  • Patent number: 7809206
    Abstract: An image processing apparatus generates a sub-self-similar set F, which is a subset of a self-similar set A with respect to contraction maps f1, . . . , fn and forms an image expressing the sub-self-similar set F. The apparatus includes a base-address-set designating section, a generation-rule acquiring section and a sub-self-similar set generating section. The base-address-set designating section selects m addresses each of which formed of infinite sequence of {1, . . . , n} and generates a base address set M including the selected addresses. The generation-rule acquiring section acquires a rule of generating a hypothetical sub-self-similar set G, which is a subset of a hypothetical self-similar set B with respect to n hypothetical contraction maps g1, . . . , gn, by using the generated base address set M. The sub-self-similar set generating section generates a sub-self-similar set F, which is a subset of the self-similar set A.

  • Patent number: 7526137
    Abstract: A domain block image is extracted from an original image by a domain block extracting section, and the domain block image is classified by a domain block classifying section. A range block extracting section extracts a range block image larger than the domain block image from the original image, and a reduced range block forming section reduces the range block image at the same size as the domain block image. A similarity degree judging section judges a similarity degree between the reduced range block image and the domain block image, and an improved domain block forming section performs a conversion of pixel values with respect to the reduced range block image in accordance with this similarity degree. Further, an edge enhancement processing section executes an edge enhancement processing as to the step edge portion so as to obtain an improved domain block image.

  • Patent number: 7155069
    Abstract: A first image enlargement processing section enlarges an original image to a specified size to generate an initial enlarged image. A domain block extraction section extracts a domain block image from the original image. A range block extraction section extracts a range block image from the neighborhood of the correspondence part of the domain block image in the initial enlarged image.

  • Patent number: 7046862
    Abstract: A domain block extracting unit extracts a domain block image from an original image. A range block extracting unit extracts a range block image from an area in the vicinity of the domain block image. The range block image has size being larger than a domain size and being smaller than an enlarged size. A reduced range block forming unit reduces the range block image to the domain size to produce a reduced range block image. A similarity judging unit compares each of the reduced range block images with the domain block image to select the highest similarity range block image. An enlarged range block forming unit forms an enlarged range block image by enlarging the size of the highest similarity range block image to an enlarged size thereof. An enlarged image acquiring unit produces an enlarged image of an original image by employing the respective enlarged range block images.
