Pixel data of a two-dimensional image of an object to be displayed is prepared by an image depicting circuit 1, and pixel data in a VRAM 2 is updated by the thus prepared pixel data. On the other hand, pixel data for a single screen in the VRAM 2 is read per frame cycle from the VRAM 2, and the read pixel data is supplied to a digital to analog converter section 5 through a display controller 4. Color signals R', G', and B' for actual display are prepared based on color signals R, G, and B of a pixel forming the pixel data as well as on the Z value of the object corresponding to the pixel, and the respective pixels are displayed. The most remote the object is away from a viewpoint, the more different the display colors of the object displayed by a display unit 3 become from the original colors; the display colors gradually become white. As a result, an object remote from the viewpoint can be displayed on a screen so as to be hazy in opal.
