Summary of the Invention

Problems to be Solved by the Invention

[0004] As an example of the video captured by the front monitoring camera of the drive recorder disclosed in Patent Document 1, as shown in FIG. 8 of Patent Document 1 where a state in which a preceding vehicle is displayed is drawn, the angle of view is relatively narrow, and a certain range in front of the vehicle is captured. In paragraph

[0077] of Patent Document 1, it is shown that the in-vehicle monitoring camera is composed of a lens with a narrower angle of view than the front monitoring camera. Thus, the conventional drive recorder has various problems such as the captured range being narrow and limited to the front, and the range of the video to be recorded being insufficient. Therefore, an object is to provide something better than the conventional one.

[0005] The purpose of the present invention is not limited thereto, and the applicant intends to obtain rights through divisional applications, amendments, etc., for configurations that aim to obtain the effects derived from the components of the configuration disclosed in this specification and the drawings, etc. For example, problems that can be described as "can be achieved" in this specification are disclosed here by reinterpreting them as "the problem is...". Each problem is described independently, and the applicant intends to obtain rights to the configurations for solving these problems individually through divisional applications, amendments, etc. Even if a problem is implicitly understood from the description in the specification, the applicant intends to include a part of the configuration described in this specification in the claims through amendment or divisional application. Furthermore, problems that combine these independent problems are also disclosed. [Means for solving the problem]

[0006] (1) A device that is installed on a vehicle afterwards, comprising a camera that photographs an area outside the vehicle other than the front of the vehicle, and means for outputting the image captured by the camera to a recording unit that records the image.

[0007] If equipment / systems with such configurations are installed in a vehicle afterward, recording can be made even if the vehicle is hit by another vehicle from a direction other than the front, even if the vehicle did not originally have such equipment. The recording unit to which the video is output may be configured to be fixed to or detachably mounted on the housing in which the camera is mounted, but it is preferable not to mount it on the housing in which the camera is mounted. Not mounting the recording unit on the housing in which the camera is mounted allows for further miniaturization of the camera housing, which is preferable as it does not obstruct the driver's view. If the recording unit is not mounted on the housing in which the camera is mounted, the recording unit may be mounted in a separate housing, for example, and placed in the vehicle, but it is better to use the cloud. Filming areas outside the vehicle includes, for example, filming the outside of the vehicle through the interior of the vehicle.

[0008] "Installed on the vehicle afterwards" means, for example, after the vehicle leaves the factory from the manufacturer, and more preferably, after purchase from a dealer. "A camera that photographs areas outside the vehicle other than the front" means, for example, one that does not primarily photograph the front, and does not include, for example, a camera whose optical axis axis, central axis axis, or the center of the shooting means is facing the front of the vehicle, and in particular, one whose shooting area does not include the front. Furthermore, "a camera that photographs areas outside the vehicle other than the front" may also include, for example, a camera that photographs areas outside the vehicle other than the front, including the front. In such cases, the camera that photographs areas outside the vehicle other than the front should be a camera that photographs areas other than the front of the vehicle more extensively than the front of the vehicle, and for example, in the case of a 360-degree camera, it should be installed in a position that photographs the rear side more, such as the rear of the vehicle interior.

[0009] This system functions, for example, as a dashcam with a rear-facing camera, if the camera that captures areas outside the vehicle other than the front of the vehicle is also used to capture the area behind the vehicle. For example, the camera that captures the rear should be made smaller by having a resolution of, for example, 1 to 2 megapixels. Furthermore, it would be good to widen the camera's field of view to capture a wider area.

[0010] (2) The vehicle may be equipped with a means for detecting danger based on images captured by a camera that captures areas outside the vehicle other than the front of the vehicle, and outputting this information to the notification unit. In this way, the driver is looking ahead while driving and cannot pay attention to or confirm what is happening outside the vehicle other than in front of the vehicle, but the system will notify the driver of dangers occurring in directions other than in front of the vehicle, making it easier for the driver to take action to avoid those dangers.

[0011] The dangers to be detected should, for example, be the approach of surrounding vehicles such as following vehicles. This is good because, for example, the presence of a vehicle approaching from behind can be detected and an alert can be issued. Since drivers cannot constantly look behind them while driving, for example, if the driver is looking ahead and is notified of the approach of a following vehicle, the alert can prompt them to check the situation behind them using the rearview mirror or other means.

[0012] Detection of vehicles approaching from behind should ideally be based on the distance to other vehicles around the vehicle, such as those behind it. For example, a baseline distance could be set, and a notification could be issued when surrounding vehicles approach below this baseline distance. Furthermore, this proximity-based alert should be conditional, such as only triggering when traveling at a certain speed or higher. For example, to alert of a vehicle that has approached to a certain extent while driving, the baseline distance needs to be set to an appropriate length. In this case, if an alert sounds every time a vehicle approaches while stopped in traffic, at an intersection, or at a traffic light, it could become cumbersome and unusable. However, by setting the alert to occur only when traveling at a certain speed or higher, alerts will not be triggered when the vehicle is stopped, slowing down to stop, or traveling at a low speed due to traffic congestion.

[0013] In addition to the above, it is good to set multiple reference distances, for example, depending on the vehicle's speed. This way, for example, by making the reference distance for speeds corresponding to driving on highways longer than the reference distance for speeds corresponding to driving on general roads, it is possible to receive a notification even when the following vehicle is approaching at a relatively large distance compared to when driving on general roads. Also, for example, by setting a shorter reference distance when the vehicle speed is 0 or low, it is possible to achieve the same effect as the above-mentioned alerts that are limited to driving above a certain speed, such as not notifying or giving a mild notification when a following vehicle approaches while stopped in traffic, at an intersection, or waiting at a traffic light. The determination of whether or not it is a reference distance can be based on a direct measurement such as XX meters, but it is better to base it on something equivalent to XX meters, such as the size of the vehicle in a captured image.

[0014] Furthermore, the dangers to be detected should include, for example, aggressive driving by surrounding vehicles. Aggressive driving can be detected, for example, based on changes in the distance between your vehicle and the vehicle behind it, or based on driving patterns such as the movement of the vehicle as captured by a camera. For judgments based on changes in the distance between vehicles, for example, if the vehicle suddenly closes the distance between vehicles, it should be judged as aggressive driving. In addition, for driving patterns, for example, if a driving pattern of suddenly approaching and a driving pattern of swerving from side to side after approaching are recognized, it should be detected as aggressive driving or dangerous driving.

[0015] In addition to a function that alerts the driver when aggressive driving occurs, or as an alternative to this alert function, it would be good to have a function that saves a still image or video to a dedicated folder when the vehicle approaches rapidly. Saving to a dedicated folder allows the user to easily check the license plate number of the aggressive vehicle later by playing back the still image or video saved in that folder.

[0016] The function that detects and alerts about aggressive driving and approaching vehicles, as mentioned above, should ideally be implemented using a function similar to the forward collision prevention alert in active safety systems.

[0017] Furthermore, the hazards to be detected should ideally include moving objects such as children running into the road, or collisions with fixed objects. For example, it would be good to detect a child running into the road while the vehicle is reversing and issue an alert.

[0018] The notification unit may output sound from a speaker or other means, or it may be visually based from a display or monitor, but using sound is preferable. Sound-based notification is good because, for example, the driver can be aware of the notification even when they are looking ahead and not at a display or monitor. When using a monitor such as a display or monitor as the notification unit, it is good to place the monitor in a position where the driver can see it while driving, and it may be a dedicated monitor, but it is preferable to use a monitor from another device. Images of areas outside the vehicle other than the front, such as the rear, are not something that the driver needs to look at constantly or frequently while driving ahead. If there is a monitor from another device, installing a separate dedicated monitor in addition to that would result in multiple monitors, which may be more of a hindrance than a help, and it would be difficult to instantly know which monitor to look at. Therefore, it is preferable to use a monitor from another device to solve these problems. The monitor from another device may be, for example, a monitor from a system such as a drive recorder that films in different directions. In systems such as dashcams that record in different directions, for example, if the system records the front view, it would be beneficial to display an alert on the monitor that normally displays the front view footage when a vehicle behind approaches rapidly due to aggressive driving. The alert displayed in such cases may consist of text, graphics, or other patterns, but it is preferable to display the footage of the vehicle engaging in aggressive driving.

[0019] (3) The housing that mounts the camera that photographs areas outside the vehicle other than the front of the vehicle should not have a monitor, but should be equipped with a notification means to inform people inside the vehicle that it is operating. This way, the size can be reduced by not having a monitor. Without a monitor, it is unclear whether or not it is operating, which may cause anxiety for the user, but this anxiety can be alleviated by providing a notification means to inform people inside the vehicle that it is operating. The notification means may be a light-emitting element such as an LED or a speaker that outputs sound, but a light-emitting element such as an LED is good because it can be checked at an appropriate time. The notification means may be provided separately from the housing that mounts the camera, but it is better to provide it in the housing. Thus, the housing or separate unit that mounts the camera that photographs areas outside the vehicle other than the front of the vehicle, such as a rear camera, should only have an operation lamp and should not have a monitor.

[0020] (4) The camera that photographs the area outside the vehicle other than the front of the vehicle is to photograph the area behind the vehicle, and the housing that implements the camera that photographs the area outside the vehicle other than the front of the vehicle may be equipped with a mounting part that is attached to the ceiling of the passenger compartment on the rear window side of the vehicle. In this way, even in the case of a hatchback type vehicle or a glass hatch type vehicle where the rear window part opens and closes, the housing remains attached and does not move even when the back door or rear window is opened and closed, as long as the housing is attached to the ceiling of the passenger compartment.Therefore, for example, if a predetermined wiring is made to the housing, the wiring can be routed through the passenger compartment without becoming loose.In contrast, if the housing is attached by being attached to the rear window or the like, the housing will move together with the back door or rear window when it is opened and closed.For example, if the wiring is made to the housing, problems may arise in the routing of the wiring, such as having to leave some looseness in the wiring to prevent it from breaking when it is opened, but by attaching it to the ceiling, there is no need to worry about this. A standalone camera is acceptable for recording the rear of the vehicle, but it is preferable to install the rear camera of a 2-channel or higher dashcam on the ceiling inside the vehicle.

[0021] The mounting part may be, for example, a jig for mounting various mechanisms and structures, or in a simple configuration, it may be attached to the ceiling using adhesive material such as double-sided tape on the surface of the housing.

[0022] (5) Cameras that photograph areas outside the vehicle other than the front of the vehicle should be capable of night photography even when the vehicle's lights are not illuminating the area. Areas outside the vehicle other than the front of the vehicle are not illuminated by the vehicle's lights, but by using a night photography camera, it is possible to take bright, clear, and other images even at night. For example, areas behind and to the sides of the vehicle are dark because there are no vehicle lights, making them difficult to record at night, but this problem can be resolved. Night photography capability means that, at night, it is desirable to be able to photograph other vehicles such as following vehicles or other objects in a way that allows for identification. Identifiable photography means, for example, in the case of a vehicle, it is desirable to be able to photograph with enough accuracy to recognize the license plate and identify the vehicle. Even if the license plate information cannot be identified, it is acceptable to photograph information that can identify the vehicle, such as the make and color, but it is more preferable to have the accuracy to identify the license plate information. A night photography capability configuration can be achieved by, for example, setting the brightness of the image quality captured by the camera for nighttime use, using a high-sensitivity camera that can shoot even in low light, or using an infrared camera or a night vision camera.

[0023] (6) The housing for the camera that captures areas outside the vehicle other than the front of the vehicle may be equipped with a mounting part that attaches to the outside of the vehicle. Although privacy glass such as tinted glass may be used for glass other than the windshield, by installing it on the outside of the vehicle, the outside can be captured clearly regardless of whether or not it is privacy glass. A small rear camera that can be mounted on the outside of the vehicle is good because it can be installed on various vehicles regardless of whether or not the rear window is made of privacy glass. It is good to install it in an inconspicuous place on the outside of the vehicle so that it is less likely to be stolen. Also, for example, the camera can be made small and attached to the part of the license plate fixing bolt, for example, and it is good to make it look like a fixing bolt so that it is even less conspicuous.

[0024] It is preferable to have a function of changing shooting conditions according to the type of glass of the vehicle in the shooting range of a camera that shoots an area outside the vehicle other than the front of the vehicle when the camera is mounted in the passenger compartment of the vehicle. The camera shoots a view outside the vehicle through the glass, and by shooting under shooting conditions according to the type of glass at the time of shooting, it can be shot beautifully regardless of the direction of shooting. For example, one system can be, for example, a system for front shooting or a system for rear shooting, and can be used according to the application.

[0025] The shooting conditions are preferably such that, for example, the brightness of the image quality can be adjusted. For example, it is preferable to be able to shoot with an appropriate image quality for both the front glass using transparent glass and the rear glass using privacy glass or the like.

[0026] (8) It is provided with monitor means for outputting an image shot by a camera that shoots an area outside the vehicle other than the front of the vehicle, and the monitor means is configured separately from the housing on which the camera that shoots an area outside the vehicle other than the front of the vehicle is mounted, and is preferably installed at a position visible to the driver.

[0027] By doing so, since the image shot of the area outside the vehicle other than the front of the vehicle is output to the monitor means installed at a position visible to the driver, the driver can view the image outside the vehicle other than the front of the vehicle by looking at the monitor means. Therefore, for example, when the direction shot by the camera is the area outside the vehicle behind the vehicle, even if the vehicle originally does not have a back view monitor, the function of the back view monitor is exhibited. Also, for example, when the direction shot by the camera is the area outside the vehicle diagonally in front of the vehicle, even if the vehicle originally does not have a side view monitor, the function of the side view monitor is exhibited.

[0028] Furthermore, even in vehicles that are originally equipped with rearview monitors and / or sideview monitors, if the shooting direction and field of view of the on-board cameras for those monitors are misaligned, the monitors originally installed in the vehicle and the monitoring devices will display images of a partially or entirely different area, which is beneficial because it allows for a wider view of the situation outside the vehicle.

