Abstract
An image display device includes a display unit which displays a first image and a second image, and a projection optical system which directs light of the first image and light of the second image toward a windshield. The display unit displays the first image and the second image in different display areas on the same plane. The projection optical system sets an image point of the light of the first image and an image point of the light of the second image, so that a first virtual image and a second virtual image are formed at positions having different distances from a viewing point within a visible area.
Claims15
An image display device which directs light of a first image and light of a second image toward a translucent member, reflects the light of the first image and the light of the second image from the translucent member toward a visible area, and displays a first virtual image corresponding to the first image and a second virtual image corresponding to the second image at positions visible through the translucent member when viewed from the visible area, the image display device comprising:
- a display unit configured to display the first image and the second image;
- and
- a projection optical system that directs the light of the first image and the light of the second image toward the translucent member,
- wherein the display unit displays the first image and the second image at different display areas on the same plane, and
- wherein the projection optical system sets an image point of the light of the first image and an image point of the light of the second image, so that the first virtual image and the second virtual image are formed at positions having different distances from a viewing point within the visible area.
A method for displaying images at a visible area, the method comprising
- displaying on a display unit a first image and a second image at different display areas on the same plane;
- directing light of the first image and light of the second image toward a translucent member with projection optics,
- directing the light of the first image and the light of the second image toward the translucent member;
- reflecting the light of the first image and the light of the second image from the translucent member toward a visible area;
- and
- displaying a first virtual image corresponding to the first image and a second virtual image corresponding to the second image at positions visible through the translucent member when viewed from the visible area,
- wherein the projection optics set an image point of the light of the first image and an image point of the light of the second image, so that the first virtual image and the second virtual image are formed at positions having different distances from a viewing point within the visible area.
