Description

Technical Field

[0001] The present invention relates to a vehicle recording device, a vehicle recording control method and a program. Background Art

[0002] Since most of the dashcams installed in vehicles and taking pictures of the surroundings of the vehicle are installed near the front glass or rear glass of the vehicle, some dashcams do not have a display screen from the perspective of ensuring the field of vision of the vehicle passengers. In addition, among such dashcams without a display screen, some dashcams allow the user to communicate with the dashcam through a pre-registered portable terminal so that the user can refer to the information obtained by the dashcam in the portable terminal. For example, in Patent Document 1, when an event such as a collision is detected by a vehicle device, information related to the event can be sent to the portable terminal through wireless communication, and the information related to the event can be confirmed in the portable terminal.

[0042] Hereinafter, the vehicle recording device, vehicle recording control method and program of the present embodiment are described in detail based on the accompanying drawings. In addition, the present invention is not limited to the embodiment. In addition, the structural elements in the following embodiments include elements that can be replaced and easily thought of by those skilled in the art, or substantially the same elements.

[0043] [First embodiment]

[0044] <Vehicle Recording Device>

[0045] Figure 1 1 is a block diagram showing a configuration example of a vehicle recording device 10 according to a first embodiment. The vehicle recording device 10 is a so-called driving recorder, which is installed near the front glass or the rear window glass in the vehicle interior and is usually driven by the power supplied by the vehicle. In addition, the vehicle recording device 10 has a built-in battery (not shown), and can be driven by the built-in battery even when the power supply to the vehicle is interrupted due to a vehicle accident or the like. In addition to being mounted on the vehicle, the vehicle recording device 10 can also be a portable device that can be used on the vehicle.

[0046] The vehicle recording device 10 includes an imaging unit 210 , a recording unit 220 , an operation unit 230 , a sensor 240 , a communication unit 250 , a GNSS (Global Navigation Satellite System) receiving unit 260 , and a vehicle recording control device (hereinafter referred to as “control device”) 100 .

[0047] The photographing unit 210 is a camera that can photograph the surroundings of the vehicle on which the vehicle recording device 10 is mounted and output as an electrical signal. In the first embodiment, the photographing unit 210 is disposed near the front glass in the vehicle compartment facing forward and photographs the surroundings centered on the front of the vehicle. The photographing unit 210 photographs a wide angle, for example, a photographing range of about 180° in the horizontal direction. The photographing unit 210 generates the photographed photographing data 300 (see Figure 2 ) is output to the shooting data acquisition unit 120 of the control device 100.

[0048] The recording unit 220 is used for temporary storage and preservation of data in the vehicle recording device 10. The recording unit 220 is, for example, a semiconductor memory element such as a RAM (Random Access Memory), a flash memory (Flash Memory), or a recording unit such as a memory card. Alternatively, it may be an external recording unit wirelessly connected via a communication device not shown. The recording unit 220 records the captured data 300 acquired by the captured data acquisition unit 120 based on a control signal output from the recording control unit 123 of the control device 100.

[0049] The operation unit 230 is an input unit that can receive various operations on the vehicle recording device 10. For example, the operation unit 230 can receive a time setting of one video data when recording the shooting data 300 as video data in the recording unit 220, that is, a setting of how many time intervals the video data is generated. In addition, the operation unit 230 can receive an operation of manually recording an event. The operation unit 230 outputs the input operation information to the operation control unit 124 of the control device 100.

[0050] The sensor 240 is an event detection unit that can detect an event on the vehicle equipped with the vehicle recording device 10, and outputs the detection result to the event detection unit 125 of the control device 100. The sensor 240 is a so-called acceleration sensor that detects acceleration, for example, detects acceleration in three-axis directions. The three-axis directions refer to the front-back direction, the left-right direction, and the up-down direction of the vehicle. The sensor 240 can detect an impact on the vehicle through the acceleration in the three-axis directions.

[0051] The communication unit 250 is a communication means capable of communicating with an external communication terminal 400. The communication unit 250 can wirelessly communicate with the external communication terminal 400 of the vehicle recording device 10 by means of Wi-Fi (registered trademark), Bluetooth (registered trademark), etc. The communication terminal 400 in this case includes, for example, a portable information terminal device such as a smartphone, a tablet computer, and a notebook personal computer.

[0052] The GNSS receiving unit 260 receives radio waves transmitted from a plurality of positioning satellites included in the GNSS, and outputs the received radio wave signals to the position information acquiring unit 128 of the control device 100 .

[0053] The control device 100 is, for example, a calculation processing device (control device) composed of a CPU (Central Processing Unit) and the like. The control device 100 loads the stored program into the memory and executes the commands contained in the program. The control device 100 includes an internal memory not shown in the figure, and the internal memory is used for temporary storage of data in the control device 100, etc. The control device 100 has a shooting data acquisition unit 120 connected to the bus 110, a buffer memory 121, a shooting data processing unit 122, a recording control unit 123, an operation control unit 124, an event detection unit 125, a communication control unit 126, an access control unit 127, and a position information acquisition unit 128.

[0054] The imaging data acquisition unit 120 acquires the imaging data 300 of the surrounding area of ​​the vehicle. More specifically, the imaging data acquisition unit 120 acquires the imaging data 300 output from the imaging unit 210 of the surrounding area of ​​the vehicle.

[0055] The buffer memory 121 is a memory for temporarily storing the imaging data. For example, the buffer memory 121 is a memory for temporarily recording the imaging data 300 for a certain period of time acquired by the imaging data acquisition unit 120 while updating.

[0056] The shooting data processing unit 122 converts the shooting data 300 (hereinafter referred to as "temporary shooting data") temporarily stored in the buffer memory 121 into any file format such as MP4 format after being encoded by a codec of any method such as H.264 or MPEG-4 (Moving Picture Experts Group). The shooting data processing unit 122 generates the shooting data 300 having video data of a certain time as one file based on the temporary shooting data. In detail, the shooting data processing unit 122 generates the shooting data 300 of a predetermined time as one file from the temporary shooting data in the order of recording, and generates a plurality of files consisting of the shooting data 300 of the predetermined time according to the shooting time in the shooting unit 210. In this case, the predetermined time uses the time (for example, 60 seconds) set by the input operation of the operation unit 230. The shooting data processing unit 122 outputs the shooting data 300 generated in this way to the recording control unit 123. In addition, the time of the shooting data 300 generated as one file is set to 60 seconds as an example, but it is not limited to this. In addition, the image data 300 mentioned here may be data including sound in addition to the imaged image.

[0057] Figure 2 2 is a conceptual diagram of loop recording of the photographic data 300. The recording control unit 123 controls the recording of the photographic data 300 that has been filed by the photographic data processing unit 122 in the recording unit 220. The recording control unit 123 performs loop recording processing when loop recording is set, and records the photographic data 300 that has been filed by the photographic data processing unit 122 in the recording unit 220 as overwritable photographic data 300. More specifically, during the execution of the loop recording processing, the recording control unit 123 continuously records the photographic data 300 generated by the photographic data processing unit 122 in the recording unit 220, and when the capacity of the recording unit 220 is full, the new photographic data 300 is overwritten and recorded on the oldest photographic data 300.

[0058] The operation control unit 124 acquires operation information of the operation received by the operation unit 230. For example, the operation control unit 124 acquires setting information of time interval when saving the image data 300 as a video data file at predetermined time intervals, operation information of whether to perform manual event recording, etc., and outputs these control signals.

[0059] The event detection unit 125 detects an event against the vehicle. The method by which the event detection unit 125 detects an event against the vehicle is arbitrary, but as an example, the event detection unit 125 detects an event based on the detection result of the sensor 240. In this case, when an acceleration greater than an acceleration threshold detected by the sensor 240 is detected, the event detection unit 125 detects it as an event. The acceleration detected as an event by the event detection unit 125 is set in advance to a threshold value such that an impact against the vehicle is detected.

[0060] Figure 3 This is a conceptual diagram of storing the captured data 300 as normal recorded data 310 or event recorded data 320. When the event detection unit 125 detects an event, the recording control unit 123 stores the captured data 300 for a predetermined period including at least the time point when the event was detected in the captured data 300 generated by the captured data processing unit 122 as event recorded data 320 that is prohibited from being overwritten in the recording unit 220.