[0029] The separate monitoring device can be dedicated to this system, but it is preferable to use the monitoring device of another device. The monitoring device of another device could be, for example, the monitoring device of a system such as a drive recorder that records in different directions. If the system such as a drive recorder that records in different directions records in front, for example, it would be good to output the video being recorded in front to the monitoring device under normal circumstances, and then automatically switch the video output to the monitoring device to the video recorded by the rear camera when the vehicle is reversing. In this way, it can serve as a substitute for a backup camera.

[0030] Furthermore, it would be beneficial to have a function that automatically switches the video output to the monitor to footage captured by a side camera when a left / right turn or lane change is detected, for example, based on turn signal information or steering angle information. In particular, it would be good to link this switching to the vehicle's speed. For example, if the vehicle is stopped with a speed of 0 and the turn signal information indicates a right or left turn, there is a high probability that the vehicle is stopped at an intersection or similar location to make a right or left turn, so it would be good to automatically switch and output the video of the direction of the turn. This would be beneficial because it would allow the driver to check the situation in the direction of travel, even at intersections with poor visibility. Also, for example, if the vehicle is slowly moving without using a turn signal and gradually changing its lane based on steering angle information, it would be good to automatically switch to the video of a camera that captures the area outside the vehicle in the direction of the lane change. When slowly moving and gradually changing lane to the left or right, there is a high probability that the vehicle is moving closer to the curb for parking or similar purposes, so displaying the area outside the vehicle in the direction of the move on the monitor would allow for safer parking. For example, when parking a car on a narrow road, there is a desire to park as close to the left or right as possible. However, concerns about the tires falling into an open gutter or driving onto a curb on the side of the road may prevent the driver from parking close enough. With this system, the driver can check the situation in the direction they are trying to park by viewing the video feed, allowing them to park appropriately. Even drivers who lack a sense of their car's width can check the area around the front and rear tires and confirm their sense of the car's width, which is beneficial. It would be particularly useful if the system could automatically switch when parking on the opposite side of the driver's seat (for example, the left side in the case of a right-hand drive vehicle). This would allow the driver to check the blind spot on the opposite side of the driver's seat (for example, the left side in the case of a right-hand drive vehicle) on the monitor without having to manually switch settings.

[0031] Furthermore, for example, the area outside the vehicle that is captured by the camera, other than the area directly in front of the vehicle, should include the area around the vehicle's tires. In this way, it becomes a tire monitoring camera. Such a system is particularly preferable to implement in large vehicles. For example, it can be used to visually check for foreign objects (e.g., people, objects, etc.) around the tires when starting the vehicle, or to visually check for any abnormalities in tire pressure. This can be checked "visually" from the driver's seat without using equipment such as a TPMS (Tire Pressure Monitoring System).

[0032] (9) It is advisable to provide a notification means to inform people outside the vehicle that the system is in operation. This would allow, for example, people in following vehicles or people approaching the vehicle to be notified that the system is operating. For example, when driving at night, it would be possible to inform following vehicles that the vehicle is equipped with a system that records video, such as a dashcam, which would discourage following vehicles from engaging in dangerous driving such as tailgating, thus preventing such dangerous driving from occurring.

[0033] The notification method should be a light-emitting device such as an LED. This is good because it allows for a simple configuration to clearly communicate to those around that the system is in operation. The light-emitting device can be installed separately from the housing that houses the camera, but it is better to install it in the same housing as the camera. Installing it in the same housing as the camera allows people outside the vehicle to intuitively understand that the camera is in operation and taking pictures, which is a good way to communicate this.

[0034] (10) The housing for mounting the camera that photographs areas outside the vehicle other than the front of the vehicle should be mounted on the rear side of the interior of the vehicle via a ball joint bracket, and the bracket should be equipped with fixing means to fix the camera so that the orientation of the camera that photographs areas outside the vehicle other than the front of the vehicle does not change even if a biasing force is applied to the housing after positioning using the ball joint. In this way, for example, even if luggage comes into contact with the housing on which the camera is mounted when the back door is closed, the orientation of the camera will not change and the desired direction can be photographed.

[0035] Systems that do not have the aforementioned fixing means rely on ball-joint friction for posture maintenance, and if a biasing force exceeding a predetermined level is applied to the housing after positioning, the orientation of the housing and, consequently, the camera may change. Users who are not conscious of systems such as dashcams, or beginners, may not notice or even care if a biasing force is applied to the housing due to carelessness, causing the camera's orientation to change. As a result, they may drive the vehicle with the camera in that changed orientation, failing to capture the desired area and rendering the system useless.

[0036] The fixing mechanism should ideally be one that physically secures the object so that its orientation does not change. For example, using a physical lock such as a pin, which can be inserted to prevent rotation, is a simple and effective solution. A dual fixing mechanism, such as a ball joint and a separate fixing mechanism, is preferable. In particular, using frictional force with the ball joint allows the orientation of the housing and, consequently, the orientation of the camera to be aligned to the desired state, while the fixing mechanism ensures that the housing's orientation does not change physically. For example, if the solid means involves passing a fixing pin or similar component between the male and female parts that make up the ball joint, a simple physical lock can be achieved.

[0037] (11) The housing that mounts the camera that photographs areas outside the vehicle other than in front of the vehicle is preferably connected to the second housing that mounts the monitor, and the orientation of the camera that photographs areas outside the vehicle other than in front of the vehicle can be changed while the two are connected. In this way, the orientation of the camera can be changed relative to the orientation of the monitor. For example, the monitor can be installed in a position that is easy for the driver to see, and the camera can be configured to photograph in a desired direction by changing its orientation.

[0038] A configuration that allows the camera's orientation to be changed could be, for example, a configuration in which the housing rotates relative to a second housing, causing the camera to rotate along with the housing, or a configuration in which the housing is fixedly connected to the second housing, and the camera rotates as a part of the housing rotates.

[0039] If the housing that mounts the camera rotates relative to the second housing that mounts the monitor, it is advisable to provide a mechanism that maintains the angle at a predetermined rotational angle at the contact surface between the housing and the second housing. The housing may be equipped with multiple cameras, for example, two cameras, and the two cameras may be configured to rotate forward and backward within a range that allows for angle adjustment. If two cameras are provided, it is advisable to record the images captured by the two cameras simultaneously to a single recording unit.

[0040] (12) A housing that mounts a camera for photographing areas outside the vehicle other than the front of the vehicle and a main unit are rotatably connected at the center of rotation via a connecting member, and the connecting member constitutes a means for electrically connecting the camera and the equipment inside the main unit. In this way, an electrical connection can be made without using FPCs or wires, and it is less likely to break as it will not break even if it is rotated continuously. The connecting member should have an electrical connection means and a function for rotation, and for example, a pin jack can be used as it can be implemented with a simple configuration. For example, if a pin jack is used, an electrical connection can be made simply by plugging it in and it can be connected rotatably, so productivity is good. Also, for example, if a pin jack / pin plug is used as the connecting member, it is possible to directly connect the pin plug (male) and pin jack (female) provided on the housing and the main unit, respectively, to integrate the housing and the main unit, or to connect the pin plug and pin jack via a connecting cable to separate the housing and the main unit. When another camera is mounted on the main unit, if it is directly connected using the former pin jack, it becomes an integrated two-camera system.

[0041] (13) A housing that mounts a camera that captures areas outside the vehicle other than the front of the vehicle and another housing that has means for outputting to a recording unit that records the video may be connected by a general-purpose cable that transmits audio and video signals. In this way, by using a general-purpose cable, for example, the housing that mounts the camera that captures areas outside the vehicle other than the front of the vehicle can be a general-purpose product that is compatible with a general-purpose cable or a backup camera from another company. For example, by using a housing that mounts a camera compatible with 24V for trucks, etc., it can be made compatible with 24V vehicles such as trucks. The general-purpose cable may be an RCA cable, for example. Compatibility with trucks, etc. makes it a significant product for corporate use.

[0042] Furthermore, it is preferable to provide, for example, an output terminal on the aforementioned separate housing for connecting with a general-purpose cable that transmits audio and video signals. In this case, by connecting, for example, a monitoring device to the output terminal, the video captured by the camera can be output to the monitoring device while also being output to the recording unit, and the recording unit can record the video. In this case, a general-purpose product can also be used as the monitoring device, which broadens the range of equipment to be selected when configuring the system, and is preferable because the desired system configuration can be achieved by using a general-purpose product even if a dedicated product is not available.

[0043] Furthermore, in the case of a system equipped with multiple cameras that capture different directions, it is advisable to use cameras that can be added using general-purpose cables, which is beneficial as it allows for compatibility with vehicles that require additional cameras, such as those with interior or external cameras.

[0044] (14) The system includes a first mode for recording video taken while the vehicle is in operation and a second mode for recording video taken while the vehicle is parked, wherein the first mode and the second mode record with different recording settings, and it is preferable to have a function that automatically switches the recording settings when the state of the vehicle switches between operation and parking. In this way, the system can record with recording settings appropriate for each situation, whether the vehicle is in operation or parked. For example, when the vehicle is in operation, such as when driving, the video taken by the camera is output to the recording unit based on a predetermined recording setting A, and when the system switches to parking, such as when the engine is turned off, the video taken by the camera is output to the recording unit based on a recording setting B appropriate for parking. Also, when the vehicle switches from parking to operation, such as when the engine is started, the system automatically switches to recording setting A and outputs the video taken by the camera to the recording unit based on that recording setting A. In this embodiment, the first mode corresponds to the driving mode, and in this embodiment, the second mode corresponds to the parking mode and parking surveillance mode.

[0045] It would be beneficial to allow users to configure the recording settings for the first and second modes from the system's main unit, and also to allow users to change and configure the power supply time while parked, for example, from the system's main unit.

[0046] Furthermore, the system should be equipped with a motion detection function that detects moving objects in the surroundings. With a motion detection function, for example, it can detect objects such as people moving around the vehicle, so it can detect people approaching the vehicle. In particular, activating the motion detection function while parked would be beneficial, as it would detect when people or other objects approach the vehicle and trigger recording. The ON / OFF setting for this motion detection function could be done manually, but it would be better to have a function that automatically switches it ON / OFF once it has been set. For example, the automatic switching could be set to OFF when the system detects that it is ready to drive (e.g., driving or engine start) and ON when it detects that the system is parked (e.g., engine stop). This would prevent issues such as not being able to record properly when driving with the motion detection function ON, or not being able to record based on motion detection when parked with the motion detection function OFF, and would also eliminate the hassle of manual switching settings.

[0047] In a system equipped with cameras that capture images in different directions, such as the front and rear, it is preferable to have a motion detection function for each of the different directions, and it is even better to be able to set whether or not to activate the motion detection function for each camera.

[0048] (15) The system may include a first system comprising a camera that photographs an area outside the vehicle other than the front of the vehicle and a first recording unit that records the images taken by the camera, and a second system which is a device that is installed on the vehicle afterwards and comprises a camera that photographs in a different direction from the first system and a second recording unit that records the images taken by the camera.

[0049] In this way, images from different directions can be captured with each camera, and the captured images can be recorded in the first and second recording units, respectively.

[0050] The camera in the second system, which captures a different direction from the first system, may, unlike the first system, capture an area other than the "external area other than the front of the vehicle," such as the front of the vehicle or the interior of the vehicle. However, it is preferable that it captures an "external area other than the front of the vehicle," similar to the first system. This is advantageous because it allows capturing different directions of the "external area other than the front of the vehicle." The second system can consist of one camera, but it is preferable to have multiple cameras.

[0051] The power supply to the first and second systems can be provided separately, but it is preferable to use a two-way splitter structure, for example, by using a direct power connection cord to supply power to both the first and second systems simultaneously.

[0052] Furthermore, if, for example, the first and / or second systems are installed at the rear of the vehicle and power is supplied from the vehicle's battery, the battery is usually located at the front of the vehicle. This necessitates wiring from the front to the rear of the vehicle, resulting in very high installation costs. In some vehicle models, power and accessories can be obtained from the trunk, so it is advisable to supply power to the rear-mounted systems from the power source located in the trunk. This eliminates the need for wiring from the front to the rear, which is beneficial.

[0053] (16) It is preferable to have a function that displays the video captured by the first system and the video captured by the second system on the same monitor simultaneously. In this way, it is possible to compare videos from different directions that were captured at the same time on the same screen.

[0054] Displaying the same information simultaneously is best done when playing back recorded video, and even better in real time. For example, when playing back recorded video, if there is a chain reaction accident, it is good to be able to check whether it was caused by your vehicle or if you were rear-ended. When done in real time, it is preferable to be able to view video from different directions and drive while being aware of the surrounding situation. In particular, even if the vehicle does not have an onboard camera to record the surroundings, it is possible to implement a function to record the surroundings aftermarket, which is good because you can drive while checking the safety of your surroundings, for example when reversing the vehicle, changing direction, or driving on a road with poor visibility.

[0055] The monitor may be, for example, a monitor provided in either the first system or the second system, but it is preferable to use a monitor from another device such as a smartphone. Using another device such as a smartphone is preferable because it can be placed within the user's reach, such as a driver, allowing for close viewing and the use of a larger screen size. The connection between the first system and / or the second system and the monitor may be a wired connection, but a wireless connection is more preferable, and in the case of a wireless connection, using Wi-Fi is even more preferable.

[0056] (17) The first system and the second system, which are installed in different locations on the vehicle, should be able to communicate with each other, and the other system should output video footage it has captured to the recording unit based on the operating status of the other system. The first system and the second system should output video footage to the recording means more reliably when a situation requiring recording occurs.

[0057] For example, the operating status of one of the two systems, the first system and the second system, could be positive, such as "the first system outputs a trigger," or negative, such as "the video being captured by the first system disappears."

