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.

A method of digital image processing using face detection to achieve a desired image parameter, comprising the steps of: (a) identifying a group of pixels that correspond to an image of a face within a digitally-detected image;(b) determining initial values of one or more parameters of at least s
1. A method of digital image processing using face detection to achieve a desired image parameter, comprising the steps of: (a) identifying a group of pixels that correspond to an image of a face within a digitally-detected image;(b) determining initial values of one or more parameters of at least some of the pixels; and(c) determining an initial parameter of the digitally-detected image based on the initial values; and(d) automatically adjusting or providing an option to adjust values of the one or more parameters of at least pixels within the digitally-detected image that are outside the face, based upon comparison of the initial parameter with the desired parameter. 2. The method of claim 1, the digitally-detected image comprising a digitally-acquired image and the initial parameter of the digitally-detected image comprising an initial parameter of the face image. 3. The method of claim 2, the one or more parameters including orientation, color, tone, size, luminance, relative exposure relative to the exposure of the face, spatial location relative to the face, tone reproduction, sharpness, or focus, or combinations thereof. 4. The method of claim 2, the method being performed within a digital camera. 5. The method of claim 1, the digitally-detected image comprising a digitally-captured image and the initial parameter of the digitally-detected image comprising an initial parameter of the face image. 6. The method of claim 5, the one or more parameters including orientation, color, tone, size, luminance, exposure relative to the exposure of the face, spatial location relative to the face, tone reproduction, sharpness, or focus, or combinations thereof. 7. The method of claim 5, the method being performed within a digital camera. 8. One or more non-transitory processor readable storage devices having processor readable code embodied thereon, said processor readable code for programming one or more processors to perform a method of digital image processing using face detection to achieve a desired image parameter, comprising the steps of: (a) identifying a group of pixels that correspond to an image of a face within a digitally-detected image;(b) determining initial values of one or more parameters of at least some of the pixels; and(c) determining an initial parameter of the digitally-detected image based on the initial values; and(d) automatically adjusting or providing an option to adjust values of the one or more parameters of at least pixels within the digitally-detected image that are outside the face, based upon comparison of the initial parameter with the desired parameter. 9.

The one or more non-transitory storage devices of claim 12, the method being performed within a digital camera. 15. A digital camera, comprising: a lens and an image sensor for capturing digital images;one or more processors; andone or more processor readable storage devices having processor readable code embodied thereon, said processor readable code for programming the one or more processors to perform a method of digital image processing using face detection to achieve a desired image parameter for said digital images, the method comprising: (a) identifying a group of pixels that correspond to an image of a face within a digitally-detected image;(b) determining initial values of one or more parameters of at least some of the pixels; and(c) determining an initial parameter of the digitally-detected image based on the initial values; and(d) automatically adjusting or providing an option to adjust values of the one or more parameters of at least pixels within the digitally-detected image that are outside the face, based upon comparison of the initial parameter with the desired parameter. 16. The digital camera of claim 15, the digitally-detected image comprising a digitally-acquired image and the initial parameter of the digitally-detected image comprising an initial parameter of the face image. 17. The digital camera of claim 16, the one or more parameters including orientation, color, tone, size, luminance, exposure relative to the exposure of the face, spatial location relative to the face, tone reproduction, sharpness, or focus, or combinations thereof. 18. The digital camera of claim 16, the method being performed within a digital camera. 19. The digital camera of claim 16, the digitally-detected image comprising a digitally-captured image and the initial parameter of the digitally-detected image comprising an initial parameter of the face image. 20. The digital camera of claim 19, the one or more parameters including orientation, color, tone, size, luminance, exposure relative to the exposure of the face, spatial location relative to the face, tone reproduction, sharpness, or focus, or combinations thereof. 21. The method of claim 1, wherein the digitally-detected image comprises digitally detected electromagnetic waves but is not stored or saved in a storage unit. 22. The one or more non-transitory storage devices of claim 8, wherein the digitally-detected image comprises digitally detected electromagnetic waves but is not stored or saved in a storage unit. 23. The digital camera of claim 15, wherein the digitally-detected image comprises digitally detected electromagnetic waves but is not stored or saved in a storage unit.
