Abstract:
To generate the pixel value of one interpolation point from the pixel values of the four original pixels in the surroundings of the interpolation point, when the pixel values of the four involve a predetermined density difference, a printer uses the corrected inverse distance value in place of the inverse distance value found according to general bilinear interpolation.
