A storage unit stores a position of an object, a viewpoint position, a sight line direction, a position of an indication sign in a screen and a position of an attention area in the screen. An input receiving position receives an instruction input to change the viewpoint. A generation unit generates an image of the virtual space viewed from the viewpoint in the sight line direction. A display unit displays the generated image. A distance calculation unit calculates a distance between an object displayed in the attention area and the viewpoint. A move calculation unit calculates a moving direction and a moving distance of the viewpoint. A correction unit corrects the moving distance so that the corrected moving distance monotonically decreases relative to the calculated distance. An update unit moves the viewpoint in the calculated direction by the corrected moving distance. |
