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.
Claims12
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.
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.
