1. First Embodiment Hereinafter, a discrimination system and a discrimination method of a game table to which an illegal apparatus according to the present invention is attached will be described in detail based on a preferred embodiment. FIG. 1 is a block diagram showing a first embodiment of a system for discriminating a game table to which an illegal apparatus according to the present invention is attached.

First embodiment of the amusement machine where the unauthorized device mounted in form determining system 1 (hereinafter, simply referred to as "determination system 1".) Is, gaming table 3 _-1 to the pachinko machines and pachislo stand like all of the holes It is installed in the hall computer (HC) 2 that manages 3- _n or is connected to the hall computer 2 as one device. In this case, communication between the discrimination system 1 and the hall computer 2 is performed using USB, LAN, or the like. The hall computer 2 manages all of the game stands installed in the hall, is installed in an office of a game store, etc., and communicates with the CPU, RAM, ROM, input/output section, display control section, and the outside. It is configured to include a communication control unit (none of which is shown) for controlling. Since the configuration of the hall computer 2 is well known, its explanation is omitted. In this embodiment, the discrimination system 1 is installed in the hall computer 2.

[Configuration of discrimination system 1]
Determination system 1 includes an image and a camera ₄ -1 _{to 4 -n} as photographing means for photographing the face of the player H, the image data of the face of the photographed player H by the camera ₄ -1 _{to 4 -n} An image processing unit 21 for processing, a face authentication means 23 for identifying the same person based on the face image data of the player H photographed by the cameras _4-1 to 4- _n , a hard disk drive or a solid state drive (Solid). (State drive) and each face image data of the player H generated by the image processing unit 21 and the machine numbers of the game machines _{3-1 to} 3- _n in which the player H is playing. Based on the player database (DB) 20 and the player database 20, which store information and the number of hits and the number of payouts at the game tables _{3-1 to} 3- _n in association with the face image data of the player H, respectively. The payout rate W, which is the ratio of the number of payouts to the number of shots at the gaming tables _{3-1 to} 3- _n played by the player H, is calculated, and the payout rate W of the player H having a predetermined rate or more is calculated. An average number-of-persons calculating means 24 for calculating the total number of persons for each of the game tables _{3-1 to} 3- _n and obtaining an average of the number of the players H having a predetermined payout rate W or more per one game table. The face authentication means 23 calculates the number of games P of each player H in the store based on the player database 20, the number of games P is less than a predetermined number, and the payout rate W is equal to or more than a predetermined ratio. a player extracting means 25 which extracts the player H was from the player database 20, a total number of players H extracted by the player extraction unit 25 has a game is calculated by the average number calculation detecting means 24 the average number greater gaming table 3 _-1 to 3 _-n than Q was provided with an illegal gaming table extraction unit 26 that extracts an illegal gaming table F. In addition, the discrimination system 1 includes an input device such as a keyboard and a mouse (not shown) for inputting various settings, and a display 5 for displaying various information and warnings. For example, when 26 is extracted as an illegal game table F, it is provided with a warning means 27 that warns the display 5.

The cameras _4-1 to 4- _n can use units used in digital cameras using CMOS sensors or the like, surveillance cameras, and the like, and have the capability of recording the face of the player H in high definition. However, if the number of pixels is 2 million pixels or more, there is no shortage. It should be noted that the cameras _4-1 to 4- _n may be installed anywhere as long as the face of the player H can be photographed. For example, the platform display lamp unit 7 shown in FIG. It can be installed in the inter-machine information terminal 9 shown in (b) (or the inter-machine machine 6 that accepts prepaid cards and cash and pays out game balls and medals). Then, the mounting angles of the cameras _4-1 to 4- _n are set to the photographing visual field θ as shown in FIG. In this case, the shooting visual field θ shown in FIG. 3B is set so that the entire face of the player H can be shot.

The image processing unit 21 is a program that performs processing such as noise removal, gradation correction, color correction, and image compression on face image data captured by the cameras _4-1 to 4- _n as necessary. Specifically, a face pattern based on contour lines and feature points and the like excluding the background and the like in the image is output, and this face pattern is stored in the player database 20.

Player database 20 is a relational database that in correspondence with the amusement machine 3 _-1 to 3 _-n saving the number of clicks and payout driving the player H of face image data. For example, stores the facial photograph of the player H to correspond to the amusement machine ₃ -1 _{to 3 -n} in field A, and stores the number of implantation in the gaming table ₃ -1 _{to 3 -n} in field B, and field C The number of payouts at the gaming tables _{3-1 to} 3- _n is stored. Note that the images taken by the cameras _4-1 to 4- _n are performed every one minute, as will be described later. Therefore, if the same face is continuously taken, it is determined that the same player H is playing the game during that time. However, the same face is stored redundantly, resulting in waste of storage capacity and enormous amount of image retrieval. Therefore, the number of saves in the player database 20 is also adjusted.

