A-4. In-vehicle camera operation:
FIG. 7 is a flowchart for explaining an operation flow of the in-vehicle camera. Here, the flow of operation of the front camera 100 will be described as an example of the in-vehicle camera. The operation of the rear camera 200 is the same as that of the front camera 100. The front camera 100 is activated when the driver turns on the ACC power of the vehicle 20 (steps S101 and S102). After activation, the camera control unit 130 of the front camera 100 controls the wireless communication unit 120 to detect the terminal device 300 that is a connection destination (step S103). As a detection method of the terminal device 300, a known detection method can be employed. For example, the front camera 100 can detect the presence of the terminal device 300 by transmitting a beacon including its own identification information and receiving a response from the terminal device 300. The camera control unit 130 determines whether there is a response from the terminal device 300 (step S104).

  When there is no response from the terminal device 300 (step S104: NO), the camera control unit 130 continues to detect the terminal device 300 until the ACC power supply of the vehicle 20 is turned off (step S105: NO). If the ACC power supply of the vehicle 20 is turned off during detection by the terminal device 300 (step S105: YES), the front camera 100 ends the operation (step S106).

  On the other hand, when there is a response from the terminal device 300 in step S104 (step S104: YES), the camera control unit 130 performs a connection process for connecting to the terminal device 300 (step S107). Thereby, the front camera 100 and the terminal device 300 are connected by wireless communication. After connection with the terminal device 300, the camera control unit 130 controls the imaging unit 110 to capture the front of the vehicle 20 and generate front image data (step S108). In addition, the camera control unit 130 transmits the generated front image data to the terminal device 300 via the wireless communication unit 120 (step S109).

  The camera control unit 130 sequentially performs photographing, generation of front image data, and transmission of front image data until the ACC power is turned off (step S110: NO). If the ACC power is turned off during the execution of the above process (step S110: YES), the camera control unit 130 ends the operation (step S111).

A-5. Terminal device operation:
FIG. 8 is a flowchart for explaining the operation flow of the terminal device. Upon receiving the DR application activation instruction, the terminal device 300 activates the DR application (steps S201 and S202). The DR application activation instruction is, for example, that the user taps a GUI (Graphical User Interface) such as an icon displayed on the display input unit 310 with a finger or the like. Thereby, the terminal control part 370 of the terminal device 300 starts control as a drive recorder. The terminal control unit 370 performs an in-vehicle camera connection process for connecting to the in-vehicle camera (step S210). The contents of the in-vehicle camera connection process will be described later with reference to FIG. Here, it is assumed that the terminal device 300 is connected to both the front camera 100 and the rear camera 200 through the in-vehicle camera connection process.

  Subsequently, the terminal control unit 370 performs a vibration device connection process for connecting to the vibration device 500 (step S220). The contents of the vibration device connection process will be described later with reference to FIG. Here, it is assumed that the terminal device 300 is connected to the vibration device 500 through the vibration device connection process. After the two connection processes, the terminal control unit 370 receives image data from the in-vehicle cameras (the front camera 100 and the rear camera 200) via the wireless communication unit 350, and writes the received image data in the storage unit 340. (Step S231). Specifically, the terminal control unit 370 sequentially acquires the front image data received from the front camera 100 and the rear image data received from the rear camera 200 in time series, and writes them in the storage unit 340. When the storage area for the drive recorder in the storage unit 340 becomes full due to the writing of the image data, the terminal control unit 370 rewrites the oldest image data therein to the latest image data. Therefore, the storage unit 340 stores image data written in a time series in a time period from when the image data was last written until a predetermined time (for example, 30 seconds). In other words, the storage unit 340 records a front image and a rear image of the vehicle 20 from the present to a predetermined time (for example, 30 seconds) before. The terminal control unit 370 continues to receive image data from the in-vehicle camera and write to the storage unit 340 until detecting a DR application termination instruction from the user.

