7.6.5.1 ExposureActiveDelay
As previously stated, the Timer feature can be used to start the connected illumination
earlier than the sensor exposure.
This implies a timer conguration as follows:
▪ The ash output needs to be wired to the selected internal Timer signal.
▪ Trigger source and trigger activation for the Timer need to be the same as for the
sensor exposure.
▪ The TimerDelay feature (t
TimerDelay
) needs to be set to a lower value than the trigger
delay (t
triggerdelay
).
▪ The duration (t
TimerDuration
) of the timer signal should last until the exposure of the sensor
is completed. This can be realized by using the following formula:
t
TimerDuration
= (t
triggerdelay
– t
TimerDelay
) + t
exposure
7.6.6 Timer
Timers were introduced for advanced control of internal camera signals.
The timer conguration includes four components:
Setting Description
Timeselector There are one timer. Own settings for this timer can be
made. (Timer1).
TimerTriggerSource This feature provides a source selection for each timer.
TimerTriggerActivation This feature selects that part of the trigger signal (edges or
states) that activates the timer.
TimerDelay This feature represents the interval between incoming trig-
ger signal and the start of the timer.
(0 μsec .. 2 sec, step: 1 μsec)
TimerDuration By this feature the activation time of the timer is adjustable.
(10 μsec .. 2 sec, step: 1 μsec)
Different Timer sources can be used:
