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:

an image scanning device;

said image scanning device acquiring a document image;

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

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

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;

a printing device that will print out document image data output by the image processing apparatus and print out said document image with the invalidated 2D code if the invalidation processing unit performed invalidation of the 2D code in the document image

wherein the 2D code detecting unit is further configured to (a) detect the position detection pattern of the 2D code along a predetermined direction in the document image by detecting an area that includes light and shade sections and determining if the ratio of high density parts and low density parts are in the ratio of 1;

1;

3;

1;

1 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.
