Title (EN) IMAGE PROCESSING APPARATUS AND METHOD, AND IMAGE DISPLAYING APPARATUS
(FR) DISPOSITIF ET PROCÉDÉ DE TRAITEMENT D'IMAGE, ET DISPOSITIF D'AFFICHAGE D'IMAGE
(JA) 画像処理装置及び方法並びに画像表示装置
Abstract:
(EN) A first intermediate image generating means (1) generates an intermediate image (D1) obtained by extracting the components of a particular frequency band of an input image (DIN).  A second intermediate image generating means (2) generates an intermediate image (D2) having higher frequency components than the intermediate image (D1).  An intermediate image processing means (3M) generates an intermediate image (D3M) obtained by suppressing the minute vibrations included in the intermediate image (D1).  An intermediate image processing means (3H) generates an intermediate image (D3H) obtained by suppressing the minute vibrations included in the intermediate image (D2).  An adding means (4) adds together the input image (DIN), intermediate image (D3M) and intermediate image (D3H) to provide an ultimate output image (DOUT).  Even if the input image includes any folding components on the high frequency component side or includes no sufficient high frequency components, an enhanced image can be obtained without enhancing the noise.
(FR) Un premier moyen de génération d'image intermédiaire (1) génère une image intermédiaire (D1) obtenue en extrayant les composantes d'une bande de fréquence particulière d'une image d'entrée (DIN). Un second moyen de génération d'image intermédiaire (2) génère une image intermédiaire (D2) ayant des composantes de fréquence plus élevées que l'image intermédiaire (D1). Un moyen de traitement d'image intermédiaire (3M) génère une image intermédiaire (D3M) obtenue en supprimant les minuscules vibrations incluses dans l'image intermédiaire (D1). Un moyen de traitement d'image intermédiaire (3H) génère une image intermédiaire (D3H) obtenue en supprimant les minuscules vibrations incluses dans l'image intermédiaire (D2). Un moyen d'addition (4) additionne, ensemble, l'image d'entrée (DIN), l'image intermédiaire (D3M) et l'image intermédiaire (D3H) pour fournir une image de sortie définitive (DOUT). Même si l'image d'entrée comprend des composantes de repliement du côté composantes haute fréquence ou ne comprend pas de composantes haute fréquence suffisantes, une image améliorée peut être obtenue sans améliorer le bruit.
(JA)  第1の中間画像生成手段(1)において、入力画像(DIN)の特定の周波数帯域の成分を取り出した中間画像(D1)を生成し、第2の中間画像生成手段(2)において、中間画像(D1)よりも高い周波数成分を持つ中間画像(D2)を生成し、中間画像処理手段(3M)において、中間画像(D1)に含まれる微小な振動を抑制した中間画像(D3M)を生成し、中間画像処理手段(3H)において、中間画像(D2)に含まれる微小な振動を抑制した中間画像(D3H)を生成し、加算手段(4)において、入力画像(DIN)と中間画像(D3M)と中間画像(D3H)を加算して最終的な出力画像(DOUT)を得る。入力画像が、高周波数成分側に折り返し成分を含んでいる場合や高周波数成分を十分に含んでいない場合でも、ノイズを強調することなく強調処理画像を得ることができる。
