Abstract

画像の急峻なエッジ部分で発生する不均一を解消するとともに、解像感の保たれた画像を得ること。欠落する色成分を有する画素を含んで構成されたカラー画像信号に対して第１の補間処理と第２の補間処理をそれぞれ行うことで第１補間画像信号と第２補間画像信号とを生成する補間処理部と、第１の補間処理の対象となる特定領域を特定するための評価値を画素毎に算出する評価値算出部と、評価値に基づいて特定領域を決定する領域決定部と、第１補間画像信号から特定領域の画像信号を抽出するとともに、第２補間画像信号から特定領域以外の領域の画像信号を抽出し、抽出した画像信号を合成することで補間後のカラー画像信号を作成する補間処理決定部とを具備する色補間装置を提供する。
