Description

  The present invention relates to a game hall system, a game hall device, and a suspicious person detection method, and in particular, when a player whose face image is captured by an imaging means is an unregistered player or an unrecognized player. A game hall system, a game hall device, and a suspicious person detection method capable of determining whether or not an abnormal situation relating to a game has occurred due to the behavior of a player or an unrecognized player, and detecting a suspicious person About.

In a game arcade where game machines such as pachinko machines and slot machines are installed, there are players who perform an illegal act called a goto action for acquiring a game in an illegal manner with respect to the game machine.
For cheating, for example, using a so-called sensation device to illegally trigger a big hit, replace the regular ROM mounted on the board with a modified ROM, and increase the probability of jackpot, There are various things such as a medal payout function or a throw-in function malfunctioning by inserting a special instrument such as a deformed celluloid, piano wire or wire from a medal payout opening or medal insertion opening of the machine.

In order to detect such an illegal act, generally, a surveillance camera for monitoring a player is attached in a game arcade.
In addition, as a technique for discovering fraudulent activity with a surveillance camera, for example, a player who captures an image of a player's face with a surveillance camera and performs cheating based on the face image obtained by the imaging (hereinafter referred to as a suspicious person) A technique for detecting the above is disclosed.
For example, in Patent Document 1, it is determined whether or not a player's face image captured by a surveillance camera provided in a game hall has already been registered in the game hall. A technique is disclosed in which, when an image cannot be recognized as a face, a notification for prompting confirmation of the player is given to an employee of the game hall.
Further, in Patent Document 2, in addition to face authentication processing using a face image, a player's motion is captured by a monitoring camera, and the captured player's motion image corresponds to an abnormal motion registered in advance in the game hall. A technique for determining whether or not to perform an alarm that indicates an abnormality in the case of an abnormal operation is disclosed.

However, in the technique described in Patent Document 1, a player whose face image is captured by a surveillance camera is a player whose face image is not registered in the game hall (hereinafter referred to as an unregistered player), a mask, When it is determined that the player is not recognized as a face by wearing sunglasses or the like (hereinafter referred to as a non-recognized player), the employee is informed. In other words, in this technology, only whether or not the notification condition corresponds to an unregistered player or a non-recognized player, and whether or not an illegal act has been performed by the act of these players, or an illegal act is performed. I did not judge whether it was possible.
Therefore, for example, even when a player who first visits a game hall plays a game correctly without performing an illegal act, the player is determined as an unregistered player and is notified to the employee.
In the amusement hall, most players play games correctly without cheating, and cheating is not frequent. Nevertheless, in this technology, regardless of whether or not fraudulent activity has been performed, since it is notified only by determining that it is an unregistered player or unrecognized player, the ratio of the number of fraud detections to the number of notifications is Lower. As a result, this technology has increased false alarms and has low reliability.

On the other hand, in the technique described in Patent Document 2, the employee is notified when it is determined that the action of the player imaged by the monitoring camera is an abnormal action that is regarded as an illegal action. Compared to this technology, it is a highly reliable technology.
However, in this technology, face authentication processing is performed based on the player's face image, which distinguishes it from the employee, and the player at the time when the membership card is inserted or cash is inserted. It authenticates whether or not they are the same person, and does not identify the above-mentioned unregistered player or unrecognized player.
For this reason, this technology cannot detect unregistered players or unrecognized players who are likely to perform fraud.

In addition, as a mode of cheating, multiple people sit next to each other on adjacent gaming machines (hereinafter referred to as consecutive seats), one person cheating, and the other being a watchman or cheating In some cases, the roles are divided.
However, with the techniques described in Patent Document 1 and Patent Document 2, it is not possible to detect in advance a fraudulent act that is performed by attending multiple persons.

  The present invention has been proposed in order to solve the above-described problems and the like. When the player whose face image is captured by the surveillance camera is an unregistered player or an unrecognized player, this A game hall system, a game hall device, and a suspicious person capable of detecting a suspicious person by judging whether or not an abnormal situation related to a game has occurred due to an act of a registered player or an unrecognized player The purpose is to provide a detection method.

  In order to achieve the above object, a game hall system according to the present invention images a face of a player located in front of a gaming machine in a gaming hall system provided in a gaming hall where a plurality of gaming machines are installed. Face imaging means for obtaining the player's face image, face image storage means for storing the face image obtained by the face imaging means, and information relating to the player are registered together with information relating to the player's face image The player information storage means stored as player information and the information related to the face image stored in the registered player information match or approximate information related to the face image obtained by the face imaging means. Registration judging means for judging whether or not there is a face, or face authentication means for judging whether or not there is a predetermined number or more of facial feature information in the face image obtained by the face imaging means And the registration judgment means The player corresponding to the face image when it is determined that the registered player information does not have information about the face image that matches or approximates the information about the face image obtained by the image pickup means as an unregistered player. When the face authentication means determines that the number of facial features in the face image obtained by the face image pickup means is less than a predetermined number, the player corresponding to the face image is not recognized. And an abnormality occurrence judging means for judging whether or not an abnormal situation related to a game has occurred due to an action of an unregistered player or an unrecognized player.

