Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shooting type game machine, and more particularly to a shooting type game machine capable of correcting an aiming position.

[0002]

2. Description of the Related Art Shooting games have been widely played in the past, and in recent years, such a game device has been used as a CR.
The display of targets on T is widespread.

In this shooting game device, a light receiving element is provided at the muzzle portion of the gun. At the same time when the player pulls the gun trigger, the screen displayed on the CRT switches from the game screen to the white screen for position detection (hereinafter referred to as the flash screen), and raster scanning of the flash screen starts from the upper left corner of the CRT as the starting point. To be done. Then, at the same time that the raster scan in the muzzle direction of the gun is performed,
Light from a raster scanning screen was detected by a light receiving element provided on the gun, and the X and Y coordinates of the raster scanning position were detected as the landing position.

[0004]

However, in the conventional shooting game device, when the player holds the gun toward the game screen, the aiming position detected by the light receiving element and the position aimed by the player (the player There is a problem that, if a deviation occurs between the actual aiming position), this deviation cannot be corrected.

That is, when shooting with a gun having a blowback generating mechanism on the barrel,
The light-receiving element that detects the aiming position is often provided below the barrel. Therefore, when the player holds the gun toward the target on the screen, the light receiving element detects a position below the position aimed by the player as the aiming position. Also, the positional deviation between the position where the player actually aimed and the aiming position detected by the light receiving element is
In addition to this, it is also caused by variations in the assembly accuracy of the gun itself, variations in the performance of the display itself, and other causes.

However, in the conventional game device which detects the aiming position by using the light receiving element, there is no means for correcting the deviation between the aiming position detected by the light receiving element and the position aimed by the player. For this reason, if the player feels uncomfortable that he or she does not aim at the position he or she is aiming for, there is a problem that the player cannot accurately aim at the targets displayed one after another on the screen.

This problem is not so serious in the conventional game device that can detect the landing position on the game screen very roughly, but it was developed so that the landing position can be detected very accurately. In such a game device, the player who plays the game feels uncomfortable and becomes a major factor of reducing the fun of the game.

The present invention has been made in view of the above problems, and an object thereof is to correct the positional deviation between the aiming position on the screen detected by using the light receiving element and the position aimed by the player. , Providing a shooting type game device that enables a highly accurate shooting game.

[0009]

In order to achieve the above object, the invention of claim 1 calculates a shooting game screen when the game mode is set, and when the correction mode is set, a correction screen including a position correction target. A game calculation means for displaying, a raster scanning type display means for displaying a calculated screen, a gun means for shooting on the screen, and a sighting position of the gun means on the screen. The position detecting means includes a position detecting means and an aiming position correcting means for correcting an aiming position. The position detecting means is provided in the gun means and detects a light from a direction in which the gun faces, and the light receiving part. Position calculating means for obtaining the horizontal and vertical reference aiming positions on the screen as X and Y coordinates based on the horizontal and vertical raster scanning positions at the time of detecting the received light The aiming position correcting means includes a mode changing means for changing the mode of the game calculating means, and the reference aiming means when the gun means is aimed at the position correcting target of the correction screen when the correction mode is set. Based on the position and the display position of the position correction target,
Correction distance calculation means for calculating and setting the position correction distances ΔX and ΔY in the horizontal and vertical directions, and the position calculation means, when setting the game mode, the X and Y coordinates of the reference aiming position, It is characterized in that X-coordinates and Y-coordinates representing the corrected aiming positions in the horizontal and vertical directions on the screen are obtained based on the position correction distances ΔX and ΔY.

With the above arrangement, when the operator sets the game calculation means to the correction mode, the display means displays the correction screen including the position correction target.

At this time, when the gun means is aimed at the position correcting target on the correction screen, the correction distance calculating means sets the uncorrected aiming position calculated by the position calculating means based on the detection signal of the light receiving section as the reference aiming position. The horizontal and vertical position correction distances ΔX and ΔY are calculated and set based on this reference aiming position and the display position of the position correcting target.

