Description

  The present invention relates to a technique effectively applied to a security device at an entrance of a building or a room.

  In recent years, the number of entrance / exit management devices that manage persons entering and leaving buildings and rooms has increased. For example, an auto-lock entrance is a specific example of an entrance / exit management device. Recently, attention has been paid to security in buildings and rooms, management of personal information, and the like, and the need for such an entry / exit management device is increasing.

  In the entry / exit management device, authentication is performed by using a physical key, an ID card, biometrics information, etc., to determine whether the person who is going to enter / exit is a valid registrant. However, in a conventional entrance / exit management device, when authentication is performed and entry / exit is possible, a person other than the person to be authenticated can enter and exit with the authenticator (hereinafter referred to as “joint”). There is a problem that it becomes possible. The person other than the person to be authenticated is, for example, a person accompanying the person to be authenticated, another person following the person to be authenticated, a suspicious person, or the like.

  As an example of an apparatus for preventing such companionship, there is an apparatus that is provided with a management gate having a weight sensor and determines whether or not traffic is permitted based on the detection result of the weight sensor (see Patent Document 1). However, with this device, it is difficult to determine whether the detected weight is due to the weight of a person or the weight of an object. Therefore, there may be a problem that a person with a lot of luggage cannot pass.

  In addition, as an example of a device for preventing companionship, there is a device in which a user inputs a password and the number of people (see Patent Document 2). In this device, sharing is prevented based on whether or not the number of persons input matches the number of persons estimated from weight and other biological information. However, with this apparatus, the user needs to input the number of persons and the code code one by one, which causes trouble for the user. Furthermore, even if the number of people is accurate, it is difficult to say that security is maintained because it is unclear who is included in the user.

  Moreover, there exists a T-DAR system as an example of the apparatus for preventing a companion (refer patent document 4). In the T-DAR system, a monitoring area is imaged, and 3D surface analysis for identification and extraction of an object in the field of view are executed from the situation of light and shadow that change in the captured image. In the T-DAR system, the number of people who can enter a room with one entry permission is set to n in advance. For this reason, it is not necessary for the room entrant to input the number of persons entering the room each time. Then, for each entry permission, it is checked whether or not the authorized number of persons has entered the room. That is, it is checked whether or not n persons have entered the room for one entry permission. However, in this system, the number of people who can enter with a single entry permission is determined in advance, so if this system is applied to places where the number of people entering and leaving is unspecified like the entrance of an apartment Problems arise. For example, if there is only one person allowed to enter at a time, even if two people who are trying to enter at the same time are legitimate visitors, these two people must enter at the same time in the T-DAR system. I can't. For example, even if a legitimate visitor tries to enter with a dog, this system does not allow entry.

Moreover, there is a system including two cameras as an example of a system for preventing sharing (see Patent Document 3). In this system, if a moving object is detected by a person other than the authenticated person, the door is not unlocked. The determination detects a moving object from the face color. Therefore, in this case, not only the suspicious person but also the passerby's face is detected, and the registrant may not be able to enter regularly. In addition, when a plurality of registrants enter, even though all the registrants are registrants, it is necessary for each person to enter individually, which is bothersome for the user.

  Thus, there have been several systems that have been proposed to solve the problem of “companion”, and all of them have some problems. Therefore, the present invention solves these problems, and in particular, provides an apparatus capable of restricting, guarding, and recording the entry of non-registrants while allowing a plurality of registrants to enter simultaneously. Objective.

  In order to solve the above problems, the present invention has the following configuration. A first aspect of the present invention is a security device, which includes a first storage unit, a second storage unit, an imaging unit, a detection unit, a first determination unit, a second determination unit, and a security maintenance unit.

  The first storage means stores identification information about a plurality of first registrants. The second storage means stores identification information about the second registrant in association with each first registrant. The first storage unit and the second storage unit may be configured as an integrated storage device, or may be configured as separate storage devices. The first registrant is a person who is allowed to enter and leave the area where security is maintained by the security maintenance means. The second registrant is a person who is allowed to enter and leave the area where security is maintained by the security maintenance means on condition that the corresponding first registrant is accompanied. Other persons are not allowed to enter or leave the area even if the first registrant or the second registrant is accompanied.