  In addition, the game room apparatus of the present invention stores a face image acquired from a face imaging unit that captures a face of a player located in front of the gaming machine and obtains the face image of the player. Among the image storage means, the player information storage means for storing information about the player together with information about the player's face image as registered player information, and information about the face image stored in the registered player information, Registration judgment means for judging whether or not there is information that matches or approximates information related to the face image obtained by the face image pickup means, or among the face images obtained by the face image pickup means.

[Amusement hall system]
First, the configurations of the game hall system and the game hall apparatus of the present embodiment will be described with reference to FIGS.

As shown in FIG. 1, the game hall system 1 according to the present embodiment includes a plurality of gaming machines 10, an intermediary machine 20, a call lamp 30, a stand computer 40, an island computer 50, a hall computer 60, an image processing device 70, a network. A video recorder (hereinafter referred to as NVR) 80 and a monitor 90 are included. Each of these apparatuses includes a communication unit and is connected to be able to perform data communication via a predetermined network (for example, a local area network).
The game hall system 1 configured as described above includes a face lamp 33 that captures a face camera 33 that captures a player positioned in front of the gaming machine 10, and a face image captured by the face camera 33 is displayed. If it is not registered in the image processing device 70 or cannot be recognized as a face, an abnormal situation related to the game due to the action of the player (unregistered player or unrecognized player) corresponding to the face image It is determined whether or not an error has occurred. And when an abnormal situation related to the game occurs, it is considered that this unregistered player or unrecognized player may or may have been cheating, and given notification, It functions as a suspicious person detection system that detects a suspicious person.
Hereinafter, the configuration of each device of the game hall system 1 will be described in detail.

The gaming machine 10 is a variety of gaming machines that use a gaming medium such as a game ball or a medal, such as a pachinko machine or a slot machine.
The inter-machine 20 is a gaming medium lending device that is provided for each gaming machine 10 and lends a predetermined number of gaming media according to the amount of money to the gaming machine 10 by inserting cash or the like.

As shown in FIG. 2, various gaming signals are output from the gaming machine 10 and the inter-vehicle machine 20.
The gaming signal output from the gaming machine 10 includes an out signal that indicates the number of gaming media inserted into the gaming machine 10, a safe signal that indicates the number of gaming media paid out from the gaming machine 10, and a jackpot that indicates the jackpot state of the gaming machine 10 Signal, a start signal output for each game, and the like.
In addition, the game signal output from the inter-machine 20 includes a sales signal indicating the number of game media lent.
These signals are input to the calling lamp 30 and transmitted to the hall computer 60 via a relay information processing apparatus such as the stand computer 40 and the island computer 50. The hall computer 60 totals game data for each gaming machine 10. To manage.

The calling lamp 30 is installed above the gaming machine 10 and functions as a notification unit by lighting or blinking a lamp 36 such as a light bulb or LED.
Specifically, as shown in FIG. 3, the call lamp 30 includes a communication unit 31 that performs communication processing with each device, a storage unit 32 that stores programs for executing various functions of the call lamp 30, and the like. A face camera 33 for picking up the face of the player, an operation camera 34 for picking up the action of the player, a control unit 35 configured by a CPU and controlling various functions of the call lamp 30. And the control part 35 controls these parts, and the ringing lamp 30 operate | moves as follows.

The calling lamp 30 receives a game signal transmitted from the gaming machine 10 and a sales signal transmitted from the inter-story machine 20 via the communication unit 31, and transmits these various signals to the computer 40.
The face camera 33 and the operation camera 34 are imaging means capable of capturing moving images and still images, such as a CCD camera and a digital video camera, and image a specific area for each gaming machine 10 as an imaging range.
As shown in FIG. 4, the face camera 33 is a face image pickup unit that picks up the face of the player located in front of the gaming machine 10 and obtains a face image of the player. The operation camera 34 is an operation imaging unit that captures an image of an operation area of a player located in front of the gaming machine 10, particularly a portion where an illegal act is easily performed (for example, near the player's hand). An action image is obtained.

The call lamp 30 stores the game table number corresponding to the call lamp 30, the current imaging mode of the face camera 33 and the operation camera 34, and the like in the storage unit 32.
The imaging mode is a mode for setting the frame rate and the number of pixels of the face camera 33 and the operation camera 34 according to the presence or absence of a player.
Further, the calling lamp 30 stores the captured image (face image, motion image) captured by the face camera 33 and the operation camera 34, the type of captured image, the imaging time, and the transmission sequence number in the storage unit 32.
The “transmission serial number” is numbered as a unit from the time the player is seated until the player leaves the seat. As a method for determining whether a player is seated or left, for example, when a seating sensor (not shown) detects that a player is seated in a gaming chair provided in front of the gaming machine 10, an out signal is output. When it is detected, when a sales signal is detected, etc., it is judged as seated, when it is no longer detected by the seating sensor, when the out signal is not detected for a predetermined time, or when the membership card is discharged, etc. Can do.

  The calling lamp 30 transmits the gaming machine number, the type of the captured image, the imaging time, and the transmission sequence number to the image processing device 70 and the NVR 80 together with the captured image stored in the storage unit 32 via the communication unit 31. At this time, the captured image is compressed into a predetermined format (for example, JPEG, MPEG4, etc.), and the compressed data is transmitted.

