 BEST MODE FOR CARRYING OUT THE INVENTION

 [0019] An information processing device, an information recording device, an information processing method, an information recording method, an information processing program, an information recording program, and a computer-readable recording medium according to the present invention will be described below with reference to the accompanying drawings. A preferred embodiment will be described in detail.

 [0020] (Embodiment)

 (Functional configuration of information processing device)

 The functional configuration of the information processing apparatus according to the present embodiment will be described with reference to FIG. FIG. 1 is a block diagram showing an example of a functional configuration of an information processing apparatus that works according to the present embodiment.

 In FIG. 1, an information processing apparatus 100 capable of communicating with a mobile body having a recording area capable of recording a series of captured video information includes a receiving unit 101, a generating unit 102, and a transmitting unit 103. The acquisition unit 104, the identification unit 105, and the force are also configured.

[0022] The receiving unit 101 receives the travel history information of the moving object. The travel history information may be, for example, information including a route traveled by the mobile body, a current location, an output value from a sensor relating to the behavior of the mobile body, and the like.

[0023] Specifically, for example, the travel history information may be received via a relay device that exists on the route through which the mobile body passes. Specifically, for example, the relay device is used for two-way short-range communication such as DSRC (Dedicated Short Range Communication). Therefore, the configuration may be such that the traveling history information on the mobile strength is relayed and the traveling history information that has been uplinked is received. Uplink refers to communication in the upward direction when looking closer to the center of the network on the communication line. Here, for example, traveling history information is transmitted to the mobile power information processing device 100. I am going to do that.

[0024] In addition, the travel history information may be received, for example, using mobile communication capable of communication at any time, and periodically receiving the travel history information uplinked by the mobile physical strength. In response to a request from device 100, uplink travel history information may be received.

[0025] In addition to the travel history information, for example, the receiving unit 101 transmits an acquisition request for video information to the specific mobile body specified by the specifying unit 105 by the transmitting unit 103 described later. As a result, it is also possible to receive video information transmitted from a specific mobile unit!

[0026] The video information may be received via a wireless communication network that can appropriately communicate with the mobile body or via a plurality of relay devices that exist on the route on which the mobile body travels. .

 In the description of FIG. 1, the video information is received by making an acquisition request to the specific mobile body, but the acquisition request is made not only to the specific mobile body but also to the mobile body. Thus, it is possible to receive the moving physical strength video information corresponding to the acquisition request. In other words, video information is acquired from a mobile body that can broadcast the acquisition request and transmit video information according to the acquisition request. In this way, video information related to the accident can be acquired simply by specifying the location and time of the accident without specifying the moving object from which the video information is to be acquired. Can be realized.

 [0028] The acquiring unit 104 acquires accident information including the location and time of the accident. Accident information may be acquired from, for example, a server (not shown) that collects accident information, or acquired by notification from a vehicle or a party that has encountered an accident.

[0029] In addition, the acquisition unit 104 may acquire accident information based on the travel history information received by the reception unit 101. Specifically, for example, when the moving body is stopped at a place where there is no possibility of stopping with reference to the travel history information, or at the same place with reference to the travel history information of a plurality of mobile bodies. When multiple moving objects stop By judging, it is also possible to acquire the location where the accident occurred and the time when the accident occurred.

 [0030] Based on the accident information acquired by the acquiring unit 104 and the travel history information received by the receiving unit 101, the specifying unit 105 specifies a moving body from which video information is to be acquired. . Specifically, for example, the specifying unit 105 specifies a specific moving body that captures video information related to an accident based on the accident information and the travel history information.

 [0031] More specifically, for example, the identifying unit 105 refers to the location and time of the accident in the accident information, and among the mobile bodies that have received the travel history information, A moving body that is traveling within a predetermined range from the point of the accident at the time of occurrence may be set as the specific moving body. In other words, it may be a configuration in which a moving body that may have acquired information related to the accident is a specific moving body.

