Description

  According to the present invention, the mode of the apparatus main body is set according to the presence / absence of a user, between an execution mode for executing a process that has accepted an execution request, and a standby mode for stopping power supply to some functions of the apparatus main body. The present invention relates to an automatic processing device for switching.

  Conventionally, in an automatic processing device that executes processing according to a user's input operation, in order to reduce power consumption when there is no user, the operation mode of the device body is set as an execution mode according to the presence or absence of the user. Switching between standby modes is performed. The execution mode is a mode for executing processing according to a user's input operation, and the standby mode is a mode for stopping the power supply to some functions of the apparatus main body and waiting for the user to come. As this type of automatic processing apparatus, there are an automatic teller machine (hereinafter referred to as ATM) installed in a store or a convenience store of a financial institution, a vending machine that sells products, and the like.

  For example, Patent Literature 1 is configured to switch the operation mode of the apparatus main body from the standby mode to the execution mode when a user who approaches the apparatus is detected by a sensor. Moreover, patent document 2 is a structure which turns on the power supply of a transaction processing apparatus (it switches to an execution mode), if the user who enters this unattended store is detected with an entrance sensor about the transaction processing apparatus installed in the unattended store.

In addition, an apparatus has been proposed in which a user is imaged with a camera and the requested transaction is not executed when the user's eyes and mouth cannot be detected in the captured image (see Patent Document 3). In this patent document 3, a user wearing sunglasses, a user wearing a cover, a user wearing a hat deeply, etc. are estimated as suspicious persons, and by restricting transactions by this suspicious person, It prevents unauthorized transactions. Further, a configuration has been proposed in which the use of the device is not permitted until the user's face can be detected from the captured image of the camera after the user is detected by the sensor (see Patent Document 4).

  However, in the configuration of Patent Document 1, a person or an object passing through the detection range of the sensor is detected as a user, and the apparatus main body is switched from the standby mode to the execution mode. That is, although there is no user, the apparatus main body is wastefully switched from the standby mode to the execution mode. Therefore, there is a problem that the power consumption of the apparatus main body cannot be sufficiently suppressed. In addition, there is a risk that an increase in the number of switching between the execution mode and the standby mode induces a failure of the apparatus body and shortens the life of the apparatus.

  In Patent Document 2, it is assumed that all users who enter the store are users of the device. For this reason, when the store where the device is installed is a convenience store or the like, there are users who enter the store for purposes other than the use of this device. Switching between and is performed wastefully. Therefore, the power consumption of the apparatus main body cannot be sufficiently suppressed, and there is a risk of shortening the life of the apparatus.

  As described above, in the conventional automatic processing apparatus that executes the process according to the user's input operation, it is not possible to suppress the power consumption or extend the life.

  Patent Documents 3 and 4 are configurations for the purpose of improving security, and a configuration for suppressing power consumption and extending the life is not particularly proposed.

  An object of the present invention is to provide an automatic processing apparatus capable of sufficiently suppressing power consumption of the apparatus main body and extending the life of the apparatus main body.

  In order to solve the above problems and achieve the object, the present invention has the following configuration.

The execution request receiving means receives an input operation related to a process execution request for the apparatus main body. Further, the mode switching means stops the apparatus main body mode, the execution mode in which the execution request accepting means accepts the execution request, and the power supply to some functions of the apparatus main body are stopped to wait for the user. Switch between standby mode. Further, the object detection means detects the presence or absence of an object in front of the apparatus main body. When the object detecting means detects an object located in front of the apparatus main body, the imaging means waits for a predetermined waiting time to elapse, and even after the waiting time elapses, the object detecting means is located in front of the apparatus main body. If this is detected, imaging in front of the apparatus main body is started. Then, the face orientation detection unit captures a captured image in front of the apparatus main body imaged by the imaging unit, and detects whether a human face is captured in the captured image. Further, the face direction detecting means detects whether or not the face of the person is facing the front of the apparatus main body if the face of the person is captured in the captured image. Then, on condition that the face direction detecting means detects a person whose face is facing the front of the apparatus main body, the mode switching control means sets the mode of the apparatus main body to the execution mode with respect to the mode switching means. Instruct to switch.

