    摘要： An image detecting method comprises the steps of: a) searching for a pattern satisfying a predetermined commencement requirement by scanning an input image; b) using the pattern as a starting point, with referring to a dictionary storing therein distances between the center line and an edge of a detection target semicircle, determining for each of a predetermined number of main scan lines along a sub-scan direction whether or not a predetermined edge pattern occurs within a respective range of the distance of the dictionary; and c) determining a detection of the semicircle when the number of error lines on which the predetermined edge pattern does not occur within the respective range of the distance of the dictionary is less than a predetermined threshold.

    摘要： There are provided a data recording medium, a reading device for reading the data recording medium, a recording device for reading the data recording medium and recording data to other media, and methods thereof able to prevent forgery without comparing visible information and data stored in a built-in electronic circuit chip. The reading device is for reading a data recording medium including a sheet portion visibly printed with an image and a data storage unit recorded with control data. The reading device comprises a first reading unit adapted to optically read the image on the sheet portion, a second reading unit adapted to read the control data including read permission data indicating whether reading of the image is permitted, a determination unit adapted to determine whether reading of the image by the first reading unit is permitted based on the read permission data obtained by the second reading unit, and a controller adapted to control the first reading unit based on the determination by the determination unit.

    摘要： A reference-character size determination unit determines a reference-character size based on a distribution of sizes of particular continuous image parts, the continuous image parts constituting an image. An image part sorting unit sorts the particular continuous image parts into character image parts and other image parts based on the reference-character size. A rectangle determination unit determines a rectangle for each continuous image part, a size of the rectangle corresponding to a size of the corresponding continuous image part. The reference-character size determination means determines the reference-character size based on a distribution of sizes of the rectangles. The image part sorting means sorts the particular rectangles into rectangles for the character image parts and rectangles for the other image parts based on the reference-character size. The character image part integrating unit integrates the particular character image parts with each other when particular character image parts have a predetermined character relationship.

    摘要： A binarization method obtains an optimum threshold value for binarization which is used when converting a multi-level image data which describes an input image into a black-and-white bi-level image data. The binarization method includes the steps of counting a first number of black picture elements by varying a threshold value from a darkest tone level to a lightest tone level, counting a second number of picture elements having a tone level other than the lightest tone level, obtaining a percentage of the first number with respect to the second number for each of the varied threshold values so as to normalize a density of the input image, and determining the optimum threshold value for binarization based on the percentage which is obtained for each of the varied threshold values.

    摘要： A method for identifying a table region within an input image data of an original obtained by an optical character reader. The table region identification method comprises the steps of extracting first sets of runs of successive black picture elements from each of the lines of the input image data, unifying adjacent runs among the first sets of the runs into first rectangles, unifying second sets of runs within a second rectangle having a size greater than a prescribed size among the thus unified first rectangles to extract ruled lines, the second sets of the runs having a length greater than a prescribed length, and finally making a decision on whether the second rectangle constitutes a table region or any other region depending on the number of the ruled lines counted.
