Digital image processing using face detection information
View Patent ↗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.
1. One or more processor readable storage devices having processor readable code embodied thereon, said processor readable code for programming one or more processors to perform a method of processing a main digital image using face detection to achieve a desired image processing parameter, the method comprising:
on an apparatus including a processor configured for image processing, generating in-camera, capturing or otherwise obtaining in-camera a collection of low resolution images including said face;
tracking said face within said collection of low resolution images;
based on said tracking, automatically identifying a group of pixels that correspond to an image of a face within the main digital image;
determining default values of one or more parameters of at least some portion of said main digital image;
adjusting values of the one or more parameters within the main digital image based upon an analysis of one or more images of said collection of low resolution images including said face and said default values, and
automatically providing a fill flash to digitally add exposure to brighten the group of pixels that correspond to said image of said face while not digitally adding exposure to nor otherwise brightening one or more other pixels within the main digital image.
2. The one or more storage devices of claim 1 , wherein the method further comprises receiving and executing a manual command to remove a false indication of another face within the image based on a manual indication that the apparatus has automatically falsely identified another group of pixels as being a face.
3. One or more processor readable storage devices having processor readable code embodied thereon, said processor readable code for programming one or more processors to perform a method of processing a main digital image using face detection to achieve a desired image processing parameter, the method comprising:
on an apparatus including a processor configured for image processing, generating in-camera, capturing or otherwise obtaining in-camera a collection of low resolution images including said face;
tracking said face within said collection of low resolution images;
based on said tracking, automatically identifying a group of pixels that correspond to an image of a face within the main digital image;
determining default values of one or more parameters of at least some portion of said main digital image;
adjusting values of the one or more parameters within the digitally-detected image based upon an analysis of one or more images of said collection of low resolution images including said face and said default values, and
automatically providing an option for providing a suggested fill-flash to digitally add exposure to brighten the group of pixels that correspond to said image of said face while not digitally adding exposure to nor otherwise brightening one or more other pixels within the main digital image.
4. The one or more storage devices of claim 3 , wherein the method further comprises receiving and executing a manual command to remove a false indication of another face within the image based on a manual indication that the apparatus has automatically falsely identified another group of pixels as being a face.
5. A method of processing a main digital image using face detection to achieve a desired image processing parameter, comprising:
on an apparatus including a processor configured for image processing, generating in-camera, capturing or otherwise obtaining in-camera a collection of low resolution images including said face;
tracking said face within said collection of low resolution images;
based on said tracking, automatically identifying a group of pixels that correspond to an image of a face within the main digital image;
determining default values of one or more parameters of at least some portion of said main digital image;
adjusting values of the one or more parameters within the digitally-detected image based upon an analysis of one or more images of said collection of low resolution images including said face and said default values, and
automatically providing a fill flash to digitally add exposure to brighten the group of pixels that correspond to said image of said face while not digitally adding exposure to nor otherwise brightening one or more other pixels within the main digital image.
6. The method of claim 5 , further comprising receiving and executing a manual command to remove a false indication of another face within the image based on a manual indication that the apparatus has automatically falsely identified another group of pixels as being a face.
7. A method of processing a main digital image using face detection to achieve a desired image processing parameter, comprising:
on an apparatus including a processor configured for image processing, generating in-camera, capturing or otherwise obtaining in-camera a collection of low resolution images including said face;
tracking said face within said collection of low resolution images;
based on said tracking, automatically identifying a group of pixels that correspond to an image of a face within the main digital image;
determining default values of one or more parameters of at least some portion of said main digital image;
adjusting values of the one or more parameters within the digitally-detected image based upon an analysis of one or more images of said collection of low resolution images including said face and said default values, and
automatically providing an option for providing a suggested fill-flash to digitally add exposure to brighten the group of pixels that correspond to said image of said face while not digitally adding exposure to nor otherwise brightening one or more other pixels within the main digital image.
8. The method of claim 7 , further comprising receiving and executing a manual command to remove a false indication of another face within the image based on a manual indication that the apparatus has automatically falsely identified another group of pixels as being a face.
9. A portable digital image acquisition device, including a lens and an image sensor for acquiring digital images, a processor, and one or more processor readable storage devices having processor readable code embodied thereon, said processor readable code for programming the processor to perform a method of processing a main digital image using face detection to achieve a desired image processing parameter, the method comprising:
on an apparatus including a processor configured for image processing, generating in-camera, capturing or otherwise obtaining in-camera a collection of low resolution images including said face;
tracking said face within said collection of low resolution images;
based on said tracking, automatically identifying a group of pixels that correspond to an image of a face within the main digital image;
determining default values of one or more parameters of at least some portion of said main digital image;
adjusting values of the one or more parameters within the digitally-detected image based upon an analysis of one or more images of said collection of low resolution images including said face and said default values, and
