Description

  The present invention relates to a sand device, a deposit balance adjusting machine, a management server, and a game system, and can be applied to a game system including, for example, a sand device provided in association with a pachinko machine, a pachislot machine, or the like. .

  Sand devices provided in connection with pachinko machines, pachislot machines, etc., discharge game media such as game balls and game coins according to deposit processing, etc., and instruct game machines to discharge game media To do. As a depositing method for the sand device, there is a method of using a card such as a prepaid card or a membership card in addition to a depositing method by cash. Here, when the membership card is inserted into the sand device, the sand device and the game hall management server (the management server and the host controller are collectively called the management server) communicate to authenticate the member. .

  However, in the case of a sand device that uses a card, there is a possibility of fraudulent behavior such that when the player temporarily leaves for some reason, the card is removed from the sand device and the card is misused. In the case of a sand device using a card, there are many mechanical configurations such as a card transport mechanism and a card reading mechanism, and the occurrence frequency of abnormalities such as a card jam or a reading error is high.

  Therefore, a sanding device having a function (for example, accumulating a deposit balance and lending a ball from the accumulated balance) similar to the case of using a card without using a card is desired.

  By the way, there are various devices in the game hall, and some devices that handle money or game media having the same value as money already have fingerprint authentication to authenticate operators such as employees. Some have applied functions (see Patent Documents 1 to 3).

  The fingerprint authentication function is easy to apply to the sand apparatus because of its small reading configuration and the like, but authentication is OK even when fingerprint reading is forced by another person.

In consideration of such points, a face authentication function that gives the consciousness being imaged not only to the person to be authenticated but also to the surrounding persons is preferable (see Patent Documents 4 and 5).

  By the way, when a contact such as fingerprint authentication is a requirement and the reading range by imaging is narrow, the imaging environment hardly poses a problem. On the other hand, in the case of face authentication, the imaging area becomes large, and the influence of the imaging environment is great.

  In addition, the amusement hall has a lighting effect such as cocktail light, many players search for suitable platforms, and the influence of external light varies depending on the distance from the entrance and exit. It is a place where the environment changes drastically. In addition, the person to be imaged is a player who is sitting on a chair with a small backrest and is facing a gaming machine, and how to sit down (such as how to sit forward and lean back) also has a large effect on the captured image. . In other words, the game environment has poor imaging environment, imaging conditions, and the like, and when an existing face authentication method is applied as it is, even an authentication OK target person cannot be authenticated. In order to avoid such inconvenience, if the threshold for determination at the time of authentication is made small (if authentication OK is easy to be issued), there is a high possibility that the subject of authentication NG will be authenticated.

  Therefore, when imaging a face, a sand device, a deposit balance settlement machine, and a management device that can achieve sufficient authentication accuracy while applying the face authentication method by imaging at the same imaging distance as that of reference data Servers and gaming systems are desired.

Note that the window portion may not be provided in order to prevent shielding of infrared irradiation light or reflected light.

  FIG. 3 is a block diagram illustrating an electrical configuration of the sand apparatus 3 according to the embodiment. The sand device 3 includes, as an electrical processing configuration, a control unit 20, a communication unit 21, a remote control receiving unit 22, a bill processing unit 23, a coin processing unit 24, a warning lamp driver unit 25, an LED driver unit 26, and a display LCD driver unit. 27, a ten key interface unit (ten key IF unit) 28, a CCD camera unit 29, an infrared sensor unit SE, and the like.

  The control unit 20 includes, for example, a CPU, a ROM, a RAM, and the like, and governs overall control of the sand device 3. For example, the control unit 20 controls each unit so that the sand apparatus 3 performs operations as illustrated in flowcharts of FIGS. 7 to 9, 11, and 14 described later. The control unit 20 stores data necessary for the control operation. For example, payment balance data that has been deposited and not converted into a game medium is stored.

  In the case of this embodiment, the control unit 20 controls the sand device 3 and the sand device 3R on the right side (the left side when viewed from the player side) (hereinafter, “R” at the end of the symbol is the right sand device). A pair of face data for registration or authentication (face data of a stereo image) is processed by processing the imaging signals (face image signals) given from the CCD camera units 29 and 29R. The process of converting to is done. Face data obtained by processing the imaging signal of the CCD camera unit 29 (hereinafter referred to as an analog / digital converted imaging signal) is referred to as “right imaging face data”, and the imaging signal of the CCD camera unit 29R. The face data obtained by processing is referred to as “left captured face data”. In addition, an imaging signal that is a source for creating right imaging face data is referred to as a right imaging signal, and an imaging signal that is a source for generating left imaging face data is referred to as a left imaging signal.

  The control unit 20 includes a pair of reference grayscale data 20a and 20aR for the right imaging signal and the left imaging signal, and reference imaging distance data 20b indicating the imaging distance to the imaging target when the reference grayscale data 20a and 20aR are set. I remember it inside. When imaging the player's face, the control unit 20 receives imaging distance data to the player's face measured by the infrared sensor unit SE, as will be described later, and the imaging distance data and the reference imaging distance data are Using the comparison result and the reference grayscale data 20a and 20aR, the grayscale correction is performed on the right imaging signal and the left imaging signal from the CCD camera units 29 and 29R. The density correction function will be described in detail in the operation section.

  The reference grayscale data 20a, 20aR is set by a setting operator such as a manufacturer-related person or a game hall-related person when, for example, the sand apparatus 3, 3R is installed, and thereafter is fixedly held. As the reference grayscale data 20a, 20aR, for example, a person concerned is seated at the player's position in front of the player 2, and the lighting environment is set to a predetermined environment regardless of the island position of the gaming machine 2 by a portable lighting device. A setting operator designates a predetermined area from the right imaging signal and the left imaging signal captured by the CCD camera units 29 and 29R, and the right imaging signal and the left imaging signal in the area are used. For example, if the right imaging signal or the left imaging signal shows a machine number provided at the upper part of the gaming machine (pachinko machine or pachislot machine) at the opposite position, the right imaging signal or the left imaging signal A signal in a small area including the machine number at is set as the reference grayscale data 20a, 20aR.

  The reference imaging distance data 20b is obtained by measuring the imaging distance to the face of the setting operator to be imaged using the infrared sensor unit SE when setting the reference density data 20a and 20aR. Set in association with 20a, 20aR.

  In addition, although illustration is abbreviate | omitted for acquisition and setting of the above reference grayscale data 20a and 20aR, the sand apparatus 3 has a connection connector with the terminal for a setting which has a monitor part, and controls with a terminal. Signals can be exchanged with the unit 20. Note that signal transmission / reception via the communication unit 21 may be performed.