[0061] In other words, the recording control unit 123 stores the captured data 300 acquired by the captured data acquisition unit 120 as normal recorded data 310 not based on an event and event recorded data 320 based on an event in the recording unit 220. That is, the recording control unit 123 stores the captured data 300 not based on an event among the captured data 300 acquired by the captured data acquisition unit 120 as normal recorded data 310 that can be overwritten, and stores the captured data 300 based on an event as event recorded data 320 that cannot be overwritten.

[0062] The prescribed period caused by the detection of an event, which is a criterion for determining whether the photographic data 300 is photographic data 300 not based on an event or photographic data 300 based on an event, is, for example, a prescribed period from the time when the event is detected, or a period before and after the time when the event is detected including the time when the event is detected. In the case where the photographic data 300 is data photographed in the prescribed period from the time when the event is detected, or in the period before and after the time when the event is detected including the time when the event is detected, the recording control unit 123 stores it as event-based event recording data 320, and in the case of data photographed outside these periods, it is stored as normal recording data 310 not based on an event.

[0063] Whether it is non-event-based captured data 300 or event-based captured data 300 may be determined based on the recording area recorded in the recording unit 220. For example, event-based captured data 300 is stored in a prohibited overwrite area different from non-event-based captured data 300.

[0064] The communication control unit 126 establishes a connection with the external communication terminal 400 communicating with the communication unit 250, and controls the communication with the communication terminal 400 via the communication unit 250. That is, the communication control unit 126 establishes a connection with the communication terminal 400 by becoming a state in which communication with the external communication terminal 400 can be performed via the communication unit 250, and performs communication control when sending and receiving signals and data with the communication terminal 400.

[0065] The establishment of the connection with the communication terminal 400 may be, for example, provided that the communication unit 250 can communicate with the communication terminal 400 based on NFC (Near Field Communication), and by performing NFC authentication of the communication terminal 400, a state is established in which the authenticated communication terminal 400 and the communication unit 250 can communicate via Wi-Fi. In addition, for example, the communication unit 250 is configured to be able to communicate using Bluetooth, and by pairing with the communication terminal 400 via Bluetooth connection, it is possible to easily establish a connection with the same communication terminal 400 next time and thereafter.

[0066] The access control unit 127 controls whether the communication terminal 400 can access the photographic data 300 stored in the recording unit 220, depending on whether the communication terminal 400 connected by the communication control unit 126 is a pre-registered communication terminal 400. That is, the vehicle recording device 10 can register the communication terminal 400, and the access control unit 127 makes the access method to the photographic data 300 stored in the recording unit 220 different depending on whether the communication terminal 400 is registered.

[0067] Specifically, when the communication terminal 400 to which the communication control unit 126 has established a connection is a registered terminal 410, which is a communication terminal 400 that has been registered in advance, the access control unit 127 controls the registered terminal 410 to be able to access the normal log data 310 and the event log data 320. On the other hand, when the communication terminal 400 to which the communication control unit 126 has established a connection is an unregistered terminal 420, which is a communication terminal 400 that has not been registered in advance, the access control unit 127 controls the unregistered terminal 420 to be unable to access the normal log data 310 but to be able to access the event log data 320.

[0068] The registration of the communication terminal 400 is performed by performing an input operation related to the registration of the communication terminal 400 on the operation unit 230. For example, in a state where the connection of the communication terminal 400 is established by the communication control unit 126, by performing an input operation related to the registration on the operation unit 230, the communication terminal 400 that has established the current connection is registered as the registered terminal 410. Alternatively, in a state where the mode for registering the communication terminal 400 is entered by performing an input operation related to the registration on the operation unit 230, the connection of the communication terminal 400 is established, thereby registering the communication terminal 400 that has established the connection as the registered terminal 410.

[0069] As described above, information related to the communication terminal 400 registered as the registered terminal 410 is stored in the internal memory of the control device 100. As the information related to the communication terminal 400, for example, independent information attached to the communication terminal 400, such as a number that can identify the communication terminal 400, is registered. The access control unit 127 compares the information related to the communication terminal 400 to which the communication control unit 126 has established a connection with the information of the registered terminal 410 stored in the internal memory, and determines whether the communication terminal 400 to which the connection has been established is the registered terminal 410.

[0070] The position information acquisition unit 128 calculates the current position information of the vehicle by a known method based on the radio waves received by the GNSS reception unit 260. When the event detection unit 125 detects an event, the position information calculated by the position information acquisition unit 128 is stored together with the event log data 320.

[0071] <Processing in Vehicle Recording Device>

[0072] Next, use Figure 4 , the processing flow in the control device 100 is explained. Figure 4 This is a flowchart showing the flow of processing in the vehicle recording control device 100 according to the first embodiment. Here, a case where loop recording processing is performed will be described.

[0073] When the vehicle recording device 10 starts to be used, the control device 100 starts normal recording (step S101). That is, the shooting data acquisition unit 120 acquires the shooting data 300 captured by the shooting unit 210 that captures the surroundings of the vehicle, and stores it in the recording unit 220 as normal recording data 310. In detail, the control device 100 generates files at predetermined time intervals by the shooting data processing unit 122 based on the shooting data 300 acquired by the shooting data acquisition unit 120 and recorded in the buffer memory 121, and the recording control unit 123 cyclically records the files in the recording unit 220 as normal recording data 310.

[0074] Next, the control device 100 determines whether an event for the vehicle is detected by the event detection unit 125 (step S102). Specifically, the event detection unit 125 detects the occurrence of an event based on whether the acceleration detected by the sensor 240 is greater than a preset threshold. That is, the event detection unit 125 does not detect an event for the vehicle when the acceleration detected by the sensor 240 is less than the threshold. On the other hand, when the acceleration detected by the sensor 240 is greater than the threshold, the event detection unit 125 detects that a large impact has occurred on the vehicle and an event has occurred on the vehicle.

[0075] In this way, when the event detection unit 125 that detects an event based on the acceleration detected by the sensor 240 detects that an event has occurred on the vehicle (step S102: "Yes" judgment), the control device 100 saves the event record data 320 (step S103). In detail, when the event detection unit 125 detects that an event has occurred on the vehicle, the control device 100 saves the shooting data 300 of a predetermined period including at least the time point of the event occurrence as the event record data 320 prohibited from being overwritten in the recording unit 220 through the recording control unit 123.

[0076] After the event recording data 320 is saved, the control device 100 determines whether to end the recording process of the image data 300 by the vehicle recording device 10 (step S104). In addition, when the event detection unit 125 does not detect an event for the vehicle (step S102: "No" determination), the control device 100 also determines whether to end the recording process of the image data 300 (step S104).

[0077] Specifically, the control device 100 determines whether to terminate the recording process of the photographing data 300 by the vehicle recording device 10 based on whether the operation control unit 124 outputs information related to the operation of the operation received from the acquisition operation unit 230. Alternatively, the vehicle ends and the power supply from the vehicle stops, thereby terminating the recording process of the photographing data 300 by the vehicle recording device 10. If the operation control unit 124 does not output information related to the operation of the end (step S104: "No" determination), the control device 100 returns to step S102 and continues the recording process of the photographing data 300 by the vehicle recording device 10. That is, the loop recording process of the photographing data 300 by the control device 100 continues.

[0078] On the other hand, when it is determined that the recording process of the image data 300 is to be terminated (step S104 : “Yes” determination), the recording process of the image data 300 by the vehicle recording device 10 is terminated.

[0079] In addition, the vehicle recording device 10 is normally driven by the power supplied from the vehicle, so when the power supply to the vehicle recording device 10 is stopped due to the end of the vehicle operation, the vehicle recording device 10 substantially ends the recording process of the image data 300. On the other hand, when the power supply from the vehicle is interrupted due to a vehicle accident, the vehicle recording device 10 continues to be driven by the built-in battery and continues the recording process of the image data 300.

[0080] As described above, the vehicle recording device 10 that stores the captured data 300 captured by the capturing unit 210 in the recording unit 220 can communicate with the communication terminal 400, and the communication terminal 400 that has established a connection through the communication control unit 126 can access the stored captured data 300. Therefore, the captured data 300 stored in the recording unit 220 of the vehicle recording device 10 can be confirmed through the communication terminal 400 that has established a connection. For example, when the captured data 300 stored in the recording unit 220 is video data, the captured data 300 can be viewed as an animation through the communication terminal 400 that has established a connection.

