The present invention is not limited to the embodiments shown below.

<Outline of recording method of drive recorder>
FIG. 1 is a diagram showing an outline of a recording method of a drive recorder according to an embodiment. The drive recorder recording method according to the embodiment is executed by, for example, the drive recorder 1 mounted on the vehicle 11.

Note that FIG. 1 shows a case where the passenger A gets on the vehicle 11. The passenger A is, for example, the driver of the vehicle 11, but is not limited to the driver, and may be a passenger seated in the passenger seat or the rear seat of the vehicle 11.

In the recording method of the drive recorder 1 according to the embodiment, the access right is given to the passenger A of the vehicle 11 for the traveling image obtained by capturing the outside of the vehicle 11, while the access restriction that restricts the access other than the passenger A. To set. Further, when a predetermined event such as a collision accident of the vehicle 11 occurs, the access restriction is released.

Specifically, as shown in FIG. 1, the drive recorder 1 first has a predetermined frame rate (unit time) outside the vehicle 11 by an imaging unit (not shown) provided on the drive recorder 1 itself or the vehicle 11. Image is taken with the number of processing frames per process). For example, the traveling image V1 captured by the imaging unit is set with access restrictions that restrict access from other than the passenger A, and is recorded in the storage medium as traveling information F1.

The traveling information F1 is information including identification information for identifying the passenger A. The identification information includes, for example, an ID for identifying passenger A, a password for permitting access to the driving information F1 (“1234” in the example of FIG. 1), information about an administrator having administrator authority, and the like. included.

That is, the drive recorder 1 records the traveling information F1 that restricts access from other than the passenger A by giving a password to the traveling video V1. As a result, the traveling image V1 when the passenger A boarded the vehicle 11 cannot be viewed by another person (viewer B in the example of FIG. 1) who does not know the password of the passenger A, and thus the individual passenger A. Information is protected.

The access restriction is not limited to the password, and fingerprint authentication for collating the fingerprint received from the passenger A with the fingerprint information may be used, for example, by including the fingerprint information of the passenger A in the identification information. ..

On the other hand, when the vehicle 11 causes a collision accident with another vehicle, for example, if an access restriction is set to restrict access from a vehicle other than the passenger A to the traveling image V2 of the collision accident, the police or an insurance company The viewer B, for example, cannot view the traveling image V2 in which the situation of the collision accident is captured, and may not be able to accurately analyze the cause of the accident.

Therefore, in the recording method of the drive recorder 1 according to the embodiment, when the event generated with respect to the vehicle 11 satisfies at least a predetermined condition indicating a high degree of urgency, the traveling in which the access restriction from other than the passenger A is released is released. It was decided to record the information F2.

As a result, according to the recording method of the drive recorder 1 according to the embodiment, for example, the personal information of the passenger A is protected for the less urgent driving image, and the other than the passenger A for the more urgent driving image. But you will be able to browse. That is, since the reader B such as the police or the insurance company can view the driving image V2 of the collision accident recorded in the driving information F2, the cause of the accident can be accurately analyzed.

<Overview of display system>
Next, the display system 100 including the drive recorder 1 described with reference to FIG. 1 will be described with reference to FIG. FIG. 2 is a diagram showing an outline of the display system 100 according to the embodiment. As shown in FIG. 2, the display system 100 according to the embodiment includes portable devices P1 to Pn, a drive recorder 1, and a display device 10. In the following, when the portable devices P1 to Pn are generically referred to, they are referred to as the portable device P.

The portable device P is, for example, a portable electronic device such as a mobile phone or a smartphone owned by a passenger of the vehicle 11. The portable device P is not limited to a mobile phone or a smartphone, and may be an electronic key that controls the unlocking of the door of the vehicle 11 or the start of the engine, as long as the passenger can be identified.

The portable device P is communicably connected to the drive recorder 1. For example, the portable device P and the drive recorder 1 wirelessly communicate with each other to send and receive identification information, an authentication request, an authentication result, and the like. For wireless communication, for example, Bluetooth (registered trademark) and WiFi (registered trademark), which are short-range wireless communication standards for digital devices, are used.

The drive recorder 1 is provided with an image pickup unit (not shown), and a portion where the outside of the vehicle 11 can be imaged by the image pickup unit, for example, a windshield vehicle interior so that the image pickup direction of the image pickup unit faces the front of the vehicle 11. Provided on the inner surface.

