Zusammenfassung:	The image capturing part 201 captures a ball in flight with a camera continuously. The image corresponding part 203 generates a first registered ball image obtained by making a size of a first ball image in a first capturing image captured first correspond to a size of a second ball image in a second capturing image captured second. The 3D model constructing part 204constructs a 3D model of the first registered ball image obtained by converting a camera coordinate system of the generated first registered ball image into a world coordinate system. The virtual rotating part 205 rotates virtually the constructed 3D model of the first registered ball image by using a rotation parameter estimated in advance and rotation matrix information. The registered image generating part 206 generates a second registered ball image in the camera coordinate system obtained by converting the world coordinate system of a visible surface to see from the camera in the 3D model of the first registered ball image after the rotation into the camera coordinate system. The difference calculating part 207 extracts a second compared ball image corresponding to the second registered ball image in the second ball image, and calculates a difference between the second registered ball image and the second compared ball image. The rotation parameter determining part 208 repeats the virtual rotation of the 3D model, the generation of the second registered ball image and the calculation of the difference, and determines a rotation parameter to minimize the difference as a real rotation parameter.
