Abstract
A display apparatus includes an image renderer per eye, at least one optical element arranged on an optical path between the image renderer and an image plane and a processor coupled to the image renderer. The processor or an image source communicably coupled to the processor is configured to generate a warped image based upon the optical properties of the first optical portion and the second optical portion. The processor is configured to render the warped image via the image renderer, wherein projections of a first portion and a second portion of the warped image are to be differently magnified by the first optical portion and the second optical portion of the at least one optical element, respectively, to produce the image on the image plane in a manner that the produced image appears de-warped to a user. The image has a spatially-variable angular resolution on an image plane.
