Vision correction system and method, light field display and light field shaping layer and alignment therefor

A computer-implemented method, automatically implemented by one or more digital processors, to automatically adjust user perception of an input image to be rendered by an array of pixels via a microlens array disposed relative thereto to shape a light field emanating therefrom and thereby at least partially govern a projection thereof from said array of pixels toward a viewer to at least partially address a viewer's reduced visual acuity, the method comprising:

• digitally mapping the input image on an adjusted image plane designated to provide the user with a designated image perception adjustment;
• associating adjusted image pixel data with at least some of said pixels according to said mapping, and further according to a distance between said microlens array and said pixels, wherein said distance is shorter than a focal length of said microlens array so to produce a divergent light field therefrom;
• and
• rendering said adjusted image pixel data via said pixels thereby rendering a perceptively adjusted version of the input image when viewed through said microlens array to at least partially address the viewer's reduced visual acuity.

A non-transitory computer-readable medium having instructions stored thereon, to be automatically implemented by one or more digital processors, to automatically adjust user perception of an input image to be rendered by an array of pixels via a microlens array disposed relative thereto to shape a light field emanating therefrom and thereby at least partially govern a projection thereof from said array of pixels toward a viewer to at least partially address a viewer's reduced visual acuity, the instructions comprising instructions to:

• digitally map the input image on an adjusted image plane designated to provide the user with a designated image perception adjustment;
• associate adjusted image pixel data with at least some of said pixel arrays according to said mapping, and further according to a distance between said microlens array and said pixels, wherein said distance is shorter than a focal length of said microlens array so to produce a divergent light field therefrom;
• and
• render said adjusted image pixel data via said pixels thereby rendering a perceptively adjusted version of the input image when viewed through said microlens array to at least partially address the viewer's reduced visual acuity.
