Description

  The present invention relates to a disaster communication support apparatus, a disaster communication support method, and a disaster communication support program.

When a large-scale disaster occurs, the demand for important communications for the purpose of safety confirmation, damage status confirmation, evacuation instructions, etc. increases rapidly. In the Great East Japan Earthquake, communication requests were generated about 60 times in normal times in the Tohoku region and about 50 times in the 23 wards of Tokyo, and it was very difficult to provide communication services stably. In order to cope with communication requests that greatly exceed such exchange capacity, communication restrictions of up to 95% are imposed, and exchange processing is completed only at the rate of 1 call (5%) for 20 calls (communication) ) Cases of not doing so have also been reported.
Mobile communication services such as mobile phones are recognized as a part of important social infrastructure, and it is expected to provide such services stably even during a large-scale disaster. In view of this situation, the mobile phone carrier should ensure communication at the rate of one call for four calls (ie, increase the processing capacity five times) even if a communication request of an equivalent scale occurs. The goal is. We are also studying to show that a system that achieves this can be constructed and operated by dynamic communication control technology.

  On the other hand, there are two major ways of sharing disaster information and safety information. One is the idea that a government organization or a specific organization creates a mechanism that aggregates information based on the Business Continuity Plan (BCP), collects information according to the role of each organization member, and transmits it to the necessary places. This method is excellent in that target information can be efficiently collected. However, if the information collector is damaged or the server or communication means that collects information is damaged, information collection is delayed, and information beyond the information collector's collection ability cannot be collected. There is a problem of becoming insufficient. Another way of thinking is the concept of crowdsourcing, where the information user himself also plays the role of a collector. Create a mechanism to collect data in a cloud environment without depending on a specific organization or server, and information users themselves collect disaster information and safety information and upload them to the cloud environment. The information is a mechanism that anyone can refer to freely. This became possible due to the spread of social media technologies such as Twitter and Social Networking Service (SNS).

  Cloud-sourced disaster / safety information sharing using social media has been focused on and researched after the Great East Japan Earthquake. The advantage of this idea is that a lot of information is gathered quickly in large quantities. However, variations and bias in information quality are also a major drawback. In order to solve this, various cloud source-type services (systems and tools) that can be used in accordance with specific purposes have been proposed. For example, for the purpose of grasping the disaster and recovery status, there are “systems for providing disaster status and recovery status using GIS (Geographic Information System)” and “recovery and reconstruction related systems of the Local Autonomy Information Center (LASDEC)”. For example, “Google Person Finder” is famous for safety confirmation. In addition, many cloud source-type services have been proposed in fields such as support for persons requiring assistance, information transmission, shelter management, support supplies management, and life reconstruction support.

Many of these cloud source services use map information and so on, and many of them send and receive rich media data. When dynamic communication control as described above is possible, including the evacuation guidance service that has recently been proposed, voice calls that are important communications will be given priority. Therefore, a service that handles rich media content such as images may be difficult to use. In that case, it has been pointed out that services such as searching for an evacuation route in the event of a disaster that has recently been proposed cannot be used.
In the event of a disaster, obtain information to protect the user of the terminal, such as the optimal evacuation route, the situation of evacuation facilities, etc., the danger situation due to flooding or fire / collapse in various places, the operation status of transportation, drinking water, food etc. There is a need for a service that has the technology to sequentially collect and provide or view possibilities.

  During the Great East Japan Earthquake, mobile phones could not be used due to congestion and equipment shut down, and TVs and radios could not be used due to power outages, making it difficult to obtain information necessary for evacuation. In addition, due to the inability to secure an appropriate evacuation route due to traffic jams and blockage of transportation facilities, many evacuees overflowed in specific schools in urban areas and many people lost their lives due to delays in evacuation from the tsunami. In order to avoid such a situation, it is expected that new tools will be widely used in the future to help victims ensure safety.

  In Patent Literature 1, a portable terminal that transmits measurement information of outside air temperature, humidity, and wind speed to a management device via a communication network, and detection information and information that represents an activity state transmitted from the portable terminal are transmitted via the communication network. An action support system including a management device that receives the information is described.

JP2012-142000A

  However, the behavior support system described in Patent Document 1 is merely behavior support during normal times and does not consider connecting to a network during a disaster or the like. In particular, since it is not assumed that communication is congested due to congestion, such as during a large-scale disaster, the situation and location of the disaster site cannot be communicated, and the user's body is to be preserved. There is a problem that cannot be done.