  Usually, a person turns his / her face in a direction according to his / her purpose. For this reason, there is a high possibility that the face of the user approaching the apparatus to use the apparatus main body is facing the front of the apparatus main body. On the other hand, there is a high possibility that the face of a passerby who does not use the apparatus main body is not in front of the apparatus main body but in the direction of his / her own passage. If the face of the person imaged in the captured image in front of the apparatus main body imaged by the image pickup means is facing the front of the apparatus main body, that is, the person uses the apparatus main body. When the possibility of being a user approaching the apparatus is very high, the mode switching unit is instructed to switch the mode of the apparatus main body to the execution mode. On the other hand, the mode switching control means is configured so that the face of the person imaged in the captured image in front of the apparatus main body imaged by the imaging means is not directed to the front of the apparatus main body, that is, the person does not use the apparatus main body. When there is a high possibility that the user is a person, the mode switching means is not instructed to switch the mode of the apparatus main body to the execution mode. Therefore, it is possible to prevent the apparatus main body from being switched wastefully from the standby mode to the execution mode, the power consumption of the apparatus main body can be sufficiently suppressed, and the life of the apparatus main body can be extended.

In addition, a display control means for displaying a guidance screen for guiding an input operation on the apparatus main body on a display is provided, and when the face direction detecting means detects a person whose face is facing the front of the apparatus main body, the display control means It is good also as a structure which starts the display of the guidance screen in the said indicator. In this case, the mode switching control unit detects the person whose face is facing the front of the apparatus main body, and further, after the execution request receiving unit receives the execution request, the mode switching control unit It is preferable that the switching unit is instructed to switch the mode of the apparatus main body to the execution mode. As a result, the mode of the apparatus main body is not switched to the execution mode even when the face of a passerby passing around the apparatus temporarily faces the front of the apparatus main body.

  Further, when the mode switching unit switches from the standby mode to the execution mode, the execution request receiving unit continues to stop power supply to functions that are not involved in the execution of the processing for which the execution request has been received. The power consumption of the apparatus main body can be further suppressed.

  Further, an object detection means for detecting the presence or absence of an object in front of the apparatus main body may be provided, and when the object detection means detects an object located in front of the apparatus main body, the imaging means may start imaging in front of the apparatus main body. . In this way, useless processing (processing for a captured image in which a person is not captured) in the face orientation detection unit can be suppressed, and power consumption of the apparatus main body can be further suppressed.

  Further, the mode switching control means sets the mode of the apparatus main body to the mode switching means when the object detecting means does not detect an object located in front of the apparatus main body for a predetermined period of time. It is good also as a structure which instruct | indicates switching to the said standby mode, and when the process which the said execution request reception means received the execution request is completed, switching the mode of an apparatus main body to the said standby mode with respect to the said mode switching means. It may be configured to instruct.

  In this way, the apparatus main body can be shifted from the execution mode to the standby mode at an appropriate timing.

  According to the present invention, the power consumption of the apparatus main body can be sufficiently suppressed, and the life of the apparatus main body can be extended.

  Hereinafter, an automatic teller machine (hereinafter referred to as ATM) which is an embodiment of the present invention will be described in detail.

  FIG. 1 is a schematic diagram showing the appearance of the ATM, and FIG. 2 is a block diagram showing the configuration of the main part of the ATM.

The main control unit 2 controls the operation of each unit.

  The display / operation unit 3 includes a display 3a provided on the front surface of the main body and a touch panel 3b attached on the screen of the display 3a. The display / operation unit 3 displays an operation guidance screen for the user on the display 3a. Further, the display / operation unit 3 receives a user's input operation relating to a personal identification number and transaction content (transaction type, deposit / withdrawal amount, etc.) by detecting the pressed position of the touch panel 3b. The display / operation unit 3 may include a biometric information reading unit that reads biometric information of a user (fingerprint, finger vein, palm print, etc.).

  The banknote processing unit 4 transports banknotes along a banknote transport path formed between a banknote deposit / withdrawal port 4a provided on the front face of the main body and a denomination-type banknote cartridge (not shown) housed inside the main body. It has a bill conveyance part (not shown). Moreover, the banknote processing unit 4 has the banknote discrimination part (not shown) which discriminates a money type and authenticity for every banknote conveyed along the banknote conveyance path. The coin processing unit 5 transports coins along a coin transport path formed between a coin deposit / withdrawal port 5a provided on the front face of the main body and a denomination type coin cartridge (not shown) housed inside the main body. A coin transport unit (not shown). Moreover, the coin processing unit 5 has a coin discriminating section (not shown) for discriminating the denomination and authenticity for each coin transported along the coin transport path.

  The card / detail processing unit 6 takes in a card inserted into a card insertion slot 6a provided on the front of the main body, reads card information (financial institution number, store number, account number, etc.) recorded on the card, Rewrite card information. The card / detail processing unit 6 may be configured to process a magnetic card, may be configured to process an IC card, or may be configured to process both cards (magnetic card and IC card). It may be. Further, the card / detail processing unit 6 has a printing unit (not shown) for printing transaction contents on the specification. The card / specification processing unit 6 discharges the specification printed with the transaction contents to the specification discharge port 6b provided on the front face of the main body.

