Abstract
An object is to provide a copy function that guarantees intensity of embedded information. At the time of copying a printed material, embedded information is extracted from a scanned image obtained by scanning the target printed material. Then, in a case where it is confirmed that the copy-target printed material is an authentic document by the extracted embedded information, the embedded information extracted from the scanned image is reconfigured and printed and output.
Claims10
An image processing apparatus having a copy function, the image processing apparatus comprising:
- a memory that stores a program;
- and
- a processor that executes the program to perform:
- obtaining a scanned image by scanning a copy-target printed material;
- extracting embedded information from the scanned image by detecting a predetermined pattern from the scanned image;
- generating an image to be printed based on the scanned image;
- and
- performing print processing using the image to be printed, wherein
- in the generating, in a case where it is confirmed that the copy-target printed material is an authentic document by the extracted embedded information, the image to be printed is generated by reinforcing a portion at which intensity has become low in the predetermined pattern detected from the scanned image.
A control method of an image processing apparatus having a copy function, the control method comprising:
- an obtaining step of obtaining a scanned image by scanning a copy-target printed material;
- an extraction step of extracting embedded information from the scanned image by detecting a predetermined pattern from the scanned image;
- a generation step of generating an image to be printed based on the scanned image;
- and
- a printing step of performing print processing using the image to be printed, wherein
- at the generation step, in a case where it is confirmed that the copy-target printed material is an authentic document by embedded information extracted at the extraction step, the image to be printed is generated by reinforcing a portion at which intensity has become low in the predetermined pattern detected from the scanned image.
A non-transitory computer readable storage medium storing a program for causing a computer to perform a control method of an image processing apparatus having a copy function, the control method comprising:
- an obtaining step of obtaining a scanned image by scanning a copy-target printed material;
- an extraction step of extracting embedded information from the scanned image by detecting a predetermined pattern from the scanned image;
- a generation step of generating an image to be printed based on the scanned image;
- and
- a printing step of performing print processing using the image to be printed, wherein
- at the generation step, in a case where it is confirmed that the copy-target printed material is an authentic document by embedded information extracted at the extraction step, the image to be printed is generated by reinforcing a portion at which intensity has become low in the predetermined pattern detected from the scanned image.
An image processing apparatus having a copy function, the image processing apparatus comprising:
- a memory that stores a program;
- and
- a processor that executes the program to perform:
- obtaining a scanned image by scanning a copy-target printed material;
- extracting embedded information from the scanned image by detecting a predetermined pattern from the scanned image;
- generating an image to be printed based on the scanned image;
- and
- performing print processing using the image to be printed, wherein
- in the generating, in a case where it is confirmed that the copy-target printed material is an authentic document by the extracted embedded information, the image to be printed is generated by removing the embedded information within the scanned image and embedding information indicating being an authentic document anew, and
- wherein the removal of the embedded information is performed by applying a smoothing filer or an inverse filter obtained from the predetermined pattern to the scanned image.
