     SUMMARY OF THE INVENTION 
     Problems to be Solved by the Invention 
     However, privacy is not protected in a captured image, and even if the automation of the surveillance camera advances, it cannot always be stated that a person who monitors the image is never malicious since the person is a human although the purpose is monitoring, and it cannot be denied that the image captured for the monitoring purpose may be used for wrong purposes. Also, even if the automation of the surveillance camera advances as described above, the final decision on an accident or a crime needs to be made by a person, and in such a case as well, whether the privacy of a subject is completely protected is not always guaranteed. 
     Under such circumstances, the present invention solves the above problems, and an object of the present invention is to provide a monitoring information management system, a monitoring information management program, and a monitoring information management method capable of further enhancing protection of the privacy of a subject as well as reducing a burden on an observer by automatically detecting occurrence of an abnormality in a monitoring system and excluding a human from monitoring.

Also, in the above-described aspect of the invention, the support base preferably further includes a power supply means that supplies power to the power transmission coil, and a suspension means that suspends the camera housing supported via the support surface. 
     Effects of the Invention 
     As described above, according to the above invention, for an image or a moving image captured by the image capturing device, the image monitoring unit including a technology such as artificial intelligence (AI) automatically recognizes a change in a person, an action, or an event appearing in recorded data captured by the image capturing device and detects an abnormality appearing in the recorded data. Therefore, it is possible to prevent a human from viewing the monitored image. Also, since the installation place of the image capturing device is disclosed on a map through a communication network, the fact that the place is a monitoring target can be disclosed in advance, which can be a deterrent for preventing a crime before it occurs. As a result, by excluding a human from monitoring, it is possible to further enhance protection of the privacy of a subject as well as reducing a burden on an observer. 
     Also, by performing mosaic processing in which a subject appearing in an image or a moving image captured by the image capturing device is blurred so as to be invisible, a state of preventing a human from viewing the monitored image can be achieved more reliably, and protection of privacy of the subject can further be enhanced. 
     In particular, restoration processing of deblurring, in a step-by-step manner, a blurred portion can be performed on the blurred recorded data, a protocol (procedure) of removing a mosaic as needed can be set as a system of the priority order of image blurring and the release authority. By doing so, a system of authorization in a range from a state where a human cannot view a monitored image to a state where the human can view the image can be provided, and so-called privacy control can be achieved. 
     For example, the aforementioned privacy control enables information specifying an individual in a monitored image to be acquired only in a step-by-step manner in the following order. 
     1) Mosaic on all 
     2) Mosaic on all except faces 
     3) Mosaic on place and things 
     4) Mosaic on persons 
     5) Mosaic on faces 
     Hence, for example, by enabling blurring of the persons and the place to be released in a step-by-step manner, the monitored image can effectively be used while the privacy of the persons captured is protected as in a case where only the behaviors of the persons can be checked without clarifying the place, in a case where, by clarifying the place and enabling the detailed behaviors of the persons to be visually recognized, the persons do not need to be specified, but the state of an accident or an incident having occurred at the place needs to be checked to some extent, or in another case, which is effective in preventing a crime and solving an incident. 
     Also, by setting an access protocol (procedure) in terms of information security as a system of managing access authority for releasing blurring, so-called access control can be implemented. As for the strength of the access authority, authority levels that can be released in a step-by-step manner are set as in the following example. 
     1) Court order of disclosure 
     2) Warrant of investigative organization 
     3) Security officer 
     4) General manager or the like 
     5) Manager or the like 
     6) Chief/store manager or the like 
     7) Regular employee 
     8) Other authorized staff 
     In a case where a person exercises the access authority and executes the privacy control to perform deblurring processing on the recorded data, information about the person who has executed the deblurring processing is disclosed to an unspecified large number of general viewers through a communication network. Thus, the general public can constantly check through the communication network that the privacy in the image captured by the surveillance camera is not violated, and it is possible to prevent the installer of the camera from viewing the monitored image for the purpose of abuse. 
     Furthermore, with the image capturing device according to the present invention described above, the camera housing is detachably supported on the support base by the magnetic force via the support surface, and the power reception coil is charged in a non-contact manner via the power transmission coil. Therefore, installation and operation of the camera are facilitated, and the degree of freedom of the installation place can be improved.