 Transmitting section 103 transmits an acquisition request for video information recorded in the recording area to the specific mobile body specified by specifying section 105. The acquisition request is, for example, a request for transmitting video information related to an accident to the information processing apparatus 100 when the specific mobile object has recorded video information related to the accident. The acquisition request may be a request for transmitting video information corresponding to the acquisition condition, including an acquisition condition described later.

 [0033] Specifically, for example, when the specific mobile unit is configured to store the video information of the accident when the specific mobile unit overwrites and records a series of video information and encounters an accident, the specific mobile unit that has encountered the accident is stored. Request transmission of stored video information from the body. Alternatively, it is possible to request the transmission of video information before erasure in the video information related to the accident from a specific moving body overwriting the video information related to the accident while not encountering the accident.

 [0034] In addition, the transmission unit 103 transmits a recording condition generated by the generation unit 102 described later to the moving body. Specifically, for example, the transmission of the recording condition may be performed via a relay device that exists on the path through which the moving body passes after the generation unit 102 generates the recording condition.

[0035] Further, as a result of the transmission of the recording condition, the transmission unit 103 makes a request to acquire video information selected according to an acquisition condition described later from video information recorded according to the recording condition. It is good also as transmitting to a mobile body. That is, the transmission unit 103 responds to the acquisition request (including the acquisition condition) by the specific mobile unit from the video information recorded in accordance with the recording conditions for the specific mobile unit specified by the specifying unit 105. A request to acquire is sent by selecting video information.

 Based on the travel history information received by the receiving unit 101, the generation unit 102 generates an acquisition condition for video information acquired from the mobile body that is the transmission history information transmission source. The acquisition condition is a condition for selecting and acquiring video information of stored or overwritten records around the time and place where the accident occurred.

 [0037] In addition, based on the travel history information received by the reception unit 101, the generation unit 102 generates a recording condition in the recording area of the moving object that is the transmission history information transmission source. Specifically, for example, the generation unit 102 may generate a recording condition that allows video information for a longer time than the time from the occurrence of an accident to the acquisition of accident information by the acquisition unit 104 to be recorded. That is, even if the recording condition is a configuration in which the moving body performs overwriting recording of a series of video information and saves the video information of the accident when it encounters an accident, it is possible to generate the accident. Recording conditions that can overwrite and record video information for a longer time than the previous time are generated. If video information is recorded under such a recording condition, it is possible to obtain video information related to the accident that has been overwritten and recorded from a moving body that has not encountered an accident.

 [0038] In addition, the generation unit 102 may be configured to generate a recording condition that enables recording of video information having a longer time than the time required until the specific mobile unit is specified by the specifying unit 105, for example. In addition, when the generation unit 102 performs communication via the relay device, the specific mobile unit passes through the relay device that relays the communication when the acquisition unit 103 transmits the acquisition request from the specification of the specific mobile unit. It is also possible to create a recording condition that allows overwriting recording of video information for a longer time than the time required.

 [0039] (Functional configuration of information recording apparatus)

Next, the functional configuration of the information recording apparatus according to the present embodiment will be described with reference to FIG. FIG. 2 is a block diagram showing an example of a functional configuration of the information recording apparatus according to the present embodiment. In FIG. 2, an information recording apparatus 200 that records a series of video information captured from a moving body includes a receiving unit 201, a selecting unit 202, a transmitting unit 203, a setting unit 204, and a recording unit 205. And a recording medium 206.

 [0041] The receiving unit 201 receives the series of video information acquisition requests from the external server. The external server may include, for example, information related to an image to be acquired by the information processing apparatus 100 shown in FIG. 1, information related to an accident to be acquired, and the like.

 [0042] Further, the receiving unit 201 may receive recording conditions relating to a series of video information. The recording conditions may be, for example, conditions relating to the capacity and time of overwriting recording.

The selection unit 202 selects specific video information from a series of video information recorded on the recording medium 206 based on the acquisition request received by the reception unit 201. Specifically, for example, in a configuration in which a series of video information is overwritten and saved in the event of an accident, the power of the video information before overwriting and erasing or saved video information is used. The specific video information corresponding to the acquisition request is selected.

