Image processing apparatus, image scanning apparatus, image processing method, and image processing program










Image Number 3 for United States Patent #8121441.

A method and system for correcting the inclination of a scanned document in which two integers "a" and "b" are input to perform a rotation process. Each time an x-coordinate of a target pixel of a rotated image is changed by one pixel, "a" is added to a factor "kwy". When "kwy" becomes more than or equal to "b", "b" is subtracted from "kwy", and a y-coordinate of a corresponding target pixel of an original image is changed by one pixel. Each time a y-coordinate of the target pixel is changed by one pixel, "a" is added to a factor "kwx". When "kwx" becomes more than or equal to "b", "b" is subtracted from "kwx", and an x-coordinate of the corresponding target pixel of the original image is changed by one pixel. Four pixels including the corresponding target pixel are used to acquire a pixel value of the target pixel by two-dimensional interpolation by ratios acquired by dividing "kwx" and "kwy" respectively by "b".
