Detailed Description
Preferred embodiments of the present invention will be described with reference to the accompanying drawings. In addition, in the respective drawings, components denoted by the same reference numerals have the same or similar configurations.
< overall construction >
Fig. 1 is an external perspective view of the dart game apparatus in the present embodiment. As shown in fig. 1, the dart game apparatus 10 is formed in a shape of, for example, a vertical rectangular parallelepiped. The dart game apparatus 10 provides a game of darts to a player, for example, one player throws three darts continuously in one round or the like. The dart is not particularly limited to a soft dart, a hard dart, or the like.
The dart game apparatus 10 includes a dart board 12 and a display device 14. The dart board 12 is disposed on the front surface of the dart game device 10 at a substantially line-of-sight position when the player is in a standing posture. The display device 14 displays a still image or a moving image.
In addition, a coin slot, a mode selection switch, and the like are provided on the front surface of the dart game apparatus 10. The player inserts the fee into the coin slot, presses the mode selection switch, and selects the game mode to play the dart game. In this dart game, a player stands at a predetermined position in front of the dart game device 10, and throws darts while aiming at a predetermined target on the dart board 12. When the dart that reaches the dart board 12 is a hard dart, the tip thereof is made of resin when the dart board 12 is pierced by the tip thereof, and when the dart board 12 is a soft dart, a plurality of holes (not shown) are formed in the target 18 of the dart board 12 so that the darts are pierced and engaged with each other, and therefore, when the darts engage with the holes (hereinafter, these are collectively referred to as "dart-pierced dart board or the like"), the coordinate positions of the darts such as the darts are detected, and a score is displayed on the display device 14 based on the positions of the darts such as the darts that are pierced.
Fig. 2 is a front view of dart board 12. The speed sensor 16 is attached to the upper left side of the dartboard 12, measures the speed of the surrounding object, and outputs speed data indicating the measured object speed. Note that the mounting position of the speed sensor 16 is not limited to the position in fig. 2. The device can be installed at any position as long as the speed of the dart can be measured.
The target 18 is divided into a plurality of segments having different scores, and a displacement sensor 22 (segment sensor) for detecting which of the plurality of segments is pressed is attached to the rear surface of the target 18.
An impact sensor 20 that detects an impact applied to the dartboard 12 is attached to the dartboard 12. For example, as shown in fig. 2, the impact sensors 20 are attached to four positions, i.e., the upper and lower positions, and the left and right positions, substantially at the center of the dart board 12.
As the position detection sensor 24, a plurality of light sources 24A attached around the dart board 12 and a plurality of light sensors 24B for detecting the light intensity of light emitted from the light sources are mounted. For example, as shown in fig. 2, the light source 24A and the light sensor 24B are attached to the upper and lower sides of the substantial center of the dart board 12 and the vicinity of the four corners, but the number and the number are not limited to these positions.
< hardware construction >
Fig. 3 is a diagram showing an example of the hardware configuration of the dart game apparatus 10. The dart game apparatus 10 includes: a display device 14, a speed sensor 16, an impact sensor 20, a hit detection sensor (displacement sensor 22, position detection sensor 24), an operation device 26, a target camera 27, a player camera 28, an input/output interface 29, and a control device 30. Further, in the dart game apparatus 10, for example, the speed sensor 16, the target camera 27, the player camera 28, or the input/output interface 29 can be appropriately selected to be included. The control device 30 includes a CPU32 and a memory 34 that control the entire system.
When the power supply of the dart game device 10 is turned on, the CPU32 reads the game program in accordance with the startup program stored in the memory 34, and outputs a game screen to the display device 14. Further, the player is caused to perform a desired play mode by a coin-in signal from the operating device 26, a selection switch, an input signal from a start switch, and the like.
The speed sensor 16 is a sensor provided on the dartboard and outputs speed data indicating the speed of the object to be measured. For example, the speed sensor 16 may be a sensor that discretely outputs speed data indicating the speed of the object detected by the speed sensor 16.
