Patent number: 11663945Abstract: A patch scanning display apparatus and a technique for reconstructing a target image frame on a projection surface is disclosed. The patch scanning display apparatus includes a backlight and a spatial light modulator (SLM). An optical scanning device scans the image projected by the SLM across the projection surface in accordance with a scan trajectory. A decomposition model is used to generate a set of image patches based on the target image frame and the scan trajectory. In an embodiment, the decomposition model is a projective non-negative matrix factorization model. The set of image patches are utilized to generate a modulation signal for the SLM and a binary backlight signal is then generated for each time step of the scan trajectory within a frame period to activate or deactivate the light-emitting elements of the backlight during the frame period at a high refresh rate while the projected image is scanned.Type: GrantFiled: July 20, 2021Date of Patent: May 30, 2023Assignee: NVIDIA CorporationInventor: Kaan Aksit

Patent number: 10699383Abstract: Methods are disclosed herein to blur an image to be displayed on a stereo display (such as virtual or augmented reality displays) based on the focus and convergence of the user. The methods approximate the complex effect of chromatic aberration on focus, utilizing three (R/G/B) simple Gaussian blurs. For transparency the methods utilize buffers for levels of blur rather than depth. The methods enable real-time chromatic-based blurring effects for VR/AR displays.Type: GrantFiled: December 10, 2018Date of Patent: June 30, 2020Assignee: NVIDIA Corp.Inventors: Morgan McGuire, Kaan Aksit, Pete Shirley, David Luebke

Patent number: 10481684Abstract: A method, computer readable medium, and system are disclosed for generating foveal images. The method includes the steps of redirecting first light rays towards an eye, where the first light rays are redirected by an optical combiner and produce a peripheral image and generating second light rays by a light engine. The second light rays are redirected towards the eye, where the second light rays intersect a first region of the optical combiner and converge at a nodal point within the eye and produce an inset foveal image positioned within at least a portion of the peripheral image. An origin of the second light rays is offset to intersect a second region of the optical combiner in response to a change in a gaze direction of the eye.Type: GrantFiled: November 16, 2017Date of Patent: November 19, 2019Assignee: NVIDIA CorporationInventors: Ward Lopes, Kaan Aksit

Patent number: 10401623Abstract: A display method and system are disclosed for virtual/augmented reality. The method includes the steps of generating an image by a projection engine and projecting light rays defining the image onto a diffuser holographic optical element (DHOE) located between an observer and a concave mirror element, where a concave surface of the concave mirror element faces the observer. The light rays are projected onto the DHOE at a reference angle that causes the light rays to be diffused to the concave surface of the concave mirror element and the diffused light rays are reflected back to the observer such that the observer perceives a virtual image that appears to the observer at a position behind the concave mirror element and further from the observer than the concave mirror element.Type: GrantFiled: November 9, 2018Date of Patent: September 3, 2019Assignee: NVIDIA CorporationInventors: Jonghyun Kim, Kaan Aksit, Ward Lopes, David Patrick Luebke

Patent number: 10317678Abstract: A method and system for operating a catadioptric glasses system is presented. The method includes the steps of generating an image via a light engine included in a glasses system and projecting the image onto a display that includes a diffusion layer positioned between a curved mirror and a user's retina. Light emitted from a surface of the diffusion layer is reflected off the curved mirror to the user's retina through the diffusion layer, and the diffusion layer is located between a focal point of the curved mirror and a surface of the curved mirror. The diffusion layer may be mechanically moved relative to the user's eye to enable light to pass through transparent regions in the diffusion layer in a time multiplexed fashion. The glasses system may also include a mirror stack to enable different virtual images to be formed at different depths.Type: GrantFiled: February 7, 2017Date of Patent: June 11, 2019Assignee: NVIDIA CorporationInventors: Kaan Aksit, David Patrick Luebke