  The passbook processing unit 7 has a printing unit (not shown) that takes in a passbook inserted into a passbook insertion slot 7a provided on the front of the main body and prints a transaction history for the passbook. Further, the passbook processing unit 7 is recorded on a page turning mechanism for turning over a page of the taken passbook, a bar code reader for reading a bar code indicating a page number printed on the passbook, and a magnetic stripe attached to the passbook. It also has a magnetic head or the like that reads the bankbook information (financial institution number, store number, account number, etc.). The communication unit 8 controls data communication with a host device (not shown) installed in the center.

  The user detection unit 10 detects a user of the ATM1 main body. FIG. 3 is a block diagram showing the configuration of the main part of this user detection unit. The user detection unit 10 includes a control unit 11, an object detection unit 12, an imaging unit 13, an image processing unit 14, and a power supply unit 15. The control unit 11 controls the operation of each part of the user detection unit 10 main body and controls input / output with the main control unit 2. The object detection unit 12 has a sensor 12a attached to the front panel of the ATM1 main body. The sensor 12a is, for example, a reflection type optical sensor or an ultrasonic sensor. As shown in FIGS. 4A and 4B, the detection area of the sensor 12a is within a range of several meters (2 to 3 m) in front of the ATM 1 body, and several tens of centimeters (50 to 70 cm) from the floor. It is height.

  The imaging unit 13 has a camera 13a attached to the top plate of the ATM1 body. The camera 13a is adjusted so that the imaging area is in front of the ATM1 main body. As shown in FIGS. 4A and 4B, the camera 13a is focused on a position closer to the front of the ATM1 main body than the sensor 12a (a position about 1 m in front of the main body front). The camera 13a is preferably provided with a swing mechanism so that the direction of the imaging area can be adjusted according to the installation environment of the ATM1 main body, the mounting position of the ATM1 main body on the top plate, and the like. Further, the camera 13a may be built in the ATM1 main body and configured to image the front front of the ATM1 main body through the front panel of the ATM1 main body.

  The image processing unit 14 processes a captured image of the camera 13a and detects whether or not a person's face captured in the captured image is facing the ATM1 main body front. Details of the image processing in the image processing unit 14 will be described later. The power supply unit 15 includes a power supply circuit that supplies operating power to each unit of the user detection unit 10.

  In addition, the display / operation unit 3, the bill processing unit 4, the coin processing unit 5, the card / detail processing unit 6, the passbook processing unit 7, and the communication unit 8 described above also supply operating power to each part in the unit. It has a power supply circuit. The main control unit 2 controls, for each unit, supply / stop of primary power to the power circuit of the unit. For example, the main control unit 2 performs open / close control of a switch for switching supply / stop of the primary power supply to the power supply circuit of the unit for each unit. Each unit starts its operation when primary power supply is started by the main control unit 2.

  The ATM 1 switches the operation mode of the main body between an execution mode and a standby mode according to the presence or absence of a user. The execution mode is a mode for processing a deposit / withdrawal transaction requested by the user. In standby mode, when there is no user, the supply of primary power to some units is stopped.In other words, the primary power supply is supplied only to a specific unit, and there is a user who makes transactions. It is a waiting mode. ATM1 suppresses the power consumption of the ATM1 main body and extends the life of the ATM1 main body by setting the operation mode of the main body to the standby mode when there is no user.

  The operation of this ATM 1 will be described below.

  FIG. 5 is a flowchart showing the operation of ATM. ATM1 sets the operation mode to the standby mode when there is no user. In this standby mode, the main control unit 2 and the user detection unit 10 are supplied with operating power and are operating. On the other hand, in the other units, the primary power supply is stopped by the main control unit 2, and the operating power is not supplied.

  The ATM 1 waits for the user detection unit 10 to detect the user (s1). Details of the process in which the user detection unit 10 detects the user will be described later. When the user detection unit 10 detects the user, the ATM 1 starts supplying primary power to the display / operation unit 3 (s2). As a result, the display / operation unit 3 starts operating. At the time of s2, supply of primary power to the banknote processing unit 4, the coin processing unit 5, and the passbook processing unit 7 is not started.

  If the card is received before the input operation for selecting the transaction type is performed on the display / operation unit 3, if it is ATM1 that determines that the withdrawal transaction is selected, the card / detail processing is performed at the time of this s2. The supply of primary power to the unit 6 may be started. In other words, if ATM1 does not accept a card before an input operation for selecting a transaction type is performed on display / operation unit 3, supply of primary power to card / detail processing unit 6 is not started at time s2. What is necessary is just composition.

