摘要： A digital image capture and processing system includes a housing having an imaging window with an illumination-focusing lens structure integrated therewithin. A printed circuit (PC) board is mounted in the housing and has a front surface, a rear surface, and a light transmission aperture spatially aligned with the imaging window. An area-type image detection array is mounted on the rear surface of the PC board. A linear array of light emitting diodes (LEDs) is mounted on the front surface of the PC board, adjacent the light transmission aperture and aligned with the illumination-focusing lens structure. The LEDs produce a plurality of illumination beams which are transmitted through the illumination-focusing lens structure to generate a field of illumination that is projected within the FOV of the system. Illumination reflected and/or scattered off an object within the FOV is retransmitted through the imaging window and the light transmission aperture, and detected by the area-type image detection array.

摘要： A digital image capture and processing system including a housing having an imaging window; and an image formation and detection subsystem with an area-type image detection array having a periodic snap shot mode of the operation supporting the periodic occurrence of snap-shot type image acquisition cycles at a high-repetition rate, during object illumination and imaging operations. The system also includes an illumination subsystem, with a LED illumination array, for producing a field of illumination within the FOV, and illuminating the object detected in the FOV. In the illustrative embodiment, the time duration of illumination of an object within the FOV by the illumination subsystem while the area-type image detection array detects each 2D digital image frame of the object formed on the area-type image detection array, is substantially equal to the time duration that the digital image processing subsystem is allowed to process the detected 2D digital image frame and read a 1D and/or 2D code symbol graphically represented therein.

摘要： A method of capturing processing digital images of an object, using a hand-supportable digital image capture and processing system having a trigger switch, an imaging window and a field of view (FOV) projected therethrough and onto an area-type image detection array. The method involves automatically detecting an object within the FOV, and generating a first trigger event indicative of automatic object detection within the FOV. In response to the generation of the first trigger event signal, the object targeting illumination subsystem automatically generates and projects a visible targeting illumination beam within the FOV. The human operator aligns the visible targeting illumination beam with the object in the FOV, and then manually actuates the trigger switch to generate a second trigger event signal. In response to the generation of the second trigger event signal, a field of illumination is automatically generated and projected through the imaging window and within the FOV, while the targeting illumination beam is momentarily ceased, and 2D digital images of the object are formed and detected on the area-type image detection array, and one or more of the detected 2-D digital images are captured, buffered and processed, so as to read one or more 1D and/or 2D code symbols graphically represented in the one or more detected 2D digital images.

摘要： A method of illuminating objects on a countertop surface using an automatically-triggered digital image capture and processing system having a single array of LEDs disposed near and behind the upper edge portion of its imaging window, which is provided with an illumination-focusing lens structure integrated therein. During object detection, illumination and imaging operations on the countertop surface, typically at a retail point of sale (POS) station, visible illumination generated by the LEDs is focused and projected by the illumination-focusing lens structure so that the system maintains its illumination rays substantially within the field of view (FOV) of said system, and above which the field of view (FOV) of human operator and spectators are positioned, so that the field of illumination extends substantially across the working distance of the FOV of the system, and in a way to illuminate objects located anywhere within the working distance of said system, while minimizing annoyance to the system operator, as well as others in the vicinity thereof during system operation.

摘要： 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.

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.
