FIG. 33 is a diagram showing the display of a corrected image on the game machine, FIG. 34 is a diagram showing the display of a normal image, and FIG. 35 is set on the game machine. It is a figure for demonstrating an image correction parameter.

When a normal image as shown in FIG. 34A is projected from the projector 31 (FIG. 7), the screen 121
Due to the curvature of the projected image 12, the distance from the reference viewpoint of the player 300 on the game machine front play area 130 is
Since the upper part and the lower part of 4 are different from each other, an image as shown in FIG. 34 (b) is captured by the eyes of the player 300.

On the other hand, in this game machine, the image projected from the projector 31 is corrected before projection as shown in FIG. 33 (a).
An image without distortion as shown in (b) will be seen by the player 300. Furthermore, when the projection image 124 is projected on the lower part of the screen 121 (corresponding to the dotted line in FIG. 7) and when it is projected on the upper part (corresponding to the solid line in FIG. 7), the upper part of the projection image 124 from the reference viewpoint, Since the difference in the distance to the bottom is different, the degree of correction differs depending on the rotation angle of the mirror.

In this image display processing, an image including a display object having a 3D shape in the game space, which is captured by a virtual camera (virtual viewpoint) having a rectangular field of view,
According to the rotation angle of the mirror, the lower end of the image is corrected so as to be tilted so as to approach the virtual camera, and the corrected image is projected from the projector 31.

As shown in FIG. 31, the image processing unit 410 for displaying an image with these corrections makes a line of sight according to the object position data 421 (data indicating the position of the shooting target in the game space) and the like. A line-of-sight elevation angle setting unit 4101 for setting an elevation angle (an angle at which the line of sight is tilted upward with respect to the horizontal plane, EYE_R shown in FIG. 35 described later) and a rotation angle of the mirror are specified according to the line-of-sight elevation angle, and the stepping motor 41 is set.
And the image correction table 422 (with respect to the line-of-sight elevation angle EYE_R, the tilt angle CAM_R of the virtual camera and the angle CAM that specifies the upper end of the image).

M_FB can be designated, and these correspondences are held in the image correction table 422.

In this game machine, the estimated gaze position VIEW_P is set in accordance with the distance between the player and the dinosaur, and the part of the dinosaur that attacks the player when approaching. As shown in FIG. 35 (a), this gaze assumed position VI
According to EW_P, a line-of-sight elevation angle EYE_R, which is an angle between the straight line q ₀ from the virtual viewpoint position EYE_P to the gaze assumed position VIEW_P and the horizontal line (reference line), is determined.

Subsequently, as shown in FIG. 35B, the position, the tilt angle, the projection angle of view and the mirror 43 of the projector 31.
, The mirror rotation angle MIRROR_R is determined so that the upward angle of view EYE_FU of the virtual camera and the downward angle of view EYE_FD are equal to each other with the line-of-sight elevation angle EYE_R as the center, and the upper end SCREE of the projected image is determined.
Find N_U, bottom SCREEN_D. (The virtual camera has a rectangular imaging range, and the upper end SCREEN_U and the lower end SCREEN_D correspond to the vertical angle of view of the virtual camera, but regarding the horizontal angle of view, EYE_
It is appropriately calculated from the distance from P to SCREEN_D and the width of the projected image. ) As shown in FIG.
EEN_U, the straight line q ₃ through the projected image lower SCREEN_D, obtain the intersection of the perpendicular q ₄ from the virtual viewpoint position EYE_P to the straight line q ₃ as CAM_VP, the angle (elevation angle) between the straight line q ₄ and the horizontal line, Inclination angle C of virtual camera

Also, the angle between the straight line q ₄ and the straight line q ₁ that determine the position of the upper end of the projected image is CAM_FT, and the angle between the straight line q ₁ and the straight line q ₂ that determines the position of the lower end of the projected image (along with CAM_FT). Be CAM_FB.

