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.

In recent years, it has become common to use a car navigation device that provides operation guidance to a user who uses a moving body such as an automobile.

For example, Patent Document 1 describes a position detecting means for detecting the current position of the own vehicle by performing positioning using GPS (Global Positioning System), a storage unit for storing road type information, and an image display. A car navigation device including a display unit for performing the above is described.

Then, the car navigation device 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 information of the road, and the like, and the created information for operation guidance. Is displayed on the display unit in combination with the map information. This allows the user to reach the destination via an appropriate route.

On the other hand, for the purpose of analyzing the situation at the time of an accident, a drive recorder is also being installed on a moving body such as an automobile.

The drive recorder stores, for example, a camera for taking an image of the surroundings of the vehicle, an acceleration sensor for detecting an abnormality such as a collision accident, sudden braking, or sudden steering, and image data acquired by the camera taking an image. It has a medium.

Then, the camera constantly memorizes the surrounding image while traveling. Further, when an abnormality such as a collision accident, sudden braking, or sudden steering is detected based on the output from the acceleration sensor, the image data for a predetermined time before and after that point is stored in a storage medium. As a result, the user can check the surroundings of the vehicle when an abnormality such as a collision accident, sudden braking, or sudden steering wheel occurs. An example of such a drive recorder is described in, for example, Patent Document 2.

Further, the image data stored in the storage medium by the drive recorder in this way can be reproduced by inserting the storage medium into a reproduction device for reproduction such as a personal computer. It is also possible to display the location where the image data is stored on the map by inserting the storage medium into a playback device for playback such as a personal computer.

Japanese Unexamined Patent Publication No. 2013-160679 Japanese Unexamined Patent Publication No. 2013-235395

As described above, when driving an automobile or the like, devices such as a car navigation device and a drive recorder are used. Further, for example, a playback device such as a personal computer is used to reproduce the image data stored in the storage medium by the drive recorder.

While some of these devices have overlapping functions, such as having a display function, the car navigation device has a positioning function and a function for operation guidance using map information, etc. , The drive recorder has a shooting function and a measurement function by an accelerometer, and the external device has a function to play back the image data saved in the storage medium by the drive recorder and display the location where the image data is stored on the map. Each had its own function, such as having a function.

However, the car navigation device, drive recorder, and playback device are realized as separate devices, and the devices used in these mobiles and the devices used after using the mobiles have these unique functions. It was not supposed to be used in cooperation.

Therefore, an object of the present invention is to provide an apparatus and a program capable of coordinating and using functions implemented in separate devices.

(1-1) The measurement information that changes with the movement of the moving body becomes the information that satisfies any one of a plurality of conditions provided in stages (hereinafter referred to as "an event has occurred"). If you do)
It is characterized in that two pieces of information, information for specifying the place where the event has occurred and information indicating which of the plurality of conditions provided in stages are satisfied, are associated and output for each event. The device to be.

By doing so, not only the device concerned, but also "the event was determined to have occurred", "the place where the event occurred", and "which of the multiple conditions was satisfied, the event occurred. It is good because it is possible to obtain "whether it was determined that the event was done" at the output destination.

(1-2) When the event occurs, control for storing the two pieces of information or control for storing the two pieces of information is performed.
When a predetermined output condition is satisfied, the two pieces of information that are stored or stored are associated with each event and output.

By doing so, it becomes possible to read and use these two pieces of information when it becomes necessary to use these two pieces of information later, regardless of whether the information is stored or stored. .. Further, in the former case, even when the storage medium inserted in the device is removed, these two pieces of information can be read and used. Further, in the latter case, for example, when the writable capacity of the storage medium inserted in the device is full, it is possible to replace it with a new storage medium and use it.

As a control for storing the two pieces of information, for example, it is preferable to write these two pieces of information in a storage unit included in the device itself. The control for storing the two pieces of information may be such that the two pieces of information are written in, for example, a storage medium inserted in the device or a storage device connected to the device.

(1-3) The predetermined output conditions are that the moving body approaches the place where the event has occurred and that information related to the place around the event occurrence including the place where the event has occurred is output. It is characterized by being either or both of.

In this way, the predetermined output condition, which is the condition for outputting information, is that the moving body approaches the place where the event occurs, so that the moving body approaches the place where the event occurred in the past during the operation of the moving body. In some cases, it is possible to output information about events that have occurred in the past. Further, by setting the output destination to, for example, a display unit or a speaker, it can be understood that the user is currently approaching a place where an event has occurred in the past.

In addition, by outputting the information related to the event occurrence peripheral location including the event occurrence location, the information related to the event occurrence peripheral location is output by setting the predetermined output condition which is the condition for outputting the information in this way. When you do, you can output information about events that have occurred in the past. Further, to output the information related to the place around the event occurrence including the place where the event occurred, it is preferable to output the peripheral map including the place where the event occurred. By doing so, for example, when a user using the car navigation function searches for a route, past event occurrence locations existing on the route can be output together with a map of the surrounding area.

(1-4) When the event occurs, the image data captured at the time of the event occurrence, before the event occurrence, after the event occurrence, or a combination of two or more thereof is stored. It is characterized in that the image data can be reproduced after the event occurs by performing the control for the purpose or the control for storing the image data.

By doing so, for example, since the image data taken during a certain period before and after the event occurs can be stored, the image data taken during a certain period before and after the event can be reproduced. Further, since there is a combination of two or more of these, it is preferable to use a combination such as a fixed period at the time of event occurrence and before the event occurrence, or a fixed period at the time of event occurrence and after the event occurrence. Further, the image data may be a still image. It is also good to use the image data as a moving image. Further, the image data may include data other than still images and moving images. For example, the image data may include audio data.

Further, the image data may be generated by imaging by an imaging means. The imaging means and the device may be connected. Further, a device included in the same housing as the device may be controlled by the device. Then, the device to be controlled may include an imaging means.

Further, the control for storing or the control for storing may be performed in the same manner as the writing of the two pieces of information described in the item (1-2), for example.

(1-5) In addition to the above two pieces of information, the stored image data or the information indicating the existence of the stored image data is also output in association with each other.

At the output destination, it is possible to grasp which event the corresponding image data exists. In addition, for example, by setting the output destination to a display unit or a speaker, the user who refers to the output information can add "where the event occurred, etc., and" the image data corresponding to the event can be currently reproduced. It is also possible to grasp "whether it is in a state".

(1-6) When it is determined that the event has occurred, control is performed so that the function to be executed by the device to be controlled by the device and which hinders the imaging of the image data is not executed. It is characterized by.

By doing so, it becomes possible to capture the image data without any obstacles. For example, a device controlled by the device is a device capable of reproducing a television image, and a function executed by the device controlled by the device that hinders the acquisition of image data is a television sound. It should be an output function. By doing so, when the image data is captured, the television sound is stopped at least after it is determined that an event has occurred, and it is possible to prevent the television sound from being mixed with the image data. Further, for example, the device to be controlled by the device may be a wiper of an automobile, and the function executed by the device to be controlled by the device and which hinders the imaging of the image data may be the operation of the wiper. .. By doing so, when the image data is captured, the operation of the wiper is stopped at least after it is determined that an event has occurred, and it is possible to prevent the operating wiper from being reflected in the image data.

(1-7) It has a deletion function for deleting the image data that is stored or stored.
Even if the image data corresponding to a certain event becomes unreproducible due to being deleted by the deletion function, information for specifying the place where the certain event occurred and the stepwise provision are provided. It is characterized in that two pieces of information indicating which of the plurality of conditions are satisfied are output.

By doing so, two pieces of information can be output even after the image data has been deleted. Further, these two pieces of information can be used at the output destination. Therefore, even if the image data is deleted and the image data cannot be reproduced, the user can check the place where the event occurred and the degree of impact when the event occurs.

(1-8) When the first condition among the plurality of conditions is satisfied, the control for storing the image data or the control for storing the image data is performed.
When the second condition among the plurality of conditions is satisfied, the control for storing the image data or the control for storing the image data is not performed, but the place where the certain event occurs is specified. It is characterized in that two pieces of information, the information to be output and the information indicating which of the plurality of conditions provided in stages are satisfied, are output.

In this way, even if any of the plurality of conditions is satisfied, it is preferable not to store the image data. As a result, for example, when it is frequently determined that an event has occurred based on a slight impact, the image data is not stored even if it is determined that an event has occurred based on a minor impact. Therefore, it is possible to prevent a situation in which the image data increases too much and the capacity of the storage medium is used up immediately. For example, depending on the vehicle type, road conditions, driving habits, etc., if it is frequently judged that an event with the most sensitive threshold has occurred, recording each time will overwrite the important recorded data immediately. .. Therefore, in such a case, for example, even if it is determined that an event at the most sensitive threshold value has occurred, it is preferable not to store the image data. Further, in this case, since the image data is not stored but the two pieces of information are output, the user can confirm the place where the event occurs and the degree of impact when the event occurs.

(1-9) Control is performed to display a symbol that identifies the place where the event occurs, and control is performed to change the display mode of the symbol depending on whether or not the image data is stored. It is characterized by doing.

