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 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.

Abstract: A digital image capturing and processing system comprising a plurality of coplanar illumination and imaging subsystem for producing a plurality of coplanar linear illumination and imaging planes which intersect within a 3D imaging volume defined relative to an imaging window. Each coplanar illumination and imaging subsystem includes a local object motion detection subsystem for detecting the motion of objects moving through the 3D imaging volume, and a local control subsystem for controlling the state of operations within each coplanar illumination and imaging station during system operation. Each coplanar illumination and imaging subsystem has an object detection state and a code symbol reading state of operation, and includes one or more planar illumination modules (PLIMs) for producing at least one substantially planar illumination beam (PLIB), and a linear image detection array having a field of view (FOV) on the linear image detection array and extending in substantially the same plane as the PLIB, to provide a coplanar illumination and imaging plane (PLIB/FOV) that is projected through the 3D imaging volume, for capturing linear (1D) digital images of an object passing therethrough, for subsequent processing and recognition of information graphically represented in the linear digital images. When a local object motion detection subsystem automatically detects the motion of an object passing through at least a portion of the 3D imaging volume, a global control subsystem cooperates with the local control subsystems to manage the state of operation of each coplanar illumination and imaging subsystem, e.g. by driving one or more of coplanar illumination and imaging subsystems into the code symbol reading state of operation.

An object motion detection subsystem for automatically detecting the motion of an object passing through the 3D imaging volume, and generating motion data representative of the detected object motion. Each station includes an illumination subsystem having a linear illumination array including a plurality of light emitting devices for producing a substantially planar illumination beam (PLIB), and (ii) an image formation and detection subsystem including a linear image sensing array having optics providing a field of view (FOV) on the linear image detection array, and extending substantially along the PLIB. Each station produces at least one coplanar illumination and imaging plane (PLIB/FOV) which is projected through the imaging window and into the 3D imaging volume, for capturing linear (1D) digital images of objects moving through the 3D imaging volume. Each station also includes an automatic illumination control subsystem for controlling the production of illumination by the illumination subsystem into the 3D imaging volume, as an object is detected moving within the 3D imaging volume. Within each station, an image capturing and buffering subsystem captures and buffers linear digital images produced from the linear image detection array, and a local control subsystem controls operations within the coplanar illumination and imaging station using control data derived from motion data generated by the object motion detection subsystem.

Abstract: A digital image capturing and processing system comprising a plurality of coplanar illumination and imaging subsystem for producing a plurality of coplanar linear illumination and imaging planes which intersect within a 3D imaging volume defined relative to an imaging window. The system further includes a global object motion detection subsystem for detecting the motion of objects moving through the 3D imaging volume, and a global control subsystem for controlling the state of operations within each coplanar illumination and imaging station during system operation. Each coplanar illumination and imaging subsystem has an object detection state and a code symbol reading state of operation, and includes an array of planar illumination modules (PLIMs) for producing at least one substantially planar illumination beam (PLIB), and a linear image detection array having a field of view (FOV) on the linear image detection array and extending in substantially the same plane as the PLIB, to provide a coplanar illumination and imaging plane (PLIB/FOV) that is projected through the 3D imaging volume, for capturing linear (ID) digital images of an object passing therethrough, for subsequent processing and recognition of information graphically represented in the linear digital images. When the global object motion detection subsystem automatically detects the motion of an object passing through at least a portion of the 3D imaging volume, the global control subsystem manages the state of operation of each coplanar illumination and imaging station, e.g. by driving ore or more of coplanar illumination and imaging subsystems into the code symbol reading state of operation.