The speed sensor 16 may be, for example, a doppler sensor, and may be mounted to the dart board 12 so that microwaves are emitted to a space between the player and the dart game apparatus 10. The velocity sensor 16 detects the velocity of the object using the difference between the frequency of the transmitted microwave and the frequency of the microwave reflected from the moving object.
The impact sensor 20 detects an impact applied to the dart board. The impact sensor 20 is used, for example, to detect that a dart hits any position in the entire dart board 12. In the displacement sensor 22, if the dart misses the target 18, the dart hit cannot be detected, but in the case of the impact sensor 20, even if the dart hits a position deviated from the target 18, the dart hit can be detected.
The displacement sensor 22 is a sensor for detecting the hitting of an object by measuring the rearward displacement of the target 18 of the dart board. The displacement sensor 22 is, for example, a segment sensor provided for each segment and composed of a switch group. The segment sensor portion determines that the dart has penetrated a segment or the like by pressing a switch corresponding to the segment by a force applied when the dart penetrates the segment or the like. With this configuration, the displacement sensor 22 can detect which of the plurality of segments is pressed. The dart game apparatus 10 can determine the position where a dart has been stuck or the like simply in units of segments by having the displacement sensor 22.
The position detection sensor 24 detects that an object has hit by measuring the light intensity around the dart board. The position detection sensor 24 may be constituted by a plurality of light sources 24A and a plurality of light sensors 24B for detecting the light intensity of light emitted from the light sources. The dart game apparatus 10 can determine the position of the dart puncture target 18 and the like in more detail than in units of segments by including the position detection sensor 24.
Specifically, the position detection sensor 24 may also be: when the dart pierces the target 18, the dart shields light from the light source 24A so that the light and shade of light directed to the light sensor 24B change, at least two light sensors 24B detect the light and shade of the light, these detection signals are transmitted to the control device 30, and the direction of the shadow of the dart is determined based on the light and shade ("peak value" or "shadow of the dart") of the light from the outputs of the two light sensors 24B by the CPU32, respectively, and the location at which the dart is pierced is calculated using a triangulation method.
It is noted that the displacement sensor 22 and the position detection sensor 24 are both sensors that detect the object hitting a segment of the dartboard. The displacement sensor 22 and the position detection sensor 24 are collectively referred to as an on-target detection sensor. The hit detection sensor may be, for example, the displacement sensor 22, the position detection sensor 24, or both of them.
The target camera 27 is a camera for shooting the target of the dart board. The target camera 27 is provided so as to be able to take a picture of the dart hitting the target. The target camera 27 outputs the captured still image or moving image to the image analysis section 108.
The player camera 28 is a camera for photographing at least a part of the player. The player camera 28 is provided to be able to take a picture of a player (player) throwing a dart. The player camera 28 outputs the captured still image or moving image to the image analysis section 108.
The input/output interface 29 has a function of mediating information exchange with an external device. The external device is, for example, an input device such as a keyboard or a mouse, an output device for presenting information to the user, or a network such as the internet. The dart game apparatus 10 can communicate with various external apparatuses via the input/output interface 29.
< functional Block construction >
Fig. 4 is a diagram showing an example of the functional block configuration of the dart game apparatus 10. The dart game device 10 includes a game execution unit 100, a speed detection unit 102, an output unit 104, a cheating determination unit 106, and an image analysis unit 108. Further, in the dart game apparatus 10, the speed detection section 102 and the image analysis section 108 may be appropriately selected to be included.
The game execution unit 100, the speed detection unit 102, the output unit 104, the cheating determination unit 106, and the image analysis unit 108 can realize programs stored in the memory 34 by processing executed by the CPU 32. In addition, the program may be stored in a storage medium. The storage medium storing the program may be a non-transitory storage medium. The non-transitory storage medium is not particularly limited, and may be a storage medium such as a USB memory or a CD-ROM.