By doing so, the information to be output can be visualized, and for example, a user who refers to the information can grasp the content of the information. Specifically, the user who refers to the symbol can grasp not only the place where the event occurred but also which event the image data is stored in. Here, the specific shape of the symbol is arbitrary, but for example, it may be an icon for displaying the symbol on a map. As a result, the user can refer to the map by comparing the location where the event occurred, so that it is possible to easily recognize where the event occurred.

Further, how to make the display mode of the symbol different is also arbitrary. For example, a round icon is used as a symbol for specifying the place where the event in which the image data is stored occurs, and the image data is stored. As a symbol for identifying the place where an unmemorized event occurs, a rectangular icon may be used. Further, it is preferable that the color is different between the symbol for specifying the place where the event occurs and the symbol for specifying the place where the event where the image data is not stored occurs. Further, it is preferable that both the shape and the color of the icon are different between the symbol for specifying the place where the event occurs and the symbol for specifying the place where the event for which the image data is not stored occurs.

(1-9-1) The size of the symbol that identifies the place where the event in which the image data is stored occurs is larger than the size of the symbol that specifies the place where the event in which the image data is not stored occurs. It is characterized by performing control for displaying as a large one.

By doing so, the information to be output can be visualized, and for example, a user who refers to the information can grasp the content of the information. Here, the symbol is the same as (1-9) described above, and for example, the symbol may be an icon for displaying on the map.

Further, how to make the shape of the symbol different is also arbitrary, but for example, as a symbol having a certain size as a symbol for specifying the place where the event in which the image data is stored occurs. As a symbol for specifying the place where the event in which the image data is not stored occurs, a round icon smaller than a certain size may be used.

Further, by combining with (1-9) described above, both the size of the icon and the shape of the icon may be made different.

In any case, the user who refers to this can grasp not only the event occurrence location but also which event the image data is stored in.

(1-10) It is necessary to accept an operation for controlling to stop the imaging of the image data at the time of reproducing the image data and to restart the imaging of the image data after the reproduction of the image data is completed. It is characterized by doing without.

By doing so, it is possible to prevent a situation in which the image data being reproduced is overwritten when it is determined that a new event has occurred during the reproduction of the image data.

Further, for example, in the case where a number is assigned to each image data and managed as a list, and when it is determined that a new event has occurred during image data reproduction, it is assigned to new image data. It is possible to prevent a situation in which the number and the number assigned to the image data being reproduced are duplicated. For example, if the recorded data currently being played is managed as the latest image data and new image data is generated, which data is the latest data is managed after the end of playback. It is possible to prevent a situation in which it becomes impossible.

Further, after preventing such a situation, by restarting the image data imaging without requiring the acceptance of the operation, the recording is restarted even if the user forgets the operation for starting the recording. It becomes possible. In addition, it is possible to save the trouble of the user performing the operation.

(1-11) The device to be controlled by the device is provided with an imaging means for capturing the image data.
Even after the device to be controlled is installed in the moving body, the incident portion that incidents light on the imaging means can be moved so that either or both of the incident position and the direction of the incident portion can be adjusted. And.

By doing so, it is possible to adjust the incident position even after the device to be controlled is installed on the moving body. As a result, the range to be imaged can be adjusted so as to correspond to the shape and installation position of the moving body, and the image data in a desired range can be captured. A device included in the same housing as the device may be controlled by the device. Then, the device to be controlled may include an imaging means. The imaging means may be, for example, a camera, and the incident portion may be, for example, a camera lens.

(1-12) Control is performed to display a symbol that identifies the place where the event occurs, and the symbol is determined according to which of the plurality of conditions provided in stages is satisfied. It is characterized in that control is performed to make the display mode of the above different.

By doing so, it is possible to visualize the information to be output, for example, the user who refers to this can grasp which condition each event is judged to have occurred. It will be possible. Here, the symbol is the same as the above-mentioned (1-9) and (1-9-1), and for example, the symbol may be an icon for displaying on the map.

In addition, it is optional to use what color to make the color of the symbol different, but for example, if it is judged that an event has occurred due to a minute impact, the event will be green. You should do it. Further, for example, when it is determined that an event has occurred due to a large impact, the event may be red. Further, for example, when it is determined that an event has occurred due to an impact between these minute impacts and a large impact, the event may be yellow. Further, the size and shape of the icon may be different depending on the magnitude of the impact.

Further, by combining with the above-mentioned (1-9) and (1-9-1), both the size and the icon shape of the icon may be made different depending on the presence or absence of image data.

Further, when associating with the above-mentioned configurations (1-9) and (1-9-1), it is advisable to make them different depending on the content. For example, the "shape" of the icon may be different depending on the presence or absence of image data, and the "color" of the icon may be different depending on the magnitude of the impact. Further, it is preferable to make the "color" of the icon different depending on whether or not the image data exists, and to make the "shape" of the icon different according to the magnitude of the impact.

(1-13) With the reception of the predetermined operation as an opportunity, control for storing the information specifying the place where the predetermined operation is received separately from the information specifying the place where the event occurs, or Control is performed to store the information that identifies the place where the predetermined operation is received separately from the information that specifies the place where the event occurs.
It is characterized in that the symbol for specifying the place where the operation is received is controlled to be displayed in a display mode different from the symbol for specifying the place where the event has occurred.

As a result, it is possible to memorize (store) the position information even when it is not determined that the event has occurred. Then, by doing so, the information to be output can be visualized, and therefore, the user who refers to this can distinguish between the place where the event is determined to occur and the place where the operation is performed. It becomes possible.

Here, the symbol is the same as the above-mentioned (1-9), (1-9-1) and (12), and for example, the symbol may be an icon for displaying on the map.

Further, it is arbitrary to use what kind of color to make the color of the symbol different, but for example, the symbol that specifies the place where the operation is accepted may be blue characters.

Further, by combining with the above-mentioned (1-9) and (1-9-1), both the size and the icon shape of the icon may be made different depending on the presence or absence of image data. Furthermore, by combining with (1-12) above, it is also possible to make the color of the icon different depending on which condition each event is judged to have occurred. Good.

Further, the control for storing or the control for storing may be performed in the same manner as the writing of the two pieces of information described in the item (2), for example.

(1-14) The output information is characterized in that it further includes information for indicating the order in which the events are determined to have occurred.

By doing so, it becomes possible to grasp at the output destination which event is determined to have occurred recently and which event has been determined to have occurred in the past.

For example, it is preferable to overwrite and delete the image data of the old event. In this case, by setting the output destination of the information to the display unit, the user can know which event data will disappear soon. Therefore, it is possible to preferentially reproduce the data that is likely to disappear.

Further, it may be combined with the above-mentioned (1-9), (1-9-1), (1-12) and (1-13).

For example, in combination with (1-9-1) described above, for example, the icon may be a circled number indicating a number in chronological order.

(1-15) The measurement information that changes with the movement of the moving body includes the measured value by the acceleration sensor, and the plurality of measurement information depends on which of the thresholds provided in stages the measured value by the acceleration sensor exceeds. It is characterized in that it is determined which of the conditions is satisfied.

By doing so, the user can determine not only that the moving body collided with another moving body or an installed object, but also how much the impact was at the time of the collision.

(1-16) Even if the measurement information that changes with the movement of the moving body is information that satisfies any one of a plurality of conditions provided in stages, the information is satisfied. If it is during a predetermined period including when the operation is accepted, it is determined that the event has not occurred or the event has occurred, but a warning that the event has occurred is output. It is characterized in that it does not control.

The operation is an operation by the user, and there is a risk of erroneously determining that an event has occurred based on the impact of accepting this operation. However, by doing so, it is possible to prevent the event from being erroneously determined to have occurred when the event has not occurred.

Depending on the usage status of the device, the value measured by the accelerometer may increase in a predetermined direction regardless of the occurrence of the event. For example, when the front surface of the device is a touch panel, the user presses the touch panel, so that the measured value by the acceleration sensor increases on the measurement axis corresponding to the direction from the front surface to the rear surface of the device. Since this has nothing to do with the occurrence of the event, it is better not to judge that the event has occurred in such a case.

Therefore, it is not considered that the event has occurred if it is during a predetermined period including when the operation is accepted. As a result, even when the acceleration sensor measures the impact caused by the operation, it is possible to prevent an erroneous determination that an event has occurred based on the measurement.

However, there may be cases where an event actually occurs before and after the operation. Therefore, instead of not determining that an event has occurred, it is better to determine that an event has occurred but not output a warning. As a result, it is possible to reliably perform the processing performed when the event occurs. The processing performed in response to the occurrence of an event may be, for example, storage processing of image data. On the other hand, it is possible to prevent a situation in which a warning is output even though the acceleration sensor measures the impact caused by the operation and makes an erroneous judgment that an event has occurred. ..

(1-17) The device to be controlled by the device includes a first storage medium use unit and a second storage medium use unit, and the storage medium used in one of the storage medium use units can be used. It is characterized in that it is controlled so that it can be used in the other storage medium usage unit.

By doing so, it becomes possible to effectively use the two storage medium use units.

