Strobe valid time
As shown in Figure 3-21, Strobe is set to high level. When exposure starts, Strobe will
output immediately. Strobe Line Duration value decides the Strobe duration: when the
Strobe Line Duration value is 0, the Strobe duration is equal to the exposure time;
when the Strobe Line Duration value is not 0, the Strobe duration is equal to Strobe
Line Duration value.

Strobe output delay
The camera supports the function of Strobe signal output delay to satisfy special
application: as shown in Figure 3-22, when exposure starts, the Strobe output is not
valid immediately. Instead, the Strobe output will delay according to the setting in
Strobe Line Delay.

Strobe pre-trigger
Support Strobe pre-trigger. Strobe signal is valid before the sensor exposure. This
function can apply to the LED light that takes time to be stable after starting. It is
necessary for a stable light source when capturing images. Pre-trigger time can be set
