    摘要： In order to encrypt a part of an input image in such a manner that the encrypted part can be located for decryption, means for regularly converting pixel values in the area to be encrypted and generating a pattern unique to the pixel value conversion in order to encrypt the area to be encrypted; means for setting a specified positioning marker for locating an encryption position at two or more of the four corners of the area to be encrypted; and means for setting one or more checking marks for verifying appropriateness of a decrypted image in the encrypted area before the decryption are included.

    摘要： At the time of marker attachment (at the time of encryption), for example, image conversion in which pixels to be overwritten by a marker are selected and pruned in a distributed manner and the pruning positions are moved to a marker attachment position is performed, and the marker is attached to the marker attachment position obtained as a result. At the time of marker elimination (at the time of decryption), for example, image reverse conversion in which each pixel of the marker is moved to the original position before the marker attachment is performed, each moved pixel of the marker is recovered, and the marker is eliminated.

    摘要： When creating a marker, an encryption apparatus extracts each pixel value in a region and allows a storing unit to save, as restoration information, the high-order bits of each extracted pixel value. Then, the encryption apparatus creates a marker by changing the high-order bits of the pixel value in a region in which the marker is created and embeds encrypted information in an encrypted region specified by the marker. When decoding the encrypted information, a decoding apparatus detects the marker from a digital image, decodes the encrypted information in the encrypted region specified by the maker, and overwrites bits contained in the restoration information with the high-order bits of the pixel value of the marker.

    摘要： An image processing system includes: an image input unit which reads an image printed on a medium and generates electronic data representing the image; and a processing unit which corrects the image represented by the electronic data. The processing unit implements the functions of: detecting, from the image represented by the electronic data, a first pattern having a first size and shape that is attached to the image; measuring a degree of degradation by measuring an amount of displacement of the size of the detected first pattern from the first size; and correcting the image represented by the electronic data to reduce the degree of degradation.
