Abstract
Methods, devices, and computer program products for capturing images with reduced blurriness in low light conditions are contained herein. In one aspect, a method of capturing an image is disclosed. The method includes capturing a plurality of first images with a first exposure length. The method further includes aligning each of the plurality of first images with each other and combining the aligned plurality of first images into a combined first image. The method further includes capturing a second image with a second exposure length, wherein the second exposure length is longer than the first exposure length and using the second image to adjust the brightness of the combined first image.
Claims20
A method of capturing an image, the method comprising:
- capturing a plurality of first frames with a first exposure length using an image sensor and storing the plurality of first frames on a memory component;
- processing the captured plurality of first frames to align each of the plurality of first frames with each other;
- combining the aligned plurality of first frames into a combined first image;
- capturing a second image with the second exposure length using an image sensor and storing the second image on the memory component, wherein the second exposure length is longer than the first exposure length;
- and
- using the second image to adjust the brightness of the combined first image.
A device for capturing an image, the device comprising:
- an image sensor configured to capture a plurality of first frames with a first exposure length and store the plurality of first frames on a memory component;
- a processor configured to:
- process the captured plurality of first frames to align each of the plurality of first frames with each other;
- combine the aligned plurality of first frames into a combined first image;
- capture a second image with a second exposure length using the image sensor and storing the second image on the memory component, wherein the second exposure length is longer than the first exposure length;
- and
- use the second image to adjust the brightness of the combined first image.
A device for capturing an image, the device comprising:
- means for capturing a plurality of first frames with a first exposure length using an image sensor and storing the plurality of first frames on a memory component;
- means for processing the captured plurality of first frames to align each of the plurality of first frames with each other;
- means for combining the aligned plurality of first frames into a combined first image;
- means for capturing a second image with the second exposure length using an image sensor and storing the second image on the memory component, wherein the second exposure length is longer than the first exposure length;
- and
- means for using the second image to adjust the brightness of the combined first image.
