Description

  The present invention relates to a shooting game apparatus, and more particularly, to a video shooting game apparatus capable of performing a hit determination even when a display device that displays a game image including a target is other than a CRT.

Shooting game devices are enjoyed by many people in game centers and other playgrounds.
In a video shooting game device, there are roughly two types of methods for determining whether or not a target on a display screen has been hit.
One is that the simulated gun is attached to the pedestal, and a sensor that can accurately detect the orientation of the simulated gun is attached to the simulated gun or pedestal, and the orientation of the simulated gun when aiming at the target is displayed on the display screen This is a method of performing hit determination based on whether or not the target position matches.
Another method is to shoot a target portion (aiming position) on the screen of a CRT display device with a camera attached to a simulated gun, and that target screen based on the time when the light spot of the scanning line passes through that portion. This is a method in which the position of a part is specified, and hit determination is performed based on whether or not the position matches a target position displayed on the screen (for example, see Patent Document 1 below).

In the former method, it is necessary to attach a simulated gun to the pedestal, so the position of the simulated gun (that is, the position where the shooting operation is performed) is fixed, and it is difficult to expand the game content by changing the firing position of the gun There is a problem that.
On the other hand, the latter method allows the player to shoot from various positions with a simulated gun in his hand, and the game content can be expanded by changing the gun firing position, but the CRT display Since the hit determination is performed using the scanning line of the device, there is a problem that it cannot be applied to a display device in which the scanning line is not displayed.
That is, since the scanning line is not displayed on a liquid crystal display device (LCD: Liquid Crystal Display) which is currently used as a large display means or a display screen by a projector, the latter method cannot be used. is there.

  The present invention has been made to solve the above-described problems, and the object of the present invention is to apply a hit determination method similar to that using a scanning line in a liquid crystal display device or a display screen by a projector.

FIG. 1 shows an outline of a shooting game apparatus according to the present invention, and FIG. 2 shows an operation principle of a hit determination method of the shooting game apparatus according to the present invention.
As shown in these drawings, the shooting game device according to the present invention is roughly divided into a display device (10) on which a game image including a target is displayed, and a simulated gun (11) having a CCD camera (111). The invisible light beam deflection scanning device (12) that scans the screen of the display device with an invisible light beam, controls the operation of the entire game device, analyzes the output image from the CCD camera (111), and hits the target And a game calculation device 13 for determining whether or not the game has been performed.
The display device 10 according to the present invention is a liquid crystal display (LCD), a projector, or the like, and scanning lines do not appear on the display screen 100. Therefore, as shown in FIG. A pseudo scanning line 1200 is drawn by scanning over 100 with an invisible light beam 120 from an invisible light beam deflection scanning device 12 (hereinafter also simply referred to as a “scanning device”).
As the invisible light beam 120, a light beam that is not visible to the player, such as an infrared laser beam, is used so as not to obstruct the visual observation of the game image displayed on the display screen.

The player uses the simulated gun 11 to trigger the target image 100a displayed on the display screen 100.
A CCD camera 111 is attached to the simulated gun 11, and an image of a position where the simulated gun is aimed (not necessarily a target image because it is not necessarily hit) is, for example, 0. Shooting continues for 1 second (shooting time T).
When the scanning point by the invisible light beam passes through the photographing position (aiming position) during the photographing period, the output image of the CCD camera 111 is detected by the invisible light detection circuit 112 such as infrared detection, so that the scanning point detection signal is obtained. Therefore, the fact that the detection signal is obtained is transmitted to the aiming position calculation circuit 131.
When the invisible light beam scans the display screen 100, the counter 131a provided in the aim position calculation circuit 131 counts the elapsed time from the scanning start position (the upper left corner of the screen 100), and the scanning point is the screen. It is reset when it reaches the lower right corner and returns to the upper left corner again, and the count is restarted from 0 simultaneously with the start of the next scan.
Therefore, based on the count value of the counter 131a when the invisible light detection circuit 112 detects invisible light from the output image of the CCD camera 111, it is determined where the aiming position photographed by the CCD camera 111 is on the display screen. be able to.
Thus, the aim position calculation circuit 131 can calculate the aim position of the simulated gun 11 when the player pulls the trigger from the count value of the counter 131a when the detection signal from the invisible light detection circuit 112 arrives. it can.

