BARCODE-READING APPLICATION FOR A MOBILE DEVICE WITH A HIGH RESOLUTION COLOR CAMERA

摘要

This patent specification describes an attachment for a mobile device. The attachment may have an attachment feature designed to be attached to a mobile device such as a smartphone, tablet, or smartphone/tablet with a camera. The attachment may also include an optics system and/or an illumination system that cooperates with the camera to facilitate the capture of decodable barcodes. The illumination system may include a targeting illumination system that facilitates proper positioning of the article and/or an exposure illumination system that helps illuminate the article during capture. The optics system may include a lens that modifies the depth of field and/or the size of the field of view of the camera, an aperture that helps define the field of view, a filter that prevents light of undesired wavelengths from reaching the camera, and/or a mirror that redirects the camera's optical pathway.

主权项

1. A barcode reading application for a mobile device, the mobile device being selected from the group consisting of smartphones, tablets, and smartphone/tablets and comprising a processor, a display screen, a memory, and a camera comprising an image sensor array and a camera lens focusing illumination from a camera field of view onto the image sensor array, the barcode reading application comprising executable code stored in the memory that, when executed by the processor:
sets the image sensor array to output the image in a format in which each pixel is represented by an intensity value and a plurality of chromatic values: causes the camera to capture an image of a barcode within the camera field of view; receives the intensity value associated with each pixel; and decodes the barcode using the intensity values independently of the chromatic values.
