Abstract:
Certain systems and methods are directed to acquiring, generating, manipulating and/or editing (for example, focusing or refocusing) refocusable video data, information, images and/or frames. The refocusable video data, information, images and/or frames may be light field video data, information, images and/or frames, that may be focused and/or re-focused after acquisition or recording of such video data, information, images and/or frames. In one aspect, a method of generating video data of a scene using a video acquisition device which acquires refocusable light field video data is disclosed, the method comprising (a) acquiring first refocusable light field video data of a scene, (b) storing first refocusable video data which is representative of the first refocusable light field video data, (c) acquiring second refocusable light field video data of the scene after acquiring the first refocusable light field video data, (d) determining a first virtual focus parameter (for example, a virtual focus depth) using the second refocusable light field video data, (e) generating first video data using the stored first refocusable video data and the first virtual focus parameter, wherein the first video data includes a focus depth that is different from an optical focus depth of the first refocusable light field video data, and (f) outputting the first video data to, for example, memory, a video display, processing circuitry, and/or a recording device.