The game execution unit 100 has a function of performing various processes for executing a dart game. The various processes are, for example, the progress of a game mode selected by the player, the judgment of the dart hitting the dart board 12, the judgment of the position of the dart hitting the target 18 or the like, the calculation of a score, the animation display for playing a dart game, and the like.
The game execution unit 100 determines, as the time at which the dart hits the dart board 12, the time at which the displacement sensor 22 detects the rearward displacement of the target of the dart board 12 (for example, the time at which the pressing of any one of a plurality of segments included in the target is detected) or the time at which the position detection sensor 24 notifies the dart to hit the target 18, or the like. The game execution unit 100 may determine, for example, the time when the impact sensor 20 detects the impact as the time when the dart hits the dart board 12. When judging that the dart hits the dart board 12, the game execution unit 100 notifies the speed detection unit 102 that the dart has hit the dart board 12.
The speed detection unit 102 has a function of detecting the speed of a dart thrown by a player onto the dart board 12 using speed data indicating the received speed of an object, which is output from the speed sensor 16. The speed detection unit 102 may detect, as the speed of the dart, the speed data received from the speed sensor 16 during a period (hereinafter referred to as a "predetermined determination period") from a time when the game execution unit 100 determines that the dart hits the dart board 12 to a time before a predetermined time from the time (hereinafter referred to as a "predetermined determination period").
The speed sensor 16 includes, in addition to the speed of the dart, speed data detected by the motion of the player swinging an arm, speed data detected by reflection of microwaves on a person walking around the dart game apparatus 10, and the like, in the speed data output from the speed sensor 16.
The speed detection unit 102 may select speed data corresponding to the speed of the dart from among the speed data received from the speed sensor 16, as appropriate, based on the time at which the dart is determined to hit the dart board 12, from among one or more pieces of speed data received from the speed sensor 16 within a predetermined determination period. The speed detection unit 102 may determine, for example, the speed data received from the speed sensor 16 at the time closest to the determination as the speed data corresponding to the speed of the dart.
The predetermined determination period is a period from a time when the game execution unit 100 determines that the dart hits the dart board 12 to a time before a predetermined time (for example, 1 second, 0.5 second, or the like) from the time. Thus, the speed detection unit 102 determines the measurement data measured when the dart has recently hit the dart board 12 as the speed data corresponding to the speed of the dart, and therefore, it is possible to suppress erroneous determination of speed data that is not related to the speed of the dart, such as speed data detected by the motion of the player swinging an arm, as the speed data corresponding to the speed of the dart, and to detect the speed of the dart with higher accuracy.
The output unit 104 has a function of outputting the determination result of the game execution unit 100 or the cheating determination unit 106. The output unit 104 may output, for example, a dart speed detected by the speed detection unit 102, a result analyzed by the image analysis unit 108, or the like, in addition to the determination result. Here, "output" includes all output modes of output to each functional section, output to the input/output interface 29, output to the memory 34, output (display) to the display device 14, and the like.
The output unit 104 may output a cheating determination result of the cheating determination unit 106, for example, which will be described later. Specifically, the output unit 104 may output at least one of the following determination results (1) to (4) determined by the cheating determination unit 106: (1) outputting a throwing result of the game execution section 100 (for example, a result called a judgment that the dart hits the dart board 12, a judgment that the dart hits a position of the target 18 or the like, a score calculation, or the like; the same applies hereinafter); (2) outputting a cheating detection alarm indicating a warning that a cheating action was detected; (3) re-throwing the throwing, wherein the throwing result does not reflect anything; (4) as a result of the throw, "OUT" indicating that the dart missed the target 18 without scoring is output.
The display unit has a function of displaying the dart speed detected by the speed detection unit 102 on the display device 14.
