Abstract
A system two dimensional image processing comprises an image display , a central processing unit , memories , a program processing section which executes a game program which moves a moving object in a virtual three-dimensional space in which three-dimensional objects are arranged, and an operation section which accepts speed data on the moving objects in the virtual three-dimensional space and sends the data to the program processing unit. The operation section sends moving-object speed data to a perspective conversion unit . The perspective conversion unit makes the distance between a viewpoint and a projection screen variable according to the relative speed of the moving object. As the effective visual area on the projection screen becomes smaller, the range of the virtual three-dimensional space displayed in the effective visual area becomes larger. This makes the view field angle to the projection screen variable according to the movement speed of the moving object.