  The imaging means images a predetermined area. The predetermined area captured by the imaging means is an area directed from the boundary between the security area and the non-security area (for example, near the entrance / exit or near the gate) to the non-security area. The imaging means can simultaneously image a plurality of persons existing in such a predetermined area. The detection unit detects a human face from the image captured by the imaging unit. The first determination means determines whether or not the face person detected by the detection means is the first registrant based on the identification information stored in the first storage means. This identification information is stored in advance in the first storage means, and may be changed / added / deleted by a predetermined user. At this time, the predetermined user is, for example, an administrator of the security device, and it is desirable for security that the first registrant and the second registrant are not included.

  The second determination means determines whether or not the face person detected by the detection means is the second registrant based on the identification information about the second registrant stored in the second storage means. However, the second determination means is based on only the identification information about the second registrant stored in the second storage means in association with a certain first registrant among the identification information stored in the second storage means. Make a decision. A certain first registrant is a first registrant determined to be present in the image by the first determination means. Further, the second determination means may determine whether or not only the person who is determined not to be the first registrant among the faces detected by the detection means is the second registrant.

The security maintaining means performs an operation for maintaining security based on the results of the first determination means and the second determination means. For example, the security maintenance means may cancel the security maintenance state when all detected persons are judged as the first registrant or the second registrant by the first judgment means or the second judgment means. It may work. For example, if there is a person who is determined not to fall under either the first registrant or the second registrant among the detected persons, for example, the first registration among the detected persons. Even if there is a person, it may operate to maintain the security maintenance state. An operation for maintaining security is an operation that prohibits people who have been imaged by the imaging means from entering the security area (for example, the interior of a building, a room, or a predetermined section) (for example, an operation to close a door, Operation to close the door lock, etc., operation to maintain this admission prohibition operation, operation to notify a predetermined report destination (for example, police or security company), or predetermined contact (for example, detected by detecting means) Notification (such as sending an e-mail or sending an image) or a warning to the mobile terminal of the first registrant and / or the second registrant and the mobile terminal of the person registered in advance as its guardian) Any operation can be used as long as security can be maintained, such as an operation to sound a sound, an operation to turn on / flash a light, or an operation to perform a warning by voice.

  In the security device according to the first aspect configured as described above, it is determined whether or not the person in the captured image is a first registrant and a second registrant. In addition, the identification information used when it is determined whether or not it is the second registrant is the identification information about the second registrant stored in association with the first registrant determined to be present in the image. Only. For this reason, even if it is registered in the second storage means as the second registrant (that is, even if the identification information is stored), the second registrant is determined as the second registrant only by that fact. There is nothing. That is, in order for the second registrant to be determined as the second registrant by the second determination means, the corresponding first registrant needs to be determined by the first determination means. In other words, the second registrant is not determined as the second registrant unless accompanied by the corresponding first registrant. Then, according to the determination results of the first determination unit and the second determination unit, the security maintaining unit performs an operation for maintaining the security. For this reason, as compared with the case where the operation for maintaining the security is performed based only on whether or not the detected person is a “registrant” as in the past, it is possible to respond more realistically. Become.

  For example, consider a case where the first registrant sets the friend as the second registrant in association with himself / herself. Then, this second registrant is not determined as a second registrant alone. For this reason, the security operation continues. On the other hand, when the second registrant is imaged and detected together with the first registrant, the second registrant is determined as the second registrant, and the two are determined as the first registrant and the second registrant. Is done. In this way, by registering a friend of the first registrant as a second registrant, if the friend is alone or with a different first registrant (the first registrant who is another person for this friend) It is possible to change the response by the security maintenance means when the first registrant is accompanied.

  According to the first aspect of the present invention, either of the first registrant and the second registrant is determined by the first determination means and the second determination means among the images of each person detected by the detection means. It may be configured to further include a recording means for recording an image of a person who is determined not to exist.

  With this configuration, it is possible to keep a record of a person who can be estimated as a so-called suspicious person, that is, a person who has not been determined as a first registrant or a second registrant.

