Abstract

A method of processing a digital image using face detection within the image achieves one or more desired image processing parameters. A group of pixels is identified that correspond to an image of a face within the digital image. Default values are determined of one or more parameters of at least some portion of the digital image. Values are adjusted of the one or more parameters within the digitally-detected image based upon an analysis of the digital image including the image of the face and the default values.

Claims

1. A method of processing a digital image using face detection within said image to achieve one or more desired image processing parameters, comprising:

(a) on an apparatus including a processor configured for image processing, acquiring a digital image and automatically identifying a group of pixels that correspond to an image of a face within the digital image;

(b) determining default values of one or more parameters of at least some portion of said digital image;

(c) adjusting values of the one or more parameters within the digitally-detected image based upon an analysis of said digital image including said image of said face and said default values; and

(d) receiving and executing a manual command to remove a false indication of another face within the image based on a manual indication that the apparatus has automatically falsely identified another group of pixels as being a face.
