　以下、本発明の実施形態に係る携帯型防犯端末及び防犯管理装置について、図を参照して説明する。
　まず、本実施形態に係る携帯型防犯端末及び防犯管理装置を用いて提供される防犯サービス（以下、「本サービス」と称する）の概要について、図１を参照して説明する。
　本サービスは、特に子どもや老人など、防犯対策が必要とされる者を略取や誘拐、暴行といった様々な犯罪等から守ったり、そのような犯罪の早期解決を図ったりすることのできるサービスである。本サービスでは、このような犯罪から守るべき者を被監視者としてその状況を監視すると共に、被監視者の保護者等の監視者に対して被監視者の情報を提供する。 Hereinafter, a portable security terminal and a security management device according to an embodiment of the present invention will be described with reference to the drawings.
First, an outline of a crime prevention service (hereinafter referred to as “the present service”) provided by using the portable crime prevention terminal and the crime prevention management device according to the present embodiment will be described with reference to FIG.
This service can protect people who need crime prevention measures such as children and elderly people from various crimes such as predatory, kidnapping and assault, and can quickly resolve such crimes. . In this service, a person who should be protected from such a crime is monitored as a monitored person, and the status of the monitored person is provided to a monitored person such as a guardian of the monitored person.
　具体的な内容を本サービスの流れから説明すると、被監視者は携帯型防犯端末１を所持しており、この携帯型防犯端末１は、被監視者の歩行や移動といった所定の実行条件に応じて自動的に現場の撮影を開始する（Ｓ１）。携帯型防犯端末１は、撮影によって低精細画像と高精細画像の二種類の画像を生成して端末内に記憶すると共に、一定の間隔で低精細画像を防犯管理装置２に送信する（Ｓ２）。 The specific contents will be explained from the flow of this service. The monitored person possesses the portable security terminal 1, and this portable security terminal 1 responds to predetermined execution conditions such as walking and movement of the monitored person. Then, on-site shooting is automatically started (S1). The portable security terminal 1 generates two types of images, a low-definition image and a high-definition image, and stores them in the terminal, and transmits the low-definition images to the security management device 2 at regular intervals (S2). .
　監視者は、所定のウェブサイト等において被監視者が所持する携帯型防犯端末１によって生成された低精細画像を閲覧することができ（Ｓ３）、これにより被監視者の状況を把握することができる。
　さらに監視者は、気になった場面について高精細画像の閲覧を要求することができる（Ｓ４）。これに応じて、防犯管理装置２は携帯型防犯端末１に対し、監視者が要求した場面の高精細画像の取得要求を送信する（Ｓ５）。携帯型防犯端末１から防犯管理装置２に対して高精細画像が送信されると（Ｓ６）、当該高精細画像が監視者に対して閲覧可能に提供される（Ｓ７）。 The monitoring person can browse the low-definition image generated by the portable security terminal 1 possessed by the monitored person on a predetermined website or the like (S3), thereby grasping the situation of the monitored person. it can.
Furthermore, the monitor can request browsing of a high-definition image for a scene of interest (S4). In response to this, the security management device 2 transmits a request for acquiring a high-definition image of the scene requested by the supervisor to the portable security terminal 1 (S5). When the high-definition image is transmitted from the portable crime prevention terminal 1 to the crime prevention management device 2 (S6), the high-definition image is provided to the supervisor so that it can be viewed (S7).
　このように、被管理者に危険が及び得る状況にあるときや、被監視者が危険な状態にあると合理的に判断されるときなど、被監視者の状況を確認したいときに当該被監視者の状況を画像によって把握することができる。さらに、通常は低精細画像が閲覧可能に提供される一方、必要に応じて高精細画像が閲覧可能に提供されることから回線負荷が抑えられる。 In this way, when the monitored person wants to check the status of the monitored person, such as when the monitored person is in a dangerous situation or when it is reasonably determined that the monitored person is in a dangerous state, the monitored person is concerned. A person's situation can be grasped by an image. Further, normally, a low-definition image is provided so as to be viewable, while a high-definition image is provided so as to be viewable as necessary, thereby reducing the line load.
