摘要： A portable digital image capturing and processing system comprising: an image formation and detection subsystem; a narrow-band illumination subsystem; a narrow-band transmission-type optical filter subsystem; an automatic light exposure measurement subsystem; and an automatic illumination control subsystem. The image formation and detection subsystem has an area-type image sensing array for detecting digital images of objects formed thereon by image formation optics providing a field of view (FOV) for the system. Within the FOV of the image formation and detection subsystem, the narrow-band illumination subsystem produces a field of narrow-band illumination consisting essentially of a narrow band of wavelengths of visible illumination. The narrow-band transmission-type optical filter subsystem transmits substantially only the narrow band of wavelengths of visible illumination produced from the narrow-band illumination subsystem, and rejects all other optical wavelengths outside the narrow band however generated by ambient illumination sources. The automatic light exposure measurement subsystem employs a photo-detector operated independently from the area-type image sensing array, for automatically measuring the light exposure incident upon a selected portion of the FOV, and producing an electrical signal representative of the light exposure measurement. Only when all sensor elements in the image-sensing sensing array are activated and in state of integration, then narrow-band illumination is produced for illuminating objects in FOV of the system and simultaneously detected by a photo-detector for measuring light exposure within the FOV, and also by an area-type image sensing array for detecting a digital image of said illuminated object.

摘要： A digital-imaging based code symbol reading system having a hands-on mode operation and a hands-free presentation mode of operation, and supporting automatic programming of system parameters for automatic configuration of the system in hands-on and hands-free modes of operation. The system comprises: an image formation and detection subsystem; an illumination subsystem; a digital image processing subsystem; a system control subsystem for managing system parameters, and controlling and/or coordinating operations of the system; and a configuration detection mechanism. The image formation and detection subsystem has the area-type image sensing array for detecting digital images of objects formed thereon by image formation optics providing a field of view (FOV) for the system. Within the FOV of the image formation and detection subsystem, the illumination subsystem produces a field of illumination that illuminates the object during the image capture mode of operation, and one or more digital images thereof are detected by an area-type image sensing array. When the hand-supportable housing is picked up from on a countertop surface or support stand and held in an operator's hand, the system parameters are automatically programmed so that the digital-imaging code symbol reading system is automatically configured into its hands-on mode of operation. When the hand-supportable is resting on the countertop surface or in the support stand, the system parameters are automatically programmed so that the digital-imaging code symbol reading system is automatically configured into its hands-free presentation mode of operation.

摘要： A method of illuminating objects using adaptively controlled mixing of spectral illumination energy to form and detect digital images of objects at POS environments with sufficiently high image contrast and quality. The method comprises provides, at a POS environment, a digital image capture and processing system having a system housing with an imaging window, and an area-type illumination and imaging station disposed within said system housing, for projecting a coextensive area-type illumination and imaging field (i.e. zone) through said imaging window into a 3D imaging volume during object illumination and imaging operations. As the object is moved through the 3D imaging volume, its motion is automatically detected, and signals indicative of said detected object motion are generated. In response to the generated signals, a first field of visible illumination is produced from an array of visible LEDs, simultaneously with a second field of invisible illumination from a array of infrared (IR) LEDs. These first and second fields of illumination spatially overlap and intermix with each other and are substantially coextensive with the FOV. During object illumination and imaging operations, the relative power ratio (VIS/IR) of these fields of visible illumination and invisible illumination are controlled as one or more digital images of said illuminated object are formed and detected, captured and buffered, and ultimately processed so as to read one or more 1D and/or 2D code symbols graphically represented in the digital images. During object illumination and imaging operations operation, the relative power ratio (VIS/IR) is adaptively controlled to form and detect digital images of objects at POS environments with sufficiently high image contrast and quality.

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.
