Abstract
Described are various embodiments of a light field display, adjusted pixel rendering method and computer-readable medium therefor, and vision correction system and method using same. In one embodiment, a computer-implemented method is provided to automatically adjust user perception of an input image to be rendered on a digital display via a set of pixels thereof, wherein the digital display has an array of light field shaping elements.
Claims23
A computer-implemented method, automatically implemented by one or more digital processors, to adjust perception of an input to be rendered via a set of pixels and a corresponding array of light field shaping elements (LFSE), the method comprising:
- designating an adjusted plane to provide a designated perception adjustment;
- for at least some of said pixels, digitally:
- projecting an adjusted ray trace linking a given pixel and a pupil location given a corresponding LFSE, to intersect said adjusted plane at a given adjusted plane location;
- and
- associating an adjusted pixel value designated for said given adjusted plane location with said given pixel for rendering a perceptively adjusted version of the input.
A non-transitory computer-readable medium comprising digital instructions to be implemented by one or more digital processors to automatically adjust perception of an input to be rendered via a set of pixels and corresponding array of light field shaping elements (LFSE), by:
- designating an adjusted plane to provide a designated perception adjustment;
- for at least some of said pixels, digitally:
- projecting an adjusted ray trace linking a given pixel and a pupil location given a corresponding LFSE, to intersect said adjusted plane at a given adjusted plane location;
- and
- associating an adjusted pixel value designated for said given adjusted plane location with said given pixel for rendering a perceptively adjusted version of the input.
A digital display device operable to adjust perception of an input to be rendered thereon, the device comprising:
- an array of pixels;
- an array of light field shaping elements (LFSE) to shape a light field emanating from at least some of said pixels;
- and
- a hardware processor operable on pixel data for the input to output adjusted pixel data to adjust perception of the input as rendered by:
- designating an adjusted image plane to provide a designated perception adjustment;
- for said at least some of said pixels, digitally:
- projecting an adjusted ray trace linking a given pixel and a pupil location given a corresponding LFSE, to intersect said adjusted plane at a given adjusted plane location;
- and
- associating an adjusted pixel value designated for said given adjusted plane location with said given pixel for rendering a perceptively adjusted version of the input.