Note that, in the present embodiment, the case where an owner of the monitoring device is also an installer who installs the monitoring device and where the installer is also an observer will be described as an example. However, the owner, the installer, the administrator, and the observer of the monitoring device may be different parties, and in this case, it is preferable to separate the access authorities of the respective parties and distinguish them by unique IDs. 
     Mainly used as the recorded data for use in monitoring are an image or a moving image captured by a surveillance camera  2  as illustrated in  FIG.  2   , a sound recorded by a sound microphone, and detection data acquired from various sensors such as an infrared sensor, an illuminance sensor, a motion sensor, a temperature sensor, and an odor/smoke sensor.

In the present embodiment, the communication interface  54  transmits various requests and authentication information to the monitoring information management server  3  through the communication network NW, and receives data such as a web page from the monitoring information management server  3 . 
     (Monitoring Information Management Method) 
     A monitoring information management method can be carried out by operating the monitoring information management system having the above configuration.  FIGS.  6  to  9    are flowcharts illustrating the monitoring information management method according to the present embodiment. Note that the processing procedure described below is illustrative only, and each piece of processing may be changed as much as possible. Also, regarding the processing procedure described below, it is possible to appropriately omit, replace, and add steps depending on the embodiment. 
     (1) Operation when New Surveillance Camera is Installed 
     First, an operation when a surveillance camera is installed will be described.  FIG.  6    is a flowchart illustrating an operation when a surveillance camera is installed in the monitoring information management system according to the present embodiment. 
     As illustrated in the figure, the surveillance camera  2  that captures an image of a place to be monitored is installed at a predetermined place (S 101 ). After the installation, a communication connection with the terminal device  5  used by the installer Um is established by the connection processing unit  27  (S 102  and S 103 ). In this communication establishment, both the new surveillance camera  2  and the terminal device  5  are located in the common Wi-Fi network, and wireless communication is established between these devices. Subsequently, using this established communication, various settings are performed in the surveillance camera  2  from the terminal device  5  (S 104  and S 105 ). In this setting, first, information necessary for wireless connection of the surveillance camera  2  with the wireless base station  4 , the relay device  6 , and the monitoring information management server  3  is set by the execution condition setting unit  25   a.    
     As a result, the surveillance camera  2  is connected to the monitoring information management server  3  through the communication network NW, and information can be distributed to the general terminals  8  dispersedly arranged on the communication network NW through the monitoring information management server  3 . Furthermore, the settings by the execution condition setting unit  25   a  include settings related to monitoring conditions. The monitoring conditions to be set include conditions of moving object detection (a monitoring range, detection sensitivity, and a drive time zone), operations at the time of abnormality detection (settings of e-mail transmission and transfer of a still image and a moving image file), and the like. 
     Subsequently, the terminal device  5  executes a registration procedure of a new surveillance camera to the monitoring information management server  3 . Specifically, the terminal device  5  accesses the installer registration unit  311  provided in the monitoring information management server  3 , and transmits owner identification information such as a user ID as an administrator to the monitoring information management server  3  (S 106 ). In the monitoring information management server  3 , which has received the owner identification information (S 107 ), authentication processing is performed in the authentication processing unit  313  using the received owner identification information (S 108  and S 109 ), and in a case where the authentication is successful, registration processing for the camera information is performed in the installer registration unit  311 . 
     In the camera information registration processing, first, the terminal device  5  acquires installation position information determined in the surveillance camera  2  (S 110 ). Examples of a method of determining the installation position information include a method of acquiring the position information by the surveillance camera  2  itself and a method of using the position information of the surveillance camera  2  detected in the terminal device  5  or the monitoring information management server  3 . The position information of the surveillance camera  2  installed in this manner and the user ID of the installer Um who is the owner of the camera are registered in association with each other (S 112 ). 
     (2) Operation During Monitoring 
     Next, an operation at the time of monitoring using the surveillance camera installed in this manner will be described.  FIG.  7    is a flowchart illustrating a monitoring operation of the surveillance camera in the monitoring information management system according to the present embodiment, and  FIG.  8    is a flowchart illustrating an operation at the time of abnormality detection performed by the surveillance camera in the monitoring information management system according to the present embodiment. 
