摘要： An image processing system for reading multi-level image data corresponding to each pixel of an input image from a multi-tone-level draft image such as a photograph and correcting a density level at each of the pixels, which is represented by the obtained image data, and outputting data representing corrected density levels. The image processing system first performs an appropriate sampling of the read image data of the pixels at a sampling rate in such a manner to enable reference to the density levels at the pixels when correcting the density levels. The sampling rate is most appropriately predetermined.
