The Trigger Overlap feature defaults to
Readout
, which means Trigger Overlap is enabled,
and allows an exposure to occur during the image readout of the previous frame. Change the
Trigger Overlap behavior by setting the Trigger Overlap control in Vision Builder AI, setting
the Trigger Overlap attribute in LabVIEW, or by setting the Trigger Overlap in the attribute
tree in MAX.
Reconfiguring During an Acquisition
Many attributes can be reconfigured while an acquisition is in progress. Some of these
attributes, including all of the Analog Controls and the Exposure attributes, directly affect the
content of the image. The attribute values are latched when an image is placed into the
acquisition queue. Image queuing is managed by the driver without direct interaction from the
user.
If any of these values are changed while the ISC-178x is waiting on a trigger, the settings will
not be applied to the currently queued image. The first image acquired after changing the
settings will still use the old configuration, and the new configuration will begin with the
subsequent image. These conditions only apply when changing the configuration during an
acquisition. When the camera is configured prior to starting the acquisition, all images will be
acquired using the current settings.
