When the display unit 11 is a projector and is a translucent projection screen, the display unit 11 may be arranged so as to look down at the screen from the inside of the main body housing unit 10, that is, from the back surface of the projection screen.
[0023]
2A and 2B are diagrams showing the structure of a simulated gun, where FIG. 2A is an overall perspective view, FIG. 2B is a side view, FIG. 2C is a view looking through the scope, and FIG. FIG. In FIG. 2, four simulation guns 30 having the same shape and function are prepared, and each simulation gun 30 is connected to the operation housing unit 20 via a cable 301. The cable 301 includes a power line and a signal line inside, and also functions as an antitheft device for the simulated gun 30. The simulated gun 30 mimics the general structure of a rifle including a barrel part, a barrel part, a shoulder pad part, and a trigger part. A laser emitter 32 (see FIG. 3) that emits laser light in the infrared wavelength band toward the front of the muzzle is provided inside the gun barrel as a light projecting unit. A sighting device 33 is provided on the upper surface of the barrel. The laser emitter 32 and the infrared camera 40 constitute position specifying means.
[0024]
A trigger 34 simulating a trigger is disposed under the barrel portion, and a trigger switch 341 (see FIG. 3) that is turned on in response to a pulling operation of the trigger 34 is incorporated. A trigger operation is detected by the trigger switch 341, and processing as a virtual shooting operation is executed. Further, an eyepiece sensor 35 is provided at a position where an eye for looking through the sighting device 33 is placed, and a shoulder sensor 36 for detecting that the shoulder is in contact with the shoulder rest portion.

Further, as shown in FIG. 2D, in the posture in which the gun is normally held, the shoulder sensor 36 hits the shoulder of the player PL and the eye sensor 35 remains off, so that the player PL normally holds the gun. It is detected that it is ready.
[0025]
When the eyepiece sensor 35 and the shoulder sensor 36 are turned on at the same time, a scope display request is processed as described later. In this embodiment, an image of a scope mark is displayed in a game image displayed on the display unit 11 as described later. . The laser emitter 32 may be turned on during the game, or in a mode in which a sensor structure that can detect the half-drawing state and the full-drawing state of the trigger 34 is identifiable, the trigger is operated (at least half-pull). It is good also as an aspect which turns on only while it was set to the state.
[0026]
The infrared camera 40 uses the screen of the display unit 11 as a visual field frame and detects light in the infrared wavelength band. Spot light emitted from the simulated gun 30 and arriving on the screen of the display unit 11 (player PL is not visible). ) Can be captured (detected), and the captured image is guided to the control unit 100 (see FIG. 3) to obtain the coordinates of the imaging position of the spot light on the screen. That is, the vertical and horizontal positions of the screen of the display unit 11 and the vertical and horizontal arrangement (coordinates) positions of the CCD elements that are the imaging elements constituting the infrared camera 40 are associated as coordinates, and the coordinates of the CCD elements that image the spot light. From this, the position of the display unit 11 is obtained.
[0027]
FIG. 3 is a block diagram of the shooting game apparatus. The shooting game apparatus includes a control unit 100 having a microprocessor and the like, and also includes game data including a vertex coordinate data of polygons for displaying each character on the display unit 11, game programs, sound effects such as sound effects, and the like. It includes a ROM 120 for storing data, texture data for pasting to a polygon, and other various data necessary for game processing, and a RAM 130 for temporarily storing data being processed. The recording medium for storing the game program or the like is not limited to the ROM 120, and various memories can be adopted. The game program or the like is installed on the recording medium from the outside, or the installed recording medium is the present apparatus. It is good also as an aspect provided with required data by loading. The game image is a pseudo three-dimensional image in the present embodiment, and a landscape image, an enemy character, and other various objects (for example, for displaying proximity bursts that produce landing when shooting is missed) include a required number of polygons and Created using textures.
[0028]
A trigger switch 341, an eye sensor 35, a shoulder sensor 36, and a laser emitter 32 of four simulation guns 30 are connected to the control unit 100 via a cable 31. The control unit 100 can identify which simulation gun 30 the detection signals from the trigger switch 341, the eye sensor 35, and the shoulder sensor 36 are from, and instructs the predetermined simulation gun 30 to emit laser light. Can be output. The coin sensor 241 detects that a predetermined number of coins have been inserted into the insertion slot 24.