In addition to the windshield, the drive recorder 1 can be installed at any place such as the rear glass of the vehicle 11, the ceiling in the vehicle interior, the dashboard, or any other place where the outside of the vehicle 11 can be imaged. Further, the image pickup unit may be separated from the drive recorder 1, and the image pickup section may be installed at an arbitrary position on the vehicle 11 according to the image pickup direction.

Further, a portable storage medium M (for example, an SD card) can be attached to and detached from the drive recorder 1. The storage medium M records travel information including travel images for which access restrictions are set.

The storage medium M is not limited to the portable storage medium, and may be, for example, an HDD (Hard Disk Drive) built in the drive recorder 1 or a server device in cloud computing. Good.

The display device 10 includes, for example, a display, and causes such a display to display a traveling image recorded on the storage medium M. Further, the display device 10 includes an input unit (not shown) for inputting a password or the like set in the travel information. In the display device 10, the portable device P may also have the function of the display device 10.

<Display system block diagram>
The configuration of the display system 100 will be described more specifically with reference to FIG. FIG. 3 is a block diagram showing the configuration of the display system 100 according to the embodiment.

<Mobile device P>
The portable device P performs initial settings for registering the passenger A as an authentication target by transmitting the identification information that identifies the passenger A to the drive recorder 1. In such an initial setting, the passenger A sets, for example, an arbitrary character string that can identify the passenger A as the ID and the password that are the identification information.

Further, when the passenger A whose initial setting has been completed boarded the vehicle 11, the portable device P transmits an authentication request for personally authenticating the passenger A to the drive recorder 1. The authentication request requests authentication by, for example, transmitting the ID and password registered in the initial settings. When the drive recorder 1 authenticates the transmitted ID and password of the passenger A, the portable device P receives the authentication result from the drive recorder 1.

<Vehicle 11>
The vehicle 11 includes a drive recorder 1 and a vehicle sensor 3. First, the vehicle sensor 3 will be described. The vehicle sensor 3 is a sensor that detects a state related to the running of the vehicle 11.

The vehicle sensor 3 includes, for example, an acceleration sensor that detects the acceleration of the vehicle 11, a sensor that detects the distance between the vehicle 11 and another vehicle by a millimeter-wave radar that emits radio waves, a security sensor that detects the theft of the vehicle 11, and the like. Is. The vehicle sensor 3 outputs a detection result indicating the state of the vehicle 11 to the drive recorder 1.

<Drive recorder 1>
The drive recorder 1 includes an imaging unit 2, a control unit 4, and a storage unit 5. The control unit 4 includes an authentication unit 4a and an access control unit 4b.

The image pickup unit 2 includes, for example, an image pickup device such as a CCD (Charge Coupled Device) or a CMOS (Complementary Metal Oxide Semiconductor). The image pickup unit 2 outputs an image captured by the image pickup element to the outside of the vehicle 11 at a predetermined frame rate (for example, 30 fps) as a running image to the control unit 4.

The control unit 4 is, for example, a microcomputer including a CPU (Central Processing Unit), a RAM (Random Access Memory), and a ROM (Read Only Memory). Such a CPU functions as the above-mentioned authentication unit 4a and access control unit 4b by performing arithmetic processing according to, for example, a program stored in advance in the ROM.

<Authentication unit 4a>
The authentication unit 4a stores the identification information 5a including the ID and password for identifying the passenger A, which is transmitted from the mobile device P in the initial setting, in the storage unit 5. Further, when the passenger A gets on the vehicle 11, the authentication unit 4a receives an authentication request from the portable device P and performs personal authentication of the passenger A based on the ID and password for identifying the passenger A.

Specifically, the authentication unit 4a determines whether or not the ID and password transmitted from the portable device P and the ID and password of the identification information 5a stored in the storage unit 5 match. When both IDs and passwords match, the authentication unit 4a authenticates the passenger A and transmits an authentication result indicating the authentication to the mobile device P.

Here, the identification information 5a stored by the authentication unit 4a will be described with reference to FIG. FIG. 4 is a diagram showing the identification information 5a. The identification information 5a shown in FIG. 4 is an example, and the present invention is not limited to this.

