It is an object of the present invention to make a game player comfortably watch moving pictures when a camera's line-of-sight tracks a moving object. In a program of the present invention, a control unit recognizes point-of-sight position data for indicating a position of a camera's point-of-sight. Then, the control unit recognizes a view-frustum region and an intra-view-frustum region. Next, the control unit decides whether or not a moving object is located within the intra-view-frustum region. When the control unit decides that the moving object is located outside the intra-view-frustum region, the control unit executes processing of moving at least one of the camera's point-of-sight and a camera's point-of-target so that the moving object is located within the intra-view-frustum region. |