[0058] For example, the first and second systems should be configured to record events triggered by an impact exceeding a certain level, and the trigger sensitivity should be adjustable. For instance, if the impact on the vehicle is weak and only one system detects the impact, the other system would not be able to record the event associated with the impact if each system were operating independently. However, the other system can record upon receiving a trigger from the other system. Furthermore, they should exchange and monitor video signals with each other, and if the video from one system suddenly stops, it should be used as a trigger to record, even if no impact is detected. If the video suddenly stops, it may indicate an abnormal situation, so it is good to use this as an opportunity to record with the other system. By coordinating triggers between the first and second systems, which are located in different places, it is possible to more reliably record when necessary.

[0059] When connecting the first and second systems, a wired connection can be used, but a wireless connection is preferable. A wireless connection eliminates the need for wiring, similar to the power supply mentioned above, making installation in the vehicle easier and cheaper, and allowing for a neater fit inside the vehicle. For wireless connections, a Wi-Fi connection is recommended.

[0060] (18) It is preferable that the first system and the second system be configured to simultaneously perform recording processing in the corresponding first recording unit and second recording unit based on triggers from terminals that can communicate with the first system and the second system, respectively. In this way, when an event occurs, the first system and the second system each record video in response to a trigger from the terminal, so that video from different directions at the time the event occurs can be recorded.

[0061] The terminal should ideally be a smartphone, and triggers from the smartphone should be generated based on the output of sensors such as a G-sensor, gyroscope, and GPS implemented in the smartphone. The smartphone should have an app installed that allows configuration of which sensors trigger which systems when certain conditions are met. Ideally, the trigger conditions should allow for combinations of multiple sensors. Furthermore, triggers from the smartphone should be based on communication. Communication-based triggers could include situations such as when a predetermined pattern occurs in IFTTT, when a phone call is received, or when certain conditions are met based on information on the web (e.g., when the current temperature exceeds 35 degrees Celsius). The app should allow for the attachment of arbitrary tags (preferably multiple tags) to the triggers, and the tag information should also be associated with the trigger and sent to the system. The system should then start event recording based on the trigger, and record the video footage in association with the received tags.

[0062] (19) In the case of a system installed on the rear side of a vehicle, such as the rear window, it is preferable to include a touch panel LCD. This is advantageous because various settings and commands can be operated by touching the touch panel LCD. For example, if the system is installed on the rear side of a vehicle, such as the rear window, there may be no interior lighting installed in the vehicle, and the system may be installed in darkness, for example, at night. Even in such cases, since a touch panel LCD is used, a certain level of brightness can be ensured, and settings can be made by touching the desired location.

[0063] While incorporating a touchscreen LCD increases the overall size of the system, potentially obstructing the driver's view of the rear, owners of foreign cars, for example, tend to prefer a larger appearance. Therefore, this is particularly suitable for systems like dashcams intended for installation in foreign cars. Furthermore, the touchscreen LCD monitor ensures a certain size, making it easier for drivers of following vehicles to recognize its presence. Thus, regardless of whether external notification methods such as indicator lights are installed, it achieves a similar effect to applying a warning sticker such as "Dashcam Installed / Dashcam Operating."

[0064] Furthermore, a 360-degree drive recorder such as the Q-01, one of the applicant's products, has the function of capturing a 720-degree range, which is a 360-degree range horizontally and a 360-degree range vertically, when installed. When such a 360-degree drive recorder is mounted on the windshield, for example, the camera's shooting area is limited to the front of the vehicle and the interior of the vehicle. This is good for checking the rear of the interior, but there are limitations in recording following vehicles. Therefore, it would be good to make a 360-degree drive recorder that can also shoot the rear of the interior compatible with a rear camera. By installing a rear camera on the rear window, etc., and shooting the area behind the vehicle outside, following vehicles can be recorded, and the above problem is solved.

[0065] Furthermore, it would be beneficial to include the ability to connect additional cameras to various types of dashcams, not just 360-degree dashcams. This would allow the dashcam to capture and record areas different from those captured by the camera built into the main unit. Dashcams should ideally have the ability to record in two or more channels and include a connection port for additional cameras.

[0066] In a system with multiple units equipped with cameras, the units may be connected using a wired method, but a wireless communication method is more preferable. For example, using a wireless LAN for connection is preferable because it eliminates the need for wiring. For example, if the units are positioned relatively far apart, such as one unit being located at the front of the vehicle interior on the windshield or dashboard and another unit being located at the rear of the vehicle, then using a wireless LAN is a good option. The multiple units may be drive recorders, each equipped with a control unit and output function to a recording unit, or camera units, where one unit has a control unit and the operation of the other units is controlled by that control unit.

[0067] For example, in vehicles that frequently travel during the day and are at risk of being involved in accidents, such as taxis, installing a dashcam that records the outside of the vehicle allows the recorded footage to be used as evidence in the event of an accident. Connecting an additional camera capable of recording the interior or rear of the vehicle to such a dashcam is beneficial, as it allows for recording interactions with passengers and the area behind the vehicle. For example, when recording the interior, the dashcam and additional camera should be mounted, for instance, near the upper center of the windshield, in the front center of the ceiling inside the vehicle, or on the rearview mirror, and configured to record from the side of the rearview mirror.

[0068] It is preferable that the device, which is installed on the vehicle afterward, has the function of acquiring and hacking video footage captured by the vehicle's onboard camera. A device equipped with such function can utilize the video footage captured by the onboard camera.

[0069] The device should ideally include a means for outputting video acquired by an in-vehicle camera mounted on the vehicle to a recording unit that records the acquired video. In this way, it can function as a device that records external video, such as a dashcam, without the need for a separate camera.

[0070] Furthermore, it would be beneficial for devices installed later in a vehicle, such as a dashcam with a camera, to have a function to acquire video footage captured by the vehicle's onboard camera. This is preferable because it allows the acquisition of video footage from an onboard camera that captures a different area than the installed camera, eliminating the need to separately prepare additional cameras or other optional accessories and the associated wiring.

[0071] The in-car camera to connect should ideally be a backup camera that captures the area behind the vehicle, such as a rearview monitor. While a backup camera cannot capture distant objects behind the vehicle because it is angled downwards, it can adequately capture approaching vehicles (for example, in the event of tailgating or a rear-end collision).

[0072] For example, in the case of a system such as a dashcam, if its external shape is not rectangular, it would be good to create a collaborative product with a character that suits that external shape. For example, devices and products such as 360-degree dashcams have the problem that the lens facing inward is conspicuous and makes passengers aware that they are being filmed, and the spherical shape of the lens part is conspicuous and may give a clunky impression. For example, as mentioned above, if a system with an external shape that is not rectangular in part or entirely is created as a collaborative product with a character that suits that external shape, the above impression can be softened, making the product easier for users to use and implement, and thus solving the above problem. For example, in the case of a 360-degree dashcam, where the camera part has a spherical external shape, it would be good to use characters such as "Medama Oyaji (Kitaro)", "Mike Wazowski (Monsters, Inc.)", or balls used in ball games (soccer, basketball, golf, baseball, etc.), and it would be good to create a collaborative product in which the spherical part of the camera part is shaped to resemble the character.

[0073] If an SD card is used as the recording unit for the video captured by the camera, it would be beneficial to include an SD alert function in the system. For example, if the SD card is not formatted for a long period of time, a large number of bad sectors may accumulate, which can cause problems with event recording by the G-sensor, preventing recording. Therefore, it would be good to configure the system to alert when a certain period of time has elapsed. For example, even if the instruction manual states that it is preferable to format the SD card every 1-2 weeks, the frequency of use differs between people who use it for commuting or work and those who are Sunday drivers, so there is little need to format it at the same time for everyone, and the timing of when a large number of bad sectors occur will also differ. Therefore, it would be good to use usage time as a criterion and issue an alert prompting formatting when the usage time reaches a set threshold. Automatic formatting would cause problems such as the deletion of video that the user has recorded without their knowledge, so it is better to issue an alert prompting formatting rather than automatic formatting. Usage time can be determined based on, for example, recording time or GPS logs.

[0074] A viewer for a system comprising a camera that photographs an area outside the vehicle other than the front, system A that outputs the image captured by the camera to a recording unit, and a device that is installed on the vehicle afterwards, a camera that photographs in a different direction from system A, and system B that outputs the image captured by this camera to a recording unit, preferably having a function to display the mounting positions of systems A and B, for example, the mounting positions of the cameras in each system.

[0075] This viewer should ideally include, for example, an editing mode and a viewing mode. In editing mode, for example, a car diagram or shape should be displayed, and clicking on the location where a camera is placed within that diagram should draw a frame around the camera's location. The drawn frame should be color-coded to indicate which camera it represents. In viewing mode, the viewer should have a function to play and display video captured by one or more designated cameras, and when playback is performed, the frame of the triggered camera should be displayed in a conspicuous manner, such as blinking. The frame color should be the same as the frame color of the graph or playback screen.

[0076] The mounting location can be indicated, for example, by displaying a top-down view of the car on the viewer, and marking the area on the car's shape corresponding to the camera's mounting position in a way that clearly indicates it is the camera's location. This makes it easy to see where the camera is installed. For example, the approximate area being captured by the camera can also be understood from its mounting position.

[0077] To indicate the camera's position, for example, a designated shape or icon should be displayed at the corresponding location. The viewer can be implemented using various methods such as a PC viewer, web viewer, or application.

[0078] The inventions described in (1) to (19) above can be combined in any way. For example, one may combine all or part of the configuration of the invention shown in (1) with at least part of the configuration of at least one of the inventions from (2) onward. In particular, it is preferable to combine the invention shown in (1) with at least part of the configuration of at least one of the inventions from (2) onward. The applicant intends to obtain patent rights, design rights, etc., for those including these configurations through amendment, divisional application, change application to design registration application, etc. [Effects of the Invention]

[0079] For example, areas outside the vehicle other than the front can be filmed, resulting in a wider and more sufficient range of recorded video.

The applicant intends to obtain rights to such components through divisional applications, amendments, etc. For example, sections in this specification that state "can do" are descriptions that clearly indicate the effects that can be achieved, and there are also components that demonstrate effects even without such descriptions. Furthermore, there are effects that can be grasped by the configuration even without such descriptions. [Brief explanation of the drawing]

[0081] Embodiments of the present invention will be described below with reference to the drawings. These drawings are used to illustrate the technical features that the present invention may adopt. The configuration and shape of the described apparatus are merely illustrative examples, and the present invention is not to be construed as being limited thereto. Various changes, modifications, and improvements can be made based on the knowledge of those skilled in the art, without departing from the scope of the present invention.

[0082] [Basic configuration of a dashcam] Figure 1 shows a drive recorder, a vehicle-mountable device that is a suitable embodiment of the system comprising the present invention. This drive recorder 1 is not a vehicle-mounted device or equipment installed in the vehicle, for example, at the time of shipment from the vehicle manufacturer's factory or purchase from a vehicle dealer, but rather a device that is installed on the vehicle 2 afterward. This drive recorder 1 comprises, for example, a drive recorder body 4 that implements a predetermined function, and this drive recorder body 4 is attached to the vehicle 2, for example, the rear window 3, using a predetermined bracket 5.

[0083] The drive recorder unit 4 has a flat rectangular case body 10, and the camera 11, first LED 12, second LED 13, control unit 14, card slot 15, microphone 16, anomaly detection sensor 17, power supply unit 18, etc. are mounted on the case body 10.

[0084] The case body 10 has a flat rectangular shape and is held in an upright, suspended position via the bracket 5. Since the drive recorder body 4 of this embodiment does not have a monitor, the case body 10 can be made smaller accordingly.

[0085] Bracket 5 has a connecting member at one end that connects to the top surface of the case body 10, and a mounting surface at the other end that is attached to the rear glass 3. The mounting surface is equipped with a fastener such as double-sided adhesive tape or an adhesive sheet, and is attached and fixed to a predetermined position on the rear glass 3 using this fastener. Bracket 5 also has a connecting part in its middle section that allows for adjustment of angle and orientation, such as a ball joint, and has the function of changing and adjusting the orientation and position of the case body 10, as well as fixing it in the desired position.

[0086] The shooting range of camera 11, when mounted on vehicle 2 using bracket 5, is set to include the area behind the vehicle, which is one of the areas outside the vehicle other than the front of the vehicle. More preferably, the optical axis and field of view direction of the lens of camera 11 should be set to point directly behind vehicle 2. The angle of view of camera 11 should be a predetermined angle of 180 degrees or less, and more preferably an obtuse angle to shoot in a wide-angle range. When the drive recorder unit 4 is installed in the desired position as described above, it is best to ensure that the area in front of the vehicle is not included in the shooting range with respect to camera 11.

[0087] Camera 11 should be capable of nighttime shooting when the vehicle's lights are not illuminating the area. The camera's shooting range is the area behind the vehicle that is not illuminated by the vehicle's lights. By using a nighttime-capable camera 11, it is possible to take bright and clear pictures even at night. As a nighttime-capable camera 11, it is good to use a high-sensitivity camera capable of shooting in low light conditions using STARVIS (registered trademark), an infrared camera, or a night vision camera. For example, it is good to have different shooting modes based on ambient brightness, such as a daytime shooting mode and a nighttime shooting mode, and to have a function to switch between them by setting. The switching function may be performed manually, for example, but it is good to have a function that switches automatically based on ambient brightness, time information, etc.

[0088] When using special cameras such as infrared cameras and night vision cameras for nighttime shooting, it is possible to prepare a separate camera for daytime shooting and switch between them. However, it is better to use a camera that can shoot both day and night using a high-sensitivity camera capable of shooting even in low light, or a camera with a function to switch the brightness of the image quality captured by the camera between daytime and nighttime, as this allows one camera to be used regardless of the time of day.

[0089] The rear window 3 is often made of privacy glass such as tinted glass. The night-time camera 11 is good because it can penetrate this privacy glass and take clear pictures.

[0090] The camera 11 can have high resolution, but it is best to keep it to around 1 to 2 million pixels. By limiting the pixel count to this level, the camera 11 and, consequently, the drive recorder unit 4 can be made smaller.