As shown in FIG. 4, the identification information 5a is information including items such as "ID", "password", "administrator flag", and "quasi-administrator flag". The "ID" is information that identifies a passenger boarding the vehicle 11, such as a user name. The "password" is a password for permitting access, and is composed of, for example, any four numbers.

The "administrator flag" and the "quasi-administrator flag" indicate whether the administrator is an administrator who can execute a privileged function for processing the driving information and an equivalent quasi-administrator, whichever is "0" or "1". Information indicated by a value. That is, when the authentication target person is registered as an administrator or a quasi-administrator, the "administrator flag" or the "quasi-administrator flag" is "1", respectively. The administrator and the quasi-administrator will be described later with reference to FIG.

As shown in FIG. 4, a plurality of certifiers can be registered in the identification information 5a. For example, the identification information 5a is one vehicle 11 when the vehicle 11 is a rental car, a company car, or the like. Indicates that can be shared by multiple certifiers. That is, each certifier restricts access from anyone other than the person himself / herself by setting a different password.

Returning to FIG. 3, the description of the authentication unit 4a will be continued. When the authentication unit 4a authenticates the passenger A, the authentication result is transmitted to the mobile device P, and the information about the passenger A included in the identification information 5a is output to the access control unit 4b.

<Access control unit 4b>
The access control unit 4b grants the passenger A an access right to the traveling image input from the imaging unit 2 based on the information about the passenger A acquired from the authentication unit 4a, and also from a person other than the passenger A. Restrict access Set access restrictions. Specifically, the access control unit 4b sets the access restriction by assigning the password of the passenger A acquired from the authentication unit 4a to the traveling image. Further, the access control unit 4b releases the access restriction to the traveling image by canceling or not assigning the password to the traveling image.

Here, the process of setting the access restriction will be described with reference to FIG. FIG. 5 is a diagram illustrating a process of setting an access restriction. As shown in FIG. 5, the drive recorder 1 according to the embodiment uses, for example, a constant recording method in which captured images G input from the imaging unit 2 are sequentially recorded.

In such a method, the access control unit 4b sets access restrictions for each captured image sequentially input from the imaging unit 2. Specifically, when the captured image G1 is imaged at the time t1 when the passenger A is authenticated, the access control unit 4b has a password (for example, 1234) corresponding to the ID of the passenger A with respect to the captured image G1. ) Is given.

When the passenger A gets off the vehicle 11, that is, when the communication between the portable device P of the passenger A and the drive recorder 1 is interrupted, the access control unit 4b cancels the authentication of the passenger A and performs such authentication. The password corresponding to the ID of passenger A is not given to the captured image after the release.

Then, the access control unit 4b stores each captured image to which the password corresponding to the ID of the passenger A is given in, for example, a folder FA for storing the traveling information regarding the passenger A. That is, in order to view the traveling video stored in the folder FA, a password corresponding to the ID of the passenger A is required.

Further, when the captured image G10 is captured at the time t10 when the passenger B is authenticated, the access control unit 4b assigns a password (for example, 5678) corresponding to the ID of the passenger B to the captured image G10. To do.

The access control unit 4b stores each captured image to which the password corresponding to the ID of the passenger B is given in, for example, the folder FB for storing the traveling information regarding the passenger B. That is, in order to view the traveling video stored in the folder FB, a password corresponding to the ID of the passenger B is required.

As a result, when passenger A and passenger B share the vehicle 11, by setting a password corresponding to each passenger for each traveling image, access without permission from anyone other than the passenger is restricted. can do.

Further, for example, when the passenger B driving the vehicle 11 causes a collision accident at the time t30, the access control unit 4b receives the passenger for the traveling image for a predetermined period including the captured image G30 captured at the time t30. Release the access restriction that restricts access from other than B.

Specifically, the access control unit 4b releases the password assigned to each captured image in the past period from the time t20 to the time t30. Further, the access control unit 4b does not give a password to each captured image in the period from time t30 to time t40.

As a result, a person other than the certifying passenger B (for example, an unauthenticated passenger A or the viewer C) can view the traveling video during the period before and after the collision accident at time t30.

Further, the access control unit 4b stores each captured image for which a password is not set, for example, in a folder F. That is, since a password for viewing the running video stored in the folder F is not required, anyone can view it.

