Optical Systems with Lens-Based Static Foveation - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240085706 titled 'Optical Systems with Lens-Based Static Foveation
Simplified Explanation
The abstract 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 the image in the light, creating a foveated image with higher resolution in the central region than in the peripheral region. Control circuitry on the device applies pre-distortion to the image to counteract distortion introduced by the lens.
- 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 to create a foveated image
- Foveated image has higher resolution in central region
- Control circuitry applies pre-distortion to counteract lens distortion
Potential Applications
This technology could be used in virtual reality headsets, augmented reality glasses, medical imaging devices, and military display systems.
Problems Solved
- Maximizes resolution at the eye box without increasing display size - Provides higher resolution in central region for improved visual experience
Benefits
- Enhanced visual experience with higher resolution in central region - Compact design without sacrificing image quality
Potential Commercial Applications
"Enhanced Resolution Display Technology for VR and AR Devices"
Possible Prior Art
One possible prior art could be the use of eye-tracking technology in VR headsets to adjust image resolution based on the user's gaze.
Unanswered Questions
How does the pre-distortion process work in detail?
The abstract mentions applying pre-distortion to counteract lens distortion, but it does not elaborate on the specific techniques or algorithms used for this process.
What are the limitations of the foveated imaging system?
While the abstract highlights the benefits of foveated imaging, it does not discuss any potential drawbacks or limitations of this technology.
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.