The calling lamp 30 can set the imaging mode of the face camera 33 and the operation camera 34. The face camera 33 and the operation camera 34 have, for example, a normal mode and an eco mode as imaging modes. Yes.
The normal mode is an imaging mode that is selected when there is a player in the gaming machine 10, and for example, imaging is performed at a frame rate of about 30 fps and a pixel count of about 1280 × 960 pixels.
On the other hand, the eco mode is an imaging mode that is selected in the gaming machine 10 when there is no player. For example, the eco mode is captured at a frame rate of about 5 fps and the number of pixels is about 320 × 240 pixels. Imaging is performed with a reduced processing capability.
For example, when the player leaves the seat, the mode is switched from the normal mode to the eco mode. By capturing an image in the eco mode, the face camera 33 and the operation camera 34 are compared with those in the normal mode. Storage capacity can be reduced, and long-time imaging can be achieved. Further, since a high imaging processing capability is not required, the small face camera 33 and the operation camera 34 can be used, so that they can be installed in the calling lamp 30 or the stand computer 40.

  In this embodiment, it is assumed that the face camera 33 and the operation camera 34 are individually installed. However, the present invention is not limited to this, and the face camera 33 and the operation camera 34 are configured by one camera. Both functions may be provided. Further, in the present embodiment, one face lamp 33 and one operation camera 34 are provided on one call lamp 30, but two or more of the face camera 33 and the operation camera 34 are provided. You can also.

The stand computer 40 and the island computer 50 are information relay processing devices provided for each gaming machine 10 or each gaming machine island to which a plurality of gaming machines 10 are attached, and are exchanged between the gaming machine 10 and the hall computer 60. Relay information.
The stand computer 40 transmits various signals (game signal and sales signal) received via the calling lamp 30 to the island computer 50. The island computer 50 receives various signals transmitted from the platform computer 40 and transmits them to the hall computer 60.

The hall computer 60 is an information processing apparatus that collects and manages game data for each gaming machine 10 based on game signals transmitted via the island computer 50.
Specifically, as shown in FIG. 5, the hall computer 60 stores a communication unit 61 that performs communication processing with each device, a program for executing various functions of the hall computer 60, and stores game data and the like. A storage unit 62 that stores data, and a control unit 63 that is configured by a CPU and controls various functions of the hall computer 60 are provided. The control unit 63 controls these units so that the hall computer 60 is configured as follows. Operate.

The hall computer 60 stores the game data totaled for each gaming machine 10 in the storage unit 62 as a game history database based on the game signal received from the island computer 50 via the communication unit 61. In addition, game data is transmitted to the image processing apparatus 70 at a predetermined cycle via the communication unit 61.
In addition, when an abnormal operating situation occurs in the gaming machine 10, the hall computer 60 transmits a gaming machine number, a gaming time, and the like regarding the gaming machine 10 to the image processing apparatus 70 and the NVR 80 together with an operating abnormality signal.

As shown in FIG. 6, the game history database includes game data (game date / time, number of outs (number of inputs), number of safes (number of payouts), number of starts (number of games), amount of money to be added, , The number of jackpots (number of special prizes), the face ID, the identification name of the face image, the identification name of the motion image, and the like are stored in association with each other.
The “face ID” is identification information that is assigned to each player based on the player's face image captured by the face camera 33 and can uniquely identify the player.
The “face image identification name” and the “motion image identification name” are identification names (file names) uniquely assigned to the player's face image and the player's action image stored in the NVR 80. is there.
The “face ID”, “face image identification name”, and “motion image identification name” are received from the image processing apparatus 70 via the communication unit 61 and acquired.

The hall computer 60 operates as an operation status determination unit, thereby monitoring the operation status of each gaming machine 10 and determining whether or not an abnormal operation status has occurred. If it is determined that an abnormal operating situation has occurred in the gaming machine 10, the gaming machine number of the gaming machine 10, the gaming time, etc., along with the operating abnormality signal indicating the operating abnormality via the communication unit 61, The image is transmitted to the image processing device 70 and the NVR 80.
Here, the abnormal operation situation is a situation that can occur when an illegal act is performed. For example, when the number of jackpots generated within a small amount of input is a predetermined number or more, or a small number of start times The number of jackpots that occurred in the above is a predetermined number of times or more.

The NVR 80 is a recording device for recording a captured image (face image, operation image) received from the calling lamp 30.
Specifically, the NVR 80 operates as a face image storage unit, thereby storing a face image obtained by the face camera 33 and also operating as an operation image storage unit so that the operation camera 34 is operated. An action image of the player obtained by imaging is stored.
Methods for storing these images include time-lapse recording and continuous recording. Time-lapse recording is a method of storing captured images received from the calling lamp 30 at regular intervals. Continuous recording is a method of storing the captured image as a continuous moving image. In a normal state, the control unit of the NVR 80 stores captured images by time-lapse recording, and switches from time-lapse recording to continuous recording when an abnormal signal indicating an abnormal signal related to a game is received from the image processing device 70. Thereby, the player of the gaming machine 10 determined to be abnormal can be recorded as a continuous moving image.

