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.
Claims20
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.

- (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.
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.
