  The flash ROM 104 is a memory that stores a program and data for controlling the CPU 101, for example. Also, various setting information is held.

  The RAM 105 is a work memory used in the operation of the CPU 101, for example. For example, a plurality of RAMs 105 are provided.

  The μCON 106 is, for example, a kind of microcomputer and is connected to each unit (for example, the GPS 107, the GPIO 108, the button 109, and the LED 110) related to the external interface, and performs control related to the external interface. The μCON 106 is connected to the CPU 101 via, for example, a UART (Universal Asynchronous Receiver Transmitter).

  The GPS 107 receives, for example, the current position information and time information of the in-vehicle recorder 62 from a GPS transmitter (not shown) and outputs it to the CPU 101. This time information is used for correcting the system time of the in-vehicle recorder 62.

  The GPIO 108 is, for example, a parallel interface, and inputs and outputs signals between the MCU 19 and an external device (not shown) connected via the GPIO 108. For example, various sensors (for example, a speed sensor, an acceleration sensor, and a door opening / closing sensor) are connected to the GPIO 108.

  The button 109 is, for example, a recording button for starting or stopping recording of video data imaged by the in-vehicle camera 61, and an application for adding attribute information or meta information to the video data imaged by the in-vehicle camera 61. Button.

  The LED 110 lights, turns off, and blinks, for example, a power-on state (on / off state) of the in-vehicle recorder 62, a recording state, a connection state of the in-vehicle recorder 62 to the LAN, and a use state of the LAN connected to the in-vehicle recorder 62. Etc. are displayed.

  For example, the SSD 111 stores video data captured and recorded by the in-vehicle camera 61. The SSD 111 may store video data captured and recorded by the wearable camera 10. The SSD 111 may store data other than video data. The SSD 111 is connected to the CPU 101 via SATA (Serial ATA). A plurality of SSDs 111 may be provided. A storage (for example, HDD) other than the SSD 111 may be provided.

  FIG. 9 is a block diagram illustrating an example of the internal configuration of the in-vehicle PC 63. The in-vehicle PC 63 includes a CPU 201, an I / O (Input / Output) control unit 202, a communication unit 203, a memory 204, an input unit 205, a display unit 206, a speaker 207, and an HDD 208. is there. The in-vehicle PC 63 can communicate with the wearable camera 10 and the in-vehicle recorder 62, and can also communicate with the server devices SV1 to SV3 and the in-station PC 71 of the back-end system 100B.

  For example, the CPU 201 performs control processing for overall control of the operation of each unit of the in-vehicle PC 63, input / output processing of data with other units via the I / O control unit 202, and calculation (calculation) of data. Processing and data storage processing are performed.

  For example, the CPU 201 authenticates whether or not the police officer 7 can log in to the in-vehicle system 60 by an input operation of the police officer 7 on a login screen (not shown) to the in-vehicle system 60 displayed on the display unit 206. The input operation of the police officer 7 is, for example, an operation of inputting an officer ID and a password. Various types of information related to the police officer 7 to whom login is permitted are stored in advance in, for example, the memory 204, and the CPU 201 uses the information on the login permission target stored in the memory 204 in advance to use the police officer 7. Whether to log in to the in-vehicle system 60 is determined.

  This login may be a login to the in-vehicle system 60 via the in-vehicle PC 63, or a login to an application for operating the in-vehicle system 60 mounted in the in-vehicle PC 63.

  The I / O control unit 202 controls data input / output between the CPU 201 and each unit of the in-vehicle PC 63 (for example, the communication unit 203, the input unit 205, the display unit 206, and the speaker 207). Relay data to. The I / O control unit 202 may be configured integrally with the CPU 201.

  The communication unit 203 performs wired or wireless communication with, for example, the in-vehicle recorder 62, the wearable camera 10 that can be worn by the police officer 7, or the back-end system 100B side.

  When the police officer 7 is logging in to the in-vehicle system 60, the communication unit 203 transfers and copies the login information stored in the memory 204 to the wearable camera 10, and the police officer 7 has not logged in to the in-vehicle system 60. The login information is not transferred to the wearable camera 10.

  The login information includes, for example, an Office ID for identifying the police officer 7, a Camera ID for identifying the wearable camera 10, and a Car ID for identifying the police car 6 to be used.

  The memory 204 is configured using, for example, RAM, ROM, nonvolatile or volatile semiconductor memory, functions as a work memory when the CPU 201 operates, and stores a predetermined program and data for operating the CPU 201. . The memory 204 stores, for example, login information related to the police officer 7 who is permitted to log in to the in-vehicle system 60.