After that, when the game mode is set, the position calculation means calculates the position based on the reference aiming position calculated based on the detection signal of the light receiving section and the position correction distance.
The X-coordinate and the Y-coordinate representing the corrected aiming position on the screen used for hit discrimination and the like are determined. As a result, the position aimed by the player and the aiming position match each other, and the player can enjoy the shooting game without discomfort.

In particular, in a game device capable of accurately detecting the aiming position, the correction is performed so that a sensory deviation does not occur between the aiming position and the position aimed by the player as in the present invention. It becomes important to do. This allows
The player can proceed with the game while accurately aiming at the target appearing on the screen, and it is possible to realize a shooting type game device that can be widely enjoyed by beginners to advanced players.

Here, according to the invention of claim 2,
The correction distance calculation means calculates the horizontal and vertical distances between the reference aiming position and the display position of the position correction target when the trigger of the gun means is operated when the correction mode is set. The feature is that the calculation is set as the distances ΔX and ΔY.

In this way, as in the case of actually playing the game, the target is aimed, and the aiming position is corrected so that the target position becomes the aiming position. The occurrence can be better prevented.

According to the invention of claim 3, the game calculation means is formed so as to move and display an aiming mark from the reference aiming position toward the position correcting target when the correction mode is set, and the correcting distance is set. The calculating means calculates the horizontal and vertical distances between the reference aiming position and the display position of the aiming mark when the trigger of the gun means is operated when the correction mode is set, and the position correcting distances ΔX and ΔY. The calculation is set as

As described above, when the operator holds the gun means toward the position correcting target, the aiming marks are sequentially moved and displayed from the reference aiming position calculated by the detection signal of the light receiving section toward the position correcting target. . At this time, the operator may operate the trigger of the gun means when the aiming mark coincides with the aimed position correcting target. As a result, the distances in the horizontal and vertical directions between the reference aiming position and the display position of the position correction target become the position correction distance Δ.
The calculation is set as X and ΔY.

In particular, with such a structure in which the aiming mark is moved and displayed, it is possible to visually indicate to the operator that the aiming position is being corrected, and the aiming mark is corrected in position. By operating the trigger when the target is matched, the operator can visually confirm that the correction of the misalignment of the sight is completed.

Further, according to the invention of claim 4, the correction distance calculating means sets an upper limit value to the position correction distances ΔX and ΔY.

It is preferable that the upper limit value is set to be slightly larger than the deviation width of the aiming position that can normally occur in the game device. This prevents the occurrence of a situation in which the corrected aiming position exists outside the screen when the player holds the gun means toward the screen because ΔX and ΔY are set unnecessarily large. be able to.

In particular, when the gun means is held toward the screen, if the corrected aiming position is out of the screen and no aiming mark appears at all, the cause is that the position correction distance is set incorrectly. It is not possible to properly determine whether or not there is a failure in the machine, which causes a problem in performing maintenance of the game device. According to the invention of claim 4, it is possible to prevent such a situation from occurring. Can be prevented.

According to the invention of claim 5, the game calculation means is formed to display an aiming mark at the correction aiming position of the correction screen when the trigger of the gun means is operated when the correction mode is set. It is characterized by that.

With the above arrangement, the operator can visually confirm the corrected aiming position, so that the aiming position can be corrected more reliably.

When a coin is inserted and the start buttons 18a and 18b are operated, a two-player shooting game for multiplayer is started. Then, the player P holds the gun 20 and the display 1
Moving to 2, the game screen is displayed on the display 12. The player can enjoy the shooting game by aiming at the targets displayed one after another on the game screen and operating the trigger button.

A door 15 that is closed in a locked state is provided on the front surface of the housing 10. When a game center manager or the like opens the door 15 with a predetermined key,
The mode switching button 17 provided inside can be operated. The mode switching button 17 is formed so as to switch the game device between the correction mode and the game mode.

