In the state where the display range of the projection image includes two markers, the marker closer to the center of the display range of the projection image is determined, and when both markers are approximately the same distance from the center, the projection image Of the marker corresponding to the moving direction on the screen (that is, the position information from the image processing unit 410 is stored a plurality of times and compared with the position information of this time, and the marker toward the center) is determined. I am trying to do it.

FIG. 20 is a block diagram showing the configuration of the main part of the muzzle direction detecting section 401 which performs the muzzle direction detecting process in ST81 of FIG. 16, and FIG. 21 shows the detailed procedure of the muzzle direction detecting process in ST81. The flowchart shown in FIG. 22 is S.
It is a flow chart which shows the detailed procedure of the extraction processing of "L frame" in T815.

As shown in FIG. 20, the muzzle direction detector 40
1, an image pickup processing unit 4011 for fetching a CCD image (data for each pixel is stored in a predetermined area on the RAM 106) which is an image picked up by the CCD camera 13, and a predetermined data for each pixel taken A binarization processing unit 4012 that binarizes with a threshold value and stores it as bright spot data in a predetermined area on the RAM 106, or once stores the binarized data.
And a coordinate data extraction unit 401 that extracts coordinate data in which binarized bright spot data exists and organizes predetermined data.
3, and a straight line determination unit 4013 that sequentially selects a combination of 3 points from the extracted bright spot data and determines whether or not the 3 points are on a straight line and whether or not they are at substantially equal intervals.
Then, with respect to the three points existing on the straight line (main axis), the proximity determination unit 4015 that determines whether or not there is a bright spot near one of the bright spots at one end, and “L” is determined by both determination units. The intersection of the L frame specifying unit 4016 for specifying the "frame", the line-of-sight vector calculating unit 4017 for calculating the direction of the camera from the specified L frame, that is, the line-of-sight vector, and the screen 121 of the calculated line-of-sight vector (the landing position). ) Is calculated, and an intersection (H, V) calculation unit 4018 is included. In the CCD image, there are bright spots other than LEDs, that is, noise due to infrared rays contained in natural light and infrared rays contained in fluorescent lamps, discharge lamps, etc. in the case of indoors. Therefore, the straight line determination unit 4013 and the proximity determination unit 4
In 014, noise is removed by performing determination processing for all combinations.

The line-of-sight vector calculation unit 4017 and the intersection (H, V) calculation unit 4018 will be additionally described. Marker LED when the screen 121 is flat.
A to D are A (0,0), B (1,0), C (2,
0) and D (0,1), which are expanded and defined in a three-dimensional space, 0a (0,0,0), 0b (1,0,
0), 0c (2,0,0), 0d (0,1,0) or 0d (0, -1,0). On the other hand, the coordinates of each point when the defined coordinates are viewed from the CCD camera 13 are Ca (tx,
ty, tz), Cb (tx + r00, ty + r01, tz + r0
2), Cc (tx + 2 × r00, ty + 2 × r01, tz + 2 ×
r02) and Cd (tx + r10, ty + r11, tz + r12) can be expressed as a value considering a three-dimensional matrix. On the other hand, CC

Coordinate LED.A (Ah, Av), LED of each point in D image.
B (Bh, Bv), LED.C (Ch, Cv), LED.D
Both (Dh, Dv) are known. Therefore, from these known data and the coordinates of each point viewed from the CCD camera 13, the variables tx, ty, tz, r00 to r12.
Can be calculated, and the element of the line-of-sight vector of the CCD camera 13 is determined. The reason that the value included in the second term of the coordinate Cc is twice the value of r00, r01, and r02, that is, proportional, is because the screen is flattened and expressed (pseudo). Actually, the screen 121 is a curved surface. Considering that there is, a three-dimensional matrix that considers the curvature of the curved surface may be defined for each coordinate. Then, from the elements of the obtained line-of-sight vector, for example, det = r00 × r11−r01 × r1
0, H = (r11 x (-tx) -r01 x (-ty)) x det, V = (-
The line-of-sight vector det and the intersection point (H, V) are obtained as r10 × tx−r00 × (−ty)) × det.

LED6A, LED6B, LED6
As described above, C is not limited to a constant pitch, but even in this case, it can be calculated if it has each pitch information. In addition, the game control unit 103 is based on the information obtained by the intersection (H, V) calculation unit 4018 or the information obtained by the line-of-sight vector calculation unit 4017 and the intersection (H, V) calculation unit 4018. , A trajectory calculation unit that calculates the trajectory of a bullet flying from the landing position on the screen 121 into the game space.