  The terminal control unit 370 starts display image switching control in parallel with reception and writing of image data (step S232). The display image switching control is a control for switching the display image displayed in the display area of the display input unit 310 according to the state of the vehicle (forward or reverse), and the details will be described later with reference to FIGS. To do. Further, the terminal control unit 370 detects whether an event has occurred in the vehicle 20 in parallel with the reception and writing of the image data (step S240). The event here refers to an event that should hold an image as a drive recorder, such as a collision between vehicles, a collision with a workpiece, or a vehicle rollover. The terminal control unit 370 detects whether an event has occurred in the vehicle 20 based on the detection value DVa output from the acceleration sensor 320 and the detection value DVs output from the sound sensor 330. Specifically, in the terminal device 300, a threshold value Th1 corresponding to the detection value DVa when a strong impact at the time of occurrence of an event is detected is registered in advance, and the terminal control unit 370 is output from the acceleration sensor 320. The occurrence of an event is detected when the detection value DVa becomes equal to or greater than the threshold value Th1. The terminal device 300 is pre-registered with a threshold Th2 corresponding to the detection value DVs when the sound volume generated when the airbag is activated, and the terminal control unit 370 is output from the sound sensor 330. The occurrence of an event is also detected when the detection value DVs becomes equal to or greater than the threshold value Th2.

  When the terminal control unit 370 detects the occurrence of an event (step S240: YES), the terminal control unit 370 performs an image data holding process (step S241). The image data holding process is a process for holding the front video and the rear video of the vehicle 20 in a specific period set in advance. The specific period is a period that can be arbitrarily set in relation to the time point at which the occurrence of an event is detected (event detection time point). For example, a period including 5 seconds before and 5 seconds after the event detection time, A period including only 15 seconds before the time can be exemplified. Here, it is assumed that the storage unit 340 can record the front video and the rear video for 30 seconds each, and the specific period includes a period including 15 seconds before the event detection time point and 15 seconds after the event detection time point. explain. In this case, the storage unit 340 at the time of event detection records a front video and a rear video for 30 seconds before the event detection time. Therefore, the terminal control unit 370 continues writing the received front image data and rear image data to the storage unit 340 for 15 seconds after detecting the event, and writes these image data to the storage unit 340 after 15 seconds. To stop. Thus, the storage unit 340 stores the image data written between 15 seconds before the event detection time and 15 seconds after the event detection in a time series. That is, the storage unit 340 is in a state where a front video and a rear video for 15 seconds before and after the occurrence of the event are recorded. Note that the terminal control unit 370 may be configured to perform image data holding processing only on one of the front video and the rear video. For example, when the terminal control unit 370 determines that a collision of the vehicle 20 has occurred on the front side of the vehicle 20 based on a change in the detection value DVa output from the acceleration sensor 320, the image data only for the front image. It is good also as a structure which performs a holding process.

  After the image data holding process, the terminal control unit 370 transmits the image data written in the storage unit 340 to the registered contact via the mobile communication unit 360 (step S242). The image data transmitted to the registered contact is image data representing a front video and a rear video for 15 seconds before and after the occurrence of the event. The image data to be transmitted may be image data representing a video of a part of the above-described period, or may be image data representing one of the front video and the rear video. For example, when the image data holding process is performed on only one of the front video and the rear video, the terminal control unit 370 transmits only one video (for example, the front video) that has been subjected to the image data holding process. It is good also as a structure. Note that the terminal control unit 370 may appropriately convert the format of the image data at the time of transmission. For example, the MJPEG format may be converted into a moving image format such as AVI (Audio Video Interleave) or MP4. The registered contact is a contact registered in advance by the user, and can be exemplified by an insurance company, a home, a company, and the like. In this manner, by transmitting the image data written in the storage unit 340 to the registered contact information, for example, even if a fire or the like occurs in the vehicle 20 after the event occurs, the image data is lost due to the burnout of the terminal device 300. Can be prevented.

