1. A method of digital image processing using face detection for achieving desired chromatic parameters for a face, comprising using a digital image acquisition device or external image processing device, or a combination thereof, that includes a processor that is programmed to perform the method, wherein the method comprises:

  • identifying a group of pixels that correspond to the face within a digital image;

    identifying one or more sub-groups of pixels that correspond to one or more facial features of the face;

    determining initial chrominance values of one or more chromatic parameters of pixels of the one or more sub-groups of pixels;

    determining at least one initial chromatic parameter based on the initial chrominance values; and

    using a spatial mask to determine varying degrees of adjustment of the initial chrominance values of the one or more chromatic parameters;

    determining adjusted values of the one or more chromatic parameters of the pixels of the one or more sub-groups of pixels, based on at least in part on;

    the spatial mask, and a comparison of the initial chromatic parameter with the desired chromatic parameter.