[0081] Here, the imaged data 300 is stored as normal recorded data 310 or event recorded data 320 , but the method of accessing the imaged data 300 by the connected communication terminal 400 differs depending on whether the communication terminal 400 is pre-registered in the vehicle recording device 10 .

[0082] That is, if the communication terminal 400 connected is the registered terminal 410 registered in advance, the registered terminal 410 can access the normal log data 310 and the event log data 320. Thus, the registered terminal 410 can check the normal log data 310 and the event log data 320 stored in the recording unit 220.

[0083] On the other hand, when the communication terminal 400 with which the connection has been established is an unregistered terminal 420 that has not been registered in advance, the unregistered terminal 420 cannot access the normal log data 310 but can access the event log data 320. Thus, although the unregistered terminal 420 cannot confirm the normal log data 310 stored in the recording unit 220, it can confirm the event log data 320.

[0084] Next, use Figure 5 , the access processing flow of the communication terminal 400 communicating with the vehicle recording device 10 to the photographic data 300 will be described. Figure 51 is a flowchart showing a process flow related to access to the captured data 300 in the communication terminal 400. During use of the vehicle recording device 10, the control device 100 continues to receive a connection request from the communication terminal 400, and establishes a connection when there is a connection request from the communication terminal 400. Therefore, during use of the vehicle recording device 10, the control device 100 continuously calls a subroutine or program related to connection with the communication terminal 400, and performs processing related to connection with the communication terminal 400.

[0085] In the process related to the connection with the communication terminal 400, first, it is determined whether there is a connection request from the communication terminal 400 (step S201). Specifically, the control device 100 determines whether there is a connection request from the communication terminal 400 with respect to the communication control unit 126 that controls the communication with the communication terminal 400 via the communication unit 250. That is, the communication unit 250 determines whether a signal of the connection request from the communication terminal 400 is received.

[0086] Through this determination, when the communication control unit 126 or the communication unit 250 determines that there is no connection request from the communication terminal 400 (step S201: "No" determination), the processing related to the connection with the communication terminal 400 is terminated, and when the processing is called again, it starts again from step S201.

[0087] On the other hand, when communication control unit 126 or communication unit 250 determines that there is a connection request from communication terminal 400 (step S201 : Yes determination), communication control unit 126 establishes a connection with communication terminal 400 via communication unit 250 .

[0088] After the connection with the communication terminal 400 is established by the communication control unit 126, the control device 100 then determines whether the communication terminal 400 with which the connection has been established is a pre-registered communication terminal 400 (step S202). Specifically, the control device 100 determines whether the communication terminal 400 with which the connection has been established by the communication control unit 126 is a pre-registered registered terminal 410 or an unregistered terminal 420 that has not been pre-registered.

[0089] By this determination, when the communication terminal 400 with which the connection has been established is determined to be the registered terminal 410 as the communication terminal 400 registered in advance (step S202: "Yes" determination), access to the normal log data 310 and the event log data 320 is permitted (step S203). That is, when the communication terminal 400 with which the connection has been established is the registered terminal 410 as the communication terminal 400 registered in advance, the access control unit 127 permits the registered terminal 410 to access the captured data 300 stored in the recording unit 220 for all captured data 300. Thus, the normal log data 310 and the event log data 320 can be accessed by the registered terminal 410 with which the connection has been established, and thus the normal log data 310 and the event log data 320 can be confirmed by the registered terminal 410.

[0090] When the communication terminal 400 with which the connection has been established is the registration terminal 410, for example, a list of normal recorded data 310 and event recorded data 320, a setting menu of the vehicle recording device 10, etc. are displayed on the registration terminal 410 side. The registration terminal 410 can select and reproduce any captured data 300 from the list of normal recorded data 310 and event recorded data 320, or acquire (download) the captured data 300. Thus, the registration terminal 410 can check the normal recorded data 310 and the event recorded data 320.

[0091] On the other hand, when it is determined that the communication terminal 400 with which the connection has been established is not the registered terminal 410 that has been registered in advance (step S202: "No" determination), access to the event log data 320 is permitted (step S204). That is, when the communication terminal 400 with which the connection has been established is an unregistered terminal 420 that is a communication terminal 400 that has not been registered in advance, the access control unit 127 allows the unregistered terminal 420 to access the captured data 300 stored in the recording unit 220, which is not permitted for the normal log data 310 but permitted for the event log data 320. As a result, the unregistered terminal 420 with which the connection has been established cannot access the normal log data 310 but can access the event log data 320, so that only confirmation of the event log data 320 can be performed by the unregistered terminal 420.

[0092] When the communication terminal 400 with which the connection is established is the unregistered terminal 420, for example, only a list of the event log data 320 is displayed on the unregistered terminal 420 side, and the selected event log data 320 can be reproduced, so that only the event log data 320 can be confirmed. In addition, when the communication terminal 400 with which the connection is established is the unregistered terminal 420, it is preferably set so that the captured data 300 cannot be downloaded to the unregistered terminal 420.

[0093] As described above, if access to the photographic data 300 is restricted by the connected communication terminal 400, it is then determined whether the connection of the communication terminal 400 is terminated (step S205). Specifically, the control device 100 determines whether the connection between the communication terminal 400 and the communication control unit 126 via the communication unit 250 is continued.

[0094] Through this judgment, when it is determined that the establishment of the connection between the communication terminal 400 and the communication control unit 126 is still continuing and the connection of the communication terminal 400 has not been terminated (step S205: "No" judgment), the state of allowing access in step S203 or step S204 is maintained, and the judgment of whether the connection of the communication terminal 400 is terminated is repeated.

[0095] In contrast, when it is determined that the connection between the communication terminal 400 and the communication control unit 126 is terminated and the connection of the communication terminal 400 has been terminated (step S205: "Yes" judgment), the processing related to the connection of the communication terminal 400 is terminated, and when the processing is called again, it starts again from step S201.

[0096] <Effect>

[0097] As described above, in the first embodiment, when the communication terminal 400 connected to the vehicle recording device 10 is the registered terminal 410, the registered terminal 410 can access the normal recorded data 310 and the event recorded data 320. Therefore, by registering the communication terminal 400 connected to the vehicle recording device 10, for example, the communication terminal 400 used by the driver such as the smartphone held by the user, as the registered terminal 410, the photographed data 300 can be easily confirmed through the registered terminal 410.

[0098] Furthermore, when the communication terminal 400 that has established a connection with the vehicle recording device 10 is an unregistered terminal 420, the unregistered terminal 420 cannot access the normal recorded data 310. Therefore, when the communication terminal 400 that has established a connection with the vehicle recording device 10 is a communication terminal 400 that is not registered in the vehicle recording device 10, since the normal recorded data 310 cannot be confirmed, it is possible to prevent a third party from being able to confirm the normal recorded data 310 through the unregistered terminal 420. Thus, the normal recorded data 310 can be confirmed, and information on the vehicle's visited places can be prevented from being accidentally known to a third party, and the user's privacy can be protected.

[0099] On the other hand, even if the communication terminal 400 that has established a connection with the vehicle recording device 10 is a communication terminal 400 that is not registered in the vehicle recording device 10, the unregistered terminal 420 can access the event record data 320. Therefore, a third party can easily confirm the event record data 320 recorded when an event such as a vehicle accident occurs through the unregistered terminal 420. Thus, even if the event record data 320 cannot be confirmed using the registered terminal 410 held by the vehicle driver due to an event such as an accident, the event record data 320 can be confirmed through the unregistered terminal 420 held by the third party, and the status of the event can be easily confirmed through the unregistered terminal 420. As a result, information related to the event can be confirmed while ensuring protection of privacy.

[0100] [Second embodiment]

[0101] The vehicle recording device 10 according to the second embodiment has a substantially similar structure to the vehicle recording device 10 according to the first embodiment, but is characterized in that access to the latest event record data 320a is permitted to an unregistered terminal 420. The other structures are the same as those of the first embodiment, and thus the description thereof is omitted, and the same reference numerals are used.

