Description

The present invention relates to a device used in a mobile body and a program for operating the device used in the mobile body.

2. Description of the Related Art In recent years, drive recorders have come to be installed in moving bodies such as automobiles for the purpose of analyzing situations in the event of an accident.

A drive recorder, for example, is acquired by capturing images from a camera that captures the surroundings of the vehicle, an acceleration sensor that detects abnormalities such as sudden braking and steering to avoid collisions and accidents, and the camera. and a storage medium for storing image data.

Then, the camera constantly captures image data of the surroundings while the vehicle is running. In addition, the output from the acceleration sensor is monitored, and if the acceleration exceeds a predetermined threshold, it is assumed that an abnormality such as sudden braking or steering has occurred in order to avoid a collision accident or accident, etc. Image data for a predetermined time before and after the image data are stored in a storage medium. Video data that is constantly being shot is overwritten as time passes, but the image data saved in the storage medium is not overwritten when the acceleration exceeds a predetermined threshold and can be played back at a later date. Become.

As a result, the user can check the surroundings of the vehicle when an abnormality such as sudden braking or sudden steering occurs in order to avoid a collision or accident. An example of such a drive recorder is described in Patent Document 1, for example.

It is also conceivable to store not only the image data but also the points where the acceleration exceeds a predetermined threshold value in a storage medium. It is also conceivable to superimpose and display information indicating points where the acceleration exceeds a predetermined threshold on a map displayed by a car navigation device that provides travel guidance to a user using a mobile object.

Here, the basic functions of the car navigation system will be described as a premise for such a case.

An example of a car navigation device is described in Patent Document 2, for example. The car navigation device described in Patent Document 2 includes position detection means for detecting the current position of the own vehicle by performing positioning using a GPS (Global Positioning System), a storage unit for storing information such as road type information, and a display unit for displaying an image.

The car navigation system described in Patent Document 1 creates information for operation guidance based on the position of the destination, the current position of the own vehicle, the type of road, etc., and uses the created information for operation guidance. The map information is superimposed and displayed on the display unit.

By including an icon or the like representing the point where the acceleration exceeds the predetermined threshold in the information for operation guidance and displaying it on the map, the user can easily identify the point where the acceleration exceeded the predetermined threshold in the past. It is possible to easily grasp where it is.

JP 2013-235395 A JP 2013-160679 A

As described above, by using the functions of the drive recorder, it is possible to store and reproduce video data when an accident or the like occurs, or to store the location of the accident or the like. Furthermore, if the function of the car navigation system is also used, it is possible to display an icon or the like representing the location where the accident or the like occurred on the map.

However, in the method of detecting the occurrence of an accident, etc. using measurement information such as acceleration, it is necessary to completely eliminate the possibility of erroneously detecting that an accident, etc. has occurred even though no accident, etc. has occurred. can't. In other words, when the acceleration exceeds a predetermined threshold, it can be assumed that an accident, etc. has probably occurred. It is also possible that they are not.

Here, a case where such erroneous detection occurs will be described using a specific example.

For example, assume that there is a point on the road with a level difference with a drop of more than a certain level. Then, every time the moving object carrying the drive recorder passes through the step at that point, it receives a constant impact corresponding to the height difference of the step, and accordingly the acceleration exceeds the threshold each time it passes. As a result, it is assumed that an accident or the like has occurred at that point each time the vehicle passes through.

However, the event of simply driving over a bump is not an event that should be detected in relation to the function of the drive recorder. The events that should be detected in relation to the function of the drive recorder are, for example, events such as accidents caused by contact with other vehicles, etc., and inappropriate dangers such as sudden braking and sharp turns to avoid accidents. It is an event that driving was performed.

In other words, in light of the original intent of why video data is recorded by the drive recorder function, it is inappropriate to assume that an accident, etc., has occurred when driving on a point with steps. It can be said that it is an erroneous detection to assume that an accident or the like has occurred in this way.

In addition, in the case of erroneous detection in this way, many problems arise in relation to erroneous detection, and this point will be described below.

As a matter of course, since the capacity of a storage medium is finite, there is an upper limit to the number of pieces of video data that can be stored. Nevertheless, if unnecessary video data is saved due to erroneous detection, there arises a problem that the storage capacity of the storage medium is wasted. In relation to this, there is a problem that the video data at the time of the accident cannot be stored even though the free space of the storage medium is insufficient due to the unnecessary video data, and the correct detection is difficult. There is also a problem that the video data stored based on the data is erased by overwriting.

Furthermore, when displaying an icon or the like representing a location where an accident or the like occurred on a map as described above, an icon representing a location where an erroneous detection has been performed is also displayed. As a result, there arises a problem that the icon representing the location where the accident or the like actually occurred, which should be displayed, and the map itself become difficult to see.

Therefore, in the present invention, it is desirable to provide a device and a program capable of preventing the processing that should be performed when an accident or the like actually occurs, even though the occurrence of the accident or the like is erroneously detected. aim.

(1) A device that performs control for storing first information when a first condition is satisfied, wherein the first information is not stored due to an event that does not require storage of the first information. A device characterized by not performing control for storing the first information even if the first condition is satisfied again at a certified point that is a point where the condition is satisfied.

Thus, at a certified point, which is a point where the first condition is satisfied due to an event that does not require storage of the first information, even if the first condition is satisfied again, the first A configuration that does not store information is preferable. As a result, the amount of data to be stored can be reduced. In particular, when an event that does not require storage of the first information occurs every time at the same point, the first information is not stored every time. As a result, it is possible to prevent the storage capacity of the storage medium storing the first information from becoming full.

In particular, at points other than the certified points, the first information may be stored when the first condition is satisfied. Thereby, the first information may be stored at a point where the first condition is satisfied due to an event requiring storage of the first information. For example, an event that does not require storage of the first information does not occur at the same point every time, but the first information can be stored at points where an event that requires storage of the first information occurs. It is good because it can be done. As a result, the really necessary first information can be stored.

Moreover, it is preferable that the present device is realized by a device including the function of a drive recorder. By doing so, the device can be realized by hardware for realizing the function of the drive recorder. For example, it is preferable to operate software for realizing the function of the device by using an arithmetic processing device that performs arithmetic processing for realizing the function of the drive recorder and a storage device. Further, for example, it is preferable to determine whether or not the first condition is satisfied by using a measurement result from a sensor for realizing the function of the drive recorder. In particular, it is preferable to use an acceleration sensor as the sensor and determine whether or not the first condition is satisfied based on the acceleration measured by the acceleration sensor. Furthermore, for example, the control target of the control for storing the first information may be the control of storing information by the function of the drive recorder.

Further, the "first condition" may be predetermined information that has a predetermined pattern, and the predetermined information may be information that changes particularly with the movement of the moving body. For example, it may be assumed that "information that changes with the movement of the moving object" has a predetermined pattern. The "predetermined pattern" may be a state in which a predetermined state continues or a state having a predetermined correlation with a pre-stored pattern. It is better to In addition, when an impact caused by a mobile body involved in a collision accident or an abnormal impact such as sudden braking or sudden steering to avoid an accident is detected, It is preferable that the information that changes according to the number follows a predetermined pattern. By doing so, it is possible to store the first information when an abnormality such as sudden braking or sudden steering occurs in order to avoid a collision or accident.

Also, the "first information" may be information related to an event that causes the first condition to be satisfied. image data. By doing so, it is possible to confirm the situation inside and around the moving body when the first condition is satisfied. Furthermore, the image data used as the first information may be a still image, but may be moving images recorded before and after the first condition is satisfied, including the time when the first condition is satisfied. By doing so, it is possible to confirm not only the time when the first condition is satisfied, but also the situation before and after the first condition is satisfied.

Furthermore, the "event that does not require storage of the first information" may be an event that is not intended as an event that requires storage of the first information in light of the application of the device. By doing so, it is possible to prevent the first information from being stored even though an unintended event has occurred.

In particular, the use of this device may be to control information stored by a drive recorder. For example, it is preferable to control whether or not to store video data when the drive recorder detects an impact. In this case, for example, in the case of erroneous detection that the impact is not caused by an accident but by passing over a step, it is preferable to perform control so as not to store the video data. On the other hand, if the impact is caused by an accident or the like, control may be performed to store video data. By doing so, it is possible to prevent the memory capacity of the storage medium from becoming full. In addition, since it is possible to prevent the memory capacity of the storage medium from becoming full, it is possible to store and leave a really necessary image such as an image when an accident or the like occurs.

Furthermore, the "authorized point" may be a point recognized as a point that satisfies the first condition due to an event that does not require storage of the first information. For example, when the first condition is satisfied by the passage of a moving body at a certain point, but it is recognized that it is caused by an event that does not require the storage of the first information. , this point may be used as a certified point. The authorization of the authorized point may be performed according to the user's operation, for example. By doing so, it is possible to perform accurate authentication based not only on the criteria of whether or not the first condition is satisfied, but also on the judgment of the user.

(2) The apparatus, wherein the first condition is that measurement information that changes with movement of a mobile body on which the apparatus is mounted changes to predetermined information.

In this way, it is preferable to determine whether or not to store the first information based on the measurement information that changes with the movement of the mobile body on which this device is mounted. By doing so, the first information can be stored according to the movement status of the moving body. Furthermore, it is preferable that the present device measures information that changes as the moving body moves. By doing so, the processing can be completed by this apparatus.

Further, even if the first condition is satisfied in accordance with the movement status of the mobile object, the first information may not be stored at the certified point. As a result, the first information is not stored based only on the movement status of the mobile body.

(3) when the first condition is satisfied, storing second information that is information specifying the position of the point where the first condition is satisfied;
When the second condition is satisfied, output the second information specifying the position of the spot other than the certified spot, but do not output the second information specifying the position of the certified spot. A device characterized by:

In this way, when the second condition is satisfied, it is preferable to output information specifying a point other than the certified point where the first condition is satisfied. As a result, it is possible to identify the point where the first condition is satisfied at the output destination.

Further, in this way, it is preferable to adopt a configuration in which the information specifying the position of the certified point is not output. As a result, both the information specifying the point other than the certified point that satisfies the first condition and the information specifying the position of the certified point are output, resulting in an excessive amount of information to be output. It is good because it can prevent

"Output" may be performed by displaying, for example, on a screen that the user refers to. By doing so, the user can specify a point other than the authorized point where the first condition is satisfied. Also, in this case, the information specifying the certified point is not output on the screen that the user refers to, so it is possible to prevent the screen from becoming difficult to see.

The "second information" may be, for example, an icon displayed on the map. In this case, it is preferable to change the display mode of the icons particularly according to the degree to which the first condition is satisfied, the order in which the first condition is satisfied, or the like. For example, it is preferable to change the display mode by changing the color of the icon, changing the shape of the icon, or adding a number. By doing so, the user who refers to the map and icons can recognize the degree to which the first condition is satisfied, the order in which the first condition is satisfied, and the like.

The "second condition" may be a condition that is satisfied when it is desirable to refer to the second information at the output destination. For example, the second condition may be to display a map that the user refers to. In particular, it is better to do as described in (4) below.

(4) The device, wherein the second condition is that the device approaches a point where the first condition is satisfied.

In this way, the second condition is that the device has approached a point where the first condition is satisfied, and when the second condition is satisfied, the point where the first condition is satisfied is specified. A configuration for outputting information is preferable. As a result, the output destination can know that the first condition has been satisfied in the vicinity of the device in the past.

For example, the output may be performed on a screen that the user refers to. By doing so, the user can grasp that the first condition has been satisfied in the past in the vicinity of the current position of the device.

(5) A device characterized by outputting the second information specifying the position of the certified point when a third condition is satisfied.

In this way, it is preferable to output the second information specifying the position of the certified point when the third condition is satisfied. As a result, the position of the certified point can be specified at the output destination. For example, the output may be performed on a screen that the user refers to. By doing so, the user can specify the position of the authorized point. As a result, for example, it is possible to know in advance that an event that satisfies the first condition will occur again because the vehicle will pass through the certified point. Also, it is good because the reason why the first information is not stored even though the first condition should have been satisfied can be understood.

The 'third condition' may be a condition that is satisfied when it is desirable to refer to the position of the certified point at the output destination. For example, the third condition may be that an operation for confirming the position of the certified point has been received from the user.

(6) A device characterized in that the second information about the certified point and the second information about the point other than the certified point are displayed in different display modes.

In this way, the second information, which is the information specifying the position of the point where the first condition is satisfied, may be output in different display modes for the certified point and other points. As a result, the position of the authorized point and the position of the point satisfying the first condition other than the authorized point can be distinguished from each other by the output destination.

(7) The apparatus, wherein the certified point is determined based on a user's operation referring to the stored information when the first condition is satisfied.

In this way, it is preferable that the certified point is determined based on the user's operation. As a result, the certified point can be determined more accurately than the determination of the certified point by the automatic determination of the device. Moreover, it is not necessary to set in the device what kind of criteria are to be used for determining whether or not a point is a certified point.

Moreover, by doing so, the user determines the authorized point after referring to the stored information when the first condition is satisfied. As a result, the certified point can be determined more accurately than when the information is not referred to.

The information stored when the first condition is satisfied may be either the first information or the second information, but it is more preferable to store both because the user will have more information to make a decision.

The first information may be, for example, image data captured when the first condition is satisfied. By doing so, the user can refer to the image data and determine whether or not the point is a certified point.

The second information may be, for example, information specifying the position of the point that satisfies the first condition. By doing so, the user can grasp the position of the point that satisfies the first condition and then determine whether or not the point is a certified point.

(8) The first condition includes condition 1-1 and condition 1-2, and condition 1-1 is not satisfied due to an event that does not require storage of the first information. At the certified point certified as being satisfied, if the 1-1 condition is satisfied again, the control for storing the first information is not performed, but the 1-2 condition is An apparatus characterized by controlling to store said first information when satisfied.

In this way, even if conditions 1-1 are met again at a point that has become a certified spot after satisfying conditions 1-1 due to an event that does not require memorization of the first information, , the first information may not be stored. As a result, the amount of data to be stored can be reduced. In particular, when the same event occurs at the same point each time, it is preferable that the first information is not stored each time. For example, if there is a step, the same level of impact will occur every time the vehicle passes through this point, but it is not necessary to memorize the first information each time at such a point.

Further, in this way, even if the point becomes a certified point after satisfying the condition 1-1, if the condition 1-2 is satisfied, the first information is stored. good. As a result, even if the point is once certified as a certified point, the first information can be stored if the condition 1-2 is satisfied. In particular, even if the same event occurs every time at the same point, the first information can be stored if a different event instead of the same event occurs at the point. For example, if there is a point with a step, the same level of impact occurs every time the vehicle passes through this point, but if the impact is not of the same level but is greater, the first information can be stored. It is good because it can be done.

"Condition 1-1" and "Condition 1-2" should be more finely distinguished from the first condition. For example, if the first condition is that the measured acceleration exceeds the threshold, multiple thresholds are provided, and if the first threshold is exceeded, the condition 1-1 is satisfied. , the second threshold, which is a larger value than the first threshold, is also exceeded, it is preferable that the condition 1-2 is satisfied. By doing so, in the event that an accident or the like occurs at the certified point and an impact greater than the impact that is always detected due to the step at the certified point occurs, the first information can be stored. It's good because you can do it.

