AUTOMATIC FACE AND SKIN BEAUTIFICATION USING FACE DETECTION
First Claim
Patent Images
1. A method of enhancing an appearance of a face within a digital image, comprising using a processor in:
- generating in-camera, capturing or otherwise obtaining in-camera a collection of one or more relatively low resolution images including a face;
identifying the face within the one or more relatively low resolution images;
segmenting skin tone portions of the face from face features including one or two eyes or a mouth or combinations thereof;
within the skin tone portions of the face, identifying one or more blemish regions that vary in luminance at least a threshold amount from the skin tone portions;
acquiring a main image of higher resolution than the one or more relatively low resolution images, including capturing the main image using a lens and an image sensor, or receiving said main image following capture by a device that includes a lens and an image sensor, or a combination thereof;
smoothing certain original data of one or more regions of the main image that correspond to the same one or more blemish regions identified in the relatively low resolution images to generate smoothed data for those one or more regions of the main image;
generating an enhanced version of the main image including an enhanced version of the face that has the certain original data of the one or more regions corresponding to one or more blemish regions replaced with the smoothed data; and
displaying, transmitting, communicating or digitally storing or otherwise outputting the enhanced image or a further processed version, or combinations thereof.

Abstract
Sub-regions within a face image are identified to be enhanced by applying a localized smoothing kernel to luminance data corresponding to the sub-regions of the face image. An enhanced face image is generated including an enhanced version of the face that includes certain original pixels in combination with pixels corresponding to the one or more enhanced sub-regions of the face.

11. A digital image acquisition device, comprising a lens, an image sensor and a processor, and a processor-readable memory having embodied therein processor-readable code for programming the processor to perform a method of enhancing an appearance of a face within a digital image, wherein the method comprises:
-
generating in-camera, capturing or otherwise obtaining in-camera a collection of one or more relatively low resolution images including a face; identifying the face within the one or more relatively low resolution images; segmenting skin tone portions of the face from face features including one or two eyes or a mouth or combinations thereof; within the skin tone portions of the face, identifying one or more blemish regions that vary in luminance at least a threshold amount from the skin tone portions; acquiring a main image of higher resolution than the one or more relatively low resolution images, including capturing the main image using a lens and an image sensor, or receiving said main image following capture by a device that includes a lens and an image sensor, or a combination thereof; smoothing certain original data of one or more regions of the main image that correspond to the same one or more blemish regions identified in the relatively low resolution images to generate smoothed data for those one or more regions of the main image; generating an enhanced version of the main image including an enhanced version of the face that has the certain original data of the one or more regions corresponding to one or more blemish regions replaced with the smoothed data; and displaying, transmitting, communicating or digitally storing or otherwise outputting the enhanced image or a further processed version, or combinations thereof. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)

21. One or more processor-readable media having embodied therein code for programming one or more processors to perform a method of enhancing an appearance of a face within a digital image, wherein the method comprises:
-
generating in-camera, capturing or otherwise obtaining in-camera a collection of one or more relatively low resolution images including a face; identifying the face within the one or more relatively low resolution images; segmenting skin tone portions of the face from face features including one or two eyes or a mouth or combinations thereof; within the skin tone portions of the face, identifying one or more blemish regions that vary in luminance at least a threshold amount from the skin tone portions; acquiring a main image of higher resolution than the one or more relatively low resolution images, including capturing the main image using a lens and an image sensor, or receiving said main image following capture by a device that includes a lens and an image sensor, or a combination thereof; smoothing certain original data of one or more regions of the main image that correspond to the same one or more blemish regions identified in the relatively low resolution images to generate smoothed data for those one or more regions of the main image; generating an enhanced version of the main image including an enhanced version of the face that has the certain original data of the one or more regions corresponding to one or more blemish regions replaced with the smoothed data; and displaying, transmitting, communicating or digitally storing or otherwise outputting the enhanced image or a further processed version, or combinations thereof. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30)