  Therefore, in order to solve the above-described problem, the present invention provides a disaster communication support device, a disaster communication support method, and a disaster communication support method that can quickly transmit only important information even in a congested communication environment such as a disaster site. The purpose is to provide a disaster communication support program.

  In order to solve the above problems, a disaster communication support device according to the present invention includes a photographing unit that photographs a subject, and an importance level that includes a meaning that can identify a place or individual at the time of a disaster extracted from the photographed image information. A partial image extraction unit that acquires information of a partial image with a high level in a normal mode without communication restriction, and creates a directory in an image storage area, stores the image information in the directory, and identifies the directory name as an identification value Associating the image information with the cut out partial image, storing the image information and the partial image associated by the association, and attaching the image information or the partial image with an identification key A communication unit that transmits to the server side, a mode switching acceptance unit that accepts switching between a normal mode without communication restriction and a disaster mode with communication restriction, and the normal In mode transmits the image information and the identification key, wherein in disaster mode, characterized in that it comprises a control unit which controls transmission of the partial images and the identification key.

  Hereinafter, a mode for carrying out the present invention (referred to as “the present embodiment”) will be described in detail with reference to the drawings. Further, in all the drawings for explaining the present embodiment, the same parts are denoted by the same reference numerals in principle, and the repeated explanation thereof is omitted.

(Background explanation)
In the event of a disaster, it is important that terminal users can sequentially collect information to protect themselves. Information to protect oneself includes, for example, the optimal evacuation route, the situation of evacuation facilities, the danger situation due to flooding, fire, collapse, etc., the availability of transportation, availability of drinking water, food, etc. There are images with position information and time information. Further, it was recognized that a service having a technology for providing or browsing the information is necessary at the time of a disaster.

In the present invention, a smart phone or the like is assumed as an input terminal, and information can be directly input from a screen.
In addition, when uploading information to the server, in consideration of communication congestion, rich media communication is given priority when voice communication, which is important communication, is prioritized by dynamic control of network resources when the communication environment is deteriorated. May be suppressed. In such a case, a partial image including important information is extracted from the image information and transmitted first, and the image associated with each of the partial image information transmitted earlier when the communication environment is restored. The amount of transmission data is reduced by means of transmitting. This makes it possible to collect information that is effective even in an environment of congestion and communication control.
An image compression technique such as JPEG is used as a technique for reducing the amount of transmitted / received data. However, the data reduction ratio is about 1/10 to 1/20, and when communication restrictions of rich media restriction occur, it is considered that transmission / reception cannot be performed with this amount of data reduction.

(Cognitive media sharing technology)
The disaster communication support device can be applied to an information communication device using a cognitive media sharing technology (hereinafter referred to as CMS).
Rich media (data with a large capacity) such as images includes important information and relatively unimportant information for human use. For example, information including meanings such as company names and individual names is important information. On the other hand, the character area and the image area of the face portion have a medium importance level, and the raster data of the background area of the photograph is not so important information. Extract features from rich media content such as images, video, audio, etc. according to the meaning (partial information extraction, indexing, digesting, etc.) and convert it into structured media information without changing the utility value The amount of data can be significantly reduced. By extracting a partial image including a name, a company name, etc. from about 1 MB of the image, it is possible to reduce it to 1/50 to 1/1000.

  What is important when applying CMS to information communication devices is the recognition of the communication environment and the control of the amount of information transmitted. In Japan, the communication environment such as a telephone network is extremely stable during normal times, but the communication environment in a major disaster or in developing countries may be unstable. Detecting this situation, all content data is transmitted and received during normal times and stored in the database of the server. On the other hand, when the communication environment is unstable due to congestion, etc., only structured important data is sent and received and stored in the database, and when the communication environment is restored, all the original content data is sent and received again to the database. The technology of linking with the important data stored is important. In other words, this technology is based on the idea that priority is given to data to be transmitted / received depending on the communication environment, and transmission / reception of all content data is accomplished with a time range. As a result, even if the communication environment is unstable, only important information can be shared immediately.

(Flexible allocation of network resources using dynamic communication control technology)
FIG. 1 is a diagram for explaining flexible allocation of network resources by dynamic communication control technology. FIG. 1 shows an image of flexible allocation of network resources from a normal time to a disaster performed by a mobile phone carrier.
As shown in FIG. 1, the information communicated through the network includes files such as voice calls, mails, music, images, and moving images in the order of important communication. Music, images, videos, and files can be collectively referred to as rich media communications. Of these, voice calls and e-mails (especially voice calls) were recognized as important communications during disasters.
During normal times, that is, during normal traffic, voice calls, e-mails, music, images, videos, and files can be communicated and distributed by transportation such as fixed / mobile phone operators, networks using the Internet, transportation, etc. .
During a disaster, the communication volume is limited by damage to the communication network itself, occurrence of congestion, and congestion control. At the time of a large-scale disaster such as the Great East Japan Earthquake, it is more serious. As shown in FIG. 1, in the event of a disaster, it becomes difficult to use rich media communication services such as map search and image search via the Internet or the like.