Further, the NVR 80 stores a captured image captured between the player's seating and leaving the seat as one unit. Specifically, based on the “game table number”, “type of captured image”, and “transmission sequence number” received together with the captured image from the calling lamp 30, the transmission sequence is classified for each type of captured image by type of captured image. Remember every turn. Then, an identification name (for example, “123KA01”, “123DO01”) is assigned to each unit to uniquely identify each image to be stored.
Furthermore, mark information indicating that an abnormal situation related to a game has occurred is recorded in the captured image stored for each unit. For example, when an abnormal signal indicating an abnormal situation related to a game is received from the image processing device 70, mark information is recorded for a captured image determined to be abnormal.
In this way, the gaming machine 10 in which the mark information is recorded can be identified as the gaming machine 10 that is the target of fraud.

The monitor 90 is composed of a liquid crystal display or the like, and includes captured images (face images, motion images) stored in the NVR 80, and various information managed by the hall computer 60 (operating status of each gaming machine 10, sales management information). Etc.) is displayed.
For example, when a predetermined search condition (game date / time, model name, game machine number, etc.) is input by an employee of a game hall from an input means (not shown) of the hall computer 60, it is stored in the NVR 80 corresponding to this condition. The displayed face image and action image are displayed.
In addition, the layout of the gaming island 100 and the gaming machines 10 installed in the amusement hall is displayed, and the gaming machines 10 that are operating, the gaming machines that are not operating, the gaming machines 10 that are hitting big hits, etc. are displayed on the layout. To do.

Furthermore, the monitor 90 functions as an informing means for informing an employee of the game hall by displaying the gaming machine 10 in which an abnormal situation relating to the game has occurred.
Specifically, the gaming machine 10 that has been determined to be an abnormal situation related to a game by an image processing apparatus 70 (abnormality generation determination unit) described later is indicated by a different color, mark, or the like on the layout layout. Furthermore, a different display is performed according to the notification level (notification by caution, notification by warning) (see FIG. 11). In this way, the employee can alert the player according to the notification level, and can prevent illegal acts against the gaming machine 10 in advance.

[Image processing device]
The image processing device 70 operates as an example of a game field device according to the present invention, and determines whether or not the player whose face image is captured by the facial camera 33 is an unregistered player or an unrecognized player. And whether or not an abnormal situation related to the game has occurred due to the action of the unregistered player or unrecognized player when it is determined that the player is an unregistered player or unrecognized player It is an information processing apparatus provided with a function for executing a predetermined notification process when it is determined that an abnormal situation related to a game has occurred.

  In order to realize each of such functions, the image processing apparatus 70 includes a communication unit 71 and an image processing apparatus 70 that transmit and receive game data and captured images to and from the calling lamp 30 and the NVR 80, as shown in FIG. A storage unit 72 that stores programs for executing various functions provided, a control unit 73 configured by a CPU and controlling various functions provided in the image processing apparatus 70, and the like are provided. The control unit 73 controls these units. As a result, the image processing apparatus 70 operates as follows.

The image processing device 70 transmits / receives predetermined information to / from the calling lamp 30 via the communication unit 71.
Specifically, in addition to receiving the captured image (face image, motion image) from the call lamp 30, a notification control signal for executing notification processing is transmitted to the call lamp 30.
Further, the image processing apparatus 70 transmits and receives predetermined information to and from the hall computer 60 via the communication unit 71.
Specifically, the game data is received from the hall computer 60 at a predetermined cycle, and a notification control signal for executing notification processing is transmitted to the hall computer 60. The game data can be received not only from the hall computer 60 but also via the island computer 50.
Further, when an abnormal operating situation occurs in the gaming machine 10, the image processing device 70 receives a gaming machine number, a gaming time, and the like regarding the gaming machine 10 together with an operating abnormality signal from the hall computer 60.

In the image processing device 70, the storage unit 72 operates as a face image storage unit, thereby temporarily storing the face image received from the calling lamp 30. Also, by operating as an operation image storage means, the operation image of the player received from the calling lamp 30 is temporarily stored.
These images stored in the storage unit 72 are used in face authentication and operation analysis processing to be described later. For this reason, it is deleted from the storage unit 72 after the face authentication and the operation analysis.

In the image processing device 70, the storage unit 72 operates as player information storage means, so that information about the player (game data) is registered along with information about the player's face image (face ID, etc.). Store as a database.
Specifically, as shown in FIG. 8, the registered player database includes a face ID, game data (game date / time, model, game machine number, input amount, number of balls, etc.) relating to the ball and the face image. The identification name, the identification name of the motion image, and the unregistered player flag are stored in association with each other.
The “face ID” is assigned to each player based on the player's face image captured by the face camera 33. Specifically, information related to facial features (hereinafter referred to as a feature portion) acquired from a facial image by an image processing device 70 (face authentication means) described later is stored in a storage unit 73 (face feature point database) of the image processing device 70. A new face ID or an existing face ID is given depending on whether or not it matches or approximates the feature part registered in the.
The “face image identification name” and “motion image identification name” are the “game table number”, “type of captured image”, and “transmission sequence number” received by the image processing apparatus 70 from the call lamp 30 together with the captured image. Based on the above, for each game machine number, an identification name is assigned for each transmission serial number for each type of captured image, and the same identification name as that assigned in the NVR 80 described above is assigned. ing.
The “unregistered player flag” is identification information for identifying that the player's face ID is not registered in the game hall and that the player is a new player. When a new player (unregistered player) is registered in the registered player database, predetermined information is stored in the unregistered player flag.