  In ATM1, the display / operation unit 3 from which the supply of operating power is started displays a transaction type selection screen on the display 3a (see FIG. 6). The ATM 1 waits until the user inputs a transaction type selection (s3) or the user detection unit 10 detects that the user has left (s4). In s3, if the card is received before the input operation for selecting the transaction type in the display / operation unit 3 is performed, if the ATM 1 determines that the withdrawal transaction is selected, the transaction type is set in the display / operation unit 3. Even if the input operation to select is not performed, the selection input of transaction classification (withdrawal transaction) is received by reception of a card. In s4, when the user detected by the object detection unit 12 is no longer detected, it is determined that the user has left. When it is detected that the user has left, the ATM 1 instructs the unit to stop the operation for each unit that has started supplying the primary power in s2, and stops the supply of the primary power after the shutdown process of the unit is completed ( s5) This process is terminated. In s5, if supply of primary power to the card / detail processing unit 6 is started in s2, supply of primary power to the card / detail processing unit 6 is also stopped. On the other hand, regarding the main control unit 2 and the user detection unit 10, the power supply is continued and the operation is not stopped.

  Thus, when the user detected by the user detection unit 10 does not make a transaction at the ATM 1, the supply of primary power to the banknote processing unit 4, the coin processing unit 5, and the passbook processing unit 7 is not started. Therefore, wasteful power consumption when the user detected by the user detection unit 10 does not conduct a transaction at ATM 1 can be suppressed. Further, the banknote processing unit 4, the coin processing unit 5, and the passbook processing unit 7 are not wastefully driven / stopped.

  When the ATM 1 accepts the transaction type selection input by the user in s3, the ATM 1 determines a unit involved in the transaction processing of the selected transaction type (s6). Specifically, a unit that does not perform any processing regardless of the transaction content of the selected transaction type is determined as a unit that does not participate in the transaction processing, and some processing is performed regardless of the transaction content of the selected transaction type. A unit that may or may not perform processing depending on the unit or transaction content is determined as a unit involved in transaction processing. For example, if the selected transaction type is bankbook entry, it is determined that the banknote processing unit 4, the coin processing unit 5, and the card / detail processing unit 6 are not involved in the transaction, and the bankbook processing unit 7 is Determine that the unit is involved in the transaction. If it is a transfer transaction, the bankbook processing unit 7 is determined to be a unit not involved in the transaction, and the banknote processing unit 4, the coin processing unit 5, and the card / detail processing unit 6 are units involved in the transaction. Judge.

  In the case of a transfer transaction, one of banknotes or coins may not be handled in actual transaction processing, but the banknote processing unit 4 and the coin processing unit 5 are determined to be units involved in the transaction processing. .

  ATM1 starts supply of the primary power supply with respect to the unit judged to be involved in the transaction processing of the selected transaction type (s7). Thereby, the unit that may be involved in the transaction processing of the transaction type selected in s3 starts the operation. That is, ATM1 is in a state in which transaction processing of the transaction type selected in s3 can be performed. This state corresponds to the execution mode referred to in the present invention. ATM1 processes the transaction requested by the user (s8). In s8, a card, a passbook, and the like necessary for the transaction are accepted, and an input operation such as a deposit amount and a withdrawal amount is accepted. Since transaction processing in ATM1 is well known, detailed description is omitted here.

  When the transaction processing of the transaction type requested by the user is completed, the ATM 1 determines whether or not the user continues to perform the transaction (s9). Details of the processing according to s9 will be described later. If the ATM 1 determines that the user continues to conduct the transaction in s9, the display / operation unit 3 displays a transaction type selection screen on the display 3a (s10), and returns to s3. On the other hand, if it is determined that the user does not continue the transaction in s9, ATM1 instructs the unit to stop the operation for each unit that has started supplying the primary power in s2 and s7, and after the shutdown process is completed for each unit The supply of primary power is stopped (s11), and this process is terminated. In s11, the power supply to the main control unit 2 and the user detection unit 10 is not stopped and the operation is continued. Thereby, ATM1 returns to standby mode.

  As described above, since the ATM 1 does not supply the primary power supply to the unit that is not involved in the transaction processing of the transaction type selected in s6, wasteful power consumption in the main body of the ATM 1 can be suppressed. When the determination is made according to s9 and the user makes a new transaction in succession to the previous transaction, it is configured not to return to the standby mode from the execution mode. There is no.