 [0044] Transmitting section 203 transmits the specific video information selected by selecting section 202 to an external server. The transmission unit 203 may transmit specific video information to an external server by a communication unit selected from the strengths of a plurality of communication units. Specifically, for example, when communication is possible with an external server using a wireless communication network, a relay device such as a beacon, etc., either the wireless communication network or the relay device is selected according to the state of receiving the acquisition request. Then, communication may be performed. In other words, if the relay device is not in the vicinity, communication may be performed using a wireless communication network, and if the relay device is in the vicinity, communication may be performed via the relay device.

 The setting unit 204 sets the recording conditions received by the receiving unit 201. The recording condition may be set, for example, by setting a recording area for overwriting recording on the recording medium 206.

The recording unit 205 records a series of video information according to the recording conditions set by the setting unit 204. For example, video information is recorded by overwriting on the recording medium 206. It may be performed in a recording area for recording.

 In the description of FIG. 2, it is assumed that video information is recorded by the recording unit 205. In addition to the video information, the travel history information of the moving body is also recorded.

 [0048] Although not described in FIG. 2, the information recording apparatus 200 transmits the traveling history information of the moving body in addition to the specific video information periodically or in response to an acquisition request from an external server. It is good to do.

 [0049] (Contents of processing of information processing apparatus)

 Next, the contents of the processing of the information processing apparatus 100 that is useful for the present embodiment will be described with reference to FIG. FIG. 3 is a flowchart showing the contents of the processing of the information processing apparatus that is relevant to the present embodiment. In the flowchart of FIG. 3, first, the receiving unit 101 determines whether or not the vehicle travel history information has been received (step S301).

Accordingly, a recording condition is generated in the recording area of the moving body that is the transmission history information transmission source (step S302).

[0051] Then, the recording unit 103 transmits the recording condition generated in step S302 (step S303). Specifically, for example, the recording condition may be transmitted via a relay device that exists on the path through which the moving object passes after the generation unit 102 generates the overwrite recording condition.

Next, the acquisition unit 104 acquires accident information including the point where the accident occurred and the time (step S304). Accident information can be obtained by, for example, a server (not shown) that collects accident information, a vehicle that has encountered an accident, a report from a party, or the travel history information received in step S301. ! / It may be a configuration to get in a hurry.

 [0053] Then, using the accident information acquired in step S304 and the travel history information received in step S301, the mobile unit that is the target of the acquisition request is specified by the specifying unit 105. (Step S305).

[0054] Next, the transmission unit 103 sets the specific mobile object specified in step S305. Then, a request for acquiring recorded video information according to the recording conditions is sent (step S

306).

 [0055] After that, as a result of the video information acquisition request being transmitted to the mobile unit in step S306 by the receiving unit 101, the video information transmitted from the mobile unit is received (step S).

307), a series of processing ends.

 It should be noted that the force information processing apparatus 100 that is not described in the flowchart of FIG. 3 may store the video information received in step S307 in a recording medium (not shown). Also, when saving the video information, the travel history information received in step S301 may be saved in association with it.

FIG. 4 is a flowchart showing the contents of processing of the information recording apparatus according to the present embodiment. In the flowchart of FIG. 4, first, the receiving unit 201 determines whether or not it has received a recording condition relating to a series of video information (step S401). For example, the recording condition may be received from a server (not shown) capable of storing video information.

 When the recording condition is received in step S401 (step S401: Yes), the setting unit 205 sets the recording condition received in step S401 (step S402). The recording condition may be set, for example, by setting a recording area in the recording medium 206. Then, a series of video information is recorded by the recording unit 205 in accordance with the recording conditions set in step S402 (step S403).

 [0059] If the recording condition is not received in step S401 (step S401: No), the process proceeds to step S403, and a series of video images according to the recording condition determined by the recording unit 205. Information is recorded (step S403). The pre-recording conditions may be set by the user, for example, by the initial setting conditions of the information recording apparatus 200.

Thereafter, the receiving unit 201 determines whether or not it has received a series of video information acquisition requests from an external server (step S404). [0061] If an acquisition request is not received in step S404 (step S404: No), the process returns to step S401 to repeat the process. If an acquisition request is received (step S404: Yes), the selection unit 202 Based on the acquisition request received in step S404, specific video information is selected from a series of video information recorded on the recording medium 206 (step S405).