The first aspect of the present invention may be configured to further include a position estimation unit, an input unit, and an instruction unit. The position estimating means estimates the position of each person detected by the detecting means from the captured image. For example, the position estimating means may be configured to acquire the size of the detected person's face and estimate that the person with the largest size is present at the position closest to the imaging means. The position estimating means obtains the distance between a predetermined position in the image (for example, the position where the input means is installed) and the position of each face, and estimates that the person with the shortest distance is closest to the input means. It may be configured as follows.

  The input means is used by the user to instruct release of the security maintenance state by the security maintenance means. The release of the security maintenance state means that the operation by the security maintenance means becomes invalid for a predetermined period.

  When the position estimating unit estimates that the position of the first registrant is a predetermined position, the instructing unit is in a security maintaining state with respect to the security maintaining unit when an input for instructing cancellation is made by the input unit. Instruct to cancel. For example, the instruction unit may be configured to issue an instruction when an input is made by the input unit when the position of the first registrant is estimated to be the closest position to the imaging unit. However, in this case, it is desirable that an input unit be provided near the imaging unit. Further, for example, it may be when the position of the first registrant is estimated to be closest to the position of the input means set as the predetermined position in the image. With such a configuration, the release of the security maintenance state is effective only when it is estimated that the input unit has been operated by the first registrant. Therefore, even if the input unit is operated by a suspicious person or the like, it is possible to maintain security without releasing the security maintenance state.

  The second aspect of the present invention is a storage means, and includes a first storage area and a second storage area. Identification information about a plurality of first registrants permitted to enter the security area is stored in the first storage area. In the second storage area, identification information about the second registrant permitted to enter the security area is stored in association with the predetermined first registrant only when the predetermined first registrant is accompanied. . By constructing a security device using such storage means, it is possible to construct a security device as in the first aspect of the present invention, and the same effect can be obtained.

  In the second aspect of the present invention, addition, change, or deletion of information in the first storage area may be configured to be changed only by an administrator of the security area. Moreover, the addition, change, and deletion of information in the second storage area may be configured to be changed only by the corresponding first registrant.

  By the way, when a companion occurs, the detected registrant is informed by knowing who the person is with, who is another registrant, or who is not a registrant. It is possible to prevent danger. Therefore, such a device is also required. Japanese Laid-Open Patent Publication No. 2003-219396, which is a prior art, discloses an apparatus that can clearly display on a mobile terminal screen a video of a person who has entered a head of a visitor or a house in a moving image captured by a camera. Has been. However, with this device, it is possible to display an image of a person detected within a certain area on a mobile terminal, but what kind of person the person detected with a registrant is? Judgment is not made. Therefore, even if such an apparatus is applied, the request of the registrant cannot be sufficiently met.

  In response to such a demand, a third aspect of the present invention is a security device, which includes an imaging unit, a detection unit, a determination unit, and a notification unit. The imaging means images a predetermined area. The predetermined area is, for example, an area near the entrance when the security apparatus is installed at the entrance of a building, and an area near the entrance when the security apparatus is installed at the entrance of a room. .

The detection unit detects a human face from the image captured by the imaging unit. The determining means determines whether or not the person with the face detected by the detecting means is a registrant registered in advance. When the determination unit determines that the registrant and the non-registrant are captured in the captured image, the notification unit notifies the contact registered in advance in association with the registrant. . The contact information may be, for example, the phone number or email address of a mobile terminal possessed by the registrant, the phone number or email address of the mobile terminal possessed by the registrant's guardian, It may be a telephone number or e-mail address at home or the like, or may be a security company, a management room, a police, or the like.

  According to the third aspect of the present invention configured as described above, for example, when a contact is set as a portable terminal of a registrant, registration is performed when a registrant and a non-registrant are detected. A person can know the existence of a person who is not a registered person by notification. Also, for example, when the contact is a registrant's guardian, etc., when a registrant and a non-registrant are detected, the guardian can know the presence of a person who is not a registrant by notification. .

  The first aspect and the third aspect of the present invention may be realized by executing a program by an information processing apparatus. That is, the present invention specifies the processing executed by each means in the first aspect and the third aspect as a program for causing the information processing apparatus to execute or a recording medium on which the program is recorded. Can do. Further, the present invention may be specified by a method in which the information processing apparatus executes the processing executed by each of the above-described means.

