    摘要: A color image input from a document image inputting unit is converted into a gray-scale image by a brightness image extracting unit. The gray-scale image is then converted into an image having a higher resolution according to the resolution of the original gray-scale image. When this conversion is performed, subpixels are generated between the original pixels, and the values of the subpixels are obtained with an interpolation method. Furthermore, a threshold value for a binarization process is generated by using an original pixel value and a subpixel value. The characters included in the binarized image are recognized by a binary image recognizing unit, and a recognition result is output from a recognition result outputting unit.

    摘要: A document image tilt detection unit extracts a set of elements forming a character from a document image, extracts candidates for horizontal and vertical lines based on the character elements, estimates the reliability of each candidate for a line, and extracts a set of probable lines. Then, it estimates the tilt of the document image based on the arrangement of the character elements belonging to the line elements in the set of probable lines. A layout analysis unit extracts a set of lines in a fixed line direction from a set of basic elements forming the document image, and reciprocally performs the extraction of a column based on the correlation between lines and the extraction of a line based on the restrictions of the column. By providing the document image tilt detection unit and the layout analysis unit, the tilt of the document image containing both vertical and horizontal character lines can be detected, and lines and columns can be extracted at a high speed with high precision.
