Abstract
The present invention is visual display system and method for producing a display image perceived as a far-focused virtual image by an operator. The display system includes a video image generation and display system, and a lens. The video image generation and display system includes an image generator and a video display electrically connected to the image generator. The image generator generates a video signal. The video display displays a video image based on the generated video signal. The lens is positioned between the operator and the video display. The lens allows the operator to perceive the displayed image as a far-focused virtual image.
Claims24
A visual display system for producing a display image perceived as a far-focused virtual image by an operator, the display system comprising:
- a video image generation system including an image generator for generating a video signal;
- a video display, operatively connected to the image generator, for displaying a video image based on the generated video signal;
- and
- a lens positioned between the operator and the video display, wherein the operator perceives through the lens the displayed image as a far-focused virtual image.
A method for producing a display image operator perceived as a far-focused virtual image by an operator, the method comprising:
- generating a video signal;
- and
- displaying a video image on a display device based on the generated video signal;
- and
- positioning a lens between the operator and the video display, wherein the operator perceives through the lens the displayed image as a far-focused virtual image.
A visual display system for producing a display image perceived as a far-focused virtual image by an operator, the display system comprising:
- a video image generation system including an image generator for generating a video signal;
- a video display, operatively connected to the image generator, for displaying a video image based on the generated video signal;
- and
- a lens positioned between the operator and the video display, wherein the lens is an achromatic lens that includes a planar surface, wherein the operator perceives through the lens the displayed image as a far-focused virtual image, and wherein the lens has an associated focal length designed such that the displayed image viewed through the lenses appears at a predetermined distance.
