Display apparatus and method of displaying using context and focus image renderers and optical combiners
First Claim
1. A display apparatus comprising:
- at least one context image renderer for rendering a context image;
at least one focus image renderer for rendering a focus image;
an exit optical element; and
at least one optical combiner for optically combining a projection of the rendered context image with a projection of the rendered focus image to create a visual scene, an angular width of the projection of the rendered context image being greater than an angular width of the projection of the rendered focus image, the at least one optical combiner comprising;
a first semi-transparent reflective element having a first side and a second side, the first side facing the exit optical element; and
a second semi-transparent reflective element facing the second side of the first semi-transparent reflective element,wherein the at least one context image renderer is arranged in a manner that the projection of the rendered context image emanating therefrom is incident upon the first side of the first semi-transparent reflective element and reflected towards the exit optical element therefrom, andwherein the at least one focus image renderer is arranged in a manner that the projection of the rendered focus image emanating therefrom is incident upon the second side of the first semi-transparent reflective element and reflected towards the second semi-transparent reflective element therefrom, and is then reflected from the second semi-transparent reflective element towards the first semi-transparent reflective element, from where the projection of the rendered focus image is allowed to pass through towards the exit optical element.

Abstract
A display apparatus and method of displaying, via the display apparatus. The display apparatus includes context image renderer for rendering context image; focus image renderer for rendering focus image; exit optical element; and optical combiner for optically combining projection of the rendered context image with projection of the rendered focus image to create visual scene. The optical combiner includes first semi-transparent reflective element; and a second semi-transparent reflective element. The context image renderer is arranged in a manner that projection of rendered context image is incident upon first semi-transparent reflective element and reflected towards exit optical element therefrom. The focus image renderer is arranged in a manner that projection of rendered focus image is incident upon first semi-transparent reflective element and reflected towards second semi-transparent reflective element, and then reflected towards first semi-transparent reflective element, from where projection thereof is allowed to pass through towards exit optical element.

11. A method of displaying, via a display apparatus comprising at least one context image renderer, at least one focus image renderer, an exit optical element and at least one optical combiner, the at least one optical combiner comprising a first semi-transparent reflective element and a second semi-transparent reflective element, the first semi-transparent reflective element having a first side facing the exit optical element and a second side facing the second semi-transparent reflective element, the method comprising:
-
rendering a context image at the at least one context image renderer; rendering a focus image at the at least one focus image renderer; and using the at least one optical combiner to optically combine a projection of the rendered context image with a projection of the rendered focus image to create a visual scene, an angular width of the projection of the rendered context image being greater than an angular width of the projection of the rendered focus image, wherein the at least one context image renderer is arranged in a manner that the projection of the rendered context image emanating therefrom is incident upon the first side of the first semi-transparent reflective element and reflected towards the exit optical element therefrom, and wherein the at least one focus image renderer is arranged in a manner that the projection of the rendered focus image emanating therefrom is incident upon the second side of the first semi-transparent reflective element and reflected towards the second semi-transparent reflective element therefrom, and is then reflected from the second semi-transparent reflective element towards the first semi-transparent reflective element, from where the projection of the rendered focus image is allowed to pass through towards the exit optical element. - View Dependent Claims (12, 13, 14, 15, 16)