  In addition, as shown to step S240 and step S243, the terminal control part 370 detects whether the event has generate | occur | produced in the vehicle 20 until the completion | finish instruction | indication of DR application is received. If the terminal control unit 370 receives a DR application termination instruction while detecting whether or not an event has occurred (step S243: YES), the terminal control unit 370 terminates the DR application (step S244).

  The in-vehicle camera connection process in step S210 will be described with reference to FIG. FIG. 9 is a flowchart for explaining the flow of the in-vehicle camera connection process. The terminal control unit 370 determines whether there is an in-vehicle camera (step S211). Whether or not an in-vehicle camera exists can be determined, for example, by whether or not a beacon transmitted from the front camera 100 and the rear camera 200 is detected.

  When there is no vehicle-mounted camera (step S211: NO), that is, when the beacon from the front camera 100 or the rear camera 200 cannot be received, the terminal control unit 370 detects the vehicle-mounted camera until a predetermined time elapses. (Step S212: NO), and when a predetermined time has elapsed (step S212: YES), the DR application is terminated (step S213). Note that the terminal control unit 370 determines that no in-vehicle camera is present even when a beacon is received from an external device other than the front camera 100 and the rear camera 200. In the terminal device 300, the identification information of the front camera 100 and the rear camera 200 is registered in advance, and transmission is performed by comparing the identification information of the transmission source included in the received beacon with the registered identification information. It is determined whether or not the original is the front camera 100 or the rear camera 200.

  In step S211, when a vehicle-mounted camera exists, that is, when a beacon is received from the front camera 100 or the rear camera 200, the terminal control unit 370 performs a connection process for connecting to the vehicle-mounted camera that has received the beacon (step S214).

  The vibration device connection process in step S220 will be described with reference to FIG. FIG. 10 is a flowchart for explaining the flow of the vibration device connection processing. The terminal control unit 370 determines whether or not the vibration device 500 is present (step S221). Whether or not the vibration device 500 exists can be determined by whether or not a beacon transmitted from the vibration device 500 is detected. When the vehicle-mounted camera does not exist (step S211: NO), that is, when the beacon from the vibration device 500 cannot be received, the terminal control unit 370 continues to detect the vibration device 500 until a predetermined time elapses. (Step S222: NO) When a predetermined time has elapsed (Step S222: YES), the connection process is terminated (Step S222). In step S221, when the vibration device 500 exists, that is, when a beacon is received from the vibration device 500, the terminal control unit 370 performs a connection process for connecting to the vibration device 500 (step S223). Thereafter, the terminal control unit 370 starts operation monitoring control (step S224). Driving monitoring control refers to the positional relationship between a specific object (front vehicle, signal, lane, person, etc.) outside the vehicle 20 and the vehicle 20, and the driver's response to the specific object (deceleration of the vehicle with respect to the signal red). To the driver according to the presence / absence of slow / stop signs, etc., the running state of the vehicle 20 (overspeed, meandering, etc.), the driver's own state (sleeping, looking aside, etc.), time, weather, current position, etc. Control to call attention.

  FIG. 11 is a flowchart for explaining the flow of operation monitoring control. When the terminal control unit 370 starts the operation monitoring control in step S224 (FIG. 10), the terminal control unit 370 first detects a state requiring attention (step S301). The attention required state here refers to a state or situation where attention should be given to a driving driver, and the following states can be exemplified. First, when the inter-vehicle distance between the vehicle 20 and the preceding vehicle becomes a predetermined value or less, or when the vehicle 20 straddles a lane, the positional relationship between the specific object outside the vehicle 20 and the vehicle 20 is normal. Different states are included. Also, if the vehicle 20 has not started decelerating when the signal is switched to red, if the vehicle 20 has not started slowing when there is a slowing sign, it is heading in that direction when there is a one-way sign This includes situations where there is no driver response required for a particular object, such as when there is no such object. In addition, when the vehicle 20 exceeds the legal speed, when the vehicle 20 is meandering, a state where the traveling state of the vehicle 20 is different from the normal state is included. In addition, the driver's own state is different from the normal state, such as the driver falling asleep or driving aside. In addition, the same time as when the driver has fallen asleep in the past, the place where the signal was ignored in the past, the weather when the distance between the vehicle and the vehicle ahead was less than the predetermined value in the past, etc. The state of becoming the same, the state of the same weather, and the state of reaching the same place are included. Hereinafter, a configuration will be described in which the terminal controller 370 detects a state requiring attention based on whether or not the distance between the vehicle 20 and the preceding vehicle is equal to or less than a predetermined value.

