Description

The present invention relates to, for example, devices and programs.

A drive recorder that stores vehicle status information (front image, vehicle speed, sudden acceleration / deceleration, etc.) before and after a car accident will provide useful information for verification in the event of a car collision. In particular, it is widely used in transportation vehicles such as trucks and commercial vehicles such as taxis and buses, and is also being installed in general vehicles.

This drive recorder can store forward images for a certain period before and after an accident, sudden braking, etc., and driving data showing the driver's driving operation (brake operation, turn signal operation, driving route, etc.). It is composed. To briefly explain the configuration for storing video data, a CMOS camera or the like constantly captures the image of the vehicle and its surroundings from the driver's viewpoint (viewpoint), and the captured video is stored in a temporary storage memory such as a ring buffer. Remember in. The video stored in the temporary storage memory is sequentially updated to the latest one, and the past video data is retained for the set time. On the other hand, the drive recorder is equipped with a sensor that detects an accident such as an acceleration sensor or an impact generated during sudden braking or sudden steering, and when the output value of the sensor exceeds the threshold value, from the time when the threshold value is exceeded (impact detection). The video of the previous fixed period is read from the temporary storage memory and stored in the non-volatile memory (SD card, etc.), and after the time when the threshold is exceeded, the video of the CCD camera, etc. captured after that is directly or temporarily stored in the non-volatile memory. By storing it via a storage memory, it has a function of storing images for a predetermined time before and after the impact and the traveling data and the like in a non-volatile memory (SD card or the like).

Then, when an accident occurs, it is possible to clearly prove the correctness of the driver based on the vehicle status information (video, etc.) of the own vehicle stored in the non-volatile memory. This type of drive recorder is disclosed in, for example, Patent Document 1 and the like.

However, the conventional system has a problem that it is difficult to know whether the recording means is in a state to be replaced, and whether the image recorded on the recording means is properly reproduced by the user operating the play button or the like of the device. If you do not check regularly, there is a problem that you cannot know whether the video is properly recorded in the recording means, and there is a problem that it takes time and effort to operate the play button one by one. As a result, various problems such as the fact that the video is not properly recorded in the recording means only when a vehicle accident or the like actually occurs without the user and it is necessary to reproduce the video. was there.
Therefore, an object of the present invention is to provide an apparatus, a program, or the like having better characteristics than the conventional ones.

The object of the present invention is not limited to this, and the intention is to acquire the right of the configuration for the purpose of obtaining the effect of the configuration disclosed in the present specification, drawings, etc. by divisional application, amendment, or the like. For example, the present specification discloses a problem in which a part described as "-can" or "-is possible" in the present specification is replaced with "-is a problem". The issues are described as independent, and we intend to independently acquire the rights to the structure for solving each issue by divisional application, amendment, etc. Even if the subject matter is implicitly grasped from the description in the specification, the applicant intends to make a part of the structure described in the specification amended or to make the claims in the divisional application. It also discloses a structure that solves the problems by combining these independent problems, and has the intention to acquire the rights.

(1) A device having a function of inputting an image from a camera installed in a vehicle and recording it in a recording means.
It has a function to detect the user's vehicle operation to switch the vehicle from the runnable state to the non-runnable state.

A device having an automatic reproduction function for reproducing a predetermined range of recorded images recorded in the recording means in response to detecting a user's vehicle operation for switching the vehicle from a travelable state to a non-travelable state. It is good to say.

By doing so, the user simply operates the vehicle to switch the vehicle from the runnable state to the non-runnable state, and automatically obtains a predetermined range of images from the recorded cameras recorded in the recording means. Can be regenerated. Therefore, it is easy to understand whether the video is properly recorded in the recording means without the user operating the play button or the like of the device to confirm whether the video recorded in the recording means is properly played. Further, it is not necessary for the user to operate the play button or the like of the device to periodically check whether the video recorded on the recording means is properly played back. Moreover, the user does not have to operate the play button. As a result, it is possible to reduce the possibility that the image is not properly recorded in the recording means only when a vehicle accident or the like actually occurs and it becomes necessary to reproduce the image.

The detection of the user's vehicle operation that switches the vehicle from the runnable state to the non-runnable state outputs, for example, that the push start switch of the vehicle is turned off, the key of the vehicle is operated, and the engine or the like is turned off. It is advisable to input and detect by branching the signal line of the vehicle.

This device may be a device that is retrofitted to the vehicle after being shipped from the vehicle manufacturer's factory. The present device may be dispersed in a plurality of housings to have a partial configuration thereof, but it is particularly preferable to house the apparatus in one housing. Further, the display means may be accommodated in one housing. The vehicle may be a special vehicle such as a forklift, but it is particularly preferable to use a vehicle having four or more wheels.

"Installation" may be configured to be installed in the vehicle after the vehicle manufacturer ships from the factory. For example, it is fixed by sticking the housing of this device or the fixture attached to the housing to the vehicle interior with double-sided tape or the like. It is good to have a configuration that can be installed.

The camera may be, for example, at least one of a camera that captures the front of the vehicle, a camera that mainly captures an area other than the front, and a camera that captures the driver. The number of cameras may be one, but it is particularly preferable to provide a plurality of cameras so that the images taken by the plurality of cameras can be recorded in synchronization with each other so as to be playable. For example, each video data is stored by associating the video data from the camera with the time data acquired from GPS or the like, and the video data corresponding to the time data of the same time stored in association with each video data is stored at the same time. It is good to have a configuration to reproduce.

The video in a predetermined range may be provided with a constantly recorded video, but it is particularly preferable to include a video recorded at an event. In this way, the user can automatically perform the video at the time of the event occurrence only by performing an operation of cutting off the power supply from the vehicle to the device.

The recording means may be a non-volatile memory, and in particular, a non-volatile memory having a shorter life than DRAM or the like may be used. The recording means may be a NAND flash memory in particular. The recording means may be fixed to a substrate or the like inside the housing of the apparatus, but it is particularly preferable to use a recording medium that can be attached to and detached from the apparatus. The recording means may be a card-shaped recording medium, particularly an SD card or a micro SD card.

(2) The detection of the vehicle operation of the user who switches the vehicle from the runnable state to the non-runnable state is performed based on the fact that the power supply from the vehicle to the device is cut off.
It has a function to continue operation by supplying power from the backup power supply when the power supply from the vehicle to the device is cut off.

It is preferable to use a device having an automatic reproduction function for reproducing a predetermined range of images among the recorded images recorded by the recording means in response to the interruption of the power supply from the backup power source.

