Abstract
A system and method are provided for barcode scanning for a target barcode comprising: receiving color image values for a captured image of the target barcode from at least one color image sensor; and extracting luminosity values for each pixel of the captured image from the color image values to define greyscale image values corresponding to the color image values. Once the luminosity values are defined, they are provided as greyscale image values to a greyscale barcode decoder for subsequent processing thereof.