The cheating determination unit 106 has a function of determining whether or not the player is likely to cheat. In other words, the cheating determination section 106 has a function of determining whether the player correctly throws darts. The cheating action performed by the player is an action in which the player presses the segment with his or her finger, or throws an object other than a dart such as a blown arrow, for example, so that the dart game device 10 makes an erroneous judgment as if the dart were thrown, although the dart was not actually thrown. The cheating act may include an act (hereinafter, referred to as "close shot") in which the player does not throw the dart from a correct predetermined position (throwing line) although the dart is actually thrown.
The cheating determining unit 106 may determine whether or not the impact sensor 20 is operating normally, for example, and may omit the determination of whether or not the first condition is satisfied when it is determined that the impact sensor is not operating normally. For example, the cheating determination unit 106 may determine that the impact sensor 20 is not operating normally when the impact sensor 20 does not output an impact value within the normal determination threshold time or when the output impact value is a default value (e.g., "0 (zero)"). The normal determination threshold time is a normal time when it is detected that the impact is applied to the dart board from the time when the hit detection sensor detects that the object hits the segment. With this configuration, when there is a possibility that the impact sensor 20 does not operate normally, the determination process can be omitted.
For example, when a condition (hereinafter, referred to as "second condition") that the time of the detection signal from the displacement sensor 22 is longer than a predetermined response time is satisfied, the cheating determining unit 106 may determine that the player has a possibility of cheating. The predetermined response time is a value for determining whether or not the time of the detection signal to be determined is the time of the detection signal caused by hitting an object including a dart in a cheating manner. A normal time threshold (for example, about 32 milliseconds) may be set when the thrown dart hits the target within a predetermined response time. With this configuration, it is possible to determine a cheating act that is clearly determined to be a finger press (the time for detecting the signal is significantly long) at an early stage.
For example, when the hit detection sensor detects that the object hits the segment, the cheating determination unit 106 determines that the player has a possibility of cheating if a condition (hereinafter, referred to as "first condition") that the impact value due to the impact detected by the impact sensor 20 is smaller than a predetermined impact value is satisfied. The predetermined impact value is a value for determining an impact value caused by hitting an object including a dart in a cheating manner. The predetermined impact value may be set to a threshold value of whether or not the target impact value is a hit target value caused by throwing a dart.
In a cheating action of hitting a target by pressing with a finger or the like, the target is hit by directly pressing a segment or the like with the finger, and therefore, compared with a case where a dart is thrown as usual, an impact applied to a dart board (particularly, outside the target) is small. Therefore, with the configuration of the cheating determining section 106, whether or not the cheating action has been performed can be determined by the impact value of the hit target caused by the pressing with the finger being smaller than the impact value of the hit target caused by the correct throwing of the dart.
For example, when a condition (hereinafter, referred to as a "third condition") that the speed of the object detected by the speed detection unit 102 is not within a predetermined range is satisfied, the cheating determination unit 106 determines that the player has a possibility of cheating. The predetermined range is a value indicating a normal speed range in which the speed of the determination target is caused by the dart being thrown from the hand of the player onto the dart board. For example, the upper limit value and/or the lower limit value of the normal speed range may be set within a predetermined range. With this configuration, for example, in the case where a dart is thrown using a tool such as a blowing arrow or the like or a dart is thrown by so-called baseball throwing, there is a possibility that an impact exceeding a predetermined impact value is applied to the dart board and the first condition is not satisfied, but even in this case, by detecting a speed exceeding the predetermined speed and satisfying the third condition, it is possible to detect such a behavior and determine it as a cheating behavior.
For example, the cheating determining unit 106 may determine that the player has a possibility of cheating when the analysis result of the image analyzing unit 108 satisfies a condition (hereinafter, referred to as "fourth condition") that the dart game is not correctly performed according to a predetermined criterion within the first predetermined time. The first predetermined time is a time during which a player who should throw a dart correctly into a predetermined area described later should exist in order to enable a dart game to be correctly performed. The first predetermined time may be, for example, a time such as a first fraction of a second (e.g., 1 second or 0.5 second) from the time when the dart impact on the target is detected.