Next, the traveling information 5b stored in the storage unit 5 will be described with reference to FIG. FIG. 6 is a diagram showing traveling information 5b. The traveling information 5b shown in FIG. 6 is an example and is not limited thereto.

As shown in FIG. 6, the traveling information 5b is information including items such as "image No.", "time", "authentication ID", "PW flag", and "password". The "image No." is an identification ID of the captured image, and is, for example, numbering information given to each of the captured images. The "time" is the time when the captured image was captured. The "authentication ID" is the ID of the passenger who has been authenticated at the corresponding time.

The "PW flag" is information indicating whether or not to give a password to the captured image by a binary value of "0" or "1". In the "PW flag", "1" indicating that a password is not assigned is stored when the event occurring for the vehicle 11 satisfies at least a predetermined condition indicating a high degree of urgency, and in other cases Is stored in "0". The "password" is a password corresponding to the passenger of the authentication ID.

For example, when a collision accident occurs at time t30, by setting the PW flag from time t20 to time t40 to "1", a password is not assigned to the captured image of the corresponding "image No."

Further, the access control unit 4b determines whether or not a highly urgent event has occurred with respect to the vehicle 11 in determining whether or not to assign the password. Specifically, the access control unit 4b determines which event has occurred in the event information 5c including the event with high urgency based on the detection result input from the vehicle sensor 3.

Here, the event information 5c will be described with reference to FIG. FIG. 7 is a diagram showing event information 5c. The event information 5c shown in FIG. 7 is stored in advance in the storage unit 5. The event information 5c shown in FIG. 7 is an example and is not limited to this. The event information 5c represents information such as settings related to each of various events that are expected to occur in the vehicle 11. Events that are expected to occur in the vehicle 11 include events with high urgency and events with low urgency.

As shown in FIG. 7, the event information includes items such as "event", "recording start", "presence / absence of PW", "overwrite prevention", and "others". “Event” indicates a pattern of events that can occur around the vehicle 11.

“Recording start” indicates a method of starting recording of the traveling information 5b, and is classified into “automatic” and “manual”. “Automatic” indicates that the driving information 5b is recorded regardless of the intention of the certifier. “Manual” indicates that the traveling information 5b is recorded when a predetermined operation is received from the certifier.

“Presence / absence of PW” indicates whether or not to give a password to the travel information 5b to be recorded. In the case of an event in which "presence or absence of PW" is "none", it means that the password for the driving information 5b is released. Normally, "presence or absence of PW" is "none" for events with high urgency. Further, in the case of a specific event in which "presence or absence of PW" is "selection", an operation from the passenger who selects whether to give or cancel the password to the driving information 5b is accepted, and the password is given and the password is given according to the operation. Cancellation (setting and cancellation of access restrictions) can be switched. The "overwrite prevention" deletes the possibility of overwriting for recording the new driving information 5b, that is, the old driving information 5b, when the recording capacity of the storage unit 5 is insufficient due to the excessive amount of data of the recorded driving information 5b. Indicates whether or not. "Other" indicates other incidental information.

In the drive recorder 1 according to the embodiment, a constant recording method for recording all the captured running images is normally used. That is, the access control unit 4b sets the "constant recording" shown in FIG. 7 as a normal pattern, and in the "constant recording", "presence / absence of PW" is "present", that is, a password is assigned to the traveling information 5b to be recorded.

Further, in the case of "constant recording", the access control unit 4b makes it possible to rewrite the old driving information 5b to the new driving information 5b with respect to the recorded traveling information 5b according to "None" of "Overwrite prevention". As a result, the drive recorder 1 can use the recording capacity of the storage unit 5 without waste.

Next, the case where the event is an "accident impact" will be described as an example. For example, when the vehicle 11 collides with another vehicle and the acceleration sensor, which is the vehicle sensor 3, detects an acceleration equal to or higher than a predetermined threshold value, the access control unit 4b determines that an "accident impact" has occurred as an event.

Then, in such a case, the access control unit 4b releases the password for the travel information 5b to be recorded according to the information corresponding to the "accident impact" in the event information 5c, for example, "None" of "PW presence / absence". Further, the access control unit 4b prevents the travel information 5b to be recorded from being rewritten according to, for example, "Yes" in "Overwrite prevention".

