Abstract:
(EN) The present invention provides a device that makes it possible to acquire a difference image efficiently. This image processing device acquires an object image comprising a set of pixels that are arrayed discretely, sets a search region within the object image, and acquires, on the basis of values of pixels included within a partial area of the search region and/or interpolated values determined by interpolation of the pixels in the object image, the maximum value and/or minimum value of the pixel values or the interpolated values in the search region.
(FR) La présente invention concerne un dispositif qui permet d'acquérir efficacement une image de différence. Ce dispositif de traitement d'image acquiert une image d'objet comprenant un ensemble de pixels qui sont disposés de manière discrète, définit une région de recherche à l'intérieur de l'image d'objet, et acquiert, sur la base des valeurs de pixels inclus dans une zone partielle de la région de recherche et/ou des valeurs interpolées déterminées par interpolation des pixels dans l'image d'objet, la valeur maximale et/ou la valeur minimale des valeurs de pixel ou des valeurs interpolées dans la région de recherche.
(JA) 効率よく差分画像を取得することができる装置を提供する。画像処理装置は、離散的に配列された画素の集合で構成される対象画像を取得し、対象画像に探索領域を設定し、探索領域に含まれる部分領域において、部分領域に含まれる画素値又は対象画像の画素の補間により得られる補間値の少なくともいずれか一方の値に基づいて、探索領域内における画素値又は補間値の、最大値及び最小値の少なくともいずれか一方の値を取得する。
