1. A method of enhancing an appearance of a face within a digital image, comprising using a processor in:
- acquiring a digital image of a scene including a face, including capturing the image using a lens and an image sensor, or receiving said image following capture by a device that includes a lens and an image sensor, or a combination thereof;
identifying the face within the digital image;
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 non-blemished skin tone portions;
smoothing luminance data of the one or more blemish regions to generate smoothed luminance data;
generating an enhanced image including an enhanced version of the face that has original luminance data of the one or more blemish regions replaced with the smoothed luminance data and combined with original non-blemished skin tone portions; and
displaying, transmitting, communicating or digitally storing or otherwise outputting the enhanced image or a further processed version, or combinations thereof; and
determining certain non-skin tone pixels within one or more sub-regions that do not comprise a threshold skin tone, and removing, replacing, reducing an intensity of, or modifying a color of said certain non-skin tone pixels, 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.

8. 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: -
acquiring a digital image of a scene including a face, including capturing the image using a lens and an image sensor, or receiving said image following capture by a device that includes a lens and an image sensor, or a combination thereof; identifying the face within the digital image; 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 non-blemished skin tone portions; smoothing luminance data of the one or more blemish regions to generate smoothed luminance data; generating an enhanced image including an enhanced version of the face that has original luminance data of the one or more blemish regions replaced with the smoothed luminance data and combined with original non-blemished skin tone portions; and displaying, transmitting, communicating or digitally storing or otherwise outputting the enhanced image or a further processed version, or combinations thereof, and wherein the method further comprises determining certain non-skin tone pixels within the one or more sub-regions that do not comprise a threshold skin tone, and removing, replacing, reducing an intensity of, or modifying a color of said certain non-skin tone pixels, or combinations thereof. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. One or more non-transitory 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:
-
acquiring a digital image of a scene including a face, including capturing the image using a lens and an image sensor, or receiving said image following capture by a device that includes a lens and an image sensor, or a combination thereof; identifying the face within the digital image; 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 non-blemished skin tone portions; smoothing luminance data of the one or more blemish regions to generate smoothed luminance data; generating an enhanced image including an enhanced version of the face that has original luminance data of the one or more blemish regions replaced with the smoothed luminance data and combined with original non-blemished skin tone portions; and displaying, transmitting, communicating or digitally storing or otherwise outputting the enhanced image or a further processed version, or combinations thereof, and wherein the method further comprises determining certain non-skin tone pixels within the one or more sub-regions that do not comprise a threshold skin tone, and removing, replacing, reducing an intensity of, or modifying a color of said certain non-skin tone pixels, or combinations thereof. - View Dependent Claims (16, 17, 18, 19, 20, 21)
