description	Conventionally in a case of storing image data in an HDD, JPEG compression is executed to the image data for reducing the data size thereof and then the image data is stored. However, there are some cases where when the JPEG compression is executed to the image data including the copy-forgery-inhibited pattern and the like, degradation in image quality occurs. In regard to the image data including the copy-forgery-inhibited pattern and the like, the halftone processing is executed by the halftone processing unit without irreversible compression. Therefore, the image data can be stored in the HDD and like in a state of being small in a data size and with the image degradation restricted.
