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]

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]
