Abstract To generate a display image of which an uncomfortable feeling is little with respect to a display system for displaying an image on a wide-field display part.SOLUTION: The display system including first acquisition means for acquiring a photographing field angle when an input image is photographed and a display part includes second acquisition means for acquiring display system information indicating a display angle which is a prospective angle when the display part is viewed from a viewpoint position, setting means for setting a projection surface in a virtual space, calculation means for calculating a parameter on the basis of the photographing field angle and the display angle, and generation means for generating the display image displayed on the display part by using a correspondence relation between the projection surface in the virtual space and the display part. The generation means calculates a position corresponding to a position in the display part on the projection surface by using the parameter and renders the pixel value of the calculated position on the basis of the input image, to generate the display image.SELECTED DRAWING: Figure 2 【課題】 広視野な表示部に画像を表示する表示システムに対して、違和感の少ない表示画像を生成する。【解決手段】 入力画像を撮影したときの撮影画角を取得する第1の取得手段と、表示部を含む表示システムにおいて、視点位置から前記表示部を鑑賞した時の見込み角である表示角を示す表示システム情報を取得する第2の取得手段と、仮想空間に投影面を設定する設定手段と、前記撮影画角と前記表示角とに基づいてパラメータを算出する算出手段と、前記仮想空間における前記投影面と前記表示部との対応関係を用いて、前記表示部に表示するための表示画像を生成する生成手段とを有し、前記生成手段は、前記パラメータを用いて前記表示部における位置が前記投影面において対応する位置を算出し、前記算出した位置の画素値を前記入力画像に基づいてレンダリングすることで、前記表示画像を生成する。【選択図】 図2
