FACE TRACKER AND PARTIAL FACE TRACKER FOR RED-EYE FILTER METHOD AND APPARATUS
First Claim
1. A portable digital image capturing device having no photographic film, comprising:
- a flash for providing illumination during image acquisition;
an optical system including a lens and an image sensor for capturing a main digital image;
a face tracker for identifying one or more face regions within a series of one or more relatively low resolution reference images, and predicting said one or more face regions within the main digital image;
a face analyzer for determining one or more partial face regions within the one or more face regions each including at least one eye; and
a red-eye filter for modifying an area within the main digital image indicative of a red-eye phenomenon based on an analysis of the one or more partial face regions within the one or more face regions identified and predicted by the face tracker.

Abstract
An image acquisition device includes a flash and optical system for capturing digital images. A face tracker identifies face regions within a series of one or more relatively low resolution reference images, and predicts face regions within a main digital image. A face analyzer determines one or more partial face regions within the one or more face regions each including at least one eye. A red-eye filter modifies an area within the main digital image indicative of a red-eye phenomenon based on an analysis of one or more partial face regions within the one or more face regions identified and predicted by the face tracker.

12. A method of capturing and processing within a portable device a digital image including one or more partial face regions not exhibiting any red eye defect, comprising:
-
acquiring a series of one or more relatively low resolution reference images; identifying one or more face regions within the one or more relatively low resolution reference images each including at least one eye; predicting the one or more face regions within a main digital image based on the identifying; capturing the main digital image with a portable device that includes a lens and an image sensor; providing flash illumination during the capturing of the main digital image with the portable device; determining and analyzing one or more partial face regions, each including at least one eye, within the one or more face regions of the digital image, while foregoing within the digital image analysis of at least one other partial face region not including an eye; and modifying an area within the at least one partial face region that is determined to be indicative of a red-eye phenomenon based on said analyzing. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)

21. One or more processor-readable storage devices having code embedded therein for programming a processor to perform a method of capturing and processing within a portable device a digital image including one or more partial face regions not exhibiting any red eye defect, the method comprising:
acquiring a series of one or more relatively low resolution reference images; identifying one or more face regions within the one or more relatively low resolution reference images each including at least one eye; predicting the one or more face regions within a main digital image based on the identifying; capturing the main digital image with a portable device that includes a lens and an image sensor; providing flash illumination during the capturing of the main digital image with the portable device; determining and analyzing one or more partial face regions, each including at least one eye, within the one or more face regions of the digital image, while foregoing within the digital image analysis of at least one other partial face region not including an eye; and modifying an area within the at least one partial face region that is determined to be indicative of a red-eye phenomenon based on said analyzing. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29)
