## Background
CROSS REFERENCE TO RELATED APPLICATIONS
This application is based on and claims the benefit of priority from Japanese Patent Application Nos. 2008-107251, 2008-107252 and 2008-107253, respectively filed on 16 Apr. 2008, the contents of which are incorporated herein by reference.
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a gaming machine including an image display unit and a plurality of game stations, provided for each player, through which the players can participate in a game executed in the image display unit, and a gaming management system that manages a game of the gaming machine.
2. Related Art
Generally, various types of gaming machines are installed at an amusement facility, a casino, and the like. One configuration has been known which is composed of an image display unit and a plurality of game stations (hereinafter, referred to as a station), provided for each player, through which the players can participate in a game executed in the image display unit.
Such a gaming machine includes an image display unit on which a game is executed and a plurality of stations provided around the image display unit. Then, each of the players participates in a game executed on the image display unit at each of the stations. Furthermore, each of the stations is provided with a gaming medium processing unit for processing gaming media (mainly, insertion processing and payout processing) such as money, medals, or the like, used for executing a game, and a bet operation unit for performing a bet operation for a game executed in the image display unit.
For example, a configuration disclosed in Japanese Unexamined Application, Publication No. 2005-317032 has been known as a gaming machine capable of executing the abovementioned game. This gaming machine includes a table-shaped housing, and can project various images (for example, a bet operation image) necessary for a gaming image and a game by way of a projector installed in the housing with respect to the image display unit (a display) installed in a horizontal state. Furthermore, a detection means is provided in the housing which includes a light source irradiating an infrared light toward the image display unit so as to detect various operations (such as a bet operation), which a player executes through the image display unit, and a camera receiving reflected light reflected from a player's finger irradiated by the light source, the finger moving over the image display unit. According to the gaming machine thus configured, a player can participate in a game by performing various operations, for example, by moving the player's finger on the image display unit in a game executed on the image display unit provided on a surface of the housing.
Here, as a first problem, in a gaming machine thus configured as described above, for example, there may be a case in which there is no observer such as a dealer who advances, manages, and monitors a game or in which it is difficult to confirm every operation of all the players even if there is an observer. Therefore, it is difficult for a management party of an amusement facility to recognize potential fraudulence in a game. More specifically, in a case in which such fraudulence may affect a balance status of a gaming machine, the management party of the amusement facility may suffer a substantial loss if the management party cannot recognize it.
The invention in relation to the first problem addresses the abovementioned matter, and thus, it is an object of the present invention to provide a gaming machine and a game management system that can effectively prevent fraudulence in a game and, more specifically, prevent fraudulence which may affect a balance of a gaming machine under a gaming environment where there is substantially no observer.
In addition, as a second problem, in a gaming machine thus configured as described above, there are possibilities that, in a case in which a plurality of stations are provided so that a plurality of players can participate in a game, fairness in a game can be damaged or fraudulent operations are performed.
For example, the abovementioned detection means provided in the housing simply determines whether there is a bet operation by a player and manages the bet operation for each of the stations and, in reality, cannot determine whether the player present at the station of interest has performed the bet operation. Therefore, even in a case in which a person who is not concerned with the station of interest performs an operation accidentally or performs operations maliciously by remote control, the game continues, and thus a bet operation may be accepted and payout processing may be executed.
The invention in response to the second problem addresses the abovementioned matter, and thus, it is an object of the present invention to provide a gaming machine that can specify whether an operation is performed by an actual player with progression of the game.
In addition, as a third problem, in a gaming machine thus configured as described above, for example, there may be a case in which there is no observer such as a dealer who advances, manages, and monitors a game. Therefore, it is difficult for a management party of an amusement facility to visually recognize a gaming status and to recognize potential fraudulence in a game.
The invention in relation to the third problem addresses the abovementioned matter, and thus, it is an object of the present invention to visually recognize a gaming status and potential fraudulence in a game under a gaming environment where there is no observer.

A gaming machine 1 of the present embodiment is configured so that an image display unit 3 is provided on an upper face (a table 2A) of a table-shaped housing 2 and six stations 5 are provided so that six players can play a game therearound. In an amusement facility where a plurality of the gaming machines 1 are installed, a game management system 200 is configured by connecting each of the gaming machines 1 to a host computer 100 together, which configures an external apparatus as described later, as shown in FIG. 10.
A chair 5A is provided at each of the stations of the gaming machines 1. Thus, players seated at each of the stations 5 can participate in various games such as a card game, roulette game, a dice game, and the like, executed at the center of the image display unit 3. The players can participate in a game executed at the center of the display and receive payouts at the end of a game by using gaming media such as medals, coins, paper money, a prepaid card, and the like.
As described above, a game is advanced by way of a control unit provided in the housing 2 and an image projecting means controlled by the control unit. This control unit not only advances a game, but also executes receiving a bet operation by a player at each of the stations and performs paying out of gaming media corresponding to a bet amount to a player when the player wins an award based on a result of the game.
The station 5 may be configured so as to allow the player to participate in a game and perform a bet operation, and includes at least the gaming media receiving unit 7 to which the gaming media is inserted when playing a game and a controller 8 including a plurality of control buttons to which a predetermined instruction is input by the player. It should be noted that, as shown in the drawings, although the controller 8 is provided at a table portion of the housing 2, it may be configured so that functions arising by way of operating a control button are realized through an operated image displayed on the image display unit 3, or conversely, that some of the operations through the image display unit are performed by the control button instead.
As shown in FIG. 4, in the present embodiment, a baccarat game, which is one type of card game, is performed in an image of the image display unit 3. More specifically, a playing area 3A in which cards distributed to “BANKER” and “PLAYER” are shown is provided in the central area of the image display unit 3, and an operation area 3B in which a bet operation can be performed through each of the stations 5 for a game executed in the playing area 3A is provided at the peripheral area of the image display unit 3.
The operation area 3B is one of the components of each of the stations 5. Hence, in the operation area 3B, it is configured that a bet operation screen, a help information screen, and the like are displayed on each of the stations 5. In FIG. 4, all of the stations 5 are set in a state in which the bet operation screens thereof are displayed, and the bet operation screens are configured to include a bet area 3a where a player at each of the stations places a bet on “BANKER”, “PLAYER”, or “DRAW”, a chip display area 3b for displaying chips, a select operation area 3c for selecting a bet, and a credit information display area 3d for displaying information of remaining credits.
In this case, a player can perform a bet operation, for example, by pushing an amount of desired chips among “1”, “15”, “10”, and “100” displayed in the chip display area 3b with a finger, and dragging thereof in the present state to a display area of “BANKER”, “PLAYER”, or “DRAW” in the bet area 3a, or alternatively, without dragging, by pushing, in the present state, any one of “BANKER”, “PLAYER”, or “DRAW” in the bet area 3a with a finger. Then, after the bet operation, the bet operation is fixed by way of pushing the select operation area 3c by finger. It should be noted that, regarding the abovementioned bet operation by a player, specific instructing locations are specified by a sensor unit 20 (described later) provide in the housing 2.
Then, after a game has ended, the amount of credits corresponding to the amount of chips bet is added to the amount of credits that a player currently possesses and the resulting amount of credits is displayed on the credit information display area 3d. 
The gaming media receiving unit 7 is configured so that gaming media having a gaming value, such as medals, coins, paper money, a prepaid card, and the like, is inserted, and is provided at each of the station 5. The player can execute a game with the gaming media thus inserted, and the amount thereof is displayed on the credit information display area 3d. 
The controller 8 is provided at each of the stations 5 and includes buttons that a player operates by pushing with progression of the game. These buttons include, for example, a cash-out button 8a, which is pushed at the end of a game, and a help button 8b. 
The cash-out button 8a is generally pushed at the end of a game. When the cashout button 8a is pushed, the amount of credits corresponding to the amount of gaming media that a player has won in a game and currently possesses is paid out from a payout opening 10, which is provided on a side face of the housing 2. It should be noted that, in a case of inserting or paying out gaming media using a card, value information is overwritten by a reader/writer installed in the gaming media receiving unit 7, and then the card is ejected.
