An encoded information reading (EIR) terminal can comprise a microprocessor communicatively coupled to a system bus, a memory, a communication interface, and a pluggable imaging assembly identified by a type identifier and configured to acquire an image comprising decodable indicia. The imaging assembly can comprise a two-dimensional image sensor configured to output an analog signal representative of the light reflected by an object located within the field of view of the imaging assembly. The EIR terminal can be configured to output, by processing the analog signal, the raw image data derived from the analog signal and/or a decoded message corresponding to the decodable indicia. The imaging assembly can be communicatively coupled to the system bus via an imaging assembly interface comprising a plurality of wires and a multi-pin connector. The imaging assembly interface can comprise one or more wires configured to carry the imaging assembly type identifier. The EIR terminal can be configured, responsive to receiving the type identifier via the one or more wires, to retrieve from the memory one or more imaging assembly configuration information items corresponding to the type identifier and/or to receive via the communication interface one or more imaging assembly configuration information items corresponding to the type identifier. The EIR terminal can be further configured to control the imaging assembly using the imaging assembly configuration information items.

摘要:
A digital illumination and imaging system employing one or more planar laser illumination modules (PLIMs) each including: (i) a laser illumination source driven preferably by high frequency modulated (HFM) diode current drive circuitry; (ii) a beam collimating optics disposed beyond the laser source; (ii) an optical beam multiplexer (OMUX) device disposed beyond the collimating optics; and (iv) a planarizing-type illumination lens array disposed beyond the OMUX device, and arranged for generating a plurality of substantially planar coherence-reduced laser illumination beams (PLIBs) that form a composite substantially planar laser illumination beam (PLIB) having substantially reduced spatial/temporal coherence. A digital image detection array for detecting digital images of an object illuminated by the composite substantially planar laser illumination beam. By virtue of the present invention, the power of speckle pattern noise, observed in a digital image of an object detected at the digital image detection array, is substantially reduced when the digital image is formed using the substantially planar laser illumination beam.
摘要:
A digital image capture and processing system comprising an illumination measurement subsystem for measuring the level of illumination at a particular region of the field of view (FOV) of the system during object illumination and imaging operations, and producing and storing an illumination measure for achieving a desired spatial intensity in a digital image to be formed and detected by the image formation and detection subsystem. An illumination control subsystem uses the illumination measure to control a LED-based illumination array during object illumination and imaging operations. A programmed image processor supports an image-processing based illumination metering program, as well as processes digital images formed and detected by the image formation and detection subsystem so as to read or acquire information graphically represented in the digital images. A computing platform supports the implementation of one or more of the subsystems above, and includes memory for storing at least one code symbol reading application.
摘要:
A hand-supportable digital-imaging based system for reading bar code symbols involving: automatically detecting the presence of an object within a field of view FOV of the system, and in response thereto, automatically generating an image cropping zone (ICZ) framing pattern and projecting the ICZ framing pattern within the FOV and onto the detected object; visually aligning the code symbol on the detected object, within the ICZ framing pattern; manually actuating a trigger switch when the code symbol on the object is located within the ICZ framing pattern, and while the ICZ framing pattern and a field of illumination are being simultaneously projected onto the object during object illumination operations, forming and capturing a digital image of the code symbol on the detected object; automatically cropping the image pixels contained within the spatial boundaries of the ICZ framing pattern, from the pixels of the digital image; and decode processing the cropped image so as to read one or more 1D and/or 2D code symbols graphically represented therein.