  Note that even if the lighting environment is set to the predetermined environment, the degree of achievement of the predetermined environment may vary depending on the time zone. Therefore, as the reference grayscale data 20a and 20aR, the grayscale correction described later can be easily performed for each time zone. You may make it prepare a separate thing. In addition, the control unit 20 has a statistical processing function for performing statistical processing on the right imaging signal and the left imaging signal from the CCD camera units 29 and 29R, and averages within a predetermined time obtained by the statistical processing function of the control unit 20. The converted right imaging signal and left imaging signal may be used as the reference grayscale data 20a.

  In the case of this embodiment, as described above, the face data of a pair of left and right stereo images is used for face authentication. A thin-type device having only an imaging function on the right side of the right-side gaming machine 2 so that a stereo image can be obtained even if there is no right-side sanding device, such as the side-by-side sand device of the right-side gaming machine 2 Hereinafter, it is referred to as an imaging-only sand device). This image-capturing sand device is also the same as the general sand device 3 in terms of the image capturing function for face authentication.

  The communication unit 21 performs communication with the gaming machine 2, the island unit controller 4, the management server 5, and the like under the control of the control unit 20. Although shown collectively in FIG. 3, the communication unit for gaming machines 2 is often separate from the communication units for other devices. The management server 5 employs a polling method in which the sand apparatus 3 is sequentially communicated with each other, and the communication unit 21 communicates with the management server 5 in response to such polling. Do. The deposit balance settlement machine 7 may be the target of the polling method from the management server 5 as with the sand device 3.

  The sand device 3 communicates with an adjacent sand device 3R (which may be an imaging-only sand device) 3R via the island unit controller 4.

  The remote control receiving unit 22 receives a remote control signal from a remote control transmitter (not shown) carried by the game hall employee via the remote control communication window 15 described above, and gives it to the control unit 20. is there.

  The banknote processing unit 23 directly controls a banknote transport configuration, a recognition configuration, a storage configuration, and the like (not shown), performs authenticity determination and denomination determination of the banknote inserted from the banknote insertion port 13 described above, Information on the inserted bill is given to the control unit 20. In addition, when it determines with what was inserted in the banknote insertion slot 13 is a fake banknote, the banknote process part 23 performs the process which discharges the determination paper from the banknote insertion slot 13. FIG.

  The coin processing unit 24 directly controls a coin conveyance configuration, a recognition configuration, a storage configuration, and the like (not shown), performs true / false determination and denomination determination of the coins inserted from the coin insertion port 14 described above, Information on the inserted coins is given to the control unit 20. Note that the coin processing unit 24 performs a process of discharging the false determination coin from the coin return port 18 when it is determined that the coin inserted into the coin insertion slot 14 is a fake coin. In addition, you may make it limit the coin which the said sand apparatus 3 can handle to a 500 yen coin. This makes it easy to determine the authenticity of coins and denominations.

  The warning lamp driver unit 25 drives the warning lamp 11 under the control of the control unit 20, and the LED driver unit 26 drives the status display LEDs 12a to 12c under the control of the control unit 20. .

  The display LCD driver unit 27 drives the display LCD 16 under the control of the control unit 20. The display LCD 16 displays, for example, deposit balance data that can be converted into game media, other data, and messages. The ten key interface unit 28 senses an operation on the ten key unit 17 and notifies the control unit 20 of an operation signal.

  The CCD camera unit 29 images the player's face through the CCD camera window 19 under the control of the control unit 20 and gives the image signal to the control unit 20. Although the configuration of the CCD camera unit 29 is not illustrated, the CCD camera unit 29 includes a monochrome CCD camera and an imaging direction adjusting mechanism that is provided with the CCD camera and swings (rotates) in the left-right direction.

  The infrared sensor unit SE irradiates infrared rays toward the player's face to be imaged at the time of imaging, and measures the distance based on the reflected light to reach the player's face to be imaged. The imaging distance is measured, and the measured imaging distance data is given to the control unit 20. In addition, what functions as a ranging means for measuring the imaging distance to the imaging target is not limited to the infrared sensor unit, and other optical ranging sensors (for example, a sensor using laser light) can be applied. Further, as a distance measuring method, in addition to the distance measurement based on the amount of the reflected light, a three-point survey using a measurement result by the infrared sensor unit SER of the right sand device 3R can be applied.

  The sand device 3 shown in FIGS. 2 and 3 does not have a game medium discharge function (ball lending function), and activates and controls the game medium discharge function (ball lending function) of the gaming machine 2. A game medium discharge function (ball lending function) may be provided.

  FIG. 4 is a block diagram illustrating an electrical configuration of the management server 5 according to the embodiment. 4, the management server 5 includes a control unit 30, a communication unit 31, a database access unit (DB access unit) 32, and the like.

  The control unit 30 includes, for example, a CPU, a ROM, a RAM, and the like, and governs overall control of the management server 5. For example, the control unit 30 controls each unit so that the management server 5 executes operations as illustrated in flowcharts of FIGS. 12, 13, 16, and 17 described later. The control unit 30 stores data necessary for the control operation.

Although shown collectively in FIG. 4, you may provide the some communication part used selectively by the communicating party. The communication unit 31 communicates with each sand apparatus 3 according to a polling method.

  The database access unit 32 accesses the database 6 under the control of the control unit 30, and writes and reads data.

  FIG. 5 is an explanatory diagram showing the configuration of the face database 6 a in the database 6. One record of the face database 6a includes fields (items) such as right imaged face data, left imaged face data, registration time data, deposit balance data, and sand history data.

  The right imaged face data is face characteristic data obtained by processing any face image data of the player of the gaming machine 2 corresponding to the sand device 3 or the face image data. In the left imaged face data, the sand device 3R on the right side of the sand device 3 that is the imaging source of the right imaged face data is the face image data of the player of the gaming machine 2 corresponding to the sand device 3 or its face image. This is facial feature data obtained by processing the data.

  Each record of the face database 6a is sorted by the right imaged face data. That is, it is sorted by the arrangement of “0” and “1” from the head of the right imaged face data. Unlike general face authentication, the face data in this embodiment is that of an unspecified person. Therefore, when collating face data, the range of face data used for collation from other information can hardly be narrowed, and the collation time is shortened to some extent by sorting.

  The registration time data is the time (including date and time information) when the record is formed. The settlement of the deposit balance in cash is allowed only on the day when the deposit balance is accumulated, for example. In this case, it is determined whether or not cash settlement may be performed based on the registration time data. Further, for example, the withdrawal balance data stored in the database 6 may be accepted only for a predetermined period (for example, one month) from the initial storage time (at the time of registration). It becomes.

  The deposit balance data is the amount of the deposit balance that can be converted into a game medium. When this deposit balance is converted into a game medium, registered face data (right imaged face data, left imaged face data) It is necessary to match the face data obtained by imaging at that time.

