CROSS-REFERENCE TO THE RELATED APPLICATION(S) 
       [0001]    The present application is based upon and claims priority from prior Japanese Patent Application No. 2007-015298, filed on Jan. 25, 2007, the entire content of which are incorporated herein by reference. 
       TECHNICAL FIELD 
       [0002]    The present invention relates to a game system having a common main display that can be viewed by a plurality of players. 
       BACKGROUND 
       [0003]    An example of conventional multi-player games, such as poker games which use cards or the like, is disclosed in WO-A1-97026061. An example of multi-player-tournament games is disclosed in WO-A1-00071218. An example of game systems for providing award to players through a network in gambling is disclosed in WO-A1-02041233. 
         [0004]    In a game that is played while a plurality of players view a common main display, facial expressions of other players or reactions of audiences (for example, cheers and clamors) viewing the game have an effect on psychology of the players and are considerable factor in playing the game. However, when the players play the game side by side, it is difficult to directly view the facial expressions of other players. Accordingly, it is difficult to guess whether the game proceeds to be advantageous to other players, and thus it is difficult to set up a strategy, and thereby amusement in the game becomes insufficient in terms of tactically playing the game. 
         [0005]    In the above-described games, generally, the players play the games on the front side of the main display. Thus, when the main display is disposed on the wall side, positions in which the audiences can stand are limited to the players&#39; rear side or the player&#39;s side, and thereby it is difficult for the audiences to directly recognize facial expressions of the players visually which change in accordance with the progress of the game. Accordingly, for the audiences viewing the game, amusement of the game becomes insufficient. Furthermore, since it is difficult to visually recognize the facial expressions of the players, reactions of the audiences become insensitive, and thereby a heightened atmosphere of the game cannot be made. 
       SUMMARY 
       [0006]    One of objects of the present invention is to provide a new entertaining feature that cannot be provided by using the conventional technology. In particular, one of objects of the present invention is to provide a game system capable of increasing enjoyment of tactical play in a game and enjoyment of viewing the game and encouraging the whole aspects of the game. 
         [0007]    According to one aspect of the invention, there is provided a game system that provides a game in which a plurality of players participate, the game system including: a first display unit that displays an image related to the game; a plurality of stations that are provided for each of the players to play the game and arranged at positions where the image displayed on the first display unit is viewable by each of the players; a plurality of camera devices that are respectively provided in each of the stations and capture facial images of the respective players; and a controller that operates to: control at least one of the camera devices to capture the facial images; and control the first display unit to display the facial images captured by the camera devices.

         [0106]    After the processes of Steps S 103  and S 104  are performed for all the stations  3 , the process proceeds to Step S 105 . 
         [0107]    In Step S 105 , the CPU  41  receives the selection information from the CPU  51 . Then, in Step S 106 , the CPU  41  displays the selection information received in Step S 105  in the game information display section  35  of the front display  21  and accumulates and stores credits corresponding to the bet chips in the RAM  42  on the basis of the received selection information. 
         [0108]    After the processes of Steps S 105  and S 106  are performed for all the stations  3 , the process proceeds to Step S 107 . 
         [0109]    In Step S 107 , the CPU  41  determines three cards by using random numbers and displays the determined cards as Flop on the table  31  of the front display  21 . 
         [0110]    In Step S 108 , the CPU  41  performs a process for transmitting a command for receiving a selection. This process will be described later in detail with reference to  FIG. 10 . 
         [0111]    In Step S 109 , the CPU  41  receives the selection information from the CPU  51 . Then, in Step S 110 , the CPU  41  displays the selection information received in Step S 109  in the game information display section  35  of the front display  21  and accumulates and stores credits corresponding to the bet chips in the RAM  42  on the basis of the received selection information. 
         [0112]    After the processes of Steps S 108  to S 110  are performed for all the stations  3 , the process proceeds to Step S 111 . 
         [0113]    In Step S 111 , the CPU  41  determines one card by using a random number and displays the determined card as Turn on the table  31  of the front display  21 . 
         [0114]    In Step S 112 , the CPU  41  performs a process for transmitting a command for receiving a selection. 
         [0115]    In Step S 113  shown in  FIG. 9 , the CPU  41  receives selection information from the CPU  51 . Then, in Step S 114 , the CPU  41  displays the selection information received in Step S 113  in the game information display section  35  of the front display  21  and accumulates and stores credits corresponding to the bet chips in the RAM  42  on the basis of the received selection information. 
         [0116]    After the processes of Steps S 112  to S 114  are performed for all the stations  3 , the process proceeds to Step S 115 . 