[0091] The first LED 12 is positioned on a predetermined surface of the case body 10 where the camera 11 is not installed. The surface on which it is installed should be the surface facing the interior of the vehicle when the drive recorder body 4 is mounted on the vehicle 2, and preferably the rear surface, that is, the surface opposite to the surface on which the camera 11 is installed. This opposite surface is the surface that the driver faces when they visually check the area behind the vehicle, for example, through the vehicle's rearview mirror or by directly turning their head to look behind them, and is therefore easily visible to the driver.

[0092] The first LED 12 constitutes a notification means for informing people inside the vehicle, such as the driver, that the device is in operation. This first LED 12 is configured to light up when the drive recorder unit 4 is operating. The control unit 14 controls the lighting of this LED. Since the first LED 12 lights up when the device is in operation, users inside the vehicle, such as the driver, can confirm that the device is in operation even without a monitor, which is advantageous. In particular, by using a light-emitting element such as an LED, the user can confirm that the device is in operation at an appropriate time, which is advantageous.

[0093] The lights can be illuminated in various ways, such as continuously or flashing, but continuous illumination is preferable. Flashing is conspicuous and can be annoying to drivers, but continuous illumination avoids this problem, making it ideal.

[0094] The second LED 13 is positioned on the side of the case body 10 where the camera 11 is installed (for example, the front). This second LED 13 constitutes a notification means that informs people outside the vehicle that the drive recorder unit 4 is in operation. The second LED 13 operates to light up when the drive recorder unit 4 is in operation. The control unit 14 controls the lighting of this LED.

[0095] The microphone 16 collects sounds from the surrounding area of ​​the drive recorder unit 4. When the drive recorder unit 4 is mounted on the rear window 3, the microphone 16 collects sounds such as the voices of people inside the car and other sounds occurring inside the car, as well as impact sounds when an object collides with the vehicle 2.

[0096] The card slot 15 is a device that allows for the insertion and removal of memory cards 19, such as microSD cards and SD cards, and performs data reading and writing operations on the inserted memory card 19. For example, it records video captured by the camera 11 and sound collected by the microphone 16 onto the memory card 19 according to instructions from the control unit 14.

[0097] The anomaly detection sensor 17 is, for example, an acceleration sensor or a 6-axis sensor, and detects the state of the vehicle, such as the impact applied to the vehicle 2, the vehicle's acceleration, and its tilt. The anomaly detection sensor 17 is not limited to the examples given above, but may also be, for example, a proximity sensor that detects the approach of an object, or a sensor that detects various events that trigger the recording of video.

[0098] The power supply unit 18 has the function of supplying power voltage to devices such as those included in the drive recorder unit 4 and operating them. The power supply unit 18 has, for example, a jack 18a on the case body 10 for detachably attaching the adapter terminal of a power adapter that can be connected to a battery mounted in a vehicle (not shown), and a predetermined power supply circuit is electrically connected to the jack 18a. The power supply circuit is built into the case body 10 and supplies a power supply voltage of a desired voltage value to each device. As a result, the drive recorder unit 4 operates by receiving power from the battery of the vehicle 2.

[0099] The control unit 14 is a microcontroller equipped with a CPU, ROM, RAM, non-volatile memory, I / O, etc., and is connected to the above-mentioned parts as shown in Figure 1(e). The control unit 14 controls the operation of output devices (first LED 12, second LED 13, card slot 15, etc.) based on information input from the above-mentioned various input devices (camera 11, microphone 16, anomaly detection sensor 17, etc.) and outputs predetermined information.

[0100] The functions of the drive recorder unit 4 in this embodiment are realized by, for example, storing the firmware, which is executed by the CPU in the control unit 14, in the NANDFlash memory of the control unit 14, and then executing it. The firmware stored in the NANDFlash memory can be updated by new firmware stored in the memory card 19.

[0101] The control unit 14 records, for example, video data captured by the camera 11 and audio data collected by the microphone 16. This recording is performed continuously, for example, while the vehicle 2 is running and in a drivable state. When an event condition is met, it records video and audio for a certain period before and after the event as separate data. Both the continuously recorded data and the separate data for events are recorded on the memory card 19. When continuous recording is not performed, the control unit 14 of the drive recorder normally temporarily records video and audio for a certain period in a buffer memory, etc., and when an event condition is met, it uses the temporarily recorded data, etc., to record video and audio for a certain period before and after the event on the memory card 19.

[0102] Furthermore, when vehicle 2 is parked with the engine turned off, it operates in parking surveillance mode and records video data captured by camera 11 and other data to memory card 19 according to the set operating conditions. The set operating conditions could, for example, be to record images taken at predetermined time intervals, or to continuously record video data for a predetermined time when an abnormality is detected by the abnormality detection sensor 17.

[0103] The control unit 14 should control the first LED 12 to light up continuously when a predetermined device is operating normally, such as when the camera 11 starts recording. The control unit 14 should also control the second LED 13 to blink when a predetermined device is operating normally, such as when the camera 11 starts recording. The conditions for continuously lighting the first LED 12 and blinking the second LED 13 can be the same, but it is better if they are different, and if they are different, it is better to loosen the conditions for the second LED 13. The first LED 12, which notifies the driver, etc., lights up when the drive recorder unit 4 is operating normally, but it is good to make the second LED 13 blink even if it is not operating normally, so that it can deter people regardless of whether it is operating or not.

[0104] According to the embodiment described above, even in vehicles that do not originally have an in-vehicle device for shooting and recording the rear view, images of the scenery behind the vehicle, following vehicles, etc., can be recorded on the memory card 19. The recorded video data can be viewed by the user by, for example, removing the memory card 19, inserting it into a card reader connected to a PC, and displaying it on a monitor using a viewer installed on the PC.

[0105] Since the drive recorder 1 of this embodiment is used mounted on the rear window 3, the camera 11's field of view does not include, for example, the driver or passengers inside the vehicle, and instead captures a large view of the scenery behind the vehicle. Therefore, even if the resolution of the camera 11 is somewhat low, the video data captured by the camera 11 will clearly show, for example, following vehicles and their license plates. For example, if a collision occurs from behind, the collision can be recorded. Furthermore, the resolution of the camera 11 should be set to a level where license plate numbers can be deciphered and the make and model of following vehicles can be recognized.

[0106] In this embodiment, the case body 10 does not have a monitoring means, so for example, the driver cannot directly check whether the camera 11 is operating by looking at the monitoring means. In this embodiment, for example, when a predetermined device is operating normally, such as when the camera 11 starts recording, the first LED 12 lights up continuously, so for example, the driver can check that the drive recorder body 4 is operating normally by checking that the first LED 12 is lit, which is good. In particular, in this embodiment, the first LED 12 is placed on the surface opposite to the surface on which the camera 11 is installed, so for example, when the driver checks the rear of the vehicle using their eyes, either through the rearview mirror of the vehicle or by directly turning around to check the rear of the vehicle, it naturally comes into the driver's field of view and they can easily check that it is operating. In this way, without a monitor, it is unclear whether it is operating or not, which can cause anxiety for the user, but this anxiety can be alleviated by providing a notification means that notifies people inside the vehicle that it is operating.

[0107] The second LED 13 lights up when the system is in operation, so it can notify people in following vehicles or people approaching the vehicle that the system is working. In particular, because it uses light-emitting elements such as LEDs, it is good that it can clearly communicate to those around that the system is in operation with a simple configuration.

[0108] In particular, at night, the illumination of the second LED 13 is conspicuous, so it can be used to signal to drivers of following vehicles, for example, that a system that records video, such as a dashcam, is installed, thereby discouraging drivers of following vehicles from engaging in dangerous driving such as tailgating, and thus preventing such dangerous driving from occurring. In this embodiment, since the camera 11 is mounted in the same housing as the case body 10, it is possible to make it intuitively clear to people outside the vehicle that the camera 11 is in operation and recording, which is advantageous.

[0109] The second LED 13 may be provided separately from the case body 10 on which the camera 11 is mounted, for example, but it is better to provide it on the case body 10 on which the camera 11 is mounted, as in this embodiment. By providing it on the same case body 10 as the camera 11, it is possible to make it intuitively clear to people outside the vehicle that the camera 11 is operating and taking pictures, which is good for attracting attention.

[0110] The operation of the first LED 12 and / or the second LED 13 may be configured to occur in conjunction with the power ON / OFF, rather than being controlled by the control unit 14. However, as in the embodiment described above, it is more preferable for the control unit 14 to control the operation of a predetermined device in the drive recorder main unit 4.

[0111] (A variation of the notification method for people inside the vehicle) In the embodiment described above, the first LED 12 was used as a means of providing information to people inside the vehicle, but other light-emitting elements may also be used, such as a speaker that outputs sound. Using a light-emitting element such as an LED, as in the embodiment, is advantageous because it allows for confirmation at appropriate timings.

[0112] In the embodiment described above, the notification means may be provided separately from the case body 10 on which the camera 11 is mounted, but it is preferable to provide it in the same case body 10 as in the embodiment. Providing it in the same case body is advantageous because it allows for an intuitive understanding that the drive recorder unit 4 is operating normally.

[0113] (Danger warning function) Figure 2 shows another embodiment in which a hazard warning function is added to the basic configuration shown in Figure 1 described above. In this embodiment, the drive recorder main unit 4 is equipped with, for example, a warning unit 20, and the control unit 14 is equipped with a function to detect hazards based on the video captured by the camera 11 and output to the warning unit 20. In this way, the driver is looking ahead while driving and cannot pay attention to or check what is happening outside the vehicle other than in front of them, but since the driver is warned of hazards occurring in directions other than in front, the driver can take action to avoid those hazards.

[0114] If the camera 11's shooting range is set to the rear of the vehicle, as in the embodiment described above, then, for example, the control unit 14 will output an alert from the notification unit 20 when it detects, for example, an approaching vehicle based on the captured video data.

[0115] The notification unit 20 may be, for example, a speaker. Using a speaker allows for a reduction in the size of the case body 10 compared to using a display function such as a monitor, while still being implemented within the same case body 10. When the notification unit 20 is a speaker, the control unit 14 controls the notification unit 20 to output an alert using voice, such as "Vehicle approaching," or an alarm sound such as a "beep," when it detects the approach of a following vehicle.

[0116] The control unit 14's detection of approaching vehicles, such as a following vehicle, based on the video footage captured by the camera 11, can be performed, for example, based on the size of the following vehicle within the captured video footage. For instance, approaching vehicles can be detected when the area or dimensions of the following vehicle within the captured video data exceed a set value. This approach is advantageous because it eliminates the need to install a separate sensor for detecting approaching vehicles.

[0117] This approach is beneficial because, while a driver cannot constantly keep their eyes on the rear while driving, if they are alerted to an approaching vehicle while looking ahead, they can use the rearview mirror or other means to check the situation behind them. Audio alerts are particularly good because they can be recognized regardless of which direction the driver is looking.

[0118] (A variation of the proximity warning alert function) The detection of approaching vehicles by the control unit 14 should be replaced with, or in addition to, the detection performed when the size of the following vehicle exceeds a set value, by the control unit 14, for example, by providing a function to detect rapid approach based on the magnification rate per unit time of the following vehicle in the captured video data. When used in conjunction with the size-based approach detection function, if rapid approach is detected, it is preferable to issue a more urgent warning that differs from the normal size-based approach warning.

[0119] The drive recorder unit 4 may, for example, be equipped with a sensor to measure the distance to a following vehicle, and the control unit 14 may have a function to detect a vehicle approaching from behind based on the distance to the following vehicle. This is preferable because it allows for more accurate detection of approaching vehicles. The proximity warning based on the distance between vehicles may, for example, be set to a reference distance and notify the driver when the distance to the following vehicle approaches or falls below the reference distance.

[0120] (Approach warning alert function that takes into account the vehicle's speed) The proximity-based alerts in the embodiments and modifications described above should preferably include a function to control the warning operation based on the vehicle's speed. For example, the control unit 14 may issue a normal proximity warning alert when the vehicle's speed is equal to or greater than a reference speed, and may either not issue a proximity warning or issue a mild proximity warning when the vehicle does not reach a certain speed.

[0121] With this setup, for example, if an alert sounds every time a vehicle approaches while stopped at a traffic jam, intersection, or traffic light, it can become cumbersome and annoying. However, in this configuration, if the vehicle is below a certain speed, the proximity warning alert will not be issued, or if it is issued, it will be a mild alert. Therefore, the normal proximity warning alert will not be issued when the vehicle is stopped, slowing down to stop, or traveling at a low speed due to traffic congestion. For example, it would be good to set it so that an alert is triggered when a vehicle approaches within 20m while the vehicle is traveling at a speed of 40km / h or more. Furthermore, it would be good to have a highway mode that only sounds an alert when the vehicle is traveling at a speed of 70km / h or more, and allow users to switch between this and a general mode that sounds an alert when the vehicle is traveling at a speed of 40km / h or more. This would be good because it would accommodate users who only want to be alerted on highways and not on general roads.

[0122] When proximity detection includes a function to determine the distance between vehicles and compare it to a reference distance, it is preferable to set multiple reference distances according to the vehicle's speed. For example, the reference distance should be longer as the vehicle's speed increases. In this way, for example, by setting a reference distance for the speed corresponding to driving on a highway that is longer than the reference distance for the speed corresponding to driving on a general road, it is possible to receive notification even when the distance to the following vehicle is relatively large when driving on a highway compared to when driving on a general road.

[0123] Another configuration for multiple installations is to set the reference distance for when the vehicle speed is 0 or low to be shorter than the reference distance for when the vehicle is traveling at normal speeds. This allows the system to either not notify or only give a mild warning when the distance to the following vehicle decreases while the vehicle is stopped, for example, in traffic jams, at intersections, or waiting at traffic lights, but to issue a proximity warning when the vehicle gets close enough to pose a collision risk.