For example, it is preferable that the device to be controlled has a substrate that realizes two functions, and each of these substrates can use a storage medium conforming to the same standard. This makes it possible to use the same storage medium on each other's substrates.

For example, a board that realizes the function of a car navigation system and a board that realizes the function of a drive recorder may be used. For example, when image data taken on a board that realizes the function of a drive recorder is reproduced by the ability of the board that realizes the function of a car navigation system, or when the capacity of the storage medium used on one board becomes full. , The other storage medium can be used.

(1-18) When the event occurs, measurement information measured before the event occurs, after the event occurs, or a combination of two or more thereof is also output.

By doing so, the measurement information measured in a certain period before and after the event occurs can be grasped at the output destination. Further, since there is a combination of two or more of these, it is preferable to use a combination such as a fixed period at the time of event occurrence and before the event occurrence, or a fixed period at the time of event occurrence and after the event occurrence.

For example, the measurement information may be the moving speed of the moving body, and the output destination may be the display unit. By doing so, the user can prove that the event was below the legal speed at the time of the event, or that the event was slowing down properly. The moving speed of the moving body can be calculated by using, for example, GPS position information. It is also possible to acquire the moving speed of the moving body by using, for example, OBD (On-board diagnostics).

(1-19) The program is characterized in that the computer functions as the device described as (1) to (1-18) described above.

It is possible to realize all or at least a part of the functions of the devices described as (1-1) to (1-18) above by a computer.

(1-a) If it is determined that the event has occurred when the image data is stored in a predetermined number or when the image data is stored in a predetermined number, the event is described. It is characterized in that the stored image data or a part or all of the stored image data is deleted.

For example, a state in which the maximum storable number of image data is determined based on the capacity of the storage medium and the number of image data stored (or is memorized) close to the maximum storable number is determined. It is preferable that a predetermined number of the image data are stored (or stored).

By doing so, the image data is deleted when the maximum number of storable cases is approached. Therefore, it is possible to prevent a situation in which the maximum number of storable cases is reached and the image data cannot be memorized when the next event occurs.

(1-b) The threshold value can be set to a different value for each measurement axis, and the threshold value of the measurement axis corresponding to the traveling direction of the moving body is higher than the threshold value of the other measurement axes. ..

By doing so, it is possible to use a threshold value according to the usage status of the device, and it is possible to prevent it from being mistakenly determined that an event has occurred when the event has not occurred.

In this regard, depending on the usage status of the device, the value measured by the acceleration sensor may increase in a predetermined direction regardless of the occurrence of the event. For example, when the front surface of the device is a touch panel, the user presses the touch panel, so that the measured value by the acceleration sensor increases on the measurement axis corresponding to the direction from the front surface to the rear surface of the device. Since this has nothing to do with the occurrence of the event, it is preferable not to determine that the event has occurred in such a case. Therefore, for example, the threshold value may be increased in the measurement axis corresponding to the direction from the front surface to the rear surface of the device. This makes it possible to determine that an event has not occurred even if a slight impact is detected.

Further, for example, when the device is installed in an automobile, the front surface of the device provided with the touch panel faces the front of the user, and the rear surface of the device faces the traveling direction of the automobile. Therefore, for example, when the moving body traveling direction is the front, the measurement axis corresponding to the moving body traveling direction is the X direction (front and back), and when the moving body traveling direction is the front, the measurement axes corresponding to the left and right of the moving body are set. When the Y direction (left and right) is set and the moving body traveling direction is the front, the measuring axis corresponding to the top and bottom of the moving body is set to the Z direction (left and right), and the threshold value for the measuring axis in the X direction (front and back) is increased. You should do it.

(1-c) When it is determined that the event has occurred, the notification unit is controlled to light up, and the notification unit is installed at a place where the lighting by the notification unit is reflected on the windshield of the moving body. It is characterized by that.

By doing so, it is possible to see the lighting or blinking reflected on the windshield, and the user can easily recognize that the event has occurred. For example, when driving a moving body at night, the notification unit may be turned on.

(1-d) When the moving body is located in the vicinity of the place where the event occurs, at least a part of the functions performed by the device controlled by the device is restricted.

By doing so, the user can concentrate on driving the moving body at the place where the event occurred last time.

In places where events have occurred in the past, it is often desirable to be careful and drive. For example, suppose there is a place where it is determined that an event has occurred because the brake was applied suddenly last time. In this case, the functions of the device to be controlled are partially restricted in the vicinity of this location. For example, as described in (6) above, the device to be controlled is a device capable of reproducing a television image, and the function executed by the device to be controlled by the device is a function that hinders the acquisition of the image data. , Should be the audio output function of the TV. By doing so, it is possible to stop the output of the TV sound that interferes with driving near the place where the sudden braking was applied before, and the user can concentrate on driving the moving body.

(2-1) A first power consumption unit that controls one or both of a control for outputting information to a user and a control for receiving an operation from the user, and a first power consumption unit. Is equipped with a second power consuming unit that performs different controls,
When a voltage is applied to the first power consumption unit and the second power consumption unit at the same time and the rated current of the external power supply is exceeded, when the power supply from the external power supply is started, the first power consumption unit is reached. It is characterized in that a first application of applying a voltage is performed, and after the application of the first 1-1, a second application of applying a voltage to a second power consumption unit is performed.

In this way, the maximum value of the total value of the required currents can be lowered by passing the current stepwise by applying the voltages in order. This makes it possible to start the device even with a low current power supply. Further, since the first power consumption unit that controls either or both of the control for outputting information to the user and the control for accepting the operation from the user is targeted for application first. The user can quickly start to refer to the information or perform an operation.

Further, for example, it is preferable to use a mobile car charger to supply power from the outside. In this way, a low current car charger can be used and the cost can be reduced. In addition, the low-current car charger cable is thin, which makes it easier for the user to handle.

(2-2) The second power consumption unit includes a portion that needs to receive power from a capacitor and perform a predetermined operation termination process when the power supply from the external power supply is cut off.
Before the second application is performed, the first and second applications for applying a voltage to the capacitor are performed.

By doing so, power is supplied to the capacitor before the second power consuming unit is activated, and the second power consuming unit stores the electric charge for performing a predetermined operation termination process in the capacitor. be able to. Therefore, it is possible to reliably execute the required predetermined operation termination process.

The operation end process may be, for example, a process of storing the data processed by the second power consumption unit in the storage medium. This makes it possible to prevent the file being processed from being damaged.

(2-3) The device includes a secondary battery for continuing driving when the device is removed from the external power source, and a voltage is applied to the secondary battery after the second application. It is characterized in that the application of 3 is performed.

Immediately after the application to the second power consumption unit is started, a large amount of current is still consumed. Therefore, if a current is passed through the secondary battery at this stage, the rated current of the external power supply will be exceeded.

Therefore, by preventing the third application from being applied immediately in this way, it is characterized in that the rated current of the external power supply is prevented from being exceeded.

For example, when the application is performed after waiting for the voltage of the capacitor to rise, it is possible to start the application at an appropriate timing when the voltage of the capacitor rises. The power storage device may be a supercapacitor.

(2-4) The time required for the device to perform a predetermined function by the first power consuming unit to which the voltage is applied is determined by the second power consuming unit to which the voltage is applied. It takes longer than the time it takes to perform the function of.

When providing various functions to the user, the power consumption unit that takes time to perform the function is prior to the power consumption unit that does not take a relatively long time to perform the function. A voltage should be applied. Therefore, in this way, the voltage is applied to the first power consuming unit, which takes a relatively long time to exert a predetermined function, before the second power consuming unit. As a result, the user can use the function exhibited by the first power consumption unit at an early stage. As described in the above column (2-1), the user can be used by the first power consumption unit. Since either or both of the control for outputting information and the control for accepting operations from the user are performed, the first power consumption unit is targeted for application first. The user can quickly start referencing information and performing operations.

(2-5) The device exerts a map display function by the first power consumption unit, and the device exerts a drive recorder function by the second power consumption unit, and outputs in relation to the drive recorder function. It is characterized by displaying the information to be displayed on a map.

Further, since the application is applied to the first power consumption unit first, the map display function can be quickly activated. It is considered that the user of the mobile body often starts driving after checking the map. Also, if the drive has not started, the need for the drive recorder to function is less than during operation. Therefore, for example, instead of activating the drive recorder function first, it is preferable to activate the drive recorder function after activating the map display function. This makes it possible to set the startup order suitable for the usage situation of the user.

(2-6) It is characterized in that control is performed to provide operation guidance to a place specified by the position information acquired in connection with the drive recorder function.

By doing so, the user receives the operation guidance to the place related to the drive recorder function. For example, it is possible to easily revisit a place where an accident occurred in the past, a place where an event occurs frequently, or a place where a user manually recorded a video.

(2-7) The feature is that control is performed to continue the operation guidance even when the map is not displayed.

For example, even when the map is not displayed, that is, even when the real-time image or TV image taken by the camera is displayed, it is preferable to continue the operation guidance by voice output.

(2-8) If the voltage of the capacitor exceeds the first predetermined voltage, the second application is controlled to be started, and the voltage of the capacitor exceeds the second predetermined voltage. If this is the case, the second power consuming unit is controlled so as to be able to exert a predetermined function.

