Abstract
Abstract Disclosed is an image processing apparatus for processing an input image and recording the image on a recording medium, and particularly a color copying apparatus which permits color copying of an original, and makes it possible to discriminate a specific original for the sake of prevention of forgery of a banknote, a negotiable instrument, or the like. The specific original is provided with copying processing which is different from that provided for an ordinary original.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
100 words
An image processing apparatus comprising supplying means (6;401) for supplying electrical image data representing an original to be processed, processing means (1;412) for processing the electrical image data supplied by said supplying means, and image outputting means (8;402) controlled by said processing means, characterised in that evaluating means (S113) for evaluating to what extent the image represented by the electrical image data data is similar to a predetermined image, and controlling means (S115) for generating a controlling signal for providing predetermined processing to the input data on an image in correspndence with the evaluation of said evaluating means (Figure 16).
Claim 2
Dependent Claim
53 words
An apparatus as claimed in claim 1, characterized in that said evaluating means comprises storage means (ROM423) for storing the feature of a predertermined original, and evaluates the likelihood by which the input image feature of an original to be copied is similar to said feature stored in said storage means (Figure 6).
Claim 3
Dependent Claim
37 words
An apparatus as claimed in claim 1 or 2, characterized in that the colour of the output image is changed in corresponderce with the degree of the likelihood of being similar to the predetermined image (Figure 16).
Claim 4
Dependent Claim
51 words
An apparatus as claimed in claim 1, 2 or 3, characterized in that said processing means includes an italic image/mirror image processing circuit (464) and a signal line (488) adapted to control the degree of an italic image with respect to the italic image/mirror image processing circuit (464)(Figures 17 to 18).
Claim 5
Dependent Claim
135 words
An apparatus an claimed in claim 1, 2 or 3, characterised in that said processing means includes an italic image/mirror image processing circuit (464) in which specific parameters are written, and in that a bus changeover signal means (481) is adapted to control a bus transceiver (472) with respect to a CPU bus (508), in that said evaluating means (450-5) constantly monitors the video colour signals by operating independently of the controlling means (CPU422), and in that conversion means are provided which are controlled independence upon the output of the determining means to effect a change to italic image, a change in size (reduction or elongation), the addition of characters (the word "COPY"), colour change, mosaic terture or blurring, each to an extent depending upon the degree of likelihood of similarlity (Figures 19 and 20).
Claim 6
Independent Claim
33 words
An apparatus as claimed the any one of claims 1 to 5, characterized in that said evaluating means evaluates on the basis of the electrical image data supplied by said supplying means (6;401).
Claim 7
Independent Claim
33 words
An apparatus as claimed in any one of claims 1 to 6, characterized in that said supplying means comprises an image reading device (6;61,62,63,65;401) for scanning an original and generating electrical image data.
Claim 8
Dependent Claim
26 words
An apparatus as claimed in claim 7, characterized in that the image reading device includes a sensor (63) for supplying data representing a plurality of colours.
Claim 9
Independent Claim
55 words
An apparatus as claimed in any one of claims 1 to 8, characterized in that said image outputting means is a laser printer (2114-2126) in which the laser beam is controlled by the evaluating means (2127) to effect a change in the output image independence upon the output state of the evaluating means (Figure 26).
Claim 10
Dependent Claim
77 words
An image processing method comprising the steps of supplying image data representing an original to be processed, processing the electrical image data supplied, and outputting the image under the control of the processed electrical image data, characterised by evaluating to what extent the image represented by the electrical image data is similar to a predetermined image, and generating a controlling signal for providing predetermined processing to the input data on an image in correspondence with the evaluation.
