A number of objects, of which statuses such as position and posture can be periodically updated by having deterioration of smoothness of a display image inconspicuous even a visual point position and a visual line direction change as needed in a virtual three-dimensional space, is increased. An image processor generates and displays a display image for displaying the virtual three-dimensional space, in which a visual point and a plurality of objects to be displayed are arranged, from the visual point. The image processor includes an object selecting section (66), which calculates each display size of the objects in the display image, and selects a part of the objects based on the calculated display size of the objects; and a status updating section (68) which updates each status in the virtual three-dimensional space of the object selected by the object selecting section (66) at time intervals different from those of each status in the virtual three-dimensional space of other objects. |