  FIG. 12 is an explanatory diagram for explaining a method for detecting a state requiring attention. FIG. 12A illustrates a front image IMf when the distance between the vehicle 20 and the preceding vehicle is greater than a predetermined value. FIG. 12B illustrates a front image IMf when the distance between the vehicle 20 and the preceding vehicle is equal to or less than a predetermined value. The terminal control unit 370 detects the forward vehicle included in the forward image IMf by pattern matching. The pattern image used at this time is stored in advance in the storage unit 340 or the like. When the terminal control unit 370 detects the image area ADp representing the preceding vehicle by pattern matching, the terminal control unit 370 calculates a ratio (ratio) of the image area ADp occupying the entire forward image IMf, and based on the ratio, the distance between the vehicle 20 and the preceding vehicle is calculated. Estimate distance. That is, since the ratio of the image area ADp increases as the inter-vehicle distance between the vehicle 20 and the preceding vehicle decreases, the terminal control unit 370 determines whether the inter-vehicle distance is equal to or less than a predetermined value depending on whether the calculated ratio is greater than a threshold value. It can be determined whether or not.

  The terminal control unit 370 may perform pattern matching using a plurality of pattern images having different vehicle types such as a large car and a small car. In this case, in the pattern image having the highest correlation value calculated by pattern matching with each pattern image, the ratio (ratio) of the image region ADp in the entire front image IMf may be calculated. The threshold for this ratio may be configured to be different for each pattern image. That is, in the pattern image of the large vehicle, the inter-vehicle distance may be sufficient even if the ratio of the image area ADp occupying the entire front image IMf is large. Therefore, the corresponding threshold value is higher than the threshold value corresponding to the pattern image of the small vehicle. Is set to be larger. In addition, it is not limited to the calculation method of the distance between vehicles with a preceding vehicle, or the above. For example, if the drive recorder system 10 includes a plurality of front cameras, the inter-vehicle distance from the preceding vehicle can be calculated by triangulation or the like.

  The above-described method for detecting the attention required state is an example, and the method for detecting the attention required state is not limited to the above-described method. For example, the terminal control unit 370 detects a lane included in the front image IMf, and when the relative position of the image representing the detected lane with respect to the entire front image IMf satisfies a predetermined condition, the terminal control unit 370 sets the attention required state. It may be detected. In addition, the terminal control unit 370 may detect passersby, signals, license plates, road signs, and the like included in the front image IMf, and detect a state requiring attention from the position and size of these images.

  When the terminal control unit 370 detects a state requiring attention (FIG. 11, step S301: YES), the terminal control unit 370 starts an alarm and records the situation (step S302). Specifically, the terminal control unit 370 makes a first notification to the vibration device 500 in order to operate the vibration device 500. The vibration device 500 that has received the first notification drives the vibration motor 510 to vibrate the handle 670 (FIG. 2). Thereby, it is possible to alert the driver who is driving. The terminal control unit 370 may display the caution content on the display input unit 310 of the terminal device 300 in accordance with the vibration of the handle 670. Further, the caution content may be output by voice from a speaker (not shown).