When the game device is set to the game mode using the mode switching button 17, the game device is controlled so that a normal game is played. When the game device is set to the correction mode, a correction screen is displayed on the display 12 and the game device is controlled so that the aiming positions of the guns 20a and 20b are corrected.

FIG. 2 shows a circuit configuration of the shooting game apparatus of the embodiment.

When the shooting mode of the embodiment is set to the game mode, the game calculation control circuit 40 calculates game screens in which targets appear one after another according to a predetermined game program, and displays the screens on the display 12.

When the player shoots this target with the gun 20, the landing position is detected using the position calculation control circuit 30 functioning as position detecting means and displayed on the display 12. Then, when the position of the impact point and the position of the target match, it is determined that the bullet has hit, and the score corresponding to this target is counted and displayed as an image together with the screen where the target flew.

Therefore, the player can visually enjoy whether or not the aimed target is hit, and further enjoy the game while seeing his score displayed in real time.

The gun 20 is constructed so that when the trigger 26 is operated, the blowback generator 28 produces a recoil similar to that of an actual gun.

In order to detect the landing position, in the gun 20 of the embodiment, the barrel is formed in a hollow shape, a lens 22 is provided at the tip of the barrel, and a light receiving sensor 24 is provided at the back of the barrel 22 to emit light 110 from the direction of the barrel. The light receiving sensor 24 is used for detection. At this time, the light receiving sensor 24 is
When the gun is held at the reference position, a detection area 200 having a diameter of about 5 cm is set on the display 12 as shown in FIG. And display 12
When the raster scan of passes through the detection area 200, the light receiving sensor 24 outputs a detection pulse to the position calculation control circuit 3
Output to 0.

When the player aims at the target and operates the trigger 26, the trigger signal is input to the game calculation control circuit 40 through the position calculation control circuit 30, whereby the game calculation control circuit 40 positions the display 12. Flush for detection. Then, when this flash screen is displayed, the position calculation control circuit 30 determines, based on the horizontal and vertical raster scan positions when the detection pulse is input from the light receiving sensor 24, the X and Y coordinates indicating the landing position on the screen. Is detected, the game calculation control circuit 40
To enter. The game calculation control circuit 40 is configured to determine whether or not the landing position matches the hit area of the target, and perform a hit game effect or a miss game effect.

FIG. 4 and FIG. 5 schematically show the principle of highly accurate aiming position detection used in the apparatus of this embodiment.

As shown in FIG. 4, the light receiving sensor 24 of the embodiment
Has a circular detection area 200. Therefore, when the gun 20 is held toward the display 12, the detection area 200 of the light receiving sensor 24 is set on the display 12 facing the barrel as shown in FIG.
The diameter of the detection area 200 is, for example, about 5 cm when the gun is held at the reference position, but the value changes depending on the position where the gun is held. Then, when raster display scanning is performed in the detection area 200, the light receiving sensor 24 detects this light and outputs a detection pulse to the position calculation control circuit 30.

If the light receiving sensor 24 has an extremely high detection sensitivity, as shown in FIG. 4, the detection pulse is detected at the time when the initial horizontal scanning 100-1 intersecting the detection area 200 is performed. It should output. However, the actual light receiving sensor 24 cannot output the detection pulse unless it receives a certain amount of light or more, and therefore 10
The amount of received light is insufficient and the detection pulse cannot be output only by performing the initial horizontal scanning shown in the area 0-1.

When horizontal scanning of a plurality of lines crossing the detection area 200 is performed, the energy in the detection area 200 is detected by the light receiving sensor due to the afterglow effect of the display, the output delay characteristic of the detection sensor 24, and the like. When the horizontal scanning 100-2 intersecting with the detection area 200 is performed at that time, the amount of light required to be turned on is accumulated, and the detection pulse shown in FIG. To be done. However, the position at which this detection pulse is output is not constant, and differs at each detection. That is, the first pulse output from the light receiving sensor 24 is generated in the vicinity of the energy close to the threshold value required for turning on the light receiving sensor 24, and therefore the output timing thereof greatly varies. Therefore, when the X coordinate of the landing position is detected based on the output timing of the first pulse, it is unavoidable that the detected position varies in d. This is the cause of the conventional landing position detection error.

