  • Decoding color barcodes
    Patent number: 11120238
    Abstract: A method of decoding a color barcode involves simultaneously illuminating the color barcode with three light zones in a manner that illuminates each bar of the color barcode with each of the three spatially separated light zones, where the three light zones are each illuminated by a different one of three colors; capturing a monochrome image of light reflected off of the color barcode that includes each of the bars in the barcode illuminated by the three light zones; and for each bar in the color barcode, determining a color of the bar by analysis of the intensity of the light captured in the image of the reflected light intensity in each of the three light zones.

  • DECODING COLOR BARCODES
    Publication number: 20200394374
    Abstract: A method of decoding a color barcode involves simultaneously illuminating the color barcode with three light zones in a manner that illuminates each bar of the color barcode with each of the three spatially separated light zones, where the three light zones are each illuminated by a different one of three colors; capturing a monochrome image of light reflected off of the color barcode that includes each of the bars in the barcode illuminated by the three light zones; and for each bar in the color barcode, determining a color of the bar by analysis of the intensity of the light captured in the image of the reflected light intensity in each of the three light zones.

  • Decoding color barcodes
    Patent number: 10796119
    Abstract: A method of decoding a color barcode involves simultaneously illuminating the color barcode with three light zones in a manner that illuminates each bar of the color barcode with each of the three spatially separated light zones, where the three light zones are each illuminated by a different one of three colors; capturing a monochrome image of light reflected off of the color barcode that includes each of the bars in the barcode illuminated by the three light zones; and for each bar in the color barcode, determining a color of the bar by analysis of the intensity of the light captured in the image of the reflected light intensity in each of the three light zones.