　続いて、本サービスを実現する装置及び端末の具体的な構成を詳述する。
　図２に示されるように、本実施形態においては、携帯型防犯端末１、防犯管理装置２、及び監視者端末３がインターネット等のネットワークＮＷを介して通信可能に構成されている。 Next, a specific configuration of the apparatus and terminal that realizes the service will be described in detail.

　なお、携帯型防犯端末１は、専用端末であることが好適ではあるが、スマートフォンと称されるカメラ付携帯型電話端末によって構成することも可能である。カメラ付携帯型電話端末によって構成する場合には、各機能部をアプリケーションソフトウェアとして端末に組み込むことで、カメラ付携帯型電話機を携帯型防犯端末１として機能させることができる。 The portable crime prevention terminal 1 is a terminal that is carried by a monitored person such as a child or an elderly person, and is a terminal that generates an image by photographing a scene of the scene that is useful information in the crime prevention or emergency of the monitored person.
The portable security terminal 1 includes, for example, a calculation device such as a CPU (Central Processing Unit), a computer program executed by the CPU, an internal memory such as a RAM (Random Access Memory) and a ROM (Read Only Memory), and the like. From the processing unit 11, image processing unit 12, timing unit 13, position information acquisition unit 14, recording processing unit 15, detection processing unit 16, command processing unit 17, communication processing unit 18, image storage unit 1A, and audio storage unit 1B To constitute a functional block.
In addition, although it is suitable that the portable crime prevention terminal 1 is a dedicated terminal, it can also be comprised by the portable telephone terminal with a camera called a smart phone. In the case where the mobile phone terminal with camera is configured, the functional phone is incorporated into the terminal as application software so that the mobile phone with camera can function as the mobile security terminal 1.
　撮影処理部１１は、被写体の撮影を実行する処理部であって、被写体像を撮像素子の受光面に結像させるレンズといった光学系、光学系により結像した被写体像を撮像して画像信号を制御部に出力するCMOSイメージセンサといった撮像素子、撮像素子から取得した画像信号から画像データを生成する制御部等によって構成される。
　この撮影処理部１１は、命令処理部１７から撮影の実行命令を受け付けると、２秒毎など、一定の撮影間隔で現場の撮影を自動的に実行する。 The photographing processing unit 11 is a processing unit that performs photographing of a subject, and picks up a subject image formed by an optical system such as a lens that forms a subject image on a light receiving surface of an image sensor, and an image signal. An image sensor such as a CMOS image sensor that outputs to the control unit, a control unit that generates image data from an image signal acquired from the image sensor, and the like.
When receiving an imaging execution command from the command processing unit 17, the imaging processing unit 11 automatically executes on-site imaging at regular imaging intervals such as every 2 seconds.
　なお、撮影処理部１１を構成するレンズには、広角レンズ、魚眼レンズ等、被監視者の周辺状況をより広範に捉えることのできるレンズを適宜、採用してもよい。また、暗いところでも問題なく被監視者の周辺状況を撮影きるように暗視カメラとしての機能をもたせてもよい。 In addition, as the lens constituting the imaging processing unit 11, a lens that can capture the surrounding state of the monitored person more broadly, such as a wide-angle lens and a fish-eye lens, may be appropriately employed. Further, a function as a night vision camera may be provided so that the surrounding situation of the monitored person can be photographed without any problem even in a dark place.
　画像処理部１２は、撮影処理部１１による撮影に応じて、高精細画像と低精細画像を生成する。
　この処理では例えば、所定の解像度による撮影によって高精細画像を生成すると共に、当該高精細画像のデータサイズを縮小させて低精細画像を生成する。
　また、画像処理部１２は、生成された画像データに対して画像データを識別するための画像ＩＤを発行すると共に、計時部１３によって取得された撮影時の時刻、位置情報取得部１４によって取得された撮影時の現在位置といった情報の関連付けを行う。 The image processing unit 12 generates a high-definition image and a low-definition image according to the shooting by the shooting processing unit 11.