 [0062] Then, the transmission unit 203 transmits the specific video information selected in step S406 to the external server (step S406), and the series of processing ends.

 [0063] As described above, according to the information processing apparatus according to the present embodiment, by requesting acquisition of video information related to an accident from a specific mobile body based on the accident information and the travel history information, Video information can be acquired. In other words, by making an acquisition request not only to a mobile body that has encountered an accident, but also to a mobile body that has captured video information related to the accident, it is possible to reliably collect video information necessary for accident verification.

 [0064] Further, by generating a recording condition of video information for imaging the moving body force and transmitting it to the moving body, the moving body can appropriately record the video information, and reliably acquire the video information related to the accident. be able to.

Accordingly, it is possible to optimize the recording of video information without determining the recording conditions by the own device.

 Example

[0068] Examples of the present invention will be described below. In this embodiment, for example, the navigation device power mounted on a moving body such as a vehicle (including a four-wheeled vehicle and a two-wheeled vehicle) is transmitted. An example in which the information processing apparatus and information recording apparatus of the present invention are implemented by a drive recorder system that communicates with an information collection server that collects information and a navigation apparatus will be described.

 [0069] (Overview of drive recorder system)

 First, the outline of the drive recorder system that works on the present embodiment will be described with reference to FIG. FIG. 5 is an explanatory diagram showing an outline of the drive recorder system according to this embodiment.

 In FIG. 5, the drive recorder system 500 includes an information collection server 501, a navigation device 502 mounted on a vehicle, and beacons 503 (503 a, 503 b, 503 c, 503 d).

 [0071] The information collection server 501 receives from the navigation device 502 a series of video information in which the vehicle force is also imaged and travel history information including output values of various sensors such as a G sensor in the vehicle and a travel history. The video information and the driving history information may be received through a beacon 503 on the route, which will be described later, or may be received from the navigation device 502 in a plurality of vehicles.

 In addition, the information collection server 501 transmits a recording condition for the navigation device 502 to overwrite and record information such as video information and travel history information to the navigation device 502, and from the navigation device 502 You can also specify the type of information to be received.

 Communication between the information collection server 501 and the navigation device 502 is performed via a beacon 503. The beacon 503 may be a two-way short-range communication infrastructure such as DSRC, and may be a relay device that an administrative agency collects vehicle travel history information and uses it for a traffic information service. By using such an infrastructure, an efficient drive recorder system 500 can be introduced.

[0074] The navigation device 502 is mounted on a vehicle and guides the vehicle to a destination point or displays the current point of the vehicle. In the present embodiment, the navigation device 502, for example, captures a series of video information by a camera, obtains travel history information including output values and travel history of various sensors such as a G sensor, and collects information via a beacon 503. Sir It is equipped with each function of communication with the 501.

 More specifically, for example, the navigation device 502 transmits video information and travel history information to the information collecting Sano 501 when passing through each beacon 503 (503a, 503b, 503c, 503d). To do. For example, video information and travel history information may be recorded according to the recording conditions transmitted from the information collection server 501 or transmitted in response to an acquisition request from the information collection server 501.

 [0076] The processing details of the information collection server 501 are described with reference to FIGS. 9 and 10, and the processing details of the navigation device 502 are described with reference to FIGS. 11 and 12. Specifically, for example, the drive recorder system 500 The information collection server 501 collects various information such as video information and travel history information from the navigation device 502 by using the beacon 503 as a two-way short-range communication infrastructure.

 [0077] Specifically, for example, the information collection server 501 is configured to be able to generate road traffic information and the like by collecting traveling history information for traveling vehicle power.

 [0078] When the information collection server 501 acquires the accident information, the information collection server 501 travels within a predetermined range from the accident occurrence point as a video information acquisition target from the collected travel history information before the accident occurrence time. The navigation device 502 mounted on the selected vehicle is identified. Here, the acquisition of accident information may be, for example, a report from the accident site or a contact from the accident party.