The help button 8b is a button which is pushed by a player when the player needs to know how to operate the game. Immediately after the help button 32 is pushed, a help screen showing various kinds of rules and operating information is displayed on the operation area 3B.
The image display unit 3 is configured with a member having transparency (a transparent screen) and so as to display light irradiated from a back side and, more specifically, a game image (a card image shown in FIG. 4) and an operation image (a bet image shown in FIG. 4) projected from the image projecting means 12 provided on the housing 2. In this case, the image projecting means 12 is configured by a known projector, and has a function of enlarging various images (motion pictures and still pictures) transmitted from the control unit 15 which controls the player's operation at each of the stations by using an image forming means 12 including a magnifier so as to form images on the image display unit 3.
The control unit 15 includes a function for controlling gaming image data and bet operation image data displayed on the image display unit 3 as an image control means, and a function for controlling progression of a game as well as various images displayed on the image display unit 3 as a game control means. This control unit 15 may be configured as a dedicated unit which is preliminarily installed in the housing 2 or may be configured in which a unit such as a personal computer (PC) storing data relating game procedures and various image data is incorporated in the housing 2. Furthermore, this control unit 15 may be configured so as to communicate various information with, for example, a host computer installed in an amusement facility, another gaming device, and the like, communication network such as internet, local area network, and the like.
In addition, a sensor unit 20 is provided in the housing 2 that specifically detects operations (in the present embodiment, locations instructed by a player's finger) by the player seated at each of the stations for advancing a card game.
This sensor unit 20 has a function of an operation detection means and includes a light emitting unit 21 that irradiates a scanning light toward the image display unit 3 and light receiving units (light receiving cameras 22) provided at four positions diagonally around the light emitting unit 21. Then, infrared light is configured to be irradiated from the light emitting unit 21 so as not to be affected by ambient visible light. Furthermore, reflected light from the object operated by the player on the surface of the image display unit 3 is detected by the light receiving camera 22. Then, the camera 22 is configured to detect an amount of light to be changed based on the operation by the player's finger and process the detected signal so as to specify a specific operating location of each of the players.
It should be noted that, by providing a plurality (four) of the light receiving cameras 22, even in a case in which a plurality of the players acts simultaneously, it is possible to specify exact locations for multi-point operating locations based on information relating to an angle of the object (a finger) detected at each camera. In other words, since information relating to an angle of the object can be calculated from the four cameras 22, it is possible to exactly specify the operating locations operated by multi-point operation by combining information relating to an angle at each of the cameras based on a predetermined algorithm.
Furthermore, an image capturing means 30 for capturing an image displayed on the image display unit 3 and a player seated on the chair 5A is provided in the housing 2. This image capturing means 30 is configured with, for example, a CCD camera, and image data thus photographed is converted into electric signals so as to be used for various confirmation processing, verification processing, and the like by, for example, comparing thereof with a reference image with respect to, for example, the presence of a player, operating status of a player, and display status on the image display unit.
In the present embodiment, vertical supporting members 2a are fixed at each corner of the table 2A on the housing 2 and decorative top boards 2b are provided to be substantially parallel with the table 2A at the top of the supporting members 2a, and then frames 2c are provided inside the top boards 2b and a CCD camera 31 configuring the image capturing means is provided. More specifically, the frames 2c provided inside the top boards 2b are, as shown in FIG. 3(a), bridged laterally along the diagonal lines, and the CCD camera 31 is provided above the location corresponding to the center of the image display unit 3.
For example, the CCD camera 31 is configured with a so-called dome camera that is housed in a dome-shaped housing fixed by the frames 2c, and can capture images of predetermined directions (each of the stations 5 and the image display unit 3) periodically by way of a rotating mechanism, tilt mechanism, and the like. Therefore, the CCD camera 31 can capture various images displayed on the image display unit 3 as well as all the players seated at the table 5A.
In addition, the configuration of the CCD camera 31, a mode of installation, an interval of image capturing, and the like, can be modified as appropriate, depending on a method of using the images. For example, as shown in FIG. 3(b), a rectangular frame 2c is provided in the top board 2b, and then each of the CCD cameras 31 can be provided in a direction facing each of the stations 5. As shown in FIG. 3(b), the CCD camera provided in the direction facing each of the stations 5 may photograph a single player by a single CCD camera or may photograph a plurality of players by a single CCD camera. With such a configuration, it is possible to photograph a facial expression of a player as well as the presence of a player. Therefore, it is possible to utilize image data thus photographed for, for example, face-recognition processing.
In addition, it is preferable for the abovementioned image capturing means to be provided so as not to be visually recognized by a player seated at a chair. For example, by forming an opening which is allowed to expose a lens portion solely so as to provide the CCD camera 31, it is possible to capture a necessary image without the player recognizing the camera.
Furthermore, in the housing 2, a speaker for playing music, sound effects, and the like, various lamps, and the like may be provided in addition to the abovementioned image capturing means.
Next, a control system of the gaming machine 1 thus configured as described above is explained with reference to FIGS. 5 to 7.
FIG. 5 is a block diagram showing a schematic configuration of an image processing system for processing images photographed by the abovementioned image capturing means 30. As described above, the image capturing means 30 includes an image display unit 3 and a CCD camera (image capturing device) 31 that can photograph a player, and image capturing signals from the CCD camera 31 are processed by an image processing circuit (image processing means) 40.
The image processing circuit 40 includes: a subject specifying unit 41 that receives photographed signals from the CCD camera and specifies a subject; a brightness calculating unit 42 for converting each pixel of a photographed image of a subject specified by the subject specifying unit 41 into brightness information; a player information processing unit 43 that processes information relating to a player (presence or absence of the player, information relating to operations of the player, facial information, information relating to operations of the player made with the lapse of time, and the like) at each of the stations based on the brightness information calculated by the brightness information calculating unit 42; a gaming image processing unit 45 that processes information relating to a gaming image (such as contents of a gaming image, contents of a bet image, and location information thereof) displayed on the image display unit 3 based on the brightness information calculated by the brightness information calculating unit 42; ROM 46 in which an operation program, reference data to be compared with comparative criteria, masked data for masking unnecessary background images, and the like are stored; RAM 47 having a function of temporarily storing a running program, processed image data, and the like; and a CPU 48 that controls those units. These units are connected with each other via a bus and each of the units is configured to be controlled by the control CPU 48.
More specifically, regarding the image capturing signal photographed by the CCD camera 31, by specifying image information at the subject specifying unit 41 and, for example, by obtaining edge information at the player information processing unit 43, processing data as to whether a player is seated on the chair 5A at one of the stations 5 and data relating to an instructing location that a player operated by hand. Furthermore, based on the image information thus specified, gaming image data (such as image content displayed and displaying location) displayed on the image display unit 3 can be processed at the gaming image processing unit 45.
Furthermore, various processing can be executed by converting the image information thus specified into data including brightness information for each pixel thereof at the brightness calculating unit 42. For example, in the player information processing unit 43, it is possible to obtain data relating to trends in a player's movement by detecting continuity regarding a portion in which differences of the brightness information are continued more than a predetermined threshold based on the photographed image photographed at every predetermined interval, or obtain data relating to identity verification by photographing a face of the player and comparing thereof with a reference image (reference data) stored preliminarily so as to use a correlation therebetween. It should be noted that, in a case in which images are photographed continuously, an image photographed at a prescribed point in time, an image stored in ROM preliminarily, or an image transmitted from another apparatus (such as a host computer) may be used as reference data.
In addition, by deleting an unnecessary background of the image capturing signal photographed by the CCD camera 31 or superimposing masked data stored in the ROM 46 in a case in which displayed contents on the image display unit 3 cannot be identified specifically, it is possible to obtain only an image of the table portion and an image of the player operating at the table. It is also possible to obtain image data (see FIG. 9) that specifies a location of a player present at the station 5 and display contents of the image display unit 3 by transmitting the image data to a main control CPU 51 (described later) and actually combining thereof with image data displayed on the image display unit.
Then, the data relating to the processed image thus obtained is stored in the RAM 47 and transmitted to the main control CPU 51 in the game control means 15A that executes the following card game via an interface 49.
FIG. 6 is a block diagram showing a configuration of the game control means 15A of the control unit 15 that executes a card game.