  Sand history data is a part that stores a part excluding face data together with a reception time when transmission data including face data arrives.

  The sand database 6b stores various data for each sand device 3 although illustration of the configuration is omitted. For example, data on the deposit amount and deposit time of cash deposit is stored. Further, for example, data indicating whether or not the gaming machine 2 corresponding to the sand device 3 is playing is stored. However, face data is not stored in the sand database 6b.

  FIG. 6 is a block diagram illustrating an electrical configuration of the deposit balance settlement machine 7 according to the embodiment. In FIG. 6, the deposit balance settlement machine 7 has a control unit 40, a communication unit 41, a bill processing unit 42, a coin processing unit 43, a warning lamp driver unit 44, a status LED driver unit 45, a key interface as an electrical processing configuration.

  The control unit 40 includes, for example, a CPU, a ROM, a RAM, and the like, and governs overall control of the deposit balance settlement machine 7. For example, the control unit 40 controls each unit so that the deposit balance adjusting machine 7 executes an operation as shown in a flowchart of FIG. The control unit 40 stores data necessary for the control operation.

  In the case of this embodiment, the control unit 40 processes the left and right imaging signals given from the CCD camera units 47L and 47R and converts them into right imaging face data or left imaging face data. The control unit 40 includes a pair of reference grayscale data 40a and 40aR for the right imaging signal and the left imaging signal, and reference imaging distance data 40b indicating an imaging distance to the imaging target when the reference grayscale data 40a and 40aR are set. Is stored internally. When imaging the player's face, the control unit 40 receives imaging distance data up to the player's face measured by the infrared sensor unit 48, as will be described later, and calculates the imaging distance data and the reference imaging distance data. Using the comparison result and the reference grayscale data 40a and 40aR, the grayscale correction is performed on the right imaging signal and the left imaging signal from the CCD camera units 47L and 47R.

  The communication unit 41 performs communication with the management server 5 under the control of the control unit 40. The management server 5 may also be a polling target for the deposit balance settlement machine 7 as in the sand device 3. In this case, the communication unit 41 communicates with the management server 5 in response to the polling. . Note that the communication unit 41 may communicate with the management server 5 without being polled.

  The banknote processing unit 42 directly controls a banknote conveyance configuration, a banknote storage configuration, and the like (not shown), and is instructed when it is necessary to discharge the banknote in refunding the deposit balance under the control of the control unit 40. The indicated number of banknotes of the denomination is discharged to a banknote outlet (not shown).

  The coin processing unit 43 directly controls a coin transport configuration and storage configuration (not shown), and is instructed when coins need to be discharged in the refund of the deposit balance under the control of the control unit 40. The designated number of coins is discharged to a coin discharge port (not shown).

  The warning lamp driver unit 44 drives a warning lamp (not shown) under the control of the control unit 40.

  The state LED driver unit 45 drives one or a plurality of state LEDs (not shown) under the control of the control unit 40. The player is prompted to sit in a chair (not shown) provided at the imaging position by lighting or blinking (or a combination thereof) of the status LED. The key interface unit 46 senses an operation on an unillustrated settlement key, a staff call key, and the like, and notifies the control unit 40 of an operation signal.

  The CCD camera units 47L and 47R take an image of a player seated in a chair provided at an imaging position under the control of the control unit 40, and give the image signal to the control unit 40. Here, the positional relationship between the chair provided at the imaging position in the deposit balance adjusting machine 7 and the CCD camera unit 47L is as follows: the chair in front of the gaming machine 2 and the CCD camera in the sand device 3 corresponding to the gaming machine 2 The positional relationship between the chair provided at the imaging position in the deposit balance settlement machine 7 and the CCD camera unit 47R corresponds to the chair in front of the gaming machine 2 and the gaming machine 2. This is similar to the relationship with the CCD camera unit 29R in the sand device 3R on the right side of the sand device 3 to be operated. Note that the CCD camera units 47L and 47R of the deposit balance settlement machine 7 do not have to be provided with a horizontal swing mechanism, unlike the CCD camera unit 29 of the sand apparatus 3, for example.

  The infrared sensor unit 48 irradiates infrared rays toward the player's face to be imaged at the time of imaging, and measures the distance based on the reflected light to reach the player's face that is the imaging object. The imaging distance is measured, and the measured imaging distance data is given to the control unit 40. In addition, what functions as a ranging means for measuring the imaging distance to the imaging target is not limited to the infrared sensor unit, and other optical ranging sensors (for example, a sensor using laser light) can be applied. In addition, as a distance measuring method, for example, an existing technique such as 3-point surveying or 5-point surveying can be applied.

  Since the detailed configurations of the gaming machine 2, the island unit controller 4, and the pager base station 8 are the same as those of the conventional one, description of the detailed configurations is omitted.

(A-2) Operation | movement of embodiment Next, characteristic operation | movement of the game system 1 of embodiment is demonstrated. This embodiment uses face authentication for accumulation and withdrawal of deposit balances, and in order to improve the authentication accuracy of face authentication, at the time of imaging, density correction is performed using imaging distance data to the imaging target and reference grayscale data. It is characterized by introducing functions.

  FIG. 7 is a flowchart illustrating an outline of a process branch from the standby state of the sand device according to the embodiment.

  In the standby state, the control unit 20 of the sand device 3 repeatedly monitors whether ball lending has been instructed, cash has been deposited, whether payment by face authentication has been instructed, or refund of the deposit balance has been instructed ( S100 to S103).

  When the ball lending key of the sand device 3 or the ball lending key of the gaming machine 2 that is paired with the sand device 3 is operated, the control unit 20 receives the deposit balance data stored therein. If the deposit balance data is 0, the process immediately returns to the standby state. If the deposit balance data is other than 0, the ball lending process is executed (S105), and the standby is performed. Return to state.

  In the ball lending process in S105, although detailed illustration of the process is omitted, the control unit 20 sends a predetermined number of game media to the game media cradle of the game machine 2 in cooperation with a game media ejection function (not shown). At the same time, the deposit balance data stored therein is reduced by one unit, and the display of the deposit balance on the display LCD 16 is also updated, and the management server 5 is notified of changes in the deposit balance data. At this time, the management server 5 receives the notification from the sand device 3, and the sand device 3 of the sand database 6 b storing data for each sand device 3 (or for each gaming machine 2) in the database 6. Update your deposit balance data.

  The notification (transmission) of various data from each sand device 3 to the management server 5 is executed at a timing when the management server 5 gives the transmission right to the sand device 3 by polling. Hereinafter, although polling is not mentioned one by one, similarly, data transmission from the sand device 3 to the management server 5 is executed at the polling timing.

