摘要： An image distortion correcting apparatus is provided with an image input section to input an image of a flat rectangular paper surface imaged by an imaging section, as an input image, an imaging position estimating section to estimate a relative imaging position of the imaging section with respect to the paper surface from four vertexes of the rectangular paper surface within the input image, a rectangular paper surface estimating section to estimate four vertexes of the rectangular paper surface within a three-dimensional space based on the imaging position, and an image correcting section to correct a perspective transformation distortion in the paper surface within the input image based on the imaging position and the four vertexes within the three-dimensional space, so as to output an output image.

摘要： A three-dimensional curved-surface model can be estimated by using both two-dimensional outlines obtained from a piece of image photographed from the top and a restriction that the paper is rectangular. Then, only the three-dimensional distortion in the image can be corrected based on the obtained three-dimensional curved-surface model.

摘要： After an original image, including half-tone dot meshed characters are inputted and a prescribed process is applied to the original image, black pixel connection patterns are extracted from a target process area. If the density of the extracted pattern exceeds prescribed density, it is judged that the pattern is half-tone dot meshed and both the respective average values and standard deviations of the vertical/horizontal sizes of the connection pattern are calculated. Then, respective threshold values are calculated based on both the respective average values and standard deviations, and half-tone dot patterns are eliminated. Furthermore, a pattern, the outline of which is long compared with an included black pixel, of all the remaining connection patterns is eliminated as an unnecessary pattern. Lastly, projections attached to a character are deleted and character extraction is terminated.

摘要： A multilevel image into which a color or a black-and-white image is converted is input, and a slightly indistinct binary image generating unit generates a slightly indistinct binary image that includes a slightly indistinct line pattern and does not include background noise. Additionally, a shape-preserved binary image generating unit generates a binary image that preserves the shape of a line pattern and includes background noise. These images are ANDed for each pixel, so that a binary image that preserves the shape of the line pattern and does not include the background noise is generated.