In FIG. 21, first, a predetermined period, for example, 1/6
The CCD camera 13 is operated by the trigger condition such as vertical synchronization (V-sync, V-blank) every 0 seconds to take an image (CCD).
Data is captured (ST811), and the captured data is binarized by the binarization processing unit 4012.
Bright spots are extracted (ST812). Here, the coordinates of the binarized data treated as the bright spots are taken in, the identification codes are attached to each of them (labeling), and appropriate grouping processing is performed in a mode in which the coordinate data are dispersed (ST813). Then, based on the position data of the bright spots, the group information, and the shape information (created as necessary), the rough identification of the bright spots is performed (ST814). Subsequently, the bright spot group forming the “L frame” is extracted from the bright spot positions, and A, B, C, and D are encoded based on the arrangement state of the extracted bright spots (for example, the LED 6 in the marker 6).
(Corresponding to A, 6B, 6C, 6D) is applied (ST81
5).

Next, the LEDs A to D are multiplied by the coefficient corresponding to the image pickup range of the screen 121 surface of the CCD camera 13 by any of the markers 6 to 9 (ST816). In the present embodiment, as described above, the distance from the CCD camera 13 is sequentially different (distance) from the upper part to the lower part of the screen 121, and by multiplying by the coefficient according to the ratio of the distance difference. , The correspondence (ratio) between the CCD image and the actual distance on the screen 121 is made constant. Then the LED.
From the coordinate data of A, B, and C, the coordinate tz of the z component of the CCD camera 13 with the "L frame" as the origin is calculated (S
T817), and then the x component tx, y component ty, r00, r01, r02 are calculated from the camera coordinate tz (ST818),
Then, based on the coordinate data tx, ty, tz of LED.D, r1
0, r11, r12 are calculated (ST819), and then tx,
From ty, tz, r00, r01, r02, r10, r11, r12, the intersection (H, V) with the line-of-sight vector of the camera when the "L frame" is regarded as a plane is calculated (ST82).
0). When the calculation is completed, the intersection (H,
V) and the like are transferred to the CPU 103 side, and are applied to the hit determination processing of the enemy character and the like (possibly including landing effect). Further, when a plurality of markers are lit, the intersection (H, V) may be calculated from the remaining “L frame” and appropriate intersection data may be adopted.

FIG. 22 is a detailed subroutine of ST815. First, the existing bright spot positions are constructed (created) with a vector and a distance (ST831). The bright spot position data in the graph is organized according to the grouping described above and in some sort of sorted state to facilitate data analysis. Then, using the vector, for example, an inner product of two adjacent points is calculated to check whether or not the three bright points have a linear relationship (ST832). If there is no linear relationship (No in ST833), it is determined whether or not the processing has been completed for all combinations (ST83).
4) If it is in the middle, return to ST832, and if all are finished, skip to ST821. On the other hand, if there is a linear relationship in ST833, knowledge (a situation where they are arranged) based on the distance between the bright points, that is, it is confirmed whether or not the three points are arranged at substantially equal intervals on the main axis (ST835). If there is no combination of substantially equal intervals, the process returns to ST832, and if there is a combination, it is in the vicinity (distance that LED.D constituting the L frame is considered to exist) to both ends of the three bright points. Check the bright spots (ST837). At this time, if there is no bright spot in the vicinity (N in ST838,
o), returning to ST832, if there is any, the relation between the bright points in the vicinity and the bright points forming the main axis is investigated, and the shape of "L"
It is estimated whether or not it is a "frame" (ST839). The reason why the bright spot is treated as LED.D depending on the presence / absence of the vicinity is that the orthogonality with LED.A and the equidistant relation may not hold depending on the orientation of the camera.
Then, A, B, C, and D are coded from the positional relationship of each bright point to confirm the arrangement (ST840).

By the above-described muzzle direction detection processing, C
The position of the muzzle 16 on the screen 121, that is, the position on the screen corresponding to the center of the CCD image is calculated based on the characteristic of the positional relationship of the marker images in the CD image. The position of the virtual trajectory of the bullet fired from the muzzle toward the target object in the game space can be calculated from.

FIG. 23 is a block diagram showing the configuration of the main part of the image processing section 410 which performs the image display processing in ST99 of FIG. 16, and FIG. 24 is a flowchart showing the detailed procedure of the image display processing in ST99. is there.

