Abstract

Disclosed is an image processing apparatus having a discrimination function for identifying a specific original (e.g., a banknote). The apparatus inputs pattern data which is obtained by reading a specific original, stores the inputted pattern data, synthesizes the stored pattern data with inputted original image data, and stores the result.

Claims

1. An image processing apparatus comprising:

image reading means for reading an original, and for generating image data;

a member, which holds predetermined information, placed in the apparatus in a position to be read by said image reading means; and

addition means for adding a predetermined pattern based on the predetermined information to an image represented by the image data generated by said image reading means,

wherein the predetermined information corresponds to identification information unique to an individual apparatus.

2. The apparatus according to claim 1, wherein said image reading means includes a linear sensor for generating the image data.

3. The apparatus according to claim 1, wherein said member represents a bar code.

4. The apparatus according to claim 1, wherein said member is placed in an almost undetachable position of the apparatus.

5. The apparatus according to claim 1, wherein the identification information is a manufacturer'"'"'s serial number.

6. The apparatus according to claim 1, wherein said addition means repeatedly adds the pattern at a predetermined interval.

7. An image processing apparatus comprising:

image reading means for reading an original, and for generating image data;

a member, which holds identification information corresponding to said apparatus, placed in said apparatus at a position to be read by said image reading means; and

control means for controlling the apparatus in accordance with the identification information read from said member,

wherein the identification information is unique to an individual apparatus.

8. The apparatus according to claim 7, wherein said image reading means includes a linear sensor for generating the image data.

9. The apparatus according to claim 8, wherein said member is represents a bar code arranged in the same direction as the sensing direction in the linear sensor.

10. The apparatus according to claim 8, wherein said member is represents a bar code arranged in a direction perpendicular to the sensing direction in the linear sensor.

11. The apparatus according to claim 7, wherein said member is placed in an almost undetachable position of the apparatus.
