A method of adjustable spatial and/or temporal compression of an image including a face includes identifying a group of pixels that correspond to a face within a digitally-acquired image. A first compression portion of the image including the group of pixels is determined. A second compression portion of the image other than the group of pixels is also determined. The first compression portion may be automatically compressed with higher-grade compression than the second compression portion to generate a compressed image including the face, or an option to provided the compressed image including the different grade compressions may be provided.

What is claimed is: 1. A method of in-camera processing of a still image including one or more faces as part of an acquisition process, comprising: (a) identifying a group of pixels that correspond to a face within a digitally-acquired still image on a portable camera; (b) generating in-camera, cap
What is claimed is: 1. A method of in-camera processing of a still image including one or more faces as part of an acquisition process, comprising: (a) identifying a group of pixels that correspond to a face within a digitally-acquired still image on a portable camera; (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 a first processing portion of the image including the group of pixels based on the collection of low resolution images; (e) determining a second processing portion of the image other than the group of pixels; and (f) automatically in-camera processing the first processing portion with enhanced quality processing compared with the second processing portion to generate a processed image including the face; and (g) outputting the in-camera processed image including said face to a digital rendering device for viewing. 2. A method of in-camera processing compression as recited in claim 1, further comprising implementing said in-camera processing as adjustable image resolution. 3. A method of in-camera processing as recited in claim 1, said enhanced quality processing varying between a plurality of groups of pixels that correspond to a plurality of faces. 4. A method of in-camera processing as recited in claim 1, said enhanced quality processing comprising a function of one or more parameters including the relative size of the face, location of the face, exposure of the face, or total of faces detected in the image, or combinations thereof. 5. A method of in-camera processing of a still image including one or more faces as part of an acquisition process, comprising: (a) identifying a group of pixels that correspond to a face within a digitally-acquired still image on a portable camera; (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 a first processing portion of the image including the group of pixels based on the collection of low resolution images; (e) determining a second processing portion of the image other than the group of pixels; and (f) automatically providing an option for in-camera processing the first processing portion with enhanced quality processing compared with the second processing portion to generate a processed image including the face; and (g) outputting the in-camera processed image including said face to a digital rendering device for viewing. 6. A method of providing an option for in-camera processing as recited in claim 5, wherein said option is variable based on a subjective user decision. 7. A method of providing an option for in-camera processing as recited in claim 6, further comprising determining said option as a function of one or more parameters including the relative size of the face, location of the face, exposure of the face, or total of faces detected in the image, or combinations thereof. 8. A computer program product encoded on one or more computer readable media for a processor-based portable camera to carry out a method of in-camera processing of a still image including a face as part of an acquisition process, the method comprising: (a) identifying a group of pixels that correspond to a face within a digitally-acquired still image on a portable camera; (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 a first processing of the image including the group of pixels based on the collection of low resolution images; (e) determining a second processing portion of the image other than the group of pixels; (f) automatically in-camera processing the first processing portion with enhanced quality processing compared with the second processing portion to generate a processed image including the face; and (g) outputting the in-camera processed image including said face to a digital rendering device for viewing. 9. The computer program product of claim 8, the method further comprising implementing said in-camera processing as adjustable image resolution. 10. The computer program product of claim 8, said enhanced quality processing varying between a plurality of groups of pixels that correspond to a plurality of faces. 11. The computer program product of claim 8, said enhanced quality processing comprising a function of one or more parameters including the relative size of the face, location of the face, exposure of the face, or total of faces detected in the image, or combinations thereof. 12. A computer program product encoded on one or more computer readable media for a processor-based portable camera to carry out a method of in-camera processing of a still image including a face as part of an acquisition process, the method comprising: (a) identifying a group of pixels that correspond to a face within a digitally-acquired still image on a portable camera; (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 a first processing portion of the image including the group of pixels based on the collection of low resolution images; (e) determining a second processing portion of the image other than the group of pixels; (f) automatically providing an option for in-camera processing the first processing portion with enhanced quality processing compared with the second processing portion to generate a processed image including the face; and (g) outputting the in-camera processed image including said face to a digital rendering device for viewing. 13. The computer program product of claim 12, wherein said option is variable based on a subjective user decision. 14. The computer program product of claim 13, the method further comprising determining said option as a function of one or more parameters including the relative size of the face, location of the face, exposure of the face, or total of faces detected in the image, or combinations thereof. 15. A method of in-camera processing as recited at claim 1, wherein said low resolution images comprise at least one subsampled version of an acquired higher resolution image. 16. The computer program product of claim 8, wherein said low resolution images comprise at least one subsampled version of an acquired higher resolution image. 17. A method of in-camera processing as recited at claim 1, wherein said collection of low resolution images comprises one or more thumbnail views or a contact sheet or both. 18. The computer program product of claim 8, wherein said collection of low resolution images comprises one or more thumbnail views or a contact sheet or both. 19. A method of in-camera processing as recited at claim 1, further comprising displaying in preview said one or more thumbnail views or said contact sheet or said collection of low resolution images including said face, or combinations thereof. 20. The computer program product of claim 8, wherein the method further comprises displaying in preview said one or more thumbnail views or said contact sheet or said collection of low resolution images including said face, or combinations thereof.
