First Claim
1. A game system in which two virtual game spaces, comprising a three-dimensional first game space and a two-dimensional second game space wherein the second game space corresponds to a predetermined two-dimensional plane within the first game space, and wherein the two virtual game spaces are separately displayed respectively on a first display device and a second display device, the game system comprising:
- first display control programmed logic circuitry that causes an object, contained in a first game space represented by a three-dimensional coordinate system, to be displayed on the first display;
second display control programmed logic circuitry that causes an object, contained in a second game space represented by a two-dimensional coordinate system, to be displayed on the second display; and
coordinate converting programmed logic circuitry which performs a coordinate computing process, in which three-dimensional coordinates corresponding to a location of an object in the first game space are mathematically projected onto a two-dimensional plane within the first game space that corresponds to the second game space so as to determine coordinates that are indicative of a location where a shadow of the object would occur on the two-dimensional plane when produced by a light positioned at a predetermined location within the first game space, whereinthe second display control programmed logic circuitry further displays on the second display a related image which corresponds to the object in the first game space and which is located at the determined coordinates in the second game space.

Abstract
In a game system in which two related virtual game spaces are separately displayed on a first display device and a second display device, an object, contained in a first game space represented by a three-dimensional coordinate system, is displayed on the first display device, and an object, contained in a second game space represented by a two-dimensional coordinate system, is displayed on the second display device. A coordinate conversion process is performed in which coordinates indicating a current location of the object in the first game space are mathematically projected onto a two-dimensional plane within the first game space that corresponds to the second game space, so as to determine coordinates in the second game space, that are indicative of a location where a shadow of the object would occur in the two-dimensional plane of the second game space when produced by a light source positioned at a predetermined location in the first game space.
