System, method, and computer program product to produce images for a near-eye light field display

摘要

A system, method, and computer program product are provided for producing images for a near-eye light field display. A ray defined by a pixel of a microdisplay and an optical apparatus of a near-eye light field display device is identified and the ray is intersected with a two-dimensional virtual display plane to generate map coordinates corresponding to the pixel. A color for the pixel is computed based on the map coordinates. The optical apparatus of the near-eye light field display device may, for example, be a microlens of a microlens array positioned between a viewer and an emissive microdisplay or a pinlight of a pinlight array positioned behind a transmissive microdisplay relative to the viewer.

主权项

1. A method, comprising:
identifying a ray defined by a pixel of a microdisplay and an optical apparatus of a near-eye light field display device; generating map coordinates corresponding to the pixel by:
determining a first displacement of the pixel relative to a reference point on the microdisplay,determining a second displacement within the optical apparatus of an optical center of the optical apparatus relative to the reference point on the microdisplay,computing, based on the first displacement and the second displacement, a point of intersection of the ray and a two dimensional virtual display plane, andconverting the point of intersection into the map coordinates; and computing, based on the map coordinates, a color for the pixel to produce a microdisplay image.