In this process, for example, a high-definition image is generated by photographing at a predetermined resolution, and a low-definition image is generated by reducing the data size of the high-definition image.
Further, the image processing unit 12 issues an image ID for identifying the image data to the generated image data, and is acquired by the time and position information acquisition unit 14 at the time of shooting acquired by the time measuring unit 13. The information such as the current position at the time of shooting is associated.
　なお、高精細画像と低精細画像における精度あるいは解像度は相対的なものであって、予め設定された精度あるいは解像度により、データサイズの大きい高精細画像とデータサイズの小さい低精細画像の二種類の画像が生成される。 Note that the accuracy or resolution of the high-definition image and the low-definition image is relative, and two types of high-definition image with a large data size and low-definition image with a small data size are set according to preset accuracy or resolution. An image is generated.
　計時部１３は、現在時刻を計時する処理部である。
　この計時部１３により、撮影時の現在時刻を取得することで、撮影時刻が把握される。 The timer unit 13 is a processing unit that measures the current time.
The timekeeping unit 13 obtains the current time at the time of photographing, thereby grasping the photographing time.
　位置情報取得部１４は、携帯型防犯端末１の現在位置情報を取得する。
　この位置情報取得部１４は例えば、Googleが提供するFused Location ProviderといったAPIやGPS（Global Positioning System）等によって構成され、前者であれば、室内や地下空間等であってもWi-Fiの電波があれば、現在位置情報を取得することができるし、バッテリーの消費を抑えることもできる。 The position information acquisition unit 14 acquires the current position information of the portable crime prevention terminal 1.
The location information acquisition unit 14 is configured by, for example, an API such as Fused Location Provider provided by Google, GPS (Global Positioning System), and the like. In the former case, Wi-Fi radio waves can be transmitted even in indoor or underground spaces. If so, current position information can be acquired and battery consumption can be reduced.
　録音処理部１５は、マイクロホン等の集音器等により構成され、命令処理部１７から録音の実行命令を受け付けると、録音の停止命令を受け付けるまで外部音声の録音を実行する。
　また、録音処理部１５は、録音によって生成された音声データに対し、音声データを識別するための音声ＩＤを発行すると共に、計時部１３によって取得された録音開始時刻や録音終了時刻といった情報の関連付けを行う。 The recording processing unit 15 is configured by a sound collector such as a microphone. When receiving a recording execution command from the command processing unit 17, the recording processing unit 15 records external sound until a recording stop command is received.
The recording processing unit 15 issues a voice ID for identifying the voice data to the voice data generated by the recording, and associates information such as the recording start time and the recording end time acquired by the time measuring unit 13. I do.
　検出処理部１６は、携帯型防犯端末１の移動や携帯型防犯端末１に加えられた衝撃など、携帯型防犯端末１が撮影や録音を開始したり停止したりする条件となる挙動を検出する処理部である。
　この検出処理部１６は例えば、加速度センサ、回転センサ（ベクトル解析）、あるいはジャイロセンサを単独、又はこれらを組み合わせた装置によって構成される。 The detection processing unit 16 detects a behavior that is a condition for the mobile security terminal 1 to start or stop shooting or recording, such as movement of the mobile security terminal 1 or an impact applied to the mobile security terminal 1. It is a processing unit.
The detection processing unit 16 includes, for example, an acceleration sensor, a rotation sensor (vector analysis), a gyro sensor, or a device that combines these.
