System and method for acquiring, editing, generating and outputting video data
First Claim
1. A method of generating and outputting video data corresponding to a plurality of video data frames, the method comprising:
- receiving refocusable light field video data, wherein the refocusable light field video data includes a plurality of temporally contiguous refocusable light field video frames, wherein each refocusable light field video frame includes an optical focus;
selecting a first key frame, wherein the first key frame corresponds to one of the plurality of refocusable light field video frames;
determining a virtual focus parameter for the first key frame;
selecting a second key frame, wherein the second key frame corresponds to one of the plurality of refocusable light field video frames which is temporally spaced apart from the first key frame such that a plurality of refocusable light field video frames are temporally disposed between the first and the second key frames;
determining a virtual focus parameter for the second key frame;
generating first video data corresponding to the plurality of refocusable light field video frames which are temporally disposed between the first and the second key frames using (i) the virtual focus parameter for the first key frame, (ii) the virtual focus parameter for the second key frame and (iii) the refocusable light field video data corresponding to the plurality of refocusable light field video frames which are temporally disposed between the first and the second key frames, wherein the first video data includes a plurality of video frames, each video frame including a virtual focus depth which is based on the virtual focus parameter for the first key frame and/or virtual focus parameter for the second key frame; and
outputting the first video data.

Abstract
Systems and methods directed to acquiring, generating, manipulating and/or editing refocusable video data/frames. The refocusable video frames may be light field video frames that may be focused and/or re-focused after acquisition or recording of such video frames. In one aspect, method comprises: selecting a first key frame, wherein the first key frame corresponds to one of a plurality of refocusable light field video frames, selecting a second key frame, wherein the second key frame corresponds to one of the plurality of refocusable light field video frames which is temporally spaced apart from the first key frame such that a plurality of refocusable light field video frames are temporally disposed between the first and the second key frames, determining a virtual focus parameters for the first key frame and the second key frame, and generating first video data.
