Image display device, a game program, a game control method

A viewer of the image display apparatus is actually an image display device capable of obtaining a feeling as if can perform as if directly operating on the stereo image does not exist, the game program, provides a game control method to it. A game apparatus 1 as an image display apparatus, image display means for displaying a parallax image on the liquid crystal monitor 3a (ImL, ImR), virtual stereoscopic image VR recognized by a viewer of the parallax images (player) provided with the first coordinate calculating means for calculating spatial coordinates of the second coordinate calculating means for calculating spatial coordinates of the operation body 30 is a viewer's operation target. The game apparatus 1 also when the distance between the spatial coordinates of at least one point of the three-dimensional image calculated, the calculated spatial coordinates of at least one point of the operating body 30 is equal to or less than a predetermined threshold parallax comprising an image or an event generating means for generating a predetermined event with at least one of the change in the image on the liquid crystal monitor 3a other than the parallax images. .FIELD 1