(9) The first condition includes a plurality of conditions in stages according to the size of the threshold, and when the conditions are arranged in order from the smallest threshold, the condition 1-2 is , a condition following the condition 1-1, or a condition following the condition following the condition 1-1.

In this way, when either the condition following the condition 1-1 or the condition following the condition after the condition 1-1 is satisfied in ascending order of the threshold value, the first information is stored. should be controlled. As a result, even though the 1-2 condition, which is the next order of the 1-1 condition, was satisfied at the point that was designated as a certified location because the 1-1 condition was satisfied, This is good because it can prevent a situation in which the first information is not stored.

For example, when the conditions are arranged in ascending order of threshold value, n conditions are arranged such as condition 1, condition 2, condition 3, . . . condition n. Then, even if the condition 1 is satisfied again, the first information is not stored at the point determined as the certified point because the condition 1 is satisfied. This is because only the condition 1 is satisfied each time due to the difference in level at the certified point, and no particular accident or the like has occurred. In addition to this, it is conceivable not to store the first information even if the condition 2 or the condition 3 is satisfied, for example. However, if the first information is not stored for all the conditions that are set step by step, the first information is not stored even though the first information should be stored. Situation may occur. For example, consider a case where, due to an accident or the like, condition 2, which has a higher threshold value, is satisfied instead of condition 1, which is satisfied every time due to a step at a certified point. In this case, since an accident or the like has occurred, it is preferable to store the first information. Therefore, if at least condition 2 is satisfied, it is preferable to allow the first information to be stored.

(10) The first condition includes a plurality of conditions in stages according to the magnitude of the threshold, and when at least the condition with the highest threshold is satisfied, even if the certified point is the A device, characterized in that it stores first information.

In this manner, if the condition with the highest threshold among multiple conditions corresponding to thresholds is satisfied, the first information may be stored regardless of whether or not the point is a certified point. This can prevent a situation in which the first information is not stored even though the condition with the highest threshold is satisfied.

When a plurality of thresholds are provided, even if an impact that exceeds the highest threshold occurs, it is conceivable not to store the first information if it is a certified point. However, if this is done, the first information will not be stored even if a significantly large impact occurs. It is considered that the occurrence of such a remarkably large impact is caused by an accident or the like. Therefore, it is preferable to store the first information. Therefore, as described in (10), it is preferable to store the first information when the highest threshold is exceeded.

(11) A device characterized in that the authorized point is defined by a distance range representing the authorized point and a passing direction when passing through the authorized point.

In this way, it is preferable to define the authorized point not only by the distance range but also by the passing direction when passing through the authorized point. By doing so, it is possible to determine that the vehicle is in the defined certified point when it enters the distance range of the certified point from a certain direction. On the other hand, if the vehicle intrudes into the distance range of the certified point from another direction, it can be determined that the vehicle is not within the defined certified point.

For example, the first condition is satisfied each time the distance range of the certified point is intruded from a certain direction, but the first condition is satisfied every time the distance range of the certified point is intruded from another direction. At a point where condition 1 is not satisfied, the configuration described in (11) may be used. This is because it is preferable to determine that a spot where the first condition is satisfied every time is a certified spot and not record the first information even if the first condition is met.

For example, it is assumed that one lane of a two-lane road (assumed to be an up lane) has a step, and the other lane (assumed to be a down lane) does not have a step. In this case, when the vehicle intrudes into the distance range of the certified point from the up-lane, a constant impact is generated each time due to passing through the step. Therefore, in this case, it is preferable not to store the first information as passing through the certified point. On the other hand, when the vehicle intrudes into the distance range of the certified point from the down lane, there is no step, so normally no impact occurs. If an impact occurs, it is considered that it is caused by an accident or the like. Therefore, in this case, it is preferable to store the first information as not passing through the certified point. Therefore, in consideration of the case where it is necessary to change whether or not to be stored depending on such a passing direction, as in (11) above, the authorized point is not limited to the distance range, but the authorized point is passed through. It is preferable to make it possible to determine whether or not the certified point has been passed after defining it according to the passing direction at the time.

(12) If the first condition is satisfied continuously at a plurality of points at intervals less than a predetermined time interval, and if all of the plurality of points are certified points, the plurality of certified points A device characterized by outputting information specifying the position of one group, rather than information specifying the position of each of the plurality of certified spots, with the spots being one group.

In this way, if the points satisfying the first condition are consecutive and each of these points is a certified point, these points are regarded as one group, and the position of one group is specified. It is preferable to have a configuration in which information to be displayed is output. Also, in this way, it is preferable to adopt a configuration in which a plurality of pieces of information specifying respective positions of a plurality of points are not output.

By doing so, at the output destination, information specifying the position of one group may be output instead of outputting each of the information specifying a plurality of points. For example, the output destination may be the screen that the user refers to. By doing so, it is possible to prevent the screen from becoming difficult to see due to all of the information specifying the positions of the plurality of points being displayed. Also, information specifying the positions of each of the plurality of points is not displayed, but information specifying the position of one group is displayed, so that the user can grasp that there are a plurality of certified points at that position. good.

There are roads that are continuously provided with steps for the purpose of suppressing the traveling speed and alerting the driver of the moving object by giving sound and vibration to the driver. When passing through such a road, the first condition is continuously satisfied. However, if information for specifying each point is output for each point that satisfies the first condition, the amount of information to be output increases. Therefore, by treating each of these points as one group and outputting information specifying the position of one of these groups, it is possible to prevent the output information from becoming unnecessarily large.

(13) A point that has been certified as the above-mentioned certified point when a predetermined time has passed since it was certified as the above-mentioned certified point, or when the number of the above-mentioned certified points has reached a predetermined number, or in both cases. is not treated as the certified point.

In this way, it is preferable to adopt a configuration in which a point is not treated as a certified point when a predetermined period of time has passed since it was certified as a certified point. By doing so, it is possible to always keep the number of authorized points below a predetermined number.

This is good because it is possible to prevent the number of certified points from becoming enormous. If the number of certified points becomes enormous, when outputting the information specifying the positions of the certified points, a large number of certified points will be output. It is preferable to prevent it from being put away.

In particular, if the device is to be used continuously for a long period of time, the number of authorized points will increase as the period of use increases.

(14) A device characterized by not treating the certified point as the certified point if the first condition is not satisfied even after passing through the certified point.

In this way, if the certified spot is certified as a certified spot, but if the first condition is not satisfied despite passing through the certified spot, the certified spot will not be treated as the above-mentioned certified spot. good. As a result, a point that should no longer be an authorized point is not treated as an authorized point.

For example, it is assumed that there is a step at a certain point, so that an impact that satisfies the first condition is generated every time the vehicle passes through. In this case, let this certain point be a certified point. However, if the situation changes and, for example, there is no step, the shock that satisfies the first condition will not occur even if the certain point is passed. In such a case, it is better not to treat this certain spot as a certified spot. This is because although it was certified as a certified spot because it satisfies the first condition every time it passes through, the situation has changed, and it has become a spot that does not satisfy the first condition even if it passes through. .

(15) A drive recorder function and a car navigation function are provided, the first information is image data captured by the drive recorder function, and the image data captured by the drive recorder function does not need to be stored. A point that satisfies a first condition is defined as the certified point, and information specifying the position of a point that satisfies the first condition and is other than the certified point is displayed on the map displayed by the car navigation function. A device characterized by displaying on.

In this way, it is preferable to store the image data captured by the drive recorder function when the first condition is satisfied. As a result, even after the first condition is satisfied, the image data captured by the drive recorder function can be used. "Image data captured by the drive recorder function" is, for example, an image of the surroundings of a moving object captured when the moving object equipped with this device receives a certain amount of impact due to contact with another object. should be converted into data.

In this way, at a certified point, which is a point where the first condition is satisfied due to an event that does not require storage of image data captured by the drive recorder function, the image data captured by the drive recorder function is stored. It is preferable to have a configuration in which no memory is stored. Accordingly, it is possible to prevent image data caused by an event that does not require storage of image data from being stored each time a certified point is passed. An event that does not require storage of image data may be, for example, that a moving body on which the device is mounted has passed a step. Satisfaction of the first condition due to an event that does not require storage of image data may be, for example, detection of an impact when a moving body on which the device is mounted passes through a step. .

Furthermore, in this way, when the information specifying the position of the point that satisfies the first condition is displayed on the map displayed by the car navigation function, the information specifying the position of the certified point is not displayed. good. As a result, it is possible to prevent more information than necessary from being displayed on the map. "Display information specifying the position of the point that satisfies the first condition on the map displayed by the car navigation function" means, for example, specifying the position of the point that satisfies the first condition on the map. It is better to display the icon.

(16) A program that causes a computer to function as the device according to any one of (1) to (15) above.

Thus, by making a computer function as the device described in any one of (1) to (15) above, all or at least one of the functions of the device described in (1) to (15) above can be performed. It is good because it becomes possible to realize the part by a computer.

Furthermore, the first control unit 100 communicates with an external device connected via the USB terminal 320 .

Touch panel 110 accepts an operation when the screen is pressed by the user, and outputs the contents of the accepted operation to first control unit 100 . Here, the content of the operation is information that specifies the position on the screen of touch panel 110 at which the depression was accepted. Also, the touch panel 110 displays image data input from the first control unit 100 on the screen. Further, touch panel 110 displays image data input from TV tuner 150 on the screen.

The speaker 120 outputs sounds such as music and voice input from the first control unit 100 .

The notification LED 130 lights up or flashes under the control of the first control unit 100 .

A button 140 is a physical button 140 provided on the housing of the integrated device 1000 and receives a user's operation.

Here, when the integrated device 1000 is installed in a vehicle and used as described above, the touch panel 110, the speaker 120, and the notification LED 130 are configured so that the user can output the touch panel 110, the speaker 120, and the notification LED 130. Placed in a detectable position. Also, the touch panel 110 and the buttons 140 are arranged at positions where they can be operated by the user.

TV tuner 150 receives a TV signal, converts the received TV signal into image data in a predetermined format, and outputs the image data to touch panel 110 . In the following description, the image data converted by the television tuner 150 will be referred to as "television video".

GPS sensor 160 measures the current position of all-in-one device 1000 using GPS, and outputs the measured position information to first control unit 100 . Here, the positional information is realized by, for example, coordinate information conforming to the GPS standard.

The acceleration sensor 170 measures acceleration and inputs the measured acceleration to the first control unit 100 . Note that the acceleration sensor 170 is sometimes called a "G sensor".

The first storage unit 180 is a part into which a removable storage medium is inserted by the user. In the first storage unit 180, for example, a storage medium storing music files in MP3 (MPEG-1 AudioLayer-3) format and television images written by the first control unit 100 is inserted. Under the control of first control unit 100 , these music files and television images are read from the storage medium inserted in first storage unit 180 and output from speaker 120 and touch panel 110 .

The main storage unit 190 stores information for performing car navigation. Specifically, map information, information on certain landmarks, information for specifying the type of road, information on facilities, address information, and the like are stored. Further, the main storage unit 190 stores software for realizing control by the first control unit 100 .

Also, the software in the main storage unit 190 can be updated using the latest data of the software updated after the shipment of the integrated device 1000, the latest data of the target, and the like. For example, a storage medium storing the latest data is inserted into the first storage unit 180 , and the first storage unit 180 reads additional data from this storage medium and updates the software in the main storage unit 190 . Here, the main storage unit 190 is realized by, for example, a flash memory.

Further, when the integrated device 1000 is installed in a vehicle and used as described above, the current position measured by the GPS sensor 160 represents the current position of the vehicle, and the acceleration measured by the acceleration sensor 170 represents the vehicle's current position. It represents the acceleration. Then, the first control unit 100 compares the current position measured by the GPS sensor 160 with the map information stored in the storage unit to create a map for operation guidance including the current position of the vehicle. , the map for operation guidance is displayed on the touch panel 110 . Also, the touch panel 110, the speaker 120 and the notification LED 130 are used to output predetermined information, alarms and messages. The car navigation function is realized by the first control unit 100 performing these processes.

On the other hand, the second control unit 200 particularly controls the camera 210, the microphone 220, and the second storage unit 230 among the units described above.

The second control unit 200 receives a video signal captured by the camera 210 and an audio signal collected by the microphone 220, converts the input video signal and audio signal into image data in a predetermined format, and stores the data. store in In the following description, the image data converted by the second control unit 200 will be referred to as "real-time video".

Second control unit 200 also outputs the real-time video to first control unit 100 . The output real-time video is displayed on touch panel 110 .

Camera 210 includes an incident portion 211 .

Furthermore, the microphone 220 collects sounds. A sound collected by the microphone 220 is converted into an acoustic signal and output to the second control unit 200 .

Here, when the integrated device 1000 is installed in an automobile and used, the light incident on the incident part 211 and the sound collected by the microphone 220 are objects to be imaged by the drive recorder. Here, the target to be imaged by the drive recorder is, for example, scenery in the traveling direction and surrounding sounds imaged through the windshield from inside the vehicle. Then, the second control unit 200 realizes the function of the drive recorder by storing the object to be imaged by the drive recorder in the second storage unit 230 in a predetermined video format.

The power supply unit 310 supplies power to each functional block included in the integrated device 1000 . Power is supplied to the power supply unit 310 from an external device via the USB terminal 320 . In FIG. 1, wiring for supplying power from the power supply unit 310 to each functional block is omitted.

The USB terminal 320 is a terminal conforming to the USB standard. The USB terminal 320 is connected to an external device via a cable conforming to the USB standard. Power is supplied from the external device via a cable. It is also possible to communicate between the first control unit 100 and an external device via a cable.

Here, when the integrated device 1000 is installed in an automobile and used, a cable connected to the car charger of the automobile is connected to the USB terminal 320 . The integrated device 1000 is then powered by the vehicle's car charger.

The functional blocks of the present embodiment have been described above.

Note that the first control unit 100 and the second control unit 200 described above are each implemented by an arithmetic unit such as a CPU (Central Processing Unit), a RAM (Random Access Memory), a ROM (Read only memory), or the like. be. The control by the first control unit 100 and the second control unit 200 is realized by the CPU reading the software stored in the ROM or the main storage unit 190 and executing arithmetic processing while developing the software in the RAM.
<Processing of this embodiment>
Next, each of the processes performed by this embodiment will be described in detail with reference to the drawings.
<Real-time video recording>
First, real-time video recording performed under the control of the second control unit 200 will be described with reference to FIG. In this embodiment, there are three recording methods: constant recording, manual recording, and event recording.

First, as a premise, imaging is performed when the engine of the automobile in which the integrated device 1000 is installed is started, and real-time image acquisition is started. Then, when the engine of the automobile is stopped, the imaging ends, and the acquisition of the real-time video ends accordingly.

Here, whether or not the engine of the automobile is operating may be determined according to whether or not power is supplied from the automobile via the USB terminal 320, for example. In other words, acquisition of real-time video is started when power supply is started, and acquisition of real-time video is ended when power supply is stopped.

Next, constant recording will be described. The real-time video is stored in the second storage unit 230 from the start of acquisition of the real-time video to the end of acquisition of the real-time video. In other words, recording is always performed while the car engine is running.

