Summary:PROBLEM TO BE SOLVED: To provide an image processing system for projecting an image with a wide angle of view, on the basis of a three-dimensional mode, an image processing method, and a program.SOLUTION: A function block 200 of the image processing system includes: receiving means 258 of receiving an input value for defining an output range; and a plane image projection unit 260 having generation means (texture mapping unit) for generating a three-dimensional model formed by pasting an image on a three-dimensional shape, determination means (parameter determination unit) for determining a position of a point of sight and an angle of view on the basis of the input value, and projection means (projection unit) for projecting the three-dimensional model from the point of sight. When the input value is in a first range, the determination means changes the angle of view preferentially to change the range of the image falling within the field of view, or changes the position of the point of sight preferentially when the input value is in a second range which is closer to wide-angle side than the first range, to change the range of the image falling within the field of view.SELECTED DRAWING: Figure 2 【課題】広画角で構成された画像を三次元モデルに基づき射影するための画像処理システム、画像処理方法およびプログラムを提供する。【解決手段】本画像処理システムの機能ブロック２００は、出力範囲を規定する入力値を受け付ける受付手段２５８と、対象画像を三次元形状に貼り付けた三次元モデルを生成する生成手段（テクスチャマッピング部）と、入力値に基づき、視点の位置および視野角を決定する決定手段（パラメータ決定部）と、視点から三次元モデルを射影する射影手段（射影部）とを有する平面画像投映部２６０を含む。上記決定手段は、入力値が、第１の範囲にある場合は、視野角を優先的に変化させることで対象画像の視野内に入る範囲を変化させ、入力値が、第１の範囲より広視野側にある第２の範囲にある場合は、視点の位置を優先的に変化させることで視野内に入る範囲を変化させる。【選択図】図２