In addition, the image processing apparatus 70 stores the face ID registered in the registered player database and the feature portion corresponding to the face ID as a face feature point database in the storage unit 72.
The characteristic portion is stored by being acquired from the face image by an image processing device 70 (face authentication means) described later.
The face feature point database may be included in the registered player database, so that the face feature point database and the registered player database may be combined into one database. In this case, the face ID is associated as a key.

Thus, the image processing device 70 can manage the game data of the player for each face ID according to the game history. That is, the face ID can be used in place of the member ID given by registering as a member in the game hall.
Usually, a player who performs a fraudulent act often performs a fraudulent act by playing as a general player without registering as a member at a game hall where he / she visits for the first time. In such a case, the game data of the general player The game data of the player who performs the fraudulent action is included in the list, and it is difficult to identify the suspicious person.
However, even if the membership is not registered in the game hall as in this embodiment, a new face ID is assigned and registered in the registered player database as an unregistered player. Can do.

In the image processing device 70, the storage unit 72 operates as a non-recognized player storage unit, so that the game data of the player identified as a non-recognized player from the face image obtained by the face camera 33 is captured. Are stored as a non-recognized player database.
Specifically, as shown in FIG. 9, the non-recognized player database includes a game data (game date / time, model, game machine number, input amount, output ball) in a non-recognized number assigned to each non-recognized player. Number), the identification name of the face image that captured the player, and the identification name of the action image are stored in association with each other.

In the image processing device 70, the storage unit 72 operates as a suspicious operation image storage unit, thereby storing a suspicious operation image indicating a suspicious operation among operations performed by the player as a suspicious operation database.
The suspicious motion image is an image that matches or is similar to a so-called goto action, for example, an operation in which a hand is placed in the vicinity of a slot machine medal payout exit or medal insertion slot for a long time, a winning slot on the front of a pachinko machine An image such as an action of placing a hand in the vicinity for a long time is stored.

In the image processing apparatus 70, whether or not the face feature obtained by the face camera 33 includes a predetermined number of feature parts of the player's face in the face image obtained by the control unit 73 operating as face authentication means. By determining whether or not, the player's face authentication is performed.
As a face authentication method, a known face authentication technique can be used. For example, the following method can be used.
The image processing device 70 detects a face area representing the player's face from the face image received from the calling lamp 30, and in this area, the eyes, nose, mouth, etc. , Feature points corresponding to the nasal head, mouth corner, upper lip, lower lip, and the like are extracted. Further, the length, angle, etc. of the line segment connecting the extracted feature points are acquired as the feature portion of the player's face.
Then, it is determined whether or not the acquired feature portion is equal to or greater than the number (predetermined number) of feature portions necessary for recognition as a face. On the other hand, when it is determined that the number of feature points is equal to or less than the predetermined number, the player corresponding to the face image is specified as a non-recognized player.

In the image processing apparatus 70, the control unit 73 operates as a registration determination unit, so that there is a registered player database that matches or approximates information related to the face image obtained by the face camera 33. Determine whether or not.
Specifically, the image processing apparatus 70 searches for a feature portion acquired by the face authentication unit described above that matches or approximates the face feature point database, and there is a feature portion that matches or approximates. Acquires a face ID corresponding to this feature portion.
Then, the image processing apparatus 70 determines whether or not the acquired face ID is stored in the registered player database. If the acquired face ID is not stored in the registered player database, the player corresponding to the face image is specified as an unregistered player, and a new face ID is assigned, and based on this face ID Store them in the face feature point database and the registered player database.

In the image processing apparatus 70, whether or not the suspicious operation database matches or approximates the operation image obtained by the operation camera 34 by the control unit 73 operating as the suspicious operation determination unit. Determine whether.
Specifically, the image processing apparatus 70 performs an operation analysis from the operation image received from the calling lamp 30, and the player's operation obtained by the analysis is identical or approximate to the suspicious operation image in the suspicious operation database. Judge whether there is.
As a method for motion analysis and motion image coincidence determination, a method used in a known motion analysis technique can be used.

In the image processing apparatus 70, the control unit 73 operates as a target gaming machine determination unit, so that the gaming machine 10 corresponding to the facial camera 33 that captures an unregistered player or an unrecognized player is used as a target gaming machine. Identify.
Further, in the image processing device 70, the control unit 73 operates as the adjacency determination unit, so that the target gaming machine specified by the target gaming machine determination unit is based on the arrangement of the gaming machines 10 in the game hall. It is determined whether or not two or more are adjacent at approximately the same time.
That is, it is determined whether or not a player (an unregistered player or an unrecognized player) who is likely to perform an illegal act is attending.

The image processing device 70 operates when the control unit 73 operates as an abnormality occurrence determination unit so that the player whose face image is captured by the facial camera 33 is an unregistered player or an unrecognized player. It is determined whether or not an abnormal situation related to a game has occurred due to the action of an unregistered player or an unrecognized player.
Here, the abnormal situation related to the game is “when attending at almost the same time (seating abnormality)”, “when suspicious gaming action (gaming action abnormality)”, “operating situation where the gaming machine is abnormal "If (operation status abnormality)".

Further, when the image processing apparatus 70 determines that an abnormal situation related to a game has occurred due to an action of an unregistered player or an unrecognized player, the image processing device 70 displays the screen of the monitor 90 or an employee of the game hall. Is instructed to perform predetermined notification processing (notification control means) to the notification means such as the income and the calling lamp 30 (lamp 36).
This notification process is performed in stages, such as notification by “caution” → notification by “warning”.
Next, a specific example when the image processing apparatus 70 (abnormality occurrence determination means) determines that an abnormal situation related to a game has occurred due to an action of an unregistered player or an unrecognized player will be described.