With the above configuration, for example, when a player moves from the predetermined position and inserts darts directly into the targets to hit the targets, the player is analyzed as not being in the predetermined area, and the behavior can be detected and determined as a cheating behavior.
For example, when the analysis result of the image analysis unit 108 satisfies a condition (hereinafter, referred to as "fifth condition") that an object other than a dart is reflected in the captured image within the second predetermined time, the cheating determination unit 106 determines that the player has a possibility of cheating. The second prescribed time refers to a time when the dart should be reflected in the image in the case where the player correctly throws the dart. The second predetermined time may be set to a time of, for example, a fraction of a second (e.g., 1 second or 0.5 second) before and after the time when the dart is detected to hit the target.
With the above configuration, when an object other than a dart (for example, a hand, a finger, or the like of a player) is projected, a behavior in which the player inserts the dart directly into a target with a hand, or a behavior in which the player inserts the dart into a depth at which the target is not detected with a hand, such as a behavior in which the player presses the dart momentarily with a hand forcefully from behind and finally inserts the dart so that the target can be detected, and it is determined that the behavior is a cheating behavior.
For example, when determining that a cheating action is likely to be performed, the cheating determination unit 106 may update a cheating detection count indicating the number of times the cheating action is likely to be detected and determined. Specifically, the cheating determining unit 106 may update the cheating detection count by incrementing it.
The cheating determination unit 106 determines whether or not the cheating detection determination count is equal to or greater than a predetermined count (for example, a first predetermined number of times per game and a second predetermined number of times per round) for each game or each round, and determines at least one of the following (1) to (4): (1) outputting a throwing result (for example, a result called judgment that the dart hits the dart board, judgment that the dart hits the position of the target 18 or the like, score calculation, or the like, hereinafter the same); (2) outputting a cheating detection alarm indicating a warning that a cheating action was detected; (3) re-throwing the throwing, wherein the throwing result does not reflect anything; (4) as a result of the throw, "OUT" indicating that the dart missed the target 18 without scoring is output.
The cheating determining unit 106 is configured to perform the above (1) when the cheating detection determination count per game (hereinafter referred to as "cheating detection determination count (game)") is smaller than a first predetermined number of times, perform the above (2) and (3) when the cheating detection determination count per turn (hereinafter referred to as "cheating detection determination count (turn)") is smaller than a second predetermined number of times, and perform the above (4) when the cheating detection determination count (game) is equal to or larger than the first predetermined number of times and the cheating detection determination count per turn is equal to or larger than the second predetermined number of times, for example.
With the above configuration, the number of times of determining a cheating action can be increased, the target can be limited to a player who performs a cheating action a plurality of times, a result of "OUT" which does not score a score and is not thrown again can be output, and a determination result for suppressing the cheating action can be output.
When the cheating determination unit 106 determines that the player is likely to cheat, the game execution unit 100 may not calculate the score. Further, the game execution unit 100 may determine that the player has performed the cheating act without calculating the score when the cheating determination unit 106 determines that the number of times the player has performed the cheating act exceeds a predetermined number of times.
The image analysis section 108 has a function of analyzing a still image or a moving image. The image analysis unit 108 analyzes an image captured by a player camera, for example, and determines whether or not the dart game is correctly performed based on a predetermined criterion. The predetermined reference is a reference indicating that the dart game is correctly performed, and for example, a player (throwing number) who should throw a dart is a reference indicating that the dart is thrown from the vicinity of a predetermined position in front of the dart game device 10 as usual. Examples of a dart game that is not correctly played according to a predetermined reference include: in the captured image, a player, a character other than the player who throws the number, or the like is not present in a predetermined area of the captured image, or a character which is not the player who should throw the number is throwing a dart or the like. The predetermined region is a region in which a player can confirm the presence of a dart when the player throws the dart from the vicinity of a predetermined position in front of the dart game device 10. In addition, the area that the player may exist when throwing from the predetermined position may be appropriately set in the predetermined area.
