Picture processing device, picture processing method, and game device and storage medium using the same

A picture processing device for expressing display objects by composing each display object with a plurality of elements, comprising:

• picture processing means for changing the number of said elements according to a distance between a viewpoint and one of said display objects and for projecting the display object in a three-dimensional space onto a plane on the basis of said viewpoint, wherein said picture processing means decreases the number of said elements as said display object moves farther away from said viewpoint;
• and
• element number changing means for changing the number of said elements, which compose said display object when attributes of the display object change, wherein when the display object is at a distance far from said viewpoint and the display object is a focus of attention, the number of polygons of the display object is increased, and wherein said element number changing means performs its processing when it determines that said display object has become an object of operation and, therefore, the attributes of said display object have changed, said element number changing means comprising:
• means for determining whether the number of said elements of said display object should be increased;
• attribute determining means for determining whether said display object has become the object of operation;
• and
• element number calculating means for calculating an increase in the number of elements based on the determination results of said attribute determining means,
• wherein said display objects include a plurality of first display objects and a second display object having some relationship with said plurality of first display objects in a three-dimensional space, and when said plurality of first display objects compete with each other for control over said second display object, said attribute determining means determines that one of said plurality of first display objects which has gained control over said second display object is the object of operation.
