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.
Claims7
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.

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.