In the present embodiment, the X coordinate of the aim is determined based on the second and subsequent detection pulses output from the light receiving sensor 24. Here, based on the output timing of the detection pulse output second, the aiming X
It is configured to determine a coordinate position. In addition to this, for example, the average value of the x-coordinates obtained based on the output timings of the second and third detection pulses may be used as the aiming x-coordinate position.

That is, if the first detection pulse is output from the light receiving sensor 24, the next horizontal scanning 1
When 00-3 is performed, energy is accumulated on the screen in the detection area 200 to a level close to the light amount necessary for turning on the light receiving sensor due to the afterglow effect of the monitor, the output delay characteristic of the detection sensor 24, and the like. There is. Therefore, at the same time when the horizontal scan 100-3 passes through the detection area 200,
The second detection pulse is output from the light receiving sensor 24 at the position, and the output timing of the second detection pulse becomes extremely stable. Therefore, this second
By obtaining the X-coordinate of the aim based on the output timing of the detection pulse, the aim position of the gun 20 can be accurately obtained without variation.

FIG. 5 shows various waveform patterns output from the light receiving sensor 24. Waveforms I to III
Is a normal output waveform.

In waveforms I and II, the last detection pulse is output when 100-4 horizontal scanning is performed, and thereafter, even if horizontal scanning intersecting the detection area 200 is performed, the detection pulse is detected. Is not output. This is 100
After the horizontal scanning of -4, the afterglow effect in the detection area 200 fades and the amount of energy accumulated decreases, and even if the subsequent horizontal scanning is performed, the light energy sufficient to turn on the light receiving sensor 24. Because you will not be able to get

The waveform III is a waveform in the case where the afterglow effect of the display is sufficient and the detection pulse is continuously output for a while even if the horizontal scanning crossing the detection area 200 is not performed.

In the waveforms IV and V, the afterglow effect of the display is sufficiently large, and when the light receiving sensor 24 is saturated and the light receiving sensor 24 outputs the first detection pulse, the detection pulse is not turned off thereafter. 5 or 100
This is a case where the switch continues to be turned on until the horizontal scanning of -6 is performed. In this case, since the detection sensor 24 has already received a sufficient amount of light at the time of outputting the first detection pulse, the output timing of the first detection pulse is often stable. It has been confirmed that even if the x-coordinate position is detected based on this, a measurement error hardly occurs. In this case, the output timing of the second detection pulse is rather unstable.

Therefore, in the system of the embodiment, when the time difference between the output of the first detection pulse and the output of the second detection pulse is the predetermined reference value or more (in the case of waveform V), or the output of the second detection pulse is not detected. In the case (waveform IV), the X coordinate position of the aim is determined based on the output timing of the first detection pulse. By doing so, the aiming position can be detected more accurately.

In FIG. 3, the player has a game screen 200.
The gun 20 is pointed toward and is schematically shown aiming at a game target 210. The aiming position 300 'at which the player aims at the game target 210 is
It is set by aligning the sight line with the sight 21 provided above the barrel of the gun 20. That is, the position 300 'aimed by the player exists on the extension line of the sights 21, 21 provided on the barrel. Therefore, this position 3
If 00 'and the aiming position 300 detected by the sensor 24 do not match, the player feels uncomfortable that the aiming position is not at the position aimed at him / her, and there is a problem that the game is less interesting.

Particularly, in the game device of the embodiment, which is improved so as to accurately detect the landing position, the position 300 'aimed by the player and the detected aiming position 300
The positional deviation between and becomes a major factor that impairs the fun of the game.

Therefore, in the game device of the embodiment, a manager such as a game center opens the door 15 shown in FIG. 1 by using a predetermined key and operates the mode switching button 17 to set the game device to the game mode. It is formed so that it can be switched and set to the correction mode.

