Viewfinder display based on metering images
First Claim
Patent Images
1. A method comprising:
- capturing, by an image capture device, a series of images, wherein the series of images comprises a plurality of metering images interleaved with a plurality of preview images, and wherein the preview images are captured using respective total exposure times (TETs) that are based on characteristics of at least one previously-captured metering image;
displaying, by a viewfinder of the image capture device, a stream of display images, wherein each display image in the stream of display images is derived from at least one of the preview images, and wherein at least part of the capturing of the series of images occurs contemporaneously with at least part of the displaying;
detecting that a shutter function of the image capture device has been triggered;
capturing a second series of images, wherein images in the second series are captured using respective TETs that are based on characteristics of at least one previously-captured metering image; and
storing an output image that is based on at least one of the images in the second series.

Abstract
An image capture device may capture a series of images. The series of images may include a plurality of metering images interleaved with a plurality of preview images. The preview images may be captured using respective total exposure times (TETs) that are based on characteristics of at least one previously-captured metering image. A viewfinder of the image capture device may display a stream of display images. Each display image in the stream of display images may be derived from at least one of the preview images, and at least part of the capturing may occur contemporaneously with at least part of the displaying.

7. An article of manufacture including a non-transitory computer-readable medium, having stored thereon program instructions that, upon execution by a computing device, cause the computing device to perform operations comprising:
-
capturing a series of images, wherein the series of images comprises a plurality of metering images interleaved with a plurality of preview images, and wherein the preview images are captured using respective total exposure times (TETs) that are based on characteristics of at least one previously-captured metering image; displaying a stream of display images, wherein each display image in the stream of display images is derived from at least one of the preview images, and wherein at least part of the capturing occurs contemporaneously with at least part of the displaying; detecting that a shutter function of the computing device has been triggered; capturing a second series of images, wherein images in the second series are captured using respective TETs that are based on characteristics of at least one previously-captured metering image; and storing an output image that is based on at least one of the images in the second series. - View Dependent Claims (8, 9, 10, 11, 12)

13. A method comprising:
-
capturing, by an image capture device, a first metering image and a first set of one or more preview images, wherein the first set of preview images are captured using respective total exposure times (TETs) that are based on characteristics of the first metering image; capturing, by the image capture device, a second metering image and a second set of one or more preview images, wherein the second set of preview images are captured using respective TETs that are based on characteristics of the second metering image; and displaying, by a viewfinder of the image capture device, a display image, wherein the display image is derived from at least one of the first set of preview images, and wherein at least part of capturing the second metering image and the second set of preview images occurs contemporaneously with at least part of the displaying. - View Dependent Claims (14, 15)
