Digital image adjustable compression and resolution using face detection information
First Claim
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.

Abstract
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.
