Abstract
The present invention operates in connection with refocusable video data, information, images and/or frames, which may be light field video data, information, images and/or frames, that may be focused and/or refocused after acquisition or recording. A video acquisition device acquires first refocusable light field video data of a scene, stores first refocusable video data representative of the first refocusable light field video data, acquires second refocusable light field video data of the scene after acquiring the first refocusable light field video data, determines a first virtual focus parameter (such as a virtual focus depth) using the second refocusable light field video data, generates 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 outputs the first video data.