The game control means 15A includes a main control CPU 51, ROM 52, and a microcomputer which is configured with a bus 54 as a core for transferring data mutually therebetween. Then, the CPU 51 is connected, via an I/O interface 57, with: the image processing circuit 40 that processes an image in which a player seated at each of the stations 5 and displayed contents on the image display unit 3 are photographed; an image control driving circuit 60 that controls various images displayed on the image display unit 3; and an operating location detecting circuit 61 that receives a detected signal from the sensor unit 20, which detects an operating location of a finger (object) of a player seated at each of the stations 5, and specifies the operating location of each of the players specifically; and the like.
The main control CPU 51 of the game control means 15A communicates various data such as bet information, award information, and the like, between each of the stations 5 via the I/O interface 57 and a communication interface 63, and has a function for mainly controlling each of the stations 5 and advancing a game. More specifically, the main CPU 51 specifies bet operation information made at each of the stations 5 through the operating location detecting circuit 61, and then accepts the bet information, executes win determination processing with respect to the chips bet, and calculates the amount of credits that is paid out at each of the stations 5 with reference to a payout table.
Furthermore, the ROM 52 in the game control means 15A is configured with, for example, solid-state memory, and stored therein are a program for realizing a basic function for advancing a baccarat game, a display operation program for controlling various image contents displayed on the image display unit 3 with a progression of a game, a program for receiving and paying out game media and the like, a payout table referred to for executing a baccarat game, and the like.
The RAM 53 is memory for temporarily storing various data computed by the CPU 51, and temporarily stores, for example, information relating to a player's operation (such as bet operating location and an amount of bet) through the controller at each of the stations 5 and an operating screen, information relating to an operating location specified by the operating location detecting circuit 61 for each of the stations 5, image capturing data photographed by the CCD camera 31 which is processed in the image processing circuit 40, data relating to a result of the processing executed by the CPU 51, and the like.
Then, the main control CPU 51 in the game control means 15A executes control processing with a progression of a game, such as control of various driving circuits and displayed images on the image display unit 3.
The image control driving circuit 60 is configured to include program ROM, image ROM, an image control CPU, work RAM, a VDP (video display processor), video RAM, and the like. The image control program and the like, relating to a display of the image display unit 3, is stored in the program ROM, and various image data (pixel data) for forming an image displayed on the image display unit 3 is stored in the image ROM.
In addition, the image control CPU determines an image to be displayed on the image display unit 3 (projector 12) among pixel data stored in the image ROM according to the image control program stored in the program ROM preliminarily based on the parameters set by the CPU 51. Thus, a specific displaying location of a game image (card image) and an operating image (bet image) as shown in FIG. 4, timing for displaying an image with a progression of a game, and the like are controlled by the CPU 51.
In addition, the work RAM is configured as a temporary storage means for when the image control program is executed by the image control CPU, and the VDP forms an image corresponding to displayed contents determined by the image control CPU and projects thereof on the image display unit 3 via the projector 12.
The operating location detecting circuit 61 includes a CPU and the like that executes predetermined computing and has a function of specifying a location of an object (a finger of a player) present at the surface of the image display unit 3 specifically. More specifically, the operating location detecting circuit 61 receives a detected signal from the four cameras 22 of the sensor unit 20 provided in the housing 2 and has a function of specifying a portion where a player actually operated (a specific location instructed by a finger of the player) on the image display unit 3. In this case, the operating location detecting circuit 60 derives angular information of the object thus detected based on detected locations inputted from each of the four cameras 22, and has a function of specifying a location of the finger pointing on the image display unit 3. By using the four cameras 22, it is possible to specify the location exactly based on detection information obtained from each of the cameras, even if a player seated at each of the stations 5 executes instructing operations simultaneously.
Furthermore, the CPU 51 includes an identification processing function for identifying whether a player's operation matches location information obtained at the operating location detecting circuit 61 based on information relating to an operating location of a player which is obtained from the operating location detecting circuit 61 and an operating image of the player which is obtained from the image processing circuit 40.
Moreover, the CPU 51 can communicate information with an external device 100 such as a host computer via the communication interface 63. In this case, it can be assumed that, for example, information relating to operating states of a gaming machine of interest for every prescribed time interval, information relating to payout rates of the gaming media at each of the stations, verification information of players seated at the stations, and the like are transmitted to the external device 100. In addition, it can be assumed that reference image data such as facial information of a player present at an amusement facility, ID information of a card that each of the players possesses, and the like are transmitted from the external device.
Next, a configuration according to a control system of the station 5 connected with the CPU 31 is described.
FIG. 7 is a block diagram schematically showing a control system of a station 5 according to the present embodiment. The station 5 includes a player-used controller 70 for controlling an operation at the station and the abovementioned peripheral apparatuses (such as the gaming media receiving device 7, the controller 8, and a payout processing device 9).
The player-used controller 70 includes a CPU 71, ROM 72, and RAM 73 for controlling the station and communicates data with the main control CPU 51 in the abovementioned game control means 15A via a communication interface 65.
The ROM 72 is configured with, for example, solid-state memory, and in the station 5, a program for realizing a basic function, various programs necessary for controlling thereof at another station, and the like, are stored.
The RAM 73 is memory for temporarily storing various data computed by the CPU 71, an amount of credits that a player currently possesses, a bet status of chips by the player, and the like.
Furthermore, a payout button 8a and a help button 8b, which are provided at the controller 8 (see FIG. 1), are connected to the CPU 71, respectively, and the CPU 71 controls execution of various corresponding operations based on operational signals outputted such as by pushing each button. Then, an input signal by the player's operation is transmitted to the main control CPU 51.
In addition, a payout processing device 9 is connected to the CPU 71, and it is possible to pay out gaming media such as medals from the payout opening 10 based on a payout instruction signal from the CPU 71. Moreover, the gaming media receiving device 7 to which the gaming media such as coils, medals, and the like is connected to the CPU 71. The gaming value information (credit information) transmitted from the gaming media receiving device 7 is stored in the RAM 73. Then, the payout information from the payout processing device 9 and the gaming value information (credit information) transmitted from the gaming media receiving device 7 are transmitted to the CPU 51 as balance status information with respect to the gaming machine 1.
The gaming machine 1 with this configuration is configured so as to monitor the overall balance status of the gaming machine 1 by the CPU 51 based on the abovementioned balance information transmitted from each of the stations 5 (in this sense, the CPU 51 has a function as an earning and expense state monitoring means). Here, the balance state indicates a balance of a gaming value in relation to an amount of a gaming value paid out to a player according to a game result compared with a gaming value paid for a game by way of a bet operation. In addition, the CPU 51 of the gaming machine 1 can determine fraudulence or an error of a game by comparing such a balance status with a running state of the gaming machine 1 (in this sense, the CPU 51 has a function as a determination means for determining fraudulence or an error in a game). Here, an operating state indicates an operational state of the gaming machine 1 based on operating signals from the operating location detecting circuit 60, the image processing circuit 40, each of the stations, and the like, more specifically, a detecting signal from the sensor unit 20 which is an operation detection means, a image capturing signal from the image capturing means 30 (the CCD camera 31), an operation input signal from each of the stations 20 (running information), and the like.
FIG. 8 is a flowchart showing an example of monitoring and determination processing by the CPU 51 that monitors a balance status of the gaming machine 1 and determines fraudulence or an error in a game. It should be noted that the monitoring and determination processing is executed so as to be interrupted for a prescribed time interval after the gaming machine 1 starts running, and then a prescribed time lapses.
As shown in the drawing, the CPU 51 initially obtains the abovementioned operation information (Step S1), and subsequently obtains the abovementioned balance status information (Step S2). Then, the CPU 51 compares the operation information thus obtained with the balance status information thus obtained (Step S3). At this time, this information is recognized as data shown in FIG. 9, for example, in the CPU 51, and the CPU 51 determines a balance status based on these data. In the examples of data configuration shown in FIG. 9, an insertion state of gaming media generates a graph with an upward line from left to right as shown in FIG. 9(a), a payout state of gaming media (based on a payout state from the payout processing device 9) generates a graph with an upward line from left to right as shown in FIG. 9(b), and a balance status forms the shape of the graph shown in FIG. 9(c).
