Abstract:
(EN) This image processing device (1) is provided with: a high-resolution synthesis unit (13) which, in a high-resolution image space, aligns multiple images, in which the positions of a subject are shifted relative to each other, on the basis of the amount of shift, and synthesizes the multiple images to generate a high-resolution composite image; a low-resolution synthesis unit (14) which, on the basis of the shift amounts, aligns multiple images with each other in a low-resolution image space having a resolution the same as or lower than that of the multiple images, and synthesizes the multiple images by weighted addition to generate a low-resolution composite image; a feature quantity calculation unit (15) which calculates a feature quantity relating to the direction of change of a pixel value in each region of the low-resolution composite image; and an image correction unit (16) which corrects the high-resolution composite image on the basis of the feature quantity.
(FR) L'invention concerne un dispositif de traitement d'image (1) comprenant : une unité de synthèse haute résolution (13) qui, dans un espace d'image haute résolution, aligne des images multiples, dans lesquelles les positions d'un sujet sont décalées les unes par rapport aux autres, en fonction de la quantité de décalage, et synthétise les images multiples afin de générer une image composite haute résolution ; une unité de synthèse basse résolution (14) qui, en fonction des quantités de décalage, aligne des images multiples les unes avec les autres dans un espace d'image basse résolution présentant une résolution inférieure ou égale à celle des images multiples, et synthétise les images multiples par addition pondérée afin de générer une image composite basse résolution ; une unité de calcul de quantité de caractéristique (15) qui calcule une quantité de caractéristique relative à la direction de changement d'une valeur de pixel dans chaque zone de l'image composite basse résolution ; et une unité de correction d'image (16) qui corrige l'image composite haute résolution en fonction de la quantité de caractéristique.
(JA) 画像処理装置(1)は、被写体の位置が相互にずれている複数枚の画像を位置ずれ量に基づいて高解像度画像空間上で相互に位置合わせし、複数枚の画像を合成して高解像度合成画像を生成する高解像度合成部(13)と、複数枚の画像を位置ずれ量に基づいて複数枚の画像と同一またはそれよりも低い解像度の低解像度画像空間上で相互に位置合わせし、複数枚の画像を重み付け加算により合成して低解像度合成画像を生成する低解像度合成部(14)と、低解像度合成画像の各領域における、画素値の変化方向に関する特徴量を算出する特徴量算出部(15)と、特徴量に基づいて高解像度合成画像を補正する画像補正部(16)とを備える。
