2. Description of the Related Art Game consoles that allow a player to experience stereoscopic vision in order to give the game a realistic feeling and power are becoming popular. 5A and 5B are views showing an example of a game machine capable of stereoscopic viewing, where FIG. 5A is a side view and FIG. 5B is a top view. A right-eye projector 24 and a left-eye projector 25 are arranged in the game machine, and mirrors 22 and 2 are provided.
The image projected from the projectors 24 and 25 by 3 is projected on the lenticular screen 21. Players 26 and 27 have a lenticular screen 21
On the other hand, the image can be stereoscopically viewed by sitting at a predetermined position, that is, a position where the heads (both eyes) are fixed so as to be a predetermined position, and viewing the image on the projected screen.

FIG. 6 is a diagram for explaining the principle of the game machine. The lenticular screen is configured by arranging a large number of kamaboko type lenses. Images projected from the two right-eye and left-eye liquid crystal projectors onto the lenticular screen are separated into left and right by the polarizing lens action of the kamaboko lens of the lenticular screen. The image of the liquid crystal projector for the right eye is incident on the right eye, and the image of the liquid crystal projector for the left eye is incident on the left eye. Due to the parallax caused by the displacement of the left and right images, the image has a perspective and stereoscopic viewing is possible.

[0004]

In the above game machine, in order for the player to experience a stereoscopic image, the image output from the projector, the lenticular screen, and the player's head position (both eye positions) have a fixed relationship. It is necessary. By the way, the position of the lenticular screen may be slightly deviated during transportation or installation of the game machine. Figure 7 if the screen is in the correct position
As shown in (a), the player can experience a stereoscopic effect. However, if the screen is slightly deviated,
As shown in (b), the player has to shift the position on which his head is placed considerably, and it is difficult to maintain such a head position during the game. An object of the present invention is to provide a stereoscopic image display game machine that can be easily adjusted when a slight shift occurs on the screen.

[0005]

In order to achieve the above object, images of two image sources for the right eye and the left eye according to the present invention are projected on a lenticular screen, and each projected image on the lenticular screen is projected to the right eye and the left eye. In a game machine in which stereoscopic vision can be experienced by making each incident and providing parallax, the right-eye and left-eye image generation circuit means have image generation units capable of producing both right-eye and left-eye images, respectively. It is configured such that the images produced by the two image sources by operation are reversed for the right eye and the left eye and output.

Embodiments of the present invention will be described below in detail with reference to the drawings. 1A and 1B are schematic diagrams for explaining a stereoscopic image display game machine capable of exchanging left and right images according to the present invention. FIG. 1A is a side view and FIG. 1B is a plan view of a head fixing portion. There is. The player 3 sits on the seat 6 of the game machine 1, hits the head 3a against the head fixing portion 5, and positions both eyes. The player 3 can see a stereoscopic image by seeing the images projected from the projectors for the right and left eyes (not shown) on the lenticular screen 2.

The stereoscopic image cannot be clearly seen if it is displaced in either direction of arrow A with respect to the proper position. Further, if the lenticular screen 2 is slightly displaced in the left-right direction, the player cannot see stereoscopically unless he / she moves his / her body halfway to the left or right. Therefore, a button (external operation unit) 7 for exchanging left and right images is provided on the lower surface of the operation unit of the game machine. If the lenticular lens is misaligned, the left and right images are exchanged by the installer at the time of adjustment immediately after the game machine is installed.

FIG. 2 is a circuit block diagram showing an embodiment of a circuit of a stereoscopic image display game machine capable of exchanging left and right images according to the present invention. This figure shows only the left-eye printed circuit board (PCB) which is the image generation circuit means,
Since the PCB for the right eye is the same as the PCB for the left eye, it is omitted. The input / output circuit 15 is connected to the input / output circuit of the right-eye PCB so that the left-eye and right-eye images are synchronized. The ROM 14 stores programs for controlling the entire game, and the RAM 13 serves as a work area for the CPU 11. The input signal from the operation unit 9 is input to the input control circuit 1
It is input to the CPU 11 via 0. The CPU 11 performs calculation based on the program and the input signal, and sends information for forming a three-dimensional image to the 3D image generation circuit 12.

The above-mentioned button 7 is connected to the left and right eye PCBs as a part of the operating portion 9. When this button 7 is pressed, the signal is transmitted via the CPU 11 and the input / output circuit 15 to the right eye PCB. Also sent to the CPU. The 3D image generation circuit 12 is a three-dimensional arithmetic circuit that converts three-dimensional coordinates of polygon data into a viewpoint coordinate system having a player as an origin, a perspective conversion circuit that converts the three-dimensional coordinates into two-dimensional coordinates on a screen, and perspective conversion. The 3D video signal is generated by a clipping circuit that determines whether or not the formed polygons enter the screen, a sorting circuit that rearranges each polygon based on the Z representative value, and the like. Left eye projector 16
Projects this image on the lenticular screen 2.

FIG. 3 is a diagram showing an embodiment of the functional blocks of the CPU. The left-eye and right-eye CPUs are respectively shown in (a) and (b). The left-eye CPU 11 and the right-eye CPU 17 have image generation units 18 and 20 and button detection units 19 and 21 that can generate both right-eye and left-eye images. When the operation signal is input, the button detection units 19 and 21 determine whether the signal is from the button 7.

FIG. 4 is a flow chart for explaining the operation of left and right image exchange according to the present invention. When the game starts, the CPU 11 of the left-eye PCB first generates the left-eye image by the image generation unit 18 (step (hereinafter referred to as "S") 401). Next, the button detector 1
It is determined whether or not 9 detects the signal input from the button 7 (S402), and when the signal from the button 7 is detected, the image generation unit 18 generates the image for the right eye (S403). ). On the other hand, the CPU 17 of the right-eye PCB generates a left-eye image when the signal from the button 7 is detected by the same operation (S406).
