1. Within a digital rendering device, a method of perfecting rendering parameters of a digital image as part of an image rendering process using face detection within said rendered image to achieve one or more desired image rendering parameters, comprising: (a) determining default values of one or more image attributes of at least some portion of said digital image; (b) determining the values of one or more digital-rendering-device rendering parameters; (c) identifying a plurality of groups of pixels that correspond to an image of a face within the digitally-rendered image, and determining corresponding image attributes to said groups of pixels; (d) comparing one or more default image attribute values with one or more rendered image attribute value based upon analysis of said image of said face; and (e) adjusting said digital-rendering-device rendering parameters corresponding to adjusting said image attribute values.