  In the above description, it is assumed that the main control unit 2 and the user detection unit 10 are operating when the ATM 1 is in the standby mode. However, the main control unit 2 may be configured to stop power supply. . In this case, the user detection unit 10 may be configured to control power supply / stop for the main control unit 2 and start power supply to the main control unit 2 when a user is detected. Further, the user detection unit 10 may be configured to supply / stop the primary power with a power switch or the like. As for the other units, as in the above-described embodiment, the main control unit 2 may control the supply / stop of the primary power supply, or the user detection unit 10 controls the supply / stop of the primary power supply. May be.

  Next, the user detection process related to s1 described above will be described in detail. FIG. 7 is a flowchart showing user detection processing in the user detection unit. In the user detection unit 10, the object detection unit 12 detects the presence or absence of an object located within the detection area of the sensor 12a. When the user detection unit 10 detects an object located within the detection area of the sensor 12a (s21), the user detection unit 10 waits for a predetermined first time (for example, about several hundred ms to 1s) to pass (s22), and then again. Then, it is detected whether or not the object is located within the detection area of the sensor 12a (s23).

  The processes related to s22 and s23 are processes provided to prevent the following processes after s24 from being executed on an object that has temporarily entered the detection area of the sensor 12a. If the object located in the detection area of the sensor 12a is not detected in s23, that is, if the object detected in s21 is an object that has temporarily entered the detection area, the user detection unit 10 returns to s21. .

  When the user detection unit 10 detects an object located within the detection area of the sensor 12a in s23, the user detection unit 10 activates the imaging unit 13 and starts imaging the front surface of the ATM1 main body with the camera 13a (s24). The image processing unit 14 captures an image captured by the camera 13a, and determines whether the object captured in the captured image (the object located in the detection area of the sensor 12a detected by the object detection unit 12) is a human being. (S25). In s25, the outline of the object being imaged is detected, and it is determined from the outline whether the person is a person. For example, a difference image between a background image when no object is located in the imaging area of the camera 13a and a captured image captured by the camera 13a this time is generated, and the contour of the imaged object is detected. Then, pattern matching is performed on the detected contour of the object such as a human face, torso, hand, and foot to determine whether the object being imaged is a human being.

  If the user detection unit 10 determines that the object being imaged is not a human being, whether or not the object detection unit 12 can no longer detect an object located within the detection area of the sensor 12a (s26). (E.g., about 1 s to 2 s) elapses (s27). When the object detection unit 12 no longer detects an object located within the detection area of the sensor 12a, the user detection unit 10 stops the imaging unit 13 (s28) and returns to s21. On the other hand, if it is determined in s27 that the predetermined second time has elapsed, the process returns to s25 and the above-described processing is repeated.

  By performing the processing of s26 to s28, it is possible to prevent the imaging unit 13 from being repeatedly activated / stopped by a non-human object detected at this time, and approach the ATM 1 after detecting the non-human object. It is possible to detect properly humans.

  If the user detection unit 10 determines that a person is imaged in s25, the user detection unit 10 determines whether the face is facing the ATM1 main body front (s29). Details of the processing according to s29 will be described later. Normally, a user who uses ATM1 walks toward ATM1, and his face is facing the front of the ATM1 main body. On the other hand, a person (passerby) who passes around the ATM 1 turns his / her face in the direction of his / her walking, and the face does not face the front of the ATM 1 main body. If the user detection unit 10 determines in s29 that the face is not facing the ATM1 main body front, whether the object located in the detection area of the sensor 12a is no longer detected by the object detection unit 12 (s30) is determined in advance. It waits for the elapse of a third time (for example, about several hundred ms to 1 s) (s31). When the object detection unit 12 no longer detects an object located within the detection area of the sensor 12a, the user detection unit 10 stops the imaging unit 13 (s32) and returns to s21. On the other hand, if the user detection unit 10 determines that the third time predetermined in s31 has elapsed, the user detection unit 10 performs the above-described processing after s25.

  If the user detection unit 10 determines in s29 that the face is facing the front of the ATM 1 main body, the user detection unit 10 waits for a predetermined fourth time (for example, several 100 ms) to elapse (s33). Then, it is determined again whether the face of the person imaged in the captured image of the camera 13a is facing the ATM1 main body front (s34). The process related to s34 is the same as the process related to s29. If the user detection unit 10 determines in s34 that the face is not facing the ATM1 main body front, the process after s30 described above is performed. As a result, when a passerby who passes around the ATM1 performs the process related to s29, the passerby is detected as a user even if the face happens to face the front of the ATM1 main body. Can be prevented.

  Note that s32 and s33 are provided in order to more reliably prevent detection of a passerby as a user, and in particular, s33 and s34 may not be provided.

  If the user detection unit 10 determines in s34 that the face is facing the front of the ATM 1 main body, the user detection unit 10 notifies the main control unit 2 of the presence of the user (s35) and ends this process. The main control unit 2 determines that the user of the ATM 1 has come based on the user detection notification from the user detection unit 10, and executes the above-described processing related to s2.