     As illustrated in  FIG.  7   , when monitoring processing is started, first, connection processing is executed between the surveillance camera  2  and the monitoring information management server  3  (S 201  and S 202 ), and after the connection processing is established, the surveillance camera  2  starts monitoring and image capturing. Subsequently, the monitoring state notification unit  25   b  sequentially transmits recorded data to the monitoring information management server  3 , and in the monitoring information management server  3 , which has received the recorded data, the monitoring device management unit  314  accumulates the recorded data received by a recorded data collection unit  305  in the recorded data accumulation unit  320   c  (S 203  and S 204 ). For the accumulated recorded data, the edit processing unit  314   a  of the monitoring information management server  3  executes image edit processing for performing predetermined blurring processing on the recorded data, and the edited recorded data is accumulated in the recorded data accumulation unit  320   c  (S 205 ). 
     Also, in the monitoring information management server  3 , the disclosed information management unit  312  generates disclosed information (S 206 ). The disclosed information includes installation position information for the surveillance camera, information regarding the installer, a release level of the blurring processing at the present time, and the like. The generated disclosed information is distributed from the disclosed information distribution unit  303  and the communication unit  302  to the general viewer Ua through the communication network NW (S 207 ). 
     Thereafter, as illustrated in  FIG.  8   , abnormality detection processing is executed in the image monitoring unit  25   d  of the surveillance camera  2  or the monitoring device management unit  314  and the image monitoring unit  314   d  of the monitoring information management server  3 . Specifically, in loop processing, normal image capturing processing is continued until an abnormality is detected (“N” in S 302 ). Then, in a case where an abnormality is detected in the drive state of the monitoring device (including the surveillance camera  2  and the support base  20 ) or in the captured image (“Y” in S 301 ), an abnormality occurrence notification is generated and transmitted from the monitoring state notification unit  25   b , the notification unit  314   e , or the disclosed information management unit  312  through the monitoring information management server  3 , the terminal device  5 , or another information terminal to the observer (S 302 ). The abnormality occurrence notification includes the fact that an abnormality has occurred and the type of the abnormality, and the image data or sound data file serving as a basis (or address information such as a URL indicating a storage location of the data file) is attached. The terminal device  5 , which has received the abnormality occurrence notification, performs processing for displaying and outputting an alert, and the monitoring information management server  3  accumulates information regarding the generated abnormality and discloses the information as disclosed information from the disclosed information distribution unit  303  through the communication network NW so as to be viewable. 
     (3) Operation at Time of Information Disclosure 
     Next, processing for disclosing information captured by the surveillance camera will be described.  FIG.  9    is a flowchart illustrating an operation at the time of disclosing information related to the surveillance camera in the monitoring information management system according to the present embodiment. Here, a case where the owner of the surveillance camera views recorded data captured by the camera in which an abnormality is detected will be described as an example. 
     First, the terminal device  5  accesses the monitoring information management server  3  to perform authentication processing, and a viewing request indicating that viewing is desired is transmitted from the execution processing unit  25   c  to the monitoring information management server  3  (S 401 ). Subsequently, in a case where the authentication processing is successful, the release level control unit  312   b  confirms the viewing authority of the accessor who has transmitted the viewing request (S 402 ). In a case where the viewing authority of the accessor is confirmed, the installer Um, who is the authorized accessor, sets a desired release level and transmits the release level to the monitoring information management server  3 . The monitoring information management server  3  having received the setting of the release level makes a determination of the release level (S 404 ). 
     More specifically, for the abnormality detected by the image monitoring units  25   d  and  314   d , the AI included in the release level control unit  312   b  determines whether or not an image thereof needs to be checked in accordance with the incident (case) such as an accident or an incident that has occurred. When the AI of the release level control unit  312   b  determines that the image needs to be checked, the AI specifies a portion (a person, a face, a body, with whom, time, a place, a thing, how (means), and the like) in the image necessary to specify when, where, who, with whom, and what is being done on the basis of the protocol of the privacy control in accordance with the level at which the blurring processing is released, and determines a release level for visibility. 
