Optical Systems with Lens-Based Static Foveation - A simplified explanation of the abstract

This abstract first appeared for US patent application 18514710 titled 'Optical Systems with Lens-Based Static Foveation

Simplified Explanation

The patent application describes an electronic device with a display module that produces light containing an image, a lens that directs the light to a waveguide, and a waveguide that directs the light to an eye box. The lens applies non-uniform magnification to create a foveated image with higher resolution in the central region than in the peripheral region.

  • Display module produces light with an image
  • Lens directs light to a waveguide
  • Waveguide directs light to an eye box
  • Lens applies non-uniform magnification for foveated image
  • Higher resolution in central region than peripheral region
      1. Potential Applications

- Virtual reality headsets - Augmented reality glasses - Medical imaging devices

      1. Problems Solved

- Maximizes resolution without increasing display size - Provides higher resolution in central vision - Reduces distortion introduced by the lens

      1. Benefits

- Enhanced visual experience - Improved image quality - Efficient use of display space

      1. Potential Commercial Applications
        1. Enhanced Visual Technologies for Consumer Electronics


Original Abstract Submitted

An electronic device may include a display module that produces light having an image, a lens that directs the light to a waveguide, and a waveguide that directs the light to an eye box. The lens may produce a foveated image in the light by applying a non-uniform magnification to the image in the light. The non-uniform magnification may vary as a function of angle within a field of view of the lens. This may allow the foveated image to have higher resolution within the central region than in the peripheral region. Performing foveation using the lens maximizes the resolution of images at the eye box without increasing the size of the display module. Control circuitry on the device may apply a pre-distortion to the image that is an inverse of distortion introduced by the lens in producing the foveated image.
