Image processing for reproducing code image from original information
First Claim
Patent Images
1. An image processing device comprising:
- an extraction unit configured to extract original information from a code image in a read image obtained by reading a sheet on which the code image is formed;
a determination unit configured to determine whether an error detecting rate detected in a case where the extraction unit extracts the original information is not smaller than a predetermined value;
a generation unit configured to generate a code image using the original information extracted by the extraction unit in a case where the determination unit determines that the error detecting rate is not smaller than the predetermined value; and
a replacement unit configured to replace the code image in the read image with the generated code image.

Abstract
An image processing apparatus and method determine whether an error detecting rate of original information extracted from a code image in a read image obtained by reading a sheet on which the code image is formed, is not smaller than a predetermined value. When it is not smaller than a predetermined value, a code image is reproduced from the extracted original information and the code image in the read image is replaced therewith. One example of the code image is a barcode.

4. An image processing method comprising the steps of:
-
extracting original information from a code image in a read image obtained by reading a sheet on which the code image is formed; determining whether an error detecting rate detected in a case where the original information is extracted at the extracting step is not smaller than a predetermined value; generating a code image using the original information extracted at the extracting step in a case where it is determined that the error detecting rate is not smaller than the predetermined value in the determining step; and replacing the code image in the read image with the generated code image. - View Dependent Claims (5, 6, 7)