Therefore, the bandwidth allocated to rich media communication such as music, images, and moving pictures in normal times is allocated to important communication such as voice calls and emails in the event of a disaster. As a result, important communications such as voice calls are ensured in the event of a disaster, but rich media communication services such as map search and image search via the Internet and the like that can be used during normal times become difficult to use during a disaster.
In the event of a disaster, ensuring the operation of a service for a disaster that makes heavy use of rich media communication data becomes a challenge due to the occurrence of congestion and the reduction of the rich media communication allocated bandwidth by congestion control.

(Transmission / reception data volume control on the application side according to the congestion status of the communication path)
Using the CMS, transmission / reception data amount control on the application side according to the congestion status of the communication path is performed. Note that the application of CMS is an example, and any method may be used as long as transmission / reception data amount control is performed according to the congestion status of the communication path.
The following can be considered as components of the CMS.
1. 1. Content recognition and structuring 2. Communication environment recognition and information transfer control User awareness and access control

<Content recognition and structuring>
FIG. 2 is a diagram for explaining the relationship between the amount of data in the content by CMS and the importance.
As shown in FIG. 2, content structuring is determined from the amount of data and importance. The content is structured so that the higher the importance level, the smaller the amount of data.

FIG. 3 is a diagram for explaining image recognition and information extraction by CMS.
Rich media (data with a large capacity) such as images includes important information and relatively unimportant information for human use. In the example of FIG. 3, information including meanings such as a company name and an individual name is important information (see “Meanings”: high importance in FIG. 3 a). On the other hand, the image area of the character area and the face part has a medium importance level (see “Partial image”: medium importance level in FIG. 3b), and the raster data in the background area of the photograph is not so important information (FIG. Area ": refer to low importance).

  Features are extracted according to semantic information included in rich media content such as images, video, and audio (partial information extraction, indexing, digesting), and converted into structural media information. Feature extraction is performed by, for example, partial information extraction, index assignment, and digestion.

As shown in FIG. 3, information including meanings such as company name and personal name is high in importance, the image area of the character area and the face is in importance, and the raster data in the background area of the photograph is low in importance. Then, it is preferable that the transmission target at the time of disaster is preferentially transmitted from the one with the higher importance. In this example, the company name and personal name of FIG. 3a are preferentially transmitted. This is because the location or individual at the time of the disaster can be specified if the partial image of FIG. Thereafter, a partial image with medium to low importance is sent over a predetermined time width. It should be noted that some people do not have high importance, or the order of importance is different. However, the company name / individual name is preferable in that it can be quickly handled as a partial image having a high degree of importance including a meaning that can identify a place or an individual at the time of a disaster without adding a judgment / condition.
By converting to the structural media information described above, the amount of data can be greatly reduced without changing the utility value. In this embodiment, by extracting a name and company name from an image of about 1 MB, the image is reduced to about 100B, that is, 1/10000.

<Overview of communication environment recognition and information transfer control>
FIG. 4 is a diagram for explaining the outline of communication environment recognition and information transmission amount control.
FIG. 4A shows the content data 10 and the mobile terminal device 20 that transmits and receives the content data 10. The mobile terminal device 20 is a mobile information terminal such as a smart phone, for example, and is loaded with various applications. The configuration and operation details of the mobile terminal device 20 will be described later. The content data 10 is taken as an example of the content data 10 of FIG.
The portable terminal device 20 transmits / receives the content data 10 to / from a server connected to the network.

FIG. 4B shows content data transmission / reception and server database (DB) storage in normal times, and FIG. 4C shows content data transmission / reception and server DB storage when congestion occurs.
As shown in FIG. 4B, in the normal time, all content data 10 is transmitted and received and stored in the DB 30 of the server.
As shown in FIG. 4C, when congestion occurs, only the important content data 11 (here, name, company name, shooting date / time) is transmitted / received and stored in the DB 30. Further, when the communication environment is restored, data that has not been transmitted is transmitted and received, and both are combined and stored in the DB 30.

