Description

ステップＳ２２でハーフトーンパラメータを仮設定した後、次に、その仮設定したハーフトーンパラメータを用いてハーフトーン処理を行う（ステップＳ２４）。ディザ法の場合、このステップＳ２４は、閾値「０」から現閾値までのドットＯＮ画素を求めることに相当する。つまり、現閾値の階調を持つ単一階調の入力画像について、ディザマスクを適用したハーフトーン処理後のハーフトーン画像（ドット配置）を求めることに相当する。 After temporarily setting the halftone parameters in step S22, next, halftone processing is performed using the temporarily set halftone parameters (step S24). In the case of the dither method, this step S24 corresponds to obtaining dot ON pixels from the threshold value “0” to the current threshold value. That corresponds to obtaining the input image of a single tone having a tone of the current threshold, the halftone image after the halftone processing using the dither mask (dot arrangement).

グループ分けされた各グループに属する画素に対して、付加する誤差の「所定量」はグループ間で同じ値としてもよいし、グループ毎に異なる値としてもよい。また、「＋所定量」と「−所定量」は、絶対値が同じであってもよいし、絶対値が異なる値であってもよい。 For the pixels in each group that are grouped, the "predetermined amount" of additional to error may be the same value among groups, the value may be different for each group. Further, “+ predetermined amount” and “−predetermined amount” may have the same absolute value or may have different absolute values.

なお、上述した図３７から図４５で説明した実施形態における画像処理装置２０による処理の内容は、画像処理方法として把握することができる。 The contents of processing by the image processing apparatus 20 in the embodiment described in FIG. 4 5 37 described above can be grasped as an image processing method.