The CPU 51 finally determines whether there is an irregularity in the balance status information based on comparison between the balance statuses (Step S4). Then, in the determination, for example, in a case in which the balance status data thus obtained (a data line shown as a solid line in FIG. 9(c)) is deviated from an balance transitional line (shown as a dashed line in FIG. 9(c)) as a criterion (in a case in which the determination in Step S4 is a YES determination), the CPU 51 determines that there is an irregularity in the balance status information, i.e. the CPU 51 recognizes that there is fraudulence or an error, and then notifies thereof (Step S5). Furthermore, in a case in which the determination in Step S4 is a NO determination, the CPU 51 continues the monitoring state in which the game is monitored without notification. It should be noted that the notification may be executed in the form of a sound and visual display using a speaker, a lamp, and the like as a notification means which configures the external device 100, or alternatively, the information regarding the notification may be transmitted to the external device 100 such as a host computer.
Furthermore, the abovementioned monitoring and determination processing may be executed at the host computer (see FIG. 10) as an external device that collectively controls all the gaming machine 1. That is, the host computer 100 executes the same process flow as that of the flowchart in FIG. 8, which is described based on the running information and the balance status information transmitted from the CPU 51 of each of the gaming machines 1. In this case, a management party of the amusement facility can know the balance status, for example, up until 50 hours ago (or more before it), in the form of the display mode shown in FIG. 9, via the display device 100A connected to the host computer 100.
As described above, according to the gaming machine 1 of the present embodiment, since a balance status of gaming media can be monitored by the CPU 51 as the balance status monitoring means, even though there is no observer such as a dealer who advances, manages, and monitors a game or it is difficult to confirm every action of all the players even, if there is an observer, the present invention can effectively prevent fraudulence which may otherwise affect a balance status of a gaming machine. Moreover, in the present configuration, since an operating state is recognized based on a bet operation by a player and a live image of the player by using the sensor unit 20 as the operation detection means and the image capturing means, respectively, and then, the operating state is compared with a balance status, it is easy to determine fraudulence or an error in a game, which can effectively prevent fraudulence reliably and effectively which may otherwise affect a balance status of a gaming machine.
Furthermore, in the present embodiment, in a case in which a game is determined to have fraudulence or an error, the CPU 51 notifies thereof. Therefore, the fraudulence or error of the game can be easily recognized.
Furthermore, according to the gaming management system 200 of the present embodiment, a balance status of gaming values at a plurality of the gaming machines 1 can be collectively monitored at the host computer 100, even though there is no observer such as a dealer who advances, manages, and monitors a game at each of the gaming machines 1 or it is difficult to confirm every action of all the players, even if there is an observer, the present invention can effectively and collectively prevent fraudulence which may otherwise affect a balance status of a plurality of the gaming machines, i.e. the entire amusement facility.
Furthermore, according to the gaming management system 200 of the present embodiment, since a running state for each of the gaming machines 1 is recognized based on a bet operation by a player and a live image of the player by using the sensor unit 20 as the operation detection means and the image capturing means, respectively, and then, the operating state is compared with a balance status, it is easy to determine fraudulence or an error in a game, which can effectively prevent fraudulence reliably and effectively which may otherwise affect a balance status of the entire amusement facility.
Furthermore, according to the gaming management system 200 of the present embodiment, in a case in which a game is determined to have fraudulence or an error, the information regarding the determination is notified on the host computer side. Therefore, the fraudulence or error in the game can be easily and collectively recognized on, for example, a management party side of the amusement facility.
In the foregoing, although the gaming machines according to the present invention are described, the present invention is not limited thereto, and may have various modifications thereto.
For example, a configuration of the gaming machine and an object for specifying an operating location can be modified as appropriate. For example, the object is not limited thereto, and a configuration may be made which specifies a location of an operation item that a player handles. Furthermore, although the image display unit 3 is configured so as to project a game image by way of the projector provided in the housing 2, the present invention may be configured with a liquid crystal display and the like. Furthermore, a configuration of the station 5 in which a game is executed and an operation device may be modified as appropriate, depending on a game executed.
The descriptions regarding the first embodiment are provided above.
In the following, an example of a configuration of a gaming machine according to the present invention (a second example) is described in detail.
FIG. 1A is a perspective view of an overall configuration of an embodiment of a gaming machine. FIG. 2A is a schematic view of an internal configuration of a gaming machine. FIG. 3A shows a location of an image capturing means and, more specifically, FIG. 3A(a) shows the image capturing means being disposed at a central location and FIG. 3A(b) shows a modified example of a location of the image capturing means. FIG. 4A shows an example of a game performed on an image display unit.
A gaming machine 1 of the present embodiment is configured so that an image display unit 3 is provided on an upper face (a table 2A) of a table-shaped housing 2 and six stations 5 are provided so that six players can play a game therearound. A chair 5A is provided at each of the stations. Thus, players seated on each of the stations 5 can participate in various games such as a card game, roulette game, a dice game, and the like, executed at the center of the image display unit 3. The players can participate in a game executed at the center of the display and receive payouts at the end of a game by using gaming media such as medals, coins, paper money, a prepaid card, and the like.
As described above, a game is advanced by way of a control unit provided in the housing 2 and an image projecting means controlled by the control unit. This control unit not only advances a game, but also executes receiving a bet operation by a player at each of the stations and performs paying out of gaming media corresponding to a bet amount to a player when the player wins an award based on a result of the game.
The station 5 may be configured so as to allow the player to participate in a game and perform a bet operation, and includes at least the gaming media receiving unit 7 to which the gaming media is inserted when playing a game and a controller 8 including a plurality of control buttons to which a predetermined instruction is input by the player. It should be noted that, as shown in the drawings, although the controller 8 is provided at a table portion of the housing 2, it may be configured so that functions arising by way of operating a control button are realized through an operated image displayed on the image display unit 3, or conversely, that some of the operations through the image display unit are performed by the control button instead.
As shown in FIG. 4A, in the present embodiment, a baccarat game, which is one type of card game, is performed in an image of the image display unit 3. More specifically, a playing area 3A in which cards distributed to “BANKER” and “PLAYER” are shown is provided in the central area of the image display unit 3, and an operation area 3B in which a bet operation can be performed through each of the stations 5 can be performed for a game executed in the playing area 3A is provided at the peripheral area of the image display unit 3.
The operation area 3B is one of the components of each of the stations 5. Hence, in the operation area 3B, it is configured that a bet operation screen, a help information screen, and the like are displayed on each of the stations 5. In FIG. 4A, all of the stations 5 are set in a state in which the bet operation screens thereof are displayed, and the bet operation screens are configured to include a bet area 3a where a player at each of the stations places a bet on “BANKER”, “PLAYER”, or “DRAW”, a chip display area 3b for displaying chips, a select operation area 3c for selecting a bet, and a credit information display area 3d for displaying information of remaining credits.
In this case, a player can perform a bet operation, for example, by pushing an amount of desired chips among “1”, “5”, “10”, and “100” displayed in the chip display area 3b with a finger, and dragging thereof, in the present state, to a display area of “BANKER”, “PLAYER”, or “DRAW” in the bet area 3a, or alternatively, without dragging, by pushing any one of “BANKER”, “PLAYER”, or “DRAW” in the bet area 3a, in the present state, with a finger. Then, after the bet operation, the bet operation is fixed by way of pushing the select operation area 3c using a player's finger. It should be noted that, regarding the abovementioned bet operation by a player, specific instructing locations are specified by a sensor unit 20 (described later) provide in the housing 2.
Then, after a game has ended, the amount of credits corresponding to the amount of chips bet is added to the amount of credits that a player currently possesses and the resulting amount of credits is displayed on the credit information display area 3d. 
The gaming media receiving unit 7 is configured so that gaming media having a gaming value, such as medals, coins, paper money, prepaid card, and the like, is inserted, and is provided at each of the station 5. The player can execute a game with the gaming media thus inserted, and the amount thereof is displayed on the credit information display area 3d. 
The controller 8 is provided at each of the stations 5 and includes buttons that a player operates by pushing with a progression of the game. These buttons include, for example, a cash-out button 8a, which is pushed at the end of a game, and a help button 8b. 