  According to the present invention, it is bothered by the user even when a plurality of people are detected by determining whether the detected person is a first registrant, a second registrant, or any other person. It is possible to take measures to maintain the security without giving a sense of security.

[First embodiment]
〔System configuration〕
First, the security apparatus 1a which is 1st embodiment of the security apparatus 1 is demonstrated. The security device 1 is installed at the boundary between an area where it is necessary to limit the number of people entering and exiting (hereinafter referred to as “security area”) and an area where it is not (hereinafter referred to as “non-security area”). , Restricting the entry and exit of people into the security area. The security device 1a determines a person who should be allowed to enter and leave the security area and a person who is not allowed to enter and exit, and performs an operation for maintaining security.

The security device 1a includes a CPU (central processing unit), a main storage device (RAM), an auxiliary storage device, and the like connected via a bus in terms of hardware. The auxiliary storage device is configured using a nonvolatile storage device. The nonvolatile storage device referred to here is a so-called ROM (Read-Only Memory: including EEPROM (Erasable Programmable Read-Only Memory), EEPROM (Electrically Erasable Programmable Read-Only Memory), mask ROM, etc.), FRAM (Ferroelectric RAM). ), Hard disk, etc.

  FIG. 1 is a diagram showing functional blocks of the security device 1a. The security device 1a loads various programs (OS, applications, etc.) stored in the auxiliary storage device into the main storage device and is executed by the CPU, whereby the imaging unit 2, the detection unit 3, the first storage unit 4, It functions as an apparatus including the second storage unit 5, the first determination unit 6, the second determination unit 7, the security maintenance unit 8, and the like. In addition, the detection part 3, the 1st judgment part 6, and the 2nd judgment part 7 are implement | achieved when a program is run by CPU. The detection unit 3, the first determination unit 6, and the second determination unit 7 may be configured as a dedicated chip. Next, each functional unit included in the security device 1a will be described.

<Imaging section>
The imaging unit 2 is configured using a digital still camera, a digital video camera, or the like, and images a scene in a range monitored by the security device 1a. The imaging unit 2 passes the captured image data to the detection unit 3. Any existing technology may be applied to the imaging unit 2 as long as imaging can be performed. For example, the imaging unit 2 may be configured using a CCD (Charge-Coupled Devices), a CMOS (Complementary Metal-Oxide Semiconductor) sensor, or the like.

<Detection unit>
When receiving the image data from the imaging unit 2, the detection unit 3 detects a human face from the image. The detection unit 3 may be configured to detect a face by template matching using a reference template corresponding to the outline of the entire face, for example. The detection unit 3 may be configured to detect a face by template matching based on face components (eyes, nose, ears, etc.). Moreover, the detection part 3 may be comprised so that the area | region close | similar to the color of skin may be detected, and the area | region may be detected as a face. Further, the detection unit 3 may be configured to perform learning based on a teacher signal using a neural network and detect a face-like region as a face. Further, the face detection process by the detection unit 3 may be realized by applying any other existing technique.

<First storage unit>
The first storage unit 4 is configured using a so-called nonvolatile storage device. FIG. 2A is a diagram illustrating an example of data stored in the first storage unit 4. The 1st memory | storage part 4 matches and memorize | stores the identification information about the 1st registrant, and its ID. The first registrant is a person who can enter and exit the security area independently. The identification information is data necessary for the first determination unit 6 to perform the person identification process, and is a value unique to each person. For example, the identification information may be a feature amount acquired from an image of the person's face. Specifically, it is a shading pattern acquired from a face image, a combination of feature amounts at each feature point of the face, or the like.

  The contents of the data stored in the first storage unit 4 can be changed / deleted / added only by the administrator of the security device 1a.

<Second storage unit>
The second storage unit 5 is configured using a so-called nonvolatile storage device. FIG. 2B is a diagram illustrating an example of data stored in the second storage unit 5. The 2nd memory | storage part 5 matches and memorize | stores the identification information about a 2nd registrant, its ID, and ID (1st registrant ID) of the 1st registrant corresponding to each 2nd registrant. The second registrant is not allowed to enter or leave the security area alone. Further, even if the second registrant is accompanied by another first registrant (a non-corresponding first registrant), the second registrant is not allowed to enter or leave the security area unless he is with the corresponding first registrant. That is, if the second registrant is with the corresponding first registrant, entry / exit into the security area is allowed.