[0029]
The display RAM 11a has a memory capacity for storing game images to be displayed on the display unit 11. The game image to be displayed on the display unit 11 is repeatedly updated every predetermined period, for example, 1/60 seconds, and displayed each time. The data is read by the unit 11.
[0030]
The control unit 100 includes a built-in timer 101 and also includes the following function execution unit.
[0031]
The game progress processing unit 102 receives each operation and detection signal from each simulated gun 30 and controls the progress of the game according to the game program stored in the ROM 120. In the present embodiment, when another player PL is allowed to participate in the game in the middle of the game, the coin sensor 241 detects the insertion of a coin, and a signal indicating that a predetermined start button 23 is pressed is input. The simulated gun 30 corresponding to the start button 23 can be operated, and can participate in the game.
[0032]
As shown in FIG. 5A, the background texture generation unit 103 uses a polygon based on polygon vertex coordinate data and the like stored in the ROM 120, and has a predetermined resolution (the same as the scope image in this embodiment). With the resolution, an image of the entire background (including enemy characters) is generated in the enlargement RAM 140 (hereinafter, this generated image is referred to as a background texture). In the present embodiment, the background texture has a resolution higher than that of a display image described later. The enlargement RAM 140 has a memory capacity for image data having the predetermined resolution. Although the enlargement RAM 140 and the display RAM 11a are actually the same RAM, for the convenience of explanation, the enlargement RAM 140 and the display RAM 11a are individually shown in FIG.
[0033]
As shown in FIG. 5C, the display image display processing unit 104 reduces (compresses) the background texture in the background drawing area shown in FIG. 5B provided in the storage area of the display RAM 11a (hereinafter, referred to as “image”). Display image). This display image is an image displayed on the display unit 11 and is an image having a lower resolution than the background texture. The number of polygon vertices processed in this reduction processing is 4 (pieces).
[0034]
The scope display determination unit 105 instructs to display a scope image corresponding to the simulated gun 30 while the eye sensor 35 and the shoulder sensor 36 of the simulated gun 30 are simultaneously turned on.
[0035]
The scope image display processing unit 106 performs display processing of the scope image corresponding to each simulated gun 30. 4A and 4B are screen views showing an example of a scope image display. FIG. 4A is a screen view when the scope image is not displayed, and FIG. 4B is a screen view when the scope image is displayed. In (a), if one enemy character AM1 is drawn in one place of the display image 1031 and the spot light from the simulated gun 30 is applied to this position, the scope image display processing unit 106 (b) ), A circular frame scope mark 1051 is displayed at the position, and a scope image 1052 that is an image enlarged at the scope magnification is displayed inside the scope mark 1051.
[0036]
Specifically, the scope image display processing unit 106 sets, for example, a scope mark 1051 shown in FIG. 4B around the center of the display image with reference to the coordinates of the spot light when the trigger-on signal is generated. Then, an image of a predetermined area centered on the spot light drawn in the scope mark 1051, that is, an image with a scope magnification set in advance as a scope function is extracted from the background texture in the enlargement RAM 140, and is stored in the display RAM 11a. Extraction / paste processing for overwriting and pasting the scope mark 1051 in the display image is performed. Therefore, in this embodiment, the scope magnification is determined by the ratio of the resolution of the background texture to the resolution of the display image. The number of polygon vertices processed in this extraction / paste processing is N (number) per scope (simulated gun) when the scope image is generated as an N-angle (number of vertices: N).
[0037]
Returning to FIG. 3, the shooting determination unit 107 determines whether or not the trigger 34 of the simulated gun 30 is pulled and the trigger switch 341 is turned on.
[0038]
The hit determination unit 108 manages the display coordinates of each object image including the enemy character AM displayed on the display unit 11, reads the coordinates of the irradiation position of the spot light from the simulated gun 30 at the time of output of the trigger on signal, When the coordinates coincide with the display coordinates of the enemy character AM, it is determined that it is a hit.
