Summary:To properly determine a color of an object included in a virtual viewpoint image.SOLUTION: A second image processing apparatus 40 is configured to generate a virtual viewpoint image by determining a color of an object on the basis of a method selected out of: a virtual viewpoint-dependent rendering method that determines a color on the basis of virtual viewpoint information for specifying a position of a virtual viewpoint and a line of sight direction from the virtual viewpoint, shape information for specifying a three-dimensional shape of an object, and images acquired by a plurality of imaging apparatuses; and a virtual viewpoint-independent rendering method that determines a color on the basis of shape information for specifying a three-dimensional shape of an object and color information for specifying a color corresponding to a component constituting the shape information.SELECTED DRAWING: Figure 2 【課題】 仮想視点画像に含まれるオブジェクトの色を適切に決定する。【解決手段】 第２の画像処理装置４０は、仮想視点の位置及び仮想視点からの視線方向を特定するための仮想視点情報と、オブジェクトの３次元形状を特定するための形状情報と、複数の撮像装置により取得された画像とに基づいて色を決定する仮想視点依存レンダリング方法と、オブジェクトの３次元形状を特定するための形状情報と、形状情報の構成要素に対応する色を特定する色情報とに基づいて色を決定する仮想視点非依存レンダリング方法のうち、選択された方法に基づいて、オブジェクトの色を決定して、仮想視点画像を生成する。【選択図】 図２
