Description
コントーン画像４０をワーピングして、ビーム走査軌道の歪みを補正した後、このワーピングコントーン画像６０は、「非ワーピング」コントーンデータと同じように処理（レンダリング）されて、プリント準備の整った二進データとなる。つまり、ワーピングコントーン画像６０は、ＡＡＴ（エイリアス除去タグ付け）モジュール６２、及びＴＲＣ（階調再生曲線）モジュール６４へ送られる。ＡＡＴモジュール６２は、エイリアス除去することが決定されたワーピングピクセルにタグを付け、そのエイリアス除去タグをＴＲＣモジュール６４へ出力する。グレイピクセルのレンダリングは、そのグレイピクセルがエイリアス除去エッジを表しているか、均一領域を表しているかによって、異なった処理を行うのが望ましいので、ピクセルを分類する必要がある。ＡＡＴモジュール６２は、グレイピクセル近傍の分析を行って、そのグレイピクセルが真のグレイ値を表しているか、エイリアス除去エッジを表しているかを決定する。そのグレイピクセルが、暗領域と明領域との急激な変わり目にある（例えば、一方の側にほぼ飽和した（黒）ピクセルがあり、その反対側には背景（白）ピクセルがある）場合には、そのピクセルはエイリアス除去エッジを表している、とするのが適当である。一方、そのグレイピクセル近傍の値が全て類似している場合には、そのピクセルはエイリアス除去エッジではなく、真のグレイ値であろう。
