Acquiring Image Data
The core of any image acquisition application is the data acquired from the input
device. A trigger is the event that initiates the acquisition of image frames, a process
called logging. A trigger event occurs when a certain condition is met. For some types
of triggers, the condition can be the execution of a toolbox function. For other types of
triggers, the condition can be a signal from an external source that is monitored by the
image acquisition hardware.
The following topics describe how to configure and use the various triggering options
supported by the Image Acquisition Toolbox software and control other acquisition
parameters.
