Abstract

A display driver instructed by a host computer to perform a display operation uses an object analyzer to determine whether the file of an object to be displayed possesses three-dimensional image data. If the file possesses three-dimensional image data, then the display drive instructs a screen controller to present a three-dimensional display. In response, the screen controller uses an image painting unit and a checkered mask-pattern painting unit to present a three-dimensional display in a display area of the file on a stereoscopic display screen.