[0039]
The background texture generation unit 103 calculates a trajectory in which the bullets fired from the player side fly in the game space according to the determination results of the shooting determination unit 107 and the hit determination unit 108, displays the flight state, and In the case of (1), a win effect display (for example, the enemy character AM is deleted from the image) is performed, and in the case of a miss, an effect display indicating a proximity burst with respect to the landing position is also performed.
[0040]
The score management unit 109 receives a trigger-on signal from each simulated gun 30 and takes into account the number of hits (or hit rate) for enemy characters appearing in the game image or the game time managed by the built-in timer 101. Thus, the sniper ability of the player who operates each simulated gun 30 is numerically evaluated.
[0041]
The life management unit 110 manages the life of each player, for example, by increasing by hit attacks on enemy characters and decreasing by receiving attacks from enemy characters. The presence or absence of hits when attacking by an enemy character is, for example, the relationship between the flight direction of the attack from the enemy character on the left and right and the arrangement position of the gun stand 22, whether the simulated gun 30 is attacking (the trigger 34 is pulled). Various information such as whether or not the scope is being displayed can be adopted as the judgment material. Further, in this game, when the life falls to a predetermined value, for example, 0, during the game, the game progress processing unit 102 is forced to end the game.
[0042]
The sound processing unit 111 outputs necessary sound effects from the speakers 12, 13, and 25 in addition to sound effects such as shooting, landing, being hit, and proximity burst. The speaker 25 may be in charge of the player's shooting sound, the speaker 12 may be in charge of the attacking sound from the enemy character, and the speaker 13 may be in charge of the sound effect upon landing, being hit, or in the vicinity of the explosion.
[0043]
FIG. 7 is a basic flowchart of the game progress procedure.
[0044]
When the game apparatus is powered on, a predetermined demo screen is displayed (step ST1) and the game is waited (step ST3). When a coin is inserted and at least one of the four game buttons 23 is operated, a signal is detected from the I / O input of the control unit 100 (step ST5), and the process proceeds to game processing (step ST5). Step ST7). Here, when the life value becomes 0 or the like, the game is over in the middle. Otherwise, it is determined whether or not the preset stage is cleared, and the next stage is sequentially shifted to reach the final stage. Is determined (step ST9). When the final stage is cleared, an ending demo screen, for example, a game result such as a score is displayed (step ST11), the game over screen is displayed (step ST13), and this game is finished.
[0045]
FIG. 8 shows a “game process” subroutine in one stage in step ST7.
[0046]
In FIG. 8, first, it is determined whether or not all the players have lost their lives (step ST21). If so, the process returns as a game over. If the life of at least one player remains, the game image display process is continued (step ST23), that is, the game progress is executed and it is determined whether the stage is cleared (step ST25). If the stage is not cleared, the process returns to step ST21 and the game is continued. If the stage is cleared, the process returns as stage clear.
[0047]
FIG. 9 is a subroutine of the “game image display” process in step ST23.
[0048]
In FIG. 9, first, a background texture is generated in the enlargement RAM 140 (step ST31), and then a display image 1031 having a lower resolution than the background texture is generated in the display RAM 11a based on the background texture (step ST33). Then, a determination is made as to whether or not there is a scope display request from the captured data (step ST35). If there is no request for scope display, the process proceeds to step ST39. On the other hand, display processing of the scope mark 1051 and the scope image 1052 for displaying the scope is performed and overwritten on the display RAM 11a (step ST37). Next, it is determined whether or not all scope image display processes have been completed (step ST39). If there is any remaining, the process returns to step ST35 and the same processes are executed in order, and all scope display processes are terminated. Exit this flow.
[0049]
FIG. 10 shows the “scope image display processing” subroutine of step ST45.
[0050]
When there is a request for scope display, as shown in FIG. 10, the scope mark 1051 shown in FIG. 4B is set in the display image with the coordinates of the spot light at the time of occurrence of the trigger-on signal as the center, An image of a predetermined area centered on the spot light is extracted from the background texture, and the extracted image is pasted into the scope mark 1051 set as the display image (step ST41).
