Description

本発明の目的を達成するために、例えば、本発明の画像処理装置は、見開き２ページが撮像された撮像画像を取得する取得手段と、
前記撮像画像上の基準領域を取得する基準領域取得手段と、
前記撮像画像中の見開き２ページのうち前記基準領域に対応する第１のページ内の画像を、該見開き２ページにおいて後方側のページの画像として登録し、前記撮像画像中の見開き２ページのうち該第１のページとは異なる第２のページ内の画像を、該見開き２ページにおいて前方側のページの画像として登録する登録手段と
を備えることを特徴とする。 In order to achieve the object of the present invention, for example, an image processing apparatus of the present invention includes an acquisition unit that acquires a captured image obtained by capturing two spread pages;
Reference area acquisition means for acquiring a reference area on the captured image;
Among the two spread pages in the captured image, the image in the first page corresponding to the reference area is registered as an image of the rear page in the two spread pages, and among the two spread pages in the captured image The image processing apparatus includes registration means for registering an image in a second page different from the first page as an image of a front page in the two spread pages .

ステップＳ１２１５では、ＣＰＵ２０４は原稿判定部１０６として機能し、ステップＳ１２１２で歪み補正処理を行った画像から一致領域を取り除いた残りの領域の枠を特定する。 In step S1215, the CPU 204 functions as the document determination unit 106, and specifies a frame of the remaining area obtained by removing the matching area from the image subjected to the distortion correction process in step S1212.