     Subsequently, the determination by the release level control unit  312   b  is input into the monitoring device management unit  314 , and the edit processing unit  314   a  and the restoration processing unit  314   b  execute deblurring (restoration) processing in accordance with the determined release level (S 405 ). This restoration processing will be described in detail. As for the recorded data accumulated in the monitoring information management server  3 , the entire image is clear so that the persons and the place can be specified in the original image before the blurring processing is performed, as illustrated in  FIG.  10   . For example, as illustrated in  FIGS.  11 A to  11 C , the original image is subjected to processing for blurring the persons in the image and editing processing for removing the buildings, the monument, or the like whose place may be specified so that both the persons and the place cannot be specified. As release levels for blurring the persons and the place, it is possible to set, as illustrated in  FIGS.  11 A to  11 C , a level ( FIG.  11 A ) at which the persons and the place cannot be specified, and only the behaviors of the persons can be visually recognized, a level ( FIG.  11 B ) at which the monument is displayed so that the place can vaguely be specified, and the character information for specifying the place name, the address, and the like is blurred, a level ( FIG.  11 C ) at which the background and the monument are displayed so that the place name can be specified to some extent, and the like. 
     Also, as another method of setting the release levels, a method of making the level of the blurring processing of the persons variable while leaving the place clear is also conceivable. For example, as illustrated in  FIGS.  12 A and  12 B , conceivable levels are a level ( FIG.  12 A ) at which blurring processing such as creating a mosaic is performed on the entire body of each person so that the place can be specified, and so that the flow, the behaviors, and the like of the persons can be confirmed although the faces and the clothes of the persons cannot be specified, and a level ( FIG.  12 B ) at which only the faces of the persons cannot be specified, but the respective detailed behaviors thereof can be visually recognized. 
     As described above, by enabling blurring of the persons and the place to be released in a step-by-step manner, the monitored image can effectively be used while the privacy of the persons captured is protected as in a case where only the behaviors of the persons can be checked without clarifying the place, in a case where, by clarifying the place and enabling the detailed behaviors of the persons to be visually recognized, the persons do not need to be specified, but the state of an accident or an incident having occurred at the place needs to be checked to some extent, or in another case, which is effective in preventing a crime and solving an incident. 
     Then, the fact that the owner has exercised the authority to perform processing of deblurring the recorded data in this manner is recorded, and the recorded data is distributed on the communication network NW as disclosed information and is disclosed to an unspecified number of general terminals  8 . Specifically, the installation position information for the surveillance camera, the release level at that time, and the restoration history information for specifying the person who has executed the release of the blurring (the installer who has exercised the release authority) are recorded in the disclosed information database  320   b , and disclosed information including the restoration history information is generated in the disclosed information management unit  312  (S 406 ), distributed from the disclosed information distribution unit  303  to the communication network NW, and made viewable by the general viewer Ua by means of the general terminal  8  (S 407 ). 
     (Monitoring Information Management Program) 
     Note that the monitoring information management system and the monitoring information management method according to the present invention described above can be achieved by executing on a computer a monitoring information management program according to the present invention described in a predetermined language. That is, by installing the program according to the present embodiment in an IC chip or a memory device of a portable terminal device, a smartphone, a wearable terminal, a mobile PC, another information processing terminal, or a general-purpose computer such as a personal computer and a server computer, and executing the program on a CPU, the monitoring information management system having the above-described functions can be constructed, and the monitoring information management method according to the present invention can be implemented. 
     Specifically, by executing the above-described monitoring information management program according to the present invention on the monitoring information management server  3 , the monitoring information management server  3  functions as the position information acquisition unit  23  that specifies the current position of the surveillance camera  2 , the image capturing device information disclosure unit  312   a  that discloses the position information of the surveillance camera  2  through the communication network NW, the recorded data accumulation unit  320   c  that accumulates the recorded data in association with the position information, and the image monitoring unit  314   d  that recognizes a change in a person, an action, or an event appearing in the recorded data and that detects an abnormality appearing in the recorded data. 
