Syntax

imaqreset

Description

imaqreset deletes any image acquisition objects that exist in memory and unloads all adapters loaded by the toolbox. As a result, the image acquisition hardware resets.

imaqreset is the image acquisition command that returns MATLAB® to the known state of having no image acquisition objects and no loaded image acquisition adapters.

You can use imaqreset to force the toolbox to search for new hardware that might have been installed while MATLAB was running.

Note that you must not call imaqreset from any of the callbacks of a videoinput object, such as the start function callback or frames acquired function callback.