Even if the activation process of the second power consuming unit is completed, it is considered that the storage of electricity in the capacitor is insufficient if the second power consuming unit immediately executes a predetermined function. Therefore, by doing so, the start-up process is started when the voltage required for start-up is reached, and the execution of the predetermined function is started only after the voltage becomes such that the predetermined function can be executed. As a result, it is possible to prevent the predetermined function from being executed even though the storage in the capacitor is insufficient. The predetermined function may be, for example, a drive recorder function.

(2-9) The second power consuming unit is controlled so that the third application is performed when the predetermined function can be executed.

Immediately after the application to the second power consumption unit is started, the storage in the capacitor is insufficient and a large amount of current is consumed. Therefore, if a current is passed through the secondary battery, which is another device, at this stage, the maximum value of the total current value exceeds the assumption.

Therefore, by doing so, it becomes possible to pass a current through the secondary battery, which is another device, in a state in which a predetermined function can be executed, that is, after the storage in the capacitor is sufficiently performed. Therefore, it is possible to prevent the maximum value of the total current value from exceeding the rated current of the power supply source.

(2-10) The first power consuming unit has the first power consumption unit in any or all of the periods from the start of power supply from the external power source to the start of the third application. The power consuming unit of No. 2 is characterized in that it controls to output that the predetermined function is not in a state where it can be exhibited.

As described in the above-mentioned column (2-1), it is preferable to first activate the first power consumption unit for outputting information to the user. Therefore, first, a current is passed through the first power consumption unit. Then, by doing so, it becomes possible for the first power consumption unit to output that the predetermined function by the second power consumption unit cannot be used yet. For example, it is advisable to output a display such as "Currently, the drive recorder function cannot be used" on the display unit. As a result, the user can recognize that the power supply is properly started and that the predetermined function by the power consumption unit of 2 is in the process of being activated.

(2-11) When the supply of power from the outside is cut off, the control is performed so as to stop a predetermined function operating on the second control unit.

As a result, the power consumption can be reduced when the supply of power from the outside is cut off. For example, when it is removed from a moving car charger, the function as a drive recorder becomes unnecessary. Therefore, by doing so, it is possible to stop unnecessary functions and reduce the consumption of the secondary battery.

(2-12) Both the function of operating on the first power consuming unit and the function of operating on the second power consuming unit when the device receives power from the predetermined external power source. It is characterized by stopping the function.

By doing so, the power consumption can be reduced, and the secondary battery can be charged efficiently.

For example, when power is being received from a device other than a mobile device, it is considered that the device is not used in the mobile device and is connected to a terminal or outlet that conforms to the USB (Universal Serial Bus) standard of a personal computer. .. In this case, in addition to the function as a drive recorder, the map display function is also unnecessary. Therefore, by doing so, it is possible to stop unnecessary functions and reduce the consumption of the secondary battery.

(2-13) The program is characterized in that the computer functions as the device described as (2-1) to (2-13) described above.

It is possible to realize all or at least a part of the functions of the devices described as (2-1) to (2-13) above by a computer.

(2-a) A device characterized in that the secondary battery is controlled to apply a voltage to the first power consuming unit when the power supply from the external power source is cut off.
When it is cut off, for example, when it is removed from the car charger of a moving body, the function as a drive recorder becomes unnecessary. Therefore, a voltage is applied from the secondary battery to the first power consumption unit that realizes the map display function, not to the second power consumption unit that realizes the function of the drive recorder. By doing so, the map display function can be used immediately even if the power supply from the outside is cut off. In addition, it is preferable to make the device portable so that the user can carry it around and use it.

According to the present invention, it is possible to use functions implemented in separate devices in cooperation with each other.

Further, the touch panel 110 displays the image data input from the first control unit 100 on the screen. Further, the touch panel 110 displays the image data input from the 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 blinks under the control of the first control unit 100.

The button 140 is a physical button 140 provided in the housing of the integrated device 1000 and accepts a user operation.

Here, when the integrated device 1000 is installed and used in an automobile as described above, each of the touch panel 110, the speaker 120, and the notification LED 130 outputs the output of the touch panel 110, the speaker 120, and the notification LED 130 by the user. It is placed in a detectable position. Further, the touch panel 110 and the button 140 are arranged at positions that can be operated by the user.

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

The GPS sensor 160 positions the current position of the integrated device 1000 using GPS, and outputs the measured position information to the first control unit 100. Here, the position information is realized by, for example, coordinate information conforming to the GPS standard.

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

The first storage unit 180 is a portion into which a removable storage medium is inserted by the user. For example, an MP3 (MPEG-1 Audio Layer-3) format music file and a storage medium in which a television image written by the first control unit 100 is stored are inserted into the first storage unit 180. Then, under the control of the first control unit 100, these music files and television images are read from the storage medium and output from the speaker 120 and the touch panel 110.

Information for car navigation is stored in the main storage unit 190. Specifically, map information, information on a certain target, information for specifying a road type, facility information, address information, and the like are stored. Further, the main storage unit 190 stores software for realizing control by the first control unit 100.

Further, the software of the main storage unit 190 can be updated by using the latest data of the software updated after the shipment of the integrated device 1000, the latest data of the target object, and the like. For example, a storage medium in which the latest data is stored is inserted into the first storage unit 180, and the first storage unit 180 reads additional data from the storage medium to update the software of 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 and used in the automobile as described above, the current position determined by the GPS sensor 160 represents the current position of the automobile, and the acceleration measured by the acceleration sensor 170 is the acceleration of the automobile. It will represent the acceleration. Then, the first control unit 100 creates a map for operation guidance including the current position of the automobile by comparing the current position measured by the GPS sensor 160 with the map information stored in the storage unit. , The map for this operation guidance is displayed on the touch panel 110. In addition, 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 controls the camera 210, the microphone 220, and the second storage unit 230, among the above-mentioned units.

Then, the second control unit 200 inputs the video signal captured by the camera 210 and the acoustic signal collected by the microphone 220, converts the input video signal and the acoustic signal into image data of a predetermined format, and stores the storage unit. Store in. In the following description, the image data converted by the second control unit 200 is referred to as "real-time video".

Here, the object to be imaged as a drive recorder is, for example, the scenery in the traveling direction and the surrounding sound imaged from the inside of the automobile through the windshield. Then, the second control unit 200 realizes the function as a drive recorder by storing the object to be imaged as 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. Note that in FIG. 1, the wiring for the power supply unit 310 to supply power to each functional block is not shown.

The USB terminal 320 is a terminal compliant with the USB standard. The USB terminal 320 is connected to an external device via a cable compliant with the USB standard. Then, power is supplied from the external device via a cable. It is also possible for the first control unit 100 and the external device to communicate with each other via a cable.

Here, when the integrated device 1000 is installed and used in an automobile, the cable connected to the car charger of the automobile is connected to the USB terminal 320. Then, the integrated device 1000 is supplied with power from a car charger of an automobile.

The functional block of this embodiment has been described above.

The first control unit 100 and the second control unit 200 described above are realized by arithmetic units such as a CPU (Central Processing Unit), RAM (Random Access Memory), ROM (read only memory), and the like, respectively. To. Then, the CPU reads the software stored in the ROM or the main storage unit 190 and performs arithmetic processing while expanding the software in the RAM, so that the control by the first control unit 100 and the second control unit 200 is realized.
<Processing of this embodiment>
Next, each of the processes performed by the present embodiment will be described in detail with reference to the drawings.
<Real-time video recording>
First, the recording of real-time video 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: continuous recording, manual recording, and event recording.

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

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

Next, continuous recording will be described. The real-time video is stored in the second storage unit 230 from the start of the acquisition of the real-time video to the end of the acquisition of the real-time video. That is, while the engine of the automobile is operating, the recorded real-time video is always recorded. 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. The unit of the predetermined length is arbitrary, but for example, one file may be set in units of 30 seconds. In the following description, this file is called a "video file".

As shown in "From startup until the capacity of the second storage unit 230 is full" in the upper left of FIG. 2, the capacity of the second storage unit 230 is until the capacity allocated for continuous recording is full. The video file will continue to be saved. The capacity allocated for continuous recording is arbitrary, but it is preferable that the capacity is such that a video file corresponding to a length of 20 minutes can be recorded.

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

Next, manual recording will be described. When the user detects that the button 140 is pressed, manual recording is executed. Then, the video file including the time when the button 140 is detected and the video file immediately before the video file are protected. That is, two video files are protected by pressing once. Protected here means that the protected video file is excluded from the deletion of the oldest video file by continuous recording.

Then, the two protected video files, the date and time when the two video files were captured, and the position information for specifying the position where the two video files were captured are linked and stored in the second storage unit 230 as a set. In addition, it is necessary to add an identification code to the set to identify this set, but the date and time when the two video files were captured is used not only for confirming the date and time but also as an identification code. It is good to do so. Further, as the position information, the coordinate information determined by the GPS sensor 160 may be requested from the first control unit 100, and the coordinate information transmitted from the first control unit 100 may be used in response to the request.