  The input unit 205 is a UI for receiving an input operation of the police officer 7 and notifying the CPU 201 via the I / O control unit 202, and is a pointing device such as a mouse or a keyboard. The input unit 205 may be configured using, for example, a touch panel or a touch pad that is arranged corresponding to the screen of the display unit 206 and can be operated with a finger of the police officer 7 or a stylus pen.

  The input unit 205 inputs login information for logging in to the in-vehicle system 60, for example.

  The display unit 206 is configured using, for example, an LCD (Liquid Crystal Display) or an organic EL (Electroluminescence), and displays various types of information. The display unit 206 is included in the video data under the instruction of the CPU 201 when video data captured (recorded) by the wearable camera 10 is input in response to an input operation of the police officer 7, for example. Display video on the screen.

  The speaker 207 is included in the video data under the instruction of the CPU 201 when video data including sound captured (recorded) by the wearable camera 10 is input in response to an input operation of the police officer 7, for example. Output audio. The display unit 206 and the speaker 207 may be configured separately from the in-vehicle PC 63.

  The HDD 208 stores, for example, various data and software (software program). Specifically, the HDD 208 stores, for example, software for controlling and setting the in-vehicle recorder 62 and software for controlling and setting the wearable camera 10. Further, the HDD 208 stores video data transferred from the wearable camera 10 and captured by the wearable camera 10, for example.

  Next, giving attribute information to video data will be described.

  Assume that wearable camera system 100 uses video data recorded by wearable camera 10, transferred to servers SV1 to SV3, and stored. Similarly, it is assumed that video data captured by the in-vehicle camera 61, recorded by the in-vehicle recorder 62, transferred to the servers SV1 to SV3 and stored is used.

  In this case, for example, the in-station PC 71 receives image data such as the type of image content, the imaged police officer 7, the date and time, the imaging location, etc. from the accumulated image data in response to the operation of the police officer in the police station 5. The target video data can be extracted and reproduced based on some attribute information related to the. At this time, attribute information associated with the video data is used. By adding the attribute information to the video data, it is easy to determine what the video is captured, and it is easy to extract the target video data.

  Here, wearable camera 10 assigns classification information (Classify) indicating the type of video content as attribute information, and enables video data to be sorted into various types. The classification information indicates a case category related to the content of the video data. Giving attribute information to video data is also referred to as tagging. Note that the attribute information is not limited to the classification information, and includes any information related to the recorded video data. Moreover, the classification information as attribute information may have a hierarchical structure, for example, or may be categorized by a plurality of systems with different classifications.

  Similarly to the above, the in-vehicle recorder 62 assigns classification information (Classify) indicating the type of video content as attribute information, and enables video data to be sorted according to various types.

  FIG. 10 is a schematic diagram illustrating an example of attribute information in the wearable camera 10. This attribute information is selected by the operation of the attribute selection switch SW4 and is given by the operation of the attribute assignment switch SW3.

  When the wearable camera 10 is used, as shown in FIG. 10, attribute information is assigned and set in correspondence with the states (contact positions) C1 to C3 of the attribute selection switch SW4. In the illustrated example, it is assumed that the police officer 7 images the scene 8 (for example, the scene of the incident). (Stolen Property).

  In the assignment of attribute information, for example, the MCU 19 of the wearable camera 10 selects and sets attribute information frequently used by the police officer 7 from among a plurality of defined attribute information. The setting content of the attribute information is stored as, for example, one of the setting information in the EEPROM 16 of the wearable camera 10.

  FIG. 11 is a schematic diagram illustrating an example of attribute information in the in-vehicle recorder 62. In the in-vehicle recorder 62, for example, the communication unit 203 acquires attribute information input by the input unit 205 of the in-vehicle PC 63, and the CPU 101 acquires the acquired attribute information for the video data captured by the in-vehicle camera 61. And the attribute information is stored in the SSD 111 in association with the video data. In the attribute information assignment by the in-vehicle recorder 62, since the number of contacts is not determined as in the attribute selection switch SW4, more types of attribute information can be assigned. The attribute information is stored in association with the video data as a single piece or as meta information including the attribute information.

  As shown in FIG. 11, the police officer 7 can input, for example, any one of 11 pieces of attribute information via the in-vehicle PC 63. This attribute information includes, for example, Disorderly Conduct, drunk driving, drunkness, drug abuse, alcohol law violations (Liquir Law Violations), peeping (Peeping Tom), and trespassing of trespassing. , Theft, vandalism, weapons, and all other offenses.

