Abstract

A technique for generating a digital photograph comprises blending two related images, each sampled according to a different illumination environment. The two related images are blended according to a blend surface function that includes a height discontinuity separating two different blend weight regions. Color consistency between the two related images is achieved by spatial color correction prior to blending. The technique enables a digital camera to generate a strobe image having an appearance of consistent color despite discordant strobe and ambient scene illumination.

First claim

1 .- 15 . (canceled)

16 . An apparatus, comprising:
at least one non-transitory memory; a touch screen; a camera; and one or more processors in communication with the at least one non-transitory memory, the touch screen, and the camera, wherein the one or more processors execute instructions stored in the non-transitory memory to cause the apparatus to:
in response to a detection of user input on a button:
capture, utilizing the camera configured with a first exposure parameter and without a strobe enabled, a first image at a first time,
capture, utilizing the camera configured with a second exposure parameter, a second image at a second time after the first time and without the strobe enabled, and
combine at least a portion of the first image and at least a portion of the second image to generate a first combined image;

display, utilizing the touch screen, the first combined image;
display, utilizing the touch screen, a slider user interface element; and
in response to a detection of user input on the slider user interface element, adjust the first combined image.

17 . The apparatus of claim 16 , wherein the apparatus is configured such that, in response to the detection of the user input on the button: capture, utilizing the camera, a third image and a fourth image.

18 . The apparatus of claim 17 , wherein the apparatus is configured such that the third image is captured after the second time and with the strobe enabled.

19 . The apparatus of claim 17 , wherein the apparatus is configured such that the third image is stored and is accessible for being displayed utilizing the touch screen.

20 . The apparatus of claim 16 , wherein the apparatus is configured such that the first image and the second image are stored and are accessible for being displayed utilizing the touch screen in response to a detection of corresponding user input.

21 . The apparatus of claim 16 , wherein the apparatus is configured such that the first combined image includes a high dynamic range (HDR) image.

22 . The apparatus of claim 16 , wherein the apparatus is configured such that at least a portion of the first combined image is generated based on at least a portion of a third image.

23 . The apparatus of claim 22 , wherein the apparatus is configured such that the at least portion of the third image is generated based on at least a part of the first image and at least a part of the second image.

24 . The apparatus of claim 22 , wherein the apparatus is configured such that the at least portion of the third image is generated based on a blend of at least a part of the first image and at least a part of the second image.

25 . The apparatus of claim 22 , wherein the apparatus is configured such that the at least portion of the third image is generated based on pixel-by-pixel processing of at least a part of the first image and at least a part of the second image.

26 . The apparatus of claim 22 , wherein the apparatus is configured such that at least a portion of the first combined image is generated to include the at least portion of the third image.

27 . A method, comprising:
at an apparatus including a touch screen and a camera:
in response to a detection of user input on a button:
capturing, utilizing the camera configured with a first exposure parameter and without a strobe enabled, a first image at a first time,
capturing, utilizing the camera configured with a second exposure parameter, a second image at a second time after the first time and without the strobe enabled, and
combining at least a portion of the first image and at least a portion of the second image to generate a first combined image;

displaying, utilizing the touch screen, the first combined image;
displaying, utilizing the touch screen, a slider user interface element; and
in response to a detection of user input on the slider user interface element, adjusting the first combined image.
