Abstract

An image processing apparatus includes a 2D code detecting unit, a 2D code decoding unit, and an invalidation processing unit. The 2D code detecting unit is configured to detect a 2D code in a document image. The 2D code decoding unit is configured to try to decode the detected 2D code. The invalidation processing unit is configured to perform invalidation of the 2D code so as to make this 2D code undetectable by the 2D code detecting unit if the 2D code decoding unit failed to decode the 2D code.

Claims

1. An image processing apparatus, comprising:

a 2D code detecting unit configured to detect a 2D code in a document image;

a 2D code decoding unit configured to try to decode the detected 2D code; and

an invalidation processing unit configured to perform invalidation of the 2D code so as to make this 2D code undetectable by the 2D code detecting unit if the 2D code decoding unit failed to decode the 2D code.

2. The image processing apparatus according to claim 1, wherein:

the 2D code detecting unit is further configured to detect the 2D code by detecting a position detection pattern in the 2D code; and

the invalidation processing unit is further configured to invalidate the position detection pattern in the 2D code in order to make the 2D code undetectable.

3. The image processing apparatus according to claim 2, wherein the invalidation processing unit is further configured to cover a part or all of the position detection pattern of the 2D code with a message image in order to invalidate the position detection pattern of the 2D code.

4. The image processing apparatus according to claim 2, wherein the invalidation processing unit is further configured to remove a part or all of the position detection pattern of the 2D code in the document image in order to invalidate the position detection pattern of the 2D code.

5. The image processing apparatus according to claim 1, wherein the 2D code detecting unit is further configured to (a) try to detect the position detection pattern of the 2D code along a predetermined direction in the document image and (b) if the detection of the position detection pattern of the 2D code is failed, try to detect the position detection pattern of the 2D code along the predetermined direction again in the document image rotated by a predetermined angle.
