PROBLEM TO BE SOLVED: To perform appropriate alignment not only in an area where an operator desires to align feature points in priority to other areas, but also in an area other than that area, in alignment among a plurality of images.SOLUTION: An image processing device includes: a feature point acquisition part for acquiring a priority feature point to be aligned in priority, and a non-priority feature point to be aligned in a priority lower than the priority feature point, of feature points acquired from at least either a first image or a second image a weight setting part for setting the weight of the non-priority feature point on the basis of an evaluation value to evaluate characteristics of the non-priority feature point, and setting the weight of the priority feature point of a value larger than the weight of the non-priority feature point and an alignment part for performing alignment between the first image and the second image on the basis of the priority feature point and the weight of the priority feature point, and the non-priority feature point and the weight of the non-priority feature point.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】複数の画像間の位置合わせにおいて、作業者が優先して一致させたい特徴点以外の領域おいても適切な位置合わせを行うこと。【解決手段】画像処理装置は、第1の画像と第2の画像の少なくともいずれか一方から取得した特徴点のうち、優先して位置合わせする優先特徴点と、優先特徴点よりも低い優先順位で位置合わせする非優先特徴点とを取得する特徴点取得部と、非優先特徴点の特性を評価する評価値に基づいて該非優先特徴点の重みを設定するとともに、該非優先特徴点の重みよりも大きい値の優先特徴点の重みを設定する重み設定部と、優先特徴点と優先特徴点の重み、および、非優先特徴点と非優先特徴点の重みに基づいて、第1の画像と第2の画像との位置合わせを行う位置合わせ部と、を有する。【選択図】 図1