Further, the second control unit 200 notifies the first control unit 100 that the manual recording has occurred. Specifically, the fact that the manual recording has occurred, the date and time when the manual recording was performed, and the position information that specifies the position where the manual recording was performed are linked and transmitted to the first control unit 100 as a set. Then, the first control unit 100 stores the received information in this set 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, but for example, it may be the capacity of a maximum of 10 cases, that is, the capacity of 20 video files. The oldest case is when the user presses the button 140 and a new manual recording is executed, or when the event recording described later is newly executed while protecting 20 video files. Remove two video files from protection and delete them. This makes it possible to protect new video files.

Next, event recording will be described. When the first control unit 100 determines that an event has occurred, event recording is executed. The criteria for determining that an event has occurred by the first control unit 100 will be described next to the description of this event recording.

Then, the video file including the time when the event occurs and the video file immediately before the video file are protected. That is, two video files are protected according to the occurrence of one event.

Then, the two protected video files, the date and time when the two video files were captured, and the position information for specifying the position where the two video files were captured are linked and stored in the second storage unit 230 as a set. Further, as in the case of manual recording, the date and time when the two video files were captured may be used as the identification code. Further, as for the position information, it is preferable to use the coordinate information transmitted from the first control unit 100 as in the manual recording. Further, as in the case of manual recording, it is preferable to use the coordinate information transmitted from the first control unit 100 as the position information.

As with the manual recording, 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 10 cases including the number of manual recordings, that is, a video file The capacity should be 20 pieces. Similar to manual recording, when recording is performed while 20 video files are protected, it is advisable to remove the two oldest video files from the protection target and delete them.

The video file recorded in this way can be played back according to the user's operation. For example, as shown in FIG. 3, the date and time when the protected video file was captured is displayed as a list on the touch panel 110 as an identifier. Then, the touch panel 110 accepts the user's selection, and the video file corresponding to the selection is played back on the touch panel 110. In addition, in the case of manual recording, an icon like i1 in FIG. 3 is attached so that the user can distinguish between manual recording and event recording, and in the case of event recording, i2 in FIG. 3 having a shape different from i1. I try to attach an icon like this.

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

In order to determine the occurrence of this event, the acceleration measured by the acceleration sensor 170, which is measurement information that changes with the movement of the automobile, and the threshold value are used. Then, it is determined that an event has occurred when the measured acceleration exceeds the threshold value. By doing so, the car collided with another moving object or an installation object, and there was a sudden stop, a sudden call, or a sharp turn based on the driving of the user who operates the car, that is, an event occurred. Can be judged.

Further, the threshold value is not limited to one, but a plurality of threshold values are provided step by step. Then, by determining which of the threshold values provided by the acceleration sensor 170 is exceeded in stages, it is not only that the automobile has collided with another moving object or an installed object, but also the impact at the time of the collision. You can also judge how much was.

For example, the threshold value of the most sensitive stage is set to 0.5 G, and the insensitivity is gradually set from there. That is, the threshold of the second insensitive stage is 0.8G, the threshold of the intermediate stage is 1.1G, the threshold of the second insensitive stage is 1.4G, the threshold of the most insensitive stage is 1.7G, and so on. For example, 5 steps are set step by step.

If the measured value of the acceleration sensor 170 is less than 0.5 G, for example, it is not determined that the event has occurred. Further, if the measured value of the acceleration sensor 170 is, for example, 0.9 G, it is determined that the level 2 event has occurred because the threshold value of the second insensitive stage is exceeded. Further, for example, if the measured value of the acceleration sensor 170 is, for example, 1.9 G, it is determined that the level 5 event has occurred because the threshold value of the most insensitive stage is exceeded. As described above, the higher the measured value of the acceleration sensor 170, 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 links the position information for specifying the position where the event occurred, the level of the event that occurred, and the date and time when the event occurred as a set. Stored in the main storage unit 190. Further, the date and time when the event occurred may be used as an identification code for identifying each event in the same manner as that performed by the second control unit 200 during manual recording or event recording. ..

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

For example, if you are using the navigation function, a message will pop up on the map. 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. Then, i3 shown in FIG. 4 is a message popped up to indicate the occurrence of an event. The level of the event that occurred is displayed in "*****" of this message. For example, it may be displayed as "an event of level 3 has occurred". In addition, such a message is urgent and is very important to convey to the user. Therefore, when using a function other than the navigation function, for example, even during playback of the television image, it is preferable to pop up a message on the television image.

Further, in the area of i4 shown in FIG. 4, an area for displaying various information used for operation guidance is provided. In the example shown in FIG. 4, from above, for example, the current time acquired from a GPS satellite, the reception strength and direction of a GPS signal, a value indicating a map scale, and a shortcut button 140 are arranged in this area.

Here, the shortcut button 140 is a button 140 that switches the screen each time it is pressed. Since screen switching, that is, screen transition will be described later, detailed description thereof will be omitted here.

Further, i5 shown in FIG. 4 displays the current traveling speed of the automobile in which the integrated device 1000 is installed.

Further, in i6 shown in FIG. 4, the address, road name, latitude / longitude of the place where the automobile in which the integrated device 1000 is installed is currently traveling are displayed. Further, it is also preferable that the menu screen is displayed when i6 shown in FIG. 4 is pressed.

Further, when it is determined that an event has occurred as described above, event recording is performed.
<Display method>
Next, the display method in this embodiment will be described. In the present embodiment, the position where the event was recorded because the event occurred and the position where the manual recording was performed according to the user's operation are displayed as, for example, an icon on the map for operation guidance displayed by the car navigation system function. .. In the following description, this icon is referred to as an "event icon".

Then, when the user presses the event icon on the touch panel 110, the corresponding image data is reproduced. Here, the corresponding image data is captured by the function of the drive recorder. That is, in this embodiment, the car navigation function and the drive recorder function are linked.

The event icon may be a single color, but may be different colors depending on the level of the event, for example. By doing so, the user who refers to the event icon not only knows where the event was, but also knows "how many levels" the event was.

Further, it is preferable to be able to distinguish between the position where the event was recorded because the event occurred and the position where the manual recording was performed according to the user's operation. Therefore, the color of the event icon representing the position where the manual recording was performed is different from the color of the event icon representing the position where the event recording was performed. Further, it is preferable to assign a color according to, for example, a signal sign so that the user can intuitively recognize it.

For example, the event icon of a level 1 event, which is an event based on a slight impact, is green. In addition, the event icon of the level 1 event, which is an event based on the impact of the intermediate level, is yellow. Furthermore, the event icon of the level 5 event, which is an event based on a large impact, is red. Also, the event icon corresponding to manual recording is indigo.

The following [Table 1] shows an example of this color assignment. In the following description, the description will be based on this allocation.

Then, the event icons to which the colors are assigned in this way are superimposed on the map for operation guidance as shown in FIG. 5 and displayed on the touch panel 110.

Further, as described above with reference to FIG. 2, in the present embodiment, the upper limit of the number of recordable cases for each of the manual recording and the event recording is determined. For example, the maximum number of video files for manual recording and event recording is 20, that is, 10 in total. Then, when a new recording is made, the oldest one is deleted even if the user has not yet watched it. Therefore, it is preferable to let the user know which old one is about to be deleted. And it is preferable to encourage them to watch before deleting.

It also allows the user to know which event icon corresponds to the event recording that just happened, which event icon corresponds to, for example, the manual recording that was done three times ago, and so on. It is preferable to keep it.

Therefore, instead of simply displaying each event icon in a color-coded manner, for example, the event icon is a circled number including a number in chronological order. This allows the user to know which event icon is new, old, and old.

In order to display these event icons, the first control unit 100 uses the map information stored in the main storage unit 190. Further, when the manual recording occurs, the information received from the second control unit 200 and stored in the main storage unit 190, "the fact that the manual recording has occurred, the date and time when the manual recording was performed, and the manual recording are performed. A set of position information that identifies the damaged position is used. Further, the information stored in the main memory 190 when the event occurred, "the position information for specifying the position where the event occurred, the level of the event that occurred, and the date and time when the event occurred were linked to form a set. "Things" are used.

A specific example when the event icon is displayed with these contents is shown in FIG.

Referring to FIG. 5, first, a map for operation guidance is displayed on the touch panel 110. Then, it can be seen that i8 on the map is indigo and includes an event indicating the position where the manual recording was performed. Further, since the number is 1, it can be seen that it represents the position where the manual recording was most recently performed.

Further, it can be seen that i9 on the map is yellow and is an event inclusion indicating the position where the level 3 event recording was performed. Further, since the number is 2, it can be seen that it represents the position of the event recording performed immediately before the manual event performed at i8 on the map.

Further, it can be seen that i10 on the map is red and is an event inclusion indicating the position where the level 5 event recording was performed. Further, since the number is 3, it can be seen that it represents the position of the event recording performed immediately before the event recording corresponding to i9 on the map.

Further, it can be seen that i11 on the map is green and is an event inclusion indicating the position where the level 1 event recording was performed. Further, since the number is 4, it can be seen that it represents the position of the event recording performed immediately before the event recording corresponding to i10 on the map.

Further, i12 on the map is an event icon indicating the current position and traveling direction of the automobile in which the integrated device 1000 is installed.