The recorded real-time video is divided into a plurality of files in units of a predetermined length and stored in the second storage unit 230 . Although the unit of the predetermined length is arbitrary, for example, one file may be set in units of 30 seconds. Note that this file will be referred to as a "video file" in the following description.

Until the capacity of the second storage unit 230, which is allocated for constant recording, becomes full, as shown in the upper left of FIG. Saving of the video file continues. Although the capacity to be allocated for constant recording is arbitrary, it is preferable to set it to a capacity capable of recording a video file corresponding to a length of 20 minutes, for example.

In addition, even after the capacity of the second storage unit 230, which is allocated for constant recording, is full, the storage of the video file continues. However, as it is, the capacity is insufficient and new video files cannot be saved. Therefore, when saving a new video file, it is better to delete the oldest video file first.

Next, manual recording will be described. Manual recording is performed by the second control unit 200 when the user's pressing of the button 140 or pressing of the touch panel 110 is detected. Specifically, when the first control unit 100 detects that the user has pressed the button 140 or touched the touch panel 110, the first control unit 100 instructs the second control unit 200 to perform manual recording. Upon receiving such an instruction, the second control unit 200 protects the video file including the point at which the pressing of the button 140 or the pressing of the touch panel 110 is detected and the video file immediately preceding that video file. In other words, two video files are protected by pressing once. Here, protecting means that the protected video file is excluded from deletion of the oldest video file by continuous recording.

Then, the two protected video files, the date and time when the manual recording was performed, and the position information specifying the position of the point where the two video files were captured are linked and stored in the second storage unit 230 as a set. An identifier must also be added to the set to identify this manual recording. For example, the date and time of manual recording may be used not only for checking the date and time, but also as an identifier. As the position information, it is preferable to request the first control unit 100 for the coordinate information measured by the GPS sensor 160, and use the coordinate information transmitted from the first control unit 100 in response to the request. Alternatively, when the first control unit 100 instructs execution of manual recording, coordinate information may also be transmitted, and the second control unit may use the transmitted coordinate information.

Furthermore, the second control unit 200 notifies the first control unit 100 that manual recording has been performed. Specifically, the fact that the manual recording was performed, the date and time when the manual recording was performed, and the location information specifying the position of the point where the manual recording was performed are linked to form a set, and this set and the current manual recording are specified. Identifiers for doing so are transmitted to the first control unit 100 . Then, the first control unit 100 stores the received paired information and its identifier in the main storage unit 190 .

The number of cases that can be protected may be arbitrarily determined according to the capacity of the second storage unit 230. For example, the maximum number of cases may be 10, that is, the capacity may be 20 video files. In the state where 20 video files are protected, when it is detected that the user has pressed the button 140 and new manual recording is executed, and when newly executing event recording, which will be described later, the oldest Two video files, which are video files for one case, are excluded from protection targets and deleted. This allows new video files to be protected.

Next, event recording will be described. When the first control unit 100 determines that an event has occurred, the second control unit 200 executes event recording. Here, an event is an event for which real-time video should be recorded. In other words, it is determined that an event has occurred when an event for which real-time video should be recorded occurs. In addition, events that should be recorded in real time include, for example, collisions that should be recorded by the function of the drive recorder, and abnormalities such as sudden braking and steering to avoid accidents. is. However, events such as collision accidents and abnormalities such as sudden braking and sudden steering to avoid accidents are only examples of events, and these events may not be treated as events. Other phenomena may be handled as events.

Then, when it is determined that an event has occurred by the first control unit 100, the date and time when the event occurred and the location information specifying the position of the point where the event occurred are linked together to form a pair, and this pair and the current event are generated. is stored in the main storage unit 190 for identifying the event recording.

When the first control unit 100 determines that an event has occurred, the fact that the event has occurred, the date and time of the event occurrence, and the location information specifying the location of the event occurrence point are combined. , the first control unit 100 notifies the second control unit 200 of this pair and an identifier for specifying this event recording. The second control unit 200 having received such notification executes event recording. How the first control unit 100 determines that an event has occurred will be explained after the explanation of this event recording.

The second control unit 200 that executes event recording protects the video file including the point in time when the event occurred and the video file that precedes the video file. In other words, two video files are protected in response to one occurrence of an event.

Then, the two protected video files, the date and time when the event occurred, and the location information specifying the location where the two video files were captured are linked together to form a set, and this set and the recording of the event this time are specified. The identifier is stored in the second storage unit 230. FIG. As with manual recording, the date and time when an event occurred may be used as an identifier. Furthermore, as for the position information, it is preferable to use the coordinate information transmitted from the first control unit 100 as in the case of manual recording.

As with manual recording, the number of cases that can be protected may be arbitrarily determined according to the capacity of the second storage unit 230. It is good to set it as the capacity|capacitance for 20 pieces. As with manual recording, when 20 video files are protected and you want to record more, remove the 2 video files, which are the video files for the oldest incident, from the protection target. should be deleted by

The video file recorded in this manner is made reproducible according to the user's operation. For example, as shown in FIG. 3, a list is displayed on the touch panel 110 using the date and time when the protected video file was captured as an identifier. Then, the touch panel 110 receives the selection by the user, and reproduces the video file corresponding to the selection on the touch panel 110 . In order for the user to be able to distinguish between manual recording and event recording, manual recording is indicated by an icon such as i1 in FIG. 3, and event recording is indicated by i2 in FIG. I am trying to attach an icon like this.

<Determination of event occurrence>
In this embodiment, the first control unit 100 determines that an event has occurred.

In order to determine that this event has occurred, the acceleration measured by the acceleration sensor 170, which is measurement information that changes as the vehicle moves, and a predetermined threshold value are used. Then, when the measured acceleration exceeds this predetermined threshold, it is determined that an event has occurred. By doing so, it is possible to detect that the automobile has collided with another moving object or installed object, or that there has been a sudden stop, a sudden transmission, or a sudden turn based on the driving of the user who operates the automobile, that is, an event has occurred. can be determined.

Moreover, a plurality of thresholds are provided stepwise instead of only one. By judging which of the stepped thresholds the measured value of the acceleration sensor 170 exceeds, it is possible to determine not only whether the vehicle has collided with another moving object or installed object, but also the impact of the collision. It is also possible to determine to what extent

For example, the threshold for the most sensitive stage is set to 0.5 G, and the sensitivity is gradually decreased from there. So the threshold for the second least sensitive stage is 0.8G, the threshold for the middle stage is 1.1G, the threshold for the second least sensitive stage is 1.4G, the threshold for the most insensitive stage is 1.7G, and so on. , is set stepwise, for example, in five steps.

If the measured value of the acceleration sensor 170 is, for example, less than 0.5G, it is not determined that an event has occurred. Also, if the measured value of the acceleration sensor 170 is, for example, 0.9G, it exceeds the threshold value of the second least sensitive stage, so it is determined that a level 2 event has occurred. Further, for example, if the measured value of the acceleration sensor 170 is 1.9 G, for example, it exceeds the threshold of the most insensitive stage, so it is determined that a level 5 event has occurred. Thus, the higher the measured value of the acceleration sensor 170 is, the higher the level of the event is determined to have occurred. In other words, the higher the level of the event, the greater the impact detected.

When it is determined that an event has occurred, the first control unit 100 associates position information for specifying the position where the event occurred, the level of the event that occurred, and the date and time that the event occurred as a set. , and the identifier for specifying this event are stored in the main storage unit 190 . Also, in the same manner as the second control unit 200 performs manual recording and event recording, it is preferable to use the date and time when an event occurs as an identification code for identifying each event. .

Further, when the first control unit 100 determines that an event has occurred as described above, the second control unit 200 executes event recording. Specifically, when the first control unit 100 determines that an event has occurred, the second control unit 200 is notified to that effect. The second control unit 200 having received such notification executes event recording. The method of executing event recording by the second control unit 200 is as described above in the section <Recording of real-time video>.

Furthermore, when it is determined that an event has occurred, the first control unit 100 notifies the user of the occurrence of the event by lighting or blinking the notification LED 130 . In addition, the first control unit 100 pops up a message such as “**** event has occurred” on the touch panel 110 .

For example, pop up a message on the map when using the navigation function. A display example of this message is shown in FIG.

First, as shown in FIG. 4, a map for operation guidance is displayed on the entire touch panel 110 . A message i3 shown in FIG. 4 is popped up to indicate the occurrence of an event. "****" of this message indicates, for example, the level of the event that occurred. For example, it is preferable to display such as "an event of level 3 has occurred". Also, such messages are urgent and should be promptly communicated to the user. That is, it is highly important as information to be conveyed to the user. Therefore, when a function other than the navigation function is used, for example, even during playback of television images, it is preferable to display a pop-up message on the television images.

An area i4 shown in FIG. 4 is provided with an area in which various types of information used for operation guidance are displayed. In the example shown in FIG. 4, the current time acquired from the GPS satellites, the reception strength and direction of the GPS signal, a value representing the scale of the map, and shortcut buttons are arranged in this area from the top.

Here, the shortcut button is a button for switching the information displayed on the screen each time it is pressed. Switching of information displayed on the screen in response to pressing of the shortcut button, that is, transition of the screen will be described later, so a detailed description thereof will be omitted here.

Further, in i5 shown in FIG. 4, the current running speed of the vehicle in which the integrated device 1000 is installed is displayed as speed per hour.

Also, in i6 shown in FIG. 4, information related to the point where the vehicle in which the integrated device 1000 is installed is currently traveling is displayed. The information related to the current point of travel includes, for example, the address, road name, latitude and longitude of the point of travel. It is also possible to display the menu screen when i6 shown in FIG. 4 is pressed.

<False detection certified point>
Next, a description will be given of recognition of falsely detected recognized points, which is a process unique to this embodiment.

As described above, the integrated device 1000 of this embodiment includes both the function as a drive recorder and the function as a car navigation device. Then, it is determined whether or not an event has occurred by functioning as a drive recorder. Also, when it is determined that an event has occurred, event recording is executed. Furthermore, an icon or the like for specifying the position of the point at which the event is determined to have occurred is displayed on the map displayed by the function as a car navigation device.

Here, as described in the above section <Event Occurrence Determination>, in the present embodiment, it is determined that an event has occurred when the measured value of the acceleration sensor 170 exceeds a predetermined threshold value. In other words, determination is made based on the premise that the fact that the measured value of the acceleration sensor 170 exceeds a predetermined threshold means that an event has occurred.

However, determination based on such assumptions is not always correct, and even if the measured value of acceleration sensor 170 exceeds a predetermined threshold, there may be cases where an event does not actually occur. In other words, it is conceivable that the occurrence of an event may be erroneously detected even though no event has occurred.

Various cases are conceivable as the cause of such erroneous detection. For example, there is a step on the road. When there is a level difference of a certain height or more at a certain point on the road, a certain impact is generated every time the automobile passes through the certain point. Therefore, every time the automobile passes through the certain point, the measured value of the acceleration sensor 170 exceeds a predetermined threshold value, and the occurrence of the event is detected by the first control unit 100 .

In addition, even if it is not a step, for example, if the road has a sharp curve, the vehicle makes a sharp turn every time it passes through the curve. Therefore, it is conceivable that the measured value of the acceleration sensor 170 exceeds a predetermined threshold value and the occurrence of an event is detected by the first control unit 100 .

However, it is considered undesirable to determine that an event has occurred and execute event recording simply because the vehicle has passed through a step or made a sharp turn that is unavoidable due to the structure of the road.

This is because, in light of the function of the drive recorder, events that should be handled as events are, for example, the occurrence of a collision accident, and abnormal operations such as sudden braking and steering to avoid accidents. This is because the phenomenon is

On the other hand, the event of simply passing over a bump, or the event of making a sharp turn that is unavoidable due to the structure of the road, should not be treated as an event in light of the function of the drive recorder. In spite of this, if it is erroneously detected that an event has occurred, unnecessary real-time video will be recorded along with the execution of event recording. As a result, the storage capacity of the storage medium inserted in the second storage unit 230 becomes full, and there is a possibility that the images of the collision accident or the like that are really required will not be retained. In addition, an icon for specifying the position of the erroneously detected point is displayed on the map, making the map difficult to see.

Therefore, in the present embodiment, it is determined that an event to be treated as an event has occurred based on the measurement result of the acceleration sensor 170. However, the determination is erroneous, and an event to be treated as an event actually occurred. The points that do not are certified as "false detection certified points". Then, information specifying the position of the erroneously detected certified point is stored in the main storage unit 190, for example. Then, even if the measured value of the acceleration sensor 170 exceeds the predetermined threshold when passing through the erroneously detected certified point again, it is not treated as occurrence of an event. As long as it is not considered that an event has occurred, no event recording is performed.

This prevents the storage medium inserted in the second storage unit 230 from becoming full. Therefore, it becomes possible to store and leave a really necessary image of a collision accident or the like.

Also, as long as it is not considered that an event has occurred, the icon for specifying the position of the point where the event has occurred is not displayed on the map. Therefore, every time the vehicle passes through the erroneously detected certified point, a new icon for specifying the position of the point where the event occurred is not displayed, and the map can be prevented from becoming difficult to see.

Next, how to certify the erroneously detected certifying point will be described.

In this embodiment, the user can determine whether the detection of the event was an appropriate detection caused by an event such as a collision accident or an erroneous detection caused by an event such as simply passing a step. based on the acceptance of

Here, the reason why the determination is made based on the reception of the user's operation is that it is necessary to avoid misjudgment as to whether or not it is a certified point for safety reasons. This is because, if an erroneous detection is made as a certified point by mistake, if an accident or the like occurs at that erroneously detected certified point, the event will not be detected and event recording will not be performed. It is from.

In order to avoid such erroneous determination, in the present embodiment, instead of automatically determining whether or not the integrated device 1000 is an erroneously detected certified point in light of a predetermined standard, such an automatic determination is performed. The erroneously detected certified point is certified based on the user's judgment which is considered to be more reliable than the above.

Next, the processing when the erroneously detected certified point is actually certified will be described with reference to the flowchart of FIG.

First, it is assumed that the vehicle equipped with the integrated device 1000 has passed through a point with a step while the operation for recognizing the erroneously detected recognized point has not been received (No in step A1). Then, the first control unit 100 determines that an event has occurred because the measured value of the acceleration sensor 170 has exceeded a predetermined threshold value, as described in <Determination of occurrence of event> (Yes in step A2). ). Then, it is assumed that the point with this step is not recognized as an erroneously detected recognized point (No in step A3).

Then, processing associated with event detection is executed (step A4).

As processing associated with event detection, the first control unit 100 first instructs the second control unit 200 to perform event recording. In response to this instruction, the second control unit 200 executes event recording. Specifically, two video files related to this event, the date and time when the event occurred, and location information specifying the position of the point where the two video files were captured are linked to form a set, and this set and the current event are linked. An identifier for specifying is stored in the second storage unit 230 . Also, like i3 shown in FIG. 4, a pop-up message indicating that an event has occurred is displayed on the touch panel 110. FIG. Further, the first control unit 100 associates the location information for specifying the position where the event occurred, the level of the event that occurred, and the date and time that the event occurred as a set, and identifies this set and the current event. The identifier for the purpose is stored in the main storage unit 190 .