  Therefore, for example, the police officer 7 can give more detailed attribute information to the video data captured by the in-vehicle camera 61 than the attribute information used by the wearable camera 10, and the attribute more suitable for the actual situation of the site 8. Information can be given.

  FIG. 12 is a schematic diagram showing an example of the data structure of the recording data. The recorded data includes recorded video data and meta information corresponding to the video data. Although the meta information will be described later, the meta information includes attribute information. The recording data captured and recorded by the wearable camera 10 and the recording data captured by the in-vehicle camera 61 and recorded by the in-vehicle recorder 62 have the same format.

  Next, the data structure of the recorded video list will be described. A recorded video list related to video data captured by the wearable camera 10 is held in the storage unit 15 of the wearable camera 10. A recorded video list relating to video data captured by the in-vehicle camera 61 is held in the SSD 111 of the in-vehicle recorder 62.

  FIG. 13 is a schematic diagram illustrating an example of a data structure of a recorded video list held by the wearable camera 10.

  When the wearable camera 10 detects an operation input of the attribute information addition switch SW3 during or after recording, the wearable camera 10 generates attribute information related to video data to be recorded, and stores meta information including the attribute information in the storage unit 15. . That is, the video recording data stored in the storage unit 15 includes video data and meta information. Wearable camera 10 transfers and accumulates recording data including video data and meta information when transferring video data to servers SV1 to SV3. Note that the video data and the meta information may be transferred separately.

  The meta information related to the video data is stored, for example, in the form of a recorded video list as shown in FIG. The meta information of the recorded video list includes video position information (video time information), Car ID, Office ID, attribute information (case category), recording start factor, and other information.

  Video data and meta information are associated with each other by a video data ID. The video data ID is identification information for identifying the recorded video data. The video data ID is given to the video data at the start of recording, during recording, or at the end of recording, for example. The video data ID includes, for example, video recording start time, file name, and other IDs.

  The video position information is time information when the meta information is added to the video data, that is, information of the time when the operation input of the attribute information addition switch SW3 is detected (also referred to as attribute information addition time).

  The Car ID is identification information for identifying each police car 6. Office ID is identification information of the police officer 7 who uses the wearable camera 10. By setting the Car ID and the Office ID, it is possible to determine which police officer 7 using which police car 6 has recorded video data using the wearable camera 10.

  The case category is classification information for identifying the type of video data, and is assigned according to the attribute selection switch SW4 based on the setting contents of the attribute information shown in FIG.

  The recording start factor indicates a factor at which video data recording is started. The recording start factors include, for example, detection of pressing of the recording switch SW1 or snapshot switch SW2, detection of a recording start trigger based on information of a sensor (not shown, for example, an acceleration sensor) provided in the wearable camera 10, RTC 17, or GPS 18, in-vehicle Including system linkage.

  The in-vehicle system linkage indicates that the in-vehicle system 60 and the wearable camera 10 cooperate and the wearable camera 10 has started recording in response to a recording start instruction from the in-vehicle recorder 62.

  Other information includes, for example, GPS information. The GPS information is position information indicating a place where video data is recorded. For example, the current position information at the time of attribute information addition is acquired from the GPS 18 and assigned.

  The meta information provided by the wearable camera 10 is provided by, for example, the processing of the MCU 19 and is stored in the storage unit 15 in association with the video data captured by the wearable camera 10.

  Although not shown in FIG. 13, one or more pieces of meta information may be assigned to one video data, that is, one video data ID. For example, when the police officer 7 encounters a scene of drug abuse while cracking down on drunk driving, the wearable camera 10 can be operated by inputting the attribute information addition switch SW3 twice or more while recording the video data. Two or more pieces of meta information can be given to one video data.

  FIG. 14 is a schematic diagram showing an example of a data structure of a recorded video list held by the in-vehicle recorder 62. As shown in FIG.

  The recorded video list held by the in-vehicle recorder 62 also includes meta information including attribute information for video data. The contents of the meta information are the same as the contents of the meta information shown in FIG.

  However, the in-vehicle recorder 62 can provide more types of attribute information (case category) than the attribute information provided by the wearable camera 10. The attribute information in the in-vehicle recorder 62 is input from the input unit 205 of the in-vehicle PC 63 and acquired from the in-vehicle PC 63, for example. Further, the in-vehicle recorder 62 detects, as information about the recording start factor, pressing of an attribute information giving button, a sensor (not shown, for example, a speed sensor, an acceleration sensor, or a door opening / closing sensor) provided in the in-vehicle system 60, RTC 17, or Including detection of a recording start trigger based on information of the GPS 107 and WCAM linkage.

