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.

What is claimed is: 1. A method of processing a digital image using face detection within said image to achieve one or more desired image processing parameters, comprising: (a) on an apparatus including a processor configured for image processing, acquiring a main digital image and automatically identifying a group of pixels that correspond to an image of a face within the main digital image; (b) generating in-camera, capturing or otherwise obtaining in-camera a collection of low resolution images including said face; (c) tracking said face within said collection of low resolution images; (d) determining default values of one or more parameters of said face within said main digital image based on analysis of said main digital image or on the collection of low resolution images, or both; (e) adjusting values of the one or more parameters within the digital image based upon an analysis of said collection of low resolution images and said digital image including said image of said face and said default values; and (f) rendering, transmitting, transferring, storing, uploading, caching, or displaying said modified image or a further processed version, or combinations thereof. 2. The method of claim 1, wherein the main digital image comprising a digitally-acquired image. 3. The method of claim 1, further comprising processing said main digital image based on said face detection, including receiving a manual or automatic decision. 4. The method of claim 1, wherein the one or more parameters include an orientation of said face. 5. The method of claim 1, wherein the one or more parameters comprise a mask that defines one or more regions where the one or more parameters are valid. 6. The method of claim 5, wherein the mask further comprises a continuous presentation of varying strength within different sub-regions of said one or more regions. 7. The method of claim 5, wherein the one or more parameters comprise identical parameters that differ in value based on the mask. 8. The method of claim 1, further comprising concatenating at least two parameters into a single parameter. 9. The method of claim 1, further comprising selecting one or more parameters manually. 10. The method of claim 1, further comprising transforming said main digital image based on said values of said one or more parameters. 11. The method of claim 1, further comprising creating an operation list for said digital image based on said values of said one or more parameters. 12. The method of claim 11, further comprising embedding said operation list within said main digital image. 13.

The one or more storage devices of claim 21, wherein the one or more parameters comprise a mask that defines one or more regions where the one or more parameters are valid. 26. The one or more storage devices of claim 25, wherein the mask further comprises a continuous presentation of varying strength within different sub-regions of said one or more regions. 27. The one or more storage devices of claim 25, wherein the one or more parameters comprise identical parameters that differ in value based on the mask. 28. The one or more storage devices of claim 21, wherein the method further comprises concatenating at least two parameters into a single parameter. 29. The one or more storage devices of claim 21, wherein the method further comprises selecting one or more parameters manually. 30. The one or more storage devices of claim 21, wherein the method further comprises transforming said main digital image based on said values of said one or more parameters. 31. The one or more storage devices of claim 21, wherein the method further comprises creating an operation list for said digital image based on said values of said one or more parameters. 32. The one or more storage devices of claim 31, wherein the method further comprises embedding said operation list within said main digital image. 33.
