Abstract:
1. A method for producing a print by exposing an image onto a photosensitive material, comprising the steps of: extracting character image data and pictorial image data separately from original image data, which originally include said character image data and said pictorial image data; applying a first image-processing operation to said character image data by employing a first LUT for converting image values of pixels, represented by said character image data, to first exposure control values, so as to generate revised character-image data, which represent said first exposure control values; applying a second image-processing operation to said pictorial image data by employing a second LUT for converting image values of pixels, represented by said pictorial image data, to second exposure control values, so as to generate revised pictorial-image data, which represent said second exposure control values; combining said revised character-image data with said revised pictorial-image data, so as to generate processed image data, which include both said revised character-image data and said revised pictorial-image data; and forming an output image on said photosensitive material, based on said processed image data, so as to produce said print.
