Ranking key video frames using camera fixation
First Claim
Patent Images
1. A method for ranking video frames for a digital video having a time sequence of video frames, the method comprising:
- analyzing, by a computing device, the digital video to determine a camera fixation pattern;
determining, by the computing device, a set of video frames for the digital video; and
ranking, by the computing device, the video frames responsive to the camera fixation pattern, wherein the camera fixation pattern represents regions of an image scene being captured in each video frame of the set of video frames, and wherein the ranking the video frames is based on how many video frames comprise a similar captured region of the image scene.

12. A digital video camera system comprising:
-
an image sensor; an optical system configured to form an image of a scene onto the image sensor; a data processing system; and a memory system communicatively connected to the data processing system and storing instructions configured to cause the data processing system to implement a method for providing ranked video frames for a digital video, wherein the instructions comprise; instructions to capture a digital video using the image sensor, the digital video having a time sequence of video frames; instructions to analyze the digital video to determine a camera fixation pattern; instructions to determine a set of video frames for the digital video; and instructions to rank the video frames responsive to the camera fixation pattern, wherein the camera fixation pattern represents regions of an image scene being captured in each video frame of the set of video frames, and wherein the ranking the video frames is based on how many video frames comprise a similar captured region of the image scene. - View Dependent Claims (13, 14)