 [0079] Specifically, for example, the identification of the navigation device 502 from which the video information is to be acquired is based on the time force at which the accident information is acquired from the navigation device 502 that has acquired the travel history information within a predetermined time. It may be specified. Alternatively, the navigation device 502 may be specified by, for example, specifying the accident occurrence point force in the accident information from the navigation device 502 that has transmitted the travel history information via the beacon 503 installed within a predetermined distance. Good.

 In this way, if the configuration is such that the navigation device 502 to be acquired is specified by limiting the conditions without specifying from all the navigation devices 502 that are running, the processing time can be reduced and communication can be performed. The load can be reduced.

[0081] Then, the vehicle power beacon 503 in which the specified navigation device 502 is mounted is Send video request when passed. That is, the information collection server 501 makes a video request to the navigation device 502 that captures the video of the accident occurrence point and the accident occurrence time. The video request may be made, for example, when the ID (IDentifier) power assigned to the identified navigation device 502 matches the ID of the navigation device 502 passing through the beacon 503.

 [0082] The ID of the navigation device 502 may be, for example, a configuration that is set for each navigation device 502 forcibly, and each time the vehicle is driven for each NZOFF of the engine of the vehicle equipped with the navigation device 502. The configuration can be changed.

 The navigation device 502 overwrites and records video information, travel history information, and the like in a buffer memory or the like according to the overwrite recording condition transmitted from the information collection server 501. Then, each time the navigation device 502 passes under the beacon 503, the information specified by the information collection server 501 is transmitted to the information collection server 501 via the beacon 503 for the overwritten video information and travel history information. Send.

 [0132] (Overview of recording conditions)

Here, an outline of recording conditions that are useful in this embodiment will be described with reference to FIG. FIG. 8 is an explanatory diagram showing an outline of recording conditions that are useful in this embodiment. In FIG. 8, transmission / reception of various types of information between the information collection server 501 and the navigation device 502 shown in FIG. 5 will be described according to the time along the arrow 800. [0133] In FIG. 8, the vehicle equipped with the navigation device 502 is a beacon 503 shown in FIG. 5 when the arrow is pressed. [This pass.

 [0134] Time tl is the time when the accident occurred, time t2 is the time when the information collection server 501 is notified of the accident, t3 is the time when the information collection server 501 identifies the navigation device 502 from which video information is acquired, Time t4 indicates the time when the information collection server 501 makes a video request to the navigation device 502, and time t5 indicates the time when the navigation device 502 searches for video information corresponding to the video request.

 [0135] First, when a vehicle equipped with the navigation device 502 (hereinafter simply referred to as the navigation device 502) passes under the beacon 503a, the navigation device 502 provides the travel history information via the beacon 503a. Send to the collection server 501 in the direction of arrow 801.

 [0136] Then, the navigation apparatus 502 keeps the beacon 50 3b under the beacon 50 3b until the time t2 when the accident occurs at the time tl and the information collection server 501 after the time Q has received the notification of the accident after the time Q. Pass through and transmit the travel history information to the information collection Sano 501 in the direction of arrow 802 via the beacon 503b.

 [0137] When the information collection server 501 receives the notification of the accident at time t2, the information collection server 501 uses the travel history information of the navigation device 502 that has been collected so far to collect the video information at time t3 after time S2 has elapsed. The navigation device 502 to be acquired is specified.

 [0138] After that, the information collection server 501 sends the video request to the navigation device 502 via the beacon 503c through which the navigation device 502 as the acquisition target of the video information passes at time t4 after time T has elapsed from time t3. Send in the direction of arrow 803.

 [0139] When the navigation device 502 receives the video request via the beacon 503c, the navigation device 502 searches for video information temporarily recorded in a nota memory or the like, thereby requesting the video request at time t5 after the elapse of time R from time t4. The video information corresponding to is specified.

 [0140] Next, when the navigation device 502 passes the beacon 503d next, it transmits the video information corresponding to the video request to the information collection server 501 in the direction of the arrow 804 via the beacon 503d.

