Abstract: A digital image capture and processing system for automatically recognizing objects at a point of sale (POS) station. The system comprising a system housing having an imaging window, and containing a digital image capturing and processing engine including a plurality of coplanar illumination and imaging stations. The stations generate and project a complex of coplanar illumination and imaging planes through the imaging window, and within a 3D imaging volume definable relative to the imaging window for omni-directional imaging of objects passing through the 3D imaging volume, and generate digital linear images of the object as the object intersects coplanar illumination and imaging planes within the 3D imaging volume during system operation. A database is provided for storing one or more object libraries representing objects that can be recognized by the system. A digital image processing subsystem automatically (i) processes digital images generated by said coplanar illumination and imaging stations, (ii) extracts object features from processed digital images, and (iii) recognizes objects which are represented by the object libraries and producing information representative of recognized objects for display at the POS station.

Abstract: A method for intelligently controlling the illumination and imaging of objects while being moved through a 3D imaging volume of a digital image capturing and processing system projecting a plurality of field of views (FOVs) through said 3D imaging volume during system operation. As an object is being moved within the 3D imaging volume, and prior to illumination and imaging, an initial position is determined for the object specifying the beginning of a projected trajectory which the object is likely to follow as the object is moved through the 3D imaging volume. The initial position is used to determine a projected trajectory of the object through the 3D imaging volume. The FOVs which intersect with the projected trajectory of the object, passing through said 3D imaging volume, are determined. Only the determined FOVs are selectively illuminated as the object is moved along its projected trajectory through the FOVs, while digital linear images of the object are formed and detected, for storage and subsequent processing of information graphically represented in the digital linear images.

Abstract: A hand-supportable digital imaging-based bar code symbol reader comprises: an automatic object presence detection subsystem; an image formation and detection subsystem employing a CMOS area-type image detection array; an LED-based illumination subsystem employing an LED illumination array to generate a field of narrow-band LED-based illumination within the FOV; an automatic light exposure measurement and illumination control subsystem employing LED illumination driver circuitry; an image capturing and buffering subsystem; an image-processing bar code symbol reading subsystem; an input/output subsystem; and a system control subsystem for controlling the subsystems. The automatic light exposure measurement and illumination control subsystem controls the LED illumination driver circuitry to expose the automatically detected object, to a field of narrow-band LED-based illumination only when substantially all rows of pixels in the CMOS image sensing array are in a state of integration, thereby enabling the image capturing and buffering subsystem to capture high quality digital images independent of the relative motion between the bar code symbol reader and the object.

Abstract: Method and apparatus for encoding transport stream packets is described. In one example, frames of transport stream packets are block coded to produce block coded symbols. The block coded symbols are interleaved for each of the frames using convolutional interleaving to produce interleaved data. The interleaved data is randomized. The interleaved data is set partitioned for each of the frames into un-coded bits and bits to be encoded. For each of the frames: A low density parity check (LDPC) code is applied to the bits to be encoded to generate a codeword having information bits and parity bits. Groups of interleaved bits are generated from bits in the codeword. Symbols formed from the groups of interleaved bits and the un-coded bits are mapped to points in a quadrature amplitude modulation (QAM) constellation.

Abstract: Methods of and systems for illuminating objects using planar laser illumination beams having substantially-planar spatial distribution characteristics that extend through the field of view (FOV) of image formation and detection modules employed in such systems. Each planar laser illumination beam is produced from a planar laser illumination beam array (PLIA) comprising an plurality of planar laser illumination modules (PLIMs). Each PLIM comprises a visible laser diode (VLD, a focusing lens, and a cylindrical optical element arranged therewith. The individual planar laser illumination beam components produced from each PLIM are optically combined to produce a composite substantially planar laser illumination beam having substantially uniform power density characteristics over the entire spatial extend thereof and thus the working range of the system. Preferably, each planar laser illumination beam component is focused so that the minimum beam width thereof occurs at a point or plane which is the farthest or maximum object distance at which the system is designed to acquire images, thereby compensating for decreases in the power density of the incident planar laser illumination beam due to the fact that the width of the planar laser illumination beam increases in length for increasing object distances away from the imaging optics. By virtue of the present invention, it is now possible to use both VLDs and high-speed CCD-type image detectors in conveyor, hand-held and hold-under type scanning applications alike, enjoying the advantages and benefits that each such technology has to offer, while avoiding the shortcomings and drawbacks hitherto associated therewith.