[0102] Figure 6 3 is a conceptual diagram of a case where a plurality of event record data 320 are stored. After the vehicle recording device 10 detects an event and stores the image data 300 as the event record data 320, an event may be detected due to an accident occurring in the vehicle on which the vehicle recording device 10 is mounted, and the image data 300 may be stored again as the event record data 320. In addition, since the event record data 320 is stored in the recording unit 220 with overwriting prohibited, even when the normal record data 310 is overwritten by loop recording, the event record data 320 is continuously stored in the recording unit 220. Therefore, when the vehicle recording device 10 detects an event multiple times, a plurality of event record data 320 are stored in the recording unit 220.

[0103] In the vehicle recording device 10 according to the second embodiment, when receiving a connection request from the unregistered terminal 420, the access control unit 127 of the control device 100 permits the unregistered terminal 420 to access the latest event record data 320a. Therefore, when the event record data 320 is stored in the recording unit 220, the unregistered terminal 420 that has established a connection cannot access the old event record data 320 and can only access the latest event record data 320a.

[0104] For example, when the connection between the vehicle recording device 10 and the unregistered terminal 420 is established, the presence or absence of the latest event record data 320a is displayed on the unregistered terminal 420 side, and the latest event record data 320a can be reproduced in the unregistered terminal 420. Thus, only the latest event record data 320a can be confirmed in the unregistered terminal 420 that has established a connection with the vehicle recording device 10. In addition, in the unregistered terminal 420, it is preferably set to allow only the reproduction of the latest event record data 320a and not to download the latest event record data 320a.

[0105] Figure 7 1 is a flowchart showing a process flow related to access to the captured data 300 at the communication terminal 400 in the vehicle recording device 10 according to the second embodiment. In the vehicle recording device 10 according to the second embodiment, in the process related to the connection with the communication terminal 400, first, it is determined whether there is a connection request from the communication terminal 400 (step S201). Through this determination, if it is determined that there is no connection request from the communication terminal 400 (step S201: "No" determination), the process related to the connection with the communication terminal 400 is terminated, and when the process is called again, it starts again from step S201.

[0106] On the other hand, when it is determined that there is a connection request from communication terminal 400 (step S201: "Yes" determination), a connection is established with communication terminal 400 via communication unit 250, and it is determined whether the connected communication terminal 400 is a pre-registered communication terminal 400 (step S202).

[0107] By this determination, when the connected communication terminal 400 is determined to be the registered terminal 410 as the communication terminal 400 registered in advance (step S202: "Yes" determination), access to the normal log data 310 and the event log data 320 is permitted (step S203).

[0108] On the other hand, when it is determined that the communication terminal 400 with which the connection has been established is not the registered terminal 410 that has been registered in advance (step S202: "No" determination), access to the most recent event log data 320a is permitted (step S211). That is, when the communication terminal 400 with which the connection has been established is the unregistered terminal 420 that is a communication terminal 400 that has not been registered in advance, the access control unit 127 sets the access of the unregistered terminal 420 to the captured data 300 stored in the recording unit 220 to be not permitted to the normal log data 310 and the event log data 320 that is not the most recent event log data, but permitted to the most recent event log data 320a.

[0109] In the case where a plurality of event log data 320 are stored, in addition to events caused by accidents, there is a case where the event detection unit 125 detects events for acceleration caused by emergency braking or the like even in a state where there is no accident. In addition, in the case where a third party needs to confirm the event log data 320 using the unregistered terminal 420, it is a case where the event log data based on the accident is confirmed immediately after the accident occurs. Therefore, for example, in the case where a plurality of event log data 320 are stored in the recording unit 220, the access control unit 127 does not allow the unregistered terminal 420 to access event log data 320 other than the most recent event log data 320a, and only allows access to the most recent event log data 320a. As a result, through the unregistered terminal 420 that has established a connection, except for the normal log data 310, event log data 320 other than the most recent event log data 320a cannot be accessed, but the most recent event log data 320a can be accessed. Therefore, when the connection between the vehicle recording device 10 and the unregistered terminal 420 is established, only the latest event record data 320 a can be checked through the unregistered terminal 420 with which the connection has been established.

[0110] As described above, if access to the photographed data 300 is restricted based on the communication terminal 400 that has established a connection, it is determined whether the connection of the communication terminal 400 has ended (step S205). Through this determination, if it is determined that the connection of the communication terminal 400 has not ended (step S205: "No" determination), the state of allowing access in step S203 or step S211 is maintained, and the determination of whether the connection of the communication terminal 400 has ended is repeated. On the other hand, if it is determined that the connection of the communication terminal 400 has ended (step S205: "Yes" determination), the processing related to the connection of the communication terminal 400 is ended, and when the processing is called again, it starts again from step S201.

[0111] <Effect>

[0112] As described above, in the second embodiment, when the access control unit 127 receives a connection request from the unregistered terminal 420, it does not allow the unregistered terminal 420 to access event log data 320 other than the most recent event log data 320a, except for the normal log data 310, but allows access to the most recent event log data 320a. Thus, even when a plurality of event log data 320 are stored in the recording unit 220, it is possible to prevent a third party from confirming event log data 320 other than the most recent event log data 320a through the unregistered terminal 420. Therefore, it is possible to prevent an event that occurred in the vehicle in the past from being accidentally known to a third party, and the user's privacy can be more reliably protected.

[0113] On the other hand, since the latest event record data 320a can be accessed by using the unregistered terminal 420, a third party can easily check the latest event record data 320a recorded when an event such as a vehicle accident occurs through the unregistered terminal 420. As a result, the cause of the latest accident or other event can be easily confirmed through the unregistered terminal 420. As a result, information related to the event can be confirmed while ensuring privacy protection.

[0114] [Third Embodiment]

[0115] The vehicle recording device 10 according to the third embodiment has a substantially similar structure to the vehicle recording device 10 according to the second embodiment, and is characterized in that after an event is detected, access to the most recent event record data 320a is permitted to the unregistered terminal 420 only within a predetermined period. The other structures are the same as those of the second embodiment, and thus their description is omitted and the same reference numerals are used.

[0116] In the vehicle recording device 10 according to the third embodiment, the access control unit 127 of the control device 100 allows the unregistered terminal 420 to access the latest event record data 320a when a connection request is received from the unregistered terminal 420 within a predetermined period after the event detection unit 125 detects the event. In addition, when the access control unit 127 receives a connection request from the unregistered terminal 420 after the predetermined period has passed since the event detection unit 125 detected the event, it does not allow the unregistered terminal 420 to access the latest event record data 320a. The predetermined period in this case is set in advance and stored in, for example, the internal memory of the control device 100.

[0117] That is, in the third embodiment, unlike the second embodiment, a restriction is set on the period during which the unregistered terminal 420 can access the most recent event log data 320a. Therefore, in the third embodiment, the unregistered terminal 420 can access the most recent event log data 320a only within a prescribed period after the event is detected by the event detection unit 125. In other words, if the prescribed period has passed after the event is detected by the event detection unit 125, the unregistered terminal 420 cannot access any of the captured data 300 stored in the recording unit 220 including the most recent event log data 320a.

[0118] For example, when the vehicle recording device 10 and the unregistered terminal 420 are connected, if the connection between the vehicle recording device 10 and the unregistered terminal 420 is within a predetermined period from when the event detection unit 125 detects an event, the presence or absence of the latest event record data 320a is displayed, and the latest event record data 320a can be reproduced in the unregistered terminal 420. On the other hand, if the connection between the vehicle recording device 10 and the unregistered terminal 420 exceeds the predetermined period from when the event detection unit 125 detects an event, the unregistered terminal 420 is not allowed to access the captured data 300 including the latest event record data 320a.

[0119] That is, when the specified period is set to 5 minutes, for example, the access control unit 127 allows the unregistered terminal 420 to access the most recent event record data 320a within 5 minutes from the time the event detection unit 125 detects the event, and does not allow the unregistered terminal 420 to access the captured data 300 if it exceeds 5 minutes.

[0120] Even within a predetermined period after the event detection unit 125 detects an event, the unregistered terminal 420 is allowed to reproduce only the latest event log data 320a, and preferably is set so that the latest event log data 320a cannot be downloaded.

