摘要： PROBLEM TO BE SOLVED: To obtain a method for automatically recognizing defining information of each item of a slip by analyzing the table structure of the slip from the physical arrangement of the smallest rectangle consisting of vertical and horizontal ruled lines so as to determine an attribute of the smallest rectangle. SOLUTION: A reader 1000 optically reads a slip and a processor 1001 analyzes the slip recognize characters. An entry wen-yen dictionary 1003 in a memory 1002 stores a previously fixed entry wen-yen and its image data and a general dictionary 1004 stores a dictionary by each character recognizing category/character font in order to recognize the characters in a data part. In a CPU 1001, a ruled line extracting part 1005 extracts the ruled lines of the slip and the smallest rectangle consisting of the ruled lines and an analyzing part 1006 analyzes the arrangement of the extracted smallest rectangle to analyze table structure. An attribute deciding part 1007 decides the attribute of each smallest rectangle and a character recognizing part 1008 recognizes the characters in accordance with its attribute.

摘要： PROBLEM TO BE SOLVED: To highly guarantee the security of ciphered data stored in a storage medium. SOLUTION: Ciphered data 17 are stored in an area prepared in a storage medium 16 and allowed to be accessed by a user program and decoding algorithm for the data 17 is stored in an area not to be accessed by a user. A drive device loaded with the storage medium 16 extracts the algorithm 18 and decodes the data in accordance with the description of the algorithm 18. Since the data and its decoding algorithm are combined as a pair, a different ciphering method can be used in each data.

摘要： PROBLEM TO BE SOLVED: To attain the loading of a processing program and to flexibly protect the security of information stored in a loaded medium by adding a rewritable area to the processing part of an external storage. SOLUTION: A medium controller is provided with a processing means 1 and a loading means 3 and contained in an external storage. Then the medium controller performs the processing concerning the transfer of data between an information processor 4 and a storage medium 5. The medium 1 has a rewritable storage means 2 and performs the processing concerning the protection of the storage contents of the medium 5 based on the information stored in the area 2. The means 3 loads the information into the area 2 of the means 1. Thus the processing program to be carried out by the means 1 can be loaded and the storage contents of the medium 5 can be flexibly protected owing to the presence of the area 2 and the means 3 of the medium controller.

摘要： PROBLEM TO BE SOLVED: To precisely extract a dotted line though some of isolated vertexes constituting the dotted line are not extracted by judging the propriety of the candidate of the dotted line from the positional relation of a group of the isolated vertexes of extracted dotted line candidates. SOLUTION: An image scanner 1 reads a slip to convert it to a binary picture and an isolated vertex collecting part 20 executes isolated point extracting processing to all the points of the binary picture. A dotted line candidate extracting part 21 extracts isolated vertexes constituting the candidate of a dotted line. As the condition of the candidate of the dotted line, the positional relation between basically two adjacent isolated vertexes is judged. Namely, as the condition of the dotted line candidate, a distance, a shifting quantity and the difference of sizes between the two isolated vertexes are judged. A dotted line propriety checking part 22 compares the distance between the adjacent vertexes from the positional relation of the group of the whole vertexes to check the propriety of the dotted line. When these prescribed conditions are satisfied, further the inclination of the dotted line is checked. Thus, the dotted line can be extracted though some of the isolated vertexes constituting the dotted line are omitted.

摘要： PROBLEM TO BE SOLVED: To highly precisely detect the edge of an original even when a background image is instable, or the materials of the background and an original are similar to each other.
SOLUTION: This edge detection method is provided to detect edge pieces by executing retrieval to all retrieval lines covering an image from the edge of an image to a direction perpendicular to the edge, and to detect the edge pieces when any line where the edge piece can not be detected exists by executing retrieval to all the retrieval lines from the neighborhood of the center of the image to the edge of the image, and to decide a straight edge from those edge pieces. A plurality of edge candidates are obtained from the edge pieces to all the retrieval lines, and the optimal candidate is selected from among them. Rule lines are extracted from an original in the image, and the optimal candidate is selected based on its comparison with the ruled lines.

摘要： PROBLEM TO BE SOLVED: To provide a technology for enhancing a compression ratio of a color image and which is capable of sharply displaying the contour of characters or the like.
SOLUTION: A hue cluster classification / integration section 15 decreases the number of hue values on the basis of a hue histogram, assigns the hue values whose number is decreased to each pixel of a color image and classifies pixels having the same hue value to one cluster. Further, the hue cluster classifying / integrating section 15 integrates clusters whose difference in hues is a prescribed value or smaller. Moreover, the hue cluster classifying / integrating section 15 traces the contour of clusters whose size is less than a reference value to discriminate the clusters including many change points as a character region. A coding section 17 discriminates the characteristics of the clusters, on the basis of the result of the discrimination of a region discrimination section 14 and a result of the discrimination of rules lines and the character region to code the cluster, in response to a coding method which in turn, in response to the characteristics of each cluster.