　命令処理部１７は、検出処理部１６によって検出された携帯型防犯端末１の挙動や位置情報取得部１４によって取得される位置情報から認識される携帯型防犯端末１の移動状況に応じて、撮影や録音の実行命令や停止命令を出す。即ち、撮影及び録音が実行されていない状況下において、所定の実行条件をトリガーとして、撮影処理部１１に対して撮影及び録音の実行を命令する。また、撮影及び録音が実行されている状況下において、所定の停止条件をトリガーとして、撮影処理部１１に対して撮影及び録音の中止を命令する。 The command processing unit 17 shoots according to the behavior of the portable security terminal 1 detected by the detection processing unit 16 and the movement status of the portable security terminal 1 recognized from the location information acquired by the location information acquisition unit 14. Or issue a recording execution or stop command. That is, in a situation where shooting and recording are not executed, the shooting processing unit 11 is instructed to execute shooting and recording using a predetermined execution condition as a trigger. Further, in a situation where shooting and recording are being performed, the shooting processing unit 11 is instructed to stop shooting and recording using a predetermined stop condition as a trigger.
　ここで、実行条件は例えば、携帯型防犯端末１の移動や携帯型防犯端末１に加えられた一定以上の外力や衝撃である。一定以上の外力や衝撃は例えば、検出処理部１６によって検出された加速度等の検出値に基づいて判断され、当該検出値が一定の閾値を超えた時には、被監視者に具体的な危険が生じたと合理的に判断できる。また、移動は例えば、歩行による移動であれば歩行固有の加速度の検出や、位置情報取得部１４によって取得された位置情報の一定時間当りの移動量に基づいて判断される。 Here, the execution condition is, for example, a movement of the portable security terminal 1 or an external force or an impact greater than a certain level applied to the portable security terminal 1. An external force or impact exceeding a certain level is determined based on, for example, a detected value such as acceleration detected by the detection processing unit 16, and when the detected value exceeds a certain threshold, a specific danger occurs to the monitored person. Can reasonably be judged. Further, for example, if the movement is a movement by walking, the movement is determined based on the detection of acceleration inherent to walking or the movement amount per certain time of the position information acquired by the position information acquisition unit 14.
　また、停止条件は例えば、実行条件を満たさなくなった後、一定時間が経過したこと等である。これにより、防犯上、監視が必要との判断によって撮影が開始された場合でも、安全性が高いと考えられる状況に落ち着いたときには危険がないものとみなして撮影を停止し、無駄にバッテリーが消費されるのを防ぐことができる。 Further, the stop condition is, for example, that a certain time has passed after the execution condition is not satisfied. As a result, even if shooting is started because it is judged that surveillance is necessary for crime prevention, when shooting is settled in a situation considered to be highly safe, shooting is considered to be dangerous, and the battery is consumed wastefully. Can be prevented.
　通信処理部１８は、インターネット等のネットワークＮＷを介して、防犯管理装置２や監視者端末３との間でデータの送受信処理を実行する機能部である。
　この通信処理部１８は、防犯管理装置２に対して、６秒毎など、撮影間隔よりも長い一定の送信間隔で低精細画像を送信する。また、防犯管理装置２からの取得要求に応じて、所定の低精細画像の撮影前の所定の時間分の高精細画像や低精細画像を送信する。 The communication processing unit 18 is a functional unit that performs data transmission / reception processing with the crime prevention management device 2 and the supervisor terminal 3 via a network NW such as the Internet.
The communication processing unit 18 transmits low-definition images to the security management device 2 at a constant transmission interval longer than the imaging interval, such as every 6 seconds.

　次に、本実施形態に係る携帯型防犯端末１、防犯管理装置２、及び監視者端末３において実行される処理の流れについて説明する。
　まず、携帯型防犯端末１において実行される低精細画像と高精細画像の生成、及び音声データの生成について、図９を参照して説明する。
　携帯型防犯端末１の検出処理部１６は常時、携帯型防犯端末１の加速度や携帯型防犯端末１に加えられる衝撃等を検出している。これに応じて命令処理部１７は、検出値が所定の閾値を超え、被監視者が歩行等の移動を始めたり、携帯型防犯端末１に衝撃が加わったりするなど、所定の実行条件を満たすか否かを判断している（Ｓ１０１）。 Next, the flow of processing executed in the portable security terminal 1, the security management device 2, and the supervisor terminal 3 according to the present embodiment will be described.