FIG. 10 is a chart showing each pattern when it is determined that an abnormal situation related to a game has occurred due to an action of an unregistered player or an unrecognized player.
<Pattern 1: [Unregistered player or non-recognized player + abnormal seating abnormality]>
The image processing apparatus 70 determines that the player whose face image is captured by the facial camera 33 is an unregistered player or an unrecognized player, and images the unregistered player or unrecognized player. If it is determined that two or more gaming machines 10 (target gaming machines) corresponding to the facial camera 33 are adjacent to each other at approximately the same time based on the arrangement of the gaming machines 10 in the game hall, an abnormality related to the game It is determined that an unusual situation has occurred.
This means that if there are multiple players (unregistered players or non-recognized players) who are likely to commit fraudulent activities, they may be fraudulently performed at the same time. Thus, it is determined that an abnormal situation related to the game has occurred.
Here, as shown in FIG. 11, “two or more adjacent” states target gaming machines 10 adjacent to each other in Katashima 100a and 100b among gaming machines 10 arranged on the gaming island 100. . Then, in Katashima 100a and 100b, when an unregistered player and an unregistered player attend, a non-recognized player and an unrecognized player attend, and an unregistered player and an unrecognized player join together. We are monitoring when to sit.

As a notification mode in this case, notification by “caution” is performed.
In the case of performing notification on the monitor 90, as shown in FIG. 11, the gaming machine 10 in which an abnormality has occurred is displayed on the layout layout in the game hall in a recognizable manner.
For example, while changing the background color and mark of the gaming machine 10 (131th to 133rd) in which an abnormality has occurred, a notification message is displayed to alert the employee. Further, along with such a screen display, a corresponding face image or motion image may be displayed.
In addition, it is also possible to notify the income. The image processing device 70 is communicably connected to the intercom, and transmits a notification control signal to the intercom to execute the notification. In this case, for example, a message that calls attention is sent, such as “Now, there are abnormalities in the 131st to 133rd series. Please check.”
As described above, since the gaming machine 10 in which an abnormality has occurred is recognizable notification on the screen of the monitor 90 or on the intercom, the employee of the gaming hall can be a player (unregistered) of the gaming machine 10 in which the abnormality has occurred. A player or a non-recognized player) can be detected to detect a suspicious person who tries to perform a fraudulent act together. As a result, fraudulent acts due to consecutive seats can be prevented in advance.

<Pattern 2: [Unregistered player or unrecognized player + gaming operation abnormality]>
The image processing apparatus 70 determines that the player whose face image is captured by the facial camera 33 is an unregistered player or an unrecognized player, and images the unregistered player or unrecognized player. When it is determined that the player's motion image captured by the motion camera 34 matches or approximates the suspicious motion image, it is determined that an abnormal situation related to the game has occurred.
This means that if a player who has a high probability of cheating (unregistered player or unrecognized player) is performing suspicious behavior, he / she will attempt cheating. It is determined that an abnormal situation related to the game has occurred.
As a notification mode in this case, notification by “caution” is performed as in the case of pattern 1.
Thereby, it is possible to detect a suspicious person who intends to perform a so-called goto action, and to prevent an illegal action.

<Pattern 3: [Unregistered player or unrecognized player + operating status abnormality]>
The image processing apparatus 70 determines that the player is an unregistered player or an unrecognized player from the face image of the player imaged by the facial camera 33, and uses the image of the unregistered player or the unrecognized player. When the gaming machine 10 (target gaming machine) corresponding to the camera 33 determines that the gaming machine 10 (the target gaming machine) is in an abnormal operating state at the time when the image was taken, it is determined that an abnormal situation related to the game has occurred.
Specifically, the image processing apparatus 70 makes a determination by receiving an operation abnormality signal indicating an operation abnormality of the gaming machine 10 from the hall computer 60 together with the gaming machine number and gaming time of the gaming machine 10.
This is because the gaming machine 10 played by a player (unregistered player or unrecognized player) who has a high possibility of performing an illegal act has a continuous operation situation advantageous to the player that does not occur in a normal game. If it occurs, it is determined that an abnormal situation related to the game has occurred by regarding that the illegal act has been performed.
The “abnormal operating status” of the gaming machine 10 is, for example, when the number of jackpots that occurred within a small amount of money is greater than or equal to a predetermined number, or when the number of jackpots that occurred within a small number of starts is greater than or equal to a predetermined number Etc.
As a result, since it can be detected when an illegal act is performed, it is possible to detect a suspicious person before damage increases.

  In the above patterns 1 to 3, when it is determined that an abnormal situation relating to a game has occurred, an action by a non-malicious player may be included, so that the warning is used as an alert. By adding this condition, the reliability of the abnormality determination is improved, and when this condition is satisfied, notification by “warning” is performed. Specifically, there are the following patterns.