  In Japan, the communication environment such as a telephone network is extremely stable during normal times, but the communication environment in a major disaster or in developing countries may be unstable. The user of the mobile terminal device 20 senses this situation, transmits and receives all content data in a normal state, and stores it in the server DB 30 or the like. On the other hand, if the communication environment is unstable due to congestion or the like, only structured important data is stored. Are transmitted and received and stored in the DB 30. Then, when the communication environment is recovered, all the original content data (or data that has not been transmitted) is transmitted / received again and associated with the important data stored in the DB 30 or the like. In other words, priority is given to data to be transmitted / received according to the communication environment, and transmission / reception of all content data is accomplished with a range of time. As a result, even if the communication environment is unstable, only important information can be shared immediately.

FIG. 5 is a diagram illustrating an operation mode of the mobile terminal device 20 that transmits and receives the content data 10.
As shown in FIG. 5, the mobile terminal device 20 implements two modes, a normal mode and a disaster mode. In the normal mode, a large amount of data is transmitted and received, and all data of the rich media content can be used. In disaster mode, the amount of data sent and received is small, and important and necessary data is utilized by CMS.

FIG. 6 is a diagram for explaining the background traffic, operation mode, and service use in each scene. Here, service use is transmission / reception of content data.
As shown in FIG. 6, in normal times, the background traffic is small, the operation mode is the normal mode (see FIG. 5), and the service can be used. When congestion occurs and the operation mode is the normal mode, the background traffic is large and the service usage is unstable. However, when congestion occurs and the operation mode is the disaster mode, the background traffic is large and the service can be used. In other words, even if the background traffic is large when congestion occurs, service use becomes available when the mobile terminal device 20 shifts to the disaster mode. As a result, even if the communication environment is unstable, only important information can be shared immediately.

<Description of normal mode and disaster mode>
In order to avoid excessive communication congestion due to disasters, telecommunications carriers must perform appropriate communication regulation (traffic control) on the equipment in the area (the affected area in the event of a disaster). Protect equipment and secure critical communications. Here, the communication restriction is a restriction applied when the predetermined communication amount is exceeded with respect to the normal communication and when the predetermined communication amount is finished with respect to the exchange capacity. Congestion is indicated by a phenomenon or the like when a call (response) to a call (transmission) is a predetermined value or less.
Communication restrictions include automatic regulation and manual regulation that is artificially performed according to the traffic volume in order to prevent system down. In the event of a disaster such as an earthquake, transmissions are concentrated at multiple radio base stations, and safety confirmation calls and emails are concentrated in the affected areas from all over the country. In this case, the telecommunications carrier regulates communication by combining the following methods according to the congestion state.
・ Transmission restrictions at base stations (voice and packet communications)
・ Restricting outgoing / incoming calls at switching facilities (voice and packet communications)
-SMS (Short Message Service) regulations such as new email notifications

In addition, telecommunications carriers are obliged to ensure important communications in the event of a disaster based on the provisions of the Telecommunications Business Law. However, it is difficult for a telecommunications carrier to determine that each communication is “communication including contents necessary for relief”. For this reason, important communication is secured by preliminarily setting a disaster priority telephone and preferentially handling communications originated from the disaster priority telephone.
Congestion may occur not only in the wireless section between the mobile terminal and the wireless base station, but also in the infrastructure network portion. Among the communication restrictions, the communication restriction in the wireless section is called “transmission restriction”.
Even at events such as concerts and fireworks festivals, communication traffic is concentrated in a specific narrow area, so that transmission restriction can be performed at the radio base station.

  From the above, congestion indicates a phenomenon in which communication gathers at one place and is crowded, and generally a disaster or the like is a cause. However, the event can also be a cause of occurrence. The communication regulation is a measure taken by the telecommunications carrier to cope with this congestion, and it is up to the telecommunications carrier to determine when to activate the communication regulation. Accordingly, there is a case where there is no communication restriction even at the time of congestion, and there is a case where communication restriction (transmission restriction) is performed even though there is no overall congestion. Furthermore, it is considered that it is difficult for a user such as a mobile phone to accurately know that his / her communication environment is in a congested state and that outgoing call regulation is being performed.

  Therefore, in this specification, when the user determines that there is communication restriction and operates the operation key of the mode switching reception unit 111c, the mode is shifted to “disaster mode”. Further, when the mobile terminal device 20 is equipped with an application that takes in “disaster mode” transition information and is executing it, the mobile terminal device 20 automatically transitions to the “disaster mode”. In the former case, since it is based on user judgment, it is possible to shift to the “disaster mode” without necessarily recognizing the presence and level of congestion. For this reason, there is an advantage that it is possible to shift to the “disaster mode” even when a disaster is not recognized or cannot be recognized.

