A character object CH 1 is first projected onto a screen plane, and a masked area is rendered as a circular area that is centered about the position of the character object CH 1 projected onto the screen plane. The obtained image data is stored in a main memory as mask data, and is used when rendering each object in a virtual game space. A transparency flag is set in advance for each of field objects OB 1 to OB 3. The field object OB 1 whose transparency flag is "1" is rendered by using the mask data, whereas the character object CH 1 and the field objects OB 2 and OB 3 whose transparency flag is "0" are rendered normally. Thus, it is possible to provide a video game device capable of displaying a particular object such as the player character so that it can always be seen, with minimum detraction from the atmosphere of the game field.
