Digital image processing using face detection information
First Claim
Patent Images
1. A method involving face detection within an acquired digital image, the method comprising:
- using an apparatus including a processor configured for image processing;
acquiring a main digital image with the apparatus and automatically identifying a group of pixels that correspond to an image of a face within the main digital image;
generating in-camera, capturing or otherwise obtaining in-camera a collection of low resolution images including said face;
tracking said face within said collection of low resolution images;
determining default values of one or more parameters of said face within said main digital image based on analysis of said collection of low resolution images;
extracting actual values of said one or more parameters of said face within said main digital image based on analysis of said collection of low resolution images; and
analyzing differences between the default values and actual values of the one or more parameters based on said analysis of said collection of low resolution images; and
determining a further action based on the analyzing of said differences.

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.