First, generation of a low-definition image and a high-definition image and generation of audio data executed in the portable security terminal 1 will be described with reference to FIG.
The detection processing unit 16 of the portable security terminal 1 always detects the acceleration of the portable security terminal 1 and the impact applied to the portable security terminal 1. In response to this, the command processing unit 17 satisfies a predetermined execution condition such that the detected value exceeds a predetermined threshold, the monitored person starts moving such as walking, or an impact is applied to the portable security terminal 1. Whether or not (S101).
　その結果、検出値が所定の閾値を超え、実行条件を満たすに至ったと判断された場合には、命令処理部１７は、撮影処理部１１に対して撮影の実行命令を出すと共に、録音処理部１５に対して録音の実行命令を出す（Ｓ１０２）。
　これに応じて撮影処理部１１が撮影処理を実行すると共に（Ｓ１０３）、録音処理部１５が録音処理を実行する（Ｓ１０４）。
　なお、録音処理及び撮影処理の詳細については後述する。 As a result, when it is determined that the detected value exceeds the predetermined threshold value and the execution condition is satisfied, the command processing unit 17 issues a shooting execution command to the shooting processing unit 11 and also records the recording processing unit. A recording execution command is issued to 15 (S102).
In response to this, the imaging processing unit 11 executes the imaging process (S103), and the recording processing unit 15 executes the recording process (S104).
Details of the recording process and the photographing process will be described later.
　録音処理及び撮影処理が実行されている間においても、検出処理部１６は、携帯型防犯端末１の加速度の変化あるいは維持、携帯型防犯端末１に加えられる衝撃等の検出を続行している。そして、これに応じて命令処理部１７は、実行条件を満たさなくなってから所定時間が過ぎ、これにより所定の停止条件を満たすに至ったか否かを判断している（Ｓ１０５）。 Even during the recording process and the photographing process, the detection processing unit 16 continues to detect or change the acceleration of the portable security terminal 1 and the impact applied to the portable security terminal 1. In response to this, the instruction processing unit 17 determines whether or not a predetermined time has passed after the execution condition is no longer satisfied, thereby determining whether or not a predetermined stop condition has been satisfied (S105).
　その結果、所定の停止条件を満たすに至ったと判断された場合には、命令処理部１７は、撮影処理部１１に対して撮影の停止命令を出すと共に、録音処理部１５に対して録音の停止命令を出す（Ｓ１０６）。
　これにより、携帯型防犯端末１における撮影及び録音が終了する。 As a result, when it is determined that the predetermined stop condition has been satisfied, the command processing unit 17 issues a shooting stop command to the shooting processing unit 11 and stops recording to the recording processing unit 15. An instruction is issued (S106).
Thereby, photographing and recording in the portable security terminal 1 are completed.
　続いて、図１０を参照して、撮影処理部１１による撮影処理の詳細について説明する。
　命令処理部１７から撮影処理の実行命令を受けた撮影処理部１１は、所定の撮影間隔に応じて撮影を行う（Ｓ２０１、Ｓ２０２）。本実施形態では、撮影間隔は２秒毎となっており、撮影処理部１１は２秒毎に撮影を行う。 Next, with reference to FIG. 10, details of the photographing process by the photographing processing unit 11 will be described.
Upon receiving the shooting processing execution command from the command processing unit 17, the shooting processing unit 11 performs shooting according to a predetermined shooting interval (S201, S202). In this embodiment, the imaging interval is every 2 seconds, and the imaging processing unit 11 performs imaging every 2 seconds.
　撮影が行われると、画像処理部１２は、高精細画像と低精細画像を生成する（Ｓ２０３）。この処理は例えば、所定の解像度による撮影によって得られた高精細画像に基づき、サイズを落とした低精細画像を生成することによって実行される。 When shooting is performed, the image processing unit 12 generates a high-definition image and a low-definition image (S203). This process is executed, for example, by generating a low-definition image with a reduced size based on a high-definition image obtained by photographing with a predetermined resolution.