The user who referred to the information displayed in FIG. 5 said, for example, "Because we are approaching the place where the level 5 event was generated before, let's avoid driving so that the event occurs this time." It is possible to make a judgment such as "If you proceed as it is, do not go through the place where the manual recording was done before." That is, it is possible to present useful information to the user.

When the user presses the event icon, the video file corresponding to the event icon is played.

Specifically, when any of the event icons is pressed, a list of event icons including the event icons is displayed on, for example, the right half of the touch panel 110 as shown in i13 of FIG. Therefore, as shown in i14 of FIG. 6, the map is displayed in the left half, for example.

Then, the first control unit 100 determines which event icon in the event list is pressed by the user based on where the touch panel 110 is pressed. Then, the date and time when the event recording of the event corresponding to the pressed event icon is performed, or the date and time when the manual recording corresponding to the pressed event icon is performed is read from the main storage unit 190. Then, the read date and time is transmitted 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 out. Here, since two video files are set for each manual recording and each event recording, the two video files in this set are read out. Then, the second control unit 200 decodes these two read video files into image data. Then, the image data is transmitted to the first control unit 100.

The first control unit 100 reproduces the received image data by outputting it to the touch panel 110. By referring to the reproduced image data, the user can confirm the state when manual recording or event recording is performed.

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

Here, the reason for deleting the video file is that the capacity of the second storage unit 230 is taken into consideration, and if possible, information on manual recording or event recording earlier than 10 is displayed on the map. Is preferable.

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

Therefore, this information is kept stored in the main storage unit 190 without being deleted. Then, using this information, the occurrence position for manual recording and event recording and the icon indicating the level of event recording are displayed on the map. In the following description, such an icon is referred to as a "history icon" to distinguish it from an event icon.

The amount of data required to display the history icon is small as described above. However, if the history icons are displayed even for past manual recordings and event recordings, too many icons will be displayed on the screen, which hinders operation guidance.

Therefore, an upper limit is set for the number of icons to be displayed. For example, 10 event icons and 490 history icons, for a total of 500 events.

It is also necessary to distinguish between history icons and event icons. Therefore, for example, the shape of the history icon and the shape and size of the event icon are made different. For example, the shapes are different, such as a round shape and a rectangular shape. Alternatively, both have the same round shape, but the event icon is larger and the history icon is smaller, so that the sizes are different. Further, in any case, the color and size of each history icon are set so that they can be discriminated. In the following description, the history icon will be displayed in a diamond shape.

Specifically, the information used to display the history icon is "manual recording" which is information received from the second control unit 200 when manual recording occurs and stored in the main storage unit 190. Is used as a set by associating the date and time when the manual recording was performed and the position information that specifies the position where the manual recording was performed. Further, the information stored in the main memory 190 when the event occurred, "the position information for specifying the position where the event occurred, the level of the event that occurred, and the date and time when the event occurred were linked to form a set. "Things" are used.

A specific example of displaying the event icon with these contents is shown in FIG. The specific example of FIG. 7 is deleted due to the old video file corresponding to the event icon shown in the specific example of FIG. 5, and is replaced with the history icon.

Referring to FIG. 7, first, a map for operation guidance is displayed on the touch panel 110. The i15 on the map is indigo and is a history icon indicating the position where the manual recording was performed.

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

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

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

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

In this way, by displaying not only the event icon but also the history icon, the user can grasp the place where the event frequently occurs.
<Screen transition>
Next, how the screen transitions according to the situation of the automobile and the operation of the user will be described with reference to the transition diagrams of FIGS. 8 to 10.

First, refer to FIG. When the first control unit 100 is activated, the main menu is displayed as shown in the screen S1. On the main menu screen, you can select various functions of navigation, TV, music, pictures, and drive recorder. Among these, the functions of the navigation and the drive recorder, which are the features of the present embodiment, will be described.

When the [Navigation] button 140 is selected on the screen S1, the navigation function is activated and the screen S2 is displayed.

On the screen S2, as described with reference to FIGS. 5 and 7, an event icon and a history icon are displayed on the map for operation guidance, and the operation guidance is executed with voice output. The content of such display is the content described in the above-mentioned <Display method> column. Further, the method of determining the occurrence of an event by the first control unit 100, the operation at the time of event occurrence, and the like are the contents described in the above-mentioned <Event occurrence> column. Here, it is assumed that the user presses the [Shortcut] button 140. Here, it is assumed that the [shortcut] button 140 is associated with the “camera 210 image”. In this case, the screen transitions to the screen S3, and a real-time image which is an image currently captured by the camera 210 is displayed on the screen. When the user presses the [End] button 140 in this state, the screen S2 is displayed and the operation guidance is executed again.

When any of the [icon] buttons 140 is pressed in the state of the screen S2, the process for playing the video file corresponding to the pressed event icon or history icon is started. Specifically, the screen S4 is displayed, a message indicating that the continuous recording is suspended is output, and the user can select either [Yes] or [No] button 140.

Here, the reason for suspending the continuous recording is to prevent a situation in which the image data being played is overwritten when it is determined that a new event has occurred during the image data playback. This is because it becomes possible.

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

Here, when the user presses the [No] button 140, the screen S2 is displayed and the operation guidance is continued.

On the other hand, when the user presses the [Yes] button 140, 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, this time, the user wants to play the video file corresponding to the icon selected on the screen S2 instead of playing the video file corresponding to the icon selected from the event list on the screen S5.

Therefore, the entire event list is treated as the [event item] button 140, and when the [event item] button 140 is pressed for the first time, the map is moved to the coordinate value with the icon selected on the screen S2. Then, when the [event item] button 140 is pressed for the second time, the screen S6 is displayed and the moving image playback is started.

On the screen S6, the message "Play the video" is displayed while the process for generating the moving image is being performed. Then, when the message "Play the video" is displayed for a length equal to or longer than the predetermined time required for processing for generating the moving image, it is determined that the time-out has occurred and the screen S7 is displayed. Then, on the screen S7, the video file corresponding to the icon selected on the screen S2 is played.

Then, when the user presses the [Back] button 140 during or after shooting, the screen S5 is displayed. Then, when the press of the [Back] button 140 is accepted on the screen S5, the screen transitions to the screen S2 and the operation guidance is continued. In addition, continuous recording is resumed without requiring user operation.

Next, when any [icon] button 140 is pressed in the state of the screen S2 as described above, the user does not play the video file corresponding to the pressed icon, but the user uses the icon from the event list. Is selected, and the operation when playing the video file corresponding to the icon selected from this event list will be described.

When the pressing of the [MENU] button 140 profitable at the bottom of the screen is accepted 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 pressing of the [Register / Edit] button 140 is accepted in the state of the screen S8, the screen transitions to the screen S9 which is the registration / edit menu screen.

Then, when the pressing of the [event] button 140 is accepted in the state of the screen S9, the screen transitions to the screen S10 of FIG.

Similar to the screen S4, the screen S10 outputs a message to the effect that the continuous recording will be temporarily suspended, and accepts the user's selection of either [Yes] or [No] button 140. The reason why the continuous recording is temporarily suspended is as described in the explanation of the screen S4.

Here, when the user presses the [No] button 140, the screen transitions to the screen S9 of FIG. 8, which is the registration / editing menu screen.

On the other hand, when the user presses the [Yes] button 140, 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 case of the screen S5, since the user has not selected the icon on the screen S2, the user accepts the selection of the user's icon from the event list on the screen S5.

Then, the playback of the video file corresponding to the icon selected by the user is started. Subsequent processing on the screens S6 and S7 is the same as the processing when the screen S5 transitions to the screen S6, and thus detailed description thereof will be omitted. In FIG. 9, the screen S5 is returned when the return button 140 is pressed on the screen S7, but the screen S11 may be returned instead of the screen S7.

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

First, when the [Drive Recorder] button 140 is pressed on the screen S1, the screen transitions to the screen S12 or the screen S13 shown in FIG. Here, it is a condition of which screen to transition to, but when the integrated device 1000 is not installed in the automobile and the integrated device 1000 is receiving power from the secondary battery included in the power supply unit 310. Transitions to the screen S12. On the other hand, when the integrated device 1000 is installed in the automobile and the integrated device 1000 receives power from the automobile, the screen S13 is displayed.

First, a case where the former integrated device 1000 is not installed in the automobile and the integrated device 1000 receives power from the secondary battery included in the power supply unit 310 will be described for transitioning to the screen S12. In this case, since the battery capacity of the secondary battery has an upper limit, it is necessary to suppress the power consumption. Further, 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 the present embodiment, the function of the drive recorder is not operated when the power is supplied from the secondary battery. Then, in order to inform the user to that effect, when the screen S12 is displayed, a message such as "The recording / playback function of the drive recorder does not operate while the unit is being driven by the built-in battery" is displayed. Then, when a predetermined time that the user can recognize this message elapses, it is determined that the time-out has occurred, and the screen S1 is displayed.

Next, a case where the integrated device 1000 is installed in the automobile and the integrated device 1000 receives power from the automobile causes a transition to the screen S13 will be described.