The cash-out button 8a is generally pushed at the end of a game. When the cashout button 8a is pushed, the amount of credits corresponding to the amount of gaming media that a player has won in a game and currently possesses is paid out from a payout opening 10, which is provided on a side face of the housing 2. It should be noted that, in a case of inserting or paying out gaming media using a card, value information is overwritten by a reader/writer installed in the gaming media receiving unit 7, and then the card is ejected.
The help button 8b is a button which is pushed by a player when the player needs to know how to operate the game. Immediately after the help button 32 is pushed, a help screen showing various kinds of rules and operating information is displayed on the operation area 3B.
The image display unit 3 is configured with a member having transparency (a transparent screen) so as to display light irradiated from a back side and, more specifically, a game image (a card image shown in FIG. 4A) and an operation image (a bet image shown in FIG. 4A) projected from the image projecting means 12 provided on the housing 2. In this case, the image projecting means 12 is configured by a known projector, and has a function of enlarging various images (motion pictures and still pictures) transmitted from the control unit 15 which controls the player's operation at each of the stations by using an image forming means 12 including a magnifier so as to form images on the image display unit 3.
The control unit 15 includes functions for controlling gaming image data and bet operation image data displayed on the image display unit 3 as an image control means and a function for controlling a progression of a game as well as various images displayed on the image display unit 3 as a game control means. This control unit may be configured as a dedicated unit which is preliminarily installed in the housing 2 or may be configured in which a unit such as a personal computer (PC) storing data relating game procedures and various image data is incorporated in the housing 2. Furthermore, this control unit 15 may be configured so as to communicate various information with, for example, a host computer installed in an amusement facility, another gaming device, and the like, communication network such as internet, local area network, and the like.
In addition, a sensor unit 20 is provided in the housing 2 that specifically detects operations (in the present embodiment, locations instructed by a player's finger) by the player seated at each of the stations for advancing a card game.
This sensor unit 20 has a function of an operation detection means and includes a light emitting unit 21 that irradiates a scanning light toward the image display unit 3 and light receiving units (light receiving cameras 22) provided at four positions diagonally around the light emitting unit 21. Then, infrared light is configured to be irradiated from the light emitting unit 21 so as not to be affected by ambient visible light. Although the sensor unit 20 is described as an infrared sensor unit here, it may be configured with a white light source and a camera. Furthermore, reflected light from the object operated by the player on the surface of the image display unit 3 is detected by the light receiving camera 22. Then, the camera 22 is configured to detect an amount of light to be changed based on the operation by the player's finger and process the detected signal so as to specify a specific operating location of each of the players.
It should be noted that, by providing a plurality (four) of the light receiving cameras 22, even in a case in which a plurality of the players make an operation simultaneously, it is possible to specify exact locations for multi-point operating locations based on information relating to an angle of the object (a finger) detected at each camera. In other words, since information relating to an angle of the object can be calculated from the four cameras 22, it is possible to exactly specify the operating locations operated by multi-point operation by way of combining information relating to an angle at each of the cameras based on a predetermined algorithm.
Furthermore, an image capturing means 30 for capturing an image displayed on the image display unit 3 and a player seated on the chair 5A is provided in the housing 2. This image capturing means 30 is configured with, for example, a CCD camera, and image data thus photographed is converted into electric signals so as to be used for various confirmation processing, verification processing, and the like by, for example, comparing thereof with a reference image with respect to, for example, the presence of a player, operating status of a player, and display status on the image display unit.
In the present embodiment, vertical supporting members 2a are fixed at each of the corners of the table 2A on the housing 2 and decorative top boards 2b substantially parallel with the table 2A are provided at the top of the supporting members 2a, and then frames 2c are provided inside the top boards 2b and a CCD camera 31 configuring the image capturing means is provided. More specifically, the frames 2c provided inside the top boards 2b are, as shown in FIG. 3A(a), bridged laterally along the diagonal lines, and the CCD camera 31 is provided above the location corresponding to the center of the image display unit 3.
For example, the CCD camera 31 is configured with a so-called dome camera that is housed in a dome-shaped housing fixed by the frames 2c, and can capture images of predetermined directions (each of the stations 5 and the image display unit 3) periodically by way of a rotating mechanism, tilt mechanism, and the like. Therefore, the CCD camera 31 can capture various images displayed on the image display unit 3 as well as all the players seated at the table 5A.
In addition, the configuration of the CCD camera 31, a mode of installation, an interval of image capturing, and the like, can be modified as appropriate, depending on a method of using the images. For example, as shown in FIG. 3A(b), a rectangular frame 2c is provided in the top board 2c, and then each of the CCD cameras 31 can be provided in a direction facing each of the stations 5. As shown in FIG. 3A(b), the CCD camera provided in the direction facing each of the stations 5 may photograph a single player by a single CCD camera or may photograph a plurality of players by a single CCD camera. With such a configuration, it is possible to photograph a facial expression of a player as well as the presence of a player. Therefore, it is possible to utilize image data thus photographed for, for example, face-recognition processing.
In addition, it is preferable for the abovementioned image capturing means to be provided so as not to be visually recognized by a player seated at a chair. For example, by forming an opening which only exposes a lens portion so as to provide the CCD camera 31, it is possible to capture a necessary image without the player recognizing the camera.
Furthermore, in the housing 2, a speaker for playing music, sound effects, and the like, various lamps, and the like may be provided in addition to the abovementioned image capturing means.
Next, a control system of the gaming machine 1 thus configured as described above is explained with reference to FIGS. 5A to 7A.
FIG. 5A is a block diagram showing a schematic configuration of an image processing system for processing images photographed by the abovementioned image capturing means 30.
As described above, the image capturing means 30 includes an image display unit 3 and a CCD camera (image capturing device) 31 that can photograph a player, and image capturing signals from the CCD camera 31 are processed by an image processing circuit (image processing means) 40.
The image processing circuit 40 includes: a subject specifying unit 41 that receives photographed signals from the CCD camera and specifies a subject; a brightness calculating unit 42 for converting each pixel of a photographed image of a subject specified by the subject specifying unit 41 into brightness information; a player information processing unit 43 that processes information relating to a player (presence or absence of the player, information relating to operations of the player, facial information, information relating to operations of the player made with the lapse of time, and the like) at each of the stations based on the brightness information calculated by the brightness information calculating unit 42; a gaming image processing unit 45 that processes information relating to a gaming image (such as contents of a gaming image, contents of a bet image, and location information thereof) displayed on the image display unit 3 based on the brightness information calculated by the brightness information calculating unit 42; ROM 46 in which an operation program, reference data to be compared with comparative criteria, masked data for masking unnecessary background images, and the like are stored; RAM 47 having a function of temporarily storing a running program, processed image data, and the like; and a CPU 48 that controls those units. These units are connected with each other via a bus and each of the units is configured to be controlled by the control CPU 48.
More specifically, regarding the image capturing signal photographed by the CCD camera 31, by specifying image information at the subject specifying unit 41 and, for example, by obtaining edge information at the player information processing unit 43, processing data as to whether a player is seated on the chair 5A at one of the stations 5 and data relating to an instructing location that a player operated by hand. Furthermore, based on the image information thus specified, gaming image data (such as image content displayed and a displaying location) displayed on the image display unit 3 can be processed at the gaming image processing unit 45.
Furthermore, various processing can be executed by converting the image information thus specified into data including brightness information for each pixel thereof at the brightness calculating unit 42. For example, in the player information processing unit 43, it is possible to obtain data relating to trends in a player's movement by detecting continuity regarding a portion in which differences of the brightness information are continued more than a predetermined threshold based on the photographed image photographed at every predetermined interval, or obtain data relating to identity verification by photographing a face of the player and comparing thereof with a reference image (reference data) stored preliminarily so as to use a correlation therebetween. It should be noted that, in a case in which images are photographed continuously, an image photographed at a prescribed point in time, an image stored in ROM preliminarily, or an image transmitted from another apparatus (such as a host computer) may be used as reference data.
