<p><P>PROBLEM TO BE SOLVED: To improve the definition of a character by suppressing framing that occurs in a peripheral part of the character. <P>SOLUTION: An original image is scanned for respective pixels to determine attributes indicating features for respective pixels of the scanned document. Pixel values included in an M×N (each of M and N is a natural number) including a pixel of interest are weighted, the pixel value of the pixel of interest is changed based on the weighted pixel values, and filtering is applied to pixel included in that area. Upon applying the filtering, a size of a filtering area is reduced according to the determined attributes. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