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

Then, on the screen S14, the [Application end] button 140 is displayed. Then, when the user accepts the press of the [Application Exit] button 140, the operation of the application that realizes the drive recorder function is terminated, and the screen S1 is displayed. On the other hand, when the screen is pressed on the screen S14, the screen returns to the screen S13 again, and the real-time image is reproduced in full screen display. In addition, on the screen S14, for example, a button 140 for changing the setting is displayed, and when the button 140 for changing the setting is pressed, the screen further transitions to, for example, a screen for making various settings related to the drive recorder function. It is good to do.

Further, when the user's operation is accepted while the screens S13 and S14 are displayed, the manual recording described with reference to the middle part of FIG. 2 is started with this as an opportunity. That is, the real-time video reproduced on the screens S13 and S14 is used as a preview image for manual recording.
<Battery control>
Next, the control of the battery in this embodiment will be described.

The power supply unit 310 of the integrated device 1000 of the present embodiment receives power 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 of the cigar plug cords 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. It is assumed that the cigar plug cord and the converter have a rated voltage of 5V and a rated current of 2A, for example.

After that, when the engine of the automobile is started, 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, a detailed configuration of the power supply unit 310 will be described with reference to FIG. Referring to FIG. 11, the power supply unit 310 includes a power supply control unit 311 and a lithium ion battery 312 and a supercapacitor 313 (registered trademark). Further, 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 not shown in FIG.

The supercapacitor 313 corresponds to the "storage device" of the present invention. Further, the lithium ion battery 312 corresponds to the "secondary battery" of the present invention. Further, the power source supplied from the cigarette lighter socket of the automobile corresponds to the "external power source" of the present invention.

Here, the power supply control unit 311 has a function of controlling which device the voltage is applied to. The power control unit 311 is realized by, for example, a power management IC. Further, the first control unit 100 may perform a part or all of the control of the power supply control unit 311. In FIG. 11, a signal line for the first control unit 100 to transmit and receive a signal for controlling the power supply control unit 311 is shown by a broken line. On the other hand, the line for applying the voltage is shown in FIG. 11 as a solid line.

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

On the other hand, when the integrated device 1000 is not supplied with power from the external device, the first control unit 100 is driven by the power supplied by the lithium ion battery 312. Further, as described above in the explanation column of <Screen Transition>, when the integrated device 1000 is not supplied with power from an external device and is driven by the power supplied by the lithium ion battery 312, the drive recorder Stop the function of. Since the purpose of this is to reduce power consumption, not only the software operating in the second control unit 200 is shuttered down, but also the application of the voltage to the second control unit 200 itself is stopped. To do.

The supercapacitor 313 is a power storage device, and is stored when the integrated device 1000 receives power from an external device.

In this respect, in the present 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. Prevent data corruption by performing the shutdown process of.

However, when the integrated device 1000 is removed from the automobile as described above, the application of the voltage to the second control unit 200 is stopped. Therefore, the second control unit 200 performs this shutdown process using the electric charge stored in the supercapacitor 313. Therefore, the supercapacitor 313 has a capacity that can guarantee that the shutdown process 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 been converted into a video file.

The first control unit 100 also controls the power supply. For example, the first control unit 100 includes a touch panel 110, a speaker 120, a notification LED 130, a button 140, a TV tuner 150, a GPS sensor 160, an acceleration sensor 170, and a first memory among the units shown in FIG. The power supply of the unit 180 and the main storage unit 190 is controlled. Further, the first control unit 100 may perform a part or all of the control of the power supply control unit 311.

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

Next, the basic idea of battery control in this embodiment will be described. In the present 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 them. Do it step by step. This is to start the first control unit 100 and the second control unit 200, and to 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, for example, 2A. In this regard, it is conceivable to use a cigar plug cord having a rated current exceeding 2A. However, as the rated current increases, it becomes necessary to make the cigar plug cord thicker. This is because the conductor such as the electric wire forming the cord also has a small resistance, and the heat generation may melt the insulating coating. Therefore, it is necessary to make the cord thicker as the current is increased.

However, if the cord is made thick, it becomes difficult to handle the cord, which is very inconvenient for a user who uses the integrated device 1000 in a limited space such as in an automobile. There is also a problem that the manufacturing cost increases when a thick cord is used.

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 of the operation. Thereby, in this embodiment, the maximum value of the current at the time of starting the integrated device 1000 is suppressed.

Next, the power supply control process of the present embodiment will be described in detail with reference to the flowchart of FIG. 12 and the flowchart of FIG.

First, when the integrated device 1000 is in the shutdown state, the engine of the automobile is started in the state of being connected to the car charger. Along with this, the supply of power to the integrated device 1000 is started (Yes in step A1).

Then, the power supply control unit 311 starts applying a voltage to the first control unit 100. As a result, the first control unit 100 starts the activation process (step A2). 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. What is displayed at this time is the screen S1 shown in FIG. Then, the navigation function is executed in response to the pressing of the [Navigation] button 140 (step A3). Further, even if the [Drive Recorder] button 140 is pressed, the drive recorder function has not yet been executed. Therefore, as shown in screen S14 shown in FIG. 14, a message such as "The drive recorder is starting up. Please wait." Is displayed on the screen. Then, when a predetermined time that the user can recognize this message elapses, it is determined that the time-out has occurred, and the screen S1 is displayed. In this way, by first activating the first control unit 100 and displaying it on the touch panel 110, it is possible to convey to the user that the activation process is being performed.

Further, the power supply control unit 311 starts applying a voltage to the supercapacitor 313. Along with this, the supercapacitor 313 starts to store electricity, and the voltage of the supercapacitor 313 rises (step A4).

Next, it is determined whether or not the current voltage of the supercapacitor 313 is larger than the predetermined first voltage (step A5). Then, when the voltage of the current supercapacitor 313 becomes larger than the predetermined first voltage (Yes in step A5), the power supply control unit 311 starts applying the voltage to the second control unit 200. As a result, the second control unit 200 starts the activation process. This activation process also includes a process for activating the camera 210 and the microphone 220.

However, if the drive recorder function is executed, the maximum value of the current may exceed the rated current of the cigar plug cord. Therefore, although the second control unit 200 performs the activation process, the drive recorder function is not yet executed. Therefore, even if the [Drive Recorder] button 140 is pressed at this point, a message like the screen S14 shown in FIG. 14 is displayed as in step A3, and the drive recorder function is not executed.

Next, it is determined whether or not the current voltage of the supercapacitor 313 is larger than the predetermined second voltage (step A7). Here, the predetermined second voltage is a value larger than the predetermined first voltage.

Then, when the current voltage of the supercapacitor 313 becomes larger than the predetermined second voltage (Yes in step A7), the supercapacitor 313 is sufficiently charged, and a large amount of current is stored in the supercapacitor 313. Is no longer needed. Therefore, when the result is Yes in step A7, the process proceeds to step A8, and the second control unit 200 executes the drive recorder function (step A8). Further, the power supply control unit 311 starts applying a voltage to the lithium ion battery 312. As a result, charging of the lithium ion battery 312 is started (step A9).

As described above, in the present embodiment, the timing of applying the voltage to each part included in the integrated device 1000 is controlled. As a result, it is possible to suppress the maximum value of the current when the integrated device 1000 is started, and it is not necessary to make the cigar plug cord thicker than necessary.

This point will be described using specific values. For example, it is assumed that 1.3A is used in connection with the application of the voltage to the first control unit 100 in step A2. Further, it is assumed that with the application of the voltage to the supercapacitor 313 in step A4, for example, 0.5 A is used until at least Yes in step A5. Further, it is assumed that 0.2 to 0.3 A is used as the voltage is applied to the second control unit 200 in step A6. Further, it is assumed that 0.35A is used as the voltage is applied to the lithium ion battery 312 in step A9.

When these currents are totaled, a total of 2.55 to 2.36 A is required, which exceeds the rated current of 2 A of the cigar plug cord described above. However, in the present embodiment, by controlling the timing of applying the voltage to each part included in the integrated device 1000, it is possible to start the integrated device 1000 without exceeding the rated current of 2A.

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

The integrated device 1000 that executes the navigation function and the drive recorder function continues to monitor whether or not the power supply from the car charger is interrupted due to the stoppage of the automobile engine. Further, it continues to monitor whether or not the integrated device 1000 is removed from the car charger by removing the cigar plug cord from the USB terminal 320 or by removing the cigar plug cord from the car charger (in step A10). No and No in step A12).

Then, when the power supply from the car charger is interrupted due to the stop of the automobile engine (Yes in step A10), the first control unit 100 and the second control unit 200 are shut down. At this time, the shutdown process of the first control unit 100 is performed by the power supply by the lithium ion battery 312, and the shutdown process of the second control unit 200 is performed by the power supply by the supercapacitor 313. Then, the process returns to step A1 and waits until the power is supplied again.

On the other hand, when the integrated device 1000 is removed from the car charger by removing the cigar plug cord from the USB terminal 320 or by removing the cigar plug cord from the car charger (Yes in step A12), the second The control unit 200 of the above starts the shutdown process by supplying power 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 navigation function can be continued to be used. That is, the integrated device 1000 can be used as a portable navigation system. The first control unit 100 continues to operate by supplying power from the lithium ion battery 312. In this way, since only one of the two control units can be shut down, the other control unit does not need to perform a shutdown process and restart, and can continue to operate as it is.