[0141] In this way, the information collection server 501 and the navigation device 5 follow the time indicated by the arrow 800. When transmitting and receiving various types of information to and from 02, in order to acquire the video information of the accident, a capacity that includes the accident is required in a buffer memory that temporarily records the video information by the navigation device 502.

 [0142] That is, if the video request from the information collection server 501 is immediately after the accident occurs and the beacon 503 interval is short, the navigation device 502 can acquire the video information that has been temporarily recorded without being overwritten. The video information including the accident can be transmitted to the information collecting server 01.

 [0143] On the other hand, if the video request is a long time after the occurrence of the accident or the interval between beacons 503 is long, the navigation device 502 overwrites and records the temporarily recorded video information, and The video information including the accident is deleted, and the video information cannot be transmitted to the information collection server 501.

 [0144] Therefore, the information collection server 501 transmits the capacity of a buffer memory or the like for temporarily recording video information as a recording condition to the navigation device 502, whereby the video information including the accident to be acquired becomes the navigation device. It may be prevented from being deleted by overwriting with 502.

 [0145] For example, the buffer memory for temporarily recording video information may be configured to allocate a recording area in a recording medium common to other uses, and determine the priority of allocation. By allocating the recording area in this way, the navigation apparatus 502 can efficiently perform overwriting recording of video information.

 [0146] For recording conditions in which the video information of the accident is included in the buffer memory for temporarily recording the video information, for example, the video information corresponding to the video request is specified by the navigation device 502 from the time tl when the accident occurred. Time until t5 Time P Video information may be temporarily recorded.

 [0147] As shown in Fig. 8, P can be expressed by the following equation (1).

 [0148] P = Q + S + T + R (1)

[0149] Here, time Q is the time from the occurrence of the accident at time tl to the time t2 at which the information collection server 501 receives the notification of the accident, depending on the actions of the discoverer or the party notifying the accident. It is possible to decide and set a longer time based on past cases etc. Good.

 [0150] During the time S, the information collection server 501 receives the notification of the accident at time t2, and then uses the travel history information of the navigation device 502 collected so far to obtain navigation information for which video information is to be acquired. This is the time until the time t3 when the Yon device 502 is specified, and can be estimated by the processing capability of the information collection servo 501.

 [0151] At time T, after the information collection server 501 identifies the navigation device 502 from which video information is to be acquired at time t3, the navigation device 502 from which video information is to be acquired passes the next beacon 503. This is the time up to the time t4 when the video request is received, and can be estimated by the interval of the beacon 503. Therefore, for example, the time T may set the interval of the beacons 503 on the route on which the vehicle (navigation device 502) travels.

 [0152] The time R is the time t5 when the navigation device 502 receives the video request at time t4 and then searches the video information temporarily recorded in the buffer memory to identify the video information corresponding to the video request. It can be estimated by the processing capability of the navigation device 502.

 Specifically, for example, the recording condition is that the navigation device 502 uses the communication when the navigation device 502 passes the beacon 503 to obtain the information on the time S and the time Q from the information collection server 501. Send to.

[0154] The navigation device 502 that has received the information of time S and time Q estimates the time R based on the processing capability of the navigation device 502 or past processing results.

[0155] Further, navigation device 502 calculates time T based on whether or not the current location is an area where beacons 503 are crowded. The time T may be calculated by the information collection server 501! / ヽ, for example.

[0156] The time T may be calculated based on the distance to the next beacon 503 from the interval between the beacons 503 in the map information each time the beacon 503 is passed.

[0157] In addition, before the next beacon 503 passes, if the remaining capacity of the capacity for temporarily recording video information falls below a predetermined amount, the compression rate of the video information may be increased. . [0158] By setting the recording conditions using such times P, Q, S, T, and R, the navigation device 502 can reliably temporarily record the video when the accident occurs. .

 [0160] In step S901, waiting for the acquisition of travel history information, and if acquired (step S901: Yes), the CPU 601 uses the recording to change the recording conditions of the navigation device 502. It is determined whether or not there is a condition (step S902). The recording condition to be changed may be, for example, a configuration that is performed by estimating whether or not a change has occurred in time S, time Q, and time T.