  Further, the control unit 20 of the sand apparatus 3 stores the internal processing of the detailed processing when there is a payment notification from the banknote processing unit 23 and the coin processing unit 24, that is, when there is cash payment, although the detailed processing is omitted. The deposit balance data is increased by the deposit amount, the display of the deposit balance on the display LCD 16 is updated, the variation of the deposit balance data is notified to the management server 5 and the deposit balance data of the management server 5 is also updated (S106). And it returns to a standby state.

  The control unit 20 of the sand device 3 shifts to the refund process shown in FIG. 8 when an instruction to refund (accumulate) the deposit balance is made, and when the deposit using face authentication is instructed, the control unit 20 of FIG. The process proceeds to a deposit process using the face authentication shown in FIG.

  When a refund key provided in the numeric keypad portion 17 of the sand device 3 or a refund key provided in the gaming machine 2 corresponding to the sand device 3 is operated, in other words, the deposit balance is refunded. When instructed, as shown in FIG. 8, the control unit 20 of the sand device 3 first checks whether the deposit balance data is 0 (S150). If the deposit balance data is 0, Returning to the standby state shown in FIG.

  On the other hand, if the deposit balance data is other than 0, the control unit 20 of the sand apparatus 3 may turn on or blink the status display LEDs 12a to 12c (including the case where only one is lit or blink; the same applies hereinafter) or Then, a message is displayed on the display LCD 16 to notify the player that the image will be captured soon (S151), and an instruction for left imaging including the imaging time is given to the control unit 20R of the right sand device 3R (S152).

  The control unit 20 of the sand device 3 is omitted in FIG. 8, but the control unit 20R of the right sand device 3R receives a reception response to the left imaging instruction on the condition that it receives an infrared sensor unit SE. Then, the distance measuring process is instructed (S153), and the CCD camera unit 29 captures an image at the imaging time (S154), and the left imaging signal captured by the CCD camera unit 29R of the right sand device 3R is captured (S155). ). When there is no reception response to the left imaging signal, the left imaging instruction is retransmitted.

  Although omitted in FIG. 8, when the left imaging instruction is given, the control unit 20 </ b> R of the right sand device 3 </ b> R confirms that imaging is possible (if imaging is impossible) For example, when preparation or operation for right imaging is being performed (when the processing of S153 in FIG. 8 is started), a reception response is returned, and for the left imaging with respect to its own CCD camera unit 29R. Then, at the imaging time included in the left imaging instruction, the CCD camera unit 29R takes an image, and the obtained imaging signal (left imaging signal) is controlled by the instructed sand device 3 To the unit 20.

  Note that the standby direction in the CCD camera unit 29 of each sand device 3 is the direction in which the player of the sand device 3 is imaged (right imaged). Further, the player's orientation at the time of imaging is not questioned.

  Thereafter, the control unit 20 of the sand device 3 sets the reference grayscale data 20a and 20aR and the reference imaging distance data set for the right imaging signal obtained by the CCD camera unit 29 and the left imaging signal obtained by the CCD camera unit 29R. The density correction is performed using 20b (S156).

  FIG. 9 is a flowchart showing details of the density correction operation for the image signal in step S156.

  First, the control unit 20 compares the imaging distance data measured by the infrared sensor unit SE with the reference imaging distance data 20b, and the difference between the reference imaging distance data 20b and the imaging distance data (reference imaging distance data−imaging). Distance data) is obtained (S170).

  When the difference between the reference imaging distance data 20b and the imaging distance data is obtained, the control unit 20 responds to the difference based on the correction relationship between the predetermined imaging distance data difference and the luminance correction value. A luminance correction value is determined (S171), and the right imaging signal and the left imaging signal are corrected using the luminance correction value (S172).

  Here, FIG. 10 is an explanatory diagram illustrating a correction relationship between the difference between the imaging distance data and the luminance correction value. In FIG. 10, the horizontal axis is a coordinate axis with a difference from the reference imaging distance data 20b as a variable, and the difference when the imaging distance data is smaller than the reference imaging distance data 20b (reference imaging distance data−imaging distance data> 0) is a positive coordinate, and a difference when it is large (reference imaging distance data−imaging distance data <0) is a negative coordinate. On the other hand, the vertical axis is a coordinate axis with the brightness correction value as a variable. When the brightness value is increased (that is, correction for brightening), the positive coordinate is set, and when the brightness value is decreased (that is, correction for darkening). Use negative coordinates.

  In FIG. 10, generally, as the imaging distance increases, the amount of light captured by the CCD camera increases and the luminance value for each pixel increases. Therefore, when the imaging distance is smaller than the reference imaging distance data 20b, the luminance value is corrected to be large and the reference imaging is performed. A correction relationship was set in which the luminance value is corrected to be smaller when the imaging distance is larger than the distance data 20b. Thereby, the correction value of the luminance value for the right imaging signal and the left imaging signal can be determined according to the difference between the reference imaging distance data and the imaging distance data.

  Also, depending on how the player sits, height, physique, etc., the imaging distance from the CCD camera to the player's face varies, and the imaging environment and imaging conditions may vary, but depending on the difference in the imaging distance data By performing the shading correction processing, it is possible to correct as a state close to the imaging distance at the time of setting the reference grayscale data 20a and 20aR (that is, an imaging environment and imaging conditions equivalent to those at the time of setting). be able to.

  After the density correction processing for the right imaging signal and the left imaging signal according to the difference in the imaging distance data, the density correction using the reference density data 20a and 20aR is performed on the corrected right imaging signal and left imaging signal. You may do it. Thereby, it can correct | amend as a state closer to the reference | standard light / dark data 20a and 20aR, and can improve the precision of face authentication.

  Here, as an example of the density correction processing for the right imaging signal and the left imaging signal using the reference grayscale data 20a and 20aR, for example, the control unit 20 has an area corresponding to the reference grayscale data 20a in the right imaging signal (for example, A background region, a face region, a region near a feature point of a face or a region including a feature point, and the like, and the maximum luminance and the minimum luminance in the recognition region are detected. Then, the control unit 20 determines a correction function for the luminance in the right imaging signal based on the maximum luminance MAX and the minimum luminance MIN in the reference grayscale data 20a and the maximum luminance max and the minimum luminance min in the right imaging signal. There is a method of correcting the right imaging signal according to the correction function. The left imaging signal is also performed in the same manner as the density correction in the right imaging signal, using the reference density data 20aR.

  As a method of region recognition, for example, since the position information of the region corresponding to the reference grayscale data 20a, 20aR is fixed, the degree of coincidence with the region in the right imaging signal and the left imaging signal (for example, the corresponding position (The sum of squares of differences between pixel values is applied) and the degree of coincidence with other candidate regions shifted by several pixels (1 to 5 pixels) in the horizontal direction or the vertical direction from the position in units of pixels There is also a method for calculating a region candidate and recognizing a region candidate that is the most consistent (the value of the matching degree is the smallest) as a corresponding region.

