Abstract
A barcode scanner device for reading a target barcode having a plurality of feature sections in a first color and a plurality of background sections in a second color. The device comprises: a light source for providing incident illumination onto the target barcode during reading of the target barcode, the light source having a plurality of independently selectable color wavelengths; a photodetector for receiving at least a portion of the incident illumination when reflected off the target barcode as reflected illumination, the reflected illumination used by the photodetector to capture a first color image of the target barcode when a first color wavelength is selected as the incident illumination and to capture a second color image of the target barcode when a second color wavelength is selected as the incident illumination.