         [0117]    In Step S 115 , the CPU  41  determines one card by using a random number and displays the determined card as River on the table  31  of the front display  21 . 
         [0118]    In Step S 116 , the CPU  41  performs a process for transmitting a command for receiving a selection. 
         [0119]    In Step S 117 , the CPU  41  receives selection information from the CPU  51 . Then, in Step S 118 , the CPU  41  displays the selection information received in Step S 117  in the game information display section  35  of the front display  21  and accumulates and stores credits corresponding to the bet chips in the RAM  42  on the basis of the received selection information. 
         [0120]    After the processes of Steps S 116  to S 118  are performed for all the stations  3 , the process proceeds to Step S 119 . 
         [0121]    In Step S 119 , the CPU  41  performs a Showdown process. 
         [0122]    In particular, the CPU  41  displays each two cards that have been dealt to a player using each station  3  in the game information display section  35  corresponding to the station  3 . 
         [0123]    In Step S 120 , the CPU  41  compares the hands with one another. 
         [0124]    In particular, first, the CPU  41  determines a strongest hand among hands made by combining two cards dealt to one player and three cards among five cards displayed on the table  31  of the front display  21  as the hand of the player. After the same process as that described above is performed for all the players remaining in the game, the CPU  41  compares the hands of the players to one another and determines a player whose hand is the strongest. 
         [0125]    In Step S 121 , the CPU  41  transmits the payout information to the CPU  51 . 
         [0126]    In particular, the CPU  41  transmits the information on the credit amount accumulatively stored in the RAM  42  to the CPU  51 . 
         [0127]    After the process of Step S 121  is performed, the game process is completed. 
         [0128]      FIG. 10  is a flowchart showing a subroutine for the process for transmitting a command for receiving a selection which is performed by the main control unit in Steps S 108  and S 112  shown in  FIG. 8  and Step S 116  shown in  FIG. 9 . 
         [0129]    In Step S 201 , the CPU  41  transmits a direction signal for receiving a bet selection to the CPU  51 . 
         [0130]    When receiving the direction signal for receiving a bet selection, the station  3  performs a process of receiving the bet selection and a process of transmitting the input selection information to the CPU  41 . 
         [0131]    In Step S 202 , the CPU  41  displays the player&#39;s face image (that is, the face image of a player who has a turn to perform a bet selection) received from the camera  16  of the station  3  that has transmitted the direction signal for receiving a bet selection in Step S 201  in the enlarged face image displaying section  36  of the front display  21 . 
         [0132]    After the process of Step S 202  is performed, the subroutine is completed. 
         [0133]    Next, a process of displaying the face image of a player designated by the player playing a game in the station  3  in the liquid crystal display  10  of the station  3  will be described. 
         [0134]      FIG. 11  is a flowchart showing a subroutine for a process of displaying the face image of a designated player which is performed at regular time intervals by the station and the main control unit, independently of the game process shown in  FIGS. 8 and 9 . 
         [0135]    This subroutine is executed only when an input for designating a player whose face is to be displayed is performed by the player. 
         [0136]    First, in Step S 301 , the CPU  51  of the station  3  determines whether an input for designating a player whose face image is to be displayed is performed by the player. In this process, the CPU  51  determines whether an alphabet in the player selection section  78  (see  FIG. 5 ) is selected through the touch panel  11 . When it is determined that an input for designating the player whose face image is to be displayed is not performed, the process proceeds back to S 301 . 
         [0137]    On the other hand, when it is determined that an input for designating the player whose face image is to be displayed is performed, the CPU  51  determines the designated player in Step S 302 . In this process, the CPU  51  determines which alphabet has been selected in Step S 301 . 
         [0138]    In Step S 303 , the CPU  51  transmits information on the designated player (hereinafter, referred to as designated player information) to the CPU  41  of the main control unit  40 . 
         [0139]    In Step S 401 , the CPU  41  of the main control unit  40  receives the designated player information from the CPU  51  of the station  3 . 
         [0140]    In Step S 402 , the CPU  41  transmits the face image data received from the station  3  in which the designated player plays a game to the CPU  51 . 
         [0141]    Next, in Step S 304 , the CPU  51  of the station  3  receives the face image data of the designated player from the CPU  41 . 
         [0142]    In Step S 305 , the CPU  51  displays the designated player&#39;s face image on the basis of the face image data received in Step S 304  in the designated player face image displaying section  77  of the liquid crystal display  10  of the station  3 . 
         [0143]    In the embodiment, the face image displayed in the designated player face image displaying section  77  continues to be displayed until the end of the game when a player is not newly designated. On the other hand, when a new player is designated, the displayed face image is replaced with the face image of the new player. 