In other words, even at a point with a step that should be recognized as an erroneous detection recognition point, if it is not yet recognized as an erroneous detection recognition point, recording processing, which is processing associated with event detection, is performed as usual. , screen display processing and storage processing of position information and the like are executed.

However, if no collision has actually occurred and no sudden braking or other operation has been performed to avoid an accident, the user can immediately determine that such event detection is an erroneous detection. .

Also, even if it cannot be judged on the spot, the user can judge that the detection of such an event is an erroneous detection by referring to the real-time video recorded by the event recording afterwards. Further, even if the event cannot be determined by detecting the event once, the user can determine that the detection of the event at the point is an erroneous detection because the event is detected each time the point is passed.

When the user thus determines that an event has been detected erroneously, the user performs an operation for certifying that the point where the event was detected is an erroneously detected authorized point. Integrated device 1000 accepts this user's operation via touch panel 110 and button 140 (Yes in step A1).

When the operation is accepted, the details of the accepted operation are input to the first control unit 100 . Then, the first control unit 100, which has received the operation details, performs processing for certifying that the point where the event was detected is a point where erroneous detection occurs, that is, an erroneously detected authorized point (step A5). Specifically, the date and time when an event occurred at a false positive recognition point and the location information that specifies the location of the false positive recognition point are linked together, and this group and the identifier for identifying this false positive recognition point are mainly used. Stored in the storage unit 190 .

After that, even if the measured value of the acceleration sensor 170 exceeds the predetermined threshold value (Yes in step A2), the first control unit 100 determines that the point is an erroneously detected certified point (Yes in step A3). ), the event is treated as not having occurred. Therefore, even if the measured value of the acceleration sensor 170 exceeds the predetermined threshold value, the process does not transition to step A4. In other words, recording processing, screen display processing, and storage processing of position information, etc., which are processing associated with event detection, are not executed.

After that, the monitoring of A1 and A2 is continued until there is a recognition operation of a falsely detected recognition site with respect to another site or a new event is detected (No in step A1 and No in step A2).

As described above, by performing the processing with reference to FIG. 6, the erroneously detected certified point can be certified.

Then, even if the acceleration value exceeds the threshold value at the erroneous detection certified point, it is treated as if no event has occurred. No processing is performed.

This prevents the storage medium inserted in the second storage unit 230 from becoming full. Therefore, there is an effect that it becomes possible to store and leave a really necessary image of a collision accident or the like.

Also, as long as it is not considered that an event has occurred, the icon for specifying the position of the point where the event has occurred is not displayed on the map. As a result, a new icon will no longer be displayed to identify the location of the location where the event occurred each time you pass through a certified false detection location, preventing the map from becoming difficult to read. Effective.

On the other hand, if the acceleration value exceeds the threshold value at a point other than the false detection certified point, it is treated as if no event has occurred, and processing associated with event detection, such as recording processing and screen display processing. and memory processing of position information and the like.

Therefore, event recording can be performed when an accident or the like actually occurs. In relation to this, as described above, event recording is not performed at false detection certified points, so even if an accident or the like actually occurs, the storage capacity of the storage medium will already be full. There is an effect that it becomes possible to prevent such a situation.

In addition, when an accident or the like actually occurs, an icon for identifying the location of the accident or the like is displayed, making it possible to identify the location where the accident or the like occurred. In relation to this, since the icon of the erroneously detected certified point is not displayed, it is possible to easily visually recognize the icon for specifying the position of the point where the accident or the like occurred.

The basic contents of the recognition of falsely detected recognition points have been described above. Modifications related to falsely detected certified points will be described below.

As described in the section <Determination of Occurrence of Event> above, in order to determine that an event has occurred, the acceleration measured by the acceleration sensor 170, which is measurement information that changes as the vehicle moves, and a predetermined is used, but not only one but a plurality of thresholds are provided step by step.

Therefore, it is conceivable to use the plurality of thresholds for certifying falsely detected certifying points as well.

For example, it is assumed that points exceeding the threshold of level 1, which is the threshold of the most sensitive stage, are designated as erroneously detected points. In this case, as explained in step A3 above, even if the occurrence of an event is detected when passing through the erroneous detection certified point, this is regarded as an erroneous detection, and the event is treated as not having occurred. (Yes in step A3).

However, it is conceivable to modify this. Specifically, if the level 1 threshold, which is the threshold for the most sensitive stage, is exceeded when passing through this false detection certified point, it is considered to be a false detection, but it is a stage that is less sensitive than level 1. When the threshold of level 2 or higher, which is the threshold of , is exceeded, it can be considered that an event has actually occurred instead of an erroneous detection.

The reason for doing so will be explained. If there is a step with a certain height difference, a certain impact corresponding to the height is generated every time the step is passed. Therefore, in the present embodiment, that point is recognized as an erroneously detected certified point, and thereafter, it is assumed that no event has occurred at the erroneously detected certified point.

However, when passing through the step, if a larger impact than the impact caused by the drop of the step occurs, the impact is considered to have occurred regardless of the step. In other words, it is considered that the impact was caused by the occurrence of an accident or the like unrelated to the step. In such a case, event recording should be performed to store video data before and after the occurrence of an accident or the like, even if the location is a falsely detected spot.

Therefore, as described above, for example, when a point exceeding the threshold of level 1 is set as a false detection certified point, if the threshold of level 2 or higher, which is a more insensitive level than that, is exceeded, it is not a false detection, but an actual , the event is treated as having occurred, and processing associated with the event detection is executed (step A4).

By transforming in this way, when an accident or the like actually occurs at a false detection certified point, event recording is performed, and video data before and after the occurrence of the accident or the like can be stored. It has the effect of

On the other hand, if only the same degree of impact occurs each time at a false detection certified point, processing such as storing video data before and after the occurrence of an accident, etc. is not performed, so unnecessary video data is stored. There is an effect that it is also possible to prevent this.

In the above description, when a point exceeding the threshold of level 1 is set as a false detection certified point, when the threshold of level 2 or higher, which is a less sensitive level than that, is exceeded, the process associated with event detection is executed. This is just an example. In addition, when a point exceeding the threshold of level 2 is regarded as a false detection certified point, if the threshold of level 3 or higher, which is a more insensitive level than that, is exceeded, the process associated with event detection is executed. good too.

In addition, when a point exceeding the level 1 threshold is designated as a false detection certified point, not only the level 1 but also the level 2 threshold is exceeded, the process associated with event detection is not executed, and the level 3 or higher It is also conceivable to execute processing associated with event detection when the threshold is exceeded. In other words, it is conceivable to configure such that the process associated with event detection is not executed unless it is at a level two or more away, not at a level one level higher. Even if the step is the same, if the passing speed is different, the magnitude of the impact will also change. Therefore, even if the level is the same level or one level higher, the process associated with event detection is not executed. That's what it means. This eliminates the need to perform the erroneously detected certified point certification process again when the threshold of the level one level above is exceeded due to the same step.

However, in this case, if an accident or the like occurs due to an impact that exceeds the threshold value of one level higher, the processing associated with the event detection is executed regardless of the occurrence of the accident or the like. It is also conceivable that the video data in the event of an accident or the like may not be stored. Therefore, considering that video data in the event of an accident or the like should be reliably stored, it is preferable not to execute the process associated with event detection unless the level is two or more away. After the point where the level 1 threshold is exceeded when passing through a step is designated as a false detection certified point, if the level 2 threshold is exceeded for reasons such as the difference in passing speed at that step, , it is preferable to receive the user's authorization operation of the erroneously detected authorized point again.

Also, as another modification, it is preferable to always execute the process associated with event detection even at a false detection certified point when at least the highest threshold condition is satisfied. For example, assuming that there are thresholds up to level 5, when the threshold of level 5 is exceeded, even if it is an erroneously detected certified point, the process associated with event detection is always executed. As a result, it is possible to prevent a situation in which the process associated with event detection is not executed even though the condition with the highest threshold is satisfied, and as a result the processed video data is not stored.

If multiple thresholds are set, even if an impact that exceeds the highest threshold occurs, if it is a false detection certified point, it is also possible not to execute the processing associated with event detection. Conceivable. However, if this is done, even if a significantly large impact occurs, the process associated with event detection will not be executed. It is considered that the occurrence of such a remarkably large impact is caused by an accident or the like. Therefore, it is preferable to perform the processing associated with event detection. Therefore, as described above, when at least the condition with the highest threshold is satisfied, it is preferable to always execute the process associated with the event detection even at the erroneously detected certified point.

As another modification, it is conceivable that the size of the erroneously detected certified point is defined by a certain distance range. For example, when an event is detected at a certain point, it is conceivable to define a radius of several meters centering on that point as an erroneously detected authorized point. By doing so, even if the point where the impact occurs is slightly shifted due to the passing speed even if the step is the same, the shifted point can also be treated as an erroneously detected authorized point.

It is also conceivable to define the erroneously detected recognized point by the passing direction when passing the erroneously detected recognized point in addition to the distance range representing the erroneously detected recognized point.

By doing this, when the user enters the distance range of the erroneously detected certified point from a certain direction, it can be determined that the vehicle is in the defined erroneously detected certified point. On the other hand, if it enters the distance range of the erroneously detected certified point from another direction, it can be determined that it is not in the defined erroneously detected certified point.

For example, when entering the distance range of the erroneous detection recognition point from a certain direction, the same level of impact occurs every time, but when entering the distance range of the erroneous detection recognition point from another direction may be defined by the passing direction when passing the erroneously detected recognized point in addition to the distance range representing the erroneously detected recognized point as described above, at the point where no impact occurs each time.

For example, it is assumed that one lane of a two-lane road (assumed to be an up lane) has a step, and the other lane (assumed to be a down lane) does not have a step. In this case, when the vehicle intrudes from the up lane into the distance range of the erroneously detected certified point, a certain amount of impact is generated each time due to the step. Therefore, in this case, it is preferable not to execute the process associated with the event detection as having passed through the erroneously detected certified point. On the other hand, when the vehicle enters the distance range of the erroneously detected recognition point from the down lane, there is no step, so normally no impact occurs. If an impact occurs, it is considered that it is caused by an accident or the like. Therefore, in this case, it is preferable to execute the processing associated with the event detection assuming that the misdetection certified point has not been passed.

Therefore, in consideration of the case where it is necessary to change whether or not to be stored depending on such a passing direction, in addition to the distance range representing the erroneously detected certified point as described above, It may be defined by the passing direction when

As another modified example, it is preferable to perform processing to prevent the number of erroneously detected certified points from increasing too much. For example, when a predetermined period of time has passed after being recognized as a false positive recognition site, or when the number of false positive recognition sites reaches a predetermined number, or in both cases, the false positive recognition recognition site is recognized. It is conceivable not to treat some or all of the points where there are false detections as falsely detected points.

In this way, it is preferable to adopt a configuration in which, when a predetermined period of time has passed since a spot was recognized as a falsely detected certified spot, it is not treated as a falsely detected certified spot. By doing so, the number of erroneously detected certified points can always be suppressed to a predetermined number or less. In addition, this can prevent the number of erroneously detected certified points from becoming enormous. If the number of erroneously detected certified points becomes enormous, when outputting the information specifying the positions of the erroneously detected certified points, a large amount of erroneously detected certified points will be output. It is preferable to prevent the number of points from becoming enormous.

In particular, when the integrated device 1000 is used continuously for a long period of time, the number of erroneously detected certified points increases as the usage period becomes longer. should be suppressed.

Moreover, as another modified example, if no impact occurs even though the vehicle has passed through the erroneously detected certified point, it is conceivable not to treat that point as the erroneously detected certified point thereafter.

As a result, it is possible to avoid treating a point that should no longer be an erroneously detected authorized point as an erroneously detected authorized point.

For example, since there is a step at a certain point, it is assumed that an impact that exceeds some threshold level occurs every time the vehicle passes through. In this case, as described above, this certain point is regarded as an erroneously detected point. However, if the situation changes, for example, if there is no level difference due to pavement work, even if this certain point is passed, no impact that exceeds any level threshold will occur. In such a case, it is better not to treat this certain point as a misdetected certified point. This is because, although it was designated as a false positive recognition point because it is a point where shocks exceeding one of the thresholds occur every time it passes, due to changes in the situation, even if it passes, the shocks exceeding one of the thresholds will not occur. This is because it will not occur.

Furthermore, as another modified example, it is conceivable to determine whether or not the integrated device 1000 instead of the user is the erroneously detected certified point. However, as described above, erroneously setting a falsely detected recognized point when it should not be recognized as a falsely detected recognized point should be avoided for safety reasons. Therefore, the description has been given assuming that the user, not the integrated device 1000, recognizes the falsely detected certified points. However, if the integrated device 1000 can recognize an erroneously detected certified point with an accuracy equal to or higher than that determined by the user, the integrated device 1000 may recognize the erroneously detected certified point.

As described above, for example, the following three examples are conceivable as a method for the integrated device 1000 to recognize an erroneously detected recognized point.

The first example is an example in which the acceleration of each axis of the acceleration sensor 170 is taken into account instead of simply using the acceleration value measured by the acceleration sensor 170 . Assume that the acceleration sensor 170 is capable of measuring three-axis acceleration of the X, Y, and Z axes. In this case, if a large impact is detected only on, for example, the Z-axis (for example, the axis corresponding to the vertical direction) among the three axes, it is determined that there is a step at that point, and that point is misidentified. Authorize as a detection authorization point.

Next, the second example is an example in which if the same degree of impact is detected each time the vehicle passes a certain point, it is determined that there is a step or the like there and that an accident has not occurred. . It is generally unthinkable that an accident or the like will occur each time a certain point is passed. Therefore, if the same degree of impact is detected every time the vehicle passes through a certain point, it is determined that there is a step at that point, and that point is authorized as an erroneously detected authorized point.

Finally, the third example is an example of pattern matching. First, patterns of changes in acceleration of each axis of the acceleration sensor 170 when actually passing through a step are prepared in advance as test data. Pattern matching is then performed between the pattern of changes in the acceleration of each axis measured when passing through a certain point and the prepared pattern. If the pattern of this change is similar, it is determined that there is a step at that point, and that point is authorized as an erroneously detected authorized point.
<Display method>
Next, a display method according to this embodiment will be described. In this embodiment, the positions where event recording was performed due to the occurrence of an event and the positions where manual recording was performed according to the user's operation are displayed, for example, as icons on the map for operation guidance displayed by the car navigation system function. . Note that these icons are called "event icons" in the following description.

When the user presses the event icon on the touch panel 110, the corresponding image data is reproduced. Here, the corresponding image data is imaged by the function of the drive recorder. In other words, in this embodiment, the car navigation function and the drive recorder function are linked.

The event icon may have a single color, but may have different colors depending on the level of the event, for example. By doing so, the user who refers to the event icon can not only know the location of the event, but also know "what level" the event occurred.

Furthermore, it is preferable to be able to distinguish between a position where event recording was performed due to the occurrence of an event and a position where manual recording was performed according to user's operation. Therefore, the color of the event icon representing the position at which manual recording was performed is set to a different color from the color of the event icon representing the position at which event recording was performed. In addition, it is preferable to assign colors according to, for example, signal signs so that the user can intuitively recognize them.