The “disaster mode” referred to in the claims refers to a mode that shifts from the normal mode by user operation or notification from the telecommunications carrier when executing the corresponding application, and the “normal mode” refers to the “ It shall mean a mode that is not a “disaster mode”. For this reason, at the time of switching between the modes, it does not matter whether it is in a congested state and whether or not there is a communication restriction (transmission restriction).
The “disaster mode” and “normal mode” in the claims are as described above. The “normal mode” mainly assumes a case where there is no communication restriction (including a case where there is no or no communication) and no congestion occurs. In addition, the “disaster mode” is mainly assumed to be established either during congestion or when there is communication restriction.

FIG. 7 is a diagram for explaining the relationship between the propagation path (congestion state) and the time difference / data amount. FIG. 7 illustrates the situation of the mobile communication network at the time of the Great East Japan Earthquake.
As shown in FIG. 7, in the Great East Japan Earthquake, after the occurrence of the earthquake, extremely strong congestion continued for about 6 to 10 hours. After the earthquake occurred 3/11 14:46, transmission was restricted twice, 3/11 15: 00-3 / 12 14:00 and 3/12 18: 00-3 / 13 01:00. Converting from the call ratio and call restriction rate at 13:00 and 15:00 just before the earthquake, it is estimated that about 60 times of traffic was generated for outgoing calls and about 40 for incoming calls. In order to cope with communication requests that greatly exceed the switching capacity, communication restrictions of up to 95% are imposed, and switching processing is completed (communication) only at the rate of 1 call (5%) for 20 calls. It is estimated that

FIG. 8 is a diagram for explaining a cloud source disaster information visualization service.
As shown in FIG. 8, in the cloud source type disaster information visualization service, the user of the mobile terminal device 20 freely provides information to the disaster information server 40 placed in a cloud environment that administers administrative agencies and public services. Can be uploaded and searched. The user records disaster events that he / she experienced and takes photos to register information.

(Principle explanation)
When communication is congested, network resources are dynamically controlled, and if important communication such as voice is given priority, it becomes difficult to send an image with a large amount of data.
Therefore, the present invention cuts out a partial image including important information (for example, character information of a shelter signboard) in the image, and transmits the image with a greatly reduced data amount. The partial images collected in this way are released together with hazard maps provided by government agencies and information on victims in evacuation shelters, etc. so that users themselves can be safe and search for important people such as family members. It is used as information when doing.

FIG. 9 is a diagram for explaining the reduction in the amount of image data and the transmission of a cutout image by partial image cutout.
As shown in FIG. 9A, the information 41 including the character area is important information in the image information 40. As shown in FIG. 9B, the image information 40 taken by the user is congested. During normal times, all information is sent to a server on the cloud and stored in the database 50 of this server.

As shown in FIG. 9C, when congestion or important communication priority control corresponding to the congestion is performed due to a large-scale disaster or the like, the mobile terminal device 20 (see FIG. 8) displays a partial image (here, a character region). ). As shown in FIG. 9D, the character area 42 of “evacuation place” and “XX elementary school” is extracted from the image information 40 as important information, and “evacuation place” and “XX elementary school” are further selected. . As shown in FIG. 9E, only partial image data including important information is transmitted to the server and stored in the database 50. At this time, identification information indicating the relationship with the original image is also stored in the database 50 of the server. When the communication status is improved, the original image is also transmitted to the server, and is connected to the partial image information and held in the server.
As shown in FIG. 9 (f), the information referer refers to information (partial image (character area 42) or original mapped to the map information stored in advance in the mobile terminal device 20 according to the communication status. All image information 40) can be referred to.

Hereinafter, an operation of the disaster communication support system 100 configured as described above will be described.
First, a partial image / whole image management method of this embodiment will be described.

<Overview>
Partial images are handled only in the disaster mode. In the disaster mode, only the partial image is transmitted, and the entire image is held in the mobile terminal device 110.
When the application operation mode is switched from the disaster mode to the normal mode, the entire image is uploaded to the server side.
Data consistency is secured by an identification key (KEY) issued on the mobile terminal device 110 side.

<Disaster mode>
FIG. 12 is a diagram for explaining management of partial images and whole images in the disaster mode. FIG. 12A shows a management table 200 stored in the data storage unit 112a on the mobile terminal device 110 side and an outline of the processing. (B) shows the management table 210 stored in the data storage unit 172 on the application server 170 side and its processing outline.
As shown in FIG. 12 (a), on the terminal side,
(1) Issue an identification key and upload the partial image to the server.
(2) Register the storage location of the entire image together with the identification key as unuploaded data in the management table.

