Abstract

　画像処理装置（２０）は、成分分離部（２２）、ノイズ低減処理部（２４）、エッジ情報取得部（２６）、ノイズ低減処理パラメータ取得部（２８）、成分合成処理部（３０）を含む。成分分離部（２２）は、原画像信号（Ｉ）を、骨格成分である第１成分（Ｕ）と、原画像信号（Ｉ）と第１成分（Ｕ）の残差から得られる第２成分（Ｖ）とを含む複数の成分に分離する。エッジ情報取得部（２６）は第１成分（Ｕ）のエッジ情報（ＥＩ）を得る。ノイズ低減処理部（２４）は少なくとも第２成分（Ｖ）の変動成分を低減する。ノイズ低減処理パラメータ取得部（２８）は、エッジ情報取得部（２６）によって得られたエッジ情報（ＥＩ）に基づき、ノイズ低減処理部（２４）のパラメータ（ＰＡ）を取得する。成分合成処理部（３０）は、第１成分（Ｕ）と、ノイズ低減処理部２４により変動成分が低減された第１成分（Ｕ）以外の成分とを合成する。