  The contents of the data stored in the second storage unit 5 can be individually changed / deleted / added by each first registrant. However, each first registrant can change / delete / add only the contents of data about the second registrant corresponding to the first registrant.

<First judgment part>
The first determination unit 6 performs an identification process based on the identification information stored in the first storage unit 4 in order to determine who the person of the face detected by the detection unit 3 is. The 1st judgment part 6 is realizable by applying the technique described in the following literature, for example.

Kurita Takio, “Statistical Method for Face Detection / Face Recognition”, [December 14, 2004 search],
Internet <URL: http://www.neurosci.aist.go.jp/~kurita/lecture/statface.pdf>

<Second judgment part>
The second determination unit 7 performs identification processing based on the identification information stored in the second storage unit 5 in order to determine who the person of the face detected by the detection unit 3 is. However, the second determination unit 7 performs the identification process based on only the identification information corresponding to the first registrant detected by the first determination unit 6 among the identification information stored in the second storage unit 5. At this time, the second determination unit 7 may be configured to perform the identification process only on the person who is not determined to be the first registrant among the persons of the face detected by the detection unit 3. By comprising in this way, the duplication identification process about the person already known with the 1st registrant can be omitted.

<Security Maintenance Department>
The security maintenance unit 8 allows or restricts entry into and exit from the security area. The security maintaining unit 8 controls, for example, opening / closing of a door and opening / closing of a key provided between a security area and a non-security area. Further, the security maintaining unit 8 may control the sounding of an alarm, or may control the blinking / lighting of illumination (such as a rotating light or a spotlight). Moreover, the security maintenance part 8 may control the report to a police, a security company, etc.

  If there is a person who is neither the first registrant nor the second registrant (hereinafter referred to as “suspicious person”) in the image, the security maintaining unit 8 may It is configured to continue the maintenance state. The security maintenance unit 8 is configured to cancel the security maintenance state when there is no suspicious person in the image.

  The security maintaining unit 8 may be configured to perform different operations depending on the number of suspicious persons and the number of persons determined to be the first registrant or the second registrant. For example, when the number of suspicious persons is the same as or larger than the number of first registrants or second registrants, the security maintenance unit 8 is configured not to open the doors and keys. For example, when the number of suspicious persons is smaller than the number of first registrants or second registrants, the security maintaining unit 8 opens the doors and keys and records the images of suspicious persons in the recording unit. It may be configured. For example, when the number of suspicious persons is zero, the security maintaining unit 8 may be configured not to perform recording in the recording unit.

[Operation example]
FIG. 3 is a flowchart illustrating an operation example of the security device 1a. First, the imaging unit 2 captures an image of a predetermined area (S01). The detection unit 3 detects a human face from the image captured by the imaging unit 2 (S02). The first determination unit 6 determines whether each person detected by the detection unit 3 is a first registrant (S03). When the first registrant is not among the detected people (S04-None), the security maintenance unit 8 continues the security maintenance state (S07).

  On the other hand, when there is the first registrant (S04-present), the second determination unit 7 reads out the identification information of the second registrant corresponding to the detected first registrant, and other detectors (first registration). It is determined whether or not the detected person other than the person who is determined to be a person is a second registrant (S05). If the detected person includes a so-called suspicious person who is neither the first registrant nor the second registrant (S06 present), the security maintenance unit 8 continues the security maintenance state (S07). On the other hand, if there is no suspicious person among the detected persons (S06-No), the security maintenance unit 8 temporarily releases the security maintenance state (S08).

[Action / Effect]
According to the security device 1a, whether to enter or leave the security area is not determined based on whether or not the user is a registrant, but whether or not he / she is a first registrant and the second registrant corresponding to the accompanying first registrant. Judgment can be made based on two criteria of whether or not he is a registered person. Therefore, compared with the conventional case where it is determined only by whether or not the user is a registrant, the security maintenance state is continued unnecessarily and the first registrant and the second registrant are not bothered effectively. It becomes possible to prevent.