The value of the aiming position of the simulated gun 11 calculated by the aiming position calculating circuit 131 in this way is provided to the hit determination circuit 132 (see FIG. 6), and the target image is displayed on the display screen. It is checked whether or not it matches the position of 100a, and it is determined that if it matches, it is hit, and if it does not match, it is determined that it is off.
The position of the target image 100a on the display screen is known in the game calculation device 13 that executes the game program and controls the display of the game image. It is possible to determine whether or not there is a hit by comparing with the value of the aiming position of the simulated gun 11 calculated by the aiming position calculating circuit 131.

In order to ensure that the scanning point by the invisible light beam 120 passes through the imaging position (aiming position) during the period (T) when the CCD camera 111 is triggered and the aiming position is captured. T is set so that the invisible light beam 120 is longer than the one-time scanning time t of the entire screen until the invisible light beam 120 scans from the upper left corner of the display screen 100 in the X-axis direction and reaches the lower right corner.
For example, when the entire display screen is scanned 10 times per second, the photographing time by the CCD camera 111 is set to 0.1 seconds or more.
The number of scanning lines in the screen and the number of scans for the entire screen per second are determined by the accuracy of the hit determination, and thus depend on the size of the target image, the resolution of the CCD camera, etc., for example, the number of scanning lines is 50 to 500 lines and the number of scans per second are determined within a range of about 5 to 50 times.
The reset operation of the counter 131a performed each time the invisible light beam 120 returns to the upper left corner of the display screen 100 is performed based on the scan control signal from the control circuit 122 of the scanning device 12.
Further, as indicated by a broken line in the display screen 100 in FIG. 2, the invisible light beam 120 is changed during a period in which the scanning point by the invisible light beam 120 moves from the left side of the screen to the right side and then returns to the left side one step below. It is desirable to turn on and off the light source device 121 by a control signal from the scanning device control circuit 122 so as to turn it off.

Next, the configuration of the invisible light beam deflection scanning device 12 that deflects the invisible light beam emitted from the light source device 121 and scans the display device screen 100 will be described.
The invisible light beam deflection scanning apparatus shown in FIG. 3 is a two-axis rotating mirror type raster scanner, and an invisible light beam 120 such as an infrared laser emitted from a light source device 121 is applied to an X-axis motor 12a including a servo motor. The invisible light beam 120 is deflected so as to turn around the rotation axis of the reflecting mirror 12b by being reflected by the two-surface reflecting mirror 12b attached to the rotating shaft, and the turning invisible light beam 120 is further converted into the Y-axis motor. By reflecting with the two-surface reflecting mirror 12d attached to the rotating shaft of 12c and deflecting to turn around the rotating shaft of the reflecting mirror 12d, scanning in the XY axis direction is performed on the display screen 100. It is what I did.
When the display screen 100 is scanned once from the top to the bottom in the Y-axis direction, for example, when the display screen 100 is scanned 300 times in the X-axis direction (that is, when 300 scan lines are formed), the Y-axis The X-axis motor 12a may be rotated 300 times while the motor 12c is rotated once.

FIG. 4 shows another example of a two-axis rotating mirror type raster scanner. The invisible light beam 120 emitted from the light source device is attached to the eight side surfaces attached to the rotating shaft of the X-axis motor 12e. The invisible light beam 120 is deflected so as to turn about the rotation axis of the reflecting mirror 12f by being reflected by the eight-surface reflecting mirror 12f provided with the reflecting mirror, and is scanned in the X-axis direction on the display device screen. It is a thing. Since one scanning line is formed in the X-axis direction by one reflecting mirror, eight scanning lines are formed when the reflecting mirror 12f is rotated once.
Therefore, if the invisible light beam reflected by the reflecting mirror 12f is further reflected by another reflecting mirror (not shown) rotated by the Y-axis motor and irradiated to the display screen, the entire display screen is obtained. Scanning becomes possible.

