ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to the field of image processing, and more particularly to automatically extracting photographic images from a video.
BACKGROUND OF THE INVENTION
Historically, video cameras and still image cameras have been used for different applications and have occupied different consumer markets. Most still image cameras do not possess the image storage and rapid capture capability of video cameras and therefore are unsuitable for capturing and recording video clips. Conversely, the video resolution and quality produced by most video cameras are too low for producing high quality still images. Consequently, people who wish to capture both videos and high quality still images must usually have both a video camera and a still image camera.
SUMMARY OF THE INVENTION
A method and apparatus for generating photographs from a video is disclosed. Segments of the video for which frame-to-frame background motion is less than a threshold are identified and, for each of the segments, the video frames in the segment are combined to generate a photograph representative of the segment.
Other features and advantages of the invention will be apparent from the accompanying drawings and from the detailed description that follows below.
