Image display device and image display method

An image display method of displaying an image stereoscopically by using an image display device including an aggregate of convex lenses arranged on a surface thereof with a predetermined lens pitch Px in at least one direction Dx (in which x is a suffix representing the direction);

• and a display unit displaying a plurality of element images on a focal plane surface of the convex lenses or near the focal plane surface in a manner aligned along the surface to thereby display the element images aligned in the direction Dx with an image pitch wx different from the pitch Px,
• wherein the element images are composed of an aggregation of a plurality of parallax component images, and a moiré stripe formed by shift in pitches between a plurality of convex lenses and a plurality of element images is stereoscopically displayed as an image.

An image display method of displaying an image as animation by using an image display device including an aggregate of convex lenses arranged on a surface thereof with a predetermined lens pitch Px in at least one direction Dx (in which x is a suffix representing the direction);

• and a display unit displaying a plurality of element images on a focal plane surface of the convex lenses or near the focal plane surface in a manner aligned along the surface to thereby display the element images aligned in the direction Dx with an image pitch wx different from the pitch Px,
• wherein the element images are composed of an aggregation of a plurality of frame component images, and a moiré stripe formed by shift in pitches between a plurality of convex lenses and a plurality of element images is displayed as an image of animation.