FIG. 25 is a diagram showing the display of a corrected image on this game machine, FIG. 26 is a diagram showing the display of a normal image, and FIG. 27 is set on this game machine. It is a figure for demonstrating an image correction parameter.

When a normal image as shown in FIG. 26A 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 difference between the upper part and the lower part of 4 is different, an image as shown in FIG.

On the other hand, in this game machine, the image projected from the projector 31 is corrected before projection as shown in FIG. 25 (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 process, 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, and the corrected image is projected from the projector 31.

As shown in FIG. 23, the image processing unit 410 for displaying an image while performing these corrections changes the 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
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).
_FT, a table associating the angle CAM_FB that specifies the lower end of the image) and reads and sets the image correction parameter corresponding to the line-of-sight elevation angle, and the drawing control unit 101
And an image generation instruction unit 4103 for instructing the generation of an image.

Actually, from the line-of-sight elevation angle EYE_R, the inclination angle CAM_ of the virtual camera is next calculated as shown in FIG.
R, image upper end angle CAM_FT and image lower end angle CA
M_FB can be designated, and these correspondences are held in the image correction table 422.

In the present game machine, the estimated gaze position VIEW_P is set according to the distance between the player and the dinosaur and the part of the dinosaur that causes an attack on the player when approaching. As shown in FIG. 27A, 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. 27B, 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. 27 (c), the projected image upper end SCREEN_U and the projected image lower end SCR
A straight line q ₃ passing through EEN_D and a virtual viewpoint position EYE_P
CAM_VP is the intersection of the line q ₃ and the perpendicular q ₄ to the line q ₃ , and the angle (elevation angle) between the line q ₄ and the horizontal line is
The inclination angle of the virtual camera is CAM_R. Further, the angle between the straight line q ₄ and the straight line q ₁ that determines the position of the upper end of the projected image is CAM_FT, and the position of the lower end of the projected image is (CAM
Let CAM_FB be the angle between the straight line q ₁ and the straight line q ₂ defined (with _FT).

With 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 processing using these image correction parameters, as shown in FIG. 24, 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, in the image generation instructing section 4104, the image correction parameter (CAM) is set with respect to 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 display portion on the screen, so that 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 player's line of sight 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.

Furthermore, 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 a 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 upper part of the 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 is provided so as to incline the virtual image to the outside of the screen when the real image is projected on the upper part 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.

Further, regarding the detection of the direction of the muzzle, the structure and effect of the shooting video game machine described above can be summarized as follows.

This shooting video game machine accepts the input corresponding to the shooting to the dinosaur displayed on the screen by the operation of 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 a trigger is pulled, an image of one of the plurality of markers arranged on the screen so as to have a predetermined positional relationship, The shooting position on the screen, which substantially corresponds to the center of the imaging range, is calculated from the position of the marker image and the rotation angle by identifying in the generated CCD image.

According to this game machine, it is possible to identify which part on the screen is being imaged and to calculate the shooting position from the position and angle relationship of the marker image in the CCD image. The orientation of the gun unit can be detected smoothly with respect to the screen that does not fit.

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

This shooting video game machine allows the player to play the game while displaying an image captured from a virtual viewpoint corresponding to the position of the player in 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 inclining 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, image correction parameters for instructing the rotation of the virtual camera according to the rotation of the mirror (and the line-of-sight elevation angle set during the progress of the game) are set in the image drawing processor so that these images can be displayed. By performing the correction, effective image correction can be realized by simple control.

With regard to the shooting video game machine of the above-described embodiment, the following modifications can be envisioned.

FIG. 28 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 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 size of the movement width of the player detection sensors 51 to 54 upon reaction 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. 29 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. 30 is a diagram showing image correction parameters set in the shooting video game machine of the third modification.