[0121] Figure 8 The flowchart is a flowchart showing the processing flow related to the access to the photographed data 300 in the communication terminal 400 in the vehicle recording device 10 according to the third embodiment. In the vehicle recording device 10 according to the third embodiment, when it is determined that the communication terminal 400 with which the connection has been established is not the registered terminal 410 that has been pre-registered (step S202: "No" determination), it is determined whether it is within a prescribed period from the detection of the event (step S221). In detail, when the communication terminal 400 with which the connection has been established is an unregistered terminal 420 that is a communication terminal 400 that has not been pre-registered, the control device 100 first determines whether it is within a prescribed period set in advance from the detection of the event by the event detection unit 125.

[0122] Through this determination, if it is determined that it is within the prescribed period from the detection of the event (step S221: "Yes" determination), access to the most recent event log data 320a is permitted (step S222). That is, if it is determined that it is within the prescribed period set in advance from the detection of the event by the event detection unit 125, the access control unit 127 permits the unregistered terminal 420 to access the captured data 300 stored in the recording unit 220 only for the most recent event log data 320a.

[0123] On the other hand, if it is determined that it is not within the prescribed period from the detection of the event (step S221: "No" determination), access by the unregistered terminal 420 is not permitted (step S223). That is, the access control unit 127 does not permit the unregistered terminal 420 to access the captured data 300 stored in the recording unit 220 for any captured data 300 including the most recent event record data 320a.

[0124] As described above, if access to the captured data 300 is restricted based on the communication terminal 400 to which a connection has been established, the state of allowing access in step S203 or step S222 or the state of not allowing access in step S223 is maintained until it is determined that the connection of the communication terminal 400 has been terminated (step S205: "Yes" judgment), and the determination of whether the connection of the communication terminal 400 has been terminated is repeatedly performed (step S205).

[0125] <Effect>

[0126] As described above, in the third embodiment, after the event detection unit 125 detects an event, the access control unit 127 allows the unregistered terminal 420 to access the latest event log data 320a when a connection request is received from the unregistered terminal 420 within a prescribed period, and does not allow access to the latest event log data 320a when the prescribed period has expired. Thus, even when a long time has passed since the occurrence of an event such as a vehicle accident, it is possible to prevent a third party from being able to confirm the latest event log data 320a through the unregistered terminal 420. Therefore, it is possible to prevent an event that has passed since the occurrence of the event from being accidentally known to a third party, and it is possible to more reliably protect the privacy of the user.

[0127] In addition, after the event detection unit 125 detects an event, if a third party confirms the latest event log data 320a through the unregistered terminal 420 within a specified period, it is possible to prevent other third parties from confirming the latest event log data 320a through the unregistered terminal 420. That is, if the specified period has passed after the event is detected, the unregistered terminal 420 is not allowed to access the latest event log data 320a, so that it is possible to prevent multiple third parties from accessing the latest event log data 320a at different times through the unregistered terminal 420 and confirming the latest event log data 320a. In this way, the number of third parties who can confirm the latest event log data 320a using the unregistered terminal 420 can be limited, and the event such as a vehicle accident can be prevented from being known by multiple third parties, so that the privacy of the user can be more reliably protected.

[0128] On the other hand, after the event is detected, the latest event log data 320a can be accessed through the unregistered terminal 420 within a prescribed period, so that within the prescribed period, a third party can easily confirm the latest event log data 320a recorded when the event occurred through the unregistered terminal 420. Therefore, after an event such as a vehicle accident occurs, within the prescribed period, the cause of the event can be easily confirmed through the unregistered terminal 420. As a result, information related to the event can be confirmed while ensuring privacy protection.

[0129] [Fourth Embodiment]

[0130] The vehicle recording device 10 according to the fourth embodiment has substantially the same structure as the vehicle recording device 10 according to the first embodiment, but is characterized in that the communication terminal 400 is allowed to access the photographic data 300 stored in the recording unit 220 when the vehicle is stopped. The other structures are the same as those of the first embodiment, and therefore the description thereof is omitted and the same reference numerals are given.

[0131] Fig. 9 1 is a block diagram showing a configuration example of a vehicle recording device 10 according to a fourth embodiment. The control device 100 of the vehicle recording device 10 according to the fourth embodiment includes a captured data acquisition unit 120, a buffer memory 121, a captured data processing unit 122, a recording control unit 123, an operation control unit 124, an event detection unit 125, a communication control unit 126, an access control unit 127, and a position information acquisition unit 128, and further includes a vehicle state determination unit 129.

[0132] The vehicle state determination unit 129 can determine the state of the vehicle equipped with the vehicle recording device 10, specifically, whether the vehicle is stopped. The vehicle state determination unit 129 determines whether the vehicle is stopped based on the change of the position information of the vehicle output from the position information acquisition unit 128, and the position information acquisition unit 128 acquires the position information of the vehicle based on, for example, the output from the GNSS receiving unit 260. That is, the vehicle state determination unit 129 determines that the vehicle is traveling when the position information of the vehicle output from the position information acquisition unit 128 continues to change. On the other hand, when the position information of the vehicle output from the position information acquisition unit 128 does not change for a certain period of time, the vehicle state determination unit 129 determines that the vehicle is stopped.

[0133] Thus, in the vehicle recording device 10 according to the fourth embodiment having the vehicle state determination unit 129, when the vehicle state determination unit 129 determines that the vehicle is stopped, the access control unit 127 permits the unregistered terminal 420 to access the event recording data 320 stored in the recording unit 220. On the other hand, when the vehicle state determination unit 129 determines that the vehicle is not stopped, the access control unit 127 does not permit the unregistered terminal 420 to access the event recording data 320.

[0134] In addition, the vehicle state determination unit 129 may determine whether the vehicle is stopped using information other than the vehicle position information output from the position information acquisition unit 128. The vehicle state determination unit 129 may determine whether the vehicle is stopped based on information related to vehicle travel obtained from a CAN (Controller Area Network) provided by the vehicle, for example.

[0135] <Effect>

[0136] As described above, in the fourth embodiment, when the vehicle state determination unit 129 determines that the vehicle is stopped, the access control unit 127 allows the unregistered terminal 420 to access the event log data 320. Therefore, the unregistered terminal 420 can access the event log data 320 only when a major event occurs.

[0137] That is, the event detection unit 125 detects events based on the acceleration detected by the sensor 240, and therefore may detect matters other than accidents such as emergency braking during vehicle travel as events. In this case, the vehicle does not stop but continues to travel, but while the vehicle is traveling, if the unregistered terminal 420 can access the event record data 320, passengers other than the driver of the vehicle can confirm the event record data 320 related to such events other than accidents through the unregistered terminal 420. As a result, a third party can confirm the event record data 320 other than major events such as vehicle accidents through the unregistered terminal 420, and thus it may be difficult to protect the privacy of the user.

[0138] On the other hand, when the vehicle state determination unit 129 determines that the vehicle has stopped, if the unregistered terminal 420 is allowed to access the event record data 320, the event record data 320 can be confirmed through the unregistered terminal 420 only when a major event such as an accident that makes it difficult to travel or requires the vehicle to stop occurs. As a result, a third party cannot confirm the event record data 320 when a minor event is detected, and can confirm the event record data 320 through the unregistered terminal 420 only when a major event such as a vehicle accident occurs, thereby confirming the cause of the event through the unregistered terminal 420. As a result, privacy protection can be more reliably ensured, and information related to the event can be confirmed.

[0139] [Fifth Embodiment]

[0140] The vehicle recording device 10 according to the fifth embodiment is substantially the same structure as the vehicle recording device 10 according to the first embodiment, and is characterized in that the communication unit 250 and the communication terminal 400 can communicate with each other through a plurality of communication methods, and the control is different according to the communication method. The other structures are the same as those of the first embodiment, and therefore the description thereof is omitted, and the same reference numerals are given.

[0141] Fig.10 1 is a block diagram showing a configuration example of a vehicle recording device 10 according to a fifth embodiment. In the vehicle recording device 10 according to the fifth embodiment, the communication unit 250 includes a first communication unit 251 and a second communication unit 252 that communicate with an external communication terminal 400 in different communication methods. The first communication unit 251 can communicate with the communication terminal 400 in a first communication method, and the second communication unit 252 can communicate with the communication terminal 400 in a second communication method that is different from the first communication method.

