Disclosed is an image processing method for processing image data having pixels consecutively arranged in two directions orthogonal to each other including setting a first pixel area configured by a first and a second predetermined numbers of pixels, summing up the individual pixel values of the first predetermined number of pixels in a column-wise manner with respect to first pixel columns arranged in one direction summing up the individual pixel values of the second predetermined number of pixels in a column-wise manner with respect to second pixel columns arranged in the other direction, identifying a count of stairs given by differences among the pixel values of the individual pixels in the first pixel area, respectively for one direction and for the other direction, and determining a pixel value of a predetermined pixel contained in the first pixel area.
