Barcode readers and barcode reader assemblies with lift handles are disclosed herein. An example bioptic barcode reader assembly includes a barcode reader having a housing and a metal frame secured to the housing. A retractable first lift handle having an elongated first aperture is positioned on a first side of the housing and a retractable second lift handle having an elongated second aperture is positioned on a second side of the housing, opposite the first side. Each of the first and second lift handles is movable relative to the housing between a retracted position and an extended position and the first and second apertures in the first and second lift handles overlie a first center of gravity of the barcode reader and a second center of gravity of the barcode reader assembly.

Disclosed are an image capturing system and method. In the image capturing system and method, a light path is changed by controlling a reflection angle of a mirror surface using a rotating mirror so that a single camera obtains consecutive images at various angles or at a wide photographing width.

An optical information reader includes an imaging lens and a lens retainer retaining the imaging lens and assembled, in this state, into the holder. The lens retainer includes a flange bottom surface and end faces as a reference surface that is parallel to an optical axis of the imaging lens. The holder includes a top surface and edge faces as a guide surface. The guide surface is brought into surface contact with the flange bottom surface and the end faces when the lens retainer is assembled into the holder, and is brought into slidable contact with the flange bottom surface and the end faces when the lens retainer is moved along the optical axis. Thus, influence of one-sided blur is minimized in terms of variation in resolution which is measured when obtaining an optimal focus position by changing relative positions of the area sensor and the imaging lens.

Systems and methods for user choice of barcode scanning ranges are provided. This is achieved through the identification of a predetermined pixel-per-module threshold range. The pixel-per-module of a barcode being read by a reader is compared to the predetermined pixel-per-module threshold range, and a successful decode of the barcode is carried out only if the pixel-per-module of the barcode falls within the predetermined range. Thus, a user may select a desired reading distance range such that barcodes within a working distance range may not generate successful decodes if such barcodes are outside of the desired reading distance range.

Bioptic barcode readers are disclosed herein. An example bioptic barcode reader includes an upper housing and a lower housing secured directly to the upper housing, the lower housing and the upper housing defining an interior region. The upper housing includes a horizontally extending portion, an integral and unitary tower portion extending above the horizontally extending portion, a generally horizontal window positioned in the horizontally extending portion, and a generally upright window positioned in the tower portion. An imaging sensor, at least one intermediate mirror, at least one vertical output mirror, and at least one horizontal output mirror are positioned within the interior region.

An aiming system for use in a small height scan engine chassis. The aiming system includes a beam source assembly generating an input beam along a central axis and a collimator assembly having a lens group that defines a tilt axis having a tilt angle, α, relative to the central axis, to deflect the input beam from the central axis onto the tilt axis. The collimator assembly further includes a recess within which a diffractive optical element is sealably mounted to convert the deflected input beam into an aiming pattern at a focal distance of the lens group.

An image processing apparatus communicates an image capture device having panning, tilting, and zooming function. A code area is detected by performing a matching process on a whole object image area acquired by photographing an area including a whole predetermined object on which codes are attached, by an image capture device. Grouped areas are generated by grouping detected code areas, based on an angle of view to be set when performing photographing with zooming. The image capture device performs panning, tilting, and zooming operations, such that the generated grouped areas are sequentially photographed at a zoom magnification setting value. An image processing area set with respect to a group image obtained by performing the panning, tilting, and zooming operations and photographing each of the generated grouped area. Information on each code area included in the set image processing area is read.

An accessory for a mobile computing device having a camera with a field of view (FOV), includes: an adapter including: an inner wall having a first opening; a retention mechanism configured to releasably retain the mobile computing device against the inner wall with the camera positioned over the first opening; an outer wall joined to the inner wall by a set of side walls, the outer wall having a second opening with a second perimeter larger than a first perimeter of the first opening; a set of channel walls extending between the first perimeter of the first opening and the second perimeter of the second opening, the set of channel walls defining an open channel permitting the camera FOV to traverse the adapter substantially unobstructed; and a handle mount disposed on the outer wall.

Example methods and apparatuses to mitigate specular reflections and direct illumination interference in bioptic barcode readers are disclosed. An example method includes creating a first sub-field of view passing through a first window, creating a second sub-field of view passing through a second window, while activating a first illumination source to illuminate the first sub-field of view and deactivating a second illumination source associated with the second sub-field of view, capturing first images of the first sub-field of view, while activating the second illumination source to illuminate the second sub-field of view and deactivating the first illumination source, capturing second images of the second sub-field of view, and attempting to decode a barcode within at least one of the first images and the second images.

A machine vision system can include an image sensor assembly including an image sensor, a lens assembly coupled to the image sensor assembly, an illumination assembly coupled to the lens assembly, and a removable front cover positioned in front of the illumination assembly. The illumination assembly can include a plurality of multispectral light assemblies. Each multispectral light assembly of the plurality of multispectral light assemblies can include a multispectral light source having a plurality of color LED dies configured to generate at least two different wavelengths of light, a light pipe positioned in front of the multispectral light source and having an exit surface, a diffusive surface on the exit surface of the light pipe, and a projection lens positioned in front of the diffusive surface. The machine vision system can also include an illumination sensor configured to detect light from the illumination assembly.