The terminal-side management table 200 attaches identification keys (KEY1, KEY2,...) To the entire image (XX.jpg, xx.jpg,...) Path and manages unuploaded data. One record is created for each post.
As shown in FIG. 12B, on the server side,
(1) The identification key and the partial image transmitted from the mobile terminal device 110 side are stored in the data storage unit 172.
(2) Since the entire image is not transmitted, nothing is registered in the entire image.
The server-side management table 210 associates the entire image (part XX.jpg, part xx.jpg,...) With the entire image for each identification key (KEY1, KEY2,...) And manages all registered data. Data consistency is ensured by an identification key issued on the mobile terminal device 110 side.

<Switch from disaster mode to normal mode>
FIG. 13 is a diagram for explaining management of partial images and entire images when switching from the disaster mode to the normal mode. FIG. 13A is a management table 200 stored in the data storage unit 112a on the mobile terminal device 110 side. And the processing outline. (B) shows the management table 210 stored in the data storage unit 172 on the application server 170 side and its processing outline.
The following processing is executed only in the normal mode. In the normal mode, no record is registered in the terminal side management table 200.

As shown in FIG. 13 (a), on the terminal side,
(1) Referring to the terminal-side management table 200, check the entire image for the unuploaded. If data is registered in the management table, upload the data to the server side.
The terminal-side management table 200 immediately after the switching attaches an identification key (KEY1, KEY2,...) To the entire image (XX.jpg, xx.jpg,...) Path and manages unuploaded data. In this case, each record is unuploaded data.
(2) KEY1: Upload to the server as XXX.jpg
(3) Upon receiving a notification that the processing has been completed normally from the server side, the corresponding record is deleted from the terminal-side management table 200.

At the time of uploading, the management table 200 on the terminal side is referred to, and KEY1: OO.jpg is uploaded from the terminal side to the server side (see the right arrow in FIG. 13). On the other hand, the terminal side receives a data reception notification from the server side (see the left arrow in FIG. 13).
The above steps (2) to (3) are repeated until there are no more records (unuploaded data) in the terminal side management table 200.

On the other hand, as shown in FIG.
(1) Do nothing until a request for registration of the entire image is received from the terminal.
The server-side management table 210 immediately after the switching associates the entire image (part XX.jpg, part XX.jpg,...) With the entire image for each identification key (KEY1, KEY2,...), And stores all registered data. to manage.
(2) Based on the request from the terminal side, the transmitted identification key is compared with the identification key of the server side management table 210, and OO.jpg is registered in the matching whole image.
(3) A notification that data has been successfully received is returned to the terminal.

  In the upload-side server-side management table 210, the part XX.jpg of the identification key 1 is uploaded to XX.jpg by KEY1: XX.jpg upload from the terminal side to the server side.

<Supplementary explanation for managing partial and whole images>
As described above, data consistency is ensured by the identification key issued on the mobile terminal device 110 side. On the application server 170 side, the entire image and the partial image can be managed based on the identification key received from the mobile terminal device 110 side to maintain consistency.
Integration of the whole image and the partial image is as follows. That is, the integration condition is integrated when the identification key assigned to the partial image and the identification key assigned to the entire image are the same. The whole image and the partial image are not physically integrated but logically integrated. Since they are logical integration, they are stored in the same record. This embodiment is characterized in that both the entire image and the partial image have the same identification key.

  Also, in the extraction of partial images, all the candidates that humans would judge to be “character strings” were extracted from the original image to be extracted, and the region was enclosed in a frame. It is displayed on the screen of the mobile terminal device 110 in a state. Although the extracted area is an area including “character string-likeness”, since the processing by the control unit 111 (see FIG. 11) is also limited, all of the displayed partial image areas are not necessarily character string areas. Not necessarily. In some cases, a region of an object such as a person or a tree may be enclosed by a frame. In that sense, it is inevitable that the partial image extracted by the original image as a target fluctuates greatly.

  In order to cope with this, in the present embodiment, among the extracted partial image areas, the user is allowed to select an area that is determined to be important (information to be transmitted). For example, as a contrivance when the user selects the extracted partial image, by changing the color of the frame surrounding the partial image area before and after selection by touching the screen of the touch panel 115 of the mobile terminal device 110, The user is informed of which partial image area is selected.

