Abstract

A system and method are provided for a “multi-region” autofocus video tool-type or mode within a machine vision inspection system. The user may efficiently define multiple regions of interest that are grouped as a “multi-region” set. The autofocus operations for the multi-region set are defined with a shared set of autofocus parameters. The same set of autofocus images may be used for the autofocus operations of the multi-region set. The user may conveniently also define individual autofocus regions of interest, defined with individual autofocus parameters, within the same field of view. Various user interface features allow a user to conveniently change between the individual autofocus tool-type or mode and the multi-region autofocus tool-type or mode.