[0142] The first communication method, which is a communication method used in the first communication unit 251, can only establish a communication connection with a communication terminal 400 that has been authenticated for communication. The communication authentication is performed, for example, using a password, and in the fifth embodiment, the first communication method is Wi-Fi (registered trademark) with authentication, and self-organizing mode communication based on Wi-Fi is used. On the other hand, the second communication method can establish a communication connection as long as the communication terminal 400 performs communication based on the second communication method. In the fifth embodiment, the second communication method is Bluetooth (registered trademark), for example, NFC (NearField Communication) is used for pairing. In addition, the first communication method may use a communication method other than Wi-Fi, and the second communication method may use a communication method other than Bluetooth.

[0143] Since the first communication method is a communication method for communicating only with the communication terminal 400 that has performed communication authentication, in order to communicate between the communication terminal 400 and the vehicle recording device 10 through the first communication method, an authentication operation for establishing a connection through the first communication method is necessary for any communication terminal 400. In the fifth embodiment, if an authentication operation for establishing a connection through the first communication method is performed once at any communication terminal 400, the communication terminal 400 automatically performs authentication for establishing a connection through the first communication method next time and thereafter.

[0144] Here, the registration terminal 410 is a communication terminal 400 that is registered by performing an input operation related to registration on the operation unit 230. Therefore, when the communication terminal 400 used by the driver of the vehicle is registered as the registration terminal 410, it is assumed that the registration terminal 410 performs an authentication operation for establishing a connection through the first communication method. That is, it is assumed that the registration terminal 410 is used as a communication terminal 400 that can communicate through the first communication method. Therefore, in the following description, the registration terminal 410 is also described as a communication terminal 400 that can communicate through the first communication method. That is, the registration terminal 410 is a terminal held by the owner or user of the vehicle recording device 10 or the vehicle equipped with the vehicle recording device 10.

[0145] On the other hand, the second communication method used in the second communication unit 252 can establish a communication connection if the communication terminal 400 performs communication based on the second communication method. Therefore, if the unregistered terminal 420 is a communication terminal 400 that performs communication based on the second communication method, the unregistered terminal 420 can establish a communication connection based on the second communication method. In addition, if the registered terminal 410 is a communication terminal 400 that performs communication based on the second communication method, the registered terminal 410 can also establish a communication connection based on the second communication method. That is, the unregistered terminal 420 is a terminal owned by an arbitrary third party, and is a terminal other than the registered terminal 410.

[0146] Thus, the communication control unit 126 establishes a connection with the registered terminal 410 based on the first communication method in the first communication unit 251 and a connection with at least the unregistered terminal 420 based on the second communication method in the second communication unit 252, and the communication control unit 126 establishes a connection with the communication terminal 400, which communicates with the communication unit 250.

[0147] Fig.11 1 is a flowchart showing a processing flow related to access to the captured data 300 in the communication terminal 400 in the vehicle recording device 10 according to the fifth embodiment. In the vehicle recording device 10 according to the fifth embodiment, first, it is determined whether there is a connection request based on the first communication method from the communication terminal 400 (step S301). Specifically, the control device 100 determines whether there is a connection request based on the first communication method from the communication terminal 400 for the communication control unit 126 that controls the communication with the communication terminal 400 via the first communication unit 251. That is, the first communication unit 251 determines whether a signal of the connection request from the communication terminal 400 is received.

[0148] Through this determination, when it is determined that there is a connection request based on the first communication method from the communication terminal 400 for the communication control unit 126 or the first communication unit 251 (step S301: "Yes" determination), the communication control unit 126 establishes a connection with the communication terminal 400 based on the first communication method. In addition, in this case, the access control unit 127 allows the communication terminal 400 that has established a connection based on the first communication method to access the normal record data 310 and the event record data 320 (step S302). That is, assuming that the communication terminal 400 that has established a connection based on the first communication method is a registered terminal 410, the access control unit 127 allows the communication terminal 400 to access all the captured data 300 stored in the recording unit 220. As a result, the communication terminal 400 that has established a connection based on the first communication method can confirm the normal record data 310 and the event record data 320.

[0149] On the other hand, when it is determined that there is no connection request based on the first communication method from the communication terminal 400 for the communication control unit 126 or the first communication unit 251 (step S301: "No" determination), it is determined whether there is a connection request based on the second communication method from the communication terminal 400 (step S303). Specifically, the control device 100 determines whether there is a connection request based on the second communication method from the communication terminal 400 for the communication control unit 126 that controls the communication with the communication terminal 400 via the second communication unit 252. That is, the second communication unit 252 determines whether a signal of a connection request from the communication terminal 400 is received.

[0150] Through this determination, when it is determined that there is a connection request based on the second communication method from the communication terminal 400 for the communication control unit 126 or the second communication unit 252 (step S303: "Yes" determination), the communication control unit 126 establishes a connection with the communication terminal 400 based on the second communication method. In addition, in this case, the access control unit 127 allows access to the event log data 320 for the communication terminal 400 that has established a connection based on the second communication method (step S304). That is, it is assumed that the communication terminal 400 that has established a connection based on the second communication method is an unregistered terminal 420, and the access control unit 127 does not allow access to the normal log data 310 in the captured data 300 stored in the recording unit 220, but allows access to the event log data 320. As a result, the communication terminal 400 that has established a connection based on the second communication method can only confirm the event log data 320.

[0151] Thus, if the access of the communication terminal 400 to the photographic data 300 is restricted according to the communication method when the connection is established, then it is determined whether the connection of the communication terminal 400 is terminated (step S305). Specifically, the control device 100 determines whether the connection establishment between the communication terminal 400 and the communication control unit 126 is continued via the communication unit 250.

[0152] Through this determination, when it is determined that the connection between the communication terminal 400 and the communication control unit 126 is continuing and the connection of the communication terminal 400 has not been terminated (step S305: "No" determination), the state of allowing access in step S302 or step S304 is maintained, and the determination of whether the connection of the communication terminal 400 has been terminated is repeated.

[0153] In contrast, when it is determined that the connection between the communication terminal 400 and the communication control unit 126 is terminated and the connection of the communication terminal 400 has been terminated (step S305: "Yes" judgment), the processing related to the connection with the communication terminal 400 is terminated, and when the processing is called again, it starts again from step S301.

[0154] In addition, with respect to these, when it is determined that there is no connection request based on the second communication method from the communication terminal 400 for the communication control unit 126 or the second communication unit 252 (step S303: "No" determination), it is determined whether to end (step S306). In other words, it is determined whether the operation of the vehicle recording device 10 or the communication control with the communication terminal 400 is ended. Through this determination, when it is determined that the operation of the vehicle recording device 10 or the communication control with the communication terminal 400 is not ended (step S306: "No" determination), it returns to step S301 and determines again whether there is a connection request based on the first communication method.

[0155] In contrast, when it is determined that the operation of the vehicle recording device 10 or the communication control with the communication terminal 400 is terminated (step S306: "Yes" determination), at least the processing related to the connection with the communication terminal 400 is terminated, and when the processing is called again, it starts again from step S301.

[0156] <Effect>

[0157] As described above, in the fifth embodiment, access control of the communication terminal 400 to the photographed data 300 is performed according to the communication method when establishing a connection with the communication terminal 400, so that access control can be performed more reliably. That is, in the communication control unit 126, a connection with the registered terminal 410 based on the first communication method and a connection with at least the unregistered terminal 420 based on the second communication method are established, and access control is performed according to the communication method, thereby making it possible to more reliably prevent the unregistered terminal 420 from accessing the normal recorded data 310 but accessing the event recorded data 320. As a result, information related to the event can be confirmed while ensuring privacy protection.

[0158] [Modification of the Fifth Embodiment]

[0159] In addition, in the fifth embodiment, the registered terminal 410 can not only confirm the connection through the first communication method, but also establish the connection through the second communication method, so it is also considered that the connection is established through the second communication method. Therefore, it is also possible to determine whether the communication terminal 400 connected through the second communication method is the registered terminal 410 or the unregistered terminal 420.