For example, the event icon for a level 1 event, which is an event based on minor impacts, is green. The event icon for a level 1 event, which is an event based on an intermediate level impact, is yellow. Furthermore, the event icon for level 5 events, which are events based on large impacts, is red. Also, the event icon corresponding to manual recording is colored indigo.

[Table 1] below shows an example of this color assignment. The following description is based on this allocation.

Then, the event icons to which the colors are assigned in this way are displayed on the touch panel 110 so as to be superimposed on the map for operation guidance as shown in FIG.

Furthermore, as described above with reference to FIG. 2, in this embodiment, the upper limit of the number of records that can be recorded is determined for each of manual recording and event recording. For example, the maximum number of video files for manual recording and event recording is 20 in total, that is, 10 in total. Then, when a new recording is performed, even if the user has not yet viewed the video, the video is deleted because it is the oldest. Therefore, it is preferable to let the user know which ones are old and will soon be deleted. Then, it is preferable to encourage viewing before deletion.

In addition, the user can grasp which event icon corresponds to the event recording that just happened, which event icon corresponds to the manual recording that was performed three times ago, for example, and the like. It is preferable to keep

Therefore, instead of simply displaying each event icon in a different color, for example, the event icon is represented by circled numbers including chronological numbers. This allows the user to grasp which event icon is new, which is old, and how old it is.

The first control unit 100 uses map information stored in the main storage unit 190 to display these event icons. In addition, the information received from the second control unit 200 and stored in the main storage unit 190 when the manual recording has occurred, “the fact that the manual recording has occurred, the date and time when the manual recording was performed, and the time when the manual recording was performed”. A set of location information that specifies the location where the Furthermore, the information stored in the main storage unit 190 when an event occurs is "location information for specifying the location where the event occurred, the level of the event that occurred, and the date and time of the event that occurred. Use "things".

FIG. 6 shows a specific example of displaying event icons with these contents.

Referring to FIG. 6, first, a map for operation guidance is displayed on touch panel 110 . It can be seen that i8 on the map is an event icon that is colored indigo and represents the position where manual recording was performed. Also, since the number is 1, it can be seen that it represents the position where manual recording was most recently performed.

Also, i9 on the map is a yellow event icon representing a position where level 3 event recording was performed. In addition, since the number is 2, it can also be understood that it represents the position of the event recording performed one before the manual event performed at i8 on the map.

Furthermore, it can be seen that i10 on the map is an event icon that is red and represents the location where the level 5 event recording was performed. In addition, since the number is 3, it can also be understood that it represents the position of the event recording performed one before the event recording corresponding to i9 on the map.

Furthermore, it can be seen that i11 on the map is an event icon that is green and represents the position where the level 1 event recording was performed. In addition, since the number is 4, it can also be understood that it represents the position of the event recording performed one before the event recording corresponding to i10 on the map.

Furthermore, i12 on the map is an event icon representing the current position and traveling direction of the vehicle in which the integrated device 1000 is installed.

A user who referred to the information displayed in FIG. 6 may say, for example, "We are approaching a place where a level 5 event occurred before, so let's not drive in such a way that the event will occur this time." and the like, and judgment such as "Do not pass through the place where the manual recording was performed before if you continue at this rate." That is, it is possible to present useful information to the user.

Also, when the user presses an event icon, the video file corresponding to the event icon is played.

Specifically, when any event icon is pressed, a list of event icons including that event icon is displayed on the right half of the touch panel 110, for example, as indicated by i13 in FIG. For this reason, the map is displayed, for example, in the left half, as indicated by i14 in FIG.

Based on where on the touch panel 110 is pressed, the first control unit 100 determines which event icon in the event list the user has pressed. Then, the date and time when the event corresponding to the pressed event icon was recorded or the date and time when the manual recording corresponding to the pressed event icon was performed are read from the main storage unit 190 . Then, it transmits the read date and time to the second control unit 200 .

The second control unit 200 searches the second storage unit 230 using the received date and time as a search key. Then, the video file corresponding to the date and time is read. Here, since two video files form a set for each manual recording and each event recording, the two video files forming this set are read. Then, the second control unit 200 decodes these two read video files to obtain image data. Then, the image data is transmitted to the first control unit 100 .

The first control unit 100 reproduces by outputting the received image data to the touch panel 110 . By referring to the reproduced image data, the user can confirm how manual recording and event recording were performed.

Next, the history icon, which is an icon separate from the event icon, will be described. As described above, there is an upper limit to the number of video files that can be protected for manual recording and event recording. Therefore, when the number exceeds 10, for example, the oldest video files are deleted in order. Therefore, the event icon corresponding to the deleted video file is also deleted.

Here, the reason why the video file is deleted is that the capacity of the second storage unit 230 is taken into consideration. is preferred.

In this regard, the data size of the information on the occurrence position of manual recording and event recording stored in the main storage unit 190 is smaller than the data size of the video file.

Therefore, these pieces of information are kept stored in the main storage unit 190 without being deleted. Then, using this information, the locations of occurrence of manual recording and event recording and icons representing the levels of event recording are displayed on the map. In the following description, such icons are called "history icons" to distinguish them from event icons.

Note that the amount of data required to display history icons is small as described above. On the other hand, if history icons are displayed for too many past manual recordings and event recordings, an extremely large number of icons will be displayed on the screen, which will interfere with operation guidance.

Therefore, an upper limit is set for the number of icons to be displayed. For example, assume that there are 10 event icons and 490 history icons, 500 in total.

Also, a distinction should be made between history icons and event icons. For this purpose, for example, the display modes, such as the shape of the history icon and the shape and size of the event icon, are made different. For example, different shapes such as a round shape and a rectangular shape are used. Alternatively, they both have the same round shape, but the sizes are different such that the event icon is larger and the history icon is smaller. Also, in any case, the shape and size of each history icon should be such that the color can be discriminated. In the following description, it is assumed that the history icons are displayed in diamonds.

The information used to display the history icon is specifically the information received from the second control unit 200 and stored in the main storage unit 190 when manual recording occurs. A set of the occurrence of a manual recording, the date and time when the manual recording was performed, and the location information specifying the location where the manual recording was performed. Furthermore, the information stored in the main storage unit 190 when an event occurs is "location information for specifying the location where the event occurred, the level of the event that occurred, and the date and time of the event that occurred. Use "things".

FIG. 8 shows a specific example of displaying event icons with these contents. In the specific example of FIG. 8, the video file corresponding to the event icon shown in the specific example of FIG. 6 is deleted and replaced with a history icon because it has become old.

Referring to FIG. 8, first, a map for operation guidance is displayed on touch panel 110 . i15 on the map is a history icon that is colored indigo and represents a position where manual recording was performed.

Also, i16 on the map is a history icon that is colored yellow and represents a position where level 3 event recording was performed.

Furthermore, i17 on the map is a history icon that is red and represents a position where level 5 event recording was performed.

Furthermore, i18 on the map is a history icon that is green and represents a position where level 1 event recording was performed.

Further, i19 on the map is an icon representing the current position and traveling direction of the vehicle in which the integrated device 1000 is installed.

By displaying not only the event icon but also the history icon in this manner, the user can grasp the location where the event frequently occurs.

Also, normally, the above-described event icon and history icon are displayed on the map for operation guidance. You may make it display the icon showing a position on the map for operation guidance. The icon representing the position of the erroneous detection certified point is called a ``false detection certification icon''.

By displaying the erroneous detection recognition icon on the map in this way, for example, it is possible to know in advance that a predetermined impact will occur because the vehicle will pass the erroneous detection recognition point. In addition, it is possible to understand the reason why the video data, which is the process associated with the occurrence of the event, is not stored despite the occurrence of the impact.

The erroneous detection recognition icon may be in a single color, but it is preferable to use a different color depending on, for example, the level of the threshold that triggered the recognition of the erroneous detection recognition point. For example, if a point where an event occurs beyond a level 1 impact is recognized as an erroneously detected location, and if a point where an event occurs beyond a level 2 impact becomes an erroneous detection recognized location, The certification icons may be of different colors. By doing this, the user who refers to the false positive recognition icon can not only know the position of the false positive recognition point, but also know "how many levels" the threshold has been exceeded before becoming the false positive recognition point. Because I know everything.

In addition, in order to distinguish between the false detection recognition icon and the event icon and history icon, the false detection recognition icon and the event icon and history icon should be displayed differently in terms of icon shape and color.

In addition, in the case where the occurrence of an impact exceeding the threshold value is satisfied continuously at a plurality of points at intervals of less than a predetermined time interval, and if the plurality of points are all certified points, the plurality of points are set as one group, and instead of displaying a large number of icons for specifying the positions of each of the plurality of certified spots, an icon having a shape for specifying the position of this one group may be displayed.

By doing so, it is possible to prevent the screen from becoming difficult to see due to the display of a large number of icons specifying the respective positions of the plurality of points. In addition, icons for specifying the positions of each of the plurality of points are not displayed, but icons for specifying the positions of one group are displayed, so that the user can grasp that there are a plurality of erroneously detected certified points at that position. It is good because it can be done.

There are roads that are continuously provided with steps for the purpose of suppressing the traveling speed and alerting the driver of the moving object by giving sound and vibration to the driver. When passing through such a road, impacts that continuously exceed the threshold occur. However, if information for specifying each point is output for each point where an impact exceeding the threshold has occurred, the amount of information to be output increases. Therefore, by treating each of these points as one group and outputting an icon specifying the position of one of these groups, it is possible to prevent the number of output icons from becoming unnecessarily large. In this case, it would be troublesome for the user if each of these points were to be recognized as the erroneously detected recognized point. Therefore, it is preferable that each of the points included in one group can be collectively identified as the erroneously detected identified point by a single operation.
<Screen transition>
Next, how the screen transitions according to the state of the vehicle and the user's operation will be described with reference to the transition diagrams of FIGS. 9 to 11. FIG.

First, refer to FIG. When the first control unit 100 is activated, a main menu is displayed like the screen S1. On the main menu screen, various functions such as navigation, TV, music, picture, and drive recorder can be selected. Among them, the functions of the navigation and the drive recorder, which are features of the present embodiment, will be described.

When the [navigation] button is selected on the screen S1, the navigation function is activated and the screen transitions to the screen S2.

On the screen S2, as described with reference to FIGS. 6 and 8, event icons and history icons are displayed on a map for operation guidance, and operation guidance is executed with voice output. The content of such display is the content described in the section <Display Method> above. Also, the method of determining the occurrence of an event by the first control unit 100, the operation when the event occurs, and the like are the contents described in the section <Occurrence of event> above. Assume that the user presses the [Shortcut] button. Here, it is assumed that the "shortcut" button is associated with "camera image". In this case, the screen transitions to the screen S3, and the real-time image, which is the image currently captured by the camera 210, is displayed on the screen. In this state, when the user presses the [End] button, the screen transitions to S2, and operation guidance is executed again.

Further, when any [icon] button is pressed in the state of the screen S2, the process for reproducing the video file corresponding to the pressed event icon or history icon is started. Specifically, the screen is changed to S4, a message indicating that the continuous recording will be temporarily interrupted is output, and the user's selection of either the [Yes] or [No] button is accepted.

Here, the reason for suspending the constant recording is to prevent the overwriting of the image data being reproduced when it is determined that a new event has occurred during the image data reproduction. This is because it becomes possible.

Also, in a case where each image data is assigned a number and managed as a list, and when it is determined that a new event has occurred during image data reproduction, the number assigned to the new image data is It is also possible to prevent a situation in which numbers assigned to image data being reproduced are duplicated. For example, when recording data currently being played back is managed as the latest image data, if new image data is generated, it is managed which data is the latest data after the playback ends. This is because it is possible to prevent a situation in which it becomes impossible.

Here, if the user presses the "No" button, the screen transitions to S2, and operation guidance is continued.

On the other hand, if the user presses the "Yes" button, the screen transitions to screen S5, and the event list is displayed on the right half of the screen as described with reference to FIG. Here, the user does not want to reproduce the video file corresponding to the icon selected from the event list on the screen S5, but wants to reproduce the video file corresponding to the icon selected on the screen S2.

Therefore, the entire event list is treated as an [event item] button, and when the [event item] button is pressed for the first time, the map is moved to the coordinate values of the icon selected on the screen S2. Then, when the [event item] button is pressed for the second time, the screen transitions to the screen S6 and the moving image reproduction is started.

On the screen S6, a message "Video will be reproduced" is displayed while processing for generating a moving image is being performed. When the message "Video will be reproduced" is displayed for a length longer than a predetermined time required for processing for generating a moving image, it is determined that a time-out has occurred, and the screen transitions to S7. Then, on the screen S7, the video file corresponding to the icon selected on the screen S2 is reproduced.

When the user presses the [Return] button during or after shooting, the screen transitions to the screen S5. Then, when the user presses the [Back] button on the screen S5, the screen transitions to the screen S2, and operation guidance is continued. In addition, constant recording is resumed without requiring user's operation.

Next, as described above, when any [icon] button is pressed in the state of the screen S2, instead of playing back the video file corresponding to the pressed icon, the user selects the icon from the event list. The operation of selecting and reproducing the video file corresponding to the icon selected from the event list will be described.

When the [MENU] button provided at the bottom of the screen is pressed in the state of the screen S2, the screen transitions to the screen S8, which is the menu screen of the navigation function.

After that, when the press of the [Register/Edit] button is accepted in the state of the screen S8, the screen transitions to the screen S9, which is a menu screen for registration/editing.

Then, when the [event] button is pressed in the state of the screen S9, the screen changes to the screen S10 of FIG.

In the screen S10, similarly to the screen S4, a message indicating that the continuous recording will be temporarily interrupted is output, and the user selects either [Yes] or [No] button. The reason why the continuous recording is temporarily interrupted is as described in the description of the screen S4.

Here, if the user presses the [No] button, the screen transitions to screen S9 in FIG. 9, which is a menu screen for registration/editing.

On the other hand, if the user presses the "Yes" button, the screen transitions to S11, and the event list is displayed on the right half of the screen as described with reference to FIG. Unlike the screen S5, the user has not selected an icon on the screen S2, so the user's icon selection from the event list on the screen S5 is accepted.

Then, playback of the video file corresponding to the icon selected by the user is started. The subsequent processing on the screens S6 and S7 is the same as the processing when the screen S5 transitions to the screen S6, so detailed description thereof will be omitted. In FIG. 10, when the return button is pressed on the screen S7, the screen returns to the screen S5, but it is also possible to return to the screen S11 instead of the screen S7.

The screen transitions when using the car navigation function have been described above. Next, screen transition when using the drive recorder function will be described.

First, when the [drive recorder] button is pressed on the screen S1, the screen transitions to the screen S12 or screen S13 shown in FIG. Here, regarding the condition for transitioning to which screen, the all-in-one device 1000 is not installed in the automobile and the all-in-one device 1000 is receiving power from the secondary battery included in the power supply unit 310. to the screen S12. On the other hand, if the integrated device 1000 is installed in the vehicle and the integrated device 1000 is receiving power from the vehicle, the screen transitions to S13.