  By the way, the difference between the case where the whole image is sent from the beginning and the case where the partial image is collected and the whole image is sent will be described. Basically, there is no significant distinction between sending the whole image from the beginning and sending the whole image after collecting the partial images. However, if the entire image is sent during congestion due to a disaster (communication restriction), transmission is not completed due to congestion of the communication path, and there is a high possibility of a transmission error (timeout) at the terminal. On the other hand, when the partial image is transmitted on the terminal side in the disaster mode, there is a high possibility that the transmission is completed because the data amount is relatively small. In this case, since the disaster information image stored in the application server 170 is a partial image, only the partial image can be referred to at the time of reference. Although information on the entire image cannot be obtained, it is expected that the convenience of the user will be higher than when no information is obtained.

FIG. 14 is a diagram for explaining the operation state of the disaster communication support system 100. The same components as those in FIGS. 10 and 11 are denoted by the same reference numerals. FIG. 14 is illustrated for explaining the operation, and the control unit 111 and the like are omitted.
Step S1;
An image is captured by the camera 116 (image input device) of the mobile terminal device 110. An image photographed by the camera 116 is linked to the directory as a G1 through the data storage device 112a and stored with a unique identification ID in the terminal. At this time, the identification information K1 and the image directory information G1 are linked and stored in the data storage device 112a.

Step S2;
The partial image extraction unit 111a extracts an important image region such as character information as a partial image from the image stored in the data storage device 112a.

Step S3;
The partial image extraction unit 111a associates the partial image with the identification information K1 and the directory information M1 of the partial image, and stores the partial image in the data storage device 112a. When a plurality of images are taken, they are stored as K2, G2, M2,... Kx, Gx, Mx.

Steps S4 and S5;
When the operator performs an operation for uploading disaster information (step S4), the identification is made when the mode set based on the presence or absence of communication restriction in the mobile terminal device 110 is the disaster mode. The information Kx, the partial image Mx (image main body), and additional information Px such as image shooting time and position information are combined and transmitted to the application server 170 (disaster information database) (step S5). The disaster mode is a mode that indicates that dynamic control of the mobile communication network such as communication regulation is being performed without particularly identifying a disaster.
Here, when the user of the mobile terminal device 110 refers to the disaster information uploaded by others, all the image information uploaded by the operation of referring to the information on the server can be browsed.

Step S6;
Data received on the application server 170 side is stored in the data storage unit 172 in association with Kx, Mx, and Px.

Step S7;
The partial image selected from all the uploaded image information and the additional information are received by the terminal using the identification information Kx.

Step S8;
The selected partial image and additional information are displayed on the LCD display unit 114 (image output device).

Step S9;
When the mode of the mobile terminal device 110 is a normal mode in which communication restriction is not performed, when an image upload operation from the user of the mobile terminal device 110 to the server is performed, the original image information is included in the identification information Kx. Information associated with Gx (image body) and additional information is read from the data storage device 112a.

Step S10;
The portable terminal device 110 transmits information obtained by associating the original image information Gx (image main body) and additional information to the identification information Kx read from the data storage device 112a to the application server 170.

Step S11;
The application server 170 refers to the identification information Kx, and if partial image information Mx or Px associated with Kx already exists, the application server 170 stores the partial image information Mx or Px in association with them in the image storage directory. When there is no associated partial image information, it is stored as a new data record.

Step S12;
In the normal mode, when a request for referring to the image and disaster information is issued from the user of the mobile terminal device 110, the application server 170 transmits an image and additional information that match the identification information of the requested image. .

Step S8;
The mobile terminal device 110 outputs the received image and additional information as an image.

  As described above, the image information of the same event is separated into the original image and the partial image and held on the mobile terminal device 110 side and the application server 170 side. Each information transmission itself is divided into two modes, disaster and normal, and finally when the communication environment is stable (no congestion or communication restrictions). Combined and used as the same information. By such a mechanism, sharing of the partial image and the entire image information can be realized with time.

FIG. 15 is a flowchart showing the operation of the disaster communication support system 100.
First, in step S <b> 21, the mobile terminal device 110 inputs image information (see FIG. 9) by an image input operation using the camera 116.
In step S22, the partial image extraction unit 111a of the mobile terminal device 110 cuts out a partial image (see FIG. 9 (e)) having high importance from the captured image information (see FIG. 9 (d)).
In step S23, the mobile terminal device 110 acquires an internal ID for the input image information / partial image and stores it in the data storage unit 112a.
In step S24, when the mobile terminal device 110 receives a transmission operation for uploading data to the application server 170 side, in step S25, the mode switching reception unit 111b determines whether the communication mode is normal or disaster. Here, the communication mode may be determined by pressing a normal transmission button for normal upload and a transmission button for disaster upload (during congestion) during a disaster.