     Further, by executing the monitoring information management program, the monitoring information management server  3  functions as the edit processing unit  314   a  that makes a subject appearing in the recorded data invisible and blurred, the recorded data accumulation unit  320   c  that accumulates the blurred recorded data, the restoration processing unit  314   b  that performs the restoration processing of deblurring, in a step-by-step manner, the blurred portion in the recorded data, the restoration history recording unit  314   c  that records a history of requesting or executing the restoration processing performed by the restoration processing unit  314   b  as restoration history information together with information specifying an accessor who has requested or executed the restoration processing, and the disclosed information management unit  312  that discloses the restoration history information through the communication network NW. 
     Note that the monitoring information management program according to the present invention can be distributed through a communication line, for example, and can be transferred as a packaged application that operates on a standalone computer by being recorded on a computer-readable recording medium. Specific examples of the recording medium may include a magnetic recording medium such as a flexible disk and a cassette tape, an optical disk such as a CD-ROM and a DVD-ROM, a RANI card, and various recording media. The computer-readable recording medium in which the program is recorded enables the above-described system and method to be easily implemented using a general-purpose computer or a dedicated computer, and enables the program to be easily stored, transported, and installed. 
     Modification Examples 
     Note that the embodiment described above is an example of the present invention. Therefore, the present invention is not limited to the above-described embodiment, and various modifications can be made according to design and the like without departing from the technical idea according to the present invention. 
     For example, in the above-described embodiment, the camera housing is placed on the upper surface of the support base  20  by using the support base  20  as a stationary type, but may be a hanging type as illustrated in  FIGS.  18 A and  18 B . Specifically, as illustrated in the figure, a suspension means  7  that suspends the camera housing  2 L (or  2 S) supported via the support surface  20   a  or  20   b  is used as the support base  20  described above. 
     In the present embodiment, the suspension means  7  includes a duct rail  73  suspended from the indoor ceiling surface via a flange portion  74  connected from below to a rosette  75  for power supply provided on the ceiling surface. The duct rail  73  is connected so as to be rotatable about the flange portion  74  in a horizontal plane, and a slit  73   a  is formed along the longitudinal direction at the center of the lower surface of the duct rail  73 . A cylindrical hanging ceiling portion  72  is slidably suspended from the slit  73   a  via a sliding outlet  72   a.    
     Inside the slit  73   a , a power supply rail electrically connected from the rosette  75  for power supply is laid along the longitudinal direction of the duct rail  73 , while the support base  70  is suspended below the hanging ceiling portion  72  via a universal joint  71 , and electricity is supplied from the power supply rail of the slit  73   a  to the power transmission unit  202  of the support base  70  through the sliding outlet  72   a.    
     As described above, the coils  202   a  and  202   b  are disposed and the magnet  204  is provided inside the support surface  20   a  ( 20   b ), which is the lower surface of the support surface  80 , and the camera housing  2 L (or  2 S) is attracted to the support surface  20   a  ( 20   b ) by the magnet  204 , whereby non-contact power supply can be performed. 
     (Operation and Effect) 
     According to the present embodiment, by enabling blurring of the persons and the place to be released in a step-by-step manner, the monitored image can effectively be used while the privacy of the persons captured is protected as in a case where only the behaviors of the persons can be checked without clarifying the place, in a case where, by clarifying the place and enabling the detailed behaviors of the persons to be visually recognized, the persons do not need to be specified, but the state of an accident or an incident having occurred at the place needs to be checked to some extent, or in another case, which is effective in preventing a crime and solving an incident. 
     On the other hand, in a case where the installer or the like exercises the authority to perform deblurring processing on the blurred recorded data, information about the person who has executed the deblurring processing is disclosed to an unspecified large number of the general terminals  8  through the communication network NW. Thus, the general public can constantly check through the communication network that the privacy in the image captured by the surveillance camera is not violated, and it is possible to prevent the installer of the camera from viewing the monitored image for the purpose of abuse. 
     Note that the present invention is not limited to the above-described embodiment as it is, and the components can be modified and embodied without departing from the gist thereof at the time of carrying out the invention. Also, various inventions can be formed by appropriately combining the plurality of components disclosed in the above embodiment. For example, some components may be deleted from all the components shown in the embodiment.