First, the former case where the all-in-one device 1000 is not installed in the automobile and the all-in-one device 1000 is receiving power from the secondary battery included in the power supply unit 310 will be described. In this case, since the battery capacity of the secondary battery has an upper limit, power consumption must be suppressed. Also, in this case, the user carries and uses the integrated device 1000, and since the camera 210 is not fixed, it is difficult to effectively utilize the function of the drive recorder. Therefore, in this embodiment, the function of the drive recorder is not operated when power is supplied from the secondary battery. Then, in order to inform the user of this fact, when the screen is shifted to the screen S12, a message such as "The recording/reproducing function of the drive recorder does not operate while the machine is being driven by the built-in battery" is displayed. Then, after a predetermined period of time has elapsed during which it is considered that the user can recognize this message, it is determined that a time-out has occurred, and the screen transitions to screen S1.

Next, a case will be described in which the integrated device 1000 is installed in an automobile and the integrated device 1000 receives power from the automobile, so that the screen transitions to S13.

On the screen S13, the real-time video imaged by the camera 210 is reproduced in full screen display. In this state, when the touch panel 110 is pressed by the user, that is, when any part of the screen is touched, the screen transitions to the screen S14.

Then, the screen S14 displays an [Exit Application] button. When the user presses the [Exit application] button, the operation of the application that implements the drive recorder function is terminated, and the screen transitions to screen S1. On the other hand, when the pressing of the screen is accepted in the screen S14, the screen returns to the screen S13 again, and the real-time video is reproduced in full screen display. It should be noted that, on the screen S14, for example, a button for changing settings may be displayed, and when the button for changing settings is pressed, the screen may further transition to a screen for performing various settings related to the drive recorder function, for example. .

Further, when the user's operation is received while the screen S13 and the screen S14 are being displayed, the manual recording described with reference to the middle part of FIG. 2 is started with this as a trigger. That is, the real-time video reproduced on the screen S13 and the screen S14 is used as a preview image for manual recording.

Next, with reference to FIG. 12, how the screen transitions according to the user's operation when certifying and canceling the erroneously detected certifying point will be described.

Here, the screen transition in the case of certifying an erroneously detected certified point is basically as described with reference to the transition diagrams of FIGS. 9 to 11, so refer to the transition diagrams of FIGS. 9 to 11 The description of the content that overlaps with the content described above will be omitted, and only the content that is different will be described.

On the screen S2, it is assumed that the "shortcut" button is associated with "display false detection certification icon". When the [Shortcut] button is pressed, the screen S2 remains unchanged without transitioning to the screen S3, but instead of the event icon and the history icon, the false detection recognition icon is displayed on the map. This allows the user to refer to the false positive identification icon. If the [Shortcut] button is pressed again in this state, the screen S2 remains, but the event icon and history icon are displayed on the map instead of the false detection recognition icon.

If any [icon] button is pressed while the false detection authorization icon is displayed on the map on the screen S2, the screen Transition to S21. Then, on the screen S21, the user presses either [Yes] or [No] button to confirm whether or not the point identified by the pressed erroneous detection authorization icon can be left as the erroneous detection authorization point. accept the choice of

Here, when the "Yes" button is pressed, the point identified by the pressed false detection recognition icon remains the false detection recognition point, and the screen returns to screen S2.

On the other hand, if the [No] button is pressed, the point specified by the pressed false detection recognition icon is not the false detection recognition point. Specifically, the date and time when the event occurred at the misdetection certified point and the position of the misdetection certification point corresponding to the point specified by the pressed false detection certification icon stored in the main storage unit 190 are displayed. Delete the set of information in which the specified position information is linked and the identifier for specifying this erroneously detected certified point. Then, the screen returns to the screen S2.

If any [icon] button is pressed while event icons and history icons are displayed on the map on screen S2, screens S4 and S21 are displayed as shown in the lower part of FIG. Instead, it transitions to the screen S22. Then, on the screen S22, the user presses either a [Yes] or [No] button to confirm whether or not the point specified by the pressed false detection recognition icon is to be newly set as a false detection recognition point. accept the choice of

Here, when the "Yes" button is pressed, it is assumed that the point specified by the pressed event icon or the pressed history icon is recognized as an erroneously detected recognized point. Then, in the main storage unit 190, the date and time when the event occurred at the erroneously detected certified point corresponding to the point specified by the pressed event icon or the pressed history icon, and the location for specifying the position of the erroneously detected certified point A set of information in which information is linked and an identifier for specifying this falsely detected certified point are stored. Then, the screen returns to the screen S2.

On the other hand, if the [No] button is pressed, the screen transitions to the screen S4 without performing the processing for recognizing the erroneously detected recognized spot.

By doing so, it is possible to certify and cancel the erroneously detected certifying point.
<Battery control>
Next, control of the battery in this embodiment will be described.

The power supply unit 310 of the integrated device 1000 of this embodiment receives power supply from an external device via the USB terminal 320 as described with reference to FIG. Here, the external device is, for example, an automobile in which the integrated device 1000 is installed.

Specifically, one end of the cigar plug cord is inserted into the cigar lighter socket of the automobile. Then, the other end of the cigar plug cord is connected to the USB terminal 320 . Also, use a cigar plug cord with a converter. Assume that the cigar plug cord and converter have a rated voltage of 5V and a rated current of 2A, for example.

After that, when the automobile engine starts, power supply from the cigarette lighter socket is started in conjunction with this. Then, when the automobile engine stops, the power supply from the cigarette lighter socket also stops.

Next, with reference to FIG. 13, the detailed configuration of power supply section 310 will be described. Referring to FIG. 13, the power supply unit 310 includes a power control unit 311, a lithium ion battery 312, and a supercapacitor 313 (registered trademark). Also, the power supply unit 310 is connected to the first control unit 100 and the second control unit 200 . Of the functional blocks shown in FIG. 1, functional blocks that are not directly related to the description of battery control are omitted in FIG.

Note that the supercapacitor 313 corresponds to the "capacitor" of the present invention. Also, the lithium ion battery 312 corresponds to the "secondary battery" of the present invention. Furthermore, the power source fed from the cigarette lighter socket of the automobile corresponds to the "external power source" of the present invention.

Here, the power control unit 311 has a function of controlling to which device a voltage is applied. The power control unit 311 is implemented by, for example, a power management IC. Also, the first control unit 100 may perform part or all of the control of the power supply control unit 311 . In FIG. 13, signal lines for transmitting and receiving signals for the first control unit 100 to control the power supply control unit 311 are indicated by dashed lines. On the other hand, lines for applying voltage are shown in FIG. 13 as solid lines.

The lithium ion battery 312 is a secondary battery that can be used as a battery after storing electricity by charging. The lithium ion battery 312 is charged under the control of the power control unit 311 . Then, when the integrated device 1000 receives power supply from an external device, the first control unit 100 is driven by the power supplied from the external device.

On the other hand, the first control unit 100 is driven by power supplied from the lithium ion battery 312 when the integrated device 1000 is not powered by an external device. Also, as described above in the <screen transition> section, when the integrated device 1000 is not receiving power supply from an external device and is driven by power supplied by the lithium ion battery 312, the drive recorder stop functioning. Since the purpose of this is to reduce power consumption, the application of the voltage to the second control unit 200 itself is stopped in addition to simply shutting down the software operating in the second control unit 200. do.

The supercapacitor 313 is an electric storage device, and is charged while the integrated device 1000 is receiving power from an external device.

In this regard, in this embodiment, when the integrated device 1000 is removed from the automobile, the second control unit 200 stores the information cached by itself in the second storage unit 230, which is a non-volatile memory. to prevent data corruption by performing shutdown processing.

However, when the integrated device 1000 is removed from the automobile as described above, application of voltage to the second control unit 200 is stopped. Therefore, the second control unit 200 uses the charge stored in the supercapacitor 313 to perform this shutdown process. Therefore, the supercapacitor 313 uses a capacitor with a capacity that can guarantee that the shutdown processing is performed in this way.

The information cached by the second control unit 200 is, for example, real-time video that has been cached and has not yet been converted into a video file.

The first control unit 100 also controls the power supply. For example, the first control unit 100 includes, among the units shown in FIG. It controls the power supply of the unit 180 and the main storage unit 190 . Also, part or all of the control of the power control unit 311 may be performed by the first control unit 100 .

On the other hand, the second control unit 200 controls the power of the camera 210, the microphone 220, and the second storage unit 230 among the units shown in FIG.

Next, the basic concept of battery control in this embodiment will be described. In this embodiment, the activation of the first control unit 100 and the second control unit 200 and the charging of the supercapacitor 313 and the lithium ion battery 312 are not all performed in parallel, but by controlling the timing of performing, Do it step by step. This is to activate the first control section 100 and the second control section 200 and charge the supercapacitor 313 and the lithium ion battery 312 without exceeding the rated current of the cigar plug cord.

Here, the rated current of the cigar plug cord is 2A, for example. In this regard, it is conceivable to use a cigar plug cord with a rated current exceeding 2A. However, as the rated current increases, it becomes necessary to thicken the cigar plug cord. This is because conductors such as electric wires that form cords also have resistance, though small, and the heat generated by the conductors may melt the insulating coating.

However, if the cord is thickened, it becomes difficult to handle the cord, which is very inconvenient for the user who uses the integrated device 1000 in a limited space such as a car. Another problem is that the use of thick cords increases manufacturing costs.

Therefore, in the present embodiment, as described above, the activation of the first control unit 100 and the second control unit 200 and the charging of the supercapacitor 313 and the lithium ion battery 312 are not all performed in parallel. It is performed step by step by controlling the timing. As a result, in this embodiment, the maximum value of the current when the integrated device 1000 is activated is suppressed.

Next, the power control processing of this embodiment will be described in detail with reference to the flowcharts of FIGS. 14 and 15. FIG.

First, with the integrated device 1000 in the shutdown state and connected to the car charger, the car engine is started. Along with this, the supply of power to the integrated device 1000 is started (Yes in step A11).

Then, the power control unit 311 starts applying voltage to the first control unit 100 . As a result, the first control unit 100 starts activation processing (step A12). Such activation processing includes, for example, processing for activating the touch panel 110 and the GPS sensor 160 .

The first control unit 100 that has performed the activation process displays on the touch panel 110 . A screen S1 shown in FIG. 9 is displayed at this time. Then, when the [navigation] button 140 is pressed, the navigation function is executed (step A13). Also, even if the [drive recorder] button 140 is pressed, the drive recorder function is not yet executed. Therefore, a message such as "The drive recorder is being activated. Please wait for a while." is displayed on the screen, as in the screen S14 shown in FIG. Then, after a predetermined period of time has elapsed during which it is considered that the user can recognize this message, it is determined that a time-out has occurred, and the screen transitions to screen S1. In this way, first, by activating the first control unit 100 and displaying on the touch panel 110, it is possible to notify the user that the activation process is being performed.

Also, the power control unit 311 starts applying voltage to the supercapacitor 313 . Along with this, the supercapacitor 313 starts storing electricity, and the voltage of the supercapacitor 313 rises (step A14).

Next, it is determined whether or not the current voltage of the supercapacitor 313 is higher than a predetermined first voltage (step A15). Then, when the current voltage of supercapacitor 313 becomes higher than the predetermined first voltage (Yes in step A15), power supply control section 311 starts applying voltage to second control section 200. FIG. As a result, the second control unit 200 starts activation processing. This start-up processing also includes processing for starting up the camera 210 and the microphone 220 .

However, if the drive recorder function is executed, the maximum current may exceed the rated current of the cigar plug cord. Therefore, the second control unit 200 performs activation processing, but does not yet execute the function of the drive recorder. Therefore, even if the [Drive Recorder] button 140 is pressed at this time, a message such as the screen S14 shown in FIG. 16 is displayed as in step A13, and the drive recorder function is not executed.

Next, it is determined whether or not the current voltage of the supercapacitor 313 is higher than a predetermined second voltage (step A17). Here, the predetermined second voltage is a value higher than the predetermined first voltage.

Then, when the current voltage of supercapacitor 313 becomes higher than the predetermined second voltage (Yes in step A17), it means that supercapacitor 313 is sufficiently charged, and a large amount of current is accumulated in supercapacitor 313. is no longer necessary. Therefore, when step A17 becomes Yes, the process proceeds to step A18, and the second control unit 200 executes the drive recorder function (step A18). Further, the power control unit 311 starts applying voltage to the lithium ion battery 312 . Thereby, charging of the lithium ion battery 312 is started (step A19).

As described above, in this embodiment, the timing of applying voltage to each unit included in the integrated device 1000 is controlled. As a result, it is possible to suppress the maximum value of current when the integrated device 1000 is activated, and it is possible to eliminate the need to make the cigar plug cord thicker than necessary.

This point will be described using specific values. For example, assume that 1.3 A, for example, is used as the voltage is applied to the first control unit 100 in step A12. Also, with the application of the voltage to the supercapacitor 313 in step A14, for example, 0.5 A is used at least until Yes in step A15. Furthermore, it is assumed that 0.2 to 0.3 A, for example, is used with the application of voltage to the second control unit 200 in step A16. Furthermore, it is assumed that, for example, 0.35 A is used as the voltage is applied to the lithium ion battery 312 in step A19.

When these currents are added up, a total of 2.35 to 2.36 A is required, which exceeds the 2 A rated current of the cigar plug cord described above. However, in this embodiment, the integrated device 1000 can be activated without exceeding the rated current of 2 A by controlling the timing of applying voltage to each part included in the integrated device 1000 .

Next, battery control after the integrated device 1000 is started will be described with reference to FIG.

The integrated device 1000 executing the navigation function and the drive recorder function continues to monitor whether or not the power supply from the car charger is interrupted as the engine of the car stops. Further, it continues to monitor whether or not integrated device 1000 has been removed from the car charger by disconnecting the cigar plug cord from USB terminal 320 or by disconnecting the cigar plug cord from the car charger (step A20). No and No in step A22).

Then, when the power supply from the car charger is interrupted due to the stop of the automobile engine (Yes in step A20), shutdown processing of the first control unit 100 and the second control unit 200 is performed. At this time, the shutdown processing of the first control unit 100 is performed by power supply from the lithium ion battery 312 , and the shutdown processing of the second control unit 200 is performed by power supply from the supercapacitor 313 . Then, the process returns to step A2 and waits until the power is supplied again.

On the other hand, when integrated device 1000 is removed from the car charger by removing the cigar plug cord from USB terminal 320 or by removing the cigar plug cord from the car charger (Yes in step A22), the second The controller 200 starts shutdown processing by power supply from the supercapacitor 313 . By doing so, the user cannot use the drive recorder function, but since the first control unit 100 does not particularly shut down, the user can continue to use the navigation function. In other words, the integrated device 1000 can be used as a portable navigation system. Note that the first control unit 100 continues to operate by power supply from the lithium ion battery 312 . Since only one of the two controllers can be shut down in this manner, the other controller does not need to be shut down and restarted, and can continue to operate.