[0051]
Then, it is determined whether or not the extraction / pasting process has been completed for all scope images (step ST43). If not completed (NO in step ST43), the processes of steps ST41 and ST43 are repeated while the process is completed. If yes (YES in step ST43), the process returns.
[0052]
According to this scope image display processing, for example, the number of vertices required for background drawing is 4000, the number of vertices required for drawing a scope image is 2,000, the scope image is displayed as a 20-sided polygon (20 vertices), and the number of scopes displayed Is 4, the number of vertices required for the background texture generation processing is 4000, which is the same as the number of vertices required for background drawing, and the number of vertices to be processed is
(Number of vertices to be processed) = (number of vertices processed by background texture generation processing) + (number of vertices processed by background texture reduction processing) + (number of vertices required for scope image pasting processing) × (scope (Number of vertices to be processed) = 4000 + 4 + 20 × 4 = 4084 (number).
[0053]
On the other hand, in the conventional method of drawing a high-definition scope image separately from the game image displayed on the display unit 11,
From (number of vertices to be processed) = (number of vertices required for background drawing) + (number of vertices of scope image) × (number of scopes), (number of vertices to be processed) = 4000 + 2000 × 4 = 12000 (pieces)
It becomes. Therefore, the scope image display processing according to the present embodiment can reduce the number of vertices to be processed by 7916 (pieces), about 66%, as compared with the conventional case.
[0054]
As described above, when the scope image is displayed on the display unit 11, a background texture having the same resolution as the scope image is generated, and a display image having a lower resolution than the background texture is generated based on the background texture. After that, an image of a predetermined area centered on the spot light is extracted from the background texture, and this extracted image is pasted on the display image. Therefore, the number of vertices can be calculated and extended without reducing the resolution of the scope image. Thus, it is possible to reduce the load of the vertex calculation processing applied to the control unit 100.
[0055]
Further, since the image of the position designated by the simulated gun 30 is enlarged, a scope display function for showing the sniper position in more detail can be realized, and a sense of power and a sense of reality can be improved.
[0056]
In addition, a scope mark 1051 having a circular frame is displayed at a position of the display image 1031 where the spot light from the simulated gun 30 is applied, and a scope image 1052 that is an image enlarged at the scope magnification is displayed in a circle. Since this is done, it is possible to perform a simulated effect display of the scope display.
[0057]
In addition, the following modification modes (1) to (12) can be employed in the present invention.
(1) The scope display is based on the condition that the eye sensor 35 and the shoulder sensor 36 are simultaneously turned on. However, the scope display is not limited to this. For example, the scope display may be performed when the eye sensor 35 is turned on. May be configured to display a scope.
(2) When this shooting game is applied to a home game machine, for example, when a controller having a joystick or the like is configured to perform the function of the simulated gun 30, the scope portion can be moved by the joystick or the like. Good.
(3) Although the present invention has been described with a shooting game, the present invention is not limited to this, and if an appropriate place on the screen on which a display image is displayed is specified by a position specifying means such as a controller, a partial region including the part This is also applicable to a game that progresses when the above image is enlarged and displayed, thereby making it possible to observe the displayed image more finely.
(4) In this embodiment, as a result of using infrared light for position designation, the shooting position cannot be directly visually recognized on the screen, but a shooting marker is displayed at the detected spot light position using image processing. You may do it. Or in the aspect which installs this game device in a building, it is good also as an aspect which designates a position using the light which can be visually recognized.
(5) The number of simulated guns is not limited to four and may be any number. According to the arithmetic expression “number of vertices to be processed”, the effect of the scope image display processing according to the present invention increases as the number of simulated guns increases.
(6) As another embodiment of the position specifying means, a marker having a length information with respect to each of the two axial directions is prepared on one side of the simulated gun 30 or the main body housing 10 side, and this is provided on the other side. Or a method of calculating by calculation which position on the screen of the display unit 11 the position designation means is directed from the mapping situation on the captured image side. A simulated gun is directly imaged by a CCD camera, and a method for calculating the position and orientation of the simulated gun 30 and the target position on the screen of the display unit 11 based on the information from the captured image. Furthermore, as a simpler form, A predetermined position specifying mark (may be dot-shaped) or a position specifying mark similar to that described above is arranged or emitted on the outside of the screen, and this is displayed on the position designation means, for example, the muzzle direction on the simulated gun 30 side (designation) How to detect the direction of a possible adoption. As described above, the position designation means includes an aspect constituted by a set of a member indicating the position and a member to be detected, and an aspect in which detection is performed only on one side like a CCD camera or an ultrasonic transceiver.