[0124] (A variation of the detected danger: aggressive driving) Furthermore, the danger to be detected may be, for example, aggressive driving by surrounding vehicles. The control unit 14 extracts a following vehicle based on the video data captured by the camera 11, analyzes the driving pattern of the extracted following vehicle, and outputs an aggressive driving warning alert if it matches the set aggressive driving pattern. The set aggressive driving pattern may be, for example, a driving style that involves suddenly approaching and then swerving from side to side after getting close. Also, if a sensor for detecting the distance to the following vehicle is provided, the control unit 14 may output an aggressive driving warning alert if, for example, the change in the distance between vehicles exceeds a set value.

[0125] (A function that records vehicles following dangerous driving.) In addition to the aforementioned danger warning alert function, or as an alternative to the alert function, it would be beneficial to include a function that saves still images or videos to a dedicated folder, for example, when a vehicle approaches rapidly. The system should be configured so that users can later review the license plate number of the vehicle that was driving aggressively by playing back the saved images or videos.

[0126] (A variation of the warning message) The control unit 14 should preferably have a function to detect approach to moving objects, such as a child running out into the road, or to fixed objects, and to notify the driver of the risk of collision. With such a function, for example, when reversing the vehicle, the control unit can notify and alert the driver of approaching a child running out into the road or various fixed objects, giving the driver an opportunity to, for example, apply the brakes and check behind them again, thus avoiding collisions or contact accidents. For example, even in vehicles that are not equipped with sensors that detect approach to obstacles such as people or objects, such as corner sensors or backup sensors, it is possible to detect and notify the driver of approach to such obstacles.

[0127] (Torture by Hochi Shimbun) In the embodiments and modifications described above, the notification unit 20 outputs sound from a speaker or the like, but it may also be based on visual information, such as a monitor. However, as mentioned above, using sound is more preferable. Notification using sound is advantageous because, for example, the driver can be aware of the notification even when they are looking ahead and not looking at a display or monitor.

[0128] When using a monitor, it is preferable to configure it separately from the case body 10 on which the camera 11 is mounted and to position it in a location visible to the driver while driving. A suitable location for the driver to see it is, for example, on the dashboard. The case body 10 is equipped with a communication unit, which is a communication interface for wired and / or wireless communication, and is connected to the separate monitor for data communication. In this embodiment, the case body 10, which mounts the camera 11, control unit 14, and communication unit, etc., is mounted on the rear window 3 at the rear of the vehicle 2, and the monitor is positioned at the front of the vehicle 2. Therefore, the communication connection between the communication unit mounted on the case body 10 and the monitor may be a wired connection, but a wireless connection is more preferable, and in the case of a wireless connection, using wireless LAN or Wi-Fi is even more preferable.

[0129] Hazard warning alerts using a monitor can be, for example, notifications consisting of text, graphics, or other patterns, but it is better to display them along with the video being recorded. In this way, following vehicles that are driving aggressively or approaching too closely will be displayed on the monitor, allowing the driver to check the situation of the following vehicle that is driving dangerously.

[0130] A dedicated monitor is acceptable, but it is preferable to utilize the monitoring capabilities of another device. If there is already a monitor for another device, installing a separate dedicated monitor would result in multiple monitors, which could be cumbersome and make it difficult to quickly determine which monitor to use. Therefore, using the monitoring capabilities of another device solves these problems.

[0131] (A configuration without a recording unit) It is preferable not to install the recording unit in the case body 10 where the camera 11 is mounted. This would allow for further miniaturization of the case body 10, which would be beneficial as it would not obstruct the driver's view.

[0132] If the recording unit is not implemented in the case body 10, the recording unit may be implemented in a separate enclosure from the case body 10 and placed in a vehicle or the like, but it is better to use the cloud.

[0133] (An embodiment equipped with monitoring means) As shown in Figure 3, the drive recorder of this embodiment includes a monitor device 21 that outputs video captured by the camera 11. The monitor device 21 is configured separately from the drive recorder main unit 4 and is preferably installed in a location visible to the driver, such as on the dashboard of the vehicle 2. The drive recorder main unit 4 and the monitor device 21 are connected by a predetermined communication method. The predetermined communication method can be a wired communication method or a wireless communication method, and a wireless communication method is more preferable.

[0134] In this configuration, the control unit 14 outputs the video footage of the area behind the vehicle to the monitor device 21, which is installed in a position visible to the driver. As a result, the driver can view the video footage of the area behind the vehicle by looking at the monitor device 21. Therefore, even in vehicles that do not originally have a rearview monitor, the function of a rearview monitor can be achieved. Furthermore, even in vehicles that originally have a rearview monitor, if there are areas where the shooting direction and field of view of the on-board camera for the rearview monitor differ from the shooting direction and field of view of the camera 11 of the drive recorder unit 4, the rearview monitor originally installed in the vehicle and the monitor device 21 will display video footage of some or all of the different areas, which is beneficial because it allows the driver to see a wider range of the situation outside the vehicle.

[0135] Furthermore, the video data of the area behind the vehicle captured by camera 11 may be output to the monitor device 21 at all times, but it is preferable to display it only when the display conditions are met. The display conditions could be, for example, when the vehicle's reverse signal is input. In this way, the video of the area behind the vehicle will be displayed on the monitor device 21 when the vehicle is moving in reverse, which is advantageous. It is also preferable to display the video when an alert is needed, as mentioned above.

[0136] The monitor device 21, which is separate from the drive recorder unit 4, may be a dedicated unit, but it is preferable to use a monitor from another device. The monitor from another device may be, for example, a monitor for a drive recorder or other system that records in a different direction. If the monitor is, for example, a monitor for a drive recorder that records in front, it is preferable that it has a function that normally outputs the video being recorded in front to the monitor, and when the vehicle reverses, the video output to the monitor is automatically switched to the video recorded by the rear camera by inputting the vehicle's reverse signal.

[0137] (Another embodiment equipped with monitoring means) Figure 4 shows another embodiment of a drive recorder equipped with a monitor device 21 that outputs video captured by the camera 11. In this embodiment, the monitor device 21 is mounted on the case body 10 on which the camera 11 is mounted. The monitor device 21 is positioned on the side opposite to the mounting surface of the camera 11, and when the drive recorder body 4 is installed in a predetermined position at the rear of the vehicle interior, the monitor device 21 faces forward into the vehicle interior.

[0138] In this way, when installing the drive recorder unit 4 in a predetermined location, such as the rear window 3 of a vehicle, it is possible to do so while the video captured by the camera 11 is output to the monitor device 21, allowing the orientation of the case unit 10 and, consequently, the shooting range of the camera 11 to be checked by looking at the monitor device 21, which is advantageous.

[0139] If the case body 10 that houses the camera 11 is equipped with a monitor device 21, the case body 10 becomes larger. For example, owners of foreign cars tend to prefer a relatively large appearance, so this is particularly suitable for drive recorders intended for installation in foreign cars. Also, by equipping the case body 10 with a monitor device 21, a certain size is ensured, making it easier for drivers of following vehicles to recognize its presence. Therefore, regardless of whether or not external notification means such as a second LED 13 are installed, it has the same effect as attaching a warning sticker such as "Drive Recorder Installed / Drive Recorder Operating," which is beneficial.

[0140] Furthermore, the aforementioned monitoring device 21 may be equipped with, for example, a touch panel LCD. This would allow various settings and commands to be operated by touching the touch panel LCD. For example, if the drive recorder 1 is installed on the rear side of the vehicle, such as the rear window 3, there may be no interior lights installed in the vehicle, and the system may be installed in darkness, for example, at night. Even in such cases, since a touch panel LCD is used, a certain level of brightness can be ensured, and settings can be adjusted by touching the desired location, which is advantageous.

[0141] (Ceiling-mounted type) Figure 5 shows another embodiment. The drive recorder in this embodiment records the area behind the vehicle 2, and the case body 10 that houses the camera 11 for recording the area behind the vehicle is configured to be attached to the ceiling 6 of the vehicle interior on the rear window side of the vehicle via a bracket 5 which has a mounting part for being attached to the ceiling 6 of the vehicle interior.

[0142] Bracket 5 has a connecting member at one end that connects to the top surface of the case body 10, and a mounting surface at the other end that is fixed to the ceiling 6. The mounting surface is equipped with a fastener such as double-sided adhesive tape or an adhesive sheet, and is attached and fixed to a predetermined position on the ceiling 6 using this fastener. Bracket 5 also has a connecting part in its middle section that allows for adjustment of angle and orientation, such as a ball joint, and has the function of changing and adjusting the orientation and position of the case body 10, as well as fixing it in the desired position.

[0143] In this configuration, for example, when the drive recorder unit 4 is mounted on the ceiling 6 inside the vehicle, in the case of a hatchback type vehicle with a back door 7 that opens and closes on the rear side of the vehicle, or a glass hatch type vehicle where the rear window opens and closes, even when the back door 7 or rear window is opened and closed, the drive recorder unit 4 maintains its suspended and fixed position on the ceiling 6 and does not move with the back door 7, etc. Therefore, for example, when predetermined wiring such as a power cable and a communication cable is connected to the case body 10 of the drive recorder unit 4, the wiring can be routed inside the vehicle without becoming loose, which is advantageous.

[0144] The mounting part may be a mounting jig of various mechanisms and structures, such as the bracket 5 in this embodiment, but in a simple configuration, it may be attached to the ceiling using adhesive material such as double-sided tape on the upper surface of the case body 10. However, it is preferable to use a mounting component such as the predetermined bracket 5 so that it can be fixed securely.

[0145] A standalone camera can be used to record the rear of the vehicle, but it is preferable to install a rear camera from a 2-channel or higher drive recorder on the ceiling inside the vehicle. Also, when a drive recorder that records 360 degrees horizontally, such as a 360-degree panoramic drive recorder, is placed at the rear of the vehicle interior, it may be mounted on the rear window 3, but it is more preferable to mount it on the ceiling as in this embodiment.

[0146] (External mounting type) In the various embodiments and modifications described above, the case body 10 with the camera 11 mounted on it was installed inside the vehicle. However, for example, the drive recorder 1 may have a mounting part for attaching the case body 10 to a predetermined position outside the vehicle 2. This mounting part may be directly attached to the case body 10, or it may be a separate bracket or other fixing member.

[0147] For example, the windows of a vehicle other than the windshield, such as the rear window 3, are often made of privacy glass such as tinted glass. If the case body 10 with the camera 11 mounted on it is installed inside the vehicle, as in the embodiments described above, the image captured by the camera 11 will be difficult to see, or it would be preferable to use a camera 11 that can capture images clearly even through privacy glass. However, by installing it outside the vehicle, it is possible to capture images of the outside of the vehicle clearly regardless of whether or not there is privacy glass. A small rear camera that can be installed outside the vehicle in this way is advantageous because it can be installed on various types of vehicles regardless of whether or not the rear window is made of privacy glass.

[0148] When installing the case body 10 on the outside of the vehicle, it is best to install it in an inconspicuous location. Installing it in an inconspicuous location makes it less likely to be stolen. An inconspicuous location would be one where part of it is hidden by a vehicle part, such as next to or behind the license plate. Alternatively, the camera could be miniaturized and attached to, for example, the mounting bolts of the license plate, and its shape would be even less conspicuous if it resembled the mounting bolts.

[0149] (Shooting mode change type) The drive recorder unit 4 should have a function to change the shooting conditions according to the type of glass in the vehicle. When the case unit 10 with the camera 11 installed is placed inside the vehicle, the camera 11 will capture the scenery outside the vehicle by passing through the glass, but by shooting with shooting conditions according to the type of glass at the time of shooting, clear images can be captured regardless of the direction being photographed.

[0150] The shooting conditions should ideally allow adjustment of factors such as image brightness. For example, it would be beneficial to have a mode setting switch that allows for appropriate image quality when shooting both a clear glass windshield and a rear window with privacy glass.

[0151] In this way, when the drive recorder unit 4 is installed, for example, in a predetermined position at the rear of the vehicle interior, and the camera 11 is used to record the area behind the vehicle through the rear window 3, the area behind the vehicle can be clearly recorded by switching to a shooting mode that is compatible with tinted glass, etc. On the other hand, when the drive recorder unit 4 is installed, for example, in a predetermined position at the front of the vehicle interior, and the camera 11 is used to record through the windshield, for example, the area in front of the vehicle can be clearly recorded by switching to a shooting mode that is compatible with clear glass, etc. In this way, by providing a function to switch shooting conditions, one drive recorder can, for example, become a drive recorder for recording the front or a drive recorder for recording the rear.

[0152] Furthermore, while the above example involved a two-stage switch between clear glass and privacy glass, it would be preferable to have a two-stage switch to privacy glass of different densities, or even a three-stage or more switch.

[0153] (Variation of ball joint bracket) As described above in the embodiments and modifications, when a ball-joint type bracket 5 is used as the bracket 5 for attaching the case body 10 on which the camera 11 is mounted to a predetermined position inside the vehicle, it is preferable to provide a fixing means to fix the camera 11 so that its orientation does not change even when a biasing force is applied to the case body 10 after the drive recorder body 4 has been mounted to a predetermined position inside the vehicle and the camera's orientation and other positions have been determined.

[0154] For example, a typical ball joint uses the frictional force generated at the joint to fix the relative angle of the rods connected to both sides of the joint in a desired state. If a biasing force exceeding this frictional force is applied, the relative angle changes. This allows the orientation of the case body 10, and consequently the camera 11, to be adjusted to a desired direction so that it faces the appropriate shooting area. Furthermore, when fixed by the fixing means, even if a biasing force exceeding the frictional force fixing the joint is applied, the joint does not move, and the orientation of the camera 11, which photographs the area behind the vehicle, does not change. Therefore, for example, even if luggage comes into contact with the case body 10 on which the camera 11 is mounted when the back door is closed, the orientation of the camera 11 does not change, and it can photograph in the desired direction.

[0155] Users who are not conscious of dashcams, such as beginners, may not notice or even care if the camera 11's orientation changes due to biasing force applied to the case due to carelessness, for example. As a result, they may drive the vehicle with the camera in that changed orientation, potentially rendering the system useless as it fails to capture the desired area. In particular, dashcams that record the rear of the vehicle without a monitor cannot check the recorded footage on the spot. However, with this type of dashcam, where the camera's orientation does not change, once the desired area is set at the beginning, there is no need to check it afterward, which is an advantage.

