Spatio-temporal light field cameras
First Claim
1. A method comprising:
- providing a plurality of light field cameras each having;
a micro photo-detector array device having a light detection surface anda micro lens array of micro lens elements;
whereby the micro photo-detector array device and the micro lens array are assembled together and temporally angularly articulated as a single assembly around two orthogonal axes parallel to a plane of the light detection surface of the micro photo-detector array device;
the temporal angular articulation being within a range of plus to minus a maximum angular articulation for each axis;
the periodicity of the temporal angular articulation being selected to enable temporal coverage of the maximum articulation angle within an image frame capture duration;
wherein the temporal angular articulation is either temporally continuous or discrete and has a repetition rate that is proportional to and synchronized with an image capture frame rate whereby the maximum angular articulation around each of the two axes determines the full angular extent of the light field camera, the angular coverage shape it subtends, and its aspect ratio;
embedding each light field camera in a respective mobile device;
interconnecting each mobile device to at least one host device through wireless or wireline networks or through bulk data transfer using flash memory modules;
exchanging light field camera output data between mobile devices that captured a different perspective of a viewing scene and the host device to form collective light field camera output data; and
using the collective light field camera output data to create a collective light field of the viewed scene.

Abstract
Spatio-temporal light field cameras that can be used to capture the light field within its spatio temporally extended angular extent. Such cameras can be used to record 3D images, 2D images that can be computationally focused, or wide angle panoramic 2D images with relatively high spatial and directional resolutions. The light field cameras can be also be used as 2D/3D switchable cameras with extended angular extent. The spatio-temporal aspects of the novel light field cameras allow them to capture and digitally record the intensity and color from multiple directional views within a wide angle. The inherent volumetric compactness of the light field cameras make it possible to embed in small mobile devices to capture either 3D images or computationally focusable 2D images. The inherent versatility of these light field cameras makes them suitable for multiple perspective light field capture for 3D movies and video recording applications.