By the procedure as described above, the virtual camera tilt angle CAM_ which is an image correction parameter corresponding to the line-of-sight elevation angle EYE_P (and the mirror rotation angle MIRROR_R set accordingly) set during the game progress.
R, CAM_FT, and CAM_FB will be calculated. Here, CA calculated and increased / decreased for partial adjustment
It is assumed that M_R, CAM_FT, and CAM_FB are associated with the line-of-sight elevation angle EYE_R in the image correction table 422, but the rotation angle MIRR of the mirror
These correction parameters can be associated with OR_R.

In the image display process using these image correction parameters, as shown in FIG. 32, first, the line of sight is determined (according to the position of the dinosaur with respect to the virtual viewpoint, the part of the dinosaur that causes an attack when approaching, etc.). The elevation angle is the line-of-sight elevation angle setting unit 41
01 (ST991), mirror tilt control unit 4
At 102, the mirror rotation angle according to the line-of-sight elevation angle is designated (ST992), the stepping motor 41 is controlled, and the mirror 43 is rotated (ST993).

Subsequently, the image generation instructing section 4104 sets the image correction parameter (CAM) for the set line-of-sight elevation angle.
_R, CAM_FT, CAM_FB, etc.) is designated (ST994), the drawing control unit 101 is instructed to draw an image captured from the virtual viewpoint based on these image correction parameters (ST995), and the process is returned. In response to the drawing instruction, the drawing control unit 101 (3
(Dimension) Data regarding polygons in the game space is calculated to generate image data corresponding to a 2D image inclined with respect to the line of sight EYE_R, and the image data is written into the frame buffer 102, and the frame buffer 10
An image is projected on the screen 121 according to the image data on the screen 2.

According to this image display processing, the image is appropriately corrected in accordance with the position of the vertically curved portion on the screen, and the player can see the image without distortion while shooting the video game. You will be able to enjoy it.

The overall structure of the shooting video game machine and the effects provided by the structure can be summarized as follows.

This shooting video game machine allows a player to play a game while displaying an image captured from a virtual viewpoint (virtual camera) whose position in the game space corresponds to the reference viewpoint position of the player. In a game machine, an image projected from a projector through a mirror is displayed on a part of the screen that curves continuously from the lower part in front of the reference viewpoint position to the upper part in the upper part of the reference viewpoint position. The mirror is rotated so as to move at least in the up-and-down direction corresponding to.

According to this game machine, the line of sight of the player is moved in the vertical direction as the game progresses, so that the player can enjoy a novel game that has never existed before.
It can be said that these have a simple configuration. Further, since the screen is curved in the inner surface of the cylinder, the projection distance is kept substantially constant, and the size and focus of the projected image are kept substantially constant.

In particular, the screen may be curved so that the distance from the reference viewpoint position to the upper portion is smaller than the distance from the reference viewpoint position to the lower portion. It is possible to create a unique sense of urgency because it is felt so close.

Further, the gun unit causes the player to virtually shoot a dinosaur which is displayed on the screen and corresponds to the size of the screen when approaching, and the dinosaur causes a virtual attack on the player. By displaying the parts such as the mouth, arms, and legs that are about to be displayed on the screen, the player can enjoy the shooting game that effectively produces a novel and unique sense of tension.

Also, a flying dinosaur far away from the virtual viewpoint (also a dinosaur that does not fly) is displayed at the bottom of the screen, and a flying dinosaur close to the virtual viewpoint (the top of a dinosaur that does not fly) is displayed at the top of the screen. In addition, the mirror can be rotated, whereby a flying dinosaur (a dinosaur that does not fly) approaching from the distance to the vicinity of the player can be expressed with a powerful perspective.

In this game machine, the acrylic plate for protecting the rotation of the mirror and the like is provided so as to be inclined so that the virtual image is transmitted to the outside of the screen when the real image is projected on the top of the screen. Player will not be distracted by the virtual image appearing on the screen unnecessarily.

In addition, when the player detection sensor is in a predetermined detection state, the virtual viewpoint is moved so as to wrap around the dinosaur in the game space, whereby the player's left and right movements are naturally performed. It can be communicated to the game space and enrich the interest of the game.

In addition, regarding the detection of the direction of the muzzle, the configuration and effects of the shooting video game machine described above can be summarized as follows.

