Light field dislay, adjusted pixel rendering method therefor, and adjusted vision perception system and method using same addressing astigmatism or similar conditions

A device operable to dynamically adjust user perception of an input image, the device comprising:

• an array of digital display pixels;
• a corresponding array of light field shaping elements (LFSEs) shaping a light field emanating from said pixels;
• and
• a hardware processor operable on pixel data for the input image to output adjusted image pixel data to be rendered via said LFSEs to dynamically adjust perception of the input image as so rendered to at least partially accommodate a designated visual acuity accommodation by, for each given pixel, digitally:
• projecting a given ray trace between said given pixel and a given pupil location on a user pupil given a direction of a light field emanated by said given pixel given a corresponding LFSE;
• identifying a designated optical vision parameter for said given pupil location given said designated visual acuity accommodation;
• defining an adjusted image location on an adjusted image surface corresponding with said given pixel as a function of said designated optical vision parameter for said given pupil location;
• associating an adjusted image pixel value designated for said adjusted image location with said given pixel;
• and
• rendering each said given pixel according to said adjusted pixel value associated therewith, thereby perceptively rendering a perceptively adjusted version of the input image on said adjusted image surface that at least partially accommodates said designated visual acuity accommodation.

A computer-implemented method, automatically implemented by one or more digital processors, to dynamically adjust user perception of an input image to be rendered by an array of digital display pixels via a corresponding array of light field shaping elements (LFSE) to at least partially accommodate a designated visual acuity accommodation, the method comprising, for each given pixel:

• projecting a given ray trace between said given pixel and a given pupil location on a user pupil given a direction of a light field emanated by said given pixel given a corresponding LFSE;
• identifying a designated optical vision parameter for said given pupil location given said designated visual acuity accommodation;
• defining an adjusted image location on an adjusted image surface corresponding with said given pixel as a function of said designated optical vision parameter for said given pupil location;
• associating an adjusted image pixel value designated for said adjusted image location with said given pixel;
• and
• rendering each said given pixel according to said adjusted pixel value associated therewith, thereby perceptively rendering a perceptively adjusted version of the input image on said adjusted image surface that at least partially accommodates said designated visual acuity accommodation.

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 an array of digital display pixels and a corresponding array of light field shaping elements (LFSE) to at least partially accommodate a designated visual acuity accommodation, by, for each given pixel, digitally:

• projecting a given ray trace between said given pixel and a given pupil location on a user pupil given a direction of a light field emanated by said given pixel given a corresponding LFSE;
• identifying a designated optical vision parameter for said given pupil location given said designated visual acuity accommodation;
• defining an adjusted image location on an adjusted image surface corresponding with said given pixel as a function of said designated optical vision parameter for said given pupil location;
• and
• associating an adjusted image pixel value designated for said adjusted image location with said given pixel for perceptively rendering a perceptively adjusted version of the input on said adjusted image surface that at least partially accommodates said designated visual acuity accommodation.
