Claim 5:
6. An electronic device comprising:
a camera module; and
a processor coupled to the camera module, wherein the processor is configured to:
execute an application,
capture a facial image comprising a color palette through the camera module,
extract, from the facial image, a skin area and multiple reference areas corresponding to the color palette,
detect first colorimetric information for the skin area and second colorimetric information for the reference areas, and
determine a skin color of the skin area by comparing the first colorimetric information and the second colorimetric information, wherein the color palette comprises:
a central section which is provided to define the skin area and is configured to be an empty space or a transparent area, and
multiple color sections provided to define the reference areas and arranged to surround the central section, colors in the color sections being arranged according to a rule based on at least one color characteristic indicating brightness pattern and/or tone pattern of the colors in the color sections, wherein the processor is configured to:
determine whether colors in the reference areas of the facial image are arranged identically with the rule based on a comparison between the second colorimetric information for the reference areas and the at least one color characteristic, and either
determine the skin color of the skin area by comparing the first colorimetric information and the second colorimetric information if the colors in the reference areas are arranged identically with the rule, or
request a re-capturing of the facial image if the colors in the reference areas are arranged differently from the rule.
