1. An image processing apparatus comprising:
- (a) input means for inputting image data, the image data comprising at least one of first image data and second image data;
(b) memory means for storing reference data in accordance with the first image data input by said input means;
(c) determination means for determining if an original represented by the second image data input by said input means has a predetermined visual pattern on the basis of the reference data stored in said memory means;
(d) mode setting means for setting a first mode in which the first image data is stored in said memory means as the reference data for the determination by said determination means and a second mode in which the determination by said determination means is performed by using the second image data input by said input means and the reference data stored in said memory means;
(e) discrimination means for discriminating whether an operator is permitted to set the first mode by said mode setting means in order to limit a person who can make said memory means store the first image data as the reference data; and
(f) control means for controlling the mode setting by said mode setting means in accordance with the discrimination result by said discrimination means.

Abstract
The present invention relates to an image processing apparatus and a method therefor for processing an input image and recording it on a recording medium. In particular, a predetermined original is registered in order to prevent bank bills or securities from being forged by color copying so that an original which is determined to be in coincidence with the registered original is subjected to a different processing from a usual processing.

16. An image processing apparatus for inhibiting accurate reproduction of an input image when the input image is determined to be an original having a predetermined visual pattern, comprising:
-
(a) memory means for storing first reference data for inhibiting the accurate reproduction, the first reference data being related to a first kind of original; (b) selectively operable writing means for writing second reference data into said memory means, the second reference data being related to a second kind of original different from the first kind of original; (c) discrimination means for discriminating whether an operator is permitted to selectively operate said writing means in order to limit a person who can make said memory means store the first reference data; and (d) control means for controlling the writing means in accordance with the discrimination result by said discrimination means. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26)

27. An image processing apparatus comprising:
-
(a) input means for inputting image data, the image data comprising at least one of first image data and second image data; (b) memory means for storing reference data in accordance with the first image data input by said input means; (c) process means for processing the second image data and generating reproduction data for image forming; (d) determination means for determining if an original represented by the second image data input by said input means has a predetermined pattern on the basis of the reference data stored in said memory means; (e) first control means for controlling a condition of said image processing apparatus in accordance with the determination of said determination means; (f) mode setting means for setting a first mode in which the first image data is stored in said memory means as the reference data for the determination by said determination means and a second mode in which the determination by said determination means is performed by using the second-image data input by said input means and the reference data stored in said memory means; (g) discrimination means for discriminating whether an operator is permitted to set the first mode by said mode setting means in order to limit a person who can make said memory means store the first image data as the reference data; and (h) second control means for controlling the mode setting by said mode setting means in accordance with the discrimination results by said discriminating means. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34, 35, 36, 37)

38. A method for changing reference data for inhibiting an accurate reproduction of an input image by a copying apparatus on the basis of comparison between reference data, the reference data comprising at least one of first and second reference data, and input image data, comprising the steps of:
-
(a) discriminating whether an operator is permitted to change the reference data in order to limit a person who can change the reference data; (b) setting the apparatus in a condition for changing the reference data in accordance with the discrimination result of said discrimination step; (c) canceling the first reference data which have been used for comparison and which are related to a first kind of original; and (d) setting second reference data to the apparatus, the second reference data being related to a second kind of original different from the first kind of original. - View Dependent Claims (39, 40, 41, 42, 43)

44. A method for changing reference data for inhibiting an accurate output of an input image by an image processing apparatus on the basis of comparison between reference data stored in a memory and input image data, comprising the steps of:
-
(a) discriminating whether an operator is permitted to change the reference data stored in the memory in order to limit a person who can change the reference data; and (b) changing the reference data stored in the memory in accordance with the discrimination result of said discrimination step. - View Dependent Claims (45, 46, 47)
