13.4 Acquisition Control 111
TriggerOverlap[TriggerSelector] triggerOverlap Specifies the type trigger overlap
permitted with the previous frame.
TriggerOverlap is only intented for
external trigger (which is usually
non-overlapped: i.e. exposure and
readout are sequentially). This
leads to minimal latency / jitter be-
tween trigger and exposure.
However, the camera accepts a
new trigger (the exposure time ear-
lier) before the end of the transmis-
sion 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).

ExposureMode exposureMode Sets the operation mode of the Ex-
posure (or shutter).
ExposureTime exposureTime Sets the Exposure time (in mi-
croseconds) when ExposureMode
is Timed and ExposureAuto is Off.
ExposureAuto exposureAuto Sets the automatic exposure mode
when ExposureMode is Timed.

Additionally, MATRIX VISION offers numerous additional features like:
• mvShutterMode
which selects the shutter mode of the CMOS sensors like rolling shutter or global shutter.
• mvDefectivePixelEnable
which activates the sensor's defective pixel correction.

• mvExposureAutoSpeed
which determines the increment or decrement size of exposure value from frame to frame.
• mvExposureAutoDelayImages
the number of frames that the AEC must skip before updating the exposure register.