As a result, in the drive recorder 1 according to the embodiment, in the event of a collision accident or the like, a viewer such as a police officer or an insurance company can view the driving information 5b in which the collision accident is reflected. The cause can be analyzed accurately.

The judgment condition when the event is "sudden braking" is, for example, that the forward acceleration detected by the acceleration sensor is equal to or more than a predetermined threshold value and equal to or less than the threshold value of the acceleration determined to be "accident collision". This is the case.

Further, the determination condition when the event is "crime prevention (approaching a suspicious person)" or "crime prevention (vehicle body impact)" is, for example, when the vehicle sensor 3 detects a suspicious person approaching the vehicle 11 or such a suspicious person. Detects breaking the window glass in an attempt to steal the vehicle 11.

Further, as a judgment condition when the event is "when the automatic brake is activated", for example, the vehicle sensor 3 detects that the distance between the vehicle 11 and the vehicle in front is equal to or less than a predetermined distance, and is separately mounted on the vehicle 11. This is the case where the in-vehicle device is automatically controlling the brake. Further, the determination condition when the event is "when the vehicle deviates from the lane" is, for example, when the vehicle sensor 3 detects the deviation from the lane of the vehicle 11.

Further, the determination condition when the event is "when the vehicle is stuck" is, for example, when the vehicle 11 is stuck on a snowy road and the acceleration is not detected even though the engine is rotating at high speed.

Next, the case where "recording start" is "manual" will be described by taking the case where the event is "drive scenery" as an example. For example, when the passenger who is the certifier wants to record and save the scenery during driving, the access control unit 4b performs a predetermined operation corresponding to the recording via a switch provided on the drive recorder 1. If so, the operation is accepted as a "drive scenery" event.

Then, the access control unit 4b causes the passenger to select whether to give or cancel the password to the driving image of the driving scenery according to the information corresponding to the "driving scenery", for example, "selection" of "presence or absence of PW". .. Then, the access control unit 4b switches between granting and canceling the password according to the passenger's selection operation. In addition, according to "Yes" of "Overwrite protection", access restrictions that cannot be deleted are set for the driving image of the driving scenery.

As a result, in the drive recorder 1 according to the embodiment, the passenger can set arbitrary access restrictions to the driving image, for example, the driving image of the driving scenery can be viewed by other viewers without a password. , It can be prevented from being accidentally overwritten and erased.

In addition, as an event when "recording start" is "manual", there are other cases such as "dangerous driving by others", "traffic violation by others", and "accident by others". These do not pose a danger to the vehicle 11 which is the own vehicle, that is, although the urgency is not high, it is optional for the passenger to set access restrictions to the traveling image so that other viewers can view it later. It is possible to set to. That is, the passenger can arbitrarily set an access restriction such as setting a password for the current running image or preventing overwriting according to the situation visually recognized by the passenger.

Next, the case where "recording start" is "automatic" and "manual" will be described by taking the case where the event is "quick approach of another vehicle" as an example. When the vehicle sensor 3 detects that the distance between the vehicle 11 and another vehicle approaching the vehicle 11 is equal to or less than a predetermined distance, the access control unit 4b automatically performs "recording start". That is, the drive recorder 1 starts recording by triggering an event detected by the vehicle sensor 3.

Then, when the "recording start" is "automatic", the access control unit 4b sets "PW presence / absence" to "none", that is, releases the password for the recorded travel information 5b.

Further, when the passenger boarding the vehicle 11 determines that another vehicle approaching the vehicle 11 is dangerous and performs a predetermined manual operation on the drive recorder 1, the access control unit 4b "starts recording". "Manually".

Then, when the "recording start" is "manual", the access control unit 4b selects "PW presence / absence" by "selection", that is, whether to give or cancel the password to the traveling image to the passenger. Let me choose.

The access control unit 4b is, for example, separately mounted on the vehicle 11, and the approaching object may be another vehicle, a pedestrian, a flying object, or the like, depending on the detection result of the detection device that detects the object approaching the vehicle 11. It is possible to determine whether it is a moving object or an object such as a falling object on the road. Then, according to the determination result, the access control unit 4b determines an event such as "rapid approach of another vehicle", "rapid approach of a pedestrian", or "falling object / flying object".

