Abstract
A light-field display is provided that renders a light-field at one or more viewing apertures through a microlens array. The light-field display includes a display such as a monitor that is positioned behind the microlens array. The monitor and the microlens array are positioned so that light emitted from a pixel of the monitor reaches the one or more apertures through at most one microlens from the microlens array. For each microlens in the microlens array, the pixels of the monitor visible through that microlens of the microlens array at the one or more apertures is determined, and a light-field is then rendered at each of the one or more viewing apertures by rendering the determined pixels corresponding to each microlens.
Claims17
A light-field display comprising:
- a microlens array placed at a separation distance from a plurality of pixels of a display device;
- and
- a processor communicatively coupled to the display device and adapted to:
- determine a location of a first viewing aperture, wherein the first viewing aperture is sized to accommodate the size range of a human pupil;
- determine, for each microlens of the microlens array, the pixels of the display device that are visible at the first viewing aperture through the microlens;
- determine a location of a second viewing aperture;
- and
- determine, for each microlens in the microlens array, the pixels of the display device that are visible at the second viewing aperture through the microlens.
A light-field display comprising:
- a microlens array placed at a separation distance from a plurality of pixels of a display device;
- and
- a processor communicatively coupled to the display device and adapted to:
- determine a location of a first viewing aperture, wherein the first viewing aperture is a virtual viewing aperture;
- determine a location of a second viewing aperture;
- determine, for each microlens of the microlens array, the pixels of the display device that are visible at the first viewing aperture through the microlens;
- render, for each microlens of the microlens array, the determined pixels of the display device that are visible at the first viewing aperture through the microlens to display a light-field to a viewer at the first viewing aperture;
- determine, for each microlens in the microlens array, the pixels of the display device that are visible at the second viewing aperture through the microlens;
- and
- render, for each microlens in the microlens array, the determined pixels of the display device that are visible at the second viewing aperture through the microlens to display a light-field to the viewer at the second viewing aperture.
A method for generating a light-field display, comprising:
- positioning a microlens array at a microlens separation from a display device comprising a plurality of pixels;
- determining a location of a first viewing aperture in front of the microlens array, wherein the first viewing aperture is sized to accommodate the size range of a human pupil;
- for each microlens of the microlens array, determining pixels of the display device that are visible at the first viewing aperture through the microlens of the microlens array;
- for each microlens of the microlens array, rendering the determined pixels to display a portion of a light-field at the first viewing aperture through the microlens of the microlens array;
- determining a location of a second viewing aperture in front of the microlens array;
- for each microlens of the microlens array, determining pixels of the display device that are visible at the second viewing aperture through the microlens of the microlens array;
- and
- for each microlens of the microlens array, rendering the determined pixels to display a portion of the light-field at the second viewing aperture through the microlens of the microlens array.