  The terminal control unit 370 records the situation when the attention required state is detected. Specifically, the terminal control unit 370 records, in the storage unit 340, situation information such as a forward image, time, and acceleration of the vehicle 20 when the attention required state is detected. By doing so, the driving record of the driver of the vehicle 20 can be easily left. Moreover, the alarm can be started at the same time as the time when the attention required state is detected in the past. By starting an alarm in a time zone where a caution requiring state is likely to occur, the occurrence of a caution requiring state can be prevented. If the terminal device 300 includes, for example, a GPS (Global Positioning System) receiver and can acquire current position information, or if weather information can be acquired through an Internet line, a state requiring attention is detected. Such information may also be recorded as situation information. By doing so, the alarm can be started when the vehicle 20 reaches the same position as the position where the attention required state has been detected in the past, or when the weather is the same as the weather where the attention required state has been detected in the past. . By starting an alarm in a weather or a position where a caution requiring state is likely to occur, the occurrence of a caution requiring state can be prevented.

  After the alarm, the terminal control unit 370 detects a driver response to the alarm (step S303). The driver response can be detected by any method. For example, the terminal control unit 370 responds to the driver when the display input unit 310 detects a tap, when the sound sensor 330 detects a predetermined sound, when the acceleration sensor 320 detects negative acceleration due to braking, or the like. To detect.

  If there is no response from the driver (step S303: NO), the terminal control unit 370 increases the intensity of the alarm (step S304). Specifically, the terminal control unit 370 performs the second notification to the vibration device 500 when there is no response from the driver within a predetermined period after the first notification to the vibration device 500. . The vibration device 500 that has received the second notification increases the drive amount of the vibration motor 510 and increases the vibration intensity of the handle 670. At this time, the terminal control unit 370 may start outputting the sound from the speaker or may increase the volume. Further, the terminal control unit 370 may perform status recording. By doing in this way, an alarm can be started in the time, the weather, or the place where there was no response to the alarm in the past. By starting the alarm at a time, weather, or place where there is no response to the alarm, it is possible to prevent the alert state requiring attention. When the terminal control unit 370 detects a driver response (step S303: YES), the terminal control unit 370 stops the alarm (step S305).

  Display image switching control will be described with reference to FIGS. FIG. 13 is a flowchart for explaining the flow of display image switching control. FIG. 14 is an explanatory diagram illustrating a display image displayed in the display area of the terminal device. When the display image switching control is started in step S232 (FIG. 8), the terminal control unit 370 first arranges the front image IMf and the rear image IMr in the display area of the display input unit 310 in parallel as shown in FIG. Are displayed (parallel two-screen display) (step S401). When the terminal control unit 370 detects the backward movement of the vehicle 20 (step S402: YES), as shown in FIG. 14B, the terminal control unit 370 displays the rear image IMr in the entire display area of the display input unit 310 (one-screen display). (Step S403). Thereby, the terminal device 300 can be used as a back monitor. Note that the terminal control unit 370 determines whether or not the vehicle 20 has started moving backward based on the detection value DVa output from the acceleration sensor 320. Specifically, the terminal device 300 is registered in advance with the characteristics of changes in the x-axis, y-axis, and z-axis directions of acceleration obtained during backward travel in the terminal device 300 attached to the card case 610. Thus, the terminal control unit 370 detects the reverse of the vehicle 20 when the change in the detection value DVa output from the acceleration sensor 320 matches the characteristic. Note that the terminal control unit 370 may be configured to switch the display screen even when receiving an input to the display input unit 310 by the user.

  According to the drive recorder system of the first embodiment described above, since the storage unit 340 of the terminal device 300 previously owned by the user is used as the recording device for recording the front video and the rear video, the drive recorder The cost for constructing can be reduced. That is, when configuring the drive recorder as the system of the present embodiment, it is not necessary to purchase a separate recording unit for recording the front video and the rear video, so that the cost of the drive recorder can be reduced accordingly. it can. In addition, according to the drive recorder system of the first embodiment, since the occurrence of an event is detected using the acceleration sensor 320 and the sound sensor 330 provided in the terminal device 300, compared to the case where these sensors are purchased separately. The cost of the drive recorder can be reduced.

