Disclosed is a barcode scanner. The barcode scanner can include a top plate and a first illumination source. The top plate can include a surface. The surface can define a scanning window and a first edge of the top plate. The first illumination source can be located proximate the first edge of the top plate. The first illumination source can be arranged to direct light in a direction of the scanning window. The light can have a strobe sequence.

Bioptic barcode readers with multiple imaging devices are disclosed herein. An example bioptic barcode reader includes a housing with a generally horizontal window and an upright window, a barcode reading device positioned within the housing, a first imaging device positioned within the housing, and a second imaging device positioned within the housing below the first imaging device. The first imaging device has a first field-of-view directed out of the upright window, the second imaging device has a second field-of-view directed out of the upright window, and a first central imaging axis of the first field-of-view intersects a second central imaging axis of the second field-of-view at an intersecting angle that is greater than or equal to 15 degrees and less than or equal to 55 degrees. The second central imaging axis of the second field-of-view extends upward above the generally horizontal window at a second angle that is greater than 0 degrees.

The imaging system includes a rotating element that is configured to rotate about a central axis. A plurality of scanners are fixedly attached with the rotating element. Each scanner has a lens that faces generally towards the central axis, and the scanners are spaced apart from one another around the central axis. The scanners are configured to identify an optically readable machine readable code contained on the medication container. An actuator is operably connected with the rotating element and is configured to rotate the rotating element and the scanners around the central axis from respective e first positions to respective second positions to allow the scanners to image different areas of the medication container in response to a failure of the scanners to identify the machine readable code when the scanners were in the respective first positions.

A distance to a target to be read by image capture over a range of working distances is determined by directing an aiming light spot along an aiming axis to the target, and by capturing a first image of the target containing the aiming light spot, and by capturing a second image of the target without the aiming light spot. Each image is captured in a frame over a field of view having an imaging axis offset from the aiming axis. An image pre-processor compares first image data from the first image with second image data from the second image over a common fractional region of both frames to obtain a position of the aiming light spot in the first image, and determines the distance to the target based on the position of the aiming light spot in the first image.

A source image having a bit depth greater than eight is captured from a moving target. The source image is processed to obtain a plurality of target images each having a bit depth of eight. A memory stores the 8-bit target images. A processor obtains statistical data about the source image, and selects one of the stored 8-bit target images based on the statistical data. A controller efficiently decodes only the selected 8-bit target image.

At least some embodiments of the present invention are directed toward optical arrangements for use in providing illumination light emitted by a barcode reader. In some embodiments, the arrangement includes an illumination source, a lens positioned within the path of the illumination light emitted by the illumination source where the lens is operable to collimate the light and redirect its central axis, and a window positioned within the path of the redirected and collimated light where the window is operable to alter the illumination light such that the resulting illumination light beam has a height-to-width ratio of less than 8 to 25.

A settlement device according to an embodiment includes a first reading unit configured to read a symbol attached to a commodity located in a first reading region, one or a plurality of second reading units configured to read a symbol attached to a commodity located in a second reading region entirely or partially overlapping the first reading region, and a light emitting unit for causing a customer to recognize a position of the first reading unit.

A checkout workstation includes a generally planar platter having a contact region, a generally horizontal window integrated with the platter, a data capture arrangement for capturing through the horizontal window a target associated with a product to identify the product being checked out at the workstation, and a support structure for supporting the platter in a generally horizontal plane on a plurality of bottom supports during product checkout. The bottom supports are asymmetrically mutually arranged about a periphery of the platter to enable the platter to tilt to a tilted plane that is inclined relative to the horizontal plane when a downward force is exerted on the contact region of the platter for cleaning the horizontal window.

Methods of detecting scan avoidance events during decode sessions are disclosed herein. An example method includes during a timeout period at one or more processors of the symbology scanner, identifying and decoding a transaction affecting indicia on an object in one or more images to obtain a transaction affecting payload; during the timeout period at the one or more processors, identifying one or more visual features in the one or more images; and in response to identifying a non-transaction affecting indicia associated with the one or more visual features, and failing to identify or decode the transaction affecting indicia, determining a potential scan avoidance attempt and generating a scan avoidance alarm signal.

A barcode reader has a housing, weigh platter, and off-platter detection assembly including first and second imaging assemblies in communication with a controller. The first imaging assembly has a first imager configured to capture an image of a first lateral edge of the weigh platter. The second imaging assembly has a second imager configured to capture an image of a second lateral edge of the weigh platter. The controller is configured to: identify and locate the first and second lateral edges; receive first and second images from the imagers; allow the weight of an object to be recorded if determined that a footprint of the object does not extend over the first or second lateral edges; and prevent the weight of the object from being recorded and/or providing an alert to a user if determined that the footprint of the object does extend over the first or second lateral edges.
