Patent ID: 8760566

Claim:
A light field video acquisition device comprising: optics; a photosensor array, configured to acquire first light field video data, and further configured to acquire second light field video data after acquisition of the first light field video data; a microlens array, disposed between the optics and the photosensor array so that light rays are directed onto the photosensor array via the optics and the microlens array; first memory, configured to store up to a predetermined amount of: first refocusable video data which is representative of the first light field video data; second refocusable video data which is representative of the second light field video data; first summary data derived from the first light field video data; and second summary data derived from the second light field video data; wherein the first and second refocusable light field video data each comprise a representation having at least four dimensions and comprising at least an indication of a direction of travel of light; and wherein the second summary data is derived after acquisition of the first light field video data; second memory, configured to store video data; and processing circuitry, coupled to the first memory and to the second memory, configured to: (i) determine a first virtual focus parameter using the second summary data; (ii) generate first video data using the first refocusable video data and the first virtual focus parameter, wherein the first video data includes a focus depth that is different from the optical focus depth of the acquired first light field video data; and (iii) cause an output device to output the first video data.