By doing so, when the power supply from the vehicle to the present device is cut off, the video in a predetermined range among the recorded video recorded in the recording means is automatically reproduced in the vehicle. Therefore, the user does not need to operate the play button of the device or the like to check whether the image recorded on the recording means is played properly, and simply plays the image automatically when the power supply to the device is cut off. You can check whether the recording method is properly installed just by looking at the video.

For example, the "supply of power from the vehicle to the device" may be configured to be particularly supplied from the cigar socket of the vehicle. The device may be configured to operate while the power is supplied from the vehicle. For example, the device may be configured to receive power from a cigar socket of the vehicle and a battery different from the car battery for controlling the vehicle itself such as a mobile battery.

Further, for example, "supply of power from the vehicle to the device" is such that the electric power required for starting the vehicle itself is supplied from the car battery for supplying each part of the vehicle, and "power supply from the vehicle to the device" is received. It is advisable to connect to a signal line on the vehicle side (for example, a power line of a cigar socket) capable of determining "when the supply is cut off" and make a determination based on the signal state of the signal line.

(3) The function of stopping the recording of the image from the camera to the recording means and performing the automatic reproduction in response to the detection of the user's vehicle operation of switching the vehicle from the travelable state to the non-travelable state. You should be prepared.

By doing so, it is not necessary to record the image of the camera and play back the recorded image at the same time, the processing load and the power consumption can be reduced, and the recorded image during driving before switching to the inoperable state can be achieved. Can be automatically regenerated according to the detection of the user's vehicle operation for switching the vehicle from the runnable state to the non-runnable state.

When the configuration of (2) is provided, the function of stopping the recording of the image from the camera to the recording means and performing the automatic reproduction in response to the power supply from the vehicle to the device being cut off. It is particularly preferable to have a configuration including.

(4) A function of recording the image from the camera to the recording means in the parking recording mode for recording different from the traveling image recording mode for recording in the travelable state after the completion of the automatic reproduction. It is good to have a configuration to prepare.

By doing so, the user simply operates the vehicle to switch the vehicle from the runnable state to the non-runnable state, and automatically obtains a predetermined range of images from the recorded cameras recorded in the recording means. And after the automatic reproduction is completed, the recording in the parking recording mode can be automatically executed without any operation.

As the "parking recording mode for recording different from the traveling video recording mode", for example, it is preferable to adopt a recording method in which the parking recording mode suppresses the power consumption of the device rather than the traveling video recording mode. For example, it may be better to lower the frame rate in the parking recording mode than in the running video recording mode, or to record the video only when an impact is detected.

When the configuration of (2) is provided, even after the automatic reproduction is completed, the operation is continued by the power supply from the backup power supply, and the parking recording mode is entered so that the image from the camera can be recorded in the recording means. It is good to say.

(5) The image in the predetermined range is provided with a function of recording the image in the period of the vehicle in the travelable state immediately before the user's vehicle operation for switching the vehicle from the vehicle in the travelable state to the non-travelable state is detected.

By doing so, the user simply operates the vehicle to switch the vehicle from the runnable state to the non-runnable state, and the period of the immediately preceding runnable state of the recorded images from the camera recorded in the recording means. The video recorded in is automatically reproduced. Therefore, this time, when the user switches the vehicle to the non-driving state, the image of the driving in the latest driving unit between the time when the vehicle is switched from the runnable state to the non-running state is automatically and easily displayed. The user can confirm. Therefore, for example, it is possible to easily confirm on the spot from the driver's seat by a video while the memory of one's own driving is clear, for example, whether or not one's own driving this time was appropriate.

For example, when the configuration of (2) is provided, a predetermined period within the vehicle power supply range at the time when the power supply from the vehicle to the device is started immediately before the power supply from the vehicle to the device is cut off. It is good to have a function to make the image of.

(6) If there is no image of the target recorded in the period of the runnable state immediately before the user's vehicle operation for switching the vehicle from the runnable state to the non-runnable state is detected, the vehicle power supply range further before. It is preferable to have a function to search and play back the video recorded in.

For example, in the case of the configuration of (7) described later and the target video is an event-recorded video, the "predetermined period" is the video if there is an event record during the current driving period. If there is no event record during the travel period, it is preferable to have a function to search for the event by sequentially tracing back to the previous travel period.

For example, if you use a car to commute from your home to the office, if you start the engine at the office and turn off the engine at your home when you return home from the office today, if there is no event record as the target video in the meantime Before that, I started the engine at home and searched the range where the engine was turned off at the company during the main sunrise shift. If there is no event record in this range, it is advisable to search and play back in sequence, such as when returning home the day before, when working at sunrise the day before, and so on.

For example, when the configuration of (2) is provided, if there is no image recorded in the recording means for a predetermined period in the vehicle power supply range, the image recorded in the previous vehicle power supply range is searched for and reproduced. It is good to have a function to do.
(7) It is preferable to include an event-recorded video as the video for the predetermined period.

By doing so, the user simply operates the vehicle to switch the vehicle from the runnable state to the non-runnable state, and the event is recorded in a predetermined range of the recorded images from the camera recorded in the recording means. The video can be played back automatically.

The event recording may be configured to record, for example, when it is detected that a signal from a sensor or a switch has changed to a predetermined state. For example, the video recorded when it is determined that an event has occurred may be a video including the time when the event occurred, and in particular, a predetermined number of seconds before the event occurred (for example, 15 seconds), especially the event occurred. It is preferable to set the predetermined number of seconds (for example, 15 seconds + 20 seconds = 35 seconds) including the subsequent predetermined number of seconds (for example, 20 seconds).

The user simply operates the vehicle to switch the vehicle from the runnable state to the non-runnable state, and automatically reproduces a predetermined range of the recorded event-recorded images recorded in the recording means. Can be done.
(8) It is preferable to have a function of reproducing only a part of the recording time of the video recorded at the event without reproducing the entire range of the recording time recorded corresponding to the event.

In this way, the user can grasp the outline of the video recorded in the event in the vehicle in a short time. In particular, when the user operates the vehicle to switch the vehicle from the runnable state to the non-runnable state, the user may get off the vehicle in a relatively short time thereafter. It is possible to easily confirm in a short time until this disembarkation.

For example, when the event recording is configured to record a total of 35 seconds of video including 15 seconds before the event occurs and 20 seconds after the event occurs, as a partial range, for example, 10 seconds before the event occurs. It is advisable to reproduce a total of 15 seconds, which is 5 seconds after the event occurs. In particular, as a partial range, if the number of playback seconds before the event occurs is longer than the number of playback seconds after the event occurs, even if it is not possible to turn your eyes to the display means immediately after the start of playback, when the event occurs. It is good because it increases the possibility that you can check the image of.

