1. A method for re-composing an image, the method comprising:
- continuously acquiring a plurality of images with selectively adjusted exposures by;
as a camera acquires the plurality of images;
calculating an overall exposure for at least one image of the plurality of images;
determining whether a first image, of the at least one image, depicts a face;
in response to determining that the first image, of the at least one image, depicts the face;
identifying, in the first image, of the at least one image, a first region in which the face is depicted;
calculating a face exposure for the first region in the first image;
based, at least in part, on the overall exposure and the face exposure, determining a first adjusted exposure for at least one region of a second image to be acquired;
acquiring a second image, of the plurality of images, using the first adjusted exposure;
identifying, in the acquired second image, a second region which corresponds to the first region depicting the face;
based, at least in part, on the first image and the second image, generating a re-composed image by replacing at least one group of pixels in the first region in the first image with adjusted exposure pixels of the second image; and
displaying the re-composed image on a device display.

Abstract
A method of generating one or more new digital images using an original digitally-acquired image including a selected image feature includes identifying within a digital image acquisition device one or more groups of pixels that correspond to the selected image feature based on information from one or more preview images. A portion of the original image is selected that includes the one or more groups of pixels. The technique includes automatically generating values of pixels of one or more new images based on the selected portion in a manner which includes the selected image feature within the one or more new images.

8. A non-transitory computer-readable storage medium, storing one or more program instructions which, when executed by one or more processors, cause the one or more processors, to perform:
continuously acquiring a plurality of images with selectively adjusted exposures by; as a camera acquires the plurality of images; calculating an overall exposure for at least one image of the plurality of images; determining whether a first image, of the at least one image, depicts a face; in response to determining that the first image, of the at least one image, depicts the face; identifying, in the first image, of the at least one image, a first region in which an face is depicted; calculating a face exposure for the first region in the first image; based, at least in part, on the overall exposure and the face exposure, determining a first adjusted exposure for at least one region of a second image to be acquired; acquiring a second image, of the plurality of images, using the first adjusted exposure; identifying, in the acquired second image, a second region which corresponds to the first region depicting the face; based, at least in part, on the first image and the second image, generating a re-composed image by replacing at least one group of pixels in the first region in the first image with adjusted exposure pixels of the second image; and displaying the re-composed image on a device display. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A digital camera comprising:
-
one or more sensors continuously acquiring a plurality of images with selectively adjusted exposures; one or more memory units storing the plurality of images; and one or more electronic component circuities that cause the performance of; as the one or more sensors acquire the plurality of images; calculating an overall exposure for at least one image of the plurality of images; determining whether a first image, of the at least one image, depicts a face; in response to determining that the first image, of the at least one image, depicts the face; identifying, in the first image, of the at least one image, a first region in which an face is depicted; calculating a face exposure for the first region in the first image; based, at least in part, on the overall exposure and the face exposure, determining a first adjusted exposure for at least one region of a second image to be acquired; acquiring a second image, of the plurality of images, using the first adjusted exposure; identifying, in the acquired second image, a second region which corresponds to the first region depicting the face; based, at least in part, on the first image and the second image, generating a re-composed image by replacing at least one group of pixels in the first region in the first image with adjusted exposure pixels of the second image; and displaying the re-composed image on a device display. - View Dependent Claims (16, 17, 18, 19, 20)