  FIG. 15 is an explanatory diagram comparing a conventional terminal mounting member and a terminal mounting member of the present embodiment. 400 A of terminal attachment members of the prior art are provided with the terminal fixing | fixed part 410a, the base part 420a, and the leg part 430a. The terminal fixing part 410a fixes the terminal device 300 to the terminal attachment member 400A. The base part 420a fixes the terminal attachment member 400A to the upper surface part 602 of the instrument panel 600 with a suction cup or an adhesive surface. The leg part 430a is disposed between the terminal fixing part 410a and the base part 420a, and supports the terminal fixing part 410a on the upper part of the base part 420a. Since the terminal attachment member 400A of the conventional example needs to photograph the front of the vehicle 20 by the imaging unit 380 (FIG. 5) built in the terminal device 300, the terminal attachment member 400A is attached to the upper surface portion 602 of the instrument panel 600. It is held above the upper surface portion 602 of 600. However, in the case of such a configuration, when an event such as a collision of the vehicle 20 occurs, the terminal mounting member 400A may be detached from the instrument panel 600 due to the inertial force Fi. When the terminal mounting member 400A is detached from the instrument panel 600, the terminal device 300 collides with the windshield and breaks, and the negative acceleration due to the occurrence of the event is not transmitted to the terminal device 300. There was a problem that could not be detected.

  On the other hand, in the terminal attachment member 400 of the present embodiment, a part of the terminal device 300 (a part included in the range of the width Wt) is interposed between the side surface part 601 of the instrument panel 600 and the traveling direction D of the vehicle 20 via the terminal fixing part 440fr. Therefore, even if an event occurs, the movement of the terminal device 300 by the inertial force Fi can be regulated by the reaction force Fr from the side surface portion 601 of the instrument panel 600. Moreover, according to the terminal attachment member 400 of this embodiment, since the terminal device 300 can be attached to the interior member at a position where it is difficult to be exposed to direct sunlight, deterioration of the terminal device 300 due to direct sunlight can be suppressed.

N. Fourteenth embodiment:
FIG. 28 is an explanatory diagram for explaining a method of detecting a state requiring attention using an indoor image including a driver's face. FIG. 28A illustrates a schematic configuration of the drive recorder system of the fourteenth embodiment. FIG. 28B illustrates an indoor image IMi including the driver's face. The drive recorder system 11 according to the fourteenth embodiment detects a state requiring attention using the indoor image IMi in the operation monitoring control. The drive recorder system 11 of the fourteenth embodiment is different from the drive recorder system 10 of the first embodiment in that the rear camera 200 is not provided and the indoor camera 101 is provided. Other points are the same as in the drive recorder system 10 of the first embodiment. As shown in FIG. 28A, the drive recorder system 11 includes a front camera 100, an indoor camera 101, a terminal device 300, a terminal mounting member 400, and a vibration device 500. The indoor camera 101 is mounted above the windshield of the vehicle 20 and is oriented so as to photograph the driver's face. The indoor camera 101 transmits image data representing the captured indoor image IMi to the terminal device 300.

  The terminal control unit 370 of the terminal device 300 detects the face of the driver included in the room image IMi by pattern matching. When the terminal control unit 370 detects the image area ADf representing the driver's face by pattern matching, the terminal control unit 370 determines whether the area ADi corresponding to the eye of the image area ADf is an image with closed eyes. It is possible to determine whether or not the image is an image with closed eyes by any method. For example, it is possible to calculate a correlation value by pattern matching with a pattern image in a state where the eyes are open or in a state where the eyes are closed, and determine whether the correlation value exceeds a threshold value. The terminal control unit 370 detects the driver's sleep when the driver's image with his eyes closed is included in the room image IMi acquired for a predetermined period (for example, 5 seconds). That is, a state requiring attention is detected. The terminal control unit 370 can detect by pattern matching by detecting the eye position and the face direction of the driver's face driver included in the room image IMi. Moreover, it is good also as a structure which detects a driver's looking aside by detecting the position of eyes, nose, and a mouth.