As a partial range, the number of seconds of the moving image should be within 15 seconds. By doing this, you can easily upload to SNS such as Tiktok by taking a picture of the display means with a smartphone.

It would be nice to be able to set the number of seconds for a part of the video. In particular, it is preferable to have a function to store the number of seconds for each type of SNS in the device in advance and set the number of seconds to be played as a partial range by the user selecting the type of SNS.
(9) As a function of reproducing only a part of the range, it is preferable to have a function of setting a reproduction start position of the video recorded in the event.

For example, it is preferable to start the reproduction from the position after a predetermined number of seconds (for example, 5 seconds) from the beginning of the event recording. For example, it is preferable to have a function to set the number of seconds before and after the event occurrence position (for example, the trigger position) as the starting point.
(10) It is preferable to have a function of continuously reproducing a plurality of the recorded images of the event.

By doing so, the user simply operates the vehicle to switch the vehicle from the runnable state to the non-runnable state, and continuously captures the images of a plurality of event records recorded by the recording means from the recorded cameras. It can be played automatically.

The video can be automatically played back, and the user can input whether or not there is an abnormality in the video played by this automatic playback function, and the normality / abnormality of the recording means can be determined based on the input result. ..

In particular, the function of letting the user input whether or not there is an abnormality in the video played by the automatic playback function is a function of inputting an instruction indicating that the video has been viewed, in particular, when the automatically played video is simply viewed. It is good to do it.

Prior to the playback of the video of the automatic playback function, it is advisable to give an instruction to operate when the video can be played. If you have a function to notify you by performing at least one of audio output and drawing to the display means, such as "Play today's driving event video. If you can play it, press the button above!" good.

(12) It has a function to let the user input whether or not there is an abnormality in the video reproduced by the automatic reproduction function, and saves the input result as a history in association with the information for specifying the area of the reproduced recording means. It is preferable to have a function of determining the normality / abnormality of the recording means based on the history.
By doing so, it is possible to more reliably determine whether the recording means is normal or abnormal.

It is preferable to record the input result and the information for specifying the area of the reproduced recording means in association with each other as a history, and to determine the abnormality or normality of the card based on this history. For example, when it is detected that the button is pressed, it is advisable to record the history of normal recording (for example, the date and time and the sector number played back), and make a judgment based on this history. Alternatively, conversely, when it is detected that the button has been pressed, it is advisable to record a history of not being able to record normally (for example, the date and time and the sector number played back), and make a judgment based on this history.

If the automatically played back video is distorted or black, the user may be asked to input that fact. This reproduction range may be marked as a defective area, and writing may not be performed in the marked area thereafter. Further, since there is a possibility of a defect, a notification prompting a predetermined response such as the need to replace the recording means may be given.
(13) When the abnormality is determined, the display means may be provided with a function of displaying information including the URL of the information regarding the exchange of the recording means as information.

In this way, the user can immediately obtain information including the URL of the information regarding the exchange of the recording means in the vehicle.

When it is detected that the NTSC signal has changed from the input state to the non-input state, the monitor display function is automatically switched to the original display function.

The acceleration sensor 20 is provided inside the main unit 1 and is connected to the control unit 10. After fixing the main unit 1 to the vehicle (for example, after fixing as shown in FIG. 4B), the control unit 10 simultaneously presses both the first button 11p and the second button 11q of the remote controller 11 for 2 seconds or longer. If it is detected, make initial settings. In this initial setting, the vehicle is moved straight back and forth, and the direction in which acceleration is generated when the vehicle is moved back and forth is detected by the acceleration sensor 20, and the three axes (x-axis, y-axis, z-axis) of the acceleration sensor 20 and the vehicle are used. After detecting the correspondence with the front-rear direction of the vehicle, the acceleration sensor 20 outputs a value with the front-rear direction of the vehicle as the X-axis, the left-right direction of the vehicle as the Y-axis, and the vertical direction of the vehicle as the Z-axis. It is a setting process to be performed. The front direction is the positive direction of the X axis, the left direction is the positive direction of the Y axis, and the upward direction is the positive direction of the Z axis. As such an initial setting method, a known method can be used.
The speaker 21 is provided inside the main unit 1 and is connected to the control unit 10.

The control unit 10 includes a microcomputer including a CPU, ROM, RAM, flash memory, various peripheral circuits, interfaces, etc., and is connected to each unit described with reference to FIG. 1 via an interface for inputting or outputting each signal. ing. When the ACC of the vehicle is turned on, the control unit 10 starts the video recording operation. The control unit 10 expands the OS and the application program recorded in the flash memory on the RAM by the boot loader recorded in the ROM, and executes the OS and the application program on the RAM to perform various processes described below. Execute and realize various functions. The OS is a multitasking OS, and concurrency processing is realized by switching and executing various application programs.

When the ACC is ON, the control unit 10 acquires the signal states of the NMEA data from the GPS unit 12, the acceleration sensor 20, the brake lamp line 33, the left turn signal line 32, and the right turn signal line 31 as vehicle states at any time. A data / signal state recording process for recording these data and signal states in a file at predetermined time intervals (for example, 30 times per second) is performed on the memory card 2 mounted in the memory card slot 19. ..

Further, the control unit 10 acquires images of the front view camera 15, the rear view camera 13, and the additional camera 14 as a plurality of vehicle peripheral images and displays them on the display device 10, and data / signal state recording processing. A video / audio recording process is performed in which the vehicle state recorded by the camera and the images around the vehicle are time-synchronized and recorded on the memory card 2 as reproducible data.

The control unit 10 includes, as peripheral circuits, a video capture circuit that captures NTSC signals from the front view camera 15, the rear view camera 13, and the extension camera 14 as video data on the RAM. Further, the control unit 10 is provided with a video memory (VRAM) or the like as a peripheral circuit, and the drawing data drawn in the video memory is output as an NTSC signal to the display device 16 via an electronic switch described later. It has a generation circuit.

When the ACC is ON, the control unit 10 transfers the captured video data to the video memory at any time and performs a camera image display process for displaying the captured video data on the display device 16. As a default process, the camera image display process performs a process of outputting the image of the front view camera 15 to the display device 16. Further, in the camera image display processing, when the pressing of the first button 11p of the remote control 11 is detected, the image transferred to the video memory and displayed on the display device 16 is displayed on the front view camera 15, the extension camera 14, and the rear view camera. The process of switching the images in the order of 13 is performed.

