottom line of pixels is reached. See Figure 5. The exposure time is the same
for all lines.

The use of an additional light source (strobe) is recommended in situations where fast movements
are being recorded with rolling shutter cameras as images of fast-moving objects can be blurry
otherwise due to the temporal shift in the start of the exposure of the individual lines. There are two
ways to trigger this additional lighting:
 Flash Window Signal = triggers a short strobe pulse (= flash).
 Exposure Active Signal = triggers a light source that allows a longer illumination period.
