Abstract
Abstract There is disclosed an apparatus for image reading or processing, that can precisely identify a particularly pattern, such as of banknotes or securities faithful copying of which is to be prohibited. The apparatus is provided with a detecting unit for detecting positional information of an original image, and a discriminating unit for extracting the pattern data of a certain part of the original image and discriminating whether the original image is the predetermined image, based on the similarity between the pattern data and the predetermined pattern.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
94 words
A controlling method for controlling an image forming apparatus which sequentially forms a plurality of color component images on a medium to produce a color image, said method comprising the steps of: inputting color image data representing an original; judging whether the original is a specific image based on the color image data; and controlling the image forming apparatus based on the judgment, in a case where the original is the specific image, such that accurate image forming of at least one, but not all, of the plurality of color component images is prevented.
Claim 2
Dependent Claim
94 words
A controlling method for controlling an image forming apparatus which sequentially forms a plurality of color component images on a medium to produce a color image, said method comprising the steps of: inputting color image data representing an original; judging whether the original is a specific image based on the color image data; and controlling the image forming apparatus based on the judgment, in a case where the original is the specific image, such that accurate image forming of at least one, but not all, of the plurality of color component images is prevented.
Claim 3
Dependent Claim
31 words
A method according to claim 1, wherein the image forming apparatus forms a plurality of color component images sequentially frame-by-frame in order to produce a color image having one image plane.
Claim 4
Dependent Claim
21 words
A method according to claim 1, wherein the color image data is generated by an image reader for scanning the original.
Claim 5
Dependent Claim
24 words
A method according to claim 3, wherein the image reader repeats the scanning in response to each of the plurality of color component images.
Claim 6
Dependent Claim
21 words
A method according to claim 1, wherein the judging of the specific image is based on matching of a predetermined pattern.
Claim 7
Dependent Claim
18 words
A method according to claim 5, wherein the predetermined pattern is a predetermined figure having a predetermined color.
Claim 8
Dependent Claim
31 words
A method according to claim 1, wherein a black component image is a last color component of the plurality of color component images to be formed by the image forming apparatus.
Claim 9
Dependent Claim
24 words
A method according to claim 1, wherein the controlling of the image forming apparatus is realized by modification of the last color component image.
Claim 10
Dependent Claim
17 words
A method according to claim 8, wherein the modification is realized by formation of a mirror image.
Claim 11
Dependent Claim
17 words
A method according to claim 8, wherein the modification is realized by synthesizing of a predetermined pattern.
Claim 12
Dependent Claim
102 words
A controlling apparatus for controlling an image forming apparatus which sequentially forms a plurality of color component images on a medium to produce a color image, comprising: input means for inputting color image data representing an original; judging means for judging whether the original is a specific image based on the color image data; and controlling means for controlling the image forming apparatus based on the judgment of said judging means, in a case where the original is the specific image, such that accurate image forming of at least one, but not all, of the plurality of color component images is prevented.
Claim 13
Dependent Claim
102 words
A controlling apparatus for controlling an image forming apparatus which sequentially forms a plurality of color component images on a medium to produce a color image, comprising: input means for inputting color image data representing an original; judging means for judging whether the original is a specific image based on the color image data; and controlling means for controlling the image forming apparatus based on the judgment of said judging means, in a case where the original is the specific image, such that accurate image forming of at least one, but not all, of the plurality of color component images is prevented.
Claim 14
Dependent Claim
31 words
An apparatus according to claim 11, wherein the image forming apparatus forms a plurality of color component images sequentially frame-by-frame in order to produce a color image having one image plane.
Claim 15
Dependent Claim
21 words
An apparatus according to claim 11, wherein the color image data is generated by an image reader for scanning the original.
Claim 16
Dependent Claim
24 words
An apparatus according to claim 13, wherein the image reader repeats the scanning in response to each of the plurality of color component images.
Claim 17
Dependent Claim
21 words
An apparatus according to claim 11, wherein the judging of the specific image is based on matching of a predetermined pattern.
Claim 18
Dependent Claim
18 words
An apparatus according to claim 15, wherein the predetermined pattern is a predetermined figure having a predetermined color.

Claim 20
Dependent Claim
24 words
An apparatus according to claim 11, wherein the controlling of the image forming apparatus is realized by modification of the last color component image.
Claim 21
Dependent Claim
17 words
An apparatus according to claim 18, wherein the modification is realized by formation of a mirror image.
Claim 22
Dependent Claim
17 words
An apparatus according to claim 18, wherein the modification is realized by synthesizing of a predetermined pattern.
