摘要： In an image encryption apparatus, each of pixel-value inverse-converters applies pixel-value inverse-conversion on an input image in each of previously-encrypted areas. An image combiner superimposes images with inversely-converted pixels in the previously-encrypted areas to the input image to obtain a ready-to-encrypt image. An image encryptor scrambles blocks in the ready-to-encrypt image. A pixel-value converter applies pixel-value conversion on each of scrambled blocks to obtain a multiply-encrypted image. In an image decryption apparatus, a pixel-value inverse-converter applies pixel-value inverse-conversion on each scrambled block in the multiply-encrypted image to obtain a dot-erased image. An image decryptor inversely scrambles the scrambled blocks in the dot-erased image to obtain a decrypted image. Each of pixel-value converters applies pixel-value conversion on the decrypted image in each of previously-encrypted areas. An image combiner superimposes images with converted pixels in the previously-encrypted areas to the decrypted image to obtain a previously-encrypted image.

摘要： A high-definition magnified image is obtained by simple computation. A magnified image is obtained by obtaining a deteriorated image on the basis of an input original image, determining enhancement filters used for individual small areas of the original image using the deteriorated image at least, performing a filtering process by applying the filters thus determined to the individual small areas to achieve enhancement, and interpolating the image for magnification.

摘要： A block where basic units of a background pattern are arranged two-dimensionally is formed so as to stably read buried information from a printed background pattern. Binary or multivalued number is assigned to the block to express information. When a binary number (bit) is assigned to a block made up of background patterns in double size, error correction can be made if an error occurs only in one background pattern while reading the block. In each background pattern, a diagonal lacking its center part is drawn, and isolated dots are placed along the other diagonal. With this, while ensuring the stability of reading the buried information after the read by a scanner, the uniformness of appearance of the printed object can be ensured.

摘要： A prediction error generating unit generates a predictive vector from the motion vectors of a plurality of adjacent blocks, and obtains a difference from a target vector. A plurality of variable-length coding units respectively encode the output of the prediction error generating unit with different encoding methods. A determining unit estimates the accuracy of the predictive vector generated by the prediction error generating unit based on the degrees of non-uniformity of the motion vectors of the plurality of adjacent blocks. A selecting unit selects one of the encoding results obtained by the plurality of variable-length coding units.

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.
