1. A method of digital image processing using face detection for achieving desired chromatic and luminance 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 a face within a digital image; identifying one or more sub-groups of pixels that correspond to one or more facial features of the face including at least one sub-group of pixels that substantially comprise one or two eyes, a mouth, a chin or a nose, or combinations thereof; determining initial chrominance values of one or more chromatic parameters of pixels of the one or more sub-groups of pixels including said at least one sub-group of pixels that substantially comprise one or two eyes, a mouth, a chin or a nose, or combinations thereof; determining initial luminance values of one or more luminance parameters of said pixels of the one or more sub-groups of pixels that substantially comprise one or two eyes, a mouth, a chin or a nose, or combinations thereof; determining at least one initial chromatic parameter based on the initial chrominance values; determining at least one initial luminance parameter based on the initial luminance values; determining adjusted values of the one or more chromatic parameters of the pixels of the one or more sub-groups of pixels, including said at least one sub-group of pixels that substantially comprise one or two eyes, a mouth, a chin or a nose, or combinations thereof, based on a comparison of the initial chromatic parameter with the desired chromatic parameter; and determining adjusted values of the one or more luminance parameters of the pixels of the one or more sub-groups of pixels, including said at least one sub-group of pixels that substantially comprise one or two eyes, a mouth, a chin or a nose, or combinations thereof, based on a comparison of the initial luminance parameter with the desired luminance parameter.
