    • In the binarization processing method for multivalued image to reproduce the original image of the present invention, to the gradation value of one pixel, of the original image binary values are outputted as halftone dot by density pattern method, and the error is diffused to the surrounding pixels of said pixel using an area-type density expression pattern table.
      Said area-type density expression pattern table is obtained in such a manner that a basic output priority matrix having output priority rank as the element is prepared,a rotated basic output priority matrix is obtained by repeating said basic output priority matrix in X and Y directions and rotating it by the angle ϑ, then an output priority matrices corresponding to mesh units is obtained in which the element of said output priority matrices is corresponed to equal or nearest element of said rotated output priority matrix.

    • A method of distinguishing non-image areas in the form of defects, stains or the like on a plate-making film or a photographic printing paper from an image area, a method of automatically performing an opaquing operation and an apparatus for carrying out the opaquing method are disclosed. An original image to be inspected is sequentially read from line to line by a scanning/reading device such as a line sensor or the like so that the non-image areas are distinguished from the image area in accordance with a so-called conjunction-method based on continuity of scanned pixels. The distinguished pixels are bundled and outputted to the opaquing apparatus. The opaquing apparatus is operated such that the non-image areas are stopped out in a stopping-out unit using a thermal trasfer tape on which thermally fusible material to be placed on the non-image areas is carried.