When the communication mode is normal, the portable terminal device 110 transmits the identification ID and the entire image information to the application server 170 in step S26. When the communication mode is a disaster, the mobile terminal device 110 transmits the identification ID and the partial image to the application server 170 in step S27.
Hereinafter, steps S28 to S30, S34, S35, and S37 to S39 are processing steps on the application server 170 side.
In step S28, the application server 170 normally receives the identification ID and the entire image information transmitted from the mobile terminal device 110. In step S29, the application server 170 receives the identification ID and the partial image transmitted from the portable terminal device 110 at the time of a disaster.
In step S30, the application server 170 stores the received data in the data storage unit 172 (disaster information database). Then, the application server 170 transmits the information (identification ID, entire image information, and partial image) stored in the data storage unit 172 to the mobile terminal device 110.

In step S31, when the mobile terminal device 110 accepts a retransmission operation, in step S32, the mobile terminal device 110 determines whether the communication mode is normal or disaster.
If the communication mode is normal, the portable terminal device 110 transmits the identification ID and the entire image information to the application server 170 in step S33. If the communication mode is a disaster, the process ends. Alternatively, a mode in which a predetermined time is waited until the communication mode becomes normal may be used.
In step S34, the application server 170 receives the identification ID and the entire image information. In step S35, the application server 170 connects the received partial image with the identification ID and stores it in the data storage unit 172 (disaster information database). Then, the application server 170 transmits the information stored in the data storage unit 172 (image information linked to the received partial image by the identification ID) to the mobile terminal device 110.

In step S36, the mobile terminal device 110 issues a reference request to the application server 170 by operating the key input unit 113 or the touch panel 115.
In step S37, when receiving the reference request, the application server 170 determines whether the communication mode is normal or disaster.
If the communication mode is normal, the application server 170 transmits the entire image information to the mobile terminal device 110 in step S38. If the communication mode is a disaster, the application server 170 transmits the partial image to the mobile terminal device 110 in step S39.
In step S40, the mobile terminal device 110 receives the entire image information transmitted from the application server 170, and proceeds to step S42. In step S41, the mobile terminal device 110 receives the partial image transmitted from the application server 170 and proceeds to step S42. In step S42, the LCD display unit 114 of the mobile terminal device 110 receives the received image (whole image information or partial image). ) Is displayed and this flow ends.

  As described above, the disaster communication support system 100 according to the present embodiment includes the control unit 111, the storage unit 112, the key input unit 113, the LCD display unit 114, the touch panel 115, and the camera 116. A partial image extraction unit 111a that obtains information of a partial image with high significance including a meaning that can identify a place or an individual at the time of a disaster, cut out from captured image information, in a normal mode without communication restriction; A mode switching receiving unit 111b that receives switching between a normal mode without communication restriction and a disaster mode with communication restriction. The control unit 111 performs control to transmit image information and related information in the normal mode, and transmit partial image information and related information in the disaster mode. In the disaster mode, the control unit 111 reads image information and partial image information stored in association with each other, and performs control to transmit a predetermined amount of data over a predetermined time width on the time axis. As described above, the operation of the terminal application that manages the service is different between the normal time and the disaster (congestion), or the operation mode is shifted.

  With this configuration, a disaster situation server or the like on the cloud can capture only important information even if a rich media communication restriction is taken by taking a picture of the situation at the disaster site with a portable terminal (mobile terminal device 110) during a disaster. Server 170). That is, in a situation where congestion occurs due to a disaster, it is difficult to transmit an image with a large amount of data. In the present embodiment, only the important part of the image information is extracted to reduce the data amount, and the necessary minimum information sharing can be ensured. In addition, when the congestion ends, the original image can be transmitted and received to grasp the whole.

  On the disaster information server side, even at the time of a disaster, only important information including meaning can be browsed. Since the situation and location of the disaster occurrence site can be grasped, the user can be protected. In addition, since the partial image can be confirmed by linking with the original image information when the communication is stable, the ambiguity of the information can be eliminated.

  In this embodiment, since partial images and original image information are transmitted or associated with a time lag, sharing of cloud source type disaster information is possible in an environment where communication restrictions are imposed due to the occurrence of a large-scale disaster. Use as a system is expected. It is expected to be used as a service for residents by local governments and public institutions.
