To provide an image processing technology reducing a burden referring to an image process and capable of easily and naturally representing moving images in a virtual three-dimensional space.

A scroll control part 2500a reads out speed data housed in a memory means 2510a to scroll each background block disposed in the virtual three-dimensional space based on the speed data read out. An axis rotation controlling part 2500b reads out axis rotation data housed in a memory means 2510b to rotate each background block disposed in the three-dimensional space based on the axis rotation data read out. Concretely, while rotating the background block around an X axis, the running course of a moving object is curved; and while rotating the background block around a Y axis, the course is tilted.
