Winning information, payout information, and the like are sent to the CPU 101 from the P machine control section that manages the state of the pachinko machine. The CPU 101 outputs display control information and the like for drawing a sprite image with polygons based on these pieces of information.

First, the polygon information generation unit 102
Based on the display control information sent from U101, arithmetic processing for arranging each polygon constituting the object in the world coordinate system (three-dimensional space coordinates) is performed. Next, a process of converting polygons on the world coordinate system into polygons on the viewpoint coordinate system viewed from a single viewpoint is performed. Then, polygon information (vertex coordinates and the like) is generated by converting each polygon on the viewpoint coordinate system into a polygon on the screen coordinate system.

The drawing means 103 performs processing for drawing pixels in the polygon based on the polygon information, and outputs image information (color code) represented by a color code.
Generate This drawing process uses, for example, a Z buffer method using a Z value that is a distance from the viewpoint of the polygon. Then, from the obtained image information on the polygon, left-eye image information (color code) and left-eye image information (color code) having different parallaxes are generated. At this time, the amount of parallax is determined based on the Z value that is the distance from the viewpoint of the polygon. That is, since the Z value indicates the position of the polygon in the front-back direction, when displaying the polygon in front of the monitor surface, the parallax amount is larger for the polygon on the front side.

Specifically, the left-eye image information and the left-eye image information having different parallaxes generate two pieces of image information having phases shifted from each other in the horizontal direction based on the image information obtained by the Z-buffer method. It is obtained by doing. In this case, the shift amount of the horizontal phase corresponds to the parallax amount.

The left-eye image information and the right-eye image information output from the drawing means 103 are stored in a lookup table 1
04. The look-up table 104 converts the transmitted information (color code) into a corresponding video signal (R, G, B signal). The video signals (R, G, B signals) output from the lookup table 104 are:
The signal is converted into an analog signal by the DA converter 105.

The display device 106 includes a display control circuit that generates a stereoscopic image based on the left-eye video signal and the right-eye video signal, and a three-dimensional display. The three-dimensional display displays the three-dimensional image generated by the display control circuit. Is done.
