Abstract

A method of illuminating objects on a countertop surface using an automatically-triggered digital image capture and processing system having a single array of LEDs disposed near and behind the upper edge portion of its imaging window, which is provided with an illumination-focusing lens structure integrated therein. During object detection, illumination and imaging operations on the countertop surface, typically at a retail point of sale (POS) station, visible illumination generated by the LEDs is focused and projected by the illumination-focusing lens structure so that the system maintains its illumination rays substantially within the field of view (FOV) of said system, and above which the field of view (FOV) of human operator and spectators are positioned, so that the field of illumination extends substantially across the working distance of the FOV of the system, and in a way to illuminate objects located anywhere within the working distance of said system, while minimizing annoyance to the system operator, as well as others in the vicinity thereof during system operation.

Claims

1. A method of automatically programming system configuration parameters (SCPs) within one or more digital image capture and processing systems, using a communication interface (CI) cable having first and second end portions, and without reading programming-type bar codes, said method comprising the steps of:

(a) providing said one or more digital image capture and processing systems for interfacing with one or more host systems, wherein each said digital image capture and processing system has (i) a SCP/CI programming mode, (ii) a cable connector to receive the first end portion of said CI cable, and (iii) system memory for storing sets of system configuration parameters (SCPs), and also supports a multi-interface detection process, and wherein each said host system interfaced with one said digital image capture and processing subsystem, has a connection port to receive the second end of said CI cable;

(b) during the SCP/CI programming mode of each said digital image capture and processing system, programming (i) a particular set of said SCPs to be associated with (ii) a particular communication interface so as to create multiple sets of SCP/CI parameter settings in the system memory of said digital image capture and processing system;

(c) after the system memory has been programmed with the SCP/CI parameters, deploying one or more of said programmed digital image capture and processing systems within an end-user working environment of an organization or enterprise;

(d) within the end-user working environment of the organization or enterprise, connecting a proper CI cable between (i) the cable connector on each said digital image capture and processing system, and (ii) the connection port on its designated host system, that is to be interfaced with said digital image capture and processing system; and

(e) after said cable has been installed between each said digital image capture and processing system and its designated host system, starting up each said digital image capture and processing system and its designated host system and allowing said multi-interface detection process within said digital image capture and processing system to (i) automatically detect the communication interface supported by its designated host system, and then (ii) automatically implement the detected communication interface by using said programmed SCP/CI parameters associated with the detected communication interface, without the need for reading programming-type bar code symbols.

2. The method of claim 1, which further comprises:

(f) whenever an end-user needs to either (i) swap said digital image capture and processing system from its currently designated host system, to another or new host system within the organization or enterprise, or (ii) replace said digital image capture and processing system with a spare digital image capture and processing system and having the same set of SCP/CI parameters programmed in said system memory, the end-user only needs to establish a communication interface connection between said digital image capture and processing system and its new host system using a proper CI cable, and the communication interface is automatically detected and implemented, and said system configuration parameters (SCPs) are automatically programmed within said digital image capture and processing system so as to support a new host system environment, without reading programming-type bar code symbols.

3. A digital image capture and processing system comprising:

a housing having an imaging window;

an image formation and detection subsystem, disposed in said housing, and having image formation optics for projecting a field of view (FOV) through said imaging window and onto an image detection array, for forming and detecting digital images of an object in said FOV, during object illumination and imaging operations;

an illumination subsystem, disposed in said housing for generating a field of illumination that reflects off an object within said FOV and is transmitted back through said imaging window and onto said image detection array to form one or more digital images of said object;

a computing platform having (i) system memory for storing multiple files for different sets of system configuration parameters (SCPs) associated with different sets of communication interfaces (CI) to provide multiple SCP/CI parameter settings stores in said system memory, and (ii) computing resources for automatically implementing one said set of SCPs when a corresponding communication interface (CI), supported by said digital image capture and processing system and a designated host system to which said digital image capture and processing system is connected by a communication interface (CI) cable, is automatically detected and implemented using a software-controlled interface detection/test process supported by said computing platform.