  The WCAM link indicates that the in-vehicle system 60 and the wearable camera 10 cooperate with each other, and the in-vehicle camera 61 starts recording in accordance with an instruction from the in-vehicle recorder 62 in response to a recording start instruction from the wearable camera 10.

  The meta information provided by the in-vehicle recorder 62 is provided by, for example, the processing of the CPU 101, and is stored in the SSD 111 in association with video data captured by the in-vehicle camera 61.

  Next, an operation example of the wearable camera system 100 will be described.

  FIG. 15 is a sequence diagram illustrating a first example of the attribute information assigning procedure by the wearable camera system 100. In FIG. 15, it is assumed that the wearable camera 10 starts recording before the in-vehicle recorder 62 and gives the attribute information before the in-vehicle recorder 62.

  15 illustrates that the in-vehicle recorder 62 and the wearable camera 10 are wirelessly connected by a wireless LAN, but may be wirelessly connected by other methods or may be wired.

  First, the in-vehicle recorder 62 and the wearable camera 10 mutually detect communication partners, and a communication link is established between the in-vehicle recorder 62 and the wearable camera 10 (S1). Specifically, the CPU 101 of the in-vehicle recorder 62 and the MCU 19 of the wearable camera 10 detect a communication partner by performing a pairing process using, for example, a wireless LAN SSID and a password.

  In addition, the wireless communication unit 102 of the in-vehicle recorder 62 and the communication unit 21 of the wearable camera 10 exchange, for example, a Car ID and an Office ID that are held with each other, and the Car and the communication partner device hold. A communication link is established when the ID and the Office ID match.

  Note that the wireless communication unit 102 of the in-vehicle recorder 62 and the communication unit 21 of the wearable camera 10 may establish a communication link when a communication partner is detected without confirming a match between the Camera ID and the Office ID. . For example, when the police officer 7 is not logged in to the in-vehicle PC 63, the camera ID and the Office ID are not input to the in-vehicle recorder 62, and therefore the in-vehicle recorder 62 does not hold the Camera ID and the Office ID.

  Even in this case, a communication link can be established between the in-vehicle system 60 and the wearable camera 10. For example, even if the combination of the police officer 7 and the police car 6 at the time of dispatch is different every time and is not fixed, the in-vehicle recorder 62 and the wearable camera 10 can be easily connected using a wireless LAN or the like.

  In the wearable camera 10, when the MCU 19 detects a recording start trigger, the MCU 19 starts recording the video data imaged by the imaging unit 11 and starts storing the video data in the storage unit 15 (S2).

  The recording start trigger of the wearable camera 10 includes, for example, detection of pressing of the recording switch SW1 or the snapshot switch SW2 by the MCU 19, detection of disconnection of the wireless connection between the in-vehicle recorder 62 and the wearable camera 10 by the communication unit 21, and an acceleration sensor. Detection of the impact (ie, detection of a change in acceleration equal to or greater than a predetermined threshold), detection of the presence of the police officer 7 by the GPS 18 and detection of the police officer 7 starting by the GPS 18. The detection of the impact by the acceleration sensor includes, for example, detection that the police officer 7 has started running or has fallen.

  When the MCU 19 starts recording video data, the communication unit 21 notifies the in-vehicle recorder 62 as a communication partner of a recording start message (for example, a message “REC START”) including the fact that the recording has started (S3). .

  In the in-vehicle recorder 62, when the wireless communication unit 102 receives a recording start message from the in-vehicle recorder 62, the CPU 101 starts recording the video data captured by the in-vehicle camera 61 and starts storing the video data in the SSD 111. (S4).

  Thus, by starting the recording of the in-vehicle recorder 62 in cooperation with the start of recording of the wearable camera 10, for example, an incident occurs after arrival at the site 8 and the recording by the in-vehicle camera 61 in the police car 6 is started. Even if not, the video data of the site 8 can be recorded by the in-vehicle camera 61 and confirmed at a later timing.

  After the recording by the wearable camera 10 and the in-vehicle recorder 62 is started, in the wearable camera 10, when the MCU 19 detects a recording stop trigger, the MCU 19 stops recording the video data captured by the imaging unit 11, and stores the video data in the storage unit 15. The storage is stopped (S5).

  The recording stop trigger of the wearable camera 10 includes, for example, detecting operation of the recording switch SW1 by the MCU 19 during recording and detecting that a predetermined time has elapsed from the start of recording by the wearable camera 10.