The face authentication means 23 extracts the face image data obtained by cutting out the face pattern in the face image of the predetermined player H photographed by the cameras _4-1 to 4- _n and the player H of the player H stored in the player database 20. It is composed of a program for comparing with face image data and determining whether or not a matching person exists. If they match, it is recognized as a player H who has visited the store in the past, and if they do not match, it is regarded as the first visitor. In addition to comparing the image data obtained by photographing the player H in the game with the face image data of the player H stored in the player database 20, the face image data of the player H stored in the player database 20 can be compared with each other. Also contrast. As a face recognition method, for example, a two-step process of face pattern cutout (=face detection) from an image and identification process is performed. First, if the face image data is f pixels×f pixels, it is vectorized into an f×f dimensional space (feature space). This vector representation then makes it possible to compare the two images. To what extent they are similar is determined based on the angle (correlation coefficient) formed by the vectors of the two. Specifically, the average face pattern generated from several face patterns is used as a template, the correlation with the input image (angle formed by two vectors) is obtained, and the region having the highest correlation value is extracted as the face pattern. In this way, the face is detected from the captured image.

Next, the identification processing for the detected face will be described. The most basic method of identification processing is the correlation method, and identification is performed based on the correlation (angle) between the input pattern and the registered pattern. The simplest identification method is to use the input grayscale image pattern as it is, but grayscale image information cannot be expected to have high discrimination performance because it is easily affected by illumination variations and the like. Therefore, the identification performance can be improved by extracting the features effective for identification from the grayscale image. In addition, a subspace method, which has higher performance than the correlation method, is also used. In this subspace method, discrimination is performed based on an angle formed by an input pattern vector and a subspace generated from a dictionary pattern using KL (Karhunen-Loeve) expansion. The face authentication method described above is an example, and the specific method is not limited to this, and it goes without saying that an appropriate method can be used.

The average number-of-players calculating means 24 calculates the payout rate W, which is the ratio of the number of payouts to the number of strikes at each of the game stands _{3-1 to} 3- _n played by each player H, based on the player database 20. The total number of players H whose ball rate W is equal to or higher than a predetermined rate is calculated for each of the gaming machines _{3-1 to} 3- _n , and the number of players H whose ball output rate is equal to or higher than the predetermined rate W is calculated. It consists of a program that calculates the average per gaming table. The payout rate W of each gaming table _{3-1 to} 3- _n is calculated from the number of hits and the number of payouts of each player H stored in the player database 20, respectively, and with respect to each gaming table _{3-1 to} 3- _n . The number of persons whose ball output rate W is equal to or higher than a predetermined rate is calculated. In this case, for example, if the payout rate W is 100% or more, it is possible to calculate the number of players H who have not been defeated at each of the gaming machines _{3-1 to} 3- _n . Then, the average number of persons whose payout rate W is equal to or higher than a predetermined rate is calculated for all the gaming machines _{3-1 to} 3- _n . Of course, by setting the payout rate W to 100% or more, it is possible to target the player H having a large profit.

The player extraction unit 25 selects the same player H from the face image data of each player H stored in the player database 20 by the face authentication unit 23, and the player H's previous game in the store. The number of times P is calculated based on the player database 20, the number of games P is less than a predetermined number, for example, less than 3, and the payout rate W is a predetermined rate, for example, 100% or more. It is composed of a program for extracting the player H from the player database 20. That patrons are repeatedly performed illegal at the same tempo is high risk, on the other hand, without hesitation if the unauthorized player G know in advance the gaming table 3 _-1 ~3 _-n mounted unauthorized devices It is considered that the game is played on the gaming tables _{3-1 to} 3- _n . Therefore, it is highly possible that the player H who is profitable or at least loses despite the small number of games P is playing on the gaming tables _{3-1 to} 3- _{n in} which some kind of fraud has been performed. Inferred. Therefore, the player extraction means 25 extracts a player H who is "P<predetermined number of times" and "the payout rate W>predetermined ratio". The predetermined number of games P is a number for distinguishing whether or not it is a regular customer, and it is not limited to three times, and can be set to an appropriate number of times such as four times, five times, or ten times. Further, it is preferable that the payout rate W is 100% or more, which does not cause a loss. The payout rate W may be based on the payout rate W for each of the game tables _{3-1 to} 3- _n played by the player H, or may be the average of the payout rate W of the player H. Good. That is, the player H may play the game twice, and the payout rate W may be 100% or more both times. The first time the payout rate W is 100% or more and the second payout rate W is 100% or more. When the ball rate is less than 100%, the average ball output rate W of two times may be 100% or more. Furthermore, by considering the game period, it is possible to add a period to the player extraction condition, for example, whether it is three times in a short period or three times in a long period.

