PreStrobe_us Parameter
PreStrobe_us is expressed in microseconds. Its function is to advance the leading edge of strobe pulse.
In following examples, consider the values:
- StrobeMode=MAN
- TrueExp_us=200
- StrobeDur=50
- StrobePos=75
This situation is drawn below. Consequently, the duration of strobe pulse is 100 μs. The leading edge of strobe pulse appears 75 μs after the beginning of exposure.
The usage of PreStrobe_us parameter allows to start earlier the strobe pulse.
A first example with PreStrobe_us=50 is drawn below.
The leading edge of strobe pulse appears 25 μs after the beginning of exposure.
Increasing PreStrobe_us can lead to begin the strobe pulse before the exposure starts.
A second example with PreStrobe_us=100 is drawn below. In this case, the strobe pulse begins 25 μs before the exposure starts.
