Abstract
A lattice plate is arranged in front of and in a spaced relation from an image display screen. An image to be displayed is divided into pixels each of which is modulated to a grid having a grid interval determined by far-near information carried by the pixel. When a viewer views the screen through the lattice plate, he/she can view a steroscopic image.
Claims6
A stereoscopic display apparatus comprising:
- image display means for displaying an image, wherein said image display means includes output means for dividing an image to be displayed into a plurality of pixels and converting each of the pixels into fine area grids having a grid interval being variable in accordance with distance information of the pixel, and for outputting the converted pixel to the image display screen;
- and
- a lattice plate arranged in front of and in a spaced relation from said image display screen, said lattice plate having a plurality of lattices.
A stereoscopic display method comprising the steps of:
- arranging a lattice plate having a plurality of lattices, in front of and in a spaced relation from an image display screen;
- dividing an image to be displayed into a plurality of pixels;
- and
- converting each pixel into grids having a grid interval determined by distance information of the pixel and outputting the converted pixel to the image display screen.
