Controls the acquisition rate (in
Hertz) at which the frames are cap-
tured.
Some cameras support a special
internal trigger mode that allows
more exact frame rates. This fea-
ture keeps the frame rate constant
to an accuracy of +/-0.005 fps at
200 fps. This is achieved using
frames with a length difference of
up to 1 us. Please check in the
sensor summary (p. 54) if this fea-
ture exists for the requested sen-
sor.
Selects the type of trigger to con-

case about mvTimestampReset

Specifies the type trigger overlap
permitted with the previous frame.
TriggerOverlap is only intended for
external trigger (which is usually
non-overlapped: i.e. exposure and
readout are sequentially).
leads to minimal latency / jitter
between trigger and exposure.
However, the camera accepts a
new trigger (the exposure time
earlier) before the end of the trans-
mission of the current image.
Maximum frame rate in
triggered mode = frame
rate of continuous mode
This however leads to higher la-
tency / jitter between trigger and
exposure.
A trigger will be not latched if it oc-
curs before this moment (trigger is
accurate in time).