[0156] The fixing mechanism should ideally be a physical fixation that prevents the orientation from changing. For example, using a physical lock such as a pin, which can be inserted to prevent rotation, allows for a simple configuration and is therefore preferable.

[0157] As mentioned above, a drive recorder mounted using a ball-joint bracket with a fixing means other than friction is not limited to rearward recording, but can be applied to drive recorders and other systems that record in various directions. For example, when applied to a drive recorder that records the front of the vehicle, the drive recorder will be mounted in a predetermined position above the windshield. In such a case, for example, when a sunshade is placed on the windshield when parked in the summer, the camera's orientation will not change even if the sunshade hits the drive recorder when it is being installed or removed.

[0158] (General-purpose cable connection type) As shown in Figure 6, it is preferable to connect the housing 31 of the camera unit, which houses a camera 11 that captures areas outside the vehicle other than the front, with another housing 32 that has means for outputting to a recording unit that records the video captured by the camera 11, using a general-purpose cable 33 that transmits audio signals and video signals.

[0159] In this way, by using a general-purpose cable 33, the camera unit that implements the camera 11, which captures areas outside the vehicle other than the front of the vehicle, can use a general-purpose product compatible with the general-purpose cable or a backup camera from another company. For example, by using a camera unit compatible with 24V systems such as trucks, it can be used as a drive recorder for 24V vehicles such as trucks. The general-purpose cable 33 can be, for example, an RCA cable.

[0160] Furthermore, for example, the housing 31 only needs to be equipped with at least the camera 11, and if the first LED 12, control unit 14, card slot 15, notification unit 20, etc., as in the various embodiments described above are mounted in a separate housing 32, the housing 31 can be further miniaturized.

[0161] Furthermore, it is preferable to provide an output terminal on another housing 32, for example, for connecting with a general-purpose cable that transmits audio and video signals. In this case, by connecting a general-purpose monitoring device to the output terminal, the video captured by the camera 11 can be output to the monitoring device while also being output to a recording unit such as a memory card 19, allowing the recording unit to record the video. In this case, a general-purpose product can also be used as the monitoring device, which is preferable because it broadens the range of equipment to be selected when configuring the system.

[0162] Furthermore, in the case of a system equipped with multiple cameras that capture different directions, it is advisable to use cameras that can be added using general-purpose cables, which is beneficial as it allows for compatibility with vehicles that require additional cameras, such as those with interior or external cameras.

[0163] (Dashcam with parking surveillance mode) A dashcam should have a first mode for recording video while the vehicle is running and ready to drive, such as when the engine is running, and a second mode for recording video while parked. The first mode is the standard dashcam mode for recording video, and may include a continuous recording mode for constant recording or an event recording mode for recording when a predetermined event occurs. The second mode is a parking surveillance mode and may include modes for recording periodically regardless of whether a predetermined event occurs, similar to the continuous recording mode in the first mode, or recording when a predetermined event occurs, such as a person approaching or entering the vehicle or vandalism. In such cases, it is preferable to have a function to reduce battery consumption by making the sampling time for periodic recording longer than that of the first mode. It is even preferable to have multiple sampling times available and a function to switch between them via settings. Thus, this form of dashcam has the function to record with different recording settings for the first and second modes. The dashcam itself should have this setting switching function so that the settings can be switched from the dashcam itself.

[0164] Furthermore, this drive recorder acquires information from the vehicle's ACC (Adaptive Cruise Control), and the control unit 14 has a function to determine whether the current state of the vehicle is running or parked, and has a function to switch between the first mode and the second mode according to the vehicle's state, and a function to switch the recording settings to those corresponding to each mode when switching. In this way, recording can be performed with recording settings appropriate for each situation, whether the vehicle is running or parked.

[0165] Furthermore, it would be beneficial to allow the recording settings for the first and second modes to be configured from, for example, the drive recorder unit itself. Additionally, it would be good to include a function in the drive recorder unit to change and set the power supply time from the vehicle's battery while parked. This would allow various settings to be easily changed by operating the drive recorder unit itself.

[0166] (A dashcam that connects a main case with a camera and a second case with a monitor, allowing the camera's orientation to be changed.) Figure 7 shows a drive recorder in which a case body 10 equipped with a camera 11 that captures areas other than the front of the vehicle is connected to a second case body 42 equipped with a monitor 41. In this example, the second case body 42 has a flat, roughly rectangular shape, and the monitor 41 is positioned on one large surface. This second case body 42 is attached to a predetermined position on the vehicle by a bracket or the like (not shown), and when attached, the monitor 41 faces inward into the vehicle interior, and is set to a position where the driver can see the monitor 41.

[0167] The case body 10 is connected to one of the left or right sides of the second case body 42 via a predetermined rotating mechanism, and is mounted so as to be rotatable in both forward and reverse directions within a predetermined angular range along that side. The case body 10 can rotate while, for example, the position of the second case body 42 is fixed by the rotating mechanism. The drive recorder is equipped with a fixing means that allows the relative angular position with respect to the second case body 42 to be fixed at a desired position. This makes it possible to change the orientation of the camera 11 while the case body 10 and the second case body 42 are connected, and the orientation of the camera 11 can be changed relative to the orientation of the monitor 41. For example, the monitor 41 can be installed in a position that is easy for the driver to see, and the orientation of the camera 11 can be changed to capture images in a desired direction, which is desirable.

[0168] Furthermore, the device equipped with the monitor 41 in this form may be, for example, the housing of another device, which may be, for example, a drive recorder that records the front of a vehicle. In this configuration, the second case body 42 becomes the main body of the drive recorder for front recording, and has a camera 43 on the side opposite to the side with the monitor 41. The second case body 42 contains a control unit that displays the video captured by the camera 43 on the monitor 41, and records the captured video etc. on a memory card 44. The left and right sides of the second case body 42 that do not have the case body 10 attached have a card slot 46 and a power jack 47. A connector 49 provided at one end of a power cable 48 is connected to this power jack 47, and the other end of the power cable 48 receives power from the battery of the connected vehicle.

[0169] Regarding the mounting positions of the case body 10, card slot 46, and power jack 47 on the second case body 42, as shown in the diagram, the left side of the monitor 41 should be the mounting surface for the case body 10, and the right side should be the mounting surface for the card slot 46 and power jack 47. This arrangement is advantageous because it makes it easier for drivers of right-hand drive vehicles, which are mainly sold in Japan, to insert and remove the memory card 44.

[0170] It is preferable to provide power lines and communication lines at the connection point between the main case body 10 and the second main case body 42, so that power is supplied to the equipment inside the main case body 10 from the power circuit side of the second main case body 42, and that communication is established between the equipment installed inside the main case body 10 and the equipment installed inside the second main case body 42. For example, it is preferable to send video data captured by a camera to the second main case body 42 and display it on the monitor 41 or record it on a recording device. In addition, the operation control of the equipment inside the main case body 10 may be performed by installing a control unit inside the main case body 10, but it is preferable to have the control based on commands from the control unit in the second main case body 42.

[0171] A first LED 12 is provided on the side of the case body 10 where the camera 11 is positioned. If this first LED 12 is set to light up, for example, during recording, then even if the monitor 41 displays the video captured by the camera 43 that captures the front view, and the video captured by the camera 11 that captures areas other than the front view is not displayed, the operating status of the camera 11, such as whether or not it is recording, can be determined.

[0172] In this embodiment, the fixing means can be implemented with a simple configuration, as shown in Figure 7(b), by forming triangular wave-shaped irregularities 45 continuously or discretely on the circumference of a circle with the same center and diameter on the opposing surfaces of the case body 10 and the second case body 42, and fixing the angle at the position where the irregularities interlock. Furthermore, arranging continuous triangular wave shapes as shown in the figure is advantageous because it allows for fine positioning of the angle at the pitch interval of the peaks and valleys of the triangles. Alternatively, for example, recesses such as hemispherical ones could be formed on one surface at a predetermined angular pitch, and protrusions corresponding to those recesses could be formed on the other surface, allowing the orientation to be changed in relatively large angular units (e.g., 10 degrees, 15 degrees, ...) by having the protrusions correspond to either recess. However, it is preferable to allow for change and fixing at fine pitches as in this embodiment.

[0173] The predetermined angle range may be a full rotation, such as 360 degrees, but it is preferable to set it to a predetermined acute angle. The range of rotational movement should also be configured such that, for example, the angle between the imaginary line indicating the vertical direction with respect to the rotation centers of the case body 10 and the second case body 42 is 0 degrees, and both the case body 10 and the second case body 42 are upright, and the case body 10 tilts forward from that reference position, allowing the camera 11 to point diagonally downwards, and the device rotates in both forward and reverse directions within a predetermined angle range (see Figure 7(b), etc.) to allow for positioning and angle adjustment.

[0174] In particular, if the second case body 42, which houses the case body 10 with the camera 11 installed, is a drive recorder that records the area in front, the mounting position of the second case body 42 is often near the top of the windshield of the vehicle 2. When the case body 10 is tilted diagonally upward in this upward mounting position, the shooting area of ​​the camera 11 will include a large portion of the interior ceiling. Therefore, this configuration is suitable for switching the shooting range, such as by standing the case body 10 upright so that the camera 11's field of view is horizontal to the rear of the vehicle, and shooting the area outside the vehicle through the interior, or by tilting it towards the front to mainly shoot the interior of the vehicle.

[0175] The camera 11 in this configuration photographs the area inside the vehicle and the area outside the vehicle behind the vehicle through the interior, so its shooting area is an area that is not illuminated by the vehicle's lights, at least while the vehicle is in motion. Therefore, it is preferable to use a highly sensitive camera that can shoot even in low light, such as an infrared camera or a camera using STARVIS®.

[0176] Alternatively, a memory card could be installed in the case body 10, and the video captured by the camera 11 could be recorded on the memory card in the case body 10. However, as in this configuration, it is preferable to record both the video of areas other than the front captured by the camera 11 and the video of the front of the vehicle captured by the camera 43 onto a single memory card 44 that is detachably installed inside the second case body 42. When recording the video captured by both cameras onto a single memory card 44, it is preferable to record them into different folders.

[0177] Furthermore, in this configuration, it is preferable to have a function to select the display mode on the monitor 41 from the settings menu, such as "single-screen display" or "two-screen display". In the case of "single-screen display", for example, the forward-facing image captured by camera 43 is displayed, and in the case of "two-screen display", for example, as shown in Figure 8, the image 37 of a vehicle other than the front, captured by camera 11, is displayed in a small area overlaid on the forward-facing image 36 captured by camera 43. It is preferable that the small area be switchable by setting, for example, the driver side should be set as the initial position as shown in the upper right.

[0178] Figure 9 shows that a first camera unit 51 for capturing areas other than the front and a second camera unit 52 for capturing the front of the vehicle are arranged side by side on the lower side of the second case body 42 equipped with a monitor 41.

[0179] The first camera unit 51 attaches a main body 51b equipped with a camera 51a to the second case body 42 via a first mounting part 51c. The camera 51a is positioned so as to face the same side as the monitor 41, that is, facing the interior of the vehicle. The main body 51b and the first mounting part 51c may be separate and detachable parts or a single, non-detachable unit, but it is preferable that the camera 51a can rotate within a predetermined angular range, allowing the camera 51a's field of view to be changed and adjusted. The center of rotation should, for example, be parallel to the direction in which the left and right sides are aligned, and it is preferable that the camera 51a can be rotated forward and backward.

[0180] The second camera unit 52 attaches a main body 52b equipped with a camera 52a to the second case body 42 via a second mounting part 52c. The camera 52a is positioned to face the side opposite to the monitor 41, i.e., towards the front of the vehicle. The main body 52b and the second mounting part 52c may be separate and detachable parts or a single, non-detachable unit, but it is preferable that the camera 52a rotates within a predetermined angular range, allowing the camera 52a's field of view to be changed and adjusted. The center of rotation should, for example, be parallel to the direction in which the left and right sides are aligned, and it is preferable that the camera 52a can be rotated forward and backward.

[0181] In this configuration as well, it is preferable to use a highly sensitive camera capable of shooting even in low light conditions, such as an infrared camera or a camera utilizing STARVIS®. It is also preferable to have a function to record the images captured by cameras 51a and 52a onto a single memory card, or to display both images simultaneously on a monitor.

[0182] (Drive recorder with additional cameras) As shown in Figures 10 to 12, a housing 61 that mounts a camera 11 for capturing images of the area outside the vehicle other than the front of the vehicle, and a main unit 62 are rotatably connected via a connecting member at their center of rotation. If the housing 61 and the main unit 62 are both cylindrical in shape with the same diameter, for example, by connecting their sides, they form a continuous cylindrical shape as a whole.

[0183] In this configuration, the main unit 62 is also equipped with a camera 63. This camera 63 captures a different area than camera 11. For example, the camera 63 mounted on the main unit 62 may capture the area in front of the vehicle, while the camera 11 mounted on the housing 61 may capture the area outside the vehicle at the rear, for example, through the interior of the vehicle.

[0184] The main unit 62 is mounted, for example, by attaching a bracket 64 to the side of the housing 61 opposite to the connection surface, and then mounting it to the vehicle's windshield or other predetermined location via the bracket 64. The main unit 62 is equipped with a mechanism that allows the relative angle with respect to the bracket 64 to be changed using the central axis of the main unit 62 as the center of rotation, and to be fixed at a predetermined angle position. This makes it possible to change and adjust the orientation of the camera 63 by rotating it vertically while it is mounted to a predetermined location such as the windshield via the bracket 64.

