  • Patent number: 7594609
    Abstract: An automatic digital video image capture and processing system supporting image-processing based code symbol reading during a pass-through mode of system operation at a retail point of sale (POS) station. The system comprises an automatic object direction detection subsystem, disposed in its housing, as well as an illumination subsystem, an image formation and detection subsystem, an automatic illumination control subsystem, a digital image capturing and buffering subsystem, a digital image processing subsystem, and a system control subsystem. During system operation, the automatic object direction detection subsystem automatically detects the presence and direction of movement of the object in the field of view (FOV), and in response thereto, generates a first signal indicating a triggering event and a second signal indicating the direction of movement of the object with respect to the FOV.

  • Patent number: 7594608
    Abstract: An automatic omni-directional bar code symbol reading system for use in a POS environment. The system comprises a system housing having an light transmission window. A plurality of linear-type bar code symbol reading stations are disposed in the system housing, for generating and projecting a complex of linear illumination planes through the light transmission window and into a 3D volume definable relative to the system housing. At least one area-type bar code reading station is disposed in the system housing, for generating and projecting an area illumination beam through the light transmission window and into the 3D volume. The complex of linear illumination planes and the area illumination beam enable omni-directional reading of bar code symbols on an object passing through the 3D volume, and the generation symbol character data representative of the read bar code symbol.

  • Patent number: 7588188
    Abstract: A digital image capturing and processing system including an image formation and detection (IFD) subsystem having a linear image sensing array and optics providing a field of view (FOV) on the linear image sensing array. A spectral-mixing based illumination subsystem produces a first field of visible laser illumination produced from an array of visible VLDs, and a second field of invisible laser illumination produced from an array of IR laser diodes (LDs) that spatially overlap and intermix with each other so as to produce a composite planar laser illumination beam which is substantially with the FOV of the linear image sensing array. An illumination control subsystem controls the spectral mixing of visible and invisible laser illumination produced from the spectral-mixing based illumination subsystem, by adaptively controlling the relative power ratio (VIS/IR) of said fields of visible and invisible laser illumination.

  • Patent number: 7578442
    Abstract: A method of and system for identifying a consumer product in a retail store environment when a bar code symbol on a product is not readable or has been removed from the product's packaging. The system comprises a database system, and a digital image capturing and processing system installed in the retail environment and in data communication with the database system. The digital image capturing and processing system is capable of capturing one or more digital images for each consumer product sold in the retail store environment, and storing the digital images in the database subsystem, along with product identifying information for each consumer product. When the imaged bar code symbol happens to be unreadable, or when the bar code symbol label happens to have fallen off or have been removed from the packaging, then one or more digital images of the consumer product are compared with digital images stored in the database subsystem to identify the consumer product graphically represented in the digital images.

  • Patent number: 7575170
    Abstract: 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 providing, at a POS environment, a digital image capture and processing system having a system housing with an imaging window, and a coplanar illumination and imaging station disposed within said system housing, for projecting a coplanar illumination and imaging plane through the imaging window into an imaging volume during object illumination and imaging operations. As the object is moved through the imaging volume, its motion is automatically detected, and signals indicative of said detected object are generated. In response to the generated signals, a first field of visible illumination is produced from an array of visible laser diodes (VLDs), simultaneously with a second field of invisible illumination from a array of infrared (IR) laser diodes (LDs).
