摘要:
A digital image capture and processing system capable of illuminating the entire field of view (FOV) of the system using a linear LED-based illumination array. The system includes a housing having an imaging window with a refractive-type illumination-focusing lens component integrated therewithin. The area-type image formation and detection subsystem, also disposed in the housing, has image formation optics for projecting a field of view (FOV) through the imaging window and onto an area-type image detection array, for forming and detecting 2D digital images of an object in the FOV, during object illumination and imaging operations. The linear LED-based illumination array is disposed immediately behind the refractive-type illumination-focusing lens component, for producing a field of wide-area illumination illuminating substantially the entire FOV over the working distance of the system. During object illumination and imaging operations, the illumination reflects off an object within the FOV and is transmitted back through the imaging window and onto the area-type image detection array to form one or more 2D digital images of the object.

A digital image capture and processing system including a housing having an imaging window. An area-type image formation and detection subsystem is disposed in the housing, and has image formation optics for projecting a field of view (FOV) through the imaging window and onto an area-type image detection array, for forming and detecting 2D digital images of an object in the FOV, during object illumination and imaging operations. The housing also includes a multi-mode LED-based illumination subsystem having (i) a near-field LED array for producing a field of wide-area narrow-band illumination over a near field region of said FOV, and (ii) a far-field LED array for producing a field of wide-area narrow-band illumination over a far field region of the FOV. During object illumination and imaging operations, illumination from illumination arrays reflects off the object and is transmitted back through the imaging window and onto the area-type image detection array to form 2D digital images of the object.

A digital image capture and processing system including a housing having an imaging window; and an image formation and detection subsystem supporting a periodic snap shot mode of the operation. The system includes image formation optics for projecting a field of view (FOV) through said imaging window and upon an object within the FOV, and forming an image of the object on an area-type image detection array having a plurality of rows of image detection elements, and detecting 2D digital images of the object while object illumination and imaging operations. The system also includes an LED-based illumination subsystem, with a LED illumination array, for producing a field of narrow-band illumination within the FOV, and illuminating the object detected in the FOV, so that the illumination reflects off the object and is transmitted back through the light transmission aperture and onto the image detection array to form the 2D digital image of the object. During the periodic snap shot mode of the operation, the image detection array supports periodic image acquisition cycles, and during each image acquisition cycle, substantially all image detection elements in the image detection array are exposed simultaneously to the illumination. In the illustrative embodiment, each image acquisition cycle has a predetermined time duration followed by a decode-processing cycle having a time duration approximately equal to the duration of the image acquisition cycle so that at least ten (10) image frames can be acquired per second.

A hand-supportable digital image capture and processing system including a hand-supportable housing having an imaging window, and an area-type image formation and detection subsystem having image formation optics for projecting a field of view (FOV) through the imaging window and an area type image detection array having a snap-shot mode of operation for forming and detecting a 2D digital image of the object during each image acquisition cycle of the image detection array. The system includes a manual trigger switch integrated with the hand-supportable housing, for generating a trigger event, indicative that a code symbol on the detected object is aligned with the visible targeting illumination beam and is ready for illumination and imaging. The system includes an object targeting illumination subsystem for generating and projecting a visible targeting illumination beam within the FOV, in response to the generation of the trigger event signal. The system further includes an LED-based illumination subsystem which is responsive to the second triggering event, for generating and projecting a field of illumination through the imaging window and within the FOV so that light transmitted through the imaging window towards the object is reflected off the object and detected by the area-type image detection array within the hand-supportable housing. An automatic illumination control subsystem controls the operation of the LED-based illumination subsystem during object illumination and imaging operations, so that the targeting illumination beam is momentarily ceased when the LED-based illumination subsystem produces the field of illumination within the FOV.

A hand-supportable digital image capture and processing system including a hand-supportable housing having an imaging window. A printed circuit (PC) board is mounted in the hand-supportable housing, and has front and rear surfaces and a light transmission aperture formed centrally therethrough. An image formation and detection subsystem has image formation optics for projecting a field of view (FOV) through the imaging window and upon an object within the FOV, and an area-type image detection array for forming and detecting 2D digital images of the object during object illumination and imaging operations. A first FOV folding mirror is supported above the rear surface of the PC board over the light transmission aperture, and a second FOV folding mirror is supported above the rear surface of the PC board and over the area-type image detection array. These mirrors fold and project the FOV through the light transmission aperture and the imaging window. An automatic targeting illumination subsystem is disposed in the hand-supportable housing, and has a plurality of visible light sources mounted on the rear surface of the PC board for generating a targeting illumination beam, which reflects off at least one beam folding mirror, and then off the first FOV mirror and then projects the targeting illumination beam through the light transmission aperture and the imaging window, into a portion of said FOV extending outside of the hand-supportable housing and onto the object therein.

An optical code symbol reading system including a hand-supportable housing having a light transmission aperture. A manually-actuated trigger switch is integrated within the housing. An optical code symbol reading subsystem is disposed in the housing for optically reading a code symbol in the field external to the light transmission aperture, and generating symbol character data representative of the read code symbol. One or more light emitting diodes (LEDs) are disposed in the housing, for producing a visible illumination. Also, an optical-waveguide structure is disposed in the housing for coupling visible illumination produced from the one or more LEDs, so as to illuminate the region about the manually-actuated trigger switch, thereby causing the optically-translucent region about the manually-actuated trigger switch to glow and visually indicate where it is located on the hand-supportable housing.

摘要:
A method of illuminating objects on a countertop surface using an automatically-triggered digital image capture and processing system installed thereupon, and having a single array of LEDs disposed behind the upper edge portion of its imaging window, above which a light ray blocking shroud portion is provided. During object detection, illumination and imaging operations above the countertop surface, typically at a retail point of sale (POS) station, visible illumination rays are generated by the LEDs and projected substantially within the field of view (FOV) of the system, while the light ray blocking shroud blocks a portion of illumination rays generated from the single array of LEDs and projected above and beyond the FOV of the system, and thus prevents such blocked illumination rays from striking the eyes of the system operator or nearby consumers during system operation.
