1. A barcode reading application for a mobile device, the mobile device being selected from the group consisting of smartphones and tablets and comprising a processor, a display screen, memory and a camera comprising an image sensor array, a camera lens focusing illumination from a camera field of view onto the image sensor array, and an output module coupled to the image sensor array, wherein the image sensor array includes a plurality of pixels and the output module being capable of providing output in both:

  • i) a primary color format wherein each pixel is represented by an intensity of each of three primary colors; and

    ii) a color space format wherein each pixel is represented by an intensity value and a plurality of chromatic values, the barcode reading application comprising executable code stored in the memory that, when executed by the processor;

    performs one of;

    i) confirming that the output module is set to provide output in the color space format; and

    ii) setting the output module to provide output in the color space format;

    causes the camera to capture an image of a barcode within the camera field of view;

    receives the color space format intensity value associated with each pixel; and

    decodes the barcode using the intensity values independently of the chromatic values.
