Abstract

A method of producing a stereo image from a digital video includes receiving a digital video including a plurality of digital images captured by an image capture device; and using a processor to produce stereo suitability scores for at least two digital images from the plurality of digital images. The method further includes selecting a stereo candidate image based on the stereo suitability scores; producing a stereo image from the selected stereo candidate image wherein the stereo image includes the stereo candidate image and an associated stereo companion image based on the plurality of digital images from the digital video; and storing the stereo image whereby the stereo image can be presented for viewing by a user.

First claim

The invention claimed is:

1. A method of producing a stereo image from a digital video, comprising:
(a) receiving a digital video including a plurality of digital images captured by an image capture device;
(b) using a processor to produce stereo suitability scores for at least two digital images from the plurality of digital images;
(c) selecting a stereo candidate image based on the stereo suitability scores;
(d) producing a stereo image from the selected stereo candidate image wherein the stereo image includes the stereo candidate image and an associated stereo companion image based on the plurality of digital images from the digital video; and
(e) storing the stereo image whereby the stereo image can be presented for viewing by a user,
wherein features and subfeatures are extracted from the plurality of digital images and used to compute the suitability scores, wherein the subfeatures include the mean of all motion vectors and a number of motion vectors that are substantially horizontal;
wherein the suitability score associated with a particular digital image from the digital video is based on a combination of detecting camera motion using digital images from the digital video and detecting objects in the particular digital image.

2. The method of claim 1 wherein the suitability score is based on
detecting camera motion using digital images from the digital video.

3. The method of claim 1 wherein the suitability score associated with a particular digital image from the digital video is based on detecting objects in the particular digital image.

4. The method of claim 1 , further including the user selecting at least one stereo image and sharing, storing, printing or displaying the selected stereo image.

5. The method of claim 1 , further including producing a print from at least one of the stereo images, wherein the print is an anaglyph image or a lenticular print.

6. The method of claim 2 , wherein the step of selecting a subset of digital images includes identifying panning camera motion in the digital video and selecting a stereo candidate image associated with the panning camera motion.

7. The method of claim 1 , further including the image capture device instructing a user on how to capture a video in anticipation of producing a stereo image.
