Abstract
A control system of a game apparatus, such as a racing game apparatus, has a CPU for controlling a signal processor based on a program stored in a computer-readable recording medium to process three-dimensional image data for perspective projection and horizontal image distortion correction for images to be projected onto a curved projection screen. The CPU also controls an image display processor to write the processed image data into a RAM, from which the image data is supplied to an image projector to project the images onto the curved projection screen. The curved projection screen gives a game player, e.g., a racing car driver, a horizontally long panoramic view in front of the game player so that the images displayed on the curved projection screen look wide and realistic.