[0185] Furthermore, the side of the main unit 62 to which the bracket 64 is attached is provided with a card slot 65. The side opposite to the side with the card slot 65 becomes the connecting surface of the housing 61. This connecting surface is formed such that a cylindrical peripheral wall 66 extends axially along its outer circumference. As a result, a recess 67 is formed on the inside of the peripheral wall 66, and a pin jack 69 is provided at the center of the back surface 68 of the recess 67. In addition, the inner peripheral surface at the tip of the peripheral wall 66 is provided with triangular wave-shaped irregularities 70 along the circumferential direction.

[0186] The housing 61 on which the camera 11 is mounted has an overall cylindrical external shape, with the outer diameter of the connecting end portion 71 being smaller, and this smaller-diameter end portion 71 being inserted into the recess 67 of the main unit 62. A pin plug 73 for insertion into a pin jack 69 is positioned protruding from the center of the tip surface of the end portion 71. As the end portion 71 is fitted into the recess 67, the pin plug 73 is inserted into the pin jack 69, and a mechanical and electrical connection is established. These pin jack 69 and pin plug 73 constitute a connecting member.

[0187] With the pin plug 73 inserted into the pin jack 69, if the main unit 62 and the housing 61 are biased to rotate relative to each other around a central axis, the main unit 62 and the housing 61 will rotate around that central axis. As a result, for example, if the angular position of the main unit 62 is fixed, the housing 61 will rotate, and the orientation of the camera 11 mounted on the housing 61 will change in the vertical direction.

[0188] Furthermore, the equipment inside the housing 61 and the equipment inside the main unit 62 are electrically connected by connecting components consisting of a pin jack 69 and a pin plug 73. Even if the relative angle between the housing 61 and the main unit 62 is rotated and changed, the connection will not break, making it less prone to damage. By placing the pin jack in the center of the cylindrical shape, it becomes an integrated 2-camera unit without using FPCs / wires, etc.

[0189] A positioning projection 74 is provided on the inner side of the outer circumferential surface of the side end 71 of the housing 61. The positioning projection 74 fits into the valleys of the triangular wave-shaped irregularities 70 provided on the tip side of the peripheral wall 66 of the main unit 62, thereby fixing the rotation angle in position.

[0190] When using pin jacks and pin plugs as connecting components, as in the main unit, it is possible to either directly connect the pin plugs 73 and pin jacks 69 provided on the housing 61 and the main unit 62, respectively, to integrate the housing and the main unit, or, as shown in Figure 12, connect the pin plugs 73 and pin jacks 69 via a connecting cable 75 to separate the housing 61 and the main unit 62. Separating them increases the degree of freedom in setting the field of view direction of the camera 11 on the housing 61, which is advantageous.

[0191] By lengthening the connecting cable 75, for example, the main unit 62 can function as a drive recorder that records the area in front of the vehicle, while the housing 61 on which the camera 11 is mounted can be positioned, for example, near the rear window, to function as a camera for recording the rear view.

[0192] Furthermore, the bracket 80 for attaching the housing 61 to the rear glass or the like may be provided with, for example, a ring-shaped mounting portion 81 and an attachment portion 82 provided on the outer circumference of the mounting portion 81, as shown in Figure 10. The mounting portion 81 has a shape equivalent to, for example, the peripheral wall 66 of the main unit 62, and has triangular wave-shaped protrusions 83 along the circumferential direction on the inner surface of one end edge in the axial direction. When the side end portion 71 of the housing 61 is inserted into the mounting portion 81, these triangular wave-shaped protrusions 83 engage with positioning projections 74 provided on the side end portion 71, fixing its position in the rotational direction.

[0193] Furthermore, the outer circumferential surface of the side end portion 71 is provided with a guide groove 76 extending in the circumferential direction at a position set back from the tip side, and a notched groove 77 connecting the tip of the side end portion 71 to the guide groove 76. In addition, a guide projection 84 projecting toward the center is provided at a predetermined position on the inner circumferential surface of the mounting portion 81 of the bracket 80. When the mounting portion 81 is attached to the side end portion 71 of the housing 61, this guide projection 84 moves within the notched groove 77 provided in the side end portion 71, and when it reaches the guide groove 76, it moves along the guide groove 76. As this guide projection 84 moves along the notched groove 77 and the guide groove 76, the mounting portion 81 moves axially forward and backward relative to the side end portion 71 of the housing 61, or rotates around the central axis as the center of rotation. When it rotates, the triangular wave-shaped protrusions 83 move relative to each other in the circumferential direction while overcoming the positioning projection 74, and the rotation angle is fixed and the mounting portion is positioned at the valleys of the triangular wave-shaped protrusions 83. Although this explanation is out of order, as shown in Figure 12, guide protrusions 78 are provided at predetermined positions on the inner surface of the peripheral wall 66, similar to the guide protrusions 84. When connecting the housing 61 and the main unit 62, it is preferable to position the guide protrusions 84 in the guide groove 76 via the notched groove 77 and fix them in place.

[0194] The bracket 80, and thus the housing 60, is attached to the predetermined position on the rear window 3 by attaching, for example, double-sided tape or other adhesive material to one side of the mounting portion 82 of the bracket 80, and attaching the other side of the adhesive material to, for example, the rear window. Note that the mounting position of the bracket 80 is not limited to the rear window; it may be attached to, for example, the ceiling near the rear window or any other location on the vehicle.

[0195] The positioning projections 74 of the bracket 80 and / or housing 61 are preferably made of an elastically deformable material such as resin. This is advantageous because, for example, with the bracket 80 attached to the side end 71 of the housing 60, the bracket 80 can be fixed to the rear glass or the like, and the housing 60 can be rotated relative to the bracket 80 in that state to adjust its angular position and fix it at a desired angle.

[0196] The connection structure using the pin jack 69 and pin plug 73 is suitable, for example, for the connection part when rotatably connecting a case body 10, which has a camera mounted on it, to a second case body equipped with the monitor described above.

[0197] (An embodiment in which multiple dashcams equipped with cameras record individually) As shown in Figure 13, this system includes a first drive recorder 87 equipped with a first camera 85 that captures areas outside the vehicle other than the front of the vehicle, and a first recording unit 86 that records the video captured by the first camera 85, and a second drive recorder 90 equipped with a second camera 88 that captures a different direction from the first camera 85, and a second recording unit 89 that records the video captured by the second camera 88. Both the first drive recorder 87 and the second drive recorder 90 are devices that are installed on the vehicle afterward.

[0198] In this embodiment, images from different directions can be captured by each camera, and the captured images can be recorded in the first recording unit 86 and the second recording unit 89, respectively. The first recording unit 86 and the second recording unit 89 may both be memory cards such as SD cards, and the memory cards may be removable. The first drive recorder 87 may not have a monitor, but may be equipped with an LED or the like to indicate the operating status.

[0199] Unlike the first drive recorder 87, the second camera 88 of the second drive recorder 90 may capture areas other than "areas outside the vehicle other than in front of the vehicle," such as the area in front of the vehicle or the interior of the vehicle. However, it is preferable that it captures "areas outside the vehicle other than in front of the vehicle," similar to the first drive recorder 87. This is advantageous because it allows capturing different directions of "areas outside the vehicle other than in front of the vehicle." Also, although the illustrated example shows only one second drive recorder 90, it is preferable to have multiple second drive recorders 90.

[0200] The first drive recorder 87 and the second drive recorder 90 may be supplied with power separately, but it is preferable to use a power direct connection cord 91 with one end branched to supply power to both the first drive recorder 87 and the second drive recorder 90 simultaneously.

[0201] Furthermore, if, for example, the first drive recorder 87 or the second drive recorder 90 is installed at the rear of the vehicle and power is supplied from the vehicle's battery, it is best to supply power from the power source located in the trunk when installing them in a vehicle where power (accessories) can also be obtained from the trunk.

[0202] As shown in Figure 14, it is desirable to have a function that simultaneously displays the video footage captured by the first drive recorder 87 and the video footage captured by the second drive recorder 90 on the same monitor. In this way, it is possible to compare videos from different directions, captured at the same time, on the same screen.

[0203] The monitor can be, for example, the monitor built into the second drive recorder 90, but it is preferable to use the monitor of another device, such as a smartphone 92. Using another device such as a smartphone 92 is preferable because it can be placed close to the user, such as the driver, allowing for close viewing and the use of a larger screen size. The connection between the first drive recorder 87 or the second drive recorder 90 and the smartphone is preferably made wirelessly, and if a wireless connection is used, Wi-Fi is even more preferable.

[0204] Displaying the same information simultaneously is best done when playing back recorded video, and even better in real time. For example, when playing back recorded video, if there is a chain reaction accident, it is good to be able to check whether it was caused by your vehicle or if you were rear-ended. When done in real time, it is preferable to be able to view video from different directions and drive while being aware of the surrounding situation. In particular, even if the vehicle does not have an onboard camera to record the surroundings, it is possible to implement a function to record the surroundings aftermarket, which is good because you can drive while checking the safety of your surroundings, for example when reversing the vehicle, changing direction, or driving on a road with poor visibility.

[0205] As an example of how the video can be displayed, for example, as shown in Figure 14(a), the display screen of the smartphone 92 can be used in portrait orientation, divided into upper and lower sections, and the video recorded by the first drive recorder 87 and the second drive recorder 90 can be output and displayed in the upper and lower sections, respectively.

[0206] Figure 14(b) shows an example of a settings screen for wirelessly connecting a first drive recorder (e.g., rear camera) and a second drive recorder (e.g., front camera) to a smartphone 92. In this embodiment, the Wi-Fi connection function of the smartphone 92 is used to attempt the connection. Once communication is established, the control unit of the smartphone displays the video sent from the corresponding drive recorder in a video display area located at the top of the display screen.

[0207] (An embodiment of a system in which multiple drive recorders equipped with cameras work together) In this system, the first and second drive recorders, installed in different locations on the vehicle, are made capable of communicating with each other. Based on the operating status of one drive recorder, the video captured by the other drive recorder is output to the recording unit.

[0208] With this configuration, the first and second drive recorders will more reliably output video to the recording device when a situation requiring recording occurs. Communication between the drive recorders can be wired, but wireless communication is preferable.

[0209] For example, the first and second drive recorders are equipped with an event recording mode that triggers event recording when an impact exceeding a certain level occurs. In such a case, when one drive recorder detects an impact, it notifies the other drive recorder. As a result, one drive recorder performs event recording triggered by the impact it detected, and the other drive recorder performs event recording triggered by the received notification. This ensures that even if the impact on the vehicle is weak and only one system detects the impact, both drive recorders can perform event recording.

[0210] Furthermore, each dashcam periodically sends video signals to the other for monitoring, and if video from the other dashcam becomes unavailable, it triggers event recording even if no impact is detected. By coordinating triggers between the first and second dashcams, which are located in different places, recording can be more reliably performed when necessary.

[0211] (Linking multiple dashcams with a smartphone) The first and second drive recorders each have a camera and a recording unit that records video footage captured by the camera. In this configuration, the first and second drive recorders each communicate with a terminal such as a smartphone.

[0212] When the terminal meets certain conditions, it simultaneously sends a recording trigger to the first and second drive recorders with which it is connected. Upon receiving this trigger, the first and second drive recorders initiate event recording. As a result, when an event occurs, the first and second drive recorders each record video based on the trigger from the terminal, allowing for recording of video from different angles at the time the event occurred.

[0213] For example, if the device is a smartphone, it would be good to configure it to output a trigger based on the output of sensors such as a G-sensor, gyroscope, and GPS implemented in the smartphone. The trigger conditions should ideally allow for combinations of multiple sensors. Furthermore, it would be beneficial to install an app on the smartphone that allows users to configure which sensors trigger when and under what conditions. The user would then use this app to set the trigger output conditions.

[0214] Triggers from smartphones should ideally be based on communication. Communication-based triggers can be sent to a designated dashcam when a specific pattern occurs using IFTTT, when a phone call is received, or when certain conditions are met based on information on the web (for example, when the temperature at the current location exceeds 35 degrees Celsius). Triggers should be able to be assigned arbitrary tags (ideally multiple tags) via the app, and the information from these tags should also be associated with the trigger and sent to the system. The system should then start event recording based on the trigger, and record the video footage in association with the received tags.

[0215] In the system described above, triggers are sent simultaneously to the first and second drive recorders. However, it is also possible to send triggers to specific drive recorders depending on the conditions. For example, the application settings described above should include a function to identify the destination drive recorder.

[0216] (Memory card alert function) In the embodiments and modifications described above, examples are explained in which a memory card such as an SD card is used as the recording unit for recording the video captured by the camera. Since a large number of bad sectors are generated in memory cards such as SD cards with use, formatting is necessary. Therefore, the drive recorder in this embodiment is equipped with a function that alerts the user when a certain period of time has elapsed since use.

[0217] For example, the frequency of use differs between someone who commutes or works and a Sunday driver, so the timing of when a large number of bad sectors occur will also differ. In this configuration, the system uses usage time as a basis and issues an alert prompting formatting when the usage time reaches a set threshold. For example, if the drive is used frequently, the alert will occur in a relatively short cycle, while if it is not used often, the interval between alerts will be longer. The timing is delayed, and the alert is issued at a time appropriate for each individual's usage situation.

[0218] This configuration is characterized by outputting an alert without automatically formatting the device. Automatic formatting has the problem of potentially erasing recorded footage without the user's knowledge, but this configuration avoids such a situation. Usage time can be determined, for example, based on recording time or GPS logs.

[0219] (An embodiment of a system equipped with a camera that captures areas other than the rear of the vehicle: side camera) For example, in a system that includes a monitor device 21 separate from a case body 10 equipped with a camera 11 as shown in Figure 3, the case body 10 is mounted at a predetermined position on the vehicle so that the area outside the vehicle diagonally in front of the vehicle is within the shooting range of the camera 11, and the monitor device 21 is installed in a position visible to the driver, such as on the dashboard of the vehicle 2. In this way, the video footage of the area outside the vehicle diagonally in front of the vehicle is output to the monitor device 21. Therefore, even in vehicles that do not originally have a side view monitor, this system can be used to perform the function of a side view monitor.