Further, in the camera image display processing, when the image signal from the rear view camera 13 is input from the state where the image signal is not input, the image is transferred to the video memory and displayed on the display device 16. , After switching to the video from the rear view camera 13, when the video signal is no longer input to the video signal from the rear view camera 13, the video transferred to the video memory and displayed on the display device 16 is converted to the video from the rear view camera 13. Performs the process of switching to the video before switching.

By doing so, the driver can display the image captured by the rear view camera 13 in the display area 16a of the display device 16 as shown in FIG. 10 simply by setting the shift position to the back, and can display the image at the rear of the vehicle. The situation can be confirmed by looking at the display device 16. In this way, the control unit 10 determines and outputs the image to be output preferentially to the display device 16 based on the operation state of the vehicle by the driver, so that the driver switches the image with the remote controller 11 together with the driving operation. There is no need, and the image of the direction to be driven will be output, and the appropriate image according to the driver's intention will be displayed at the appropriate timing.

In the video / audio recording process, after the power is turned on, the audio acquired from the built-in microphone 17 and the audio data acquired from the external microphone 18 are recorded together with the video data captured by the front view camera 15, the rear view camera 13, and the additional camera 14. It is a process to do. For each of the video data of the front view camera 15, the video data of the rear view camera 13, and the video data of the additional camera 14, the audio data acquired from the built-in microphone 17 is the left channel, and the audio data acquired from the external microphone 18 is the right channel. As a result, it is encoded in MPEG format and recorded in three files. The recording of these files is terminated when the control unit 10 detects that the supply of the ACC power supply to the main body has been cut off. This point will be described in detail later.

The file name of the signal state file recorded by the data / signal state recording process and the file names of the three MPEG files recorded by the video / audio recording process are obtained from the real-time clock (clock) provided as the peripheral circuit of the microcomputer in each process. Record the file using the date and time when the recording started. Therefore, by reading the date and time of this file name, the position recorded at the same date and time of the data of each file can be specified. Therefore, it is possible to perform a reproduction process in which these files are reproduced while maintaining temporal synchronization.

When the control unit 10 detects that the second button 11q of the remote controller 11 is pressed and held (continuously pressed for 2 seconds or longer), the control unit 10 reproduces the video and audio of the front view camera 15 from the beginning of the MPEG file currently being recorded. Start the playback process (start the so-called chase playback that plays while recording). For a certain period of time (5 seconds) from the start of the reproduction process, as shown in FIG. 11, the operation help 82, the camera information 85 of the reproduction image, the reproduction state 84, and the reproduction image date / time 83 are displayed by superimposing the reproduction image 81 on the reproduction image 81. .. These displays are performed for a predetermined time (3 seconds) even when the pressing of any button of the remote controller 11 is detected during the reproduction process.

The operation help 82 indicates what kind of processing is performed when which button of the remote controller 11 is pressed. As shown in FIG. 11, the correspondence between the button position of the remote controller 11 in the state where the remote controller 11 of FIG. 9 is rotated 45 degrees clockwise and the processing content is shown, and when the button shown in black in the figure is pressed, it is shown. , Indicates that the process described in characters on the right side is executed. For example, the button shown in black in the schematic diagram of the remote controller 11 on the left side of the portion drawn as "play / stop / slow" in FIG. 11 corresponds to the second button 11q, and only the second button 11q is pressed. Is detected, the screen display process (that is, the content of the reproduction process of the control unit 10) is switched in the order of reproduction → stop → slow. The current screen display processing state is displayed in the playback state 84 as "playing", "stopping", or "slowing". Further, information indicating which camera is the camera that recorded the currently reproduced image is displayed as the camera information 85. The camera information 85 is "CAM1" while displaying the image of the file recorded by the front view camera 15, "CAM2" while displaying the image of the file recorded by the extension camera 14, and the file recorded by the rear view camera 13. "REAR" is displayed while the image of is being displayed. The playback video date / time 83 is an area for displaying the video date / time of the displayed file, and the recording date / time at the beginning of the file acquired from the file name and the recording date / time of the currently displayed frame based on the frame information of the file. Is displayed.

When it is detected that only the first button 11p is pressed during the playback process, the file to be played back is switched, and the video is played back from the frame having the same date and time as the currently playing frame. By doing so, even if the file to be played is switched, the video will be displayed continuously in time. As a result, the playback video date and time 83 will continue to progress even if the file to be played back is switched.
If it is detected that only the third button 11r is pressed during the playback process, the playback process is terminated and the camera image display process is performed (playback end).

When the simultaneous pressing of the second button 11q and the third button 11r is detected during the reproduction process, the file to be reproduced itself is switched from the file currently being reproduced to the one older file. That is, with reference to the file name, the file recorded immediately before the file currently being played is specified from the date and time included in the file name, and the video is played from the beginning of the file. If there is no file older than the currently playing file, the currently playing file is played from the beginning.

When the simultaneous pressing of the first button 11p and the second button 11q is detected during the reproduction process, the file to be reproduced itself is switched from the file currently being reproduced to a new file. That is, with reference to the file name, the file recorded one after the file currently being played is specified from the date and time included in the file name, and the video is played from the beginning of the file. If there is no newer file than the currently playing file, the currently playing file is played from the beginning.

In this way, by operating the remote control 11, the images of the front view camera 15, the extension camera 14, and the rear view camera 13 can be switched to display the desired current image on the display device 16, or the front view camera 15, the extension camera 14 can be displayed. , The image taken by the rear view camera 13 and already recorded in the memory card 2 is reproduced, and the reproduced image of the front view camera 15, the extension camera 14, and the rear view camera 13 is switched by the operation of the remote control 11, and the desired past The image of the above can be displayed on the display device 16. The control unit 10 controls to switch only the video of at least one of the vehicle peripheral images acquired in this way or the video of at least any one recorded on the memory card 2 to the reproduced video.

Next, the end of recording of the above-mentioned file will be described in detail. The end of file recording is performed when the control unit 10 detects that the supply of the ACC power supply to the main body has been cut off. Specifically, when the cutoff of the ACC power supply is detected, the OS notifies each recording process, and the process of ending the recording of all files is executed. Therefore, each recording file is generated between the power-on by ACCON of the vehicle and the power-off by ACCOFF.

When the ACC power supply is cut off, the control unit 18 closes all the files in this way and then performs a reproduction process when the power supply is cut off. The reproduction process when the power is cut off is the time when the acceleration changes in a predetermined pattern in the direction retroactive from the current time of the history of the value of the acceleration sensor 20 recorded on the memory card 2 in the data / signal state recording process. Explore. In the present embodiment, as a predetermined pattern, a time when the acceleration in the front-rear direction changes from less than a predetermined value to a predetermined value or more is searched, and the total of the time points from 5 seconds before to 5 seconds after the searched time. A process is performed in which the recorded video data for the memory card 2 of the front view camera for 10 seconds is read out, expanded in the memory, and output as a video signal to the display device 16. In the present embodiment, the absolute value of the acceleration is used as the predetermined value of the acceleration, and the absolute value is 0.4 G. When the reproduction of the video for a total of 10 seconds is completed, the power supply from the built-in battery to each part is controlled to be turned off, and the power is turned off.

