Abstract
A display apparatus has a display for displaying images for the right and left eyes, a lenticular lens arranged on the front surface of the display, and a detector for detecting the position of the head portion of an observer. A controller controls the images for the right and left eyes, so that the images are equally incident on the two eyes of the observer at the position detected by the position detector.
Claims8
A display apparatus comprising:
- image display means for displaying an image;
- a lenticular lens arranged on a front surface of said image display means;
- and
- control means for controlling a direction of light of said image display means, which emerges from said lenticular lens, wherein
- said control means rotates said lenticular lens and said image display means to have a longitudinal direction of said lenticular lens as a rotation axis.

A display apparatus comprising:
- image display means for displaying an image;
- a lenticular lens arranged on a front surface of said image display means;
- control means for controlling a direction of light of said image display means, which emerges from said lenticular lens;
- and
- variable apex angle prism means arranged in front of said lenticular lens, and wherein said control means controls an apex angle of said variable apex angle prism means.

A display apparatus comprising:
- image display means for displaying an image;
- a lenticular lens arranged on a front surface of said image display means;
- and
- detection means for detecting a gazing point of an observer on a screen of said image display means;
- control means for controlling an image position of at least one of the images for right and left eyes on said image display means so that the images for the right and left eyes become close to each other at the gazing point.
2 more elements
A stereoscopic display apparatus comprising:
- displaying means for displaying an image for a left eye of an observer and an image for a right eye of the observer;
- an optical member for directing light of the image for the left eye toward the left eye and directing light of the image for the right eye toward the right eye;
- means for rotating said displaying means and said optical member about a predetermined axis;
- and
- detecting means for detecting a position of the observer,
- wherein said displaying means and said optical member are rotated about the predetermined axis based on an output detection of said detecting means.

- displaying means for displaying an image for a left eye of an observer and an image for a right eye of the observer;
- an optical member for directing light of the image for the left eye toward the left eye and directing light of the image for the right eye toward the right eye;
- a variable apex angle prism disposed in front of said optical member;
- and
- detecting means for detecting a position of the observer,
- wherein an apex angle of said variable apex angle prism is changed based on an output detection of said detecting means.
