First Claim
1. An image projection system comprising:
- input means to produce electrical signals in response to an image to be projected;
serial-to-parallel shift register to receive the electrical signal from said input means;
decoder means connected to said input means to receive electrical signals;
a plurality of light modulator means arranged in an array of columns and rows, said columns connected to said serial-to-parallel shift register and said rows connected to said decoder, said modulator means selectively deflecting external light in response to signals from said shift register and said decoder; and
optical means to project an image from said selectively deflected light.

Abstract
An image projection system for producing a projected image in response to electrical signals which represent the image to be projected. The projection system includes input capability to produce electrical signals in response to an image to be projected. These electrical signals are then transmitted to a light modulator which receives light from an external source. The light modulator consists of arrays of deformable mirrors which selectively deflect the light from the external source in response to the electrical signals received from the input capability. The deflected light is absorbed by opaque stops. The undeflected light travels through optics which form the projected image. A printer using this image projection system is also disclosed. The printer further includes the ability to develop the projected image in such a manner that the image is transferrable to a paper surface in a printer in such a manner that the image is reproduced upon the surface in a printer form.