  When the MCU 19 stops the recording of the video data, the communication unit 21 notifies the in-vehicle recorder 62 as a communication partner of a recording stop message (for example, “REC STOP” message) including the fact that the recording is stopped (S6). .

  In the in-vehicle recorder 62, when the wireless communication unit 102 receives a recording stop message from the wearable camera 10, the CPU 101 stops recording video data captured by the in-vehicle camera 61 and stops storing video data in the SSD 111. (S7).

  Thus, by stopping the recording of the in-vehicle recorder 62 in cooperation with the recording stop of the wearable camera 10, for example, even when the user has forgotten to press the button 109 to stop the recording, the image is captured by the in-vehicle camera 61. Recording of video data can be stopped. Therefore, unnecessary power consumption and memory consumption due to forgetting to stop recording video data can be reduced.

  15 illustrates that the wearable camera 10 stops recording and transmits a recording stop message in S5 and S6, and the in-vehicle recorder 62 receives the recording stop message and stops recording in S7. Alternatively, the in-vehicle recorder 62 may stop recording and transmit a recording stop message in S5 and S6, and the wearable camera 10 may receive the recording stop message and stop recording in S7.

  In addition, the process of S5-S7 may be abbreviate | omitted. That is, the recording stop cooperation between the wearable camera 10 and the in-vehicle recorder 62 may not be performed.

  In the wearable camera 10, after the recording is started in S <b> 2, the MCU 19 gives attribute information related to the video data to the video data captured by the imaging unit 11 and recorded by the MCU 19 (S <b> 8). In giving the attribute information, the MCU 19 stores the attribute information selected by the attribute selection switch SW4 in the storage unit 15 in association with the video data recorded by the wearable camera 10.

  When the attribute information is given by the MCU 19, the communication unit 21 notifies the in-vehicle recorder 62 as a communication partner of an attribute information message including this attribute information (S9).

  In the in-vehicle recorder 62, the wireless communication unit 102 receives an attribute information message from the wearable camera 10. Then, the CPU 101 gives the received attribute information as attribute information related to the video data to the video data captured by the in-vehicle camera 61 and recorded by the in-vehicle recorder 62 (S10). In the assignment of the attribute information, the CPU 101 stores the attribute information acquired from the wearable camera 10 (that is, the attribute information selected by the attribute selection switch SW4) in the SSD 111 in association with the video data recorded by the in-vehicle recorder 62. In addition, each video data to which the same attribute information is provided in the wearable camera 10 and the in-vehicle recorder 62 is, for example, video data recorded in the same time zone or a close time zone.

  Although FIG. 15 illustrates that the attribute information message is notified after the wearable camera 10 stops recording, the attribute information message may be notified during the recording by the wearable camera 10.

  In this way, the attribute information is given by the in-vehicle recorder 62 in cooperation with the attribute information given by the wearable camera 10, so that the police officer 7 can give the in-vehicle PC 63 the attribute information in the in-vehicle recorder 62. This saves you the trouble of inputting operations. Even in this case, the police officer 7 can easily search for necessary video data using the assigned attribute information at a later timing.

  In addition, since a plurality of pieces of meta information can be given to one piece of video data, a plurality of pieces of attribute information can be given to one piece of video data. That is, attribute information (for example, “illegal intrusion”) input via the in-vehicle PC 63 with respect to video data captured by the in-vehicle camera 61 and attribute information (for example, “theft”) according to the operation of the attribute assignment switch SW3. ) And both. Thereby, the wearable camera system 100 can determine the content of the video data with higher accuracy.

  FIG. 16 is a sequence diagram illustrating a second example of the attribute information adding procedure by the wearable camera system 100. In FIG. 16, it is assumed that wearable camera 10 starts recording before in-vehicle recorder 62 and assigns attribute information after in-vehicle recorder 62. In the operation example of FIG. 16, the same steps as those in the operation example of FIG. 15 are denoted by the same step numbers, and description thereof is omitted or simplified.

  First, wearable camera system 100 performs processing of S1-S7.

  In the in-vehicle recorder 62, after starting the recording in S4, the CPU 101 gives attribute information related to the video data to the video data captured by the in-vehicle camera 61 and recorded by the in-vehicle recorder 62 (S8A). In the assignment of the attribute information, the CPU 101 stores the attribute information input via the in-vehicle PC 63 in the SSD 111 in association with the video data recorded by the in-vehicle recorder 62.

  When the CPU 101 assigns the attribute information, the wireless communication unit 102 notifies the wearable camera 10 as a communication partner of an attribute information message including the attribute information (S9A).