By doing so, the user can operate the vehicle to switch from the runnable state to the non-runnable state, and in the present embodiment, simply turning off the engine of the vehicle is performed from the recorded camera recorded on the memory card 2. Among the images, you can see the images from 5 seconds before to 5 seconds after the time when the absolute value of the acceleration in the front-back direction changed from less than 0.4 G to 0.4 G or more in the past from the present time to the latest. Therefore, you can see the image of the latest sudden braking or sudden start before turning off the engine without any operation just by turning off the engine. Therefore, it is possible to easily raise awareness of safe driving when the memory is new. Further, it is possible to easily know whether the video is properly recorded on the memory card 2 without the user operating the play button or the like to check whether the video recorded on the memory card 2 is properly played. .. Further, it is not necessary for the user to operate the play button or the like to periodically check whether the video recorded on the memory card 2 is properly played back. Moreover, the user does not have to operate the play button. As a result, it is possible to reduce the possibility that the image is not properly recorded on the memory card 2 only when a vehicle accident or the like actually occurs and it becomes necessary to reproduce the image. Since the power is automatically turned off after the playback is completed, the user does not need to turn off the power, which saves time and effort.

In the present embodiment, the user changes the key of the vehicle from the engine on state to the engine off position in the detection of the vehicle operation of the user who switches the vehicle from the runnable state to the non-runnable state. Is determined by the fact that the power supply state to the ACC system power supply is changed from on to off, but it is not limited to this, for example, the push start switch of the vehicle is turned off in the push start vehicle, and the vehicle It is also possible to input and detect by branching the signal line of the vehicle that outputs that the key is operated and the engine or the like is turned off.

This device may be a device that is retrofitted to the vehicle after being shipped from the vehicle manufacturer's factory. In the present embodiment, the present device is distributed in a plurality of housings to have a partial configuration thereof, but it is particularly preferable to house the apparatus in one housing as much as possible. Further, it is preferable that the display device 16 is also housed in the housing of 1. Although the vehicle is a four-wheeled vehicle in the present embodiment, it may be a special vehicle such as a forklift, but it may be a vehicle having wheels exceeding four wheels in particular.

"Installation" is often configured to be installed in the vehicle after the vehicle manufacturer ships from the factory. In this embodiment, the housing is directly attached to the vehicle interior with double-sided tape and fixed. It may be configured so that it can be fixedly installed by pasting a mounting tool or the like attached to the above or fixing it with a screw.

In the present embodiment, the cameras are a front view camera 15, a rear view camera 13, and an additional camera 14, but in particular, a camera that shoots the front of the vehicle, a camera that mainly shoots an area other than the front, and a camera that shoots the driver. It may be at least one of. The number of cameras may be one, but as in the present embodiment, it is preferable to provide a plurality of cameras and record the images of the plurality of cameras in synchronization with each other so as to be playable. For example, as in the present embodiment, it is preferable to store each video data in association with the time data acquired from the GPS unit 12 or the like with the video data from the camera. Further, it may be provided with a function of simultaneously playing back the video data corresponding to the time data of the same time stored in association with each video data. In this case, the screen may be divided into areas for reproducing the images of each camera, and the recorded images of each camera may be synchronized and reproduced in each area. For example, the screen is divided into four parts, the upper left screen area is the image recorded from the front view camera 15, the upper right screen area is the image recorded from the expansion camera 14, and the lower left screen area is the image recorded from the rear view camera 13. It is preferable to display the time data of the video being played back recorded by the data / signal state recording process in the lower right screen area.

In the present embodiment, the rear view camera 13 is configured to supply power to the brake lamp line, but it is also configured to constantly supply power like other cameras and switch the image according to the state of the brake lamp line. good.

In this embodiment, the image is constantly recorded from ACCON to ACCOFF, but the state corresponding to the collision of the vehicle is determined by the acceleration sensor 20 while not always recording or constantly recording. When detected, the memory card 2 is recorded with the vehicle state and the vehicle peripheral image acquired from the front view camera 15, the rear view camera 13, and the extension camera 14, regardless of the image output to the display device 16. It may be configured to perform event recording processing.

The video in a predetermined range may be a video constantly recorded as in the present embodiment, but it is particularly preferable to include a video recorded at an event. By doing so, the user can automatically perform the video at the time of the event occurrence only by performing an operation of cutting off the power supply from the vehicle to the device.

As the event record, various events other than the shock generation event of the occurrence of a shock may be used. Further, in the present embodiment, it is decided to record an image of the rear view camera 15 or the like for photographing the rear of the vehicle, but the present invention is not limited to this, and an arbitrary image may be recorded, and the operating state of the vehicle is also an arbitrary state. May be acquired and recorded.

For example, a side camera for acquiring a vehicle right image and a vehicle left image is provided, respectively, and the control unit 10 is connected to the vehicle LAN, and the driver operates the vehicle at a predetermined vehicle speed or less (for example, from a packet flowing through the vehicle LAN). When it is detected that the right turn signal is output in the state of 10 km / h or less), the control is performed to output the image on the right side of the vehicle with priority over other images, and the vehicle is recorded as a right turn event, while being recorded as a predetermined value. When it is detected that the left turn signal is put out at a vehicle speed or less (for example, 10 km / h or less), the left side image of the vehicle is controlled to be output with priority over other images, and the event is recorded as a left turn event. .. By doing so, for example, when leaving the parking lot in either the left or right direction, or when trying to turn at an intersection with poor visibility, the area around the vehicle in the direction in which the turn signal is put out at a speed below a predetermined vehicle speed. The image is displayed on the display device 16, and the image at that time is recorded on the memory card 2. Therefore, the driver can easily check the image when turning right in the past by looking at the display device 16 without performing a special operation for reproduction only by performing an operation such as turning off the engine.

In this embodiment, the memory card 2 is used for recording. The memory card 2 may be particularly a non-volatile memory, and may be particularly configured to include a non-volatile memory having a life shorter than that of a DRAM or the like. The memory card 2 may be configured to include a NAND flash memory in particular. Instead of the memory card 2, a memory fixed to a substrate or the like inside the housing of the device may be used, but it is particularly preferable to use a recording medium that can be attached to and detached from the device as in the present embodiment. In particular, as in the present embodiment, a card-shaped recording medium may be used, and in particular, an SD card or a micro SD card may be used.