Incorrect gaming table extraction unit 26, the player extraction means 25 Total number average number calculated out more than the average number Q calculated by means 24 gaming table 3 _-1 to 3 in which the player H extracted was game by _{- It} is composed of a program for extracting _n as an illegal gaming table F. That is, the player H extracted by the player extraction means 25 is less than the number of game number P is predetermined, and a player H payout ratio W was the predetermined ratio or more, there gaming table 3 _{- When the} number of players R played by _{1 to} 3 _−n by such a player H is at least larger than the average number of players Q calculated by the average number of players calculating means 24, the number of games P is small, It means that there are many players H having a high payout rate W, and it is presumed that such gaming machines _{3-1 to} 3- _n are unauthorized gaming machines F having a high possibility that an unauthorized device or the like is attached. be able to. The illegal game table extraction means 26 makes such a determination.

The warning means 27 warns the display 5 that such a gaming table _{3-1 to} 3- _n is found when the gaming table _{3-1 to} 3- _n is extracted by the illegal gaming table extracting means 26. It consists of a program to display. Specifically, in order to inform the employees of the hall that the gaming machines _{3-1 to} 3- _n have been discovered, the unauthorized gaming machine extraction means 26 extracts the gaming machines _{3-1 to} 3- _n . The unit number is displayed on the display 5 by pop-up or the like to warn the person concerned in the store. The warning can be issued by a method other than the display, for example, by outputting a message by voice synthesis and displaying a face image, displaying an alarm and a face image, displaying a character telop and a face image, and the like.

[First Discrimination Method and Operation of Discrimination System 1]
Next, a method (first determination method) for determining the gaming table to which the unauthorized device according to the present invention is attached will be described together with the operation of the determination system 1 described above. First, the fraudulent trick of a fraudulent person will be described with reference to FIG. FIG. 4 is a diagram illustrating a method of identifying a game table to which an unauthorized device is attached. Here, the amusement machine ₃ -1 _{to 3 -n} unauthorized attached to ROM (= bad ROM) includes a a payout probability of the game machine ₃ -1 _{to 3 -n} in which result in raising set uniformly Immediately, fraud is discovered when the hall computer 2 executes the counting process. Therefore, in general, the rogue ROM increases the probability of a ball being thrown out only under a specific condition set in advance by a rogue person (Goto ROM group), and in other cases, the probability that a rogue person has a ball out is increased. There is a technique to lower the probability (to restore it). The payout rate of the game machine thus crafted is programmed so as to fall within a predetermined probability on average. The discrimination system 1 is not limited to an unauthorized ROM, and can similarly determine an injustice such as “hanging” or “board exchange”.

In FIG. 4, it is assumed that, for example, five customers play in turn on a specific game table (=incorrect table) (the second game table from the left in FIG. 4) to which an illegal ROM is attached. At this time, in the fraudulent platform, the first illegitimate person operates the illegitimate ROM and wins 10,000 yen (that is, fraudulently wins). The person who operates the rogue ROM wins 10,000 yen, the fourth ordinary customer loses 20,000 yen at the normal payout rate, and the fifth person operates the rogue ROM and wins 10,000 yen. Shows. If there is a player H who is always playing on the same gaming machine and is always winning, it is possible that some kind of fraud is being performed. In this case, it is possible that regular customers who frequently come to the store are familiar with the actual situation of the store and are playing games in an advantageous manner, but the situation is that customers with a small number of store visits intensively play on the same game table to win. It is considered that some kind of fraud is being performed on the gaming table, and it can be presumed that the player H who always wins on such a gaming table is a fraudulent person. The present invention aims to find an illegal gaming table by focusing on such a situation. Hereinafter, a detailed description will be given with reference to each drawing.

FIG. 5 is a flow chart showing a first embodiment of a method for discriminating a game table to which an illegal apparatus according to the present invention is attached. Note that this flow is the same as the operation of the discrimination system 1 according to the first embodiment. First, the discrimination system 1 photographs the face of the player H playing on the gaming tables _{3-1 to} 3- _n with the corresponding cameras _4-1 to 4- _n (step S1). The start of the shooting, and when the player H has the operation of a seated game machine 3 _-1 to 3 _-n, also whether imaging subject started every 1 minute or the like is present To check. Images captured by the cameras _4-1 to 4- _n are taken into the image processing unit 21 and converted into digital image data. At the same time, the image processing unit 21 automatically performs various processes such as noise removal, gradation correction, color correction, and image compression as necessary. Thus the image processing unit 21 payout in gaming table 3 _-1 to 3 _-n of the machine number and the amusement machine 3 _-1 to 3 _-n image data of the generated player H is where the player is the game by It is automatically stored in the player database 20 in association with the rate W (step S2).