  In the wearable camera 10, the communication unit 21 receives an attribute information message from the in-vehicle recorder 62. Then, the MCU 19 gives the received attribute information as attribute information related to the video data to the video data captured by the imaging unit 11 and recorded by the MCU 19 (S10A). In giving the attribute information, the MCU 19 stores the attribute information acquired from the in-vehicle recorder 62 (that is, attribute information input via the in-vehicle PC 63) in the storage unit 15 in association with the video data recorded by the wearable camera 10. Let In addition, each video data to which the same attribute information is provided in the wearable camera 10 and the in-vehicle recorder 62 is, for example, video data recorded in the same time zone or a close time zone.

  16 illustrates that the attribute information message is notified after the recording by the in-vehicle recorder 62 is stopped, but the attribute information message may be notified during the recording by the in-vehicle recorder 62.

  In this way, attribute information other than the attribute information assigned to the attribute selection switch SW4 can be given by giving attribute information by the wearable camera 10 in cooperation with the attribute information given by the in-vehicle recorder 62, and the wearable camera 10 Attribute information can be extended with Further, since the in-vehicle recorder 62 can give more types of attribute information than the wearable camera 10, the case content at the site 8 does not match the attribute information at the wearable camera 10 or the attribute information at the wearable camera 10. Even when the details cannot be shown, the relevance between the case contents and the attribute information given can be enhanced.

  In addition, since a plurality of pieces of meta information can be given to one piece of video data, a plurality of pieces of attribute information can be given to one piece of video data. For video data captured by the wearable camera 10, attribute information (for example, “drinking driving”) according to the operation of the attribute assignment switch SW3, and attribute information (for example, “destruction of public objects”) input via the in-vehicle PC 63. ) And both. Thereby, the wearable camera system 100 can determine the content of the video data with higher accuracy. Further, the attribute information of both of the above may not be provided, and the attribute information provided by the operation of the attribute assignment switch SW3 may be replaced with the attribute information input via the in-vehicle PC 63.

  FIG. 17 is a sequence diagram illustrating a third example of the attribute information assigning procedure by the wearable camera system 100. In FIG. 17, it is assumed that wearable camera 10 starts recording after in-vehicle recorder 62 and assigns attribute information after in-vehicle recorder 62. In the operation example of FIG. 17, processes similar to those in the operation example of FIG. 15 or FIG. 16 are denoted by the same step numbers, and description thereof is omitted or simplified.

  First, the wearable camera system 100 performs the process of S1.

  In the in-vehicle recorder 62, when the CPU 101 detects a recording start trigger, it starts recording the video data imaged by the in-vehicle camera 61 and starts storing the video data in the SSD 111 (S2B).

  The recording start trigger of the in-vehicle recorder 62 is, for example, detection of pressing of the button 109, detection of the start of lighting of the patrol lamp of the police car 6 by the CPU 101, and the traveling speed of the police car 6 by the speed sensor is a predetermined speed (for example, 100 km / h) or more Detection of impact, detection of an impact by an acceleration sensor (that is, detection of a change in acceleration equal to or greater than a predetermined threshold value), and detection that the wireless communication unit 102 is out of a communication area where communication with the wearable camera 10 is impossible.

  When the CPU 101 starts recording video data, the wireless communication unit 102 notifies the wearable camera 10 as a communication partner of a recording start message (for example, a message “REC START”) including the fact that recording has started (S3B). ).

  In the wearable camera 10, when the communication unit 21 receives the recording start message from the in-vehicle recorder 62, the MCU 19 starts recording the video data captured by the imaging unit 11 and starts storing the video data in the storage unit 15. (S4B).

  In this way, by starting the recording of the wearable camera 10 in cooperation with the start of recording of the in-vehicle recorder 62, for example, the police officer 7 performs the recording by the recording switch SW1 or the snapshot switch SW2 of the wearable camera 10 for emergency response. Even if the start operation is forgotten, the video data of the site 8 can be recorded and confirmed at a later timing.

  When the recording start trigger is detected, the in-vehicle recorder 62, for example, if the distance between the in-vehicle recorder 62 and the wearable camera 10 is long and out of the communication range by the wireless LAN, the recording start message is returned after the wireless connection is restored. You may send it.

  Wearable camera 10 may not start recording immediately after receiving the recording start message. For example, the wearable camera 10 does not start recording when it receives a recording start message while the police car 6 is running, and when it detects that the wireless connection with the in-vehicle recorder 62 has been disconnected after leaving the police car 6, You may start. Thereby, the resource of the memory | storage part 15 which accumulate | stores the recorded video data can be used efficiently.

