Patent Images

1. A method of processing, the method comprising:

  • capturing, in an image capture device, a first image of a human, the first image of the human representing wavelengths of light in the ultraviolet spectrum;

    capturing, in the image capture device, simultaneously as the first image of the human, a second image of the human, the second image of the human—

    representing wavelengths of light in the visible spectrum;

    processing, in the image capture device, the second image of the human to identify an area of interest within the second image of the human;

    wherein the area of interest within the second image of the human depicts part of the human'"'"'s skin;

    identifying, in the image capture device, a corresponding area of interest within the first image of the human that represents approximately the same area as the identified area of interest within the second image of the human;

    wherein the corresponding area of interest within the first image of the human depicts approximately the same part of the human'"'"'s skin as the area of interest within the second image of the human;

    determining, in the image capture device, a portion of the corresponding area of interest identified as being human skin by comparing the amount of ultraviolet light in the first image of the human, to a predetermined ultraviolet light threshold based on a reflectivity of chemical filters and physical filter of a topical compound comprising sunscreen or a relative ultraviolet light threshold based on the reflectivity on a portion of the human'"'"'s skin relative to another portion of the human'"'"'s skin and the surrounding environment in the first image of the human;

    representing, in the image capture device, the portion of the corresponding area of interest in the first image of a human in a false color to create a false colored portion of the area of interest;

    overlaying, in the image capture device, the false colored portion of the area of interest on top of the second image to create a composite image; and

    displaying the composite image in the image capture device.