Next, the discrimination system 1 calculates the payout rate W, which is the ratio of the number of payouts to the number of hits at the gaming tables _{3-1 to} 3- _n played by the respective players H, based on the player database 20. The total number of players H whose ball rate W is equal to or higher than a predetermined rate is calculated for each of the gaming machines _{3-1 to} 3- _n , and the number of players H whose ball output rate is equal to or higher than the predetermined rate W is calculated. The average per game table is calculated (step S3). For example, it is possible to calculate the number of players H who have not lost the game table _{3-1 to} 3- _n by setting the player with a payout rate W of 100% or more. Calculates the average number of players per game machine _{3-1 to} 3- _n .

Next, the discrimination system 1 operates the player extraction means 25, selects the same player H from the face image data of each player H stored in the player database 20 by the face authentication means 23, and the player H concerned. A player who has calculated the number of games P so far in the store of H based on the player database 20, the number of games P is less than a predetermined number, and the payout rate W is not less than a predetermined ratio. H is extracted from the player database 20 (step S4). Then, when there is a player H who has "the number of games P <predetermined value" and "the payout rate W> predetermined value" (step S4: Yes), the corresponding player H is set as the player. It is extracted from the database 20. The number of games P can be set to an appropriate number of times for distinguishing between regular customers and other customers, for example, 3, 4, 5 or 10 times. Further, by setting the payout rate W to 100% or more, it is possible to extract at least the player H who has not lost. In addition, by setting “ball payout rate W>105%” or the like, the player H who is making a profit can be extracted. In the case of "step S4: No", when "the number of games P> predetermined value" is determined (step S3: No), it is determined that the player H is a regular customer, and then a predetermined time has passed. Then, the process of step S3 is executed again.

Next, the discrimination system 1 operates the fraudulent gaming table extracting means 26, and a certain gaming table _{3-1 to} 3- _n causes the player H (the number of games P is a predetermined number of times) extracted by the player extracting means 25. It is determined whether or not the number of players R played by the player H) whose payout rate W is equal to or higher than a predetermined rate is less than at least the average number Q calculated by the average number calculation means 24. Yes (step S5). Then, in the case of "the number of game players R>the average number of players Q" (step S5: Yes), the game machines _{3-1 to} 3- _n are regarded as the unauthorized game machines F having a high possibility that an unauthorized device is attached. Judge and extract. Then, if a warning by including the game machine 3 _-1 to 3 _-n on the display 5 is popped up by the warning means 27 to display to notify that it is illegal gaming table F, employees who looked at this display It is possible to quickly take a predetermined action on the illegal gaming table F. In addition, when it determines with "step S5: No", it determines with it not being the fraudulent gaming machine F, and complete|finishes a process. In this case, nothing is displayed on the display 5.

[Effects of First Embodiment]
According to the discrimination system and the discrimination method of the game table to which the illegal device is attached according to the first embodiment, the game table to which the illegal device such as the back ROM is attached is extracted as the illegal game table from all the game tables. By doing so, it is possible to efficiently find the illegal gaming machine. As a result, there is no need to inspect all gaming machines in order to find an illegal gaming table, which has the effect of reducing the labor required for work. And, there is an effect that it is possible to quickly respond to the illegal gaming table F.

2. Second Embodiment Next, a second embodiment of the system for discriminating a game table to which the unauthorized device according to the present invention is attached will be described. Although the above-mentioned first embodiment discriminates the illegal game table, the discrimination system 8 of the game table to which the illegal machine of the second embodiment is attached (hereinafter, simply referred to as “discrimination system 8”). Is to further discriminate the illegal player G. As a result, in addition to being able to efficiently detect the illegal game table to which the illegal device is attached, the illegal player G can also be efficiently detected, and the illegal game player G can be efficiently detected by the employee of the store. It becomes possible to warn.

[Configuration of discrimination system 8]
FIG. 6 is a block diagram showing a second embodiment of the discrimination system of the game table to which the unauthorized device according to the present invention is attached. The discrimination system 8 is the same as the discrimination system 1 of the first embodiment. The cameras _4-1 to 4- _n for photographing the faces of the respective players H playing on the game tables _{3-1 to} 3- _n , and the image processing. It is provided with a section 21, a player database 20, a face authentication means 23, an average number of people calculation means 24, a player extraction means 25, and an illegal game table extraction means 26. Since these are almost the same as those described in the first embodiment, detailed description will be omitted.