This shooting video game machine receives the input corresponding to the shooting on the dinosaur displayed on the screen by operating the trigger in the gun unit, and the CCD camera near the muzzle of the gun unit. , A CCD image of an imaging range corresponding to a part of the screen is generated, and at least when the trigger is pulled, images of a plurality of screen LEDs arranged on the screen so as to have a predetermined positional relationship are generated. The shooting position on the screen that substantially corresponds to the center of the imaging range is calculated from the position of the image of the identified screen LED.

According to this game machine, it is possible to identify which part on the screen is being imaged from the positional relationship of the images of the screen LEDs in the CCD image, and to calculate the shooting position. The orientation of the gun unit can be detected smoothly with respect to the screen. In particular, it can be said that the positional relationship can be easily specified by generating the two-point set table as shown in FIG. 23 and specifying the positional relationship of the screen LEDs in the CCD image.

The directions of these gun units are detected on the screen having the inner surface of the cylinder, the images to be shot are displayed on the upper and lower parts of the screen, and the images are moved up and down according to the direction of the virtual viewpoint. By doing so, it is possible to realize a shooting game full of interest and power.

Further, the configuration and effects of the shooting video game machine described above can be summarized as follows, particularly regarding image correction.

This shooting video game machine allows the player to play the game while displaying an image captured from the virtual viewpoint corresponding to the position of the game space at the reference viewpoint position of the player. The image projected from the projector via the mirror onto the part of the screen that curves continuously from the lower part in front of the reference viewpoint position to the upper part in the upper part of the reference viewpoint position, the virtual image is generated by rotating the mirror. An image that is vertically moved according to the direction of the viewpoint and is captured from the virtual viewpoint is obtained by tilting the image so that the lower side is closer to the virtual viewpoint and moved to the top of the screen. It is generated by correcting the displayed image.

In particular, the angle of this inclination can be made substantially equal to the rotation angle of the projected image on the screen.

According to this game machine, since the appropriate correction is made in accordance with the rotation of the mirror, the image projected on the screen is not distorted from the viewpoint of the player.

Further, by setting an image correction parameter for instructing the rotation of the virtual camera in accordance with the rotation of the mirror (and the line-of-sight elevation angle set during the progress of the game) in the image drawing processor, these images can be displayed. By performing the correction, effective image correction can be realized by simple control.

Further modifications of the shooting video game machine according to the above-described embodiment can be envisioned as follows.

FIG. 36 is a view for explaining rotation control of mirrors respectively associated with two areas dividing one stage in the shooting video game machine of the first modification.

In the game machine of this modification, the area 501 corresponding to the first half of the one stage and the area 50 corresponding to the second half of the stage.
2 is assumed, the small dinosaur and the flying dinosaur (normal enemy character) are shot in the first half area 501, and the large dinosaur (enemy character corresponding to the boss character) as described above is shot in the second half area 502. Let's shoot.

In the area 501 in the game space, the virtual player (virtual viewpoint) moves in the direction of arrow B ₁ at a speed designated in advance. Virtual player is in place 51
An enemy character is generated when passing 1 to 514, and the player performs virtual shooting using the gun unit 10 with respect to the display of these enemy characters. When the player detection sensors 51 to 54 react, in the game space,
A relatively small width movement is performed to the extent of avoiding the enemy character's attack to the left or right, and the mirror that determines the position of the projected image on the screen is rotated based on pre-specified data.

In the area 502 in the game space, the player detection sensors 51 to 54 detect the attack of the boss character 522 approaching the virtual player 521 in the game space.
The player operates the gun unit in response to the display of the boss character to shoot while avoiding in the direction of the arrow B ₂ or the arrow B ₃ by reacting. As if following the moving virtual player 521, the boss character 522 shows an arrow B.
₄ or move in the direction of arrow B ₅ .

Here, the player detection sensors 51 to 54
In the reaction of, a relatively large movement (a movement that goes around to the left or right of the dinosaur, such as 5 meters, 20 meters, ... with different movement widths set depending on the stage) is performed, Further, as described above, the mirror is rotated according to the distance between the boss character and the virtual viewpoint or the part where the boss character causes an attack.

