Abstract
In embodiments of the invention, an apparatus may include a display comprising a plurality of pixels. The apparatus may further include a computer system coupled with the display and operable to instruct the display to display a deconvolved image corresponding to a target image, wherein when the display displays the deconvolved image while located within a near-eye range of an observer, the target image may be perceived in focus by the observer.
Claims23
An apparatus comprising:
- a display comprising a plurality of pixels;
- a computer system coupled with said display and operable to instruct said display to display a deconvolved image corresponding to a target image, wherein said computer system includes a processor configured to process information associated with said deconvolved image and a memory configured to store information related to said processing of said deconvolved image;
- wherein when responsive to said display displays displaying said deconvolved image while located within a near-eye range of an observer, said target image may be is perceived in focus by said observer, wherein a said processor of said computer system is operable to determine said deconvolved image by performing a convolution operation on a first function describing said target image with an inverse of a second function describing a blurring effect of a defocused eye attempting to view a plane outside of an accommodation distance of said eye and within said near-eye range, and wherein said processor is operable to filter said deconvolved image to be within a dynamic range of said display so that said display is operable to display said filtered deconvolved image.
An apparatus comprising:
- a computer system operable to determine a deconvolved image corresponding to a target image by performing a convolution operation on a first function describing said target image with an inverse of a second function describing a blurring effect of a defocused eye attempting to view a plane outside of an accommodation distance of said eye and within a near-eye range, wherein said computer system includes a processor configured to process information associated with said deconvolved image and a memory configured to store information related to said processing of said deconvolved image;
- and
- a first display communicatively coupled with said computer system, wherein said first display is operable to display said deconvolved image based on instructions received from said computer system, and wherein said computer system is operable to filter said deconvolved image to be within a dynamic range of said first display so that said first display is operable to display said filtered, deconvolved image, wherein said first display is located within said near-eye range of an observer associated with said eye.
A method comprising:
- receiving a target image;
- determining a deconvolved image corresponding to a target image by performing a convolution operation on a first function describing said target image with an inverse of a second function describing a blurring effect of a defocused eye attempting to view a plane outside of an accommodation distance of said eye and within a near-eye range, wherein said deconvolved image is filtered to be within a dynamic range of a display, wherein when responsive to said filtered deconvolved image is being displayed within said near-eye range of an observer, said target image may be is perceived in focus by said observer;
- and
- displaying said filtered deconvolved image on said display within said near-eye range of said observer.