  In addition, the data in the first storage unit 4 can be rewritten only by the administrator of the security device 1a. Therefore, only the administrator can manage the first registrant who is allowed to enter and leave the security area alone, and security can be maintained. Moreover, the data in the 2nd memory | storage part 5 can rewrite only about the data about the 2nd registrant corresponding to each 1st registrant. Therefore, each first registrant can register himself / herself without inquiring of the administrator about the second registrant who may allow entry into and exit from the security area if he / she is accompanied by himself / herself. Therefore, it is possible to reduce the time and labor required for rewriting data on the second registrant. At this time, a certain first registrant cannot rewrite the data of the second registrant corresponding to the other first registrant. For this reason, while being able to protect the privacy etc. of a 1st registrant, the security in a security area | region can be maintained. Note that the data in the second storage unit 5 may be configured to be rewritten by the administrator.

  Next, an application example of the security device 1a will be described. For example, when the security device 1a is installed at the entrance of an apartment, the first registrant may be set as a resident of the apartment, and the second registrant may be set as a friend or relative of each resident. When the security device 1a is installed at the entrance of a room for storing confidential data, the first registrant may be set as a person who is permitted to access the confidential data. In this case, the second registrant is set as a person managed by each person permitted to access (for example, if the first registrant is a general manager, a subordinate assigned to the same department). May be. Further, when the security device 1a is installed at the entrance to an area where dangerous goods are handled, the first registrant may be set as a person who can handle dangerous goods. In this case, the second registrant may be set as a person who is permitted to handle dangerous goods on the condition that there is support from a person who can handle dangerous goods.

[Modification]
The first storage unit 4 and the second storage unit 5 may be configured on an integrated storage device. Further, the first determination unit 6 and the second determination unit 7 may be configured as an integrated determination unit. In this case, the integrally configured determination unit first determines whether each detected person is the first registrant. And the judgment part comprised integrally determines whether it is the 2nd registrant corresponding to the detected 1st registrant about each detected person.

[Second Embodiment]
Next, a security device 1b that is a second embodiment of the security device 1 will be described.

〔System configuration〕
FIG. 4 is a diagram illustrating an example of functional blocks of the security device 1b. The security device 1b differs from the security device 1a in that it further includes a recording unit 9, a position estimation unit 10, an input unit 11, and an instruction unit 12.

<Recording section>
The recording unit 9 is configured using a so-called nonvolatile storage device. The recording unit 9 records an image of a person who is determined to be neither the first registrant nor the second registrant among the images of the person detected by the detection unit 3. For example, it can be realized by the recording unit 9 recording only the image of the person who has not been determined to be the second registrant among the human face images used for the determination by the second determination unit 7.

<Position estimation unit>
The position estimation unit 10 estimates the position of each person detected by the detection unit 3. The position estimation unit 10 is configured not to estimate the positions of all persons detected by the detection unit 3 but to estimate only the positions of the persons determined to be the first registrant by the first determination unit 6. May be.

  For example, the position estimation unit 10 may estimate the position based on the size of the face image of the person. Specifically, the position estimation unit 10 may estimate that the person with the largest face size is at the position closest to the imaging unit 2. Further, the position estimation unit 10 may estimate that a person whose face is present in a predetermined area in the captured image is at a position closest to the input unit 11. The position estimation unit 10 passes the estimation result to the instruction unit 12.

<Input section>
The input unit 11 is configured using an input device such as a button or a touch sensor. The input unit 11 may be provided in the immediate vicinity of the imaging unit 2 or may be provided in a place different from the imaging unit 2. When an input is made by the user via the input unit 11, the fact that there is an input is passed to the instruction unit 12.

<Indicator>
The instruction unit 12 instructs the security maintenance unit 8 to release the security maintenance state based on the information passed from the position estimation unit 10 and the input unit 11. The instructing unit 12 instructs to cancel the security maintaining state when the input unit 11 inputs an instruction to cancel when the position of the first registrant is estimated to be a predetermined position. .