In the game machine of this modification, since the movement width of the player detection sensors 51 to 54 when reacting and the method of controlling the rotation of the mirror are different, the player
It can be said that you can enjoy a more varied and timeless shooting game.

FIG. 37 shows the player 3 using the player detection sensors 51 to 54 in the shooting video game machine of the second modification.
It is a figure for demonstrating the detection of the position of 00 (at the time of two-player play of a 1P player and a 2P player).

In the game machine of this modification, when two players play,
The two virtual players in the game space are Ikuren, and both are moved in the same direction. When the 1P player (left player) is detected to move from the reference position in front of the left inner player detection sensor 52 to the front of the left outer player detection sensor 51, the player instructs the dinosaur to wrap around to the left. As, the coordinates of two virtual players are set in the game space. In addition, the 2P player (right player) is the right inner player detection sensor 5
3 from the reference position in front of the right outer player detection sensor 54
When it is detected that the virtual dinosaur has moved forward, the coordinates of the two virtual players are set in the game space as if the player had instructed the dinosaur to wrap around to the right.

In the shooting video game machine of this modification, the coordinates of the virtual players are set in accordance with the movements of the two players, so that it is possible to find a unique interest in the progress of the game in cooperation with each other. it can.

FIG. 38 is a diagram showing screen LEDs 601 to 603 installed in the shooting video game machine of the third modification.

Each of the screen LEDs 601 to 603 provided on the screen 610 of the game machine of the present modification is composed of a plurality of minute light emitting bodies, and the light emitting positions are set so that the position on the screen 610 can be specified. Is different. Since the minute light emitters are arranged so that they can be identified vertically and horizontally, the orientation of the muzzle can be accurately specified even if the gun unit is tilted horizontally.

FIG. 39 is a diagram showing image correction parameters set in the shooting video game machine of the fourth modification.

In the game machine of this modification, SCREEN_U 'is designated on the extension line of q ₁ shown in FIG. 35 (c),
A straight line q passing through SCREEN_D and SCREEN_U '
_Since CAM_VP is defined above ₅ , CAM_R will be smaller. As in these cases, CAM_R should be reduced, and conversely, CAM_R should be increased.
By appropriately adjusting and setting the size of M_R, it is possible to generate an image that is comfortable with the player's reference viewpoint position and that is more dynamic.

In addition to these, the following modifications can be envisioned.

In the shooting video game machine according to the above-described embodiment, the image from the projector is reflected by the mirror and projected on the screen. However, the projector is used while changing the inclination angle of the projector without using the mirror. Images from can be displayed directly on the screen, which can be said to be a simpler configuration.

In the shooting video game machine according to the above-mentioned embodiment, two player detection sensors are provided on the left and right, but one or three or more may be provided. When clearing each stage and proceeding to the next stage, when the player selects one of a plurality of preset routes (different game settings such as dinosaur and background), these player detection sensors are used. , The selection can be entered.

Further, the avoidance movement by the player detection sensor is not limited to the movement to the left and right, but may be the movement to lie down, or diagonally to the lower right and diagonally to the lower left. This is because, as an attack of the enemy character, when the player swings the arm or the tail in the lateral direction, the player cannot avoid the attack even if the player flies right and left. For example, if the left outer player detection sensor is turned on, it can be automatically switched depending on the scene so as to squat down and avoid the attack.

The screen of the shooting video game machine according to the above embodiment is extended above the player in the play area and installed so as to cover and cover the player. When you look at it, you will be looking up, creating a stronger sense of urgency. Further, the screen may include a linear portion other than the arcuate portion.

Further, although the inclination angle of the acrylic plate of the shooting video game machine of the above-mentioned embodiment is set to about 10 °, the virtual image is appropriately projected to the outside of the screen depending on the positions of the mirror, the projector and the screen. Can be adjusted.

In the shooting video game machine according to the above-described embodiment, the mirror rotation angle is associated with the line-of-sight elevation angle in advance when displaying an image, and the image correction parameter is stored in advance. The parameters can be sequentially calculated in the procedure shown in FIG. Further, all or a part of the screen on which the image to be corrected is projected may be vertically inclined, left or right or obliquely curved or inclined, and may be hemispherical or the like. in addition,
