Example methods and apparatus to provide radial aiming patterns are disclosed herein. An example assembly includes an imaging assembly configured to capture an image of a portion of an environment in a field of view (FOV); and an aiming light generator configured to form an illuminated radial aiming pattern and present the illuminated radial aiming pattern to enable the portion of the environment to be positioned within the FOV, the illuminated radial aiming pattern including an illuminated central mark in a central area of the illuminated radial aiming pattern, an illuminated first line, an illuminated second line, an illuminated third line, and an illuminated fourth line, wherein the first line, the second line, the third line, and the fourth line extend outward from the central mark and are angularly distributed about the central mark.

A method and apparatus for directing an aim light through a window of an image reader. The window has a cylindrically curved section. The aim light impinges on a portion of the cylindrically curved section of the window prior to partially passing through the window. A first amount of the aim light is passed through the window, and a second amount of the aim light is reflected into the cavity resulting in reflected aim light. The reflected aim light is directed away from the imaging assembly such that no or substantially no reflected aim light impinges on the imager of the imaging assembly.

Devices and methods for reading picklists are disclosed herein. An example barcode reader device includes an imaging assembly to capture images while scanning over picklist. The barcode reader includes a processing platform configured to decode, for each image, any newly appearing decodable barcode within the image, evaluate, using positional tracking, whether a decodable barcode is within a decode region of a field view, thereby indicating a barcode to decode, and instead of decoding that barcode, access previously stored decoded barcode data for the barcode and report that data, thereby allowing the barcode reader to avoid scanning and decoding the barcode at the decode region, and avoid on-axis reflection errors.

Various embodiments described herein relate to calibration for scanning device decoding based on aimer pattern detection. In this regard, a first image frame captured using a scanning device is decoded. The first image frame is related to an object associated with a barcode. Additionally, a second image frame related to the object associated with the barcode is capture using the scanning device. The second image frame comprises an aimer pattern generated by an aimer of the scanning device. A location of the aimer pattern in the second image frame is determined based on a motion transform correlation between the barcode in the first image frame and the aimer pattern in the second image frame. Additionally, an aiming position of the aimer is calibrated based on the location of the aimer pattern determined by the motion transform correlation.

Near and far imagers image close-in and far-out targets over relatively wider and relatively narrower imaging fields of view, respectively. An aiming assembly directs to a target a visible aiming light pattern having an aiming light spot and a pair of collinear aiming light lines. The aiming light spot is substantially centered between the aiming light lines. A controller determines a distance to the target based on a position of the aiming light spot in the imaging field of view of a default one of the imagers, selects at least one of the imagers based on the determined distance, and enables both the close-in and the far-out targets to be positioned substantially entirely within the respective imaging field of view of the selected imager.

A data capture device includes: a display, a primary image sensor having a primary field of view centered on a primary optical axis; an auxiliary image sensor having an auxiliary field of view centered on an auxiliary optical axis, wherein the auxiliary field of view is larger than the primary field of view; a memory storing offset data defining an offset between the primary field of view and the auxiliary field of view; a data capture controller connected to the primary image sensor, the auxiliary image sensor and the memory; wherein the data capture controller is configured to: responsive to activation of an aiming mode, control the auxiliary image sensor to capture a video stream; select, according to the offset data, a portion of the video stream corresponding to the primary field of view; and present the selected portion of the video stream on the display.

An assisted aimer for rapid, accurate, and low-cost imaging of barcodes, includes a hand-held device, such as a smart phone or tablet, having a digital camera with built-in flash, a specialized software application executing on the phone, and an aimer apparatus attached in front of the flash aperture for forming an aimer beam at a predetermined distance. The aimer beam assists a user in accurately pointing the device at a target barcode. The aimer is attachable directly to the smart phone or camera, or is made a part of an enclosure that accepts the smart phone or tablet into a self-aligning receiving space. Aiming beam assistance enables the camera, its auto-focus, and the installed software application image processing to deliver rapid, snappy, barcode imaging.

An indicia-reading module is capable of integration into the smallest face of thin-profile smart device. The module employs chip-on-board packaging and a customized sensor enclosure to eliminate the stack-up height found in conventional packaging. The module also employs a customized frame to reduce volume by integrating circuit subassembly circuit boards into a unique architecture and by serving as the lenses for the illuminator and the aimer, thereby eliminating the need for any extra lenses or holders.