         [0144]    However, a time for displaying the designated player&#39;s face image is not limited to the above-described example. For example, the designated player&#39;s face image may be displayed for a predetermined time. 
         [0145]    After performing the process of Step S 305 , the subroutine is completed. 
         [0146]    As described above, the game system  1  according to the embodiment has the front display  21  (first display unit). The game system  1  has ten stations  3 , which are used for the players to play the game, each including the liquid crystal display  10  (second display unit), the camera  16  for capturing an image of the face of the player playing a game, and the touch panel  11  (an input device) for selecting a player whose face image is to be displayed on the liquid crystal display  10 . The game system  1  has the main control unit  40  (controller) that is programmed to execute the following processes of “(a)” to “(c)”. 
         [0147]    (a) A process of controlling an operation for capturing image of the faces of the players playing the game in the stations  3  having the cameras  16  by using the cameras  16 . 
         [0148]    (b) A process of controlling an operation for displaying images of the players&#39; faces which have been captured by the cameras  16  on the front display  21 . 
         [0149]    (c) A process of controlling an operation for displaying the face image of the player, who is selected by each touch panel  11 , captured by the camera  16  on the liquid crystal displays  10  of each station  3 . 
         [0150]    In the embodiment, although the image capturing operations are continuously performed by the cameras  16 , however, the method of capturing images by the cameras is not limited thereto. For example, the image capturing operations may be performed only at predetermined timings (for example, at a time when a bet selection is made or a card is dealt) or only when a predetermined condition (for example, a condition that the amount of the pot exceeds a predetermined amount or a raise of an amount equal to or larger than a predetermined amount is made) is satisfied. The face image data acquired by the image capturing operations by using the cameras may be stored in the memory. 
         [0151]    Although the face images acquired by the image capturing operations by using the cameras  16  are configured to be continuously displayed on the front display  21  in the embodiment, the present invention is not limited thereto. For example, the face images may be configured to be displayed only at predetermined timings (for example, at a time when a bet selection is made or a card is dealt) or only when a predetermined condition (for example, a condition that the amount of the pot exceeds a predetermined amount or a raise of an amount equal to or larger than a predetermined amount is made) is satisfied. 
         [0152]    Although the face images of all the players participating in the game are configured to be displayed on the front display  21  in the embodiment, the present invention is not limited thereto. For example, only the face image of a player who has a turn to receive a card or make a bet selection may be configured to be displayed on the first display unit. Alternatively, only the face image of a player who satisfies a predetermined condition (for example, a player who makes a raise) is satisfied may be configured to be displayed on the first display unit. 
         [0153]    Although the face image of a player playing the game in the station  3  and the face image of a player designated by the player are configured to be displayed on the liquid crystal display  10  of the station  3  in the embodiment, the face images displayed on the second display unit is not limited thereto. For example, the face images of all the players participating in the game may be displayed therein, or only the face image of a player who satisfies a predetermined condition (for example, a player who makes a raise) may be configured to be displayed. Furthermore, the face images may be configured to be continuously displayed on the second display unit, or the face images may be configured to be displayed only at predetermined timings (for example, at a time when a bet selection is made or a card is dealt) or only when a predetermined condition (for example, a condition that the amount of the pot exceeds a predetermined amount or a raise of an amount equal to or larger than a predetermined amount is made) is satisfied. 
         [0154]    In the embodiment, although the face image of a player selected by the player playing the game is displayed on the liquid crystal display  10  of the station  3  to which the selection operation is input, in the present invention, the face image of the selected player may be displayed on second display units of stations other than the station to which the selection operation is input. 
         [0155]    In the present invention, the positions in which the face images are displayed on the first display unit and the second display unit are not limited to those shown in the examples of  FIGS. 1 and 5 . 
         [0156]    Although a case where the game system  1  has two main displays  2  disposed back to back has been described in the embodiment, the game system according to the present invention is not limited thereto. 
         [0157]    Hereinafter, examples of game systems having configurations other than the configuration of the game system  1  will be described. 
         [0158]      FIG. 12  a perspective view showing the appearance of a game system according to another embodiment. 
         [0159]    As shown in  FIG. 12 , a game system  100  has one main display, and it is configured that all the players participating in the game play the game while viewing the same main display. 
         [0160]    As described above, the present invention can be applied to a game system having one main display. 
         [0161]    The game system according to an embodiment may not have a second display unit. 
         [0162]    Although a case where Hold&#39;em Poker is played as a game has been described in the above-described embodiments, the game performed by the game system is not limited to a specific game as long as the game is played by a plurality of players while a common first display unit is viewed.
