Abstract:
1. A digital-imaging based code symbol reading system comprising: a housing having a light transmission window; a digital image formation and detection subsystem, disposed in said housing, and having (i) image formation optics for projecting a field of view (FOV) through said light transmission window and upon an object to be imaged in said FOV, and (ii) an area-type image detecting array for detecting imaged light reflected off the object during illumination operations in an image capture mode in which rows of sensor elements in said area-type image detecting array are enabled so as to detect one or more 2D digital images of the object formed on said area-type image detecting array; an illumination subsystem, disposed in said housing, and having an illumination array for producing and projecting a field of illumination through said light transmission window and within said FOV during the image capture mode; an illumination control subsystem disposed in said housing, for controlling the operation of said illumination subsystem during said image capture mode; an image capturing and buffering subsystem disposed in said housing, for capturing and buffering said one or more 2D digital images detected by said image formation and detection subsystem; a digital image processing subsystem disposed in said housing, for processing said one or more 2D digital images captured and buffered by said image capturing and buffering subsystem, so as to read one or more 1D and/or 2D code symbols graphically represented therein, and producing symbol character data representative of said read one or more 1D and/or 2D code symbols; an input/output subsystem for transmitting said output data to an external host system or other information receiving or responding device; a system control system for controlling and/or coordinating the operation of said subsystems above; and a computing platform for supporting the implementation of one or more of said subsystems above, and including (i) memory for storing at least one code symbol reading application, and (ii) a microprocessor for running at least one code symbol reading application; and wherein said memory comprises a memory architecture that supports a multi-tier modular software architecture characterized by an Operating System (OS) Layer having automatic login, and an Application Layer in which at least one said code symbol reading application is automatically run, and being responsive to the generation of a triggering event within said digital-imaging based code symbol reading system.
