Patent number: 11019347Abstract: 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.Type: GrantFiled: October 9, 2019Date of Patent: May 25, 2021Assignee: Ostendo Technologies, Inc.Inventors: Danillo Bracco Graziosi, Zahir Y.

Patent number: 10578882Abstract: 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.Type: GrantFiled: December 27, 2016Date of Patent: March 3, 2020Assignee: Ostendo Technologies, Inc.Inventors: Hussein S.

Publication number: 20190222821Abstract: 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.
