Abstract
Abstract This invention provides an image processing system comprising devices for producing image signals by scanning an original image, process units for generating video signals by processing the image signals, detector for detecting the coordinates of the original image and controller for storing the coordinate signals from the detecting means and for controlling the process units according to thus stored signals. <IMAGE>

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
147 words
An image processing system comprising: a plate (3) on which a plurality of original documents can be set at a set position; means (1) for producing image signals by scanning the plurality of original documents on said plate (3); and means (B) for reproducing images on different materials on the basis of the image signals, characterized by means (Fig. 17B) for detecting at least one of the size and set position of one of the plurality of original documents and for producing a detection signal representing the detected size or position; and means (CPU) for controlling said producing means (1) and said reproducing means (B) in accordance with the detection signal from said detecting means (Fig. 17B) in such a manner that images of the plurality of original documents can be reproduced by said reproducing means (B) on the different materials in succession with an interval therebetween.
Claim 2
Dependent Claim
43 words
An image processsing system according to claim 1, characterized in that said detecting means (Fig. 17B) determines at least one of the size and the position of the original document on the basis of the image signal produced by said producing means (1).
Claim 3
Dependent Claim
27 words
An image processing system according to claim 1 or 2, characterized in that said detecting means (Fig. 17B) determines a plurality of coordinates of the original document.
Claim 4
Dependent Claim
34 words
An image processing system according to one of the preceding claims, characterized in that said control means (CPU) determines the size of a material on which the image is reproduced by said reproducing means.
Claim 5
Dependent Claim
114 words
An image processing system according to one of the preceding claims, characterized in that said producing means comprises means (A) for scanning the plurality of original documents on said plate in succession by performing reciprocating movement plural times, and said controlling means (CPU) controls the reciprocating movement of said scanning means in accordance with the detection signal from said detection means in such a manner that the reciprocating movement for scanning of each of the plurality of the original documents by said scanning means is initiated at a common position with respect to said plate (3) and is terminated at different positions in accordance with the size or the position of the original document.
Claim 6
Dependent Claim
63 words
An image processing system according to one of the preceding claims, characterized in that said detecting means (Fig. 17B) comprises means (302) for discriminating that a certain image signal is continously produced for a predetermined period by said producing means (1), and said detecting means (Fig. 17B) detects the size or the position in accordance with the discrimination result of said discriminating means.
Claim 7
Dependent Claim
19 words
An image processing system according to claim 6, characterized in that the certain image signal represents a white image.
Claim 8
Dependent Claim
56 words
An image processing system according to claim 6 or 7, characterized in that said image processing system further comprises means (602, 602') for binary encoding the image signal and producing binary encoded data therefrom, wherein said discriminating means (302) discriminates that binary encoded data having a certain level is continuously produced by said binary encoding means.
Claim 9
Dependent Claim
46 words
An image processing system according to one of the preceding claims, characterized in that said detecting means (Fig. 17B) produces the position signal representing the size or the position of an area covering the original document when the original document is set obliquely on said plate.
Claim 10
Dependent Claim
53 words
An image processing system according to one of the preceding claims, characterized in that said detecting means (Fig. 17B) detects the size or the position on the basis of the image signal produced by said producing means by pre-scanning the original document independently of the reproducing of the image by said reproducing means.