  Thus, when the user detection unit 10 detects an object located in the detection region of the sensor 12a of the object detection unit 12, the user detection unit 10 does not detect the object as a user, but the object is a human. And whether or not the user is a user on the condition that the human face is facing the front of the ATM1 main body. Accordingly, it is possible to sufficiently prevent an object that has passed around the ATM1 main body or a passerby from being erroneously detected as a user of the ATM1 main body. Therefore, it is possible to prevent the ATM1 body from switching from the standby mode to the execution mode by an object that has passed around the ATM1 body or a passerby, sufficiently reducing the power consumption of the ATM1 body, and extending the life of the ATM1 body. I can plan.

  Next, a process of determining the face orientation (face orientation determination process) according to s29 and s34 will be described. In this face orientation determination process, the orientation of the face is determined based on face parts such as the forehead, eyes, nose, and mouth existing on the human face. Specifically, with reference to positions (gaze points) corresponding to face parts such as the forehead, eyes, nose, mouth, etc. present in the human face image captured in the image captured by the camera 13a of the imaging unit 13, A plurality of preset feature points are extracted. Then, the orientation of the face is determined from the gazing point and the arrangement of the feature points.

  In the gazing point and feature point setting process, first, a human face image captured in the captured image of the camera 13a is detected. The detection of the face image may be performed, for example, by template matching using a reference template corresponding to the contour of the face, or may be performed by another method. Next, a face part in the detected face image is detected. This facial component may be detected by detecting the facial components such as the forehead, eyes, nose, and mouth by pattern matching or the like. After the detection of the facial part is completed, the image is converted into a gray scale or the gradation is corrected, and the gazing point and the feature point are set based on the detected position of the facial part.

  Here, a case where a gazing point is set for four face parts of the forehead, the left and right eyes, and the mouth will be described as an example. FIG. 8 shows a face image taken from the front. As shown in FIG. 8, the gaze points U1, L1, R1, and M1 are set at the forehead center, the left eye center, the right eye center, and the lip center (the forehead center is the gaze point U1, the left eye center) Is the gazing point L1, the center of the right eye is the gazing point R1, and the center of the lips is the gazing point M1.) The feature points are set as the distance from the point of interest. The feature points (a1 to z1, α1 to δ1) are set at a plurality of positions on the face including the left and right eyebrows, eyes, mouth, nose, cheeks, chin, and the like for the center line L1 of the face image. The position for setting the feature point is set in advance.

  Further, in the case of a face image obtained by imaging the user's profile, the point of gaze and feature points are set as shown in FIG. In FIG. 9, the reference numerals and the reference numerals assigned to the feature points correspond to those in FIG. 8. Specifically, the symbols (U, L, R, M, a to z, α to δ) indicating the gazing point and the feature points are the same, and the number consecutive to the symbols is “2”. In addition, for a face image obtained by imaging the user's face from an oblique direction, a gazing point and a feature point are set as shown in FIG. Also in FIG. 10, the reference points and the reference numerals assigned to the feature points correspond to FIG. 8 and FIG. 9. Specifically, the symbols (U, L, R, M, a to z, α to δ) indicating the gazing point and the feature points are the same, and the number consecutive to the symbols is “3”.

  Since the human face is substantially bilaterally symmetric, the orientation of the face can be determined from the set gazing point and feature points. Specifically, attention points and feature points that cannot be set depending on the orientation of the face are stored in advance. Then, the orientation of the face relative to the camera 13a is determined based on the gazing point or feature point that could not be set for the captured image and the gazing point or feature point that could not be set depending on the stored face orientation. That is, it is determined whether the face is taken from the front, or the face is taken from the right or left direction. Further, since the angle difference between the imaging direction of the camera 13a and the ATM1 main body front direction is known, the face orientation relative to the ATM1 main body front can be detected from the face orientation relative to the camera 13a.

  In addition, in the case of a captured image captured from an oblique direction as shown in FIG. 10, the gaze point and the feature point can be set as in the captured image captured from the front, but the right side of the center line L1 of the face image, Alternatively, the interval between the feature points set on one side on the left side is closer than the interval set on the other side. From this, the direction in which the face is facing can be determined by comparing the interval between the feature points on the left and right. For example, in FIG. 10, in the eyebrows, the distance between the left and right feature points a3 to c3 and e3 to g3 is shorter for a3 to c3 and longer for e3 to g3. Can be determined to be facing right.

  In addition, the interval between the gazing point and the feature point of the reference face image is stored in advance and compared with the interval between the gazing point and the feature point of the acquired face image. It can also be determined whether there is any.

