Abstract
Within a digital rendering device, such as printers, hard copy and soft copy display, and copiers, rendering parameters of a digital image are perfected as part of an image rendering process using face detection within said rendered image to achieve one or more desired image rendering parameters. Default values are determined of one or more image attributes of at least some portion of the digital image. Values of one or more digital-rendering-device rendering parameters are determined. Groups of pixels are identified that correspond to an image of a face within the digitally-rendered image. Corresponding image attributes to the groups of pixels are determined. One or more default image attribute values are compared with one or more rendered image attribute values based upon analysis of the image of the face. One or more digital-rendering-device rendering parameters are then adjusted corresponding to adjusting the image attribute values.