　さらに、計時部１３によって撮影時刻が計時されると共に（Ｓ２０４）、位置情報取得部１４によって撮影時の現在位置に係る位置情報が取得される（Ｓ２０５）。当該撮影時刻と撮影時の位置情報は、画像処理部１２により、生成された高精細画像と低精細画像に関連付けられて、画像記憶部１Ａに記憶される（Ｓ２０６）。 Further, the time of photographing is timed by the time measuring unit 13 (S204), and the position information relating to the current position at the time of photographing is acquired by the position information acquiring unit 14 (S205). The photographing time and the positional information at the time of photographing are stored in the image storage unit 1A in association with the generated high-definition image and low-definition image by the image processing unit 12 (S206).
　撮影間隔に応じて撮影が行われるのと並行して、撮影間隔よりも長い送信間隔において、低精細画像が防犯管理装置２に送信される（Ｓ２０７、Ｓ２０８）。
　即ち、本実施形態では、送信間隔は６秒毎となっており、２秒毎の撮影によって生成された低精細画像のうち、６秒間隔に合致する低精細画像が選択的に防犯管理装置２に送信される。例えば、１８時１０分００秒から２０秒間、撮影が行われた場合、２秒間隔に該当する１８時１０分００秒、１８時１０分２秒、１８時１０分４秒、１８時１０分６秒、１８時１０分８秒、１８時１０分１０秒、１８時１０分１２秒、１８時１０分１４秒、１８時１０分１６秒、１８時１０分１８秒、１８時１０分２０秒において撮影が実行される。そして、各撮影によって生成された低精細画像のうち、６秒間隔に該当する１８時１０分００秒、１８時１０分６秒、１８時１０分１２秒、１８時１０分１８秒において生成された低精細画像が防犯管理装置２に対して送信される。 In parallel with the shooting according to the shooting interval, the low-definition image is transmitted to the security management device 2 at a transmission interval longer than the shooting interval (S207, S208).
That is, in the present embodiment, the transmission interval is every 6 seconds, and among the low-definition images generated by shooting every 2 seconds, the low-definition image that matches the 6-second interval is selectively used in the crime prevention management apparatus 2. Sent to. For example, when shooting is performed for 20 seconds from 18:10:00, 18:10:00, 18: 10: 2 seconds, 18: 10: 4, 18:10 corresponding to the 2-second interval 6 seconds, 18: 10: 8, 18:10:10, 18:10:12, 18:10:14, 18:10:16, 18:10:18, 18:10:20 Shooting is performed in seconds. Of the low-definition images generated by each shooting, the images are generated at 18:10:00, 18: 10: 6, 18:10:12, 18:10:18 corresponding to the 6-second interval. The low-definition image is transmitted to the security management device 2.
　携帯型防犯端末１から低精細画像を受信した防犯管理装置２は、被監視者の被監視者ＩＤに関連付けて、当該低精細画像を画像記憶部２Ｂに記憶する（Ｓ２０９）。
　以上の撮影処理は、撮影処理部１１が命令処理部１７から撮影の実行停止命令を受け付けるまで行われる。これにより、所定の撮影間隔で生成された高精細画像と低精細画像が携帯型防犯端末１に記憶されると共に、所定の送信間隔で携帯型防犯端末１から合板管理装置２に対して送信された低精細画像が防犯管理装置２に記憶される。 The security management device 2 that has received the low-definition image from the portable security terminal 1 stores the low-definition image in the image storage unit 2B in association with the monitored person ID of the monitored person (S209).
The above photographing process is performed until the photographing processing unit 11 receives a photographing execution stop command from the command processing unit 17. Thereby, the high-definition image and the low-definition image generated at a predetermined shooting interval are stored in the portable security terminal 1 and transmitted from the portable security terminal 1 to the plywood management device 2 at a predetermined transmission interval. The low-definition image is stored in the security management device 2.
