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.

The invention 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-camer
The invention 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) gathering information regarding said face from said collection of low resolution images; (e) automatically determining in-camera processing based on the information gathered regarding said face from said collection of low resolution images; (f) generating a processed version of the still image including the face based on the determining; and (g) outputting the in-camera processed version of the still 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, wherein a quality of said in-camera processing is varied 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, wherein said in-camera processing comprises 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 as recited at claim 1, wherein said low resolution images comprise at least one subsampled version of an acquired higher resolution image. 6. 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. 7. 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. 8. 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) gathering information regarding said face from said collection of low resolution images; (e) automatically determining in-camera processing based on the information gathered regarding said face from said collection of low resolution images; (f) automatically providing an option for in-camera processing of the still image including the face based on the determining; and (g) outputting one or both of the digitally-acquired still image and the in-camera processed image including said face to a digital rendering device for viewing, or displaying, printing, storing or transmitting one or both of the digitally-acquired still image and the in-camera processed image, or combinations thereof. 9. A method of providing an option for in-camera processing as recited in claim 8, wherein said option is variable based on a subjective user decision. 10. A method of providing an option for in-camera processing as recited in claim 9, 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. 11. A computer program encoded on a computer readable medium 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) gathering information regarding said face from said collection of low resolution images; (e) automatically determining in-camera processing based on the information gathered regarding said face from said collection of low resolution images; (f) generating a processed version of the still image including the face based on the determining; and (g) outputting the in-camera processed version of the still image including said face to a digital rendering device for viewing. 12. The computer program product of claim 11, the method further comprising implementing said in-camera processing as adjustable image resolution. 13. The computer program of claim 11, said enhanced quality processing varying between a plurality of groups of pixels that correspond to a plurality of faces. 14. The computer program of claim 11, 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. 15. The computer program of claim 11, wherein said low resolution images comprise at least one subsampled version of an acquired higher resolution image. 16. The computer program of claim 11, wherein said collection of low resolution images comprises one or more thumbnail views or a contact sheet or both. 17. The computer program of claim 11, 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. 18. A computer program encoded on computer readable medium 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) gathering information regarding said face from said collection of low resolution images; (e) automatically determining in-camera processing based on the information gathered regarding said face from said collection of low resolution images; (f) automatically providing an option for in-camera processing of the still image including the face based on the determining; and (g) outputting one or both of the digitally-acquired still image and the in-camera processed image including said face to a digital rendering device for viewing, or displaying, printing, storing or transmitting one or both of the digitally-acquired still image and the in-camera processed image, or combinations thereof. 19. The computer program of claim 18, wherein said option is variable based on a subjective user decision. 20. The computer program of claim 19, 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.
