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.