When the game device is set to the correction mode, the game calculation control circuit 40 causes the display 12 to operate.
The position correction screen 250 shown in FIG. 6 is displayed above.

The position correction screen 250 is formed so that a correction target area 260 surrounded by a pair of left and right arrows is displayed at the center of the screen as a position correction target. The central coordinate position of the correction target area 260 is set to Q
= (Xc, Yc).

Then, the operator selects the correction target area 2
Positioning the gun 20 toward 60, the position calculation control circuit 3
0 calculates the pre-correction aiming position as the reference aiming position based on the detection pulse of the detection sensor 24, and the aiming mark 300 is displayed at the reference aiming position on the screen 250. This reference aiming position is P '= (X', Y ').

Therefore, the distance between Q and P'is displaced from the reference aiming position of the position 300 'aimed by the operator.

When the operator operates the trigger 26 of the gun 20 in this state, the position calculation control circuit 30 functions as a correction distance calculation means, and the position Q of the target area 260 and the X-axis of the reference aiming position P ', The distances in the Y-axis direction are set as the position correction distances ΔX and ΔY and calculated and set according to the following equation.

ΔX = Xc−X ′ ΔY = Yc−Y ′ (1) When the position correction distances ΔX and ΔY are set in this way, the position calculation control circuit 30 detects Reference aiming position P ′ = (X ′, Y ′) obtained from the detection pulse of the sensor 24
From the above, a correction calculation formula for obtaining the aiming position P = (X, Y) for displaying the aiming mark is set as shown by the following formula.

X = X ′ + ΔX Y = Y ′ + ΔY (2) When the setting of the correction calculation formula for obtaining the aiming position P is completed in this way, the game calculation unit 42 displays the correction screen. Then, the correction target area 260 surrounded by a pair of left and right arrows is deleted, and instead, the aiming mark 300 is displayed at the correction aiming position calculated using the formula (2) in the correction screen. Thereby, the operator can confirm whether or not the aiming position is appropriately corrected based on whether or not the aiming mark 300 exists on the extension line of the aiming points 21 and 21 provided on the barrel. . Then, when it is determined that it is not appropriate, the aiming position correction operation described above may be performed again. When it is determined that it is appropriate, the mode switching button 17 is operated again to bring the game apparatus out of the correction mode. After switching to the game mode, the door 15 is closed and locked.

As a result, the position calculation control circuit 30 accurately corrects the aiming position of each gun 20 based on the equation (2) and outputs it to the game calculation section 42. It is possible to enjoy a shooting game without feeling the positional deviation between the aimed position 300 ′ and the detected aiming position 300.

In particular, in this embodiment, the landing position can be accurately detected in millimeters, and the deviation between the position 300 'aimed by the player and the position 300 detected by the sensor 24 is also in millimeters. Because it can be corrected,
It is possible to perform a game effect that requires the player to shoot accurately, and it is possible to realize a shooting game device that can be enjoyed by a wide range of players from beginners to advanced players. Further, when the operator mistakenly aims the outside of the screen 250 and operates the trigger in the correction mode setting shown in FIG. 6, ΔX and ΔY become too large, and the aiming mark 300 is displayed in the screen 250. It may not be displayed. In this state, when the game device is set to the play mode, even if the player shoots a gun toward the screen 250, the landing mark does not appear on the screen at all. In such a case, the cause is ΔX,
It is not possible to properly determine whether there is a setting error of ΔY or a machine failure, which causes a problem in maintaining the game device. In this embodiment, in order to prevent such a situation from occurring, the upper limit value ΔXma is added to the ΔX and ΔY.
x and ΔYmax are set. This ΔXmax, ΔY
It is preferable to set max to be slightly larger than the deviation width of the aiming position that actually occurs on the game device.

FIG. 7 shows a specific circuit configuration of the game apparatus of this embodiment, and FIG. 8 shows a more specific configuration of the position detection unit 60 shown in FIG.