By the way, for example, when the vehicle 11 is a rental car or a company car, the access control unit 4b manages the traveling information 5b on the company side that owns the vehicle 11 if the access restriction that only the certifier can access is set. May be difficult.

Therefore, when the certifier is an administrator, the access control unit 4b grants the certifier (administrator) access rights according to the administrator authority for all of the running images. The administrator authority is the authority to execute a privileged function on such a running image.

Here, the administrator authority given to the administrator by the access control unit 4b will be described with reference to FIGS. 8A to 8C. 8A to 8C are diagrams (No. 1) to (No. 3) for explaining the administrator authority.

Note that the administrator authority shown in FIGS. 8A to 8C is an example, and is not limited thereto. Further, the certifiers A and B shown in FIGS. 8A to 8C are, for example, passengers A and B in FIG. 5, and the certifier C is, for example, a viewer C in FIG.

Further, as a premise of the explanation of FIGS. 8A to 8C, the certifier A of the identification information 5a shown in FIG. 4 is an administrator, the certifier B is a quasi-administrator, and the certifier C is any of them. Not applicable. The quasi-administrator has, for example, administrator authority lower than the administrator A and higher than the certifier C.

As shown in FIG. 8A, the access control unit 4b grants the certifier A, who is the administrator, an access right to view the traveling information 5b of each of the certifier A, the certifier B, and the certifier C. To do. Further, the access control unit 4b grants the certifier B, who is the quasi-administrator, an access right so that the traveling information 5b of the certifier B and the certifier C can be viewed.

Further, as shown in FIG. 8B, the access control unit 4b gives the certifier A, who is the administrator, an access right that allows the driving information 5b of the certifier A, the certifier B, and the certifier C to be deleted. Give. The authority to delete the running image is preferably given only to the administrator from the viewpoint of preventing unauthorized information manipulation.

Further, as shown in FIG. 8C, the access control unit 4b sends the traveling information 5b of the certifier A, the certifier B, and the certifier C to another storage medium or the like for the certifier A who is the administrator. Grant transferable access. Further, the access control unit 4b grants the certifier B and the certifier C an access right capable of transferring only the respective driving information 5b.

By setting the administrator authority as shown in FIGS. 8A to 8C, the certifier A who is an administrator can easily manage the traveling information 5b.

<Memory unit 5>
Returning to the description of FIG. 3, the storage unit 5 will be described subsequently. The storage unit 5 is a portable storage medium such as an SD card or a USB memory. Alternatively, the storage unit 5 may be, for example, a semiconductor memory element such as a RAM (Random Access Memory) or a flash memory, or a storage medium such as an HDD or an optical disk. The storage unit 5 stores the above-mentioned identification information 5a, travel information 5b, and event information 5c.

<Display device 10>
The display device 10 reads out the travel information 5b stored in the storage unit 5 and displays it on a display unit (not shown) such as the above-mentioned display. When the viewer browses the traveling information 5b, the display device 10 displays an image requesting the viewer for a password on the display unit.

Further, the display device 10 determines whether or not the password input by the viewer matches the password given to the travel information 5b, and if the passwords match, the designated travel image is displayed.

Next, the processing procedure of the recording process executed by the drive recorder 1 according to the embodiment will be described with reference to FIG. FIG. 9 is a flowchart showing a processing procedure of recording processing executed by the drive recorder 1 according to the embodiment. During the operation of the drive recorder 1, the processing procedure of FIG. 9 is repeated at a predetermined cycle.

As shown in FIG. 9, the authentication unit 4a performs personal authentication of the passenger based on the ID and password transmitted from the portable device P and the ID and password included in the identification information 5a stored in the storage unit 5. (Step S101). The personal authentication in step S101 may be performed only once immediately after the drive recorder 1 is started. Subsequently, the imaging unit 2 images the outside of the vehicle 11 (step S102).

Subsequently, the access control unit 4b determines whether or not an event that satisfies at least a predetermined condition indicating the degree of urgency has occurred (step S103). In this determination process, when it is determined that such an event has not occurred (step S103, No), the access control unit 4b sets an access restriction for restricting access from other than the passenger in the travel information 5b (step S105). ), End the process.

On the other hand, in the determination process of step S103, when the access control unit 4b determines that such an event has occurred (steps S103, Yes), the access restriction given to the travel information 5b is released (step S104), and the process ends. To do.

