Abstract
Abstract An image processor includes a light source, a scanner for scanning an original document using the light source, an imager for forming an image on the basis of light reflected from the original document and a light from the light source, a controller having a plurality of electro-mechanical transducer elements arranged in a light path from the light source to the imager, a generator for generating image data, and a driver for driving the controller in accordance with the image data. The driver drives the light controller in accordance with the image data, thereby causing the imager to form an image corresponding to the image data. The light source is adapted for forming an image corresponding to the original document and an image corresponding to the image data.

Claim 2
Dependent Claim
112 words
An image processing apparatus comprising: output means for outputting a first image as optical information; image forming means for forming an image using a light beam having the optical information from said output means; light control means having a plurality of electro-mechanical transducer elements, arranged in a light path from said output means to said image forming means; means for generating second image data; and drive means for driving said light control means in accordance with the second image data; wherein said drive means drives said light control means in accordance with the second image data so as to optically combine the first image and an image of the second image data.
Claim 3
Dependent Claim
25 words
An apparatus according to claim 1, wherein said output means outputs a reflected light from an original document as optical information by exposure-scanning the document.
Claim 4
Dependent Claim
141 words
An image processing apparatus comprising: a light source; means for scanning an original document using said light source; image forming means for forming an image on the basis of light reflected from the original document and a light from said light source; light control means having a plurality of electro-mechanical transducer elements arranged in a light path from said light source to said image forming means; means for generating image data; and drive means for driving said light control means in accordance with the image data; wherein said drive means drives said light control means in accordance with the image data, thereby causing said image forming means to form an image corresponding to the image data, and said light source is adapted for forming each of an image corresponding to the original document and an image corresponding to the image data.
Claim 5
Dependent Claim
141 words
An image processing apparatus comprising: a light source; means for scanning an original document using said light source; image forming means for forming an image on the basis of light reflected from the original document and a light from said light source; light control means having a plurality of electro-mechanical transducer elements arranged in a light path from said light source to said image forming means; means for generating image data; and drive means for driving said light control means in accordance with the image data; wherein said drive means drives said light control means in accordance with the image data, thereby causing said image forming means to form an image corresponding to the image data, and said light source is adapted for forming each of an image corresponding to the original document and an image corresponding to the image data.
Claim 6
Dependent Claim
51 words
An image processing apparatus according to claim 3 further comprising a standard white plate, said light source illuminating said standard white plate when the data image is to be formed so that a light reflected from said standard white plate is used as the light source to said light control means.
Claim 7
Dependent Claim
48 words
An image processing apparatus according to claim 3, wherein said drive means drives said light control means in accordance with the image data, thereby controlling light reflected from said original document to combine an image corresponding to the original document and an image corresponding to the image data.
Claim 8
Dependent Claim
36 words