The image analysis unit 108 may extract the feature of the captured image, for example, and may analyze whether or not the player throws a dart according to a predetermined reference in the image by matching the feature pattern indicating that the player throws a dart according to a predetermined reference registered in advance in the memory 34 or the like. For this analysis, a conventional technique such as person recognition may be used.
The image analysis unit 108 analyzes an image captured by the target camera, for example, and determines whether or not an object other than a dart is reflected in the image within a second predetermined time. The image analysis section 108 may analyze whether or not an object other than a dart is reflected in the image by extracting a feature of the captured image and matching the feature with a feature pattern representing at least a part of the dart, which is registered in advance in the memory 34 or the like, for example. For this analysis, conventional techniques such as image recognition may be used.

Fig. 5 to 8 are flowcharts showing an example of the operation of the dart game apparatus 10. The operation of the dart game apparatus 10 will be described with reference to fig. 5 to 8. This operation is repeated every time the dart is thrown. Note that the processing procedure described below is an example, and may be changed as appropriate.
Fig. 5 to 6 show an example of an operation of detecting and judging a cheating act using the hit detection sensor and the impact sensor 20, and the flowchart shown in fig. 5 and the flowchart shown in fig. 6 are connected to each other by a connector indicated by the same symbol.
The dart game device 10 detects that an object hits the target of the dart board (step S10).
The dart game device 10 determines whether or not a second condition that the time of the detection signal from the displacement sensor 22 is longer than a predetermined response time is satisfied (step S11).
When the second condition that the time of the detection signal from the displacement sensor 22 is longer than the predetermined response time is not satisfied (no in step S11), the dart game device 10 determines whether or not the impact sensor 20 is operating normally (step S12).
When the dart game device 10 determines that the impact sensor 20 is operating normally (yes at step S12), it determines whether or not a first condition is satisfied that the impact value caused by the impact detected by the impact sensor 20 is smaller than a predetermined impact value (step S13). Further, when determining that the impact sensor 20 is not operating normally (no in step S12), the dart game device 10 does not determine whether the first condition is satisfied (step S13 is skipped and the execution is continued). The dart game device 10 continues to execute the flowchart of fig. 6 by the connector a.
When the dart game device 10 satisfies the second condition that the time of the detection signal from the displacement sensor 22 is longer than the predetermined response time (yes in step S11), or when the first condition that the impact value due to the impact detected by the impact sensor 20 is smaller than the predetermined impact value (yes in step S13), the cheating detection determination count (game) is updated (step S14). The dart game device 10 continues to execute the flowchart of fig. 6 by the connector B.
As shown in fig. 6, the dart game device 10 determines whether or not the updated cheating detection determination count (game) is equal to or greater than a first predetermined number of times (step S15).
When the updated cheating detection determination count (game) is equal to or greater than the first predetermined number of times (yes in step S15), the dart game device 10 updates the cheating detection determination count (round) (step S16).
When the first condition that the impact value due to the detected impact is smaller than the predetermined impact value is not satisfied (no in step S13 of fig. 5), the dart game device 10 outputs the throwing result (step S18).
The dart game device 10 determines whether or not the updated cheating detection determination count (round) is equal to or greater than a second predetermined number of times (step S17).
When the updated cheating detection determination count (round) is less than the second predetermined number of times (no in step S17), the dart game device 10 outputs a cheating detection alarm as a determination result of the cheating determination (step S19).
When the updated cheating detection determination count (round) is equal to or greater than the second predetermined number of times (yes in step S17), the dart game device 10 outputs the throw result as OUT as the determination result of the cheating determination (step S20).
When the updated cheating detection determination count (game) is less than the first predetermined number of times (no in step S15), the dart game device 10 outputs the thrown result as the determination result of the cheating determination (step S18).
