PROBLEM TO BE SOLVED: To provide an image processor, a program and an image processing method or the like for performing image summarization processing of suppressing the generation of a region which becomes unobservable due to the deletion of an image by using deformation information, and for improving the efficiency of the image summarization processing by using an unnecessary region at that time.SOLUTION: An image processor includes: an image sequence acquisition part 200 for acquiring an image sequence having a plurality of constructed images and a processing part 100 for performing image summarization processing of generating a summarized image sequence by deleting a part of the plurality of constructed images of the image sequence. The processing part 100 selects a reference image and a determination object image from among the plurality of constructed images, and detects the unnecessary region of the determination object image, and obtains a lost region as a region to be lost when the determination object image is deleted on the basis of deformation information between the reference image and the determination object image and the unnecessary region, and determines the deletion propriety of the determination object image on the basis of the obtained lost region.COPYRIGHT: (C)2014,JPO&INPIT【課題】 変形情報を用いることで画像の削除により観察できなくなる領域の発生を抑止する画像要約処理を行い、その際に不要領域を用いることで当該画像要約処理の効率を向上させる画像処理装置、プログラム及び画像処理方法等を提供すること。【解決手段】 画像処理装置は、複数の構成画像を有する画像列を取得する画像列取得部200と、画像列の複数の構成画像の一部を削除して要約画像列を生成する画像要約処理を行う処理部100を含み、処理部100は、複数の構成画像から基準画像と判定対象画像を選択し、判定対象画像の不要領域を検出し、基準画像と判定対象画像の間の変形情報、及び不要領域に基づいて、判定対象画像を削除した場合に失われる領域である喪失領域を求め、求めた喪失領域に基づいて、判定対象画像の削除可否の判定を行う。【選択図】 図2