  Furthermore, when the user imaged by the camera 13a is wearing sunglasses or wearing a mask, a part of this user's facial part is hidden, so the point of gaze and features near the hidden facial part The point cannot be set. FIG. 11 is a face image obtained by imaging a user wearing sunglasses from the front, and FIG. 12 is a face image obtained by imaging the user wearing a mask from the front. However, in the case of a face image that does not capture the user from the front, as described above, a part of the face image is continuously hidden, but when wearing sunglasses or wearing a mask, Only the facial parts are hidden. Therefore, when wearing sunglasses or wearing a mask, it is not possible to determine the orientation of the face using only the set gazing point. However, the orientation of the face can be determined by comparing the interval between the feature points set for the face component that is not hidden between the left and right sides of the face. For example, in the case of wearing sunglasses as shown in FIG. 11, the point of gaze and feature points near the eyes cannot be set, but the intervals between the feature points near the eyebrows, nose, cheeks, mouth (lips), and chin are set on the left and right sides of the face. By comparing, the orientation of the face can be determined. In the case where the mask of FIG. 12 is applied, the orientation of the face can be determined by comparing the distance between the feature points near the eyebrows and the eyes with the right and left sides of the face.

  FIG. 13 is a flowchart illustrating a process of determining the orientation of the face of a person being captured from a captured image. The image processing unit 14 captures a captured image of the camera 13a and detects a face image from the captured image (s41). In s41, the captured image captured in s25 may be used, or the captured image of the camera 13a may be captured again at this time. The image processing unit 14 detects face parts (forehead, eyes, nose, mouth) from the face image detected in s41 (s42). Each face part may be detected by pattern matching or the like as described above.

  If no face part is detected in s42 (s43), the image processing unit 14 determines the face orientation to be indefinite (s44), and ends this process.

  If any of the facial parts can be detected in s42, the image processing unit 14 converts the captured image of the camera 13a captured this time to gray scale (or gradation correction) (s45), and detects each detected facial part. A gazing point is set at a predetermined position (s46). With this gaze point setting, if it is a face image taken from the front, the gaze point can be set at all predetermined locations, but if it is facing the side or face up and down, all It is not possible to set a point of sight at the point of, and some points of sight are missing. Also, when wearing sunglasses, a mask, etc., some points of gaze are missing. The image processing unit 14 determines whether or not all predetermined gazing points have been set (s47). When all the gazing points cannot be set (that is, when there is no gazing point that can be set), the image processing unit 14 determines the face direction to be indefinite at s44 and ends the present processing. In s44, the orientation of the face becomes indefinite, for example, when the camera 13a captures an image of the user from behind, or captures an object similar to a human contour.

  When any gazing point can be set, the image processing unit 14 sets a feature point according to the set gazing point (s48). If all the feature points on the right side of the face cannot be set, the image processing unit 14 determines that the captured image obtained by imaging the left side of the user, that is, the user's face is right sideways with respect to the camera 13a. (S49, s50). Further, if all of the feature points on the left side of the face cannot be set, the image processing unit 14 assumes that the captured image obtained by capturing the right side of the user, that is, the user's face is left sideways with respect to the camera 13a. Determine (s51, s52).

  When one of the feature points can be set on both the right side and the left side of the face, the image processing unit 14 measures the distance between the set left and right feature points from the center line L1 set in the face image ( In step s53, the orientation of the face is determined based on the distance measured here (s54). For example, the distance from the center line L1 is compared for each of two corresponding feature points on the left and right, and if the difference is less than or equal to a predetermined length, it is determined to be approximately the same, and determined to be approximately the same. If the ratio of the feature points exceeds a predetermined ratio (for example, 75%), the face direction may be determined to be the front. If the distance from the center line L1 to the feature point is longer on the left side of the face, it is determined that the face is oriented obliquely to the right with respect to the camera 13a. Conversely, the right side of the face is the center line. If the distance from L1 to the feature point is long, it may be determined that the face is directed diagonally to the left with respect to the camera 13a.

  Further, when the gazing point set for the facial part to be imaged is not set in s46 from the face orientation determined in s54, sunglasses, a mask, and an eye patch are applied, It can also be judged whether the face is upward or downward. For example, when it is determined that the direction of the face is the front, if the gazing point for both eyes is not set, it can be determined that the user is wearing sunglasses. Further, when it is determined that the direction of the face is the front, if the gazing point for one eye is not set, it can be determined that the eye patch is applied. Furthermore, when it is determined that the face is in the front direction, if the gazing point with respect to the mouth cannot be set, it can be determined that the face is masked or facing downward.

