Abstract

Embodiments of a method, apparatus, and article of manufacture for rapidly capturing images in an automated identification system to effectively extend one dimension of a field of view of an image system are disclosed herein. In one embodiment, the image system captures and processes multiple images of at least a portion of a surface of a component in the automated identification system in response to a trigger signal communicated from a triggering device configured to sense a location of the component. Various embodiments of the invention include multiple sources for capturing images, and/or multiple user-specified schemas for effectively extending the field of view of the image system along the axis of component travel in the automated identification system.
