Abstract
To relieve fatigue of viewer's eyes, a binocular display system is equipped with a mechanical or electrical adjusting section for minimizing a separation between left and right virtual images for the left and right eyes. The adjusting section holds the arrangement of the four positions of left and right lenses (or curved mirrors) and left and right pictures produced by at least one display device in such a manner as to reduce the separation between the left and right virtual images of the left and right picture substantially to zero, and/or adjusts the arrangement of these four positions to move the left and right virtual images in a desired direction so that the left and right images remain optically coincident.
Claims33
A display system comprising:
- a display section including left and right display panels respectively displaying left and right pictures;
- an optical system including a left optical member for producing a left virtual image of said left picture and a right optical member for producing a right virtual image of said right picture;
- and
- an image adjusting means for adjusting the positions of the left and right display panels of said display section with respect to said left optical member and said right optical member so as to minimize a separation between the left and right virtual images, in response to a change in a distance between said optical system and said display section so that the left and right virtual images remain substantially coincident;
- wherein said image adjusting means includes a means for moving said left and right virtual images of said left and right pictures along at least one of a left and right direction, a far and near direction and an up and down direction;
- and
- wherein said left and right direction and said far and near direction are perpendicular to each other and parallel to an imaginary common axial plane containing both of a left optical axis of said left optical member and a right optical axis of said right optical member, and wherein said up and down direction is perpendicular to said common axial plane.

A display system comprising:
- a display section including left and right display panels respectively displaying left and right pictures;
- an optical system is a binocular system including a left optical member for producing a left virtual image of said left picture and a right optical member for producing a right virtual image of said right picture;
- and
- an image adjusting means for adjusting the positions of the left and right display panels of said display section with respect to said left optical member and said right optical member so as to minimize a separation between the left and right virtual images, in response to a change in a distance between said optical system and said display section so that the left and right virtual images remain substantially coincident;
- and
- wherein said image adjusting means comprises a first adjusting means for varying a left object distance of the left picture from said left optical member and a right object distance of the right picture from said right optical member, and a second adjusting means for varying an arrangement of the positions of said left and right optical members and said left and right pictures in dependence on said left and right object distances.
