Abstract

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.

Claims (32)

1. Within a digital camera, method of digital image processing using face detection to achieve a desired luminance contrast, comprising the steps of:

(a) identifying a group of pixels that correspond to a face within a digital image;

(b) determining first initial values of luminance of pixels of the group of pixels;

(c) determining second initial values of luminance of pixels other than pixels of the group of pixels;

(d) comparing the first and second initial values to determine an initial luminance contrast; and

(e) determining properties of a fill flash for providing adjusted values of luminance for at least some of the pixels of the digital image based on a comparison of the initial luminance contrast and the desired luminance contrast.

2. The method of claim 1 , the digitally-detected image comprising a digitally-captured image.

3. The method of claim 2 , further comprising the step of automatically providing the determined fill flash.

4. The method of claim 2 , further comprising the step of automatically providing an option for providing a suggested fill-flash.

5. The method of claim 2 , the parameter comprising luminance, the method further comprising the step of automatically generating the adjusted digital image using the adjusted values.

6. The method of claim 2 , the parameter comprising luminance, the method further comprising automatically providing an option to generate the adjusted digital image using the adjusted values.

7. The method of claim 2 , the parameter comprising luminance, the adjusted values of the luminance being provided by a fill flash.

8. The method of claim 2 , the parameter comprising luminance, the adjusted values of the luminance being provided by a digitally-simulated fill flash.

9. The method of claim 1 , the digitally-detected image comprising a digitally-acquired image.

10. The method of claim 9 , further comprising the step of automatically providing a determined fill flash.

11. The method of claim 9 , further comprising the step of automatically providing an option for providing a suggested fill-flash.

12. Within a digital camera, one or more non-transitory 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 digital image processing using face detection for achieving a desired image parameter, the method comprising:

(a) identifying a group of pixels that correspond to a face within a digital image;

(b) determining first initial values of luminance of pixels of the group of pixels;

(c) determining second initial values of luminance of pixels other than pixels of the group of pixels;

(d) comparing the first and second initial values to determine an initial luminance contrast; and

(e) determining properties of a fill flash for providing adjusted values of luminance for at least some of the pixels of the digital image based on a comparison of the initial luminance contrast and the desired luminance contrast.

13. The one or more non-transitory storage devices of claim 12 , the digitally-detected image comprising a digitally-captured image.

14. The one or more non-transitory storage devices of claim 13 , the method further comprising automatically providing the determined fill flash.

15. The one or more non-transitory storage devices of claim 13 , the method further comprising automatically providing an option for providing a suggested fill-flash.

16. The one or more non-transitory storage devices of claim 13 , the parameter comprising luminance, the method further comprising the step of automatically generating the adjusted digital image using the adjusted values.

17. The one or more non-transitory storage devices of claim 13 , the parameter comprising luminance, the method further comprising automatically providing an option to generate the adjusted digital image using the adjusted values.

18. The one or more non-transitory storage devices of claim 13 , the parameter comprising luminance, the adjusted values of the luminance being provided by a fill flash.

19. The one or more non-transitory storage devices of claim 13 , the parameter comprising luminance, the adjusted values of the luminance being provided by a digitally-simulated fill flash.

20. The one or more non-transitory storage devices of claim 12 , the digitally-detected image comprising a digitally-acquired image.

21. The one or more non-transitory storage devices of claim 20 , further comprising the step of automatically providing a determined fill flash.

22. The one or more non-transitory storage devices of claim 20 , further comprising the step of automatically providing an option for providing a suggested fill-flash.