In the present embodiment, the detection of the detection of the user's vehicle operation for switching the vehicle from the runnable state to the non-runnable state is performed based on the fact that the power supply from the vehicle to the main unit 1 is cut off, and the vehicle to the main unit 1 is detected. It has a function to continue operation by supplying power from the backup power supply built in the main unit 1 when the power supply from the vehicle is cut off, and the memory card responds to the power supply from the vehicle being cut off. It is configured to have an automatic reproduction function for reproducing a predetermined range of images among the recorded images recorded in 2. By doing so, when the power supply from the vehicle to the main unit 1 is cut off, a predetermined range of the recorded images recorded on the memory card 2 is automatically reproduced in the vehicle. Therefore, the user does not need to operate the play button or the like of the device to confirm whether the video recorded in the recording means is played properly, and is automatically performed when the power supply to the main unit 1 is simply cut off. It is possible to confirm whether the recording on the memory card 2 is properly performed only by looking at the image reproduced and displayed on the display device 16.

It was decided to determine that the power supply from the vehicle was cut off based on the presence or absence of power supply to the ACC power supply, but the ACC power supply is the wiring of the vehicle itself, the fuse box of the vehicle, etc. It may be obtained by branching from, but it is particularly preferable to receive the supply from the cigar socket of the vehicle.

In the present embodiment, the built-in battery built in the main unit 1 is configured to operate even when the ACC system power is turned off, but it is another battery or the like provided externally and is a car battery for controlling the vehicle itself. It is preferable to use a battery different from the one used as a backup power source to receive power. For example, it may be powered by a mobile battery.

In the present embodiment, the built-in battery built in the main unit 1 is configured to operate even when the ACC system power is turned off, but in particular, the car battery 91 for supplying the electric power required for starting the vehicle itself to each part of the vehicle. It is connected to a signal line on the vehicle side that can determine when the power supply from the vehicle is cut off, for example, the power line of the cigar socket, and the signal state of the signal line is used for determination. May be good.

In the present embodiment, the recording of the image from the camera to the memory card 2 is stopped and the automatic reproduction is performed when the power supply from the vehicle to the main unit 1 is cut off. In the present embodiment, the image from each camera to the memory card 2 is detected in response to the detection of the user's vehicle operation of switching the vehicle from the runnable state to the non-runnable state, that is, the key of the vehicle is operated and the engine is turned off. It is provided with a function of stopping the recording of the image and automatically playing back the recorded image on the memory card 2 of the front view camera 15. By doing so, it is not necessary to record the video of each camera and play back the recorded video at the same time, the processing load and power consumption can be reduced, and the recorded video during running before switching to the non-running state can be achieved. Can be automatically regenerated according to the detection of the user's vehicle operation for switching the vehicle from the runnable state to the non-runnable state.

In the present embodiment, the power is turned off after the automatic playback is completed, but the parking is performed differently from the running video recording mode in which the power is not turned off after the automatic playback is completed and the recording is performed in a runnable state. In the time recording mode, the image from each camera may be recorded on the memory card 2. This recording mode may be a known mode called a parking monitoring mode or the like.

By doing so, the user simply operates the vehicle to switch the vehicle from the runnable state to the non-runnable state, and can obtain a predetermined range of images from the recorded camera recorded on the memory card 2. It can be automatically played back, and after the automatic playback is completed, recording in the parking recording mode can be automatically executed without any operation.

As the parking recording mode, for example, it is preferable that the parking recording mode adopts a recording method that suppresses the power consumption of the device rather than the traveling video recording mode. For example, it may be better to lower the frame rate in the parking recording mode than in the running video recording mode, or to record the video only when an impact is detected.

For example, it is preferable to enter a parking recording mode that allows the camera to continue to operate by supplying power from the backup power supply even after the automatic playback is completed and to record the image from the camera to the memory card 2.

In the present embodiment, it is decided to reproduce the image from 5 seconds before to 5 seconds after the time when the absolute value of the acceleration in the front-back direction changes in a predetermined pattern in the past from the present time to the latest, but the predetermined past. The image is not limited to the above range, and may be an image recorded in the period of the travelable state immediately before the user's vehicle operation for switching the vehicle from the travelable state to the non-travelable state is detected as the image of the predetermined range. By doing so, the user simply operates the vehicle to switch the vehicle from the runnable state to the non-runnable state, and is in the immediately preceding runnable state of the recorded images from the camera recorded on the memory card 2. The video recorded during the period can be automatically reproduced and displayed on the display device 16. Therefore, this time, when the user switches the vehicle to the non-driving state, the image of the driving in the latest driving unit between the time when the vehicle is switched from the runnable state to the non-running state is automatically and easily displayed. The user can confirm. Therefore, for example, it is possible to easily confirm on the spot from the driver's seat by a video while the memory of one's own driving is clear, for example, whether or not one's own driving this time was appropriate. For example, it has a function to make an image for a predetermined period within the vehicle power supply range at the time when the power supply from the vehicle to the main unit 1 is started immediately before the power supply from the vehicle to the main unit 1 is cut off. You may do so.

Then, if there is no image of the target recorded in the period of the runnable state immediately before the user's vehicle operation for switching the vehicle from the runnable state to the non-runnable state is detected, it is recorded in the previous vehicle power supply range. It may be provided with a function of sequentially searching and playing back the video. For example, in the case of a configuration in which the target video is an event-recorded video, the "predetermined period" is the video if there is an event record during the current driving period, and if there is no event recording during the current driving period. , It is preferable to have a function to search retroactively to the previous running period. For example, if you use a car to commute from your home to the office, if you start the engine at the office and turn off the engine at your home when you return home from the office today, if there is no event record as the target video in the meantime Before that, I started the engine at home and searched the range where the engine was turned off at the company during the main sunrise shift. If there is no event record in this range, it is advisable to search and play back in sequence, such as when returning home the day before, when working at sunrise the day before, and so on.

For example, if there is no image recorded on the memory card 2 in the vehicle power supply range for a predetermined period, the image recorded in the previous vehicle power supply range is searched from the memory card 2 and displayed on the display device 16 for reproduction. It is good to have a function to do.

As the video for a predetermined period, the video is always recorded in the present embodiment, but it is particularly preferable to include the video recorded at the event. By doing so, the user simply operates the vehicle to switch the vehicle from the runnable state to the non-runnable state, and the event recording of a predetermined range of the recorded images from the camera recorded on the memory card 2 is performed. The displayed image can be automatically reproduced and displayed on the display device 16.

