Imaging-based bar code symbol reading system permitting modification of system features and functionalities without detailed knowledge about the hardware platform, communication interfaces, or user interfaces

摘要

Disclosed is an image capture and processing system that supports manufacturer-constrained system behavior modification by the end_user through the development and installation/deployment of plug-in modules within the application layer of the system by a person other than the system designer, so as to allow this person to flexible modify prespecified features and functionalities of the system, and thus satisfy customized end-user application requirements, but without requiring detailed knowledge about the hard-ware platform of the system.
