  • Publication number: 20190394488
    Abstract: Methods and systems for light field image encoding and decoding are disclosed. According to some embodiments, the method receives scene metadata and input light field images associated with a scene. The method further performs a first encoding operation on the scene metadata and the input light field images to generate reference views and reference disparity information. The method further performs a second encoding operation based on the reference views, the reference disparity information, and synthesized residuals to output encoded light field data, where the encoded light field data comprises encoded reference views, encoded reference disparity information, and encoded synthesized residuals. The method further randomly accesses and selects a group of reference views and corresponding disparity information from the encoded light field data based on one or more selected regions of interest.

  • Patent number: 10448030
    Abstract: A compression method for high-resolution light field display is disclosed for applications in which computer memory constraints and latency are critical. The disclosed compression algorithm takes advantage of the 3D structure of a light field to compress the raw light field information with a fixed compression ratio and simple decoding instructions. The compressed high-resolution light field achieves a reduced bandwidth with acceptable quality, and is packed in a way that can be transmitted using common interfaces. In a preferred embodiment, the compression algorithm is used as a post-processing stage after light field information acquisition or after rendering. In a further preferred embodiment, the compression algorithm is incorporated into the acquisition or rendering procedure to reduce memory and rendering processing. These and further embodiments generate a compressed light field with all information required for direct display.

  • Publication number: 20190222821
    Abstract: A compressed light field imaging system is described. The light field 3D data is analyzed to determine optimal subset of light field samples to be (acquired) rendered, while the remaining samples are generated using multi-reference depth-image based rendering. The light field is encoded and transmitted to the display. The 3D display directly reconstructs the light field and avoids data expansion that usually occurs in conventional imaging systems. The present invention enables the realization of full parallax 3D compressed imaging system that achieves high compression performance while minimizing memory and computational requirements.

  • Patent number: 10070115
    Abstract: An innovative method for synthesis of compressed light fields is described. Compressed light fields are commonly generated by sub-sampling light field views. The suppressed views must then be synthesized at the display, utilizing information from the compressed light field. The present invention describes a method for view synthesis that utilizes depth information of the scene to reconstruct the absent views. An innovative view merging method coupled with an efficient hole filling procedure compensates for depth misregistrations and inaccuracies to produce realistic synthesized views for full parallax light field displays.

  • Patent number: 9930272
    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.

  • Publication number: 20170184776
    Abstract: Emissive micro-pixel spatial light modulators with non-telecentric emission are introduced. The individual light emission from each multi-color micro-scale emissive pixel is directionally modulated in a unique direction to enable application-specific non-telecentric emission pattern from the micro-pixel array of the emissive spatial light modulator. Design methods for directionally modulating the light emission of the individual micro-pixels using micro-pixel level optics are described. Monolithic wafer level optics methods for fabricating the micro-pixel level optics are also described. An emissive multi-color micro-pixel spatial light modulator with non-telecentric emission is used to exemplify the methods and possible applications of the present invention: ultra-compact image projector, minimal cross-talk 3D light field display, multi-view 2D display, and directionally modulated waveguide optics for see-through near-eye displays.