<Pattern 4: [Pattern 1 + Operation status abnormality]>
If the image processing apparatus 70 determines that the gaming machine 10 is abnormal in the operation status according to the condition of the pattern 1, the image processing apparatus 70 determines that there is a high possibility that an illegal act has been performed, and notifies the notification means. Instructs execution of notification by “warning”.
<Pattern 5: [Pattern 1 + gaming operation abnormality]>
If the image processing apparatus 70 further determines that the gaming operation abnormality is in accordance with the condition of the pattern 1, it determines that the illegal action is likely to be performed, and performs notification by “warning” to the notification means. Instruct.
<Pattern 6: [Pattern 2 + Abnormal operation status]>
When the image processing apparatus 70 determines that the gaming machine 10 is in an abnormal operating condition according to the condition of the pattern 2, the image processing apparatus 70 determines that there is a high possibility that an illegal act has been performed, and notifies the notification means. An instruction to execute a predetermined notification process is given.

In the notification by such a warning, for example, in the case of performing the notification by the monitor 90, by displaying in a display mode different from the notification by caution, the employee of the game hall can easily identify the degree of notification (FIG. 11).
On the other hand, in the case of reporting to the income, for example, a warning message such as “There is a possibility of a suspicious person in the 231st series. Please check immediately” is sent.
Further, the notification may be performed by lighting a warning by the lamp 36 of the calling lamp 30 or outputting a warning sound from a speaker. Furthermore, the operation of each device such as the corresponding gaming machine 10 or the inter-vehicle machine 20 may be restricted.
Next, a suspicious person detection method among the operations performed by the game hall system according to the present embodiment configured as described above will be described with reference to FIGS. 12 and 13.

[Suspicious person detection method]
FIG. 12 is a flowchart showing an overall procedure of the suspicious person detection method according to the present embodiment.
FIG. 13 is a flowchart showing image identification processing of the suspicious person detection method according to the present embodiment.
In the following description, it is assumed that the face camera 33 and the operation camera 34 of the calling lamp 30 are always capturing images.

The hall computer 60 tabulates game data based on the game signals received from the island hall computer 50 (S10), and stores the tabulated game data in the game history database.
The hall computer 60 determines whether or not an abnormal operating situation has occurred in each gaming machine 10 (S11). When it is determined that an abnormal operating situation has occurred in the gaming machine 10 (S11: YES), the image processing device 70 displays the gaming machine number, gaming time, etc. of the gaming machine 10 together with the operating abnormality signal indicating the operating abnormality. To the NVR 80 (S12).
The image processing apparatus 70 and the NVR 80 receive the operation abnormality signal transmitted from the hall computer 60 (S13, S14) and store it.
Note that the processing of S12 is appropriately executed even in S15, S19, and S21 and later, which will be described later, when an abnormal operation situation occurs.

On the other hand, the call lamp 30 determines whether or not there is a player in front of the gaming machine 10 (S15). For example, when the seating sensor detects the player, it receives an out signal or a sales signal. In such a case, it is determined that there is a player in front of the gaming machine 10.
When it is determined that there is a player (S15: YES), the calling lamp 30 changes the imaging mode of the face camera 33 and the operation camera 34 from the eco mode to the normal mode (S16). 33 and the operation camera 34 image the player based on the image capturing mode (S17).
Next, the calling lamp 30 transmits the captured image (face image, motion image) captured in S17 to the image processing device 70 and the NVR 80 (S18). Specifically, for example, the face image is transmitted only once or a plurality of times when the presence of the player is recognized, and the motion image is transmitted at a constant interval (for example, once a minute). Note that these transmission timings can be changed as appropriate.
At this time, the calling lamp 30 also transmits the “game table number”, “image type”, and “transmission sequence number” together with the captured image.

The NVR 80 receives the captured image transmitted from the calling lamp 30 (S19).
The NVR 80 stores the received captured images at regular intervals (time-lapse recording), and captures between the seating and leaving of the player based on the gaming machine number and the transmission serial number received from the call lamp 30. The captured image is stored as one unit. Further, an identification name is assigned for each unit and stored (S20).
The image processing apparatus 70 receives the captured image transmitted from the calling lamp 30 (S21), and similarly to the NVR 80 of S20, the image processing apparatus 70 identifies the captured image based on the gaming machine number and transmission serial number received from the calling lamp 30. Is granted. Then, “image identification processing” is performed based on the received captured image (S22).

Next, the image identification process (S22) will be described with reference to FIG.
First, the image processing apparatus 70 (face authentication means) performs face authentication (S221).
Specifically, the image processing device 70 extracts feature points from the face image received from the calling lamp 30. And the length, angle, etc. of the line segment which connected between each feature point are acquired as a feature part of a player's face from the extracted several feature points. The acquired feature portion is stored in the face feature point database.
Next, it is determined whether or not the acquired feature portions are equal to or greater than the number (predetermined number) of feature portions necessary for recognition as a face (S222).
As a result of the determination, if it is determined that there are a predetermined number or more of characteristic portions (S222: YES), the face image is recognized as a face. On the other hand, when it is determined that the number of feature points is equal to or less than the predetermined number (S222: NO), the player corresponding to the face image is specified as “non-recognized player” (S223).

Next, the image processing device 70 (suspicious motion determination means) performs motion analysis using the motion image received from the calling lamp 30 (S224).
It is determined whether or not there is an action of the player obtained by the analysis that matches or approximates the suspicious action image in the suspicious action database (S225).
As a result of the determination, if it matches or approximates the suspicious motion image (S225: YES), it is specified that a gaming motion abnormality has occurred in the player corresponding to the motion image (S226).

