Summary:To provide an image processing program, an image processing apparatus, and an image processing method for dynamically changing a highlight area appearing on the hair of an illustration-like three-dimensional character.SOLUTION: In an image processing system having an image processing apparatus, a motion capture device, a virtual camera operation device, and a display, the image processing apparatus generates an image obtained by photographing, with a virtual camera, a three-dimensional character in a three-dimensional virtual space, and the image processing apparatus executes processing of projecting a highlight image drawn on a cylinder on the head of the three-dimensional character through cylindrical mapping using a cylinder surrounding the head and following the movement of the head, and processing of moving the cylinder in the vertical direction following the movement in the vertical direction of the virtual camera. The processing of moving the cylinder includes processing of adjusting the amount of movement in the vertical direction of the cylinder to cause the projected highlight image to fall within a predetermined range of the head.SELECTED DRAWING: Figure 4 【課題】イラスト調の3次元キャラクターの髪に現れるハイライト領域を動的に変化させる画像処理プログラム、画像処理装置及び画像処理方法を提供する。【解決手段】画像処理装置と、モーションキャプチャ装置と、仮想カメラ操作装置と、表示装置と、を有する画像処理システムにおいて、3次元仮想空間において3次元キャラクターを仮想カメラにより撮影して得られた画像を生成するための画像処理装置は、3次元キャラクターの頭部の周りを囲むとともに頭部の動きに追従する円筒を用いる円筒マッピングにより、円筒に描画されたハイライト画像を前記頭部に投影する処理と、仮想カメラの上下方向の移動に追従して円筒を上下方向に移動させる処理と、を実行する。移動させる処理は、投影されるハイライト画像を頭部の所定範囲内に収めるように、円筒の上下方向の移動量を調整する処理を含む。【選択図】図4