In addition, by deleting an unnecessary background of the image capturing signal photographed by the CCD camera 31 or superimposing masked data stored in the ROM 46 in a case in which displayed contents on the image display unit 3 cannot be identified specifically, it is possible to obtain only an image of the table portion and an image of the player operating at the table. It is also possible to obtain image data (see FIG. 9A) that specifies a location of a player present at the station 5 and displayed contents of the image display unit 3 by transmitting the image data to a main control CPU (described later) and actually combining thereof with image data displayed on the image display unit.
Then, the data relating to the processed image thus obtained is stored in the RAM 47 and transmitted to the main control CPU 51 in the game control means 15A that executes the following card game via an interface 49.
FIG. 6A is a block diagram showing a configuration of a game control means 15A of a control unit 15 that executes a card game.
The game control means 15A includes a main control CPU 51, ROM 52, and a microcomputer which is configured with a bus 54 as a core for transferring data mutually therebetween. Then, the CPU 51 is connected, via an I/O interface 57, with: the image processing circuit 40 that processes an image in which a player seated at each of the stations 5 and displayed contents on the image display unit 3 are photographed; an image control driving circuit 60 that controls various images displayed on the image display unit 3; and an operating location detecting circuit 61 that receives a detected signal from the sensor unit 20, which detects an operating location of a finger (object) of a player seated at each of the stations 5 and specifies the operating location of each of the players specifically; and the like.
The main control CPU 51 of the game control means 15A communicates various data such as bet information, award information, and the like, between each of the stations 5 via the I/O interface 57 and a communication interface 63, and has a function for mainly controlling each of the stations 5 and advancing a game. More specifically, the main CPU 51 specifies bet operation information made at each of the stations 5 through the operating location detecting circuit 61 and then accepts the bet information, executes win determination processing with respect to the chips bet, and calculates the amount of credits that is paid out at each of the stations 5 with reference to a payout table.
Furthermore, the ROM 52 in the game control means 15A is configured with, for example, a solid-state memory, and stored therein are, a program for realizing a basic function for advancing a baccarat game, a display operation program for controlling various image contents displayed on the image display unit 3 with a progression of a game, a program for receiving and paying out game media and the like, a payout table referred to for executing a baccarat game, and the like.
The RAM 53 is memory for temporarily storing various data computed by the CPU 51, and temporarily stores, for example, information relating to a player's operation (such as bet operating location and an amount of bet) through the controller at each of the stations 5 and an operating screen, information relating to an operating location specified by the operating location detecting circuit 61 for each of the stations 5, image capturing data photographed by the CCD camera 31 which is processed in the image processing circuit 40, data relating to a result of the processing executed by the CPU 51, and the like.
Then, the main control CPU 51 in the game control means 15A executes controlling processing with a progression of a game, such as control of various driving circuits and displayed images on the image display unit 3.
The image control driving circuit 60 is configured to include program ROM, image ROM, an image control CPU, work RAM, a VDP (video display processor), video RAM, and the like. The image control program and the like relating to a display of the image display unit 3 is stored in the program ROM, and various image data (pixel data) for forming an image displayed on the image display unit 3 is stored in the image ROM.
In addition, the image control CPU determines an image to be displayed on the image display unit 3 (projector 12) among pixel data stored in the image ROM according to the image control program stored in the program ROM preliminarily based on the parameters set by the CPU 51. Thus, a specific displaying location of a game image (card image) and an operating image (bet image) as shown in FIG. 4A, a timing for displaying an image with a progression of a game, and the like are controlled by the CPU 51.
In addition, the work RAM is configured as a temporary storage means for when executing the image control program is executed by the image control CPU, and the VDP forms an image corresponding to displayed contents determined by the image control CPU and projects thereof on the image display unit 3 via the projector 12.
The operating location detecting circuit 61 includes a CPU and the like that executes predetermined computing and has a function of specifying a location of an object (a finger of a player) present at the surface of the image display unit 3 specifically. More specifically, the operating location detecting circuit 61 receives a detected signal from the four cameras 22 of the sensor unit 20 provided in the housing 2 and has a function of specifying a portion where a player actually operated (a specific location instructed by a finger of the player) on the image display unit 3. In this case, the operating location detecting circuit 60 derives angular information of the object thus detected based on detected locations inputted from each of the four cameras 22, and has a function of specifying a location of the finger pointing on the image display unit 3. By using the four cameras 22, it is possible to specify the location exactly based on detection information obtained from each of the cameras, even if a player seated at each of the stations 5 executes instructing operations simultaneously.
Furthermore, the CPU 51 includes an identification processing function for identifying whether a player's operation matches location information obtained at the operating location detecting circuit 61 based on information relating to an operating location of a player which is obtained from the operating location detecting circuit 61 and an operating image of the player which is obtained from the image processing circuit 40 (this identification processing is described later).
Moreover, the CPU 51 can communicate information with an external device 100 such as a host computer via the communication interface 63. In this case, it can be assumed that, for example, information relating to running states of a gaming machine of interest for every prescribed time interval, information relating to payout rates of the gaming media at each of the stations, verification information of players seated at the stations, and the like are transmitted to the external device 100. In addition, it can be assumed that reference image data such as a facial information of a player present at an amusement facility, ID information of a card that each of the players possesses, and the like are transmitted from the external device.
Next, a configuration according to a control system of the station 5 connected with the CPU 31 is described.
FIG. 7A is a block diagram schematically showing a control system of a station 5 according to the present embodiment. The station 5 includes a player-used controller 70 for controlling an operation at the station and the abovementioned peripheral apparatuses (such as the gaming media receiving device 7, the controller 8, and a payout processing device 9).
The player-used controller 70 includes a CPU 71, ROM 72, and RAM 73 for controlling the station and communicates data with the main control CPU 31 in the abovementioned game control means 15A via a communication interface 65.
The ROM 72 is configured with, for example, a solid-state memory, and in the station 5, a program for realizing a basic function, various programs necessary for controlling thereof at another station, and the like, are stored.
The RAM 73 is memory for temporarily storing various data computed by the CPU 71, an amount of credits that a player currently possesses, a bet status of chips by the player, and the like.
Furthermore, a payout button 8a and a help button 8b, which are provided at the controller 8 (see FIG. 1A), are connected to the CPU 71, respectively, and the CPU 71 controls execution of various corresponding operations based on operational signals outputted such as by pushing each button. Then, an input signal by the player's operation is transmitted to the main control CPU 31.
In addition, a payout processing device 9 is connected to the CPU 71, and it is possible to pay out gaming media such as medals from the payout opening 10 based on a payout instruction signal from the CPU 71. Moreover, the gaming media receiving device 7 to which the gaming media such as coils, medals, and the like is connected to the CPU 71. The gaming value information (credit information) transmitted from the gaming media receiving device 7 is stored in the RAM 73.
As described above, in the gaming machine 1 in which the CCD camera 31 is provided as an image capturing means, it is determined as to whether the player who placed a bet is seated on a station of interest when a bet operation was made at the station. This determination can be executed based on operating location information from the abovementioned operating location detecting circuit 61 and player image information from the image processing circuit 40, and the determination processing is executed in the main control CPU 51 of the game control means 15A. That is, the CPU 51 has a function for determining whether bet operation information at each of the stations is performed by a player present at a station of interest as a determination means.
In the following, a procedure of the determination means executed in the CPU 51 is described with reference to a flowchart in FIG. 8A.
Initially, receiving processing such as displaying a bet operation image at each of the stations 5 is executed at the beginning of a game (ST01). A bet operation performed by a player is detected by the sensor unit 20, and the operating location thereof is detected at the operating location detecting circuit 61 (ST02). A specific bet location in each of the bet areas 3a on the bet operating screen is specified preliminarily. Therefore, when the operation is detected at the specific location, it is recognized that the bet operation is performed at a station corresponding to the operating location thus detected.
Next, a player operation image when the operating location was detected is obtained from the image capturing data by the CCD camera 31 (ST03). As shown in FIG. 9A, the image thus obtained shows a state in which a player P seated at a station operates the bet area 3a on the bet screen. This image data may be image data photographed by the CCD camera 31 or data in which the image data photographed by the CCD camera 31 is masked and superimposed with game image data and bet image data displayed on the image display unit 3, as described above.
Then, whether the player was seated on the station corresponding to the operating location specified by the operating location detecting circuit 61 and operated, i.e. whether the operating location thus detected corresponds to the player, is determined (ST04).