The event recording may be configured to record, for example, when it is detected that a signal from a sensor or a switch has changed to a predetermined state. For example, the video recorded when it is determined that an event has occurred may be a video including the time when the event occurred, and in particular, a predetermined number of seconds before the event occurred (for example, 15 seconds), especially the event occurred. It is preferable to set the predetermined number of seconds (for example, 15 seconds + 20 seconds = 35 seconds) including the subsequent predetermined number of seconds (for example, 20 seconds).

The user simply operates the vehicle to switch the vehicle from the runnable state to the non-runnable state, and automatically reproduces a predetermined range of the recorded event-recorded images recorded in the recording means. Can be done.
It is preferable to have a function of reproducing only a part of the recorded time of the event-recorded video without reproducing the entire range of the recording time recorded corresponding to the event.

In this way, the user can grasp the outline of the video recorded in the event in the vehicle in a short time. In particular, when the user operates the vehicle to switch the vehicle from the runnable state to the non-runnable state, the user may get off the vehicle in a relatively short time thereafter. It is possible to easily confirm in a short time until this disembarkation.

For example, when the event recording is configured to record a total of 35 seconds of video including 15 seconds before the event occurs and 20 seconds after the event occurs, as a partial range, for example, 10 seconds before the event occurs. It is advisable to reproduce a total of 15 seconds, which is 5 seconds after the event occurs. In particular, as a partial range, if the number of playback seconds before the event occurs is longer than the number of playback seconds after the event occurs, even if it is not possible to turn your eyes to the display means immediately after the start of playback, when the event occurs. It is good because it increases the possibility that you can check the image of.

As a partial range, the number of seconds of the moving image should be within 15 seconds. By doing this, you can easily upload to SNS such as Tiktok by taking a picture of the display means with a smartphone.

It would be nice to be able to set the number of seconds for a part of the video. In particular, it is preferable to have a function to store the number of seconds for each type of SNS in the device in advance and set the number of seconds to be played as a partial range by the user selecting the type of SNS.
As a function of reproducing only a part of the range, it is preferable to have a function of setting the reproduction start position of the video recorded in the event.

For example, it is preferable to start the reproduction from the position after a predetermined number of seconds (for example, 5 seconds) from the beginning of the event recording. For example, it is preferable to have a function to set the number of seconds before and after the event occurrence position (for example, the trigger position) as the starting point.

It is preferable to have a function to continuously play back the video recorded at a plurality of events. By doing so, the user simply operates the vehicle to switch the vehicle from the runnable state to the non-runnable state, and continuously captures the images of a plurality of event records recorded by the recording means from the recorded cameras. It can be played automatically.
In particular, it is preferable to have a function of continuously playing a part of a plurality of images.

Further, in the playback process when the power is cut off, it is provided with a function of causing the user to input whether or not there is an abnormality in the video reproduced by the automatic playback function, and a function of determining the normality / abnormality of the recording means based on the input result. good. For example, if the press of the first button 11p is detected during playback in the playback process when the power is cut off, the video being played is normal, and if the press of the second button 11q is detected, the video is being played. The image is judged to be abnormal. By doing so, every time the vehicle is operated to switch the vehicle from the runnable state to the non-runnable state, the recorded image from the recorded camera recorded on the memory card 2 is automatically played back. Therefore, the user can be made to input whether or not there is an abnormality in the video reproduced by this automatic reproduction function, and the normality / abnormality of the memory card 2 can be determined based on the input result.

In particular, the function of letting the user input whether or not there is an abnormality in the video played by the automatic playback function is a function of inputting an instruction indicating that the video has been viewed, in particular, when the automatically played video is simply viewed. May be. For example, it is advisable to assign a function for inputting an instruction to be seen to the first button 11p. It can be determined that at least the range in which this instruction is input is normal.

Prior to the playback of the video of the automatic playback function, it is advisable to give an instruction to operate when the video can be played. For example, the control unit 10 outputs a sound from the speaker 21 and draws a character string on the display device 16 such as "Play today's driving event video. If it can be played, press the upper button!". It is advisable to start automatic playback after notifying the user.

It has a function to let the user input whether there is any abnormality in the video played by the automatic playback function, and saves the input result in the memory card 2 as a history by associating the information for specifying the area of the played memory card 2. However, it is preferable to have a function of determining normality / abnormality of the memory card 2 based on the history. By doing so, it is possible to more reliably determine whether the recording means is normal or abnormal.

It is assumed that the control unit 10 records the input result and the information for specifying the regenerated memory card 2 area in the memory card 2 as a history in association with each other, and determines whether the card is abnormal or normal based on this history. good. For example, when it is detected that the button is pressed, it is advisable to record the history of normal recording (for example, the date and time and the sector number played back), and make a judgment based on this history. Or conversely, when it is detected that the button is pressed, the history that it could not be recorded normally (for example, the date and time and the sector number played back) is recorded in the memory card 2, and the judgment is made based on this history. It is good to set it to.

When the automatically reproduced reproduced image is distorted or completely black, the user may be made to input to that effect from the second button 11q or the like. This reproduction range may be marked as a defective area and stored in the memory card 2, and the marked area may not be written thereafter. Further, since there is a possibility of a defect, the speaker 21, the display device 16 or the like may give a notification prompting a predetermined response such as the need to replace the memory card 2.

If it is determined that the abnormality is determined, the display device 16 may be provided with a function of displaying information including the URL of the information regarding the replacement of the memory card 2. In this way, the user can immediately obtain information including the URL of the information regarding the exchange of the recording means in the vehicle. As the information including the URL of the information related to the exchange of the recording means, the URL or QR code of the purchase site of the memory card 2 of the part number recommended for the device is displayed, or the memory card 2 is the exchange time. It is good to display it. By doing so, it becomes possible to easily go to the store of the memory card 2 while riding in the vehicle, and the problem that the image of the camera of the vehicle is not recorded while the memory card 2 is abnormal occurs extremely. It can be resolved quickly.

Further, it may be provided with a function of performing a trial writing on the area around the area in which the image determined to be abnormal is recorded and determining whether or not there is a high possibility of failure of the memory card 2. By doing so, it is possible to more reliably determine whether or not there is an abnormality in the memory card 2. For example, in the present embodiment, a time when the acceleration in the front-rear direction changes from less than a predetermined value to more than a predetermined value is searched for, and a total of 10 seconds from the time point 5 seconds before the searched time to the time point 5 seconds after the searched time. It was decided to read the recorded video data for the memory card 2 of the front view camera, expand it to the memory, and output it as a video signal to the display device 16. For example, when FAT is adopted for the file system of the memory card 2. , 1 before and after each sector in which this total of 10 seconds of video was recorded (in FAT, sectors may be recorded in a discrete manner, and which sector is recorded in the management area etc.) Search for a sector that is a free sector in which no other file is recorded, write and read to the searched sector, and if the written data and the read data match, it is normal. If they do not match, it may be determined as abnormal.