 [0161] If there is a recording condition to be changed in step S902 (step S902: Yes), the recording condition is transmitted to the navigation device 502 by communication IZF613 (step S903), and a series of recording conditions is set. The transmission process ends. The recording condition may be transmitted, for example, by transmitting change information such as the estimated time S, time Q, and time T in step S902, and the beacon 503 through which the vehicle (navigation device 502) passes. To do this.

 [0162] If there is no recording condition to be changed in step S902 (step S902: No), the process returns to step S901 and the process is repeated.

 [0163] FIG. 10 is a flowchart showing the contents of the video information storage processing procedure in the information collection server that is relevant to the present embodiment.

[0164] In step S1001, after waiting for the notification of the accident to be acquired, In step S 1002: Yes), the CPU 601 refers to the already acquired travel history information to identify the vehicle (navigation device 502) from which the video information is to be acquired (step S 1002). For example, the travel history information is acquired every time the vehicle (navigation device 502) passes the beacon 503 in step S901 shown in FIG. 9, and the information collection server 501 includes a plurality of vehicles (navigation devices 502). ) Is recorded on the V の recording medium (not shown).

 Next, a video request is transmitted by communication IZF613 to the vehicle (navigation device 502) specified in step S1002 (step S1003).

 [0166] After that, as a result of the transmission of the video request in step S1003 by communication IZF613, it is determined whether or not the video information corresponding to the video request transmitted from navigation device 502 has been acquired (step S1004). ).

 [0167] In step S1004, waiting for video information to be acquired, and if acquired (step S1004: Yes), CPU601 saves and analyzes the video information acquired in step S1004. (Step S1005), and a series of video information storage processing is completed. The analysis of the video information can be performed more accurately, for example, by the information collection server 501 instead of the navigation device 502 which may be configured to identify the cause of the accident by image recognition.

 [0168] (Contents of processing of the navigation device 502)

The acquisition of the video request may be received via a beacon 503 through which the vehicle (navigation device 502) passes, for example.

 [0172] Waiting for the acquisition of the video request in step S1201, and if it is acquired (step 7 ° S 1201: Yes), there is video information corresponding to the video request acquired in step S1201 by CPU 701. It is determined whether or not power is available (step S1202). The corresponding video information may be configured to search for video information including an accident in response to a video request from a buffer memory or a recording area for temporarily recording the video information. If the navigation device 502 can store video information, search from the recording medium in which the video information is stored.

 [0173] If there is corresponding video information in step S 1202 (step S 1202: Yes), the CPU 701 extracts the corresponding video information (step S1203).

 [0174] Also, in step S1202, if the corresponding video information is strong (step S1202: No), the series of video information transmission processing ends as it is. If the corresponding video information is strong (step S 1202: No), it may be transmitted to the information collection server 50 1 that there is no video information! /.

Then, the communication I / F 714 transmits the video information extracted in step S1203 to the information collection server 501 (step S1204), and the series of video information transmission processing ends. For example, the video information may be transmitted via a beacon 503 through which the vehicle piggybacking device 502) passes. [0176] As described above, according to the present embodiment, video information relating to an accident can be collected from a navigation device mounted on a vehicle other than the accident party. Therefore, even if the navigation device of the party is damaged, video information can be collected and the accident can be verified accurately.

 [0177] Further, if the configuration is such that video information is collected from a plurality of navigation devices, a sufficient amount of information can be secured for accident verification, and the accident verification can be optimized.

[0178] In addition, a recording condition for overwriting and recording video information can be set based on the beacon that the vehicle passes, the processing capability of the information collection server and the navigation device, and the like. Therefore, it is possible to prevent the navigation device from deleting the video information of the accident and collect the video information with certainty.

 Note that the information processing method and information recording method described in the present embodiment can be realized by executing a program prepared in advance on a computer such as a personal computer or a workstation. This program is recorded on a computer-readable recording medium such as a hard disk, a flexible disk, a CD-ROM, an MO, or a DVD, and is executed by being read by the computer. The program may be a transmission medium that can be distributed through a network such as the Internet.