In this determination processing, in a case in which the operating location thus detected corresponds to the player (ST04, YES), start processing of a game is executed successively (ST06). Furthermore, in this determination processing, in a case in which the operating location thus detected does not correspond to the player (ST04, NO), it is recognized that the bet operation processing at the station was performed fraudulently or erroneously, the bet processing at the station is invalidated (ST05), and then, start processing of a game is executed afterward (ST06).
According to the abovementioned gaming machine, when each of the players performs a bet operation at each of the stations 5, the CCD camera 31 provided above photographs a bet operation of the player, and thus, an actual player is identified by using the player capturing information and actual bet information. Therefore, it is possible to detect an erroneous operation or a fraudulent operation by a person other than the player present at the station.
Furthermore, in a case in which it is determined that a bet operation is erroneous, the gaming machine 1 not only invalidates the bet processing at the station, but also notifies thereof by way of, for example, sound or a lamp, or alternatively, the information regarding the notification may be transmitted to an external device such as a host computer.
In the foregoing, although the gaming machines according to the present invention are described, the present invention is not limited thereto, and may have a variety of modifications thereto.
For example, a configuration of the gaming machine and an object for specifying an operating location can be modified as appropriate. For example, it is not limited to a hand of a player, and a configuration may be made which specifies a location of an operation item that a player handles. Furthermore, although the image display unit 3 is configured so as to project a game image by way of the projector provided in the housing 2, the present invention may be configured with a liquid crystal display and the like. Furthermore, a configuration of the station 5 in which a game is executed and an operation device may be modified as appropriate, depending on a game executed.
The descriptions regarding the second embodiment are provided above.
In the following, an example of a configuration of a gaming machine according to the present invention (a third example) is described in detail.
FIG. 1B is a perspective view of an overall configuration of an embodiment of a gaming machine. FIG. 2B is a schematic view of an internal configuration of a gaming machine. FIG. 3B shows a location of an image capturing means and, more specifically, FIG. 3B(a) shows the image capturing means being disposed at a central location and FIG. 3B(b) shows a modified example of a location of the image capturing means. FIG. 4B shows an example of a game performed on an image display unit.
A gaming machine 1 of the present embodiment is configured so that an image display unit 3 is provided on an upper face (a table 2A) of a table-shaped housing 2 and six stations 5 are provided so that six players can play a game therearound. A chair 5A is provided at each of the stations. Thus, players seated on each of the stations 5 can participate in various games such as a card game, roulette game, a dice game, and the like, executed at the center of the image display unit 3. The players can participate in a game executed at the center of the display and receive payouts at the end of a game by using gaming media such as medals, coins, paper money, a prepaid card, and the like.
As described above, a game is advanced by way of a control unit provided in the housing 2 and an image projecting means controlled by the control unit. This control unit not only advances a game but also executes receiving a bet operation by a player at each of the stations and performs paying out of gaming media corresponding to a bet amount to a player when the player wins an award based on a result of the game.
The station 5 may be configured so as to allow the player to participate in a game and perform a bet operation, and includes at least the gaming media receiving unit 7 to which the gaming media is inserted when playing a game and a controller 8 including a plurality of control buttons to which a predetermined instruction is input by the player. It should be noted that, as shown in the drawings, although the controller 8 is provided at a table portion of the housing 2, it may be configured so that functions arising by way of operating a control button are realized through an operated image displayed on the image display unit 3, or conversely, that some of the operations through the image display unit are performed by the control button instead.
As shown in FIG. 4B, in the present embodiment, a baccarat game, which is one type of card games is performed in an image of the image display unit 3. More specifically, a playing area 3A in which cards distributed to “BANKER” and “PLAYER” are shown is provided in the central area of the image display unit 3, and an operation area 3B in which a bet operation can be performed through each of the stations 5 can be performed for a game executed in the playing area 3A is provided at the peripheral area of the image display unit 3.
The operation area 3B is one of the components of each of the stations 5. Hence, in the operation area 3B, it is configured that a bet operation screen, a help information screen, and the like are displayed on each of the stations 5. In FIG. 4B, all of the stations 5 are set in a state in which the bet operation screens thereof are displayed and the bet operation screens are configured with to include a bet area 3a where a player at each of the stations places a bet on “BANKER”, “PLAYER”, or “DRAW”, a chip display area 3b for displaying chips, a select operation area 3c for selecting a bet, and a credit information display area 3d for displaying information of remaining credits.
In this case, a player can perform a bet operation, for example, by pushing an amount of the desired chips among “1”, “5”, “10”, and “100” displayed in the chip display area 3b with a finger, and dragging thereof, in the present state, to a display areas of “BANKER”, “PLAYER”, or “DRAW” in the bet area 3a, or alternatively, without dragging by pushing any one of “BANKER”, “PLAYER”, or “DRAW” in the bet area 3a, in the present state, with a finger. Then, after the bet operation, the bet operation is fixed by way of pushing the select operation area 3c using a player's finger. It should be noted that, regarding the abovementioned bet operation by a player, specific instructing locations are specified by a sensor unit 20 (described later) provide in the housing 2.
Then, after a game has ended, the amount of credits corresponding to the amount of chips bet is added to the amount of credits that a player currently possesses and the resulting amount of credits is displayed on the credit information display area 3d. 
The gaming media receiving unit 7 is configured so that gaming media having a gaming value, such as medals, coins, paper money, prepaid card, and the like, is inserted, and is provided at each of the station 5. The player can execute a game with the gaming media thus inserted, and the amount thereof is displayed on the credit information display area 3d. 
The controller 8 is provided at each of the stations 5 and includes buttons that a player operates by pushing with a progression of the game. These buttons include, for example, a cashout button 8a, which is pushed at the end of a game, and a help button 8b. 
The cashout button 8a is generally pushed at the end of a game. When the cashout button 8a is pushed, the amount of credits corresponding to the amount of gaming media that a player has won in a game and currently possesses is paid out from a payout opening 10, which is provided on a side face of the housing 2. It should be noted that, in a case of inserting or paying out gaming media using a card, value information is overwritten by a reader/writer installed in the gaming media receiving unit 7, and then the card is ejected.
The help button 8b is a button which is pushed by a player when the player needs to know how to operate the game. Immediately after the help button 32 is pushed, a help screen showing various kinds of rules and operating information is displayed on the operation area 3B.
The image display unit 3 is configured with a member having transparency (a transparent screen) and so as to display light irradiated from a back side and more specifically, a game image (a card image shown in FIG. 4B) and an operation image (a bet image shown in FIG. 4B) projected from the image projecting means 12 provided on the housing 2. In this case, the image projecting means 12 is configured by a known projector, and has a function of enlarging various images (motion pictures and still pictures) transmitted from the control unit 15 which controls the player's operation at each of the stations by using an image forming means 12 including a magnifier so as to form images on the image display unit 3.
The control unit 15 includes functions as an image control means for controlling gaming image data and bet operation image data displayed on the image display unit 3 and a function for controlling a progression of a game as well as various images displayed on the image display unit 3 as a game control means. This control unit 15 may be configured as a dedicated unit which is preliminarily installed in the housing 2 or may be configured in which a unit such as a personal computer (PC) storing data relating game procedures and various image data is incorporated in the housing 2. Furthermore, this control unit 15 may be configured so as to communicate various information with, for example, a host computer installed in an amusement facility, another gaming device, and the like, communication network such as internet, local area network, and the like.
In addition, a sensor unit 20 is provided in the housing 2 that specifically detects operations (in the present embodiment, locations instructed by a player's finger) by the player seated at each of the stations for advancing a card game.
This sensor unit 20 has a function of an operation detection means and includes a light emitting unit 21 that irradiates a scanning light toward the image display unit 3 and light receiving units (light receiving cameras 22) provided at four positions diagonally around the light emitting unit 21. Then, infrared light is configured to be irradiated from the light emitting unit 21 so as not to be affected by ambient visible light. Furthermore, reflected light from the object operated by the player on the surface of the image display unit 3 is detected by the light receiving camera 22. Then, the camera 22 is configured to detect an amount of light to be changed based on the operation by the player's finger and process the detected signal so as to specify a specific operating location of each of the players.