  For example, when the input unit 11 is provided near the imaging unit 2, it is estimated that the person estimated to be closest to the imaging unit 2 is closest to the input unit 11. That is, when there is an input from the input unit 11 while being estimated in this way, it can be estimated that the input unit 11 is operated by a person who is estimated to be closest to the imaging unit 2. Then, the instruction unit 12 issues a release instruction when an input is made by the input unit 11 while the position of the first registrant is estimated to be closest to the imaging unit 2. Further, for example, it may be when the position of the first registrant is estimated to be closest to a predetermined position in the image (a position where the input unit 11 is provided).

[Operation example]
FIG. 5 is a flowchart showing an operation example of the characteristic processing portion of the security device 1b. Basically, the processing flow of the security device 1b is the same as that shown in FIG. 3, but when the input unit 11 is operated, the processing shifts to the processing shown in FIG. First, based on the estimation result of the position estimation unit 10 and the determination result of the first determination unit 6, the instruction unit 12 estimates who is closest to the input unit 11 (S09, S10). If this person is not the first registrant (S11-No), since the instruction unit 12 does not give an instruction to the security maintenance unit 8, the security maintenance state is continued (S12). On the other hand, when this person is the first registrant (S11-Yes), the instruction unit 12 instructs the security maintenance unit 8 to release the security maintenance state, and the security maintenance state is released (S13).

[Action / Effect]
With this configuration, the release of the security maintenance state is effective only when it is estimated that the input unit 11 has been operated by the first registrant. Therefore, even if the input unit 11 is operated by a suspicious person or the like, it is possible to maintain security without releasing the security maintenance state.

  In addition, since an image of a person who has not been determined as a first registrant or a second registrant, that is, an image of a suspicious person is accumulated in the recording unit 9, the crime prevention effect is enhanced by using this image later as a log. Things will be possible.

[Third embodiment]
Next, a security device 1c that is a third embodiment of the security device 1 will be described.

〔System configuration〕
FIG. 6 is a diagram illustrating an example of functional blocks of the security device 1c. The security device 1c includes an imaging unit 2, a detection unit 3, a storage unit 13, a determination unit 14, and a notification unit 15. Since the imaging unit 2 and the detection unit 3 are not different from the above configuration, the description thereof is omitted.

<Storage unit>
The storage unit 13 is configured using a so-called nonvolatile storage device. The storage unit 13 stores the identification information of the registrant who is allowed to enter and leave the security area and the contact information set for the registrant in association with each other. The contact may be the phone number or email address set on the mobile device owned by this registrant, or the phone number or email address set on the mobile device owned by the parent of this registrant. There may be. In addition, any contact address may be set as long as it is a contact address related to the registrant.

<Judgment part>
The determination unit 14 determines who the person detected by the detection unit 3 is based on the identification information stored in the storage unit 13. Then, the determination unit 14 instructs the notification unit 15 to make a notification when the detected person includes a registrant and a non-registrant. At this time, the determination unit 14 passes the contact information stored in the storage unit 13 in association with the detected registrant to the notification unit 15.

<Notification part>
When a contact is given from the determination unit 14, the notification unit 15 notifies the contact with a warning or the like. At this time, the notification unit 15 may be configured to further transmit an image of a face of a person who is determined not to be a registered person.

[Operation example]
FIG. 7 is a flowchart illustrating an operation example of the security device 1c. The imaging unit 2 captures an image (S14), and the detection unit 3 detects a human face from the image (S15). The determination unit 14 determines whether each detected person is a registered person (S16). If the registered person and the unregistered person (suspicious person) are mixed in the detected person (S17-Yes), the determination unit 14 instructs the notification unit 15 to notify the user. And the notification part 15 performs notification (S18). On the other hand, when there are only registrants or only suspicious persons, the notification unit 15 does not notify (S17-No). At this time, when only the registrant is present, a security maintenance unit (not shown) may be configured to cancel the security maintenance state.

[Action / Effect]
According to the security device 1c, for example, when a contact is set as a registrant's mobile terminal, when a registrant and a suspicious person are detected, the registrant can know the presence of the suspicious person by notification. It becomes possible. For example, when the contact is a registrant's guardian or the like, when a registrant and a suspicious person are detected, the guardian or the like can know the presence of the suspicious person by notification.