[0160] Fig.12 1 is a flowchart showing a processing flow related to access to the captured data 300 in the communication terminal 400 in the vehicle recording device 10 according to the modification of the fifth embodiment. In the modification of the fifth embodiment, when it is determined that there is a connection request based on the second communication method from the communication terminal 400 to the communication control unit 126 or to the second communication unit 252 (step S303: "Yes" determination), the communication control unit 126 establishes a connection with the communication terminal 400 based on the second communication method. Furthermore, the control device 100 determines whether the communication terminal 400 to which the connection based on the second communication method has been established is a pre-registered communication terminal 400 (step S311). In detail, the control device 100 determines whether the communication terminal 400 to which the connection based on the second communication method has been established is a pre-registered registered terminal 410 or an unregistered terminal 420 that has not been pre-registered through the communication control unit 126.

[0161] Through this determination, when it is determined that the communication terminal 400 that has established a connection using the second communication method is a pre-registered registered terminal 410 (step S311: "Yes" determination), the registered terminal 410 is allowed to access the normal log data 310 and the event log data 320 (step S302). That is, when the communication terminal 400 that has established a connection using the second communication method through the communication control unit 126 is the registered terminal 410, the access control unit 127 can allow the registered terminal 410 to access the normal log data 310 and the event log data 320.

[0162] In contrast, when it is determined that the communication terminal 400 that has established a connection based on the second communication method is not a pre-registered registration terminal 410 (step S311: "No" judgment), the access control unit 127 does not allow access to the normal record data 310 for the communication terminal 400 that has established a connection based on the second communication method, but allows access to the event record data 320 (step S304).

[0163] <Effect>

[0164] As described above, in the modified example of the fifth embodiment, when the communication terminal 400 that has established a connection through the second communication method is the registration terminal 410, the registration terminal 410 can access the normal record data 310 and the event record data 320, so the convenience of use can be improved. That is, the registration terminal 410 can connect to the communication unit 250 not only through the first communication method, but also through the second communication method, so sometimes the connection is established through the second communication method. Even in such a case, it is determined whether the communication terminal 400 that has established a connection through the second communication method is the registration terminal 410, thereby avoiding the situation that the registration terminal 410 cannot access the normal record data 310. As a result, the convenience of use when the information related to the event can be confirmed can be improved while ensuring the protection of privacy.

[0165] [Sixth Embodiment]

[0166] The vehicle recording device 10 according to the sixth embodiment has a substantially similar structure to the vehicle recording device 10 according to the fifth embodiment, but is characterized in that, after a connection request based on the second communication method is made, access to the event recording data 320 is permitted only within a predetermined period from the detection of an event. The other structures are the same as those of the fifth embodiment, and therefore description thereof is omitted, and the same reference numerals are used.

[0167] In the vehicle recording device 10 according to the sixth embodiment, the access control unit 127 of the control device 100 allows the communication terminal 400 connected by the second communication method to access the event record data 320 during a predetermined period after the event detection unit 125 detects the event. If the predetermined period has passed since the event detection unit 125 detected the event, the access control unit 127 does not allow the communication terminal 400 connected by the second communication method to access the event record data 320. The predetermined period in this case is preset and stored in, for example, the internal memory of the control device 100.

[0168] That is, in the sixth embodiment, unlike the fifth embodiment, a restriction is set on the period during which the communication terminal 400 connected by the second communication method can access the event log data 320. Therefore, in the sixth embodiment, the communication terminal 400 connected by the second communication method can access the event log data 320 only within a predetermined period after the event detection unit 125 detects the event. In other words, if the predetermined period has passed after the event detection unit 125 detects the event, the communication terminal 400 connected by the second communication method cannot access any captured data 300 stored in the recording unit 220 including the event log data 320.

[0169] Fig.13 1 is a flowchart showing a processing flow related to access to the captured data 300 in the communication terminal 400 in the vehicle recording device 10 according to the sixth embodiment. In the sixth embodiment, when it is determined that there is a connection request based on the second communication method from the communication terminal 400 for the communication control unit 126 or the second communication unit 252 (step S303: "Yes" determination), it is determined whether it is within a prescribed period from the detection of the event (step S321). In detail, when the second communication unit 252 has established a connection with the communication terminal 400 through the second communication method, the control device 100 first determines whether it is within a prescribed period pre-set from the detection of the event by the event detection unit 125.

[0170] Through this determination, if it is determined that it is within the prescribed period from the detection of the event (step S321: "Yes" determination), the access control unit 127 permits the communication terminal 400 that has established a connection based on the second communication method to access the event log data 320 (step S304). That is, if it is determined that it is within the prescribed period from the detection of the event, the communication terminal 400 that has established a connection based on the second communication method is an unregistered terminal 420, and the access control unit 127 does not permit the communication terminal 400 to access the normal log data 310 but permits the communication terminal 400 to access the event log data 320.

[0171] On the other hand, if it is determined that it is not within the predetermined period from the event detection (step S321: No determination), it is determined whether to end (step S306). That is, it is determined whether the operation of the vehicle recording device 10 or the communication control with the communication terminal 400 is ended.

[0172] <Effect>

[0173] As described above, in the sixth embodiment, after the connection with the communication terminal 400 based on the second communication method is established, the access control unit 127 allows access to the event log data 320 only within a prescribed period from the detection of the event by the event detection unit 125, and does not allow access to the event log data 320 when the prescribed period is exceeded. Thus, when a long time has passed since the occurrence of an event such as a vehicle accident, it is possible to prevent a third party from accessing the event log data 320 through the communication terminal 400 to which the connection has been established by the second communication method, that is, the unregistered terminal 420. Therefore, it is possible to prevent an event that has passed since the occurrence of the event from being accidentally known to a third party, and the privacy of the user can be more reliably protected.

[0174] On the other hand, after the event is detected, the unregistered terminal 420 connected by the second communication method can access the event log data 320 within a predetermined period. Therefore, within the predetermined period, the third party can easily confirm the event log data 320 recorded when the event occurred through the unregistered terminal 420. As a result, after an event such as a vehicle accident occurs, within the predetermined period, the cause of the event can be easily confirmed using the unregistered terminal 420 connected by the second communication method. As a result, information related to the event can be confirmed while ensuring privacy protection.

[0175] [Modification of the Sixth Embodiment]

[0176] In addition, in the sixth embodiment, for the communication terminal 400 that has established a connection through the second communication method, access to the event log data 320 is allowed only during a specified period after the event detection unit 125 detects an event, but in this case, the event log data 320 that is allowed to be accessed may also be the most recent event log data 320a. That is, for the communication terminal 400 that has established a connection through the second communication method, even within a specified period after the event detection unit 125 detects an event, access to event log data 320 other than the most recent event log data 320a may not be allowed, and access to only the most recent event log data 320a may be allowed. Thus, even if a plurality of event log data 320 are stored in the recording unit 220, it is possible to prevent a third party from confirming event log data 320 other than the most recent event log data 320a through the communication terminal 400 that has established a connection through the second communication method. Therefore, it is possible to prevent an event that occurred in the vehicle in the past from being accidentally known to a third party, and the user's privacy can be more reliably protected.

[0177] [Seventh Embodiment]

[0178] The vehicle recording device 10 involved in the seventh embodiment is substantially the same structure as the vehicle recording device 10 involved in the sixth embodiment, but its feature is that connection based on the second communication method is allowed only within a predetermined period from the detection of an event. The other structures are the same as those in the sixth embodiment, so their description is omitted and the same reference numerals are marked.

[0179] In the vehicle recording device 10 according to the seventh embodiment, the communication control unit 126 does not establish a connection with the communication terminal 400 based on the second communication method during a period in which the event detection unit 125 does not detect an event, and enables establishment of a connection with the communication terminal 400 based on the second communication method during a predetermined period after the event detection unit 125 detects an event. In this case, the predetermined period in this case is preset and stored in, for example, an internal memory of the control device 100.

[0180] That is, the communication control unit 126 allows the connection with the communication terminal 400 only in the first communication mode during the period when the event detection unit 125 does not detect an event. Therefore, during the period when the event detection unit 125 does not detect an event, the communication control unit 126 substantially only allows the connection of the registered terminal 410 and does not allow the connection of the unregistered terminal 420.

