FIG. 8 is a diagram for explaining the principle of the game machine.
The lenticular screen is configured by arranging a number of kamaboko lenses. The images projected on the lenticular screen from the two right-eye and left-eye liquid crystal projectors are separated into left and right by the polarizing lens action of the kamaboko lens of the lenticular screen. The image of the right-eye liquid crystal projector is incident on the right eye, and the image of the left-eye liquid crystal projector is incident on the left eye.
The parallax due to the shift between the left and right images causes a sense of perspective and enables stereoscopic viewing.
[0004]
[Problems to be solved by the invention]
By the way, the above-mentioned game machine does not look at an actual stereoscopic image but stereoscopically views an image created by the device, so that the player is more tired than an ordinary flat screen game machine, and depending on the player There are individual differences.
Therefore, if the player himself / herself has a device that can adjust the degree of the stereoscopic image, it is considered that an optimal stereoscopic image that can reduce fatigue for each player can be created. For example, there is a device that allows the player himself to change to a convergence point that is most suitable for himself, and to adjust the interval between the left and right images so that the images can be clearly seen because there is an individual difference between the eyes of both eyes. desired.

Hereinafter, embodiments of the present invention will be described 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 binocular image incident position and convergence point adjusting device according to the present invention is applied. 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 3a and 3b. Play levers 2a and 2b are arranged in front of the seats 3a and 3b. An operation button 1 for adjusting the binocular image incident position and the convergence point is installed between the levers 2a and 2b. The player can adjust the binocular image incident position and the convergence point by pressing the operation button 1 before the game starts or during play.
[0008]
FIG. 3 is a diagram for explaining each position when the convergence point and the binocular image incident position are adjusted by the operation buttons.
(A) is the case where the image is changed from the state where the image appears to protrude most with respect to the lenticular screen to a direction where the amount of appearance is small, that is, the screen direction. By pressing the operation button (A) 1a, the convergence point of 4b is changed to the arrow direction. Can be adjusted to 4a.
(B) is a case where the image is changed from the position where the image appears to protrude to the lenticular screen to the direction where it appears most popping out, and the convergence point of 4a can be moved in the direction of the arrow by pressing the operation button (B) 1b. It can be adjusted to the position.
[0009]
(C) is a case in which the distance between the incident positions on both eyes is adjusted to a direction in which the distance between the incident positions is increased from the state in which the distance is adjusted to a small distance. By pressing the operation button (C) 1c, The interval can be increased as 6a, 7a.
(D) is a case where the distance between the incident positions on both eyes is adjusted to a large distance from the adjusted distance to a direction in which the distance between the incident positions becomes smaller. By pressing the operation button (D) 1d, 6a and 7a are displayed. Can be widened like 6b and 7b.
When each button is continuously pressed, the button moves by a certain amount until reaching a position where it does not change.
[0010]
FIG. 4 is a circuit block diagram showing an embodiment of a circuit of a game machine to which the binocular image incident position and convergence point adjusting device according to the present invention is applied.
In this figure, the printed circuit board (PCB) for the right eye is the same as the PCB for the left eye, and is omitted.
The input / output circuit 15 is connected to the input / output circuit for the right eye, and the left-eye video and the right-eye video are synchronized.
The ROM 14 stores a program for controlling the entire game, and the RAM 13 serves as a work area for the CPU 11.
An input signal from the operation unit 9 is input to the CPU 11 via the input control circuit 10. The CPU 11 performs an operation based on the program and the input signal, and sends information for creating a three-dimensional image to the 3D image generation circuit 12.
[0011]
The 3D image generation circuit 12 includes a three-dimensional arithmetic circuit that converts the three-dimensional coordinates of the polygon data into a viewpoint coordinate system having the player as the origin, a perspective conversion circuit that converts the three-dimensional coordinates into two-dimensional coordinates on the screen, and perspective conversion. This is composed of a clipping circuit that determines whether or not the polygons entered the screen, a sorting circuit that sorts each polygon based on the Z representative value, etc. The generated 3D image signal of the stereoscopic off mode, the stereoscopic weak mode, and the stereoscopic strong mode is generated. The left-eye projector 8 projects this image on the lenticular screen 5.
[0012]
FIG. 5 is a diagram showing an embodiment of a functional block of the CPU.
When the CPU 11 for the left eye detects a signal indicating a change in the convergence point, the game processing unit 16 that processes the game by the input of each operation signal, the button detection unit 17 that detects the input of the operation signal, and the button detection unit 17 detect the signal. When the convergence point control unit 18 and the button detection unit 17 that perform video processing so as to shift the convergence point back and forth by an amount according to the signal detect a signal indicating a change in the binocular video input position, only the distance according to the signal is obtained. A functional block of a binocular viewpoint control unit 19 that processes a left-eye image among images incident on both eyes so as to be changed is provided. The CPU of the PCB for the right eye has a similar functional block.
[0013]
FIG. 6 is a flowchart for explaining the adjustment operation according to the present invention.
At the start of the game, the CPU 11 is processing the game by the game processing unit 16 (step (hereinafter referred to as “S”) 601), and a signal for changing the convergence point and the binocular video input position by the button detection unit 17. Whether or not a signal for changing is input is watched.
When an operation signal is input to the button detection unit 17, the button detection unit 17 first determines whether or not the signal is from the A button that decreases the convergence point (S602). If it is not the signal from the A button, it is determined whether or not the signal is from the B button for increasing the convergence point (S603). If it is not the signal from the B button, it is next determined whether or not the signal is from the C button which increases the distance between the binocular video input positions (S604).
[0014]
If it is not a signal from the C button, it is determined that the signal is for reducing the distance between the binocular video input positions. The convergence point control unit 18 performs either a process of reducing (distracting) or increasing (approaching) the convergence point (S605, S606). The binocular viewpoint control unit 19 performs either a process of widening or narrowing the distance of the binocular video input position (S607, S608).
[0015]
【The invention's effect】
As described above, the present invention is provided with an operation unit that adjusts the binocular image input position and the convergence point, and the convergence point of the two images for the right eye and the left eye projected on the lenticular screen by the operation of the operation unit. And the video incident position can be adjusted for both eyes of the player, so that the player himself changes to the convergence point that is most suitable for himself and the video is clearly visible. There is an effect that an optimum stereoscopic image can be created by changing the position.