  Further, as a method for determining the correction function, for example, it is desirable that the luminance in the right imaging signal and the left imaging signal matches the luminance in the reference grayscale data 20a and 20aR, and therefore, the minimum luminance min of the right imaging signal and the left imaging signal. The correction amount is MIN-min, the correction amount of the maximum luminance max is MAX-max, and the correction amount of the luminance y between the minimum luminance min and the maximum luminance max is that the luminance y is the minimum luminance min and the maximum luminance max. There is a method of grasping at what ratio the interval is apportioned and combining the correction amount MIN-min for the minimum luminance min and the correction amount MAX-max for the maximum luminance max by the apportionment ratio.

  Returning to FIG. 8, when the density correction operation is finished, the control unit 20 converts the right imaging signal and the left imaging signal into right imaging face data and left imaging face data, which are feature data, respectively (S157), The obtained right imaged face data and left imaged face data are temporarily buffered (S158). Any existing method can be applied as the compression method for converting the imaging signal into the face data.

  Note that the refund may be refused while the gaming machine 2 corresponding to the sand device 3 is playing. That is, when performing imaging, other processing is prohibited and the timing of imaging is clearly defined. Since the face data is information belonging to an individual, it is registered for the first time when accumulating and refunding, so that unnecessary registration is not performed. Although omitted in FIG. 8, when the imaging fails or when the area corresponding to the reference grayscale data cannot be recognized in the imaging signal, the display contents of the status display LEDs 12a to 12c and the display message of the display LCD 16 are displayed. The content is that re-imaging is performed, and imaging is performed again.

  When the control unit 20 of the sand device 3 acquires the transmission right, the control unit 20 includes at least data indicating that it is for storage, ID of the sand device 3, deposit balance data, right imaged face data, and left imaged face data. The transmission data for accumulation is transmitted to the management server 5 (S159), the end of imaging is displayed on the status display LEDs 12a to 12c or the display LCD 16 (S160), and the storage completion notification from the management server 5 is awaited (S161). Note that this transmission data for storage may be communicated by encrypted communication.

  Upon receiving the transmission data for accumulation, the control unit 30 of the management server 5 performs an accumulation operation of the deposit balance data in the face database 6a as shown in FIG. 12 (S200 to S203), and the deposit balance in the sand database 6b. The data is cleared to 0 (S204), and then the completion of accumulation is notified by polling transmission to the sand device 3 that has transmitted the transmission data for accumulation (S205).

  The accumulation operation of deposit balance data in the face database 6a by the control unit 30 of the management server 5 is, for example, as follows. The control unit 30 confirms whether a record of face data that matches the received face data (right imaged face data and left imaged face data) already exists (S200). If it exists, update the receipt balance data of the record to the original value plus the received balance data value, and add the history data related to this reception to the sand history data (S201). If a face data record matching the received face data does not exist in the face database 6a, a new record for the received face data is set (S202), and the received face data is set in the face data field. Insert the data, insert the current reception time by the timer built in the control unit 30 into the registration time data field, insert the received deposit balance data into the deposit balance data field, and insert into the sand history data field Inserts data relating to the current reception (S203). In setting a new record for the received fingerprint data, sorting based on face data is performed.

  The presence of a face data record that matches the received face data in the face database 6a is at a level at which it can be determined that both the right imaged face data and the left imaged face data match the stored data of the record. . First, the degree of match is determined using only the right imaged face data. If the degree of match is equal to or greater than the first threshold, the match determination is omitted for the left imaged face data, and the right image is captured. When the degree of match for the face data is smaller than the first threshold and greater than or equal to the second threshold, the match determination using the left captured face data is performed, and the average match determination time may be shortened. good. If the degree of match for the right imaged face data is smaller than the second threshold value, it is determined that they do not match.

  When receiving the storage completion notification from the management server 5, the control unit 20 of the sand device 3 clears the display of the deposit balance data (S162) and returns to the standby state of FIG.

  In the standby state, the control unit 20 of the sand device 3 is instructed to deposit using face authentication when the stored balance call key provided in the numeric keypad unit 17 of the sand device 3 is operated. In this case, as shown in FIG. 11, the player is notified that the image will be taken soon by a combination of lighting or blinking of the status display LEDs 12a to 12c, or by a message display on the display LCD 16 (S250). The left imaging instruction including the imaging time is given to the control unit 20R of the sand apparatus 3R (S251).

  The control unit 20 of the sand device 3 is omitted in FIG. 11, but on the condition that there is a reception response to the left imaging instruction from the control unit 20R of the right sand device 3R, the infrared sensor unit SE Then, the distance measuring process is instructed (S252), the CCD camera unit 29 captures an image at the imaging time (S253), and the left imaging signal captured by the CCD camera unit 29R of the right sand device 3R is captured (S254). ). When there is no reception response to the left imaging signal, the left imaging instruction is retransmitted.

  Thereafter, the control unit 20 of the sand apparatus 3 sets the reference imaging distance data 20b and the reference grayscale data 20a, which are set for the right imaging signal obtained by the CCD camera unit 29 and the left imaging signal obtained by the CCD camera unit 29R. The density correction is performed using 20aR (S255), and the right imaging signal and the left imaging signal subjected to the density correction are converted into right imaging face data and left imaging face data, which are feature data, respectively (S256). The obtained right imaged face data and left imaged face data are temporarily buffered (S257).

  In addition, while the gaming machine 2 corresponding to the sand device 3 is playing, the withdrawal by face authentication may be refused. That is, when performing imaging, other processing is prohibited and the timing of imaging is clearly defined.

  When the control unit 20 of the sand device 3 has acquired the transmission right, the transmission data for extraction including at least data indicating that it is for extraction, the ID of the sand device 3, right imaging face data, and left imaging face data. Is transmitted to the management server 5 (S258), the display for prompting face reading by the status display LEDs 12a to 12c is cleared (S259), and a reply such as a payment notice from the management server 5 is awaited (S260 to S263). It should be noted that communication of this outgoing transmission data may be performed by encrypted communication.

  When receiving the withdrawal transmission data, the control unit 30 of the management server 5 performs the withdrawal operation of the deposit balance data from the face database 6a as shown in FIG.

  The control unit 30 of the management server 5 checks whether or not a record of face data (right imaged face data and left imaged face data) that matches the received face data exists in the face database 6a (S300). The criterion for determining that a face data record that matches the received face data exists in the face database 6a is the same as the criterion for determining the balance accumulation described above.