[0220] This system should have a function to acquire vehicle information for detecting left / right turns and lane changes, such as turn signal information and steering angle information. The control unit 14 should not normally output video captured by the camera 11 that photographs the area diagonally in front of the vehicle to the monitor device 21. When it detects a change in the direction of travel, such as a left / right turn or lane change, based on the acquired vehicle information, it should have a function to automatically switch the video output to the monitor device 21 to the video captured by the camera 11. In particular, if the monitor device 21 uses the monitor of another device, it should normally output and display video related to the operation of that other device, and display the camera video when the above conditions are met. This camera video may be displayed together with the video normally displayed, but it is preferable to switch to displaying the camera video on a separate screen.

[0221] In particular, it would be beneficial to have a function that links the switching to the vehicle's speed. For example, if the vehicle is stopped with a speed of 0 and the turn signal indicates a right or left turn, the function should automatically switch and output the video of the direction of the turn. This would be beneficial because it would allow drivers to check the situation in the direction of travel, even at intersections with poor visibility.

[0222] Furthermore, a function linked to the vehicle's speed would be beneficial. For example, if the vehicle is slowly changing direction based on steering angle information without using the turn signal, it would be good to automatically switch to the camera feed showing the area outside the vehicle in the direction of the change. When slowly changing direction to the left or right in this manner, there is a high probability that the driver is pulling over to park, so displaying the area outside the vehicle in the direction of the pull-over on the monitor would allow for safer pulling over. For example, when parking on a narrow road, there is a desire to park as close to the left or right as possible. However, there is a risk of not being able to pull over sufficiently due to concerns such as the tires falling into an open ditch or driving onto a curb. By being able to check the situation in the direction of the pull-over on the video feed, it becomes possible to pull over appropriately. Even drivers who lack a sense of vehicle width can check the area around the front and rear tires and confirm their sense of vehicle width, which is beneficial. It would be particularly good to have the automatic switching occur when pulling over to the opposite side of the driver's seat (for example, the left side in the case of a right-hand drive vehicle). This allows you to check the blind spot on the opposite side of the driver's seat (for example, the left side of a right-hand drive vehicle) on the monitor without having to switch between modes.

[0223] While this system doesn't necessarily require a function to record video captured by the camera, it would be beneficial to include such a function. Recording the captured video allows for verification of the circumstances at the time of contact with an object while turning right or left, such as whether the other object hit the vehicle first or if the vehicle collided with a stationary object. It also allows for later review of the driving conditions at the time, even if there is no collision or wheel coming off the road.

[0224] (An embodiment of a system equipped with cameras that capture images other than the rear of the vehicle: tire monitoring camera) Furthermore, in a system that includes a monitor device 21 separate from the case body 10 on which the camera 11 is mounted, for example, the case body 10 may be mounted at a predetermined position on the vehicle so that the area including the vehicle's tires is within the camera's field of view, and the monitor device 21 may be installed in a position visible to the driver, such as on the dashboard of the vehicle 2. In this way, it becomes a tire monitoring camera. It is particularly preferable to implement this on large vehicles. For example, it is possible to visually check whether there are any foreign objects (e.g., people or objects) around the tires when starting the vehicle, or to visually check whether there are any abnormalities in the tire pressure. This can be checked "visually" from the driver's seat without using equipment such as TPMS. This is particularly good as a product for large vehicles.

[0225] (Additional rear camera) For example, if a 360-degree all-around dashcam, which has the function to capture a 720-degree range (360 degrees horizontally and 360 degrees vertically) when installed, is mounted on the windshield, the camera's field of view will be limited to, for example, the front of the vehicle or the interior of the vehicle. This is good for checking the rear of the interior, but there are limitations to recording following vehicles.

[0226] Therefore, it would be beneficial to make a 360-degree drive recorder, which can also record the rear of the vehicle, compatible with a rear camera. A rear camera would be connected to the 360-degree drive recorder and mounted on the rear window or similar location. This rear camera would capture the area behind the vehicle and record following vehicles, thus resolving the aforementioned problem.

[0227] Furthermore, it would be beneficial to include a function to connect additional cameras to various types of dashcams, not just 360-degree dashcams. This would allow the dashcam to capture and record areas different from those captured by the camera built into the main unit. The dashcam should have the capability to record in two or more channels and should include a connection port for additional cameras. While the connection between these additional cameras, such as rear cameras, and the dashcam can be done via a wired connection cable, it is preferable to use a wireless communication method such as Wi-Fi.

[0228] For example, in vehicles that frequently travel during the day, such as taxis, and are at risk of being involved in accidents, installing a dashcam that records the outside of the vehicle allows the recorded footage to be used as evidence in the event of an accident. Connecting an additional camera capable of recording the interior or rear of the vehicle to such a dashcam is beneficial, as it allows for recording interactions with passengers and the area behind the vehicle. For example, when recording the interior, the dashcam and additional camera should be mounted, for example, near the upper center of the windshield, in the front center of the ceiling inside the vehicle, or on the rearview mirror, and configured to record from the side of the rearview mirror. In particular, it is best to configure it to record from the side adjacent to the rearview mirror.

[0229] (A form that utilizes video from an in-vehicle camera) It is preferable that the device, which is installed on the vehicle afterward, has the function of acquiring and hacking video footage captured by the vehicle's onboard camera. A device equipped with such function can utilize the video footage captured by the onboard camera.

[0230] The device should ideally include a means for outputting video acquired by an in-vehicle camera mounted on the vehicle to a recording unit that records the acquired video. In this way, the device can record external video, such as a dashcam, without using a camera.

[0231] Furthermore, it would be desirable for devices installed later on a vehicle, such as a dashcam with a camera, to have a function to acquire video footage captured by the vehicle's onboard camera. This is preferable because it allows acquiring video footage from an onboard camera that captures a different area than the installed camera, eliminating the need to separately prepare optional accessories such as additional cameras and the associated wiring.

[0232] The in-car camera to connect should ideally be a rearview camera, such as those used for back-view monitors, that captures the area behind the vehicle. While rearview cameras are angled downwards and therefore not sufficient for capturing distant objects behind the vehicle, they can adequately capture approaching vehicles (for example, during tailgating or rear-end collisions).

[0233] (Dashcams with unusual external shapes, etc.) For example, in the case of a system such as a dashcam, if its external shape is not rectangular, it would be good to create a collaborative product with a character that suits that external shape. For instance, with devices and products such as 360-degree dashcams, the spherical lens facing into the car interior is conspicuous, making passengers aware that they are being filmed, and the spherical shape of the lens may stand out and give a clunky impression. Therefore, if a system with an external shape that is not rectangular in part or entirely is created as a collaborative product with a character that suits that external shape, the aforementioned impression can be mitigated, making the product easier for users to use and implement, thus solving the above problem.

[0234] For example, in the case of a 360-degree dashcam with a camera that has a spherical shape, characters such as "Medama Oyaji (Kitaro)", "Mike Wazowski (Monsters, Inc.)", or balls used in ball games (soccer, basketball, golf, baseball, etc.) would be good choices, and it would be good to create a collaborative product in which the spherical part of the camera is shaped to resemble the character.

[0235] (Viewer) A viewer for a system comprising a first system such as a drive recorder that has a camera that photographs an area outside the vehicle other than the front of the vehicle and outputs the image captured by the camera to a recording unit, and a second system which is a device that is installed on the vehicle afterwards and has a camera that photographs in a different direction from the first system and outputs the image captured by the camera to a recording unit, is preferable to have a function that displays the mounting positions of the first system and the second system, for example, the mounting positions of the cameras in each system.

[0236] This viewer should ideally include, for example, an editing mode and a viewing mode. In editing mode, for example, when a car diagram or shape is displayed and the user clicks on the location where a camera is placed within that diagram, a frame representing the camera's location should be drawn. The drawn frame should be color-coded to indicate which camera it represents. In viewing mode, the viewer should have a function to play and display video captured by one or more designated cameras, and when playback is performed, the frame of the triggered camera should, for example, blink. The frame color should be the same as the frame color of the graph or playback screen.

[0237] The mounting location can be indicated, for example, by displaying a top-down view of the car on the viewer, and marking the area on the car's shape corresponding to the camera's mounting position in a way that clearly indicates it is the camera's location. This makes it easy to see where the camera is installed. For example, the approximate area being captured by the camera can also be understood from its mounting position.

[0238] To indicate the camera's position, for example, a designated shape or icon should be displayed at the corresponding location. The viewer can be implemented using various methods such as a PC viewer, web viewer, or application.

[0239] The embodiments, modifications, and other forms described above were primarily explained using a drive recorder that records areas outside the vehicle other than the front as an example, but they are not limited to drive recorders and can be applied to various devices and systems. Furthermore, some or all of the components and elements of the embodiments, modifications, and other forms described above can be applied to or combined with drive recorders and other systems that primarily record the area in front of the vehicle.

[0240] Furthermore, in a two-camera type dashcam equipped with, for example, a camera that films the front of the vehicle and a camera that films the rear of the vehicle, it would be beneficial to have a function that provides at least one of the following: an alert or recording, when the size of the area that can be considered to be a vehicle in the image captured by, for example, the rear camera reaches a size that can be judged as approaching. The size of the object to be judged could be, for example, at least one of width, height, or area.

[0241] Furthermore, it would be beneficial to have a function that provides at least one of the following: an alert or recording, when the size of the area that can be identified as a vehicle in the camera image of the front of the vehicle becomes large enough to be judged as approaching.

[0242] The function for detecting approaching vehicles behind or ahead is not limited to images captured by a designated camera, as mentioned above. It is preferable to incorporate sensors that measure the distance between vehicles and perform the detection based on these sensors, or to use them in combination, but it is preferable to perform the detection based on images captured by a camera.

[0243] The system should have a function to set separate criteria for detecting approaching vehicles behind and approaching vehicles ahead, and it is preferable to set different criteria. Using distance as the detection criterion is preferable for more accurate determination, but it is not limited to directly calculating distance. It is preferable to configure the system to detect approaching vehicles based on something that changes in response to the calculated distance, without the need for a simple method or special sensors. For example, something that changes in response to distance could be the size of the area that can be considered a vehicle in the image captured by the aforementioned camera.

[0244] If the system includes a function to trigger an alarm or record information upon approach, it would be beneficial to include a function to set the conditions for the alarm and recording separately.

[0245] If the system includes a function to trigger an alarm or record information upon approach, it would be beneficial to include a function to set whether or not to trigger the alarm and record information, respectively.

[0246] It is preferable to have a recording function only on the unit of the camera that captures the front view, and to connect the unit of the camera that captures the rear view to the unit of the camera that captures the front view. In this case, the setting function for the unit of the camera that captures the rear view, and the setting for processing based on the video captured by the rear view camera, should be provided on the unit of the camera that captures the rear view. The camera that captures the rear view will operate according to the settings made by that setting function.

[0247] It would be beneficial to have a function that allows recording both front and rear approach footage onto the same recording medium, and when recording onto the same medium, it would be best to record the front and rear approach footage into separate folders.

[0248] It would be best to record forward approach recordings and rear approach recordings as separate types of recordings that can be displayed in the viewer.

[0249] It would be good to have a function that warns when an approaching vehicle is detected while the vehicle is stopped. If an approaching vehicle is detected while the vehicle is not stopped, it would be good to have a function that suppresses the approach warning that would normally be issued while the vehicle is in motion. Suppressing the approach warning could mean, for example, issuing a milder warning than usual, or even not issuing a warning at all.

[0250] It would be beneficial to have a function that records video footage captured by a camera, triggered by the detection that the preceding vehicle has started moving but the vehicle itself has not started moving within a predetermined time. The detection of the preceding vehicle stopping could be performed, for example, based on the size of the area that can be considered to be a vehicle in the image captured by the camera that takes pictures of the front.

[0251] When the system detects that the preceding vehicle has started moving but the vehicle itself has not started moving within a predetermined time, it triggers a recording of video footage captured by a camera. The video footage should ideally be from a camera that films the front of the vehicle. If the system is equipped with cameras that film areas other than the front, the video footage from those cameras should be recorded. The cameras filming areas other than the front could be, for example, cameras that film the interior of the vehicle, and ideally, cameras that film the driver. This allows for later review of the driver's behavior if they failed to notice the preceding vehicle starting, helping to identify the cause (e.g., being focused on the road but not noticing, or being distracted) and providing information that contributes to safer driving in the future.

[0252] The video footage recorded as a trigger when the system detects that the preceding vehicle has started moving but the system itself has not started moving within a predetermined time should cover the period before and after the trigger.

[0253] It is desirable to have a function that issues a warning when it is detected that the vehicle ahead has started moving but the vehicle itself has not started moving within a predetermined time. It is desirable to have a function that records video captured by a camera, triggered by the detection that the vehicle ahead has started moving but the vehicle itself has not started moving within a predetermined time, and more preferably, a function that records the fact that the warning was issued and the timing of the warning.

[0254] The front and rear cameras should have approximately the same number of pixels. Furthermore, the front and rear cameras should have approximately the same sensitivity characteristics. Ideally, both should use image sensors of the same model number. A function should be included to prevent overwriting of recorded video when a potential dangerous driving situation is detected. When the engine is off, the system should not perform a determination of the possibility of dangerous driving. When the engine is off, the system should not perform detection and determination processing for aggressive driving.

[0255] In the embodiments, modifications, and other configurations described above, it is preferable to utilize some elements of the configuration from devices and equipment mounted on the vehicle or other devices and equipment installed on the vehicle later. For example, as already explained, it is preferable to utilize information from the vehicle's onboard camera, but it is also preferable to utilize sensor information such as sensors mounted on the vehicle that measure the distance to the vehicle ahead or corner sensors that determine the distance to surrounding objects, or to utilize an onboard monitor mounted on the vehicle as a monitor that outputs images captured by the camera, or to use some or all of other devices and equipment installed on the vehicle later. Doing so is preferable because it is possible to reduce the number of devices and equipment installed in a limited space, for example, and to reduce the number of objects that the driver needs to visually check while driving.