The drive recorder 1 according to the embodiment can be realized by a computer 200 having a configuration shown as an example in FIG. FIG. 10 is a hardware configuration diagram showing an example of a computer that realizes the function of the drive recorder 1.

The computer 200 includes a CPU (Central Processing Unit) 210, a ROM (Read Only Memory) 220, a RAM (Random Access Memory) 230, and an HDD (Hard Disk Drive) 240. The computer 200 also includes a media interface (I / F) 250, a communication interface (I / F) 260, and an input / output interface (I / F) 270.

The computer 200 may include an SSD (Solid State Drive), and the SSD may perform some or all of the functions of the HDD 240. Further, an SSD may be provided instead of the HDD 240.

The CPU 210 operates based on a program stored in at least one of the ROM 220 and the HDD 240, and controls each part. The ROM 220 stores a boot program executed by the CPU 210 when the computer 200 is started, a program that depends on the hardware of the computer 200, and the like. The HDD 240 stores a program executed by the CPU 210, data used by the program, and the like.

The media I / F 250 reads a program or data stored in the storage medium 280 and provides the program or data to the CPU 210 via the RAM 230. The CPU 210 loads the program from the storage medium 280 onto the RAM 230 via the media I / F 250, and executes the loaded program. Alternatively, the CPU 210 executes the program using such data. The storage medium 280 is, for example, an optical magnetic recording medium such as a DVD (Digital Versatile Disc), an SD card, a USB memory, or the like.

The communication I / F 260 receives data from another device via the network 290 and sends it to the CPU 210, and transmits the data generated by the CPU 210 to the other device via the network 290. Alternatively, the communication I / F 260 receives a program from another device via the network 290 and sends it to the CPU 210, and the CPU 210 executes the program.

The CPU 210 controls a display unit such as a display and an input unit such as a keyboard, a mouse, and a button via an input / output I / F 270. The CPU 210 acquires data from the input unit via the input / output I / F 270. Further, the CPU 210 outputs the generated data to the display device 10 via the input / output I / F270.

For example, when the computer 200 functions as the drive recorder 1, the CPU 210 of the computer 200 realizes the functions of the authentication unit 4a and the access control unit 4b by executing the program loaded on the RAM 230.

The CPU 210 of the computer 200 reads, for example, these programs from the storage medium 280 and executes them, but as another example, these programs may be acquired from another device via the network 290. In addition, the HDD 240 can store the identification information 5a, the traveling information 5b, and the event information 5c stored in the storage unit 5.

As described above, the drive recorder 1 according to the embodiment includes an imaging unit 2 and an access control unit 4b. The imaging unit 2 images the outside of the vehicle 11. The access control unit 4b sets an access restriction that restricts access from a vehicle 11 other than the passengers of the vehicle 11 to the traveling image of the vehicle 11 that is imaged by the imaging unit 2 and stored in the storage unit 5. Further, the access control unit 4b releases the access restriction when the event generated with respect to the vehicle 11 satisfies at least a predetermined condition indicating a high degree of urgency.

Therefore, according to the drive recorder 1 according to the embodiment, the driving image with high urgency can be viewed by non-passengers while protecting the personal information.

Further, in the above-described embodiment, an example is shown in which traveling information 5b including a traveling image in which access restrictions are set is recorded on a portable storage medium M (for example, an SD card) that can be attached to and detached from the drive recorder 1. , Not limited to this.

For example, when the storage medium M is a server device in cloud computing, the drive recorder 1 further includes a communication unit capable of communicating with the server device. The access control unit 4b sets or cancels the access restriction that restricts access from other than the passengers of the vehicle 11 to the traveling image of the vehicle 11, and stores it in the storage unit of the server device via the communication unit.

Then, the display device 10 further includes a communication unit capable of communicating with the server device, acquires the traveling information 5b via the communication unit, and displays it on the display unit. As a result, in the display system 100, the passenger can eliminate complicated work such as reading the travel information 5b, and further, the space of the storage device for storing the travel information 5b can be eliminated.

Further effects and variations can be easily derived by those skilled in the art. For this reason, the broader aspects of the invention are not limited to the particular details and representative embodiments expressed and described as described above. Therefore, various modifications can be made without departing from the spirit or scope of the general concept of the invention as defined by the appended claims and their equivalents.