  If it exists, it is determined whether or not the deposit balance data of the record is 0 (S301). If the deposit balance data is other than 0, the control unit 30 of the management server 5 forms a deposit notification including the deposit balance data of the record and returns it to the sand device 3 (S302), and receives the deposit balance data of the record. 0 is cleared, the contents of this time are added to the history data, and the deposit balance data for the sand device 3 in the sand database 6b is also updated (S303).

  On the other hand, if the deposit balance data in the face data record that matches the received face data is 0, the control unit 30 of the management server 5 uses the sand history data to extract the last sand device. (Hereinafter, this sand device is referred to as 3X) and the drawing time, and based on the stored contents of the sand database 6b for the sand device 3X that was drawn immediately before, the current of the sand device 3X It is determined whether or not the state is possibly illegal (S304).

  The player draws the accumulated balance in the sand device 3X, plays the game, moves to another sand device 3 position while leaving the balance in the sand device 3X without accumulating the balance again, and draws the accumulated drawer. When requested, if there is a possibility that the next player for the previous sand device 3X is diverting the balance left by the previous player, the control unit 30 of the management server 5 Can be recognized. Based on the contents stored in the face database 6a and the sand database 6b, after the withdrawal time in the previous sand device 3X, there is no cash deposit to the previous sand device 3X during the current withdrawal request from the sand device 3 By detecting that there is a deposit balance in the previous sand device 3X, the control unit 30 of the management server 5 can recognize the situation where there is a possibility of fraud.

  When the current state of the sand device 3X that has been pulled out immediately before is a state that may be illegal, the control unit 30 of the management server 5 forms and transmits an unusable notification to the sand device 3X. (S305), to the sand device 3 that is the transmission source of the currently received withdrawal transmission data, a deposit notice including the deposit balance data for the sand device 3X in the sand database 6b is formed and returned to the sand device 3 ( S306), the received balance data in the received face data record is cleared to 0, the current content is added to the history data, and the received balance data for the sand device 3 in the sand database 6b is also updated (S307). The pager terminal carried by the game hall employee in charge of the device 3X is likely to be fraudulent with respect to the sand device 3X. To knowledge (S308).

  It is preferable to include information that allows the control unit 20 of the sand apparatus 3 to distinguish between the deposit notification formed in step S306 and the regular deposit notification in step S302.

  If the deposit balance data is 0 and there is no possibility of fraud with respect to the previous sand device 3X, the control unit 30 of the management server 5 indicates that the accumulated balance is 0 in the currently received withdrawal transmission data. The data is transmitted to the sender sand device 3 (S309).

  If the control unit 30 of the management server 5 determines that no record of face data matching the received face data exists in the face database 6a, the face authentication failure count CNT for the sand device 3 is incremented by one. (S310), it is determined whether or not the number of times CNT has reached the upper limit (for example, 3 times) (S311). If the upper limit has not been reached, the re-reading notification of face data by re-reading is sent to the sand device 3. When the upper limit is reached, an authentication error notification is transmitted to the sand device 3 (S313).

  When the deposit notification from the management server 5 is given to the sand device 3 (S260), the control unit 20 of the sand device 3 increases the deposit balance data stored therein by the deposit amount, and displays the deposit balance on the display LCD 16. Are also updated (S264), and the process returns to the standby state shown in FIG. It should be noted that, depending on the combination of lighting or blinking of the status display LEDs 12a to 12c, it may be possible to distinguish between the receipt of the deposit notification in step S306 and the receipt of the deposit notification in step S302.

  When the notification that the balance is 0 is given from the management server 5 to the sand device 3 (S261), the control unit 20 of the sand device 3 displays the fact by the display LCD 16 and the status display LEDs 12a to 12c (S265). Returning to the standby state of FIG.

  When a notification of re-reading a face image by re-reading is given from the management server 5 to the sand device 3 (S262), the control unit 20 of the sand device 3 returns to step S250 described above and repeats the process.

  When an authentication error notification is given from the management server 5 to the sand device 3 (S263), the control unit 20 of the sand device 3 displays that fact by the display LCD 16 and the status display LEDs 12a to 12c (S266), and waits for FIG. Return to state.

  FIG. 14 is a flowchart showing an operation when the sand device 3X receives a use-disapproval notification (see S205 in FIG. 12) from the management server 5.

  When receiving the unusable notification from the management server 5, the control unit 20 of the sand device 3X forcibly clears the deposit balance data stored therein and the displayed deposit balance data to 0 (S350). The warning lamp 11 is turned on or blinked to issue a warning (S351). The warning may be given by a buzzer.

  FIG. 15 is a flowchart showing an operation at the time of settlement of the deposit balance settlement machine 7. The player can settle cash in the deposit balance accumulated in association with the face data. There is no need to limit the settlement date. However, in the following description, it will be assumed that cash can be settled only on the first day of deposit and accumulation.

  The control unit 40 of the deposit balance settlement machine 7 waits for an operation of the settlement key and the clerk call key, and starts the processing shown in FIG. 15 when the settlement key is operated. The explanation of the operation when operating the staff call key is omitted. It is assumed that the player is seated in a chair installed in front of the main body of the deposit balance settlement machine 7 and operates the settlement key.

  When the settlement key is operated and the settlement of the deposit balance is instructed, the control unit 40 of the deposit balance settlement machine 7 uses a combination of lighting or blinking of a status display LED (not shown) (or a display LCD). If the message is displayed, the player is notified that the image will be taken soon (S400), instructs the infrared sensor unit 48 to perform distance measurement processing (S401), and at a predetermined time thereafter, the CCD camera unit 47L and The image is captured by 47R (S402).

  Thereafter, the control unit 40 of the deposit balance adjusting machine 7 determines the right imaging signal obtained by the CCD camera unit 47L and the CCD camera unit 47R according to the difference between the imaging distance data from the infrared sensor unit 48 and the reference imaging distance data 48b. The left imaging signal obtained from the above is subjected to density correction (S403), the density-corrected right imaging signal and left imaging signal are converted into face data consisting of feature data (S404), and the obtained face data is temporarily converted. Buffering is performed (S405).

  The control unit 40 of the deposit balance settlement machine 7 includes at least data indicating that it is for settlement, the ID of the deposit balance settlement machine 7, right imaging face data, and left imaging face data when it acquires the transmission right. The settlement transmission data is transmitted to the management server 5 (S406), the end of imaging is notified to the player (S407), and an authentication notification reply from the management server 5 is awaited (S408 to S411). Note that the communication of the settlement transmission data may be performed by encrypted communication.

  When the settlement transmission data is given from the deposit balance settlement machine 7 to the management server 5, the control unit 30 of the management server 5 performs an operation using face data as shown in FIG.

