<P>PROBLEM TO BE SOLVED: To provide an image processor for generating pixels based on a one-dimensional inclination of a function showing pixel values of an input image. <P>SOLUTION: A reference image extracting part 2201 acquires an angle contained in input data constancy information, or information of an area, and an input image data to be output to an approximation function estimating part 2202. The approximation function estimating part 2202 estimates an approximation function for expressing change of the pixel values in the image data, based on the input image data and the data constancy information input hereinbefore, and outputs the estimated approximation function to a differential processing part 2203. The differential processing part 2203 finds a prescribed one-dimensional differential value on the input image, based on the input approximation function, and outputs it. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