The game calculation control circuit 40 includes a game calculation section 42 for calculating a game screen and a correction screen, an image forming section 44 for displaying the calculated screen on the display 12, and a sound corresponding to the game development. Signal to speaker 50
And a voice synthesizing unit 46 for synthesizing and outputting

The game calculation section 42 is configured to be switched between the game mode and the correction mode by the mode switching button 17. Then, when the correction mode is set, the position correction screen 250 as shown in FIG. 6 is calculated,
This is displayed on the display 12. Further, when the game mode is set, the game is started based on the progress from the operation section 11 such as the start buttons 18a and 18b, and the game screen is calculated based on a predetermined game program and displayed on the display 12. There is.

The position calculation control circuit 30 comprises a position calculation section 60 and a correction distance calculation section 70.

The position calculation unit 60 includes an X counter 62, a Y counter 64, and a position determination unit 66 shown in FIG.

Hereinafter, the structure of the position calculation control circuit 30 will be described separately for the case where the game device is set to the correction mode and the case where the game device is set to the game mode.

First, the case where the game device is set in the correction mode will be described.

FIG. 9 shows an operation flowchart of the game calculation control circuit 30 in this case.

First, the operator selects the mode switching button 17
When the game device is set to the correction mode by operating (step S10), the position correction screen 250 shown in FIG. 6 is displayed on the display 12 (step S12).

In this state, the player makes a correction screen 25.
It is assumed that the aiming mark 300 is displayed at the reference aiming position P ′ detected by the detection sensor 24 when the gun 20 is aimed at the correction target area 260 of 0.

At this time, the game device of the embodiment repeats the series of operations of steps S14 and S18 to 32 until the trigger of the gun 20 is operated.

First, in step S14, the light receiving sensor 2
Based on the detection output of No. 4, the actual aiming coordinate data P '= (X', Y ') is obtained as follows.

The Y counter 64 counts the number of horizontal scans currently being performed for each screen scan, and outputs the count value to the position determining unit 66 as Y coordinate data.

The X counter 62 increments the value by one each time the horizontal scanning advances by one pixel, and outputs the value to the position determining section 66 as the X coordinate position of the raster scanning. The value of the X counter 62 is reset each time each horizontal scanning is completed.

When the first detection pulse is output from the light receiving sensor 24, the position determining section 66 latches the value of the Y counter 64 at that timing as the Y coordinate representing the vertical position of the aim. Further, the position determining section 66 latches the output of the X counter 62 as the first X coordinate XT at the same time when the first detection pulse is output.

Then, the position determining section 66 determines that the light receiving sensor 2
When the second detection pulse or is input from 4, the count value output from the X counter 62 at that time is changed to the second X
Latch as coordinate XS.

Further, the position determining section 66 is arranged to
If the output time difference between the detection pulse and the second detection pulse is within a predetermined reference value (for example, within a time corresponding to one horizontal scanning), it is determined that the second X coordinate XS is valid, and the latched Y coordinate, The second X coordinate XS is determined as the reference aiming position, and its coordinate data (XS, Y) is directed to the game calculation unit 40 and the correction distance calculation unit 70 as the reference aiming position data P '= (X', Y '). Output.

The position determining section 66 outputs the first detection pulse but does not output the second detection pulse when the output time difference between the first detection pulse and the second detection pulse is equal to or larger than a predetermined reference value. In such a case, it is determined that the first detection pulse XT is an effective X coordinate, the latched Y coordinate and the first detection pulse XT are adopted as coordinate data representing the aiming position, and the coordinate data (XT, Y) as reference aiming position data P ′ = (X ′, Y ′) is output to the game calculation unit 40 and the corrected distance calculation unit 70.

As a result, the game calculation section 24 displays the aiming mark 300 at the position of the input reference aiming position data P '= (X', Y '), as shown in FIG.

Next, in steps S18 to S32, the correction distance calculation unit 70 calculates and sets the position correction distances ΔX and ΔY.

