Patent Images
1. A method for generating a facsimile of an image comprising the steps of:
- generating signals representative of a particular shape;
arranging said signals into a field matrix of a plurality of pixel signals represenative of location of at least some points of the image field;
providing an array of electro-optical devices each transformable between a first condition and a different second condition in response to electromagnetic stimulation; and
using said pixel signals to stimulate the devices in said array to generate at said array a facsimile of said particular shape.

Abstract
A method and apparatus for operating an electro-optical array. Images indicative of shapes are obtained in some way, and these images are processed. The processed image is then used to drive an electro-optical array, such as a liquid crystal display, such that some parts of the display are opaque and other parts are transparent. A light source is directed through the liquid crystal array and thereby generates a light signal having the same shape as those parts of the liquid crystal array which are transparent.

8. A method for selectively directing electromagnetic radiation onto an image selected from a field of images comprising the steps of:
-
generating signals representative of a particular shape;
arranging said signals into a field that includes a matrix of a plurality of pixel signals indicative of said particular shape;
providing an array of electro-optical devices, each device transformable between a first electromagnetically opaque condition and a second electromagnetically transparent condition in response to appropriate applied signals;
projecting electromagnetic radiation onto said electro-optical devices such that said transparent devices pass said electromagnetic radiation and said opaque devices do not pass said radiation; and
applying said pixel signals to said array to transform the electro-optical devices corresponding to said pixel signals to said second condition to generate a transparent facsimile of the related image thereat, said electromagnetic radiation passing through said facsimile onto said selected image. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A system for generating a facsimile of an image comprising:
-
an array of electro-optical devices each transformable between a first condition and a different second condition in response to electromagnetic stimulation, means for generating signals representative of a particular shape;
means for processing said signals to obtain a plurality of pixel signals each representative of a location and at least intensity to a point of perception of the image;
means for selected the pixel signals representing the perception of the particular shape; and
controlling means for stimulating the devices in said array corresponding to said pixel signals to generate at said array a facsimile of said particular shape in elements of said array. - View Dependent Claims (16, 17, 18, 19, 20, 21)

22. A method for recreating a color image comprising steps of:
-
generating signals representative of each of the colors red, green and blue of the image;
arranging the signals of each color into a matrix of a plurality of pixel signals, each matrix representative of location and at least intensity to a point of perception of the color of the image;
providing an array of electro-optical devices for each of the colors red, green and blue, each device transformable between a condition of transparency and opacity in response to electromagnetic stimulation;
stimulating the devices in each array corresponding to correlating color pixel signals to generate at each array a transparent facsimile of the perceived color of the image; and
directing light of the colors red, green and blue through each of the corresponding arrays to recreate the image in color. - View Dependent Claims (23)
