Abstract
An example method of single-exposure multiple-frame image capture, making an HDR video, comprising, capturing a series of frames at an underexposed setting, selecting a reference image from the series of frames, aligning the series of frames to the reference image, merging the series of frames into one frame based on the reference image, indexing the reference image to a next frame in the series of frames, resulting in an indexed reference image, realigning the series of frames to the indexed reference image and remerging the series of frames into a single frame based on the indexed reference image.
Claims5
A method of multiple-exposure multiple-frame image capture, making an HDR video, comprising:
- capturing a first series of frames at a first underexposed setting;
- selecting a first reference image from the first series of frames;
- aligning the first series of frames to the first reference image;
- merging the first series of frames into one first frame based on the first reference image;
- capturing a second series of frames at a second underexposed setting;
- selecting a second reference image from the second series of frames;
- aligning the second series of frames to the second reference image;
- merging the second series of frames into one second frame based on the second reference image;
- and
- fusing the one first frame and the one second frame.