It should be noted that, by providing a plurality (four) of the light receiving cameras 22, even in a case in which a plurality of the players acts simultaneously, it is possible to specify exact locations for multipoint operating locations based on information relating to an angle of the object (a finger) detected at each camera. In other words, since information relating to an angle of the object can be calculated from the four cameras 22, it is possible to exactly specify the operating locations operated by multipoint operation by combining information relating to an angle at each of the cameras based on a predetermined algorithm.
Furthermore, an image capturing means 30 for capturing an image displayed on the image display unit 3 and a player seated on the chair 5A is provided in the housing 2. This image capturing means 30 is configured with, for example, a CCD camera, and image data thus photographed is converted into electric signals so as to be used for various confirmation processing, verification processing, and the like by, for example, comparing thereof with a reference image with respect to, for example, the presence of a player, operating status of a player, and display status on the image display unit.
In the present embodiment, vertical supporting members 2a are fixed at each corner of the table 2A on the housing 2 and decorative top boards 2b are provided to be substantially parallel with the table 2A at the top of the supporting members 2a, and then frames 2c are provided inside the top boards 2b and a CCD camera 31 configuring the image capturing means is provided. More specifically, the frames 2c provided inside the top boards 2b are, as shown in FIG. 3B(a), bridged laterally along the diagonal lines, and the CCD camera 31 is provided above the location corresponding to the center of the image display unit 3. In other words, in the present embodiment, supporting members 2a extend upwards from four corners of the housing 2, respectively, and the CCD camera 31 as an image capturing means 30 is supported by the supporting member 2a via the frame 2c at the center of the image display unit 3 which is above the housing 2. That is, the image capturing means 30 is integrally fixed to the housing 2.
For example, the CCD camera 31 is configured with a so-called dome camera that is housed in a dome-shaped housing fixed by the frames 2c, and can capture images of predetermined directions (each of the stations 5 and the image display unit 3) periodically by way of a rotating mechanism, tilt mechanism, and the like. Therefore, the CCD camera 31 can capture various images displayed on the image display unit 3 as well as all the players seated at the table 5A.
It should be noted that the configuration of the CCD camera 31, a mode of installation, an interval of image capturing, and the like, can be modified as appropriate, depending on an application method of the images. For example, as shown in FIG. 3B(b), a rectangular frame 2c is provided in the top board 2b, and then each of the CCD cameras 31 can be provided in a direction facing each of the stations 5. As shown in FIG. 3B(b), the CCD camera provided in the direction facing each of the stations 5 may photograph a single player by a single CCD camera or may photograph a plurality of players by a single CCD camera. With such a configuration, it is possible to photograph a facial expression of a player as well as the presence of a player. Therefore, it is possible to utilize image data thus photographed for, for example, face-recognition processing. In other words, since each of the stations 5 can be photographed directly from the front by way of the image capturing means 30, a face of a player playing at each of the stations 5 can be photographed reliably, thereby enabling visual recognition of a gaming state, fraudulence, and the like reliably for each of the stations 5. Furthermore, as shown as a dashed lines in FIG. 3B(b), the CCD camera 31 configuring the image capturing means 30 may be fixed directly with the supporting member 2a which extends from the housing 2. That is, the CCD camera 31 may be supported by the supporting members 2a at the four corners of the housing 2. With this configuration, a player and a surrounding environment of the image display unit 3 can be photographed diagonally with respect to the image display unit 3, and thus, the player and the surrounding environment of the image display unit 3 can be photographed clearly from the front. Thus, it can enhance visual recognition and can visually recognize a gaming state, fraudulence, and the like reliably.
In addition, it is preferable for the abovementioned image capturing means to be provided so as not to be visually recognized by a player seated at a chair. For example, by forming an opening which only exposes a lens portion so as to provide the CCD camera 31, it is possible to capture a necessary image without the player recognizing the camera.
Furthermore, in the housing 2, a speaker for playing music, sound effects, and the like, various lamps, and the like may be provided in addition to the abovementioned image capturing means.
Next, a control system of the gaming machine 1 thus configured as described above is explained with reference to FIGS. 5B to 7B.
FIG. 5B is a block diagram showing a schematic configuration of an image processing system for processing images photographed by the abovementioned image capturing means 30. As described above, the image capturing means 30 includes an image display unit 3 and a CCD camera (image capturing device) 31 that can photograph a player, and image capturing signals from the CCD camera 31 are processed by an image processing circuit (image processing means) 40.
The image processing circuit 40 includes: a subject specifying unit 41 that receives photographed signals from the CCD camera and specifies a subject; a brightness calculating unit 42 for converting each pixel of a photographed image of a subject specified by the subject specifying unit 41 into brightness information; a player information processing unit 43 that processes information relating to a player (presence or absence of the player, information relating to operations of the player, facial information, information relating to operations of the player made with the lapse of time, and the like) at each of the stations based on the brightness information calculated by the brightness information calculating unit 42; a gaming image processing unit 45 that processes information relating to a gaming image (such as contents of a gaming image, contents of a bet image, and location information thereof) displayed on the image display unit 3 based on the brightness information calculated by the brightness information calculating unit 42; ROM 46 in which an operation program, reference data to be compared with comparative criteria, masked data for masking unnecessary background images, and the like are stored; RAM 47 having a function of temporarily storing a running program, processed image data, and the like; and the CPU 48 that controls those units. These units are connected with each other via a bus and each of the units is configured to be controlled by the control CPU 48.
More specifically, regarding the image capturing signal photographed by the CCD camera 31, by specifying image information at the subject specifying unit 41 and, for example, by obtaining edge information at the player information processing unit 43, processing data as to whether a player is seated on the chair 5A at one of the stations 5 and data relating to a instructing location operated by a player's hand can executed. Furthermore, based on the image information thus specified, gaming image data (such as image contents displayed and a displaying location) displayed on the image display unit 3 can be processed at the gaming image processing unit 45.
Furthermore, various processing can be executed by converting the image information thus specified into data including brightness information for each pixel thereof at the brightness calculating unit 42. For example, at the player information processing unit 43, it is possible to obtain data relating to directions of a player's movement by detecting continuity regarding a portion in which differences of the brightness information are continued more than a predetermined threshold based on the captured image captured in every predetermined interval, or obtain data relating to identity verification by capturing a face of the player and comparing it with a reference image (reference data) stored preliminarily so as to use correlation therebetween. It should be noted that, in a case in which images are photographed continuously, an image photographed at a prescribed point in time, an image stored in ROM preliminarily, or an image transmitted from another apparatus (such as a host computer) may be used as reference data.
In addition, by deleting an unnecessary background of the image capturing signal photographed by the CCD camera 31 or superimposing masked data stored in the ROM 46 in a case in which displayed contents on the image display unit 3 cannot be identified specifically, it is possible to obtain only an image of the table portion and an image of the player operating at the table. It is also possible to obtain image data that specifies a location of a player present at the station 5 and displayed contents of the image display unit 3 by transmitting the image data to a main control CPU 51 (described later) and actually combining thereof with image data displayed on the image display unit.
Then, the data relating to the processed image thus obtained is stored in the RAM 47 and transmitted to the main control CPU 51 in the game control means 15A that executes the following card game via an interface 49.
FIG. 6B is a block diagram showing a configuration of a game control means 15A of a control unit 15 that executes a card game.
The game control means 15A includes a main control CPU 51, ROM 52, and a microcomputer which is configured with a bus 54 as a core for transferring data mutually therebetween. Then, the CPU 51 is connected, via an I/O interface 57, with: the image processing circuit 40 that processes an image in which a player seated at each of the stations 5 and displayed contents on the image display unit 3 are photographed; an image control driving circuit 60 that controls various images displayed on the image display unit 3; and an operating location detecting circuit 61 that receives a detected signal from the sensor unit 20 which detects an operating location of a finger (object) of a player seated at each of the stations 5 and specifies the operating location of each of the players specifically; and the like.
The main control CPU 51 of the game control means 15A communicates various data such as bet information, award information, and the like, between each of the stations 5 via the I/O interface 57 and a communication interface 63, and has a function for mainly controlling each of the stations 5 and advancing a game.