Next, it is determined whether or not it is connected to the car charger of the automobile again and whether or not it is connected to an external device other than the automobile. Here, the external device is, for example, a personal computer connected to the USB terminal 320 via a USB cable. Whether the connected device is a car charger of a car or a personal computer may be determined by a signal output from a USB cable, for example. For example, a USB connector has five lines (VBus/D−/D+/ID/GND). If the ID line is short-circuited to the GND line, it can be determined that it is connected to the personal computer. On the other hand, if the ID line is open (unconnected), it can be determined that it is connected to the car charger.

If it is connected to an automobile (Yes in step A24: automobile), the process returns to step A2 and waits until power is supplied again.

On the other hand, if it is connected to an external device (Yes in step A24: external device), the process proceeds to step A25 to shut down the first control unit 100. FIG. This is because when the integrated device 1000 is connected to a personal computer, it is considered unnecessary to execute the navigation function any more. In addition, the output from the USB terminal 320 of the personal computer may not be able to supply enough current to drive the integrated device 1000 .

After shutting down the first control unit 100, charging of the lithium ion battery 312 is started in preparation for using the integrated device 1000 as a portable navigation system again (step A26).

After that, it monitors whether or not it has been removed from the external device (step A27). Then, if it is removed from the external device (Yes in step A27), the first control unit 100 starts startup processing by power supply from the lithium ion battery 312 in order to realize the function of the portable navigation system (step A28).

The first control unit 100 performs display on the touch panel 110 and also performs a navigation function.

As described above with reference to FIG. 15, in this embodiment, when the vehicle engine stops and the power supply from the car charger is interrupted, when the car charger is removed from the car charger, and when it is connected to an external device, It is possible to drive or shut down the first control unit 100 and the second control unit 200 appropriately in each case.
<Car navigation>
Next, the car navigation function of the first control unit 100 will be described in more detail. A predetermined alarm is output when the positions of the target objects such as the above are in a predetermined positional relationship. Therefore, the main storage unit 190 stores information on targets to be detected (target position information including longitude and latitude, target type information, etc.), accident-prone areas, traffic enforcement information, and the like. There is traffic safety information for safe driving, landmarks, and various information useful for driving. Each piece of information is registered by associating specific types of information (types of targets, types of traffic enforcement, accident-prone areas, names of landmarks, etc.) with location information.

The distance to the target at which the warning is issued can be changed for each type of target. As the mode of the warning, there are a voice warning using the speaker 120 and the like using the touch panel 110, as in the above case. In this embodiment, the all-in-one device 1000 implements a car navigation function and thus has map data.

Therefore, as a basic screen, the first control unit 100 has a function of reading road network information around the current position and displaying a map around the current position on the touch panel 110 . Then, the warning screen is displayed on the touch panel 110 so as to overlap the currently displayed screen. When the map is displayed, if the distance between the current position and the LH system, which is a type of speed measuring device that is one of the traffic monitoring points, becomes, for example, 500 m, a warning screen is displayed. Further, the first control unit 100 performs a process of outputting from the speaker 120 a warning voice indicating the type of warning and the distance, such as "It is the LH system 500 m ahead."

Meanwhile, the first control unit 100 for realizing the navigation function also operates as follows. First, the main storage unit 190 stores road network information for navigation.

The first control unit 100 has a function of reading road network information around the current position from the main storage unit 190 and displaying a map around the current position on the touch panel 110 . The first control unit 100 can use this road network information to search for a route from one position to another. The main storage unit 190 also stores a telephone number database in which telephone numbers are associated with location information and names of houses, companies, facilities, etc. of the telephone numbers, and addresses are associated with the location information of the addresses. A stored address database is provided. The main storage unit 190 also stores location information of traffic monitoring points such as speed measuring devices together with their types.

Also, the first control unit 100 has a function of performing processing of a general navigation device. That is, the touch panel 110 displays the map around the current position at any time, and the destination setting button 140 is displayed. When touch panel 110 detects a touch at a position corresponding to the display position of destination setting button 140, first control unit 100 performs a destination setting process. In the destination setting process, a destination setting menu is displayed on touch panel 110 to prompt the user to select a destination setting method. The destination setting menu has a phone number search button 140 and an address search button 140 for prompting the user to select a destination setting method. When it is detected that the phone number search button 140 has been touched, a phone number input screen is displayed, and the position information corresponding to the inputted phone number is obtained from the main storage unit 190 . When it is detected that the address search button 140 has been touched, an address selection input screen is displayed, and the position information corresponding to the input address is acquired from the main storage unit 190 . Then, the acquired position information is set as the position information of the destination, and a recommended route from the current position to the destination is obtained based on the road network information stored in the main storage unit 190 . As a method for calculating this recommended route, a known method such as the Dijkstra method can be used.

Then, the first control unit 100 displays the calculated recommended route together with the surrounding map. For example, as shown in FIG. 17, a route i23 from the current position i21 to the destination i22 is displayed in a predetermined color (eg, red) as the recommended route. This is similar to a general navigation system. In this embodiment, the first control unit 100 compares the position information on the route i23 with the position information of the target such as the traffic monitoring point stored in the main storage unit 190, and determines the position on the route i23. Displays the positions of traffic monitoring points, etc.

As a result, for example, as shown in FIG. 17, a balloon is displayed from a position on the road, and the type of traffic monitoring point at that position stored in the main storage unit 190 is displayed in the balloon. For example, FIG. 17(a) is a display example of a warning point search screen, showing an example of displaying traffic monitoring points i25a to i25f. The traffic monitoring point i25a displays the letter "N" in a balloon to indicate the N system. Traffic monitoring points i25b, i25c, and i25e display the letters "LH" in balloons to indicate the LH system. The traffic monitoring point i25d displays the character "Loop" indicating the loop coil in a balloon. The traffic monitoring point i25f displays the letter "H" in a balloon to indicate the H system. In this way, when the touch panel 1108 detects a touch on the balloon position in the simple display state in which characters are displayed in the balloon, the simple display is switched to the detailed display as shown in FIG. 4B.

Further, as shown in FIG. 4(a), a traffic monitoring point type designation section i26 is displayed on the lower right side of the touch panel 110. FIG. The traffic monitoring point type specifying portion i26 is a portion that displays buttons 140 listing the types of traffic monitoring points existing on the route i23. In the example of FIG. 4A, the type button 140i27a of "N" indicating the N system of the traffic monitoring point i25a, the type button 140i27b of "LH" indicating the LH system of the traffic monitoring points i25b, i25c, and i25e, and the traffic A "loop" type button 140i27c indicating the loop coil of the monitoring point i25d and an "H" type button 140i27d indicating the H system of the traffic monitoring point i25f are displayed. When first control unit 100 detects touch of type button 140 on the display unit from touch panel 1108, first control unit 100 reverse-displays touched type button 140 and displays a traffic monitoring point corresponding to touched type button 140. The display mode of is switched to detailed display if simple display is in progress, and switched to simple display if detailed display is in progress.

The all-in-one device 1000 of this embodiment has a peripheral search function as a method of setting a destination (hereinafter also including a waypoint). When the peripheral search function is selected and activated, the first control unit 100 extracts facilities that meet the specified conditions and are close to the current position, and draws the extraction results on the touch panel 110. do. Then, the user can select one of the candidates drawn on the touch panel 110 and confirm it to designate it as a destination (including a waypoint).

That is, in order to implement such a function, the main storage unit 190 of the present embodiment stores information about each facility in association with position information and information about the classification of the facility. The information about the classification of facilities is a plurality of types of items grouped by the name of the genre that matches each facility.

In this embodiment, when one of the items is specified, the first control unit 100 extracts facilities that match the specified item and are close to the current position, and outputs the extraction result to the destination. is drawn on the touch panel 110 as a candidate for . The user can specify a destination by selecting one of the candidates drawn on touch panel 110 .

When any one of the items is selected, the first control unit 100 accesses the main storage unit 190, the facility existing within a reference distance (for example, 10 km) centering on the current position, Extract items that match the classification of the item. Then, a predetermined number (for example, 10) of the closest facilities are superimposed on the corresponding locations on the map drawn on the touch panel 110, and icons (marks) indicating the facilities are drawn. As facility information stored in the main storage unit 190 , respective icons are associated with each facility and registered.

If the current position exists on the map drawn on the touch panel 110, the vehicle icon indicating the vehicle is superimposed on the position corresponding to the current position. Furthermore, when drawing the icons of such facilities, numbers are attached and displayed in order of proximity from the own vehicle. The number is updated at any time as the vehicle moves.

Then, when the user selects a desired facility, the first control unit 100 recognizing it obtains a recommended route with the facility as the destination, and draws the result superimposed on the map of the touch panel 110 .

Furthermore, the first control unit 100 has a function of performing route guidance to a set destination. In other words, the first control unit 100 draws map information representing roads and the like on the touch panel 110 while sequentially detecting the position of the vehicle by GPS or autonomous navigation in response to the user's selection to start guidance. Use images and voice to guide you to the destination.

The instruction input such as designation and selection by the user is triggered by the first control unit 100 detecting that the first control unit 100 has touched the button 140 displaying the name of the item or function on the touch panel 110 or the icon of the facility. can be done as
<Example of implementation>
The integrated device 1000 described above can be mounted in an electronic device as follows, for example.

18A and 18B are six views showing an example of the appearance of an electronic device in which the integrated device 1000 is mounted. In FIG. 18, the front view is shown in the second stage of the center row. Here, in FIG. 18, the front view is the surface facing the touch panel 110 when the integrated device 1000 is installed. A touch panel 110 is arranged on the front of the integrated device 1000 . Also, the bezel surrounding the touch panel 110 does not have the buttons 140 or the like arranged thereon, so that the touch panel 110 is not obstructed.

A left side view is shown to the left of the front view. A first storage unit 180, an informing LED 130b, and a USB terminal 320 are arranged on the left side of the integrated device 1000. As shown in FIG. The first storage unit 180 is implemented by an SD slot, into which an SD card as a storage medium is inserted. The notification LED 130b is an LED that indicates whether or not power is being supplied, and lights green, for example, during power supply. A cigar plug cord 504 is connected to the USB terminal 320, and the integrated device 1000 receives power from the car charger via the cigar plug cord 504 as described in the <Battery Control> section. In order to clarify the shape of the integrated device 1000, FIG. 17 omits illustration of the cord portion extending from the socket of the cigar plug cord.

A right side view is shown to the right of the front view. A second storage unit 230 is arranged on the right side of the integrated device 1000 . The second storage unit 230 is implemented by an SD slot, into which an SD card as a storage medium is inserted.

A top view is shown above the front view. A notification LED 130a, a button 140a, a button 140b, and a button 140c are arranged on the upper surface of the integrated device 1000. As shown in FIG. The notification LED 130a is used to indicate whether or not constant recording is being performed by the integrated device 1000. For example, it lights red when constant recording is not being performed. A button 140a is a button 140 for starting manual recording, and event recording is started when the button 140a is pressed. A button 140b is a button 140 for stopping or restarting constant recording, and the constant recording is stopped or resumed each time the button 140b is pressed. A button 140c is a button 140 for turning the integrated device 1000 on or off. The body shaping apparatus 1000 is powered on.

The rear view is shown in the third row of the central row. A camera 210 and a joint part 502 are arranged on the rear surface of the integrated device 1000 . Edge 501a, edge 501b, edge 501c and edge 501d are formed on the rear surface of integrated device 1000. FIG. The camera 210 unit is incorporated into the integrated device 1000 through a ball joint, and the camera 210 is movable. Assume that the range of motion of the camera 210 is, for example, 15 degrees in each direction. That is, if the camera 210 is in the center, it can be moved upward by 15 degrees and downward by 15 degrees. The joint part is a part for attaching the integrated device 1000 to a cradle for fixing the integrated device 1000 . Edge 501a, edge 501b, edge 501c and edge 501d are ridge lines formed on the back surface. Edge 501a, edge 501b, edge 501c, and edge 501d are curved and have a shape that does not get caught in the hand of the user carrying integrated device 1000. FIG.

A bottom view is shown in the third row of the center row. A speaker slit 503 is provided on the bottom surface of the integrated device 1000 . A speaker slit 503 is a slit through which the sound output by the speaker 120 of the integrated device 1000 is output. Details of the speaker slit 503 and the speaker 120 will be described later.

Here, as described above, the integrated device 1000 has four surfaces on the rear surface by providing the four ridge lines of edge 501a, edge 501b, edge 501c, and edge 501d. Also, as can be seen from the bottom view, top view, left side view, and right side view, for example, the camera 210 is the apex, and each end of the rear surface is inclined downward.

In this respect, it is also conceivable to make the housing of the integrated device 1000 a flat rectangular shape by making the thicknesses of the respective end portions and the camera 210 portion equal without providing such an inclination. However, such a shape makes the entire integrated device 1000 large and lacks portability.

Also, the reason why the camera 210 portion becomes thicker and the camera 210 portion becomes the top is due to the size of the camera 210 unit forming the camera 210 . Therefore, the camera 210 portion cannot be made thin. On the other hand, other circuitry can be thin compared to the camera 210 portion. Therefore, even if the thickness of each end portion and the camera 210 portion are made equal, only wasted space is generated in the housing of the integrated device 1000 . From this point of view as well, the housing of the integrated device 1000 need not be flat and rectangular.

Therefore, in this implementation example, the camera 210 is the apex, and each end of the back surface is inclined downward, thereby reducing the thickness of the back surface. As a result, it is possible to prevent the case from becoming unnecessarily thick, impairing the portability, and the occurrence of wasted space in the housing.

Other features of this implementation will also be described with reference to FIG. The left side of the integrated device 1000 is shown in FIG. 19(a). As described with reference to FIG. 18, the USB terminal 320 for connecting the cigar plug cord 504 is arranged on the left side of the integrated device 1000 . A notch 505 is formed in the right half of the USB terminal 320 when viewed from the left side. Here, when viewed from the left side, the notch 505 is substantially vertical from top to bottom up to the height at which the USB terminal 320 is provided. The lower part has a shape that curves to the left as if drawing an arc.

19(b) shows the rear surface of the integrated device 1000. As shown in FIG. When viewed from the back, the notch 505 has an upper portion (for example, approximately two-thirds of the entire length) and a lower portion (for example, approximately one-third of the entire length) with different left and right lengths. ing. Specifically, the left and right lengths of the lower portion are shortened.

The reason why the notch 505 has such a shape will be described with reference to FIG. 19(c). FIG. 19(c) is a left side view showing a state where the cigar plug cord 504 is attached to the USB terminal 320. FIG. Referring to FIG. 19(c), a cigar plug cord 504 and a cord portion 504-1 extending from the cigar plug cord 504 are shown.

First, as described with reference to FIG. 19(b), the notch 505 when viewed from the rear side has shorter left and right lengths at the lower portion, corresponding to the thickness of the cable. ing. Therefore, when viewed from the rear side, the cord portion 504-1 follows the shape of the notch 505 without shifting to the left or right. When the cord portion 504-1 is viewed from the left side of the notch 505, the cord portion 504-1 hangs along a shape that curves to the left like drawing an arc. In other words, the shape of the notch 505 that curves to the left like an arc when viewed from the left side guides the cord portion 504-1 of the cigar plug cord 504 in a desired direction rather than causing it to hang down.