(7) In the above embodiment, when the scope image is displayed, the image extracted from the background texture is overwritten and pasted in the scope mark 1051 in the display image. After the image in the mark 1051 is cut out, the extracted image may be processed so as to fit in the scope mark 1051.
(8) When it is necessary to change the magnification (size) of the extracted image, such as when the scope magnification is different for each simulated gun 30, the following processing may be performed. That is, the ratio of the resolution of the display image to the resolution of the extracted image (background texture) is set in advance to, for example, 0.25, and the scope image is obtained with a scope magnification of 5 times (with respect to the display image) for a certain simulated gun 30. In the case of displaying on the display unit 11, there is provided changing means for changing the magnification (size) of the extracted image, and the changing means has changed the magnification of the extracted image to 1.25 (0.25 × 5) times. The image may be combined with the scope mark 1051. Generally speaking, the ratio of the resolution of the display image to the resolution of the extracted image (background texture) is preset to m, and the scope image with a scope magnification of n times (with respect to the display image) for a certain simulated gun 30 Is displayed on the display unit 11, an image obtained by changing the magnification of the extracted image to mn times by the changing unit may be combined in the scope mark 1051.
[0058]
In this case, the resolution changes when the extracted image is enlarged by the changing means. However, since it is enlarged based on the extracted image (background texture) having a resolution of a certain level or more, the scope image is based on the display image. As compared with the case of generating the image, it is possible to suppress the deterioration of the image quality of the scope image. For example, in the case of the specific example described above, when a scope image is generated by enlarging an image of a predetermined region of the display image five times, the scope image becomes coarse (resolution becomes low). Extracting an extracted image from a background texture having a resolution of 4 times and expanding the extracted image at a magnification of 1.25 times smaller than the above 5 times to generate a scope image, thereby suppressing degradation of the image quality of the scope image can do.
(9) In the case where scopes with different display magnifications can be exchanged in a pseudo manner with respect to the same simulated gun 30, it is possible to change the display magnification of the scope image for the same simulated gun 30 by the changing means. Good.
(10) A telephoto function (zoom function) may be added to the scope of the simulated gun 30. For example, the scope magnification may be changed according to the player's will, or the scope magnification may be automatically increased as the player has higher sniper ability. In particular, in the latter case, a player with higher sniper ability is more likely to capture a sniper target, and by adding the privilege of improving the visibility of the sniper target, the player's desire to improve sniper ability is promoted. The taste of the game can be improved.
(11) In the above embodiment, when spot light from the simulated gun 30 is applied, the scope mark 1051 having a circular frame is displayed at the position, and the scope image 1052 is displayed inside the scope mark 1051. The position specifying means for specifying the position on the monitor screen is not limited to the one operated by the player (in the above embodiment, the simulated gun 30), but the control unit 100 is provided with a position specifying unit for specifying the position on the monitor screen. For example, the position designation unit may automatically designate the position on the monitor screen while displaying the demonstration screen, and the scope mark 1051 and the scope image 1052 may be displayed on the designated position.
(12) The present invention is not necessarily limited to the one that enlarges and displays an image at a specific position as in the above-described embodiment. For example, the present invention can be applied to a case where an image at a specific position is reduced and displayed. Even in this case, as described above, it is possible to reduce the number of vertex computations and, in turn, the load of vertex computation processing on the control unit 100.

Among images with resolution ofSniper specified by a simulated gunSince an image of a predetermined region based on the position is extracted as an extracted image, and this extracted image is synthesized with the designated position of the image of the second resolution, the resolution of the scope image is not reduced. Further, the number of computations of the vertexes of the polygon, and thus the load of the vertex computation processing can be reduced.
