Modification of viewing parameters for digital images using face detection information

摘要

A method of modifying the viewing parameters of digital images using face detection for achieving a desired spatial parameters based on one or more sub-groups of pixels that correspond to one or more facial features of the face. Such methods may be used for animating still images, automating and streamlining application such as the creation of slide shows and screen savers of images containing faces.

1. A method of generating one or more new digital images using an original digitally-acquired image including a face, comprising:
using a processor in
acquiring with an image sensor an original image including the face;identifying one or more groups of pixels that correspond to two or more faces within the original image, including comparing one or more detected luminances and at least one facial orientation within a face identified within a first group of pixels with one or more expected luminances and at least one expected facial orientation of digital facial images, respectively, and identifying a second group of pixels that correspond to another face within the original image;matching one or both of the first and second group of pixels with stored data to uniquely identify at least one of the two of more faces as a specific person or persons, including applying face recognition to the face or faces by comparing the face or faces with stored face image data identified with said specific person or persons;generating a luminance map of the original image including the one or more groups of pixels;selecting a portion of the original image to include the first and second groups of pixels based on the luminance map or on the comparing or both; andautomatically generating values of pixels of one or more new images based on the selected portion in a manner which includes at least one of the two or more faces within the one or more new imageswherein the automatically generating values of pixels of one or more new images comprises applying an automatic fill-flash to, or otherwise adjusting luminance of, one or more of the identified faces based on analysis of the luminance map or on the comparing or both, including brightening one or more of the identified faces relative to background pixels of the one or more new images; andwherein the automatically generating values of pixels of one or more new images further comprises adjusting a relative rotational orientation of one or more faces of the two or more faces within the original image, wherein the adjusting the relative rotational orientation of the one or more faces comprises rotating the one or more faces relative to other portions of the image.