Fig. 7 to 8 show an example of an operation of detecting and determining a cheating act using the speed sensor 16, the target camera 27, and the player camera 28 in addition to the hit detection sensor and the impact sensor 20. The flowchart shown in fig. 7 and the flowchart shown in fig. 8 are connected to each other by a connector denoted by the same symbol. Note that the processing procedure described below is an example, and may be changed as appropriate.
As shown in fig. 7, the dart game apparatus 10 photographs a player with the player camera 28 (step S30).
The dart game apparatus 10 measures the speed of the thrown object by the speed sensor 16, and outputs speed data indicating the measured speed of the object (step S31).
The dart game apparatus 10 photographs the target of the dart board with the target camera 27 (step S32).
The dart game apparatus 10 detects an impact applied to the dart board by the impact sensor 20 (step S33).
The dart game apparatus 10 detects the hit of an object on the segment of the dart board by the hit target detection sensor (step S34). Further, in steps S30 to S34, since each sensor independently senses, each of steps S30 to S34 may be partially or entirely performed in parallel or may be performed in sequence.
The dart game device 10 determines whether or not a second condition that the time of the detection signal from the displacement sensor 22 is longer than a predetermined response time is satisfied (step S35).
When the second condition that the time of the detection signal from the displacement sensor 22 is longer than the predetermined response time is not satisfied (no in step S35), the dart game device 10 determines whether or not the impact sensor 20 is operating normally (step S36).
When the dart game device 10 determines that the impact sensor 20 is operating normally (yes at step S36), it determines whether or not a first condition is satisfied that the impact value caused by the impact detected by the impact sensor 20 is smaller than a predetermined impact value (step S37). Further, when determining that the impact sensor 20 is not operating normally (no in step S36), the dart game device 10 does not determine whether the first condition is satisfied (step S37 is skipped and the execution is continued). The dart game device 10 continues to execute the flowchart of fig. 8 by the connector a.
If the dart game apparatus 10 satisfies the second condition that the time of the detection signal from the displacement sensor 22 is longer than the predetermined response time (yes in step S35) or the first condition that the impact value due to the impact detected by the impact sensor 20 is smaller than the predetermined impact value (yes in step S37), the flowchart of fig. 8 is continued by the connector B.
When it is determined that the impact sensor 20 is not operating normally (no in step S36), or when the first condition that the impact value due to the impact detected by the impact sensor 20 is smaller than the predetermined impact value is not satisfied (no in step S37), the dart game device 10 detects the speed of the object thrown onto the dart board by the player using the speed data received from the speed sensor 16 (step S38).
The dart game device 10 determines whether or not a third condition that the speed of the detected object is not included in the prescribed range is satisfied (step S39).
If the third condition is not satisfied (no at step S39), the dart game device 10 analyzes the captured image (step S40).
The dart game device 10 determines whether or not the result of the image analysis satisfies a fourth condition that the dart game is not correctly performed according to a predetermined criterion within the first predetermined time (step S41).
If the fourth condition is not satisfied (no in step S41), the dart game device 10 determines whether or not the result of the image analysis satisfies a fifth condition that objects other than darts are reflected within the second predetermined time (step S42).
If the fifth condition is not satisfied (no in step S42), the dart game device 10 outputs the throwing result (step S43).
When any of the third condition, the fourth condition, and the fifth condition is satisfied ("yes" in steps S39, S41, or S42), the dart game apparatus 10 determines that there is a possibility of a cheating action (step S44).
The dart game device 10 outputs the determination result (step S45).
Note that, in the present operation example, although an example has been described in which it is determined that there is a possibility of a cheating action if any one of the first condition, the second condition, the third condition, the fourth condition, and the fifth condition is satisfied, it may be determined that there is a possibility of a cheating action if at least any two or more of the first condition, the second condition, the third condition, the fourth condition, and the fifth condition are satisfied. For example, it may be determined that there is a possibility of a cheating action when two conditions, i.e., the first condition and the second condition, are satisfied, or it may be determined that there is a possibility of a cheating action when three conditions, i.e., the first condition, the third condition, and the fifth condition, are satisfied.