  The control unit 30 of the management server 5 checks whether or not a face data record that matches the received face data exists in the face database 6a (S450).

  If it exists, it is determined whether or not the deposit balance data of the record is 0 (S451). If the deposit balance data is other than 0, the control unit 30 of the management server 5 determines whether or not the registration time data of the record is today (S452). If the registration time data is today, a positive authentication notification including the deposit balance data of the record is formed and transmitted to the deposit balance settlement machine 7 (S453), and a settlement completion reply from the deposit balance settlement machine 7 is awaited ( When the completion of payment is returned (S454), the corresponding record itself in the face database 6a is deleted (S455).

  When the deposit balance data is 0, the control unit 30 of the management server 5 forms a positive authentication notification to that effect and transmits it to the deposit balance settlement machine 7 (S456).

  When the deposit balance data is other than 0 and the registration time data is not today, the control unit 30 of the management server 5 forms a positive authentication notification to that effect and transmits it to the deposit balance settlement machine 7 (S457).

  In addition, when there is no face data record that matches the received face data in the face database 6a, the control unit 30 of the management server 5 forms a negative authentication notification and transmits it to the deposit balance settlement machine 7 (S458). ).

  When a positive authentication notification including the deposit balance data is given from the management server 5 to the deposit balance settlement machine 7 (S408), the control unit 40 of the deposit balance settlement machine 7 uses the banknote processing unit 42 and the coin processing unit 43 to deposit the balance. Is paid out (S412), payment completion is transmitted to the management server 5 (S413), and then returns to the standby state.

  When the management server 5 gives a positive authentication notification indicating that the deposit balance data is 0 to the deposit balance settlement machine 7 (S409), the control unit 40 of the deposit balance settlement apparatus 7 turns on a state display LED (not shown) or The fact that the deposit balance data is 0 is notified by the combination of blinking (notification time is a predetermined time of about 5 seconds; S414), and then returns to the standby state.

  Furthermore, when a positive authentication notification that the deposit balance data is other than 0 and the registration time is not today is given from the management server 5 to the deposit balance settlement machine 7 (S410), the control unit 40 of the deposit balance settlement machine 7 A combination of lighting or blinking of a status display LED (not shown) notifies that cash settlement other than the registration date cannot be made (the notification time is a predetermined time of about 5 seconds; S415), and then returns to the standby state.

  Furthermore, when a negative authentication notification is given from the management server 5 to the deposit balance settlement machine 7 (S411), the control unit 40 of the deposit balance settlement machine 7 determines the face data by a combination of lighting or blinking of a status display LED (not shown). (Notification time is a predetermined time of about 5 seconds; S416), and then returns to the standby state. Even at the time of payment, face data (right imaged face data and left imaged face data) may be retransmitted when authentication fails.

  As described above, the payment balance accumulated in association with the face data can be settled on the day when the face data is registered.

  FIG. 17 is a flowchart showing the organizing operation of the face database 6a executed by the control unit 30 of the management server 5.

  The control unit 30 of the management server 5 automatically starts the processing shown in FIG. 17 at a predetermined time after business hours (for example, 11:00 pm). If the management server 5 is provided with a man-machine interface such as a numeric keypad or a remote control receiver, the processing shown in FIG. 17 may be started in accordance with instructions from the game hall manager or employees. good.

  When the control unit 30 of the management server 5 starts the process shown in FIG. 17, the first record is set as a process target record (S500), and the first organizing process (S502 and S503) for all the records ends. (S501), it is determined whether or not the deposit balance data of the process target record is 0 (S502). If the receipt balance data of the process target record is 0, the record is deleted (S503), and if the receipt balance data of the process target record is other than 0, the process target record is immediately set to the next record. (S504), it returns to step S501 mentioned above.

  When the first organizing process for all the records ends, the control unit 30 of the management server 5 sets the first record (the first record remaining in the first organizing process) as the processing target record ( S505) After confirming that the second organizing process (S507 and S508) for all records has not been completed (S506), one month (this period) while referring to the registration time data and history data of the record to be processed It is determined whether or not this record has been accessed (S507). If the record to be processed has not been accessed for more than one month, the record is deleted (S508), and if the record to be processed is accessed when it is closer than January, the record to be processed is immediately The subsequent record is set (S509), and the process returns to step S506 described above.

  When the second organizing process for all records ends, the control unit 30 of the management server 5 ends the series of processes shown in FIG.

  As described above, records with a deposit balance of 0 and records with a deposit balance other than 0 but not accessed for more than one month can be organized.

(A-3) Effect of Embodiment According to the above embodiment, a method for storing a deposit balance in the management server in association with face data and retrieving the accumulated deposit balance to the sand device by face authentication is described. It can be applied to amusement halls with poor conditions.

  That is, based on the comparison result obtained by comparing the imaging distance to the player's face measured by the infrared sensor unit at the time of imaging and the reference imaging distance, which is the imaging distance when setting the reference grayscale data, Since the image signal is subjected to shading correction, even if the shooting distance is different due to differences in how the player sits, the shading correction can make the image signal related to the subject similar, and face authentication Can be executed appropriately.

  In the accumulation and retrieval of the deposit balance using the card, the card may be stolen when the player leaves the seat. However, the use of face authentication does not cause such a problem due to the theft. Further, in the embodiment, there is no card transport mechanism or the like, and accordingly, the reliability of the sand device can be improved. Furthermore, since the card conveyance configuration, the storage configuration access configuration, and the like can be replaced with the finger image capturing configuration, the sand device can be expected to be simple and inexpensive. In addition, the gaming system can be made cheaper due to the absence of a consumable card.

  In the case of a card system even when moving to another gaming machine or shifting to a checkout machine, it is necessary to carry the card and you will be worried about losing it, but use face data as in the embodiment In this case, since there is no portable article, there is no need to consider loss. The same applies to the case of leaving the game hall and withdrawing the deposit balance accumulated later.

  In the case of a card, it is difficult for the person who stole the card to prove that he / she has stolen the card, but with the deposit balance withdrawn based on the face data remaining, move to another gaming machine and deposit balance again The management server can recognize that the balance has been left in the previous gaming machine when trying to withdraw, and even if another person is playing there, the fraudulent behavior can be proved by historical data. it can.

  In the above embodiment, since the face data is sorted and stored in the face database, the authentication operation when the accumulated deposit balance is taken out can be expedited in this respect. Other systems that use face data for authentication also use authentication methods other than face authentication. For example, authentication is performed using face data after obtaining predetermined data (account data, card ID, etc.) from the card, and the face data on the database side used for collation is uniquely determined. On the other hand, in the case of this embodiment, the range of face data on the database side used for collation cannot be narrowed, and sorting of face data having a reasonable amount of data functions effectively.

