Disclosed are barcode scanners and methods for scanning a barcode. The barcode scanners and methods for scanning a barcode may include receiving a raw image from a scanner. Channel information may be extracted from each pixel of the raw image. A composite image may be created using the channel information from each pixel of the raw image. Finally, product information may be extracted from the composite image.

An apparatus includes a programmable logic configured to: convolve a stencil in a non-rotated orientation about a 2D array of pixels of a captured image received as image data from a camera to generate non-rotated stencil data; generate rotated stencil data based on a rotation of the stencil into a rotated orientation; generate, based on the non-rotated and rotated stencil data, a per-pixel density map indicative of a location of a corner of a 2D indicia within the captured image; employ noise filtering and subsampling to generate, based on the per-pixel density map, a per-tile density map indicative of the location of the corner of the 2D indicia within a 2D array of tiles that corresponds to the 2D array of pixels of the captured image; and generate, based on the per-tile density map, 2D indicia metadata indicative of the location of the 2D indicia within the captured image.

Devices having a long-range imaging engine formed of two cameras having different resolution are disclosed herein. An example imaging engine includes a front-end, with the cameras, terminated in a communication interface for coupling to an external host processor that performs image processor. The front-end has a near field image sensor and a far field image sensor, and a normalization processor to receive the respective image data from the sensors and normalize that image data prior to sending to the host processor. Normalization includes adjusting an image size, aspect ratio, or pixel count complying with data rate constraints imposed by the communication interface or the host processor.

An imaging scanner is provided. The image scanner has a housing. The housing contains a mirror, a camera, a transparent window for scanning, a transparent window for viewing positioned above the transparent window for scanning such that anything presented below the transparent window for scanning is visible in the transparent window for viewing. The transparent window for viewing has an electronic display embedded therein. The imaging scanner also includes an image decoder linked to the camera and to the electronic display. The mirror is positioned such that incident light on the mirror from the transparent scanning window will be reflected within the camera's field of view. The camera is configured to scan images presented at the transparent window for scanning. The image decoder is configured to decode the scanned images. The electronic display is configured to display the decoded information on the transparent window for viewing.

An information recording medium according to one embodiment includes a substrate, a first image, and a second image. The first image is provided on the substrate, emits light when irradiated with first excitation light having a first wavelength, and includes phase-modulated first information. The second image is provided on the substrate, emits light when irradiated with second excitation light having a second wavelength different from the first wavelength, and includes phase-modulated second information.

Some embodiments product identifying systems comprising: a scanner control circuit; an imaging system; a display; and a memory storing a product identifier module executed by the control circuit to: detect, through a series of images, a machine-readable identifier pattern; control the display to render the series of images on the display; activate a scan timer having a scan duration; render, on the display, a scan timer graphic overlaid on a subset of the series of images and corresponding to a changing remaining time of the scan duration as the remaining time expires; confirm that the identifier pattern was maintained within a threshold distance of the center of the field of view over at least a threshold read duration of the scan duration; extract identifying information; and obtain a product identifier corresponding to the identifying information and add the product identifier to a virtual shopping cart.

An image capturing apparatus includes an image capturing portion, a controller to perform image processing to obtain a feature value from image data, and a storage device to accumulate the image data. In an image capturing period of capturing an image of the target object by the image capturing portion, the controller transmits a result of the image processing to a data management server while accumulating the captured image data the storage device, while in an image capturing suspension period of not performing image capturing, the controller transmits the image data accumulated in the storage device to the data management server.

A barcode reader includes: a reading unit that reads a barcode; a decoder that decodes the barcode read by the reading unit so as to obtain barcode information; a determination unit that determines whether the barcode information obtained by the decoder matches barcode information stored in a storage; and a changing unit that changes a reading condition of the reading unit or a decoding condition of the decoder when a result of the determination performed by the determination unit is match.

Disclosed are techniques to enhance an in-counter sweep-style data reader, having frame buffer memory and an imager defining a read zone, so as to improve a likelihood of decoding an optical code appearing in initial image frames by managing utilization of the frame buffer memory according to a prioritization of different categories of image frames captured by the imager as an object bearing an optical code is passed through the read zone.
