Patent ID: 7314414

Claim:
A game apparatus that uses an ultraviolet ray to affect a game, comprising: a game program storage which stores a game program; at least one operating control which inputs operating information from a player; ultraviolet ray value detector which detects an ultraviolet ray value; correcting-data storage which stores correcting data for correcting the ultraviolet ray value; an ultraviolet ray value correcting programmed logic circuitry which corrects the ultraviolet ray value detected by said ultraviolet ray value detector, based on said correcting data; and a game process programmed logic circuitry that executes the game, based on the game program stored in said game program storage and the operating information input by said at least one operating control, and uses the ultraviolet ray value, corrected by said ultraviolet ray value correcting programmed logic circuitry, to affect the game.
