    摘要: A quantizing unit, error detector, error diffusion matrix, and adder quantize a pixel of interest of an input image by an error diffusion method. A calculation unit and gain adjuster calculate a value to be added to the pixel of interest with reference to quantized pixels. The adder adds the calculated value to the pixel of interest. A control unit controls the calculation of the gain adjuster.

    摘要: A halftone screen which is applicable to a low-resolution electrophotographic printer is created. Hence, dot-lattice points arranged in a predetermined region are displaced using rotation processing, the predetermined region is partitioned into polygons each of which surrounds the dot-lattice point. Then, a threshold matrix used to grow a halftone dot, which is surrounded by each polygon, in a direction of the displacement is generated.
