Display apparatus and method of producing images having spatially-variable angular resolutions

A display apparatus for producing an image having a spatially-variable angular resolution on an image plane, the display apparatus comprising:

• an image renderer per eye;
• at least one optical element arranged on an optical path between the image renderer and the image plane, the at least one optical element comprising at least a first optical portion and a second optical portion having different optical properties with respect to magnification;
• and
• a processor coupled to the image renderer, wherein 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,
• wherein 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, and
• wherein, when generating the warped image, the processor or the image source is configured to adjust an intensity of the first portion and the second portion of the warped image in a manner that, upon being differently magnified, the projections of the first portion and the second portion of the warped image produce the image on the image plane that appears to have a uniform brightness across the image.