[0181] Fig.14 4 is a flowchart showing a process flow related to access to the photographed data 300 at the communication terminal 400 in the vehicle recording device 10 according to the seventh embodiment. In the vehicle recording device 10 according to the seventh embodiment, first, a connection based on the first communication method is allowed (step S401). Thus, the connection of the unregistered terminal 420 is substantially not allowed, and only the registered terminal 410 registered in advance is allowed to connect.

[0182] Next, the event detection unit 125 determines whether an event to the vehicle is detected (step S402). That is, the event detection unit 125 detects the occurrence of an event based on whether the acceleration detected by the sensor 240 is equal to or greater than a preset threshold.

[0183] In this way, when the event detection unit 125 that detects events based on the acceleration detected by the sensor 240 detects that an event has occurred to the vehicle (step S402: "Yes" determination), the control device 100 allows connection based on the second communication method for a predetermined period from the detection of the event (step S403). As a result, the communication terminal 400 that can connect based on the second communication method, including the unregistered terminal 420, becomes in a state where it can connect based on the second communication method.

[0184] Next, it is determined whether there is a connection request using the second communication method from communication terminal 400 (step S404). That is, second communication unit 252 communicating with communication terminal 400 using the second communication method determines whether a connection request signal from communication terminal 400 is received.

[0185] Through this determination, when it is determined that there is a connection request based on the second communication method from the communication terminal 400 (step S404: "Yes" determination), the communication control unit 126 establishes a connection with the communication terminal 400 based on the second communication method. Furthermore, the control device 100 determines whether the communication terminal 400 that has established a connection based on the second communication method is a pre-registered communication terminal 400 (step S405). That is, the control device 100 determines whether the communication terminal 400 that has established a connection based on the second communication method is a pre-registered registered terminal 410 or an unregistered terminal 420 that has not been pre-registered.

[0186] Through this determination, when it is determined that the communication terminal 400 that has established a connection based on the second communication method is a pre-registered registered terminal 410 (step S405: "Yes" determination), the access control unit 127 allows the registered terminal 410 to access the normal log data 310 and the event log data 320 (step S406).

[0187] In contrast, when it is determined that the communication terminal 400 that has established a connection based on the second communication method is not a pre-registered registered terminal 410 (step S405: "No" judgment), for the communication terminal 400 that has established a connection based on the second communication method, the access control unit 127 does not allow access to the normal record data 310 but allows access to the event record data 320 (step S407).

[0188] As described above, if the access of the communication terminal 400 to the photographed data 300 is restricted according to whether the communication terminal 400 that has established the connection based on the second communication method is the pre-registered registered terminal 410, then it is determined whether the connection of the communication terminal 400 is terminated (step S408). Specifically, the control device 100 determines whether the establishment of the connection between the communication terminal 400 and the communication control unit 126 is continued via the communication unit 250.

[0189] Through this judgment, when it is determined that the connection establishment between the communication terminal 400 and the communication control unit 126 is continuing and the connection of the communication terminal 400 has not been terminated (step S408: "No" judgment), the state of allowing access in step S406 or step S407 is maintained, and the judgment of whether the connection of the communication terminal 400 is terminated is repeated.

[0190] In contrast, when it is determined that the connection between the communication terminal 400 and the communication control unit 126 is terminated and the connection of the communication terminal 400 has been terminated (step S408: "Yes" judgment), the processing related to the connection of the communication terminal 400 is terminated, and when the processing is called again, it starts again from step S401.

[0191] On the other hand, when it is determined that the event detection unit 125 has not detected that an event has occurred with respect to the vehicle (step S402: "No" determination), and when there is no connection request based on the second communication method from the communication terminal 400 (step S404: "No" determination), it is determined whether to end (step S409). That is, it is determined whether the operation of the vehicle recording device 10 or the communication control with the communication terminal 400 has ended. Through this determination, when it is determined that the operation of the vehicle recording device 10 or the communication control with the communication terminal 400 has not ended (step S409: "No" determination), the process returns to step S402 to determine whether an event with respect to the vehicle has been detected.

[0192] In contrast, when it is determined that the operation of the vehicle recording device 10 or the communication control with the communication terminal 400 has ended (step S409: "Yes" judgment), the processing related to at least the connection with the communication terminal 400 is ended, and when the processing is called again, it starts again from step S401.

[0193] <Effect>

[0194] As described above, in the seventh embodiment, the establishment of the connection with the communication terminal 400 based on the second communication method is enabled only within a predetermined period from the time when the event detection unit 125 detects an event, so that the establishment of the connection with the communication terminal 400 based on the second communication method can be suppressed when no event is detected. In other words, when the event detection unit 125 does not detect an event, it is substantially possible to enable only the establishment of the connection with the registered terminal 410 based on the first communication method, and prohibit the establishment of the connection with the unregistered terminal 420 based on the second communication method. Thus, when an event such as a vehicle accident does not occur, it is possible to suppress a third party from accessing the event log data 320 through the unregistered terminal 420 when the connection with the unregistered terminal 420 is established by the second communication method. Therefore, when no event occurs, it is possible to suppress the event log data 320 from being accidentally confirmed by a third party, and the privacy of the user can be more reliably protected.

[0195] On the other hand, after the event is detected, in order to make the establishment of the connection with the communication terminal 400 based on the second communication method effective within the prescribed period, after the event is detected, if within the prescribed period, the connection of the unregistered terminal 420 is established through the second communication method, and the third party can confirm the event log data 320 recorded when the event occurs through the unregistered terminal 420. As a result, after an event such as a vehicle accident occurs, if within the prescribed period, the cause of the event can be easily confirmed through the unregistered terminal 420. As a result, information related to the event can be confirmed while ensuring privacy protection.

[0196] In addition, in the above-mentioned first to seventh embodiments, although the shooting data 300 saved as event recording data 320 upon event detection is illustrated as a method of saving one shooting data 300 as event recording data 320 upon one event detection, it is also possible to save multiple shooting data 300 as event recording data 320 upon one event detection.

[0197] [Other embodiments]

[0198] On the basis of the above-mentioned embodiment, the vehicle recording device 10 involved in this embodiment is implemented in various different ways. For example, in the case where a connection with an unregistered terminal 420 has been established, the access control unit 127 of the control device 100 can make accessible the event recording data with an acceleration greater than a specified value when the event is detected, among the event recording data most recently saved, such as 5 minutes before the connection is established. The specified value in this case is set to a value that is obviously caused by a collision of the vehicle. In the case where a connection with an unregistered terminal 420 has been established, the access control unit 127 of the control device 100 can make accessible the event recording data with the largest acceleration when the event is detected, among the event recording data most recently saved, such as 5 minutes before the connection is established. By performing such processing, even if event recording data is saved due to acceleration applied to the vehicle before and after the accident, a third party can use the unregistered terminal 420 to confirm the event recording data related to the accident.

[0199] Although the vehicle recording device 10 according to this embodiment has been described above, the vehicle recording device 10 may be implemented in various different forms other than the first to seventh embodiments described above.

[0200] The components of the vehicle recording device 10 shown in the figure are conceptual functions and do not need to be physically configured as shown in the figure. That is, the specific form of each device is not limited to the form shown in the figure, and all or part of them may be functionally or physically dispersed or integrated in arbitrary units according to the processing load of each device, usage conditions, etc.

[0201] The structure of the vehicle recording device 10 is realized by, for example, a program loaded into a memory as software. In the above embodiment, the functional blocks realized by the cooperation of these hardware or software are described. That is, these functional blocks can be realized in various forms only by hardware, only by software, or by a combination of these.

[0202] The above-mentioned constituent elements include elements that can be easily thought of by those skilled in the art, and substantially the same elements. Furthermore, the above-mentioned structures can be appropriately combined. In addition, various omissions, substitutions or changes of the structure can be performed within the scope of the gist of the present invention.

[0203] In the above description, a case where loop recording processing is performed is described, but the same is true for a case where imaging is started after an event is detected.

[0204] In the above description, although the camera unit 210 is arranged near the front glass in the vehicle compartment to capture the surrounding conditions centered on the front of the vehicle, the camera unit 210 is not limited to this, and can also be arranged near the rear glass of the vehicle facing backward to capture the surrounding conditions centered on the rear of the vehicle. Alternatively, the camera unit 210 can also be a camera that can capture 360° around, or a plurality of camera groups that capture in different directions.
