Abstract: A barcode reader includes an illumination assembly configured to illuminate a target; an imaging assembly configured to capture an image of the target, and a visual indicator assembly that includes: a projection lens; a first light source configured to emit first color light through the projection lens to project an aim pattern onto the target; a second light source configured to emit second color light through the projection lens to project a visual indicator onto the target; and an optical element configured to direct the light from both the first light source and the second light source to the projection lens. A memory and a processor of the barcode reader are configured to cause the first light source to emit light prior to the imaging assembly capturing the image; and cause the second light source to emit light subsequent to the processor successfully decoding a symbology in the captured image.

Abstract: A method is disclosed for adjusting imaging parameters of a bioptic barcode reader. The method includes capturing, by an imaging assembly, an initial image of a target object having an indicia thereon. The imaging assembly captures the initial image according to an initial imaging parameter. The method further includes attempting to decode the indicia from the initial image, and responsive to being unable to decode the indicia, detecting a substantially static presence of the target object within a field of view (FOV) of the imaging assembly. The method then includes, responsive to detecting the substantially static presence of the target object within the FOV, adjusting the initial imaging parameter to a subsequent imaging parameter, wherein the subsequent imaging parameter is different than the initial imaging parameter.

The imaging reader may include a distance determining module configured to determine a distance to a target. The imaging reader may include an indication determining module configured to determine an out-of-range indication when the distance satisfies a first condition. An indicator may be included and configured to present the out-of-range indication. The image sensor may be configured to capture a representation of an image of the target when the distance satisfies a second condition. The imaging reader may include an indicia decoder configured to decode an indicia in the representation to determine an indicia payload and/or a communication interface to convey the indicia payload to a host system.

Abstract: Methods and systems to implement a miniature long range imaging engine with auto-focus, auto-zoom, and auto-illumination are disclosed herein. An example method includes detecting, by a microprocessor, a presence of an aim light pattern within the FOV; determining, by the microprocessor and in response to the detecting, a target distance of an object in the FOV based on a position of the aim light pattern in the FOV, the target distance being a distance from the imaging engine to the object; causing, by the microprocessor, a variable focus optical element to focus on the object based on the target distance; responsive to making a first determination, by the microprocessor, selecting, based on the target distance, one of a plurality of zoom operation modes; and responsive to making a second determination, by the microprocessor, selecting, based on the target distance, one of a plurality of illumination modes.

Abstract: Barcode readers with transflective mirrors are disclosed herein. An example barcode reader includes a housing and a window positioned within the housing, an imaging sensor and second imaging sensor positioned within the housing, and a transflective mirror positioned within the housing and in a path of a field-of-view of the imaging sensor. The field-of-view of the imaging sensor passes through the transflective mirror and out the window with the transflective mirror in a transmissive state and the field-of-view of the second imaging sensor is reflected off of the transflective mirror and out the window with the transflective mirror in a reflective state.

Abstract: Methods and systems for tracking focus of an adjustable variable focus lens-based imaging system are disclosed. An example method includes identifying an initial focus position of an adjustable variable focus lens assembly and determining focusing parameters corresponding to that focus position. The focusing parameters are compared to a lens behavior model and a new, compensated focus position of the lens assembly is determined correcting for changes in lens assembly performance. A small window focusing sweep range, between forward and aft positions, may also be adjusted based on the lens behavior model to better identify the compensated focus position.

Abstract: Imaging devices, systems, and methods for capturing image data for an object appearing in a field of view (FOV) are described herein. An example device includes: an imaging assembly; an aiming assembly; and a computer-readable media storing machine readable instructions that cause the imaging device to: (i) initiate a first aiming state responsive to receiving an indication of a trigger event; (ii) capture the image data of the object appearing in the FOV while operating in the first aiming state; (iii) transition from the first aiming state to a second aiming state responsive to a successful decode event associated with the indicia, wherein the light source is to emit light in the second aiming state such that an observable appearance is different in the second aiming state than in the first aiming state; and (iv) otherwise refrain from transitioning from the first aiming state to the second aiming state.

Abstract: Methods and apparatus for configuring reduced decode ranges for barcode scanners are disclosed. An example method includes determining a closest focus distance of a plurality of focus distances at which a barcode placed at a furthest limit of a reduced decode range can be successfully decoded; determining a furthest focus distance of the plurality of focus distances at which the barcode placed at a closest limit of the reduced decode range can be successfully decoded; determining a subset of the plurality of focus distances that consists of the closest focus distance, the furthest focus distance, and focus distances between the closest focus distance and the farthest focus distance; and configuring the barcode scanner to only use the subset of focus distances during subsequent attempts to decode barcodes.