  After the start of recording by the in-vehicle recorder 62 and the wearable camera 10, in the in-vehicle recorder 62, when detecting the recording stop trigger, the CPU 101 stops recording of the video data captured by the in-vehicle camera 61 and stores the video data in the SSD 111. Stop (S5B).

  The recording stop trigger of the in-vehicle recorder 62 includes, for example, detection of pressing of the button 109 by the CPU 101 during recording, and detection of a predetermined time from the start of recording by the in-vehicle recorder 62.

  When the CPU 101 stops the recording of the video data, the wireless communication unit 102 notifies the wearable camera 10 as the communication partner of a recording stop message (for example, a message “REC STOP”) including the fact that the recording is stopped (S6B). ).

  In the wearable camera 10, when the communication unit 21 receives a recording stop message from the in-vehicle recorder 62, the MCU 19 stops recording the video data captured by the imaging unit 11 and stops storing the video data in the storage unit 15. (S7B).

  Thus, by stopping the recording of the wearable camera 10 in cooperation with the recording stop of the in-vehicle recorder 62, for example, the police officer 7 forgets the recording stop operation by the recording switch SW1 of the wearable camera 10 for emergency response. Even in this case, it is possible to stop the recording of the video data at the site 8. Therefore, unnecessary power consumption and memory consumption due to forgetting to stop recording video data can be reduced.

  FIG. 17 illustrates that the in-vehicle recorder 62 stops recording and transmits a recording stop message in S5B and S6B, and the wearable camera 10 receives the recording stop message and stops recording in S7B. Instead, the wearable camera 10 may stop recording and transmit a recording stop message in S5B and S6B, and the in-vehicle recorder 62 may receive the recording stop message and stop recording in S7B.

  Note that the processes of S5B to S7B may be omitted. That is, the recording stop cooperation between the in-vehicle recorder 62 and the wearable camera 10 may not be performed.

  When the recording stop trigger is detected, the in-vehicle recorder 62, for example, if the distance between the in-vehicle recorder 62 and the wearable camera 10 is long and out of the communication range by the wireless LAN, a recording stop message is returned after the wireless connection is restored. You may send it.

  Wearable camera system 100 performs the processing of S8A to S10A after the start of recording in S2B.

  In FIG. 17, there may be a plurality of wearable cameras 10 that start recording upon receiving a recording start message. Similarly, there may be a plurality of wearable cameras 10 that stop recording upon receiving a recording stop message. Similarly, there may be a plurality of wearable cameras 10 that receive attribute information messages and give attribute information. For example, it is assumed that there are a plurality of police officers 7 in the police car 6.

  FIG. 18 is a sequence diagram illustrating a fourth example of the attribute information assigning procedure by the wearable camera system 100. In FIG. 18, it is assumed that the wearable camera 10 starts recording after the in-vehicle recorder 62 and gives attribute information before the in-vehicle recorder 62. In the operation example of FIG. 18, processes similar to those in the operation examples of FIGS. 15 to 17 are denoted by the same step numbers, and description thereof is omitted or simplified.

  The wearable camera system 100 performs the processes of S1, S2B to S7B. Wearable camera system 100 performs the processing of S8-S10 after the start of recording in S4B.

  In FIG. 18, there may be a plurality of wearable cameras 10 that start recording upon receiving a recording start message. Similarly, there may be a plurality of wearable cameras 10 that stop recording upon receiving a recording stop message. Similarly, there may be a plurality of wearable cameras 10 that provide attribute information and notify an attribute information message. For example, it is assumed that there are a plurality of police officers 7 in the police car 6.

  15 to 18 exemplify that the attribute information is given by the wearable camera 10 and the in-vehicle recorder 62, but part or all of the meta information including the attribute information may be given. Moreover, although it has been exemplified that the attribute information message including the attribute information is notified to the communication partner, the meta information message including a part or all of the meta information including the attribute information may be notified. Accordingly, the wearable camera 10 and the in-vehicle recorder 62 can also cooperate in giving meta information. Therefore, for example, the wearable camera 10 or the in-vehicle recorder 62 may add new meta information to the recorded video list held by the own device in response to the attribute information message or the meta information message, or update existing meta information. May be.

  As described above, in the present embodiment, the wearable camera 10 and the in-vehicle recorder 62 start recording in cooperation. Therefore, even when the recording is not started in either the wearable camera 10 or the in-vehicle recorder 62, the wearable camera 10 Recording can be started in response to a recording start message from the other of the in-vehicle recorder 62 and the in-vehicle recorder 62.