O. Variations:
The present invention is not limited to the above-described embodiments and embodiments, and can be implemented in various modes without departing from the gist thereof. For example, the following modifications are possible.

O-1. Modification 1:
In the drive monitoring system 10, in the driving monitoring control, the position and size of specific objects such as signals and road signs included in the front image IMf, and after these specific objects appear in the front image IMf The alert state requiring attention may be detected based on the presence or absence of a driver's response. For example, when the terminal control unit 370 detects that the front image IMf contains a red signal, the acceleration sensor 320 does not detect the negative acceleration due to the brake within a predetermined period (for example, 5 seconds). You may detect that it is a state requiring attention. Further, for example, when the terminal control unit 370 detects that the one-way road sign is included in the front image IMf, the acceleration sensor 320 does not detect the inertial force due to the turning of the vehicle 20 within a predetermined period. It may be detected that it is in a state requiring attention.

  Further, the drive recorder system 10 may detect the attention required state based on the detection value DVa output from the acceleration sensor 320 in the driving monitoring control. For example, when the acceleration sensor 320 detects an acceleration equal to or higher than a predetermined value, the terminal control unit 370 may detect that the vehicle 20 is in an alert state requiring attention that the vehicle 20 has exceeded the speed. In addition, when the acceleration sensor 320 detects positive acceleration and negative acceleration alternately, it may be detected that the vehicle 20 is in a state of calling attention because it is staggered.

  Further, the drive recorder system 10 may detect a state requiring attention based on the situation record stored in the storage unit 340 in the operation monitoring control. For example, when the acceleration sensor 320 detects an acceleration equal to or higher than a predetermined value, the terminal control unit 370 may detect that the vehicle 20 is in an alert state requiring attention that the vehicle 20 has exceeded the speed. In addition, when the acceleration sensor 320 detects positive acceleration and negative acceleration alternately, it may be detected that the vehicle 20 is in a state of calling attention because it is staggered.

O-2. Modification 2:
Although the drive recorder system 10 has been described as a configuration that alerts the driver by the vibration of the handle 670, the method of alerting the driver can be performed by any method. For example, the display input unit 310 of the terminal device 300 and the light source unit (not shown) of the vibration device 500 may flash to alert the driver visually. In the case where the terminal device 300 visually or audibly alerts the driver, the drive recorder system 10 may not include the vibration device 500. The vibration device 500 may be attached to a place other than the handle 670 such as the seat 900.

O-3. Modification 3:
The terminal device 300 of the drive recorder system 10 may include a GPS (Global Positioning System) receiver. By doing so, the position information can be used as the situation information. Further, a navigation image can be displayed on the display input unit 310. Further, when the occurrence of an event is detected, the position information of the vehicle 20 can be transmitted to the registered contact information together with the image data.

O-4. Modification 4:
The in-vehicle cameras 100 and 200, the terminal device 300, and the vibration device 500 may be connected to each other by a wired LAN such as Ethernet (registered trademark) or a wired line such as USB. The terminal device 300 may not include any one of the acceleration sensor 320 and the sound sensor 330. The drive recorder system 10 may not include the rear camera 200. Further, the drive recorder system 10 may be configured not to include the mobile communication unit 360 and to transmit image data to the registered contact information. Further, the back monitor function may not be provided.

O-5. Modification 5:
In the first embodiment, the DR application is described as being activated when the user taps an icon. However, the DR application may be automatically activated when the terminal device 300 is in the vehicle 20. That is, the terminal device 300 may be configured to activate the DR application even when there is no instruction from the user when detecting that the terminal device 300 is located in the vehicle 20. By doing so, it is possible to prevent the user from forgetting to start the DR application.
