Patent number: 10991152Abstract: One embodiment of the present invention includes a parallel processing unit (PPU) that performs pixel shading at variable granularities. For effects that vary at a low frequency across a pixel block, a coarse shading unit performs the associated shading operations on a subset of the pixels in the pixel block. By contrast, for effects that vary at a high frequency across the pixel block, fine shading units perform the associated shading operations on each pixel in the pixel block. Because the PPU implements coarse shading units and fine shading units, the PPU may tune the shading rate per-effect based on the frequency of variation across each pixel group. By contrast, conventional PPUs typically compute all effects per-pixel, performing redundant shading operations for low frequency effects. Consequently, to produce similar image quality, the PPU consumes less power and increases the rendering frame rate compared to a conventional PPU.Type: GrantFiled: January 20, 2017Date of Patent: April 27, 2021Assignee: NVIDIA CorporationInventors: Yong He, Eric B. Lum, Eric Enderton, Henry Packard Moreton, Kayvon Fatahalian

Patent number: 10129524Abstract: According to various embodiments of the invention, a system and method are provided for enabling interaction with, manipulation of, and control of depth-assigned content in depth-enhanced pictures, such as virtual reality images. Depth-assigned content can be assigned to a specified depth value. When a depth-enhanced picture is refocused at a focus depth substantially different from the specified assigned depth value, the depth-assigned content may be omitted, grayed out, blurred, or otherwise visually distinguished. In this manner, content associated with an in-focus image element can be visually distinguished from content associated with an out-of-focus image element. For example, in at least one embodiment, depth-assigned content is visible only when an image element associated with the content is in focus (or nearly in focus).Type: GrantFiled: February 22, 2017Date of Patent: November 13, 2018Assignee: GOOGLE LLCInventors: Yi-Ren Ng, Eric Cheng, Chia-Kai Liang, Kayvon Fatahalian, David John Evans, Kira Wampler, Kristen Berman, Kurt Barton Akeley

Patent number: 8908058Abstract: According to various embodiments, multiple frames, each having image data and metadata, can be aggregated into pictures. The frames may come from different image capture devices, enabling aggregation of image data from multiple sources. Aggregation can be automatic, or it can be performed in response to user input specifying particular combinations of frames to be aggregated. In various embodiments, pictures are mutable, whereas immutability of the constituent frames is enforced. In various embodiments, certain metadata elements that are not essential to rendering can be selectively removed from frames, so as to address privacy concerns. In various embodiments, frames can be authenticated by the use of digests generated by a hash function.Type: GrantFiled: June 8, 2011Date of Patent: December 9, 2014Assignee: Lytro, Inc.Inventors: Kurt Barton Akeley, Yi-Ren Ng, Kenneth Wayne Waters, Kayvon Fatahalian, Timothy James Knight, Yuriy Aleksandrovich Romanenko

Depth-assigned content can be assigned to a specified depth value. When a depth-enhanced picture is refocused at a focus depth substantially different from the specified assigned depth value, the depth-assigned content may be omitted, grayed out, blurred, or otherwise visually distinguished.
