Abstract

　本発明は、ぼやけが大きくなったり孤立点が生成されたりすることなく、良好な拡大画像を生成できる拡大画像生成装置を提供することを目的とする。そして、当該目的を達成するために、本発明に係る拡大画像生成装置（１）の補間方向決定部（５）では、メモリ制御部（２）から出力される補間位置情報、補間に必要な元画素データ、水平垂直方向補間部（４）から入力される補間方向有効判別条件、および制御部から入力端子（１３）を介して入力される補間方向優先順位設定により、複数の補間方向から１つの補間方向を決定する。補間方向決定部（５）において、補間方向評価部（５４）は、補間方向評価値算出部（５３）から出力される有効な斜め方向パターンの補間方向評価値と、入力端子（５９）から入力される補間方向優先順位設定とから、補間方向を決定する。