In the game machine of this modification, SCREEN_U 'is designated on the extension line of q ₁ shown in FIG. 27 (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. (1) 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 tilt 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. (2) In the shooting video game machine according to the above-described 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. (3) Regarding the avoidance movement by the player detection sensor, not only the movement to the left and right but also the bottom or
The movement can be made to lie down diagonally to the right and diagonally down to the 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. (4) By extending the screen of the shooting video game machine according to the above-mentioned embodiment to a position above the player in the play area and installing the screen so as to cover and cover the player, the player can display the upper image. 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. (5) 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 mirror,
The virtual image can be appropriately adjusted so as to be projected to the outside of the screen according to the positions of the projector and the screen. (6) In the shooting video game machine according to the above-described embodiment, when the image is displayed, the mirror rotation angle is associated with the line-of-sight elevation angle in advance, and the image correction parameter is stored in advance. The parameters can be sequentially calculated in the procedure shown in FIG. Furthermore, all or part of the screen onto which the image to be corrected is projected is assumed to be tilted up and down, and curved or tilted left and right or diagonally,
Further, it may have a hemispherical shape or the like. In addition, when projecting onto a curved screen (up, down, left, right, hemisphere, etc.), the entire screen is divided into several areas, and the same correction as above is performed according to the position of each area. Can be Furthermore, the front screen and at least 2 slantingly (from the player's perspective)
When three screens are arranged side by side so as to surround the player, and the three screens are continuously displayed, the same correction as described above is applied to the display on the two screens inclined in the oblique direction. Can be (7) In addition, in the shooting video game machine according to the above-described embodiment, the part of the dinosaur that causes an attack is partially displayed when approaching the virtual viewpoint, but the direction of the virtual viewpoint in the game space is changed. In addition, it is possible to display a portion that the player wants to pay attention in the progress of the game. (8) Furthermore, in the shooting video game machine of the above-described embodiment, the projection image is moved in the vertical direction on the screen with the mirror axis for rotating the mirror as one axis. The projection image may be provided on the screen and moved in the vertical and horizontal directions. (9) The above embodiment has shown an example applied to a shooting game machine, but the present invention is not limited to this, and the object to be designated is an instruction on a screen such as an image (including a character image). Thus, for example, it is possible to assist in bidirectional information transmission. Further, the present invention is not limited to the image display surface, but can be applied to a mode in which a desired position on the surface of the area to be specified is specified. In these cases, the controller is a simulated gun,
A form suitable for the purpose can be adopted. (10) The target area surface is not limited to the projection screen, but various display surfaces such as a television monitor, a liquid crystal monitor,
The same applies to a monitor screen of a personal computer. (11) As shown in the present embodiment, it is possible to perform 2P play, and it is also possible to simultaneously calculate orientations for a plurality of controllers, and thus it is possible to provide a highly versatile orientation detection device. (12) Since the structure is analyzed using a three-dimensional matrix,
It can be sufficiently applied to a mode in which the controller moves in a three-dimensional space. Therefore, the application range can be expanded. (13) In the present invention, the size and size of the marker does not matter. Various sizes can be adopted in consideration of the size of the screen to be applied and the surface of the target area. Further, the shape and form of the markers are not limited to the aggregate of dots and may be rods. In particular, the dimension data of each LED of the marker is not considered. That is, CCD camera 1
If the LED interval data for when 3 is at the reference position is stored in advance as reference data, the calculation process can be performed in the subsequent measurement according to the ratio with the reference data. A micro fluorescent tube or the like can be adopted as the rod-shaped body, and various materials can be adopted in the case of the reflector. Further, a mode in which a point body and a rod body are used together may be used. For the L frame, two rod-shaped bodies each having a predetermined size, preferably the same size, are arranged in a direction orthogonal to each other with their one ends aligned or close to each other, and on the extension of the other end of the one bar-shaped body. An L frame can be manufactured by arranging at least one point-like body at a predetermined distance. In the above, in the aspect in which the two rod-shaped bodies are arranged such that one ends thereof are close to each other, that is, separated by a predetermined distance, the point-shaped bodies are not always necessary. The recognition positions for the rod-shaped body are the end portion and the bent portion, which are extracted from the captured image captured by the CCD camera 213. Also, as the CCD camera 13, a color CCD
In the case where the two rod-shaped bodies are arranged such that one ends thereof are aligned with each other, the rod-shaped bodies of one shaft connected with ones emitting different colors in the middle are used. Four points, that is, two end portions, a bent portion, and a portion having different emission colors can be recognized, which is effective as an L frame. (14) The L frame shown in the present embodiment is not affected by the shapes and sizes of the game screen and the display screen, and has only one analysis method, and thus has high versatility. (15) In the present embodiment, four markers 6 to 9 are arranged on the screen 121, but one or more markers may be arranged depending on the size of the screen, the field of view of the CCD camera 13, and the like. Also, there is no need to arrange them at equal intervals. (16) As the markers that can be adopted in the present embodiment, it is possible to adopt two types of L-shapes having a mirror surface relationship (vertical axis or horizontal axis), and in this case, they can be individually identified, that is, arranged. Since it is possible to identify the position, it is not necessary to perform individual lighting control as in the present embodiment. Also, the rotation range is 1
In the aspect of the controller of 80 degrees or less, four types of L frames having a mirror surface relationship with respect to the vertical axis and a mirror surface relationship with respect to the horizontal axis can be adopted. Even when adopting, the individual lighting control is completely unnecessary. That is, a different type (2 types or 4 types) of directional position detection markers having a form (corresponding to the above-described mirror surface relationship) in which the other axis includes axis information in which the other axis is opposite to the one axis in the two axis directions. It is possible to adopt an aspect in which the target area surface (screen or the like) is arranged so as to have a predetermined positional relationship. According to this, by adopting different types of directional position detecting markers having the same basic form (that the main axis and the sub axis are orthogonal to each other), it is possible to use the same type of marker for individual determination. No processing is required.