  As described above, the image processing unit 14 can determine not only the direction of the face but also whether the user is wearing sunglasses, a mask, or the like.

  The determination of the face orientation described above may be performed by other methods. For example, when wearing glasses or sunglasses, the direction of the hidden eye may be assumed by measuring the shape and direction of the glasses or sunglasses. In addition, as a criterion for determining whether or not the user is facing the front, a device provided with a display screen may be a criterion that the user is facing the front when facing the display screen. It is possible to more accurately determine the person who is going to use the apparatus by specifically setting the determination criterion that the front is facing.

  Furthermore, if you are facing the front of the ATM1 main body, but do not make a transaction after about 10 seconds, or if you are close to the front of the ATM1 main body and looking at a place other than the display 3a, etc. The person may be judged as a suspicious person and an alarm notification may be given. Further, it may be configured to determine whether or not the user is an adult from the face size and shooting height in the captured image, and to switch to the execution mode regardless of the face orientation if the user is an adult. Moreover, you may set the detection height of the sensor 12a to the height which does not detect a child or an infant. In this way, it is possible to prevent children and infants from being detected as users and switching the main body to the execution mode in vain.

  Next, the process which determines whether the user who finished the transaction concerning s9 mentioned above continues a transaction will be described. FIG. 14 is a flowchart showing this process. The ATM 1 waits for a predetermined time (about 5 seconds) to elapse from the completion of the transaction (s61). If the object detection unit 12 detects the user with the sensor 12a when a certain time has elapsed, it is determined that the transaction is continued (s62, s63). On the other hand, if the object detection unit 12a does not detect the user when a certain time has elapsed, that is, if the user who has made the transaction leaves, it is determined that the transaction will not be continued (s62, s64). ).

  Moreover, if the fixed time in s61 is set to about 10 seconds, when another user comes after the user who performed the transaction first leaves, switching between the standby mode and the execution mode is performed wastefully. Can be prevented.

  In addition, if the fixed time in s61 is set to approximately 0, the ATM1 main body can be switched to the standby mode when the transaction processing is completed.

  As described above, in this ATM 1, it is possible to suppress detection of a passerby who is passing around as a user, so that wasteful power consumption can be sufficiently suppressed. In addition, since the start / stop of each unit is not repeated unnecessarily, the life of the ATM 1 main body can be extended.

  In addition, when the sensor 12a detects that an object has entered the detection area around the ATM 1, the camera 13a and the like are activated to determine whether the object that has entered the detection area is a human being. It is not necessary to always start the camera 13a and the like, and the load on the image processing for the captured image of the camera 13a can be suppressed.

  When a user is detected, a guidance screen is displayed on the display 3a, and after accepting a selection input of a transaction type to be executed, supply of operating power is started for units not involved in the selected transaction type. Since the configuration is such that wasteful power consumption is further suppressed.

  In the above description, the execution mode is maintained or switched to the standby mode depending on whether or not the object detection unit 12 detects the user in s62. However, the image processing unit 14 uses the captured image of the camera 13a. It may be configured to determine whether or not there is a person whose face is facing the front of the ATM 1 main body, and to determine whether to maintain the execution mode or switch to the standby mode based on the determination result.

  Further, the object detection unit 12 described above may be omitted. In this case, the user detection unit 10 may have a configuration in which the image processing unit 14 repeatedly processes the captured image of the camera 13a and detects the user.

  In addition, a separate imaging camera that captures the area around the ATM 1 may be provided, and the camera 13a may be activated when a person is captured in the captured image of the imaging camera.

  In the above embodiment, when the sensor 12a detects an object that has entered the detection area, if the sensor 12a detects the object again after a predetermined time has elapsed, the camera 12a starts imaging, but the sensor 12a detects the object. It is good also as a structure which starts the imaging by the camera 13a at the timing which detected the object which entered the area | region. In this way, the timing at which the guidance screen is displayed on the display 3a is accelerated, and the waiting time of the user who has reached the front of the ATM1 main body can be eliminated or shortened. Therefore, a decrease in user convenience is suppressed.

  In the above embodiment, when a user is detected in s1, a transaction type selection screen is displayed on the display 3a. However, as shown in FIG. 15, a screen for accepting confirmation input as to whether or not to perform a transaction is displayed. It is good also as a structure which displays the selection screen of transaction classification on the indicator 3a at the time of displaying on the indicator 3a and receiving confirmation input. In addition, when a certain amount of time is required from when the user reaches the ATM main body until the transaction processing is actually performed, an advertisement or the like may be displayed on the display 3a.

  The present invention can be applied not only to the ATM 1 described above but also to an apparatus such as a vending machine.