Also, for example, for the area around the area marked as abnormal, whether there is an abnormality in most of the recording means by trial writing the data, or whether the part that happened to be played back is broken. The presence or absence of an abnormality may be determined based on the above.

It is preferable to have a function of prompting the user to input whether or not to erase the video played by the automatic playback function, and to have a function of erasing the automatically played video when an instruction to erase is input. For example, if the pressing of the third button 11r is detected during or after the reproduction by the automatic reproduction function before the power cutoff process is performed, it is preferable to perform the process of erasing the image. The range to be erased may be the replayed range, but in particular, when the video is recorded in a file in a predetermined time unit, the process of deleting the file including the automatically replayed range may be performed. When the event recording is automatically reproduced, the entire event recording including the reproduction range may be deleted. By doing so, it is possible to quickly erase unnecessary images in the vehicle from the images stored in the memory card 2 and extend the recordable time thereafter. For example, a notification asking whether to erase the played video is output to the speaker 21 and the display device 16, and when an instruction to turn off within a predetermined time (within 10 seconds) is input from the third button 11r, the played video is output. It is good to have a configuration to erase.
The functions of the first to third buttons may be assigned different functions in the case of the reproduction process by a normal user operation and the reproduction process when the power is cut off.

The auto-playback function has a function to continuously and automatically play back different ranges of video, and has a function to let the user input whether or not to erase the continuously automatically played-back video by the auto-playback function. When an instruction is input, it is preferable to have a function of erasing the range of continuously automatically reproduced video by the automatically reproduced automatic reproduction function. By doing so, it is possible to easily and quickly erase images in different ranges that are continuously and automatically reproduced by a single operation. For example, the user is asked by the audio output from the speaker 20 and the display of the character string on the display device 16 whether to erase all the continuously played images at once when the continuous playback is performed by automatic playback. , When an instruction to erase within a predetermined time (within 10 seconds) is input from the third button 11r, it is preferable to have a function of erasing a series of images at once.

The automatic reproduction function may be provided with a function of reproducing the images of a plurality of cameras recorded on the memory card 2 so as to be displayed on the display device 16 at the same time. As a plurality of cameras, for example, both a rear camera and a front camera may be used.

A communication module such as LTE / WiFi is connected to the control unit 10 to have a connection function to the Internet, and instead of the automatic playback function, or together with the automatic playback function, the acceleration in the front-back direction is from less than a predetermined value to more than a predetermined value. The time changed to is searched, and the recorded video data for the memory card 2 of the front view camera for a total of 10 seconds from the time point 5 seconds before the searched time to the time point 5 seconds after the searched time is read out and specified on the Internet. It is good to have an automatic SNS upload function to upload to SNS. By doing so, the user simply operates the vehicle to switch the vehicle from the runnable state to the non-runnable state, and automatically obtains a predetermined range of images from the recorded cameras recorded in the recording means. Can be uploaded to SNS. Therefore, it is not necessary for the user to operate the play button or the like of the device to upload the video recorded on the memory card 2. Moreover, since the video uploaded to this SNS can be easily confirmed on a smartphone or the like, the user operates the play button of the device or the like to periodically check whether the video recorded on the recording means is properly played. You don't even have to check. Moreover, the user does not have to operate the play button of the device. As a result, it is possible to reduce the possibility that the image is not properly recorded in the recording means only when a vehicle accident or the like actually occurs and it becomes necessary to reproduce the image.
For example, in addition to the above conditions, SNS may be uploaded when communication is established, such as when a car enters the garage at home and can connect to WiFi at home.

It is preferable to have a function of connecting to a smartphone by WiFi and to have an automatic smartphone upload function for automatically uploading to a smartphone in place of the automatic playback function or in addition to the above-mentioned automatic playback function. By doing so, the user simply operates the vehicle to switch the vehicle from the travelable state to the non-travelable state, and the image of a predetermined range of the images recorded from the recorded camera recorded on the memory card 2 is displayed. It can be automatically uploaded to a smartphone. Therefore, it is not necessary for the user to operate the play button or the like of the device to upload the video recorded by the recording means. Moreover, since the video uploaded to this smartphone can be easily confirmed on a smartphone or the like, the user operates the play button or the like of the device to periodically check whether the video recorded on the memory card 2 is properly played. There is no need to check with. Moreover, the user does not have to operate the play button of the device. As a result, it is possible to reduce the possibility that the image is not properly recorded in the recording means only when a vehicle accident or the like actually occurs and it becomes necessary to reproduce the image. For example, it may be provided with a connection function to a smartphone and automatically uploaded to the camera roll of the smartphone.

The function of the remote controller 11 may be realized by a smartphone application instead of the remote controller, and the information may be sent between the smartphone and the present device via communication such as WiFi. A smartphone application having the functions of the first button 11p, the second button 11q, the third button 11r, the first lamp 11x, and the second lamp 12y may be provided.

Record for card 2. By doing so, it is possible to reliably record a plurality of images around the vehicle at the time of a collision.

When reproducing the data of the vehicle peripheral image recorded on the memory card 2, it is preferable to have a function of reversing the reproduced image horizontally or vertically. By doing so, even if the camera that captures the image around the vehicle is installed upside down, the image can be reproduced in the correct direction. Further, for example, an image taken by a rear view camera that outputs a video signal of a horizontally inverted image can be reproduced by being horizontally inverted.

It is preferable that the memory card 2 records the operation state of the vehicle by the driver, the acquired vehicle state, and the plurality of vehicle peripheral images as reproducible data in time synchronization. For example, by recording what the shift position is as the operation state of the vehicle by the driver, the engine brake is applied on the downhill, which is hit during the back, or the vehicle is stopped, neutral or parked. (ECO operation) etc. can be understood. Then, the information indicating the image preferentially output to the display device 16, the operation state of the vehicle by the driver, the acquired vehicle state, and the plurality of vehicle peripheral images are stored in memory as data that can be reproduced in synchronization with time. It is advisable to perform a process of recording on the card 2.

The data recorded in the memory card 2 can be reproduced by taking out the memory card 2 from the memory card slot 19, inserting it into a personal computer, and using a program on the personal computer. For example, the viewer screen 100 as shown in FIG. 12 is displayed by processing by a program on a personal computer.
