Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is designed to project images from two image sources for the right eye and the left eye onto a lenticular screen, and to project each projected image on the lenticular screen into the right eye and the left eye to provide parallax. More specifically, the present invention relates to a parallax adjusting device for a game machine that allows a player to adjust parallax by themselves.

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. 8A and 8B are views showing an example of a game machine capable of stereoscopic viewing. FIG. 8A is a side view and FIG. 8B 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 guided onto the lenticular screen 21. The players 26 and 27 can stereoscopically view the image by sitting at a predetermined position on the lenticular screen 21 and viewing the projected image on the screen.

FIG. 9 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, a perspective image is generated and stereoscopic viewing is possible.

[0004]

By the way, the above-mentioned game machine does not see an actual stereoscopic image but stereoscopically sees an image formed by the device, so that it is compared with a normal plane screen game machine. Players are very tired. Therefore,
In order to eliminate tiredness as much as possible, a certain amount of time has passed since the game started, and a pause is compulsorily made, and if the eyes are tired, a warning for advancing the interruption is generated. Therefore, the player cannot play continuously for a certain time or longer. Further, since the parallax is predetermined, it is impossible to play with a stereoscopic effect desired by the player.

An object of the present invention is to provide a parallax adjusting device for a game machine which can minimize the fatigue of the player, thereby enabling continuous play and selecting the degree of stereoscopic effect according to the taste of the player. To provide.

[0006]

In order to achieve the above-mentioned object, a parallax adjusting device for a game machine according to the present invention for experiencing stereoscopic vision projects images from two image sources for a right eye and a left eye onto a lenticular screen. In a game machine in which each of the projected images on the lenticular screen is made incident on the right eye and the left eye to give a parallax, an operation unit for adjusting parallax is provided, and the lenticular screen is operated by the operation of the operation unit. The degree of parallax can be adjusted by changing the two images for the right eye and the left eye projected above to images with different viewpoints from the right direction and the left direction, respectively. Further, in the above-mentioned configuration according to the present invention, the degree of parallax has a plurality of modes of a stereoscopic off mode and a stereoscopic mode of each intensity level, and the degree of parallax can be selected stepwise by operating the operation unit. There is. Further, according to the present invention, when the mode is selected by the operation of the operation unit in the above configuration, the selected mode is displayed on a part of the screen.

[0007]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a plan view showing a control panel portion of a game machine to which a parallax adjusting device according to the present invention can be applied to experience stereoscopic vision. FIG. 2 is a rear view of the game machine of FIG. The upper side of FIG. 1 is the screen side, and two players can sit on the left and right seats 4a and 4b. Play levers 3a and 3b are arranged in front of the seats 4a and 4b. Operation buttons 1 and 2 for adjusting parallax are installed between the levers 3a and 3b. The player can adjust the parallax by pressing the operation button 1 or 2 before the game starts or during the play.

FIG. 3 is a diagram for explaining a method of operating the operation buttons. At the start of the game, it is in 3D standard mode, and by pressing operation button 1 or 2
You can change the mode of. When the operation button 1 is pressed once, the mode becomes the 3D weak mode. Press it once more to enter 3D off mode. On the contrary, if you press the operation button 2 once, 3
It becomes D strong mode. If you keep pressing it continuously, the mode will switch at regular intervals.

FIG. 4 is a diagram showing an example of a screen display when a mode is selected with the operation button. The selected mode is displayed at the top of the lenticular screen 5. For example, if 3D weak is selected, "-3D weak-" is displayed, and the player can recognize which parallax of stereoscopic vision is to be performed. After this display lights for a certain period of time,
It is supposed to disappear.

FIG. 5 is a diagram showing an example of a projected image of each mode formed on the screen. In FIG. 5, in the 3D off mode, the images projected from the left and right projectors are the same images viewed from the same position, and the left and right eyes have no parallax, so that the images look planar. In the 3D weak mode, the projected image viewed by the right eye is an image when viewed at a position slightly displaced to the right, and this image is projected on the screen in a form slightly displaced to the left. Similarly, the projected image on the screen viewed by the left eye is projected with a slight shift to the right. Therefore, the position where the left and right lines of sight intersect moves slightly to the player side from the screen, and the moved amount appears to float.

In the 3D standard mode, each projected image is an image when viewed at a position that is standardly shifted in the left-right direction, is a preset projected image, and a standard stereoscopic image can be viewed. . In the 3D strong mode, each projected image is an image when viewed at a position that is considerably deviated in the left-right direction, and is a stereoscopic image that is extremely projected to the player side.

(S702).

When an operation signal for mode switching is input to the button detection unit 17, the button detection unit 17 first determines whether or not it is the off mode (S703). If it is not the off mode, it is determined whether or not it is the weak mode (S704). If it is not the weak mode, it is determined whether or not it is the standard mode (S70).