(B) Other Embodiments In the description of the above-described embodiment, various modified embodiments have been mentioned.

  In the above-described embodiment, a gaming machine discharge configuration is provided in a gaming machine, and the sand device that instructs the gaming machine to discharge is shown. However, the present invention can be applied to a sand device having a gaming medium discharging configuration.

  Further, in the above-described embodiment, the regular imaging number when accumulating the deposit balance is shown as one, but the imaging may be executed twice or more. For example, the temporary registration may be performed in the management server at the first time, and the main registration may be performed when the second face data matches the first face data. Even withdrawing the accumulated deposit balance, the security may be improved by executing at least two readings.

  Further, in the above embodiment, the comparison between the stored face data of the face database and the read face data indicates that the determination result is either matched or non-matched. An appropriate determination result may be provided. For example, when an intermediate determination result is obtained, the management server instructs the sand device to read with a different finger when newly accumulating, and with the same finger when reaccumulating. The instruction content may be changed so as to instruct reading.

  Furthermore, in the above-described embodiment, the sand apparatus executes the conversion from the captured image to the face data. However, the captured image is directly given to the management server so that the management server performs the conversion to the face data. Also good. In this case, it is possible to reduce the processing load of the sand device. Further, the island unit controller 4 that relays communication may be provided with a conversion function from a captured image to face data. In this case, the processing load on the sand device and the management server can be reduced. The captured image itself may be used as face data.

  In the above embodiment, the accumulated deposit balance is read to lend the ball, and then the remaining deposit balance is allowed to be re-accumulated. good. Furthermore, since re-accumulation is premised, in the above embodiment, the record is not deleted from the face database even if the accumulated balance is read. However, when the accumulated balance is read, the record is deleted from the face database. Anyway. In this case, a record may be created as a new accumulation even at the time of re-accumulation.

  Furthermore, in the above-described embodiment, when the deposit balance is accumulated, transmission data including both face data and deposit balance data is transmitted from the sand device to the management server. The balance data may be divided into separate transmission data and transmitted at different timings. In this case, it does not matter which of face data and deposit balance data is transmitted first.

  In the above embodiment, the operation for accumulating the deposit balance is an operation of a refund key, and the balance after a part of the deposited cash is converted into a game medium can be accumulated. In addition to or instead of this, the balance immediately after the deposit, in other words, the deposit balance before being converted into the game medium may be stored in association with the face data. That is, the player can immediately accumulate the deposit balance in association with the face data immediately after depositing the cash, and can withdraw it from the accumulated deposit balance to the sand device.

  Furthermore, in the above embodiment, the withdrawal of the accumulated deposit balance shows that the entire amount is withdrawn. However, the player withdraws a part of the accumulated deposit balance by using the numeric keypad of the sand device. You may be able to.

  In the above embodiment, the balance data is directly exchanged as money data between the sand device and the management server. However, the money data is exchanged in another format, and the deposit balance data is stored in the management server. You may make it let it. For example, when there is a cash deposit, the deposit amount is given to the management server without corresponding to the face data and managed in association with the ID of the sand device. When there is a refund key, the face data and consumption data (game medium) For the first time, the face data may be stored in association with the face data and the deposit balance data obtained by the calculation. Further, the deposit balance data may be left in the face database even when the accumulated deposit balance data is withdrawn, and the consumption data may be given to the management server even during the accumulation. The movement of the “payment balance data” between the apparatuses in the claims includes such an indirect case.

  In the above embodiment, when the difference between the imaging distance data measured by the infrared sensor unit and the reference imaging distance data exceeds the threshold at the time of imaging, the player is notified that the sitting method is correct. An announcement or the like requesting to face the CCD camera may be notified.

  In the above-described embodiment, the operation guidance, warning, and the like are visually displayed and notified. However, instead of this, the operation guidance, warning, and the like may be notified audibly. Further, the warning notification may be performed using not only a single device such as a sand device or a deposit balance adjusting machine but also a group unit device such as an island unit. For example, you may make it alert | report by the light emission pattern etc. using the light emission structure which each apparatus has.

  In the above embodiment, the case where the CCD camera unit is swung in the horizontal direction has been described. However, the CCD camera unit may be rotated in the vertical direction or rotated. Further, soft zoom processing may be performed for either or both of the right imaging and the left imaging, and an imaging pattern using the zoom processing is selected from those having a good imaging environment. May be.

  In the above embodiment, the stereo face data is used, but one face data may be used.

  Furthermore, in the above embodiment, an example in which a monochrome CCD camera is used has been described. However, a color CCD camera may be used. In this case, reference color data is stored, and the reference color data is stored in the reference color data. This can be realized by selecting the most approximate imaging signal. Further, the shading and color tone of the imaging signal may be corrected using the reference shading data and the reference color tone data.

  In the above-described embodiment, only the face authentication is used for accumulating the deposit balance and withdrawing the accumulated deposit balance. However, other authentication methods that do not require carrying the article are used together. May be. For example, an authentication method by inputting a password or another individual authentication method may be used in combination. When password input is used together, the range of face data to be collated can be narrowed and the collation time can be shortened when the accumulated deposit balance is drawn.

  In the above-described embodiment, the sand device has a function of storing the deposit balance data in the management server in association with the face data, and has a function of withdrawing, but in addition to such a function, the deposit balance data is stored. A sand device having a function of storing in a card or reading from a card may be used as before. In the case of such a sand device, the player can use a numeric keypad or the like to select whether to store the deposit balance data in the management data or to record it on a card and discharge the card. Since the card ejection opportunities are reduced by the amount that can be stored in the management server, the effect of having the function of storing the deposit balance data corresponding to the face data (for example, reducing card jams) Even it can be demonstrated.

  In the above embodiment, the polling method is applied as the communication method between the management server and the sand device. However, other methods may be applied. For example, at the time of accumulation, the sand device may request transmission right, and the management server may perform contention arbitration and grant the transmission right to one of the sand devices.

  In the above embodiment, the case where the infrared sensor unit is applied as an example of the distance measuring unit has been described. However, a stereo camera (a CCD camera unit of the sand device and a CCD camera of the right sand device) is used as the distance measuring unit. May be. In this case, for example, the control unit obtains an imaging distance to the player's face (feature point) using an image based on the right imaging signal and the left imaging signal, and the imaging distance and left imaging based on the right imaging signal. You may make it obtain | require the distance to a player's face by three-point surveying the imaging distance based on a signal, and the distance between CCD cameras below. Regarding the distance measurement of the player's face in the image, the image size is fixed, and an image is taken so that a predetermined reference point (for example, a machine number) is displayed, and the reference point and the player's face (feature point) Is obtained by measuring the distance between the two points.
