Method of converting two-dimensional images into three-dimensional images in video game set

Claim 2

The method according to claim 1, further comprising the steps of, when a sprite image so displayed as to be positioned on a monitor surface out of sprite images is taken as a reference sprite image, producing a left eye sprite image whose phase is not shifted and a right eye sprite image whose phase is shifted leftward with respect to the reference sprite image, calculating, with respect to the sprite images assigned higher priorities for display than that assigned to the reference sprite image, the amount of phase shift so that the higher the priority for display assigned to one of the sprite images is, the larger the amount of phase shift of the sprite image is, and producing a left eye sprite image whose phase is shifted rightward and a right eye sprite image whose phase is shifted leftward on the basis of the calculated amount of phase shift for each image, and calculating, with respect to the sprite images assigned lower priorities for display than that assigned to the reference sprite image, the amount of phase shift so that the higher the priority for display assigned to one of the sprite images is, the smaller the amount of phase shift of the sprite image is, and producing a left eye sprite image whose phase is shifted leftward and a right eye sprite image whose phase is shifted rightward on the basis of the calculated amount of phase shift for each image.
