Summary:To appropriately perform filtering on a geometrically deformed image obtained by geometrically deforming a part of an input image.SOLUTION: An image processing apparatus that geometrically deforms a part of an input image to generate an output image, comprises: first acquisition means of acquiring the image size of the output image; second acquisition means of acquiring the size of a filter of filtering performed on the geometrically deformed image that is obtained by geometrically deforming the part of the input image; determination means of determining the image size, which is according to the size of the filter and is larger than the image size of the output image, as the image size of the geometrically deformed image; and generation means of generating a parameter indicating a position of the input image corresponding to a position of each pixel in the geometrically deformed image which is in the determined image size.SELECTED DRAWING: Figure 7 【課題】入力画像の一部を幾何変形することで得られた幾何変形画像に対して、適切にフィルタ処理を実行する。【解決手段】入力画像内の一部を幾何変形して出力画像を生成するための画像処理装置は、出力画像の画像サイズを取得する第1の取得手段と、入力画像の一部を幾何変形して得られる幾何変形画像に対して実行されるフィルタ処理のフィルタのサイズを取得する第2の取得手段と、幾何変形画像の画像サイズとして、フィルタのサイズに応じた画像サイズであって出力画像の画像サイズより大きい画像サイズに決定する決定手段と、決定された画像サイズの幾何変形画像のそれぞれの画素の位置に対応する入力画像の位置を示すパラメータを生成する生成手段と、を有する。【選択図】図7