Further, as another arrangement mode of the markers, the arrangement of the present embodiment (four positions in the vertical direction at the left-right center of the screen) will be described as an example. For each of the four vertical positions, for example, with respect to the vertical axis. There is a mirror surface relationship (or the above 4
Two types (of types) of L frame markers may be arranged at symmetrical positions on the screen. Also,
The two types of L frame markers may be alternately arranged at four positions in the vertical direction. In this case, since the markers for two stages vertically adjacent to each other are markers of different types,
Lighting control can be performed in units of three groups, that is, a group of the second and third rows, a group of the second and third rows, and a group of the third and fourth rows. This can also be applied to the case where three types of L frames, and further four types of L frames are arranged adjacent to each other in units of the number of types. (17) In the present embodiment, the LED as the light emitting body is adopted as the light source, but instead of this, a reflector capable of reflecting incident light from the front may be adopted. In this configuration, light is emitted from the front of the target area surface (at a predetermined position or provided in the controller) by a light emitting body or the like, and the reflected (emitted) light from the reflector is received by the imaging means. Is. With this, it is not necessary to directly equip the surface of the target area with the light-emitting body, so that the configuration is easy and versatility is high. Preferably, the shape of the reflector is preferably, for example, a hemispherical sphere or the like in that it generates reflected light with a required width, and the range of movement of the image pickup means, that is, the controller is not unnecessarily restricted and the versatility becomes high. A structure may be employed in which diffused reflection is generated by surface treatment on the reflection surface to expand the reflection range. (18) The light source (light emitter, reflector) is not limited to infrared light, and may use light of a desired color. For example R
It may be (red), G (green), B (blue), or light of another color. When three markers are adopted, if the color CCDs use markers of different colors and enable the CCD camera to receive light of each color,
Since the arrangement of each marker can be recognized, there is an advantage that the individual lighting control as shown in the present embodiment is not necessary and the lighting state can be kept constant. Of course, it is not necessary to use three colors at the same time, and a marker of a desired color may be adopted according to the application. (19) The marker is not limited to the fixed type. For example, in the present embodiment, one slit extending in the vertical direction of the screen 121 is provided, the slit is arranged so that the marker faces, and a guide rail or the like for sliding the marker along the slit is provided to drive a motor or the like. If the marker is configured to be movable while controlling the position in the vertical direction and the motor is driven so as to track the position of the projected image, one marker realizes four markers in the present embodiment. It can also be treated as if it were present in many more positions. Therefore, the number used can be reduced. (20) In the present embodiment, the projection image is drawn on the front surface of the screen 121. However, depending on the shape of the screen, it is also possible to draw a game image in which images are projected from both projectors on both the front and back surfaces. . In this case, for example, a marker provided with each LED is integrally formed, or each LED is preferably formed in a hole penetrating the thickness of the screen so that the front and back surfaces of the screen can also be used for image pickup by a CCD camera. May be mounted flush with each other, and configured so that light from the light emitting portion of the LED can be emitted to both the front and back surfaces of the screen (the same applies to a reflector, for example, the reflective surface is a sphere). It should be attached within the wall thickness so that the members are exposed half on each side).
By doing this, it becomes possible to play games using both front and back sides of the screen, for example, the image from the front of the dinosaur is displayed on the front side, and the image from the back side of the dinosaur is displayed if it goes around the back side of the screen. As a result, a highly entertaining and highly entertaining game can be provided. Moreover, the marker has three types of shapes on the front surface and the back surface of the screen, which are mirror-like with respect to the vertical axis as they are, so that only the image from the CCD camera is recognized and either side of the screen is automatically detected. It is possible to detect, and it is not necessary to additionally provide a human body sensor for detecting the turning movement of the player himself. (21) Although various shapes of the marker are possible, those that basically include the elements of the L frame are included in the concept of the L frame.