By doing so, it is possible to prevent the code portion 504-1 from moving in an unintended direction. Also, since the arc is drawn, the cord can be prevented from being bent at an acute angle. This makes it possible to extend the life of the cord.

Further, the left and right width of the notch 505 when viewed from the back of the integrated device 1000 is such that the cigar plug cord 504 and the cord portion 504-1 are not visible to the user when viewed from the front of the integrated device 1000. do it. As a result, only the rectangular shape of the front surface of the integrated device 1000 is visible to the user, creating a sense of unity.

Furthermore, if the left and right width of the notch 505 when viewed from the back of the integrated device 1000 is set to the width where the cigar plug cord 504 and the cord portion 504-1 can be seen from the user when the integrated device 1000 is viewed from the front. good. This allows the user to confirm that the cigar plug cord 504 is connected to the USB terminal 320 .

Other features of this implementation will also be described with reference to FIG. FIG. 20 is a rear view of the integrated device 1000 and shows the shape when the rear portion of the cover that realizes the housing of the integrated device 1000 is removed.

FIG. 20 shows a speaker unit 506, a speaker holding portion 507, and a speaker slit corresponding position 508 representing a position corresponding to the position of the speaker slit 503. FIG.

The speaker unit 506 corresponds to the speaker 120 in FIG. 1, and generates sounds such as operation guide voices, warning sounds, and music using a diaphragm. Here, generally, a sound emitting hole is provided in a portion corresponding to the speaker unit 506 on the rear surface of the cover that realizes the housing of the integrated device 1000, for leading out the sound generated by the diaphragm to the outside of the cover.

However, in this implementation example, it is assumed that the integrated device 1000 is carried, and it is conceivable that the user will see the back side. In such a case, if a sound emitting hole is provided, the external appearance is spoiled.

Therefore, in this implementation example, the speaker holding unit 507 not only holds the speaker unit 506 but also surrounds the speaker unit 506 . However, the lower part of speaker unit 506 does not surround speaker unit 506 . As a result, the sound generated by the diaphragm is guided from the lower portion of the speaker unit 506 to the speaker slit corresponding position 508 , and finally extracted from the speaker slit 503 . This makes it possible to output sound to the outside without providing a sound emission hole in the portion corresponding to the speaker unit 506 on the back of the cover that realizes the housing of the integrated device 1000 . Accordingly, it is possible to prevent the appearance from being spoiled by the sound emission hole.

Next, referring to FIG. 21, a diagram of a state in which the integrated device 1000 is attached to the cradle 2000 and the base portion 3000 in order to fix the integrated device 1000 to a dashboard or the like will be described. In this implementation example, the cradle 2000 is detachable from the joint portion 502 shown in FIG. Use as

Cradle 2000 is further connected to base 3000 . The pedestal part 3000 is
Support the cradle 2000 in any posture. The pedestal 3000 is fixed by suction on a dashboard or the like with a suction cup, a suction sheet, or the like provided on the bottom surface. The base portion 3000 and the cradle 2000 are rotatably connected within a predetermined angular range via a connecting mechanism such as a ball joint. Since it is a ball joint, the pedestal 3000 and the cradle body 2000 can rotate relative to each other within an arbitrary three-dimensional angular range and remain in an arbitrary angular position due to frictional resistance at the joint. Therefore, the integrated device 1000 attached to the cradle 2000 can also be arranged in any posture on the dashboard.
<Modification>
The above-described embodiments and implementation examples are preferred embodiments of the present invention, but the scope of the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the present invention. You may make it implement in the form which carried out.

For example, in the above-described embodiment, the shape of the icon displayed on the map is changed according to the presence or absence of the video file. Also, the color of the icon displayed on the map was changed according to the level of the event. Furthermore, numbers were assigned to the events in chronological order, and their order was displayed numerically. In other words, the display mode of each icon is varied according to such conditions. Here, different display modes include, for example, different icon colors, shapes, sizes, number displays, and the like.

In this respect, the manner in which the display mode is made different and the correspondence between the conditions for making the display mode different are not necessarily limited to the above-described embodiments. For example, it is preferable to change the color of the icon displayed on the map according to the presence or absence of the video file. Moreover, it is good to make both a color and a shape different. For example, the number of icons displayed on the map may be changed according to the level of the event. Also, if there are a first condition such as the presence or absence of a video file and a second condition such as an event level, the display mode may be changed differently depending on the conditions.

For example, it is good not to delete the oldest file when performing continuous recording. As a result, new real-time video cannot be saved, but old real-time video can be prevented from being erased.

Also, it is preferable to start and stop continuous recording in conjunction with the supply of power. As a result, continuous recording can always be performed without user's operation.

Furthermore, in manual recording and event recording, the oldest file may not be deleted even if a new event occurs or a user's operation is performed. As a result, new files cannot be protected, but previously protected files can be prevented from being deleted.

Furthermore, even files protected by manual recording and event recording may be deleted according to user operations and settings. As a result, it becomes possible to increase the free space of the storage section by deleting files that are deemed unnecessary after confirming their contents.

Furthermore, in the list of icons such as i13, the event icon or history icon pressed on the map may be placed at the top of the list. It is also possible to rearrange the events in chronological order based on the date and time when the event occurred.

Furthermore, when the first recording unit and the second storage unit 230 can use the same type of storage medium, for example, when the capacity of the storage medium used in the second storage unit 230 becomes maximum In addition, it is also possible to replace the storage medium used in the first storage unit 180 and use it. This makes it possible to use the two storage media properly according to the situation. Also, by inserting the storage medium storing the video file into the first storage unit 180 by the second control unit 200, the video file can be reproduced by the first control unit 100. FIG.

Furthermore, when it is determined that an event has occurred, it is preferable to perform control so as not to execute a function that hinders real-time video imaging. The function that hinders real-time video imaging is, for example, the audio output function of a television. By doing this, when image data is captured, the TV sound is stopped at least after it is determined that an event has occurred, and it is possible to prevent the TV sound from being mixed with the captured data.

Furthermore, when it is determined that an event has occurred, event recording may not be performed even if the measured value of the acceleration sensor 170 exceeds any of a plurality of threshold values. As a result, for example, when it is frequently determined that an event has occurred based on a slight impact, the video file is not stored even if it is determined that an event has occurred based on a slight impact. Therefore, it is possible to prevent a situation in which the capacity of the storage medium is quickly exhausted due to an excessive increase in the number of video files. For example, depending on the vehicle type, road conditions, driving habits, etc., if it is often determined that an event with the most sensitive threshold has occurred, recording every time will overwrite the important recorded data immediately. . Therefore, in such a case, for example, even if it is determined that an event with the most sensitive threshold value has occurred, it is preferable not to store the video file.

Furthermore, since the camera 210 is movable, it is preferable that one or both of the incidence position and direction of the incidence portion 211 of the camera 210 can be adjusted. This makes it possible to adjust the incident position even after the vehicle-integrated device 1000 is installed. As a result, the range to be imaged can be adjusted so as to correspond to the shape and installation position of the automobile, and image data of a desired range can be imaged.

Furthermore, the threshold value for determining that an event has occurred can be set to a different value for each measurement axis. good too. By doing so, it is possible to use a threshold according to the usage status of the integrated device 1000, and to prevent erroneous determination that an event has occurred when no event has occurred. becomes.

In this regard, depending on how the integrated device 1000 is used, the value measured by the acceleration sensor 170 may increase in a predetermined direction regardless of the occurrence of an event. For example, when the front surface of the integrated device 1000 is the touch panel 110, when the user presses the touch panel 110, the acceleration sensor 170 measures in the measurement axis corresponding to the direction from the front surface to the rear surface of the integrated device 1000. value goes up. Since this has nothing to do with event occurrence, it is preferable not to judge that an event has occurred in such a case.

Therefore, for example, it is preferable to increase the threshold in the measurement axis corresponding to the direction from the front surface to the rear surface of the integrated device 1000 . For example, when installing the integrated device 1000 in an automobile, the front surface of the integrated device 1000 provided with the touch panel 110 faces the front of the user, and the rear surface of the integrated device 1000 faces the traveling direction of the automobile. Therefore, for example, when the traveling direction of the automobile is the front, the measurement axis corresponding to the traveling direction of the automobile is the X direction (front and back), and when the traveling direction of the automobile is the front, the measurement axis corresponding to the left and right of the automobile is the Y direction (left and right). ), the Z direction (left and right) is the measurement axis corresponding to the top and bottom of the vehicle when the traveling direction of the vehicle is forward, and the threshold for the measurement axis in the X direction (front and rear) is set high.

This makes it possible not to determine that an event has occurred even if some impact is detected.

Furthermore, even if the measured value of the acceleration sensor 170 exceeds the threshold, if the threshold is exceeded during a predetermined period including the time when an operation is accepted by the touch panel 110, it is not considered that an event has occurred. It is better to As described above, for example, in the measurement axis corresponding to the front-to-back direction of the integrated device 1000, the measured value by the acceleration sensor 170 rises. Since this has nothing to do with event occurrence, it is preferable not to judge that an event has occurred in such a case. Therefore, if it is during a predetermined period including the time when the operation is accepted, it is not assumed that the event has occurred. As a result, even if the acceleration sensor 170 measures the impact caused by the operation, it is possible to prevent an erroneous determination that an event has occurred based on this. In such a case, it is determined that an event has occurred, and event recording is performed. However, for example, it is preferable not to output a pop-up display or warning sound to the effect that an event has occurred. As a result, it is possible to prevent a situation in which a warning is output even though the acceleration sensor 170 measures the impact associated with the operation and erroneously determines that an event has occurred.

It is preferable to restrict at least part of the functions executed by the integrated device 1000 to be controlled by the integrated device 1000 when the vehicle is located near the location where the event occurred. By doing so, the user can concentrate on driving the car at the location where the event occurred last time. In many cases, it is desired to drive carefully in a place where an event has occurred in the past. For example, assume that there is a place where it is determined that an event has occurred because the driver suddenly applied the brakes to avoid an accident or the like last time. In this case, the function of the integrated device 1000 to be controlled is partially restricted in the vicinity of this location. For example, it is good to limit the audio output function of the TV. By doing this, it is possible to stop the output of the TV sound that interferes with driving near the place where the driver suddenly applied the brakes to avoid an accident, etc., and the user can concentrate on driving the car. becomes.

Furthermore, it is preferable to output, for example, the moving speed of the vehicle as measurement information other than the acceleration measured when the event occurs. By doing so, the user can prove, for example, that the speed was below the legal speed limit when the event occurred, or that the user was properly slowing down. The moving speed of the automobile can be calculated by using GPS position information, for example. It may also be possible to obtain the travel speed of the vehicle, for example by using OBD (On-board diagnostics).

In the above description, the event icon and the history icon are displayed on the map including the current position of the vehicle in which the integrated device 1000 is installed. In other words, it has been explained that a map of the vicinity of the automobile is displayed. In addition to this, when searching for a route or a destination, it is preferable to display event icons and history icons for manual recording and event recording that occur around the route and the destination. This allows the user to refer to icons for locations that do not include the current position of the car.

Furthermore, it is also possible to provide operation guidance to the position of the event icon or history icon in response to pressing of the event icon or history icon. By doing so, it is possible to easily revisit a place where an accident occurred in the past, a place where an event occurred frequently, or a place where the user manually recorded.

Furthermore, the information for navigation stored in the main storage unit 190 may store all information about the whole country at the time of shipment. Further, the map data and the like are stored in a storage medium for each region, and the user prepares a storage medium in which necessary map data and the like is stored and loads it into the first storage unit 180. You may use Note that the map data and the like stored in the storage medium may be transferred to the main storage unit 190 and stored. Alternatively, the first control unit 100 may access the storage medium and read out from the storage medium for use.

In the above-described embodiment, three storage units such as the main storage unit 190, the first storage unit 180, and the second storage unit 230 are provided, but it is not always necessary to provide three storage units. For example, the first control unit 100 may not be provided.

In the above-described embodiment, the software for realizing the control by the first control unit 100 is stored in the main storage unit 190. may be stored in a ROM included in the control unit 100 of the controller.

The threshold may be adjustable by the user, but in view of the fact that the user generally does not know how much to adjust the threshold, the threshold may be fixed. This makes it possible to prevent the user from setting an inappropriate threshold value.

In the above description, each icon is not only displayed in different colors, but also, for example, as a circled number including numbers in chronological order. At this time, the numbers may be assigned in descending or ascending order along the time series. That is, the number of the newest icon may be 1, and the number of the oldest icon may be 10. Alternatively, the number of the newest icon may be 10, and the number of the oldest icon may be 1.

In the above description, the video file was reproduced via the first control unit 100, but it is also possible to output the video file directly from the second control unit 200 to the touch panel 110. FIG. Also, the process of decoding two video files into image data may be performed by the first control unit 100 instead of the second control unit 200 .

In the above description, the [shortcut] button 140 may be associated not with "camera image" but with "television image". The user may refer to the "camera image" when installing the integrated device 1000, but may refer to the "television image" after the installation.

Further, even when the [Shortcut] button 140 is pressed to transition to the screen S3, it is preferable to continue the operation guidance by voice. As a result, it is possible to prevent the inconvenience that the operation guidance is interrupted.

Also, a button 140 for accepting an operation that triggers manual recording may be displayed on the screen, that is, on the touch panel 110 . Further, it is preferable that the button 140, which is a hard key, not the button 140 displayed on the touch panel 110 is used to receive an operation that triggers manual recording. Since this eliminates the need to provide the button 140 on the touch panel 110, it is possible to prevent a part of the real-time video displayed on the screen S13 from being partially hidden by the button 140, for example. .

In the explanation of FIG. 14, step A3 is performed and then step A4 is performed, but if it is within the range of the rated current of the cigar plug cord, steps A3 and A4 may be performed at the same time. This makes it possible to shorten the time until the second control unit 200 is activated.

Furthermore, the acceleration detected by the acceleration sensor 170 differs depending on factors such as the individual's driving style, vehicle type, and roads on which the vehicle is usually traveled. Therefore, in some cases, the threshold used as a criterion for determining that an event has occurred may be too low. In this case, there is a possibility that the occurrence of an event may be erroneously detected even though the event has not occurred. On the other hand, depending on the circumstances, the threshold used as the criterion for determining that an event has occurred may be too high. In this case, although an event has occurred, it may be erroneously detected that the event has not occurred.

Therefore, it is preferable to allow the user to modify the threshold set at the time of shipment. Further, in this embodiment, a plurality of thresholds are provided, and the colors of the icons displayed on the map are changed according to which threshold the acceleration detected by the acceleration sensor 170 exceeds. By doing so, the user can use the icons with different colors as a guide when setting individual differences in the threshold due to personal driving style, vehicle type, roads on which the vehicle is usually traveled, and the like.

Moreover, if it is considered difficult for the user to set the threshold, it is preferable to prevent the user from correcting the threshold that is set at the time of shipment.

Furthermore, when an SD card or the like is inserted as a storage medium into the second storage unit 230, the number of video data that can be saved is limited according to the storage capacity of the SD card. I can't watch videos. However, it is preferable to distinguish between the latest file in which moving image data is saved and the older file in which moving image data is not saved. The distinction may be realized by, for example, changing the shape or color of the icon. For example, the number of the latest files should be 10.