　続いて、図１１を参照して、録音処理部１５による録音処理の詳細について説明する。
　命令処理部１７から録音処理の実行命令を受けた録音処理部１５は、外部音声を録音した音声データの生成を開始する（Ｓ３０１）。この際、計時部１３によって録音開始時刻を計時しておく（Ｓ３０２）。 Next, details of the recording process performed by the recording processing unit 15 will be described with reference to FIG.
Receiving the recording processing execution command from the command processing unit 17, the recording processing unit 15 starts generating voice data recording the external voice (S301). At this time, the recording start time is measured by the timer unit 13 (S302).
　録音は、検出処理部１６によって所定の停止条件が検出され、これに基づいて命令処理部１７から録音の停止命令が出されるまで実行される（Ｓ１０６）。
　録音処理部１５が、命令処理部１７からの停止命令に基づいて録音を終了すると、計時部１３によって録音終了時刻が計時された上（Ｓ３０３）、音声データが録音開始時刻と録音終了時刻に関連付けられて音声記憶部１Ｂに記憶される（Ｓ３０４）。 Recording is performed until a predetermined stop condition is detected by the detection processing unit 16 and a command to stop recording is issued from the command processing unit 17 based on this (S106).
When the recording processing unit 15 ends the recording based on the stop command from the command processing unit 17, the recording end time is measured by the time measuring unit 13 (S303), and the voice data is associated with the recording start time and the recording end time. And stored in the voice storage unit 1B (S304).
　生成された音声データは、携帯型防犯端末１から防犯管理装置２に対して送信され（Ｓ３０５）、これを受信した防犯管理装置２は、当該音声データを音声記憶部２Ｃに記憶する（Ｓ３０６）。
　以上の処理により、録音データが防犯管理装置２に蓄積される。 The generated voice data is transmitted from the portable security terminal 1 to the security management device 2 (S305), and the security management device 2 that has received the voice data stores the voice data in the voice storage unit 2C (S306). .
Through the above processing, the recorded data is accumulated in the crime prevention management device 2.
　続いて、監視者端末３からの閲覧要求に応じて、携帯型防犯端末１において生成された画像を当該監視者端末３に対して閲覧可能に提供する処理の流れについて、図１２を参照して説明する。
　まず、監視者は、ＩＤやパスワード等による認証処理を経て、所定の画像閲覧用のウェブサイト等から防犯管理装置２に対して、被監視者が所持する携帯型防犯端末１によって撮影された画像の閲覧要求を送信する（Ｓ４０１）。 Next, with reference to FIG. 12, a processing flow for providing an image generated in the portable security terminal 1 in a viewable manner to the supervisor terminal 3 in response to a browse request from the supervisor terminal 3 will be described. explain.
First, the monitor performs an authentication process using an ID, a password, and the like, and the image taken by the portable security terminal 1 possessed by the monitored person with respect to the security management device 2 from a predetermined image browsing website or the like. The browsing request is transmitted (S401).
　これに応じて防犯管理装置２は抽出処理部２１により、画像記憶部２Ｂを参照して、被監視者が所持する携帯型防犯端末１から受信していた低精細画像を抽出する（Ｓ４０２）。抽出された低精細画像は、一覧的に閲覧可能に監視者端末３に対して送信される（Ｓ４０３）。 In response to this, the security management device 2 uses the extraction processing unit 21 to extract the low-definition image received from the portable security terminal 1 possessed by the monitored person with reference to the image storage unit 2B (S402). The extracted low-definition image is transmitted to the supervisor terminal 3 so that it can be viewed as a list (S403).
　ここで、監視者端末３上において表示された低精細画像一覧の例を図１３に示す。
　図１３に示された閲覧画面では、一覧表示欄１０１において、画像記憶部２Ｂから抽出された低精細画像が時系列に沿って一覧的に表示されている。一覧表示された低精細画像は、防犯管理装置２が本例の送信間隔である６秒毎に携帯型防犯端末１から受信したものである。 Here, an example of a low-definition image list displayed on the supervisor terminal 3 is shown in FIG.