FIG. 5 shows still another embodiment of the invisible light beam deflection scanning apparatus.
This invisible light beam deflection scanning apparatus is a scanner using an electro-optic crystal 12g such as a KTN crystal (potassium niobate tantalate crystal) that has recently been provided to the market. Since the electro-optic crystal has a characteristic that the refractive index of light changes when an electric field is applied thereto, the X-axis direction and the Y-axis direction of the electro-optic crystal 12g while passing the invisible light beam 120 through the electro-optic crystal 12g. By changing the operation voltage, it is possible to change the emission direction of the transmitted invisible light beam 120 and to perform scanning in the XY axis directions on the display screen 100.

Next, the circuit configuration of the shooting game apparatus according to the present invention will be described with reference to FIG.
In FIG. 6, the same reference numerals as those in the drawings so far indicate the same components.
A predetermined game program is installed in the game calculation device 13 shown in FIG. 6, and the game calculation is performed according to the above-described game program in response to various signals and data output from the simulated gun 11 operated by the player. The game image data to be displayed on the display device 10 is output as the game progresses.
The image processing circuit 14 converts the game image data output from the game calculation device 13 into a display device image signal, and supplies it to the display device 10.

The CPU 13a in the game calculation device 13 executes a game program recorded in a storage device 13b such as a hard disk drive, and performs calculation processing necessary to advance the game according to the program.
The work RAM 13c exchanges data necessary for the operation of the CPU 13a, and temporarily records and holds data.
In addition to basic character data, image data, audio data, etc. used in the game, various data and programs of a relatively small size necessary for backing up the operation of the CPU 13a are recorded in the ROM 13d. If the storage device 13b is a large-capacity storage device such as a hard disk drive, character data, image data, etc. may be recorded there.
The clock circuit 13e oscillates clock pulses necessary for the operation of the entire apparatus, and performs time management from the start of the game to game over, other time management necessary for the progress of the game, and the like. In the present invention, the oscillation pulse of the clock circuit 13e is also used as an operation pulse that is the basis of the count value of the counter 131a that is required when calculating the aiming position of the simulated gun 11.

Furthermore, the aim position calculation circuit 131 and the hit determination circuit 132 are constructed as circuit elements for determining the result of shooting with the simulated gun in the present invention by these hardware and the game program installed therein. The
These circuit elements are executed by hardware such as the CPU 13a, the storage device 13b, the work RAM 13c, and the ROM 13d by a game program (software) installed in hardware such as the CPU 13a and the storage device 13b of the game arithmetic device 13. It is constructed by the cooperation of the software and hardware.

The aiming position calculation circuit 131 analyzes the output image of the CCD camera 111 of the simulated gun 11 as described above, and the irradiation position of the simulated gun based on the time when the invisible light beam passes the aiming position, that is, the count value of the counter 131a. Is calculated.
The hit determination circuit 132 determines whether or not there is a hit by determining whether or not the aim position obtained by the aim position calculating circuit 131 matches the target position displayed on the display device screen.
The game calculation device 13 performs a predetermined game calculation according to the determination result of the hit determination circuit 132 and according to the game program, and displays the result on the display device screen 100 as a game image.

  The present invention is not limited to the above-described embodiments. For example, as the invisible light beam deflection scanning device 12, various known means other than the biaxial rotating mirror type raster scanner and the electro-optic crystal scanner are used. Therefore, the present invention includes within its scope all modifications that can be easily conceived by those skilled in the art from the above description.

  The present invention is configured as described above, and a pseudo scanning line is generated on the display device screen by an invisible light beam such as an infrared laser, and the hit determination is performed using the scanning line. It is also possible to make a hit determination even on a display screen where a scanning line does not appear, such as a projector, which makes it possible to shoot from various positions while moving a simulated gun, and change the shooting position of the gun to the game content Since it is possible to provide a shooting game device that can be expanded, it has great utility value in the industry.
