  • Patent number: 6917371
    Abstract: It is an object of the present invention to provide special effects which will make a video game more realistic. When a virtual light source exists in a three-dimensional virtual space, if a light from the light source extends toward a camera, a flare is generated on a screen because of incidence of the ray of light into a camera lens, thereby forming a dazzling picture in accordance with the state of backlight.
    Type: Grant

  • Patent number: 6417854
    Abstract: The image processing system comprises means for preparing a plurality of textures for providing to at least one first texture thereof a background image, in which a movable object is either in a stationary or low-speed state and means for providing to at least one of the remaining second textures a background image of when a movable object is in a low-speed or faster state of travel and for mapping to a screen in accordance with the state of themovable object the second texture in addition to the first texture.

  • Patent number: 6149519
    Abstract: An electronic game device comprises a game implementing module (30) for implementing a game; a storing module (36) for storing game results for each player; a calculating module (34) for (i) reading out a game result of the player stored in the storing module, (ii) adding the game result achieved in the game to the game result read out from the storing module, and (iii) newly storing this sum value in the storing module; and a display module for displaying the newly stored game result (13). The game device may also comprise a characteristics value storing module for storing characteristics values relating to the output device for each of the identification symbols; a reading module for reading out characteristics values corresponding to an identification symbol input by a player from the characteristics value storing module; and setting module for setting the characteristics of the output device on the basis of the characteristics values thus read out.

  • Patent number: 5971853
    Abstract: A direction control method and apparatus control the direction of a traveling object on a monitor, for example, in a video game device. An object having, for example, two elements to be directionally controlled with each of the elements being controllable in a rotational direction is displayed along with its background in a traveling state on a monitor. The object includes, for example, a war tank (31) used in a war game of a game device. The two elements to be directionally controlled includes a body (32) and a sight (33) of the tank (31). A target angle .theta. is designated by a single direction input unit 20(A) for the vehicle body (32) and the sight (33). The rotational direction of the sight (33) is controlled on the basis of the target angle .theta.. The rotational angle of the vehicle body (32) is controlled following the sight (33) on the basis of the traveling velocity of the tank (31) and the rotational angle Ya of the sight (33).