  Accordingly, for example, when the police officer 7 is in a hurry for an emergency response and the recording start trigger is generated in the in-vehicle recorder 62 even when the operation input of the recording switch SW1 of the wearable camera 10 is forgotten or cannot be input. In addition, recording with the wearable camera 10 can be started.

  In addition, since the wearable camera 10 and the in-vehicle recorder 62 perform the attribute information in cooperation, even when the attribute information is not provided in either the wearable camera 10 or the in-vehicle recorder 62, the wearable camera 10 and the in-vehicle recorder 62 are provided. Attribute information can be given in response to an attribute information message from either of the recorders 62. When the in-vehicle recorder 62 uses the attribute information provided by the wearable camera 10, it is possible to eliminate the need for inputting attribute information via the in-vehicle PC 63. Further, when the wearable camera 10 uses the attribute information given by the in-vehicle recorder 62, the variation of attribute information that can be given to the wearable camera 10 can be increased, and the attribute information addition function of the wearable camera 10 can be expanded.

  Thus, according to the wearable camera system 100, the convenience at the time of handling the video data imaged with the wearable camera 10 can be improved. Furthermore, the video data captured by the wearable camera 10 or the in-vehicle camera 61 can be easily searched and extracted using the attribute information, and the monitoring performance of the site 8 and the verification performance of the video data can be improved.

  As described above, the wearable camera system 100 according to the present embodiment includes the wearable camera 10 that can be worn by the user, the in-vehicle recorder 62 mounted on the vehicle on which the user rides, and the on-vehicle camera 61 mounted on the vehicle.

The wearable camera 10 includes a second imaging unit that captures video, a second communication unit that communicates with the in-vehicle recorder 62 as a communication partner, and second video data captured by the second imaging unit. A second recording unit for recording the second video information, and a second information adding unit for adding second attribute information related to the second video data to the second video data.

  The wearable camera 10 starts the recording by the second recording unit, then gives the second attribute information to the second video data, transmits the second attribute information to the in-vehicle recorder 62, and the in-vehicle recorder 62 62 receives the second attribute information and assigns the second attribute information as the first attribute information to the first video data. Alternatively, the in-vehicle recorder 62 gives the first attribute information to the first video data after starting the recording by the first recording unit, and transmits the first attribute information to the wearable camera 10. The wearable camera 10 receives the first attribute information and assigns the first attribute information to the second video data as the second attribute information.

The second information providing unit is, for example, the MCU 19. The user is a police officer 7, for example. The vehicle is a police car 6, for example.

  Thereby, since wearable camera 10 and in-vehicle recorder 62 give attribute information in cooperation, either one of wearable camera 10 and in-vehicle recorder 62 assists the other attribute information giving operation, and both devices Giving the attribute information can be simplified. For example, by using the attribute information provided by the wearable camera 10 as the attribute information provided by the in-vehicle recorder 62, the user can omit an operation input to the input device (for example, the in-vehicle PC 63). Further, for example, by using the attribute information provided by the in-vehicle recorder 62 as the attribute information provided by the wearable camera 10, various types of attribute information can be provided by the wearable camera 10. Therefore, the wearable camera system 100 can improve convenience when handling video data captured by the wearable camera 10 or the in-vehicle camera 61.

  Further, the wearable camera system 100 includes recording start information including that the recording is started when either the in-vehicle recorder 62 or the wearable camera 10 starts recording by either the in-vehicle recorder 62 or the wearable camera 10. Alternatively, it may be transmitted to either the in-vehicle recorder 62 or the wearable camera 10. Either the in-vehicle recorder 62 or the wearable camera 10 may start recording after receiving the recording start information.

  As a result, the wearable camera 10 and the in-vehicle recorder 62 start recording in cooperation with each other, so that either the wearable camera 10 or the in-vehicle recorder 62 assists in the operation of the other, and recording of video data in both devices is performed. Certainty can be improved. Therefore, the wearable camera system 100 can improve convenience when handling video data captured by the wearable camera 10, and can reduce omissions in recording video data. Therefore, for example, the monitoring performance by the wearable camera system 100 and the evidence performance of video data can be improved.

  In the wearable camera system 100, the in-vehicle recorder 62 may acquire the first attribute information from an input device that inputs the first attribute information. The wearable camera 10 may include an operation unit that receives a second attribute information providing operation. The input device is, for example, the in-vehicle PC 63. The operation unit is, for example, an attribute information addition switch SW3.