Subsequently, in the process of S222 of the image identification process, it is determined whether or not the face image received from the calling lamp 30 has been recognized as a face (S23).
When the face image is not recognized as a face (S23: NO), that is, when it is specified as a non-recognized player, game data and the like related to the player are registered in the non-recognized player database (S24). ).
On the other hand, when the face image is recognized as a face (S23: YES), the image processing device 70 (registration determination means) matches or approximates information related to the face image in the registered player database. It is determined whether or not there is something (S25). Specifically, a face ID corresponding to the feature portion extracted in the image identification process (S221) is extracted from the face feature point database, and whether or not the extracted face ID is already stored in the registered player database. to decide.

As a result of the determination, if it is determined that the image processing apparatus 70 is not stored in the registered player database (S25: NO), the player corresponding to the face image is identified as “unregistered player”, A new face ID is issued (S26).
Then, the game data, the identification name of the face image, and the identification name of the motion image are associated with the new face ID and stored in the registered player database, and the registered player database is updated (S27). At this time, predetermined information indicating an unregistered player is stored in the unregistered player flag of the registered player database.

On the other hand, as a result of the determination in S25, if the image processing apparatus 70 determines that the image is stored in the registered player database (S25: YES), the game data and the identification name of the face image are added to the existing face ID. And the identification name of the motion image are associated with each other and stored in the registered player database, and the registered player database is updated (S27).
The image processing apparatus 70 transmits the face ID based on the face image, the identification name of the facial image, and the identification name of the motion image to the hall computer 60 (S28). The hall computer 60 receives the face ID and the like (S29), stores it in the game history database, and updates the registered player database (S30).

Next, the image processing apparatus 70 (abnormality occurrence determination means) determines whether or not an abnormal operating situation has occurred in the gaming machine 10 in which an unregistered player or an unrecognized player plays (S31).
If an abnormal operating situation has not occurred (S31: NO), it is determined that an abnormal situation regarding the game has not occurred, and the process is terminated.
On the other hand, if an abnormal operation situation has occurred (S31: YES), it is determined that an abnormal situation relating to the game has occurred, and the game table number, game date and time, etc. are displayed together with an abnormality signal indicating the abnormal situation relating to the game. (S32).
When the NVR 80 receives the abnormal signal transmitted from the image processing apparatus 70 (S33), the NVR 80 records the mark information on the captured image of the gaming machine 10 determined to be in an abnormal operating state, and records the storage method in the time-lapse recording. Is switched to continuous recording to perform recording processing (S34).
If the image processing apparatus 70 determines that an abnormal operating situation has occurred, the image processing apparatus 70 transmits a notification control signal for notification by caution to the hall computer 60 and the intercom (S35).
The hall computer 60 receives the notification control signal from the image processing device 70, and performs predetermined notification processing in the gaming machine 10 corresponding to the gaming machine number (S36). As a result, as shown in FIG. 11, alert notification is executed on the monitor 90.

Furthermore, the image processing apparatus 70 determines whether or not a consecutive seat abnormality has occurred in the gaming machine 10 in which an unregistered player or an unrecognized player plays (S37). Specifically, when a player identified as a registered player or a non-recognized player is seated in the gaming machine 10 that is connected two or more at approximately the same time, it is determined that the consecutive seating is abnormal.
As a result of the determination, if a consecutive seat abnormality has occurred (S37: YES), the image processing device 70 transmits a notification control signal for executing a warning notification to the hall computer 60 or the income (S39). ).

On the other hand, when the consecutive seat abnormality does not occur (S37: NO), the image processing apparatus 70 determines whether a gaming operation abnormality has occurred in the gaming machine 10 in which an unregistered player or an unrecognized player plays. It is determined whether or not (S38).
As a result of the determination, if no gaming operation abnormality has occurred (S38: NO), the process is terminated. On the other hand, if a gaming operation abnormality has occurred (S38: YES), a notification control signal for executing a warning notification is transmitted to the hall computer 60 and the income (S39).
The hall computer 60 receives the notification control signal from the image processing device 70, and performs a predetermined notification process in the gaming machine 10 corresponding to the gaming machine number (S40). As a result, as shown in FIG. 11, a warning notification is executed on the monitor 90.

  In the above description of the suspicious person detection method, the case of pattern 3, pattern 4, and pattern 6 shown in FIG. 10 has been described. However, the present invention is not limited to this. Thus, it is possible to determine the case of the pattern 1 and the pattern 5 by determining the consecutive seat abnormality. Further, in S31, it is possible to determine the case of the pattern 2 by determining the gaming operation abnormality instead of determining the operation state abnormality.

As described above, according to the gaming machine system, the gaming machine, and the suspicious person detection method of the present embodiment, when the player whose face image is captured is an unregistered player or an unrecognized player, When an abnormal situation related to a game occurs due to an act of a registered player or an unrecognized player, there is a possibility that an unregistered player or an unrecognized player has been or has been cheating Therefore, a suspicious person can be detected by performing a predetermined notification process.
In addition, when an unregistered player or a non-recognized player attends a gaming machine with multiple people at approximately the same time, it can be determined that an abnormal situation related to the game has occurred. It is possible to detect as a suspicious person even when a person sits together and performs an illegal act.