First, in step S18, the correction distance calculation unit 70 sets the coordinate position Q = of the correction target area 260.
(Xc, Yc) and the calculated reference aiming position P ′ =
Based on (X ', Y'), the position correction distances ΔX, ΔY are calculated using the equation (1).

Next, according to the flow of steps S22 to S32, the final position adjustment distance is calculated and set.

At step S22, ΔX is ΔXmax.
It is judged whether or not it is smaller, and when it is judged that it is smaller, ΔX is used as it is for the position correction distance ΔX in the X-axis direction.
(Step 24), and when it is determined to be large, ΔXmax is used as the position correction distance ΔX in the X-axis direction (step S26).

Similarly, in step S28, ΔY is
It is judged whether or not it is smaller than ΔYmax. If it is judged to be smaller, ΔY is used as it is as the position correction distance in the Y-axis direction (step S30), and if judged to be larger, ΔYmax. Is used as the position correction distance ΔX (step S32).

In this way, the correction distance calculation unit 710 of the embodiment determines the position correction distances ΔX and ΔY representing the deviation between the coordinate position Q of the correction target area 260 and the reference aiming position P ′. The determined correction distances ΔX and ΔY are calculated by the position calculation unit 60.
Output to.

When the operator operates the trigger of the gun 20 (step S20), steps S18 to S3 are performed.
Position correction distances ΔX, ΔY obtained according to the flow of FIG.
Using, the position calculation unit 60 sets the correction calculation formula shown in the formula (2). Then, the game calculation unit 42 deletes the correction target area 260 enclosed by a pair of left and right arrows from the correction screen 250, and instead, the correction aim calculated using the formula (2) in the correction screen 250. The aiming mark 300 is displayed at the position (step S34).

When the operator who sees this correction screen determines that the aiming position is properly corrected, he or she operates the mode switching button 17 to switch the game device from the correction mode to the game mode. As a result, the aiming position data P = (X, Y) corrected and calculated based on the equation (2) is output to the game calculating section 42, and the position aimed by the player and the aiming position are equal to each other. Therefore, it is possible to allow the player to play the shooting game without feeling uncomfortable.

The present invention is not limited to the above embodiment, and various modifications can be made within the scope of the gist of the present invention.

For example, in the above-described embodiment, the case where the aiming mark 300 is displayed at the reference aiming position detected by the detection sensor 24 on the correction screen 250 when the correction mode is set has been described as an example. , The purpose can be achieved without displaying the aiming mark. In addition, initially, the aiming mark 300 is displayed at a position corrected in advance by a predetermined distance,
After setting the position correction distance, the aiming mark 300 may be displayed at the position corrected by the set distance. In addition to this, the aiming mark 30 is attached to the aiming position P that has been previously corrected.
You may make it display 0. As a result, it is possible to visually determine whether or not the current corrected aiming position P is appropriate, and perform the next aiming position correction.

In the above embodiment, the case where the aiming mark 300 is fixedly displayed at the reference aiming position P'on the correction screen 250 when the correction mode is set has been described.
The present invention is not limited to this, and for example, the game calculation unit 42 may be formed to move and display the aiming mark 300 from the reference aiming position P ′ toward the correction target area 260 when the correction mode is set. In this case, the correction distance calculation unit 70
Is the reference aiming position P ′ when the trigger of the gun 20 is operated.
And the horizontal and vertical distances from the display position P2 ′ of the aiming mark 300 may be calculated and set as the position correction distances ΔX and ΔY.

With this configuration, when the aiming mark 300 coincides with the aimed correction target area 260, the trigger of the gun 20 is operated to adjust the position as described above. The distances ΔX and ΔY are set.

In particular, by adopting such a configuration in which the aiming mark 300 is moved and displayed, it is possible to visually instruct the operator that the aiming position is currently being corrected, and the aiming mark 300 is corrected. By operating the trigger when it matches the target area 260 for
The operator can be made aware that the correction of the positional deviation of the sight is completed.