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 it is a car charger of an automobile or a personal computer that is connected may be determined by, for example, a signal output from a USB cable. For example, the USB connector has five lines (VBus / D− / D + / ID / GND). Then, when this ID line is short-circuited to the GND line, it can be determined that the ID line is connected to the personal computer. On the other hand, if the ID line is open (not connected), it can be determined that it is connected to the car charger.

When connected to a car (Yes in step A14: car), the process returns to step A1 and waits until the power is supplied again.

On the other hand, if it is connected to an external device (Yes: external device in step A14), the process proceeds to step A15 to shut down the first control unit 100. This is because when the integrated device 1000 is connected to the personal computer, it is considered unnecessary to execute the navigation function any more. Further, the output of the USB terminal 320 of the personal computer may not be able to cover the current for driving the integrated device 1000.

Then, 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 A16).

After that, it is monitored whether or not it has been removed from the external device (step A17). Then, when the device is removed from the external device (Yes in step A17), the first control unit 100 starts the activation process by supplying power from the lithium ion battery 312 in order to realize the function of the portable navigation system (step A17). A18).

Then, the first control unit 100 displays on the touch panel 110 and executes a navigation function.

As described above, as described with reference to FIG. 13, in the present embodiment, when the engine of the automobile is stopped and the power supply from the car charger is interrupted, when it is removed from the car charger, or 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 as appropriate in each case.
<Car navigation>
Next, the car navigation function by the first control unit 100 will be described in more detail. The first control unit 100 has the current position detected by the GPS sensor 160 and the traffic monitoring point stored in the main storage unit 190. When the positions of the target objects such as the above are in a predetermined positional relationship, a predetermined alarm is output. Therefore, the main storage unit 190 has more attention to information about the target object to be detected (position information of the target object including longitude / latitude, type information of the target object, etc.), accident-prone areas, traffic control information, and the like. There are traffic safety information for safe driving, landmarks and various information useful for driving. Each piece of information is registered in association with a specific type of information (type of target, type of traffic control, accident-prone area, name of landmark, etc.) and location information.

The distance to the target when issuing an alarm can be changed for each type of target. As the mode of the alarm, similarly to the above, there are an alarm by voice or the like using the speaker 120, an alarm using the touch panel 110, and the like. In the present embodiment, since the integrated device 1000 realizes the car navigation function, it has map data.

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

On the other hand, the first control unit 100 for realizing the navigation function also performs the following operations. 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 search for a route (route) from one position to another by using this road network information. In addition, the main storage unit 190 associates a telephone number database with a telephone number database that stores the telephone number and the location information and name of the house, company, facility, etc. of the telephone number, and an address and the location information of the address. It has a stored address database. Further, the main storage unit 190 stores the position information of a traffic monitoring point such as a speed measuring device together with its type.

In addition, the first control unit 100 has a function of performing processing of a general navigation device. That is, the map around the current position is displayed on the touch panel 110 at any time, and the destination setting button 140 is displayed. When the touch panel 110 detects a touch at a position corresponding to the display position of the destination setting button 140, the first control unit 100 performs the destination setting process. In the destination setting process, the destination setting menu is displayed on the touch panel 110, and the user is prompted to select the destination setting method. The destination setting menu has a telephone number search button 140 and an address search button 140 that prompt the user to select a destination setting method. When it is detected that the telephone number search button 140 is touched, the telephone number input screen is displayed, and the position information corresponding to the input telephone number is acquired from the main storage unit 190. When it is detected that the address search button 140 is touched, the 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 the 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 Dijkstra's algorithm can be used.

Then, the first control unit 100 displays the calculated recommended route together with the map of the surrounding area. For example, as shown in FIG. 15, the route i23 from the current position i21 to the destination i22 is displayed in a predetermined color (for example, red) as a recommended route. This is similar to a general navigation system. Then, in the present embodiment, the first control unit 100 compares the position information on the route i23 with the position information of the target object such as the traffic monitoring point stored in the main storage unit 190, and is located on the route i23. Display the location of traffic monitoring points, etc.

As a result, for example, as shown in FIG. 15, 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. 15A is a display example of the warning point search screen, and shows an example in which the traffic monitoring points i25a to i25f are displayed. The traffic monitoring point i25a displays the letter "N" indicating the N system in the balloon. The traffic monitoring points i25b, i25c, and i25e display the characters "LH" indicating the LH system in the balloon. At the traffic monitoring point i25d, the word "loop" indicating the loop coil is displayed in the balloon. The traffic monitoring point i25f displays the letter "H" indicating the H system in the balloon. In this way, when the touch panel 1108 detects a touch to the balloon position in the simplified display state in which characters are displayed in the balloon, the simple display is switched to the detailed display as shown in FIG. 4 (b).

Further, as shown in FIG. 4A, the traffic monitoring point type designation unit i26 is displayed on the lower right side of the touch panel 110. The traffic monitoring point type designation unit i26 is a part that displays a button 140 that lists 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, i25e, and the traffic The "loop" type button 140i27c indicating the loop coil of the monitoring point i25d and the "H" type button 140i27d indicating the H system of the traffic monitoring point i25f are displayed. When the first control unit 100 detects a touch of the type button 140 on the display unit from the touch panel 1108, the first control unit 100 reversely displays the touched type button 140 and a traffic monitoring point corresponding to the touched type button 140. The display mode of is switched to the detailed display if the simple display is in progress, and switched to the simple display if the detailed display is in progress.

The integrated device 1000 of the present embodiment has a peripheral search function as a method of setting a destination (hereinafter, including a waypoint). When this 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. To do. Then, the user can select one of the candidates drawn on the touch panel 110 and confirm it as the destination (including the waypoint).

That is, in order to realize such a function, the main storage unit 190 of the present embodiment stores the information about each facility in association with the information about the classification of the facilities together with the location information. Information on the classification of facilities is a plurality of types of items organized by the names of the genres that each facility matches.

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

When any of the items is selected, the first control unit 100 accesses the main memory unit 190, is a facility existing within a reference distance (for example, 10 km) with respect to the current position, and is designated. Extract items that match the item classification. Then, a predetermined number (for example, 10) of facilities from the closest one are drawn by superimposing an icon (mark) indicating the facility on the corresponding portion on the map drawn on the touch panel 110. As facility information stored in the main storage unit 190, each facility is associated and registered with its own icon, and when drawing, the associated icon is read out and drawn at a predetermined position on the touch panel 110.

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

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

Further, the first control unit 100 has a function of providing route guidance to a set destination. That is, the first control unit 100 draws map information representing a road or the like on the touch panel 110 while sequentially detecting the position of the own vehicle by GPS or autonomous navigation according to the user's selection to start guidance, and the destination. We will guide you to the destination using images and sounds.

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

FIG. 16 is a six-view view showing an example of the appearance of an electronic device on which the integrated device 1000 is mounted. In FIG. 16, the front view is shown in the second row of the central row. Here, in FIG. 16, the surface facing the touch panel 110 when the integrated device 1000 is installed is a front view. A touch panel 110 is arranged in front of the integrated device 1000. Further, buttons 140 and the like are not arranged on the bezel surrounding the touch panel 110 so as not to obstruct the visual inspection of the touch panel 110.

The left side view is shown on the left side of the front view. A first storage unit 180, a notification LED 130b, and a USB terminal 320 are arranged on the left side surface of the integrated device 1000. The first storage unit 180 is realized by an SD slot, and an SD card, which is a storage medium, is inserted into the SD slot. The notification LED 130b is an LED indicating whether or not power is being supplied, and is lit in green, for example, during power supply. A cigar plug cord 504 is connected to the USB terminal 320, and as described in the <battery control> column, the integrated device 1000 receives power from the car charger via the cigar plug cord 504. In order to clarify the shape of the integrated device 1000, the cord portion extending from the socket of the cigar plug cord is not shown in FIG.

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

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. The notification LED 130a is used to indicate whether or not continuous recording is being performed by the integrated device 1000, and is lit in red, for example, when continuous recording is not being performed. The button 140a is a button 140 for starting manual recording, and event recording is started when the button 140a is pressed. Button 140b is a button 140 for stopping or resuming continuous recording, and each time a press is accepted, continuous recording is stopped or restarted. The button 140c is a button 140 for turning on or off the integrated device 1000. When the integrated device 1000 is pressed when the power is on, the integrated device 1000 is turned off, and when the power is turned off, the button 140 is received. The body device 1000 is turned on.

The rear view is shown in the third row of the center row. A camera 210 and a joint portion 502 are arranged on the back surface of the integrated device 1000. Further, an edge 501a, an edge 501b, an edge 501c, and an edge 501d are formed on the back surface of the integrated device 1000. The unit of the camera 210 is incorporated in the integrated device 1000 by a ball joint, and the camera 210 is movable. 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 move 15 degrees upward and 15 degrees downward, for example. The joint portion is a part for attaching the integrated device 1000 to the cradle for fixing the integrated device 1000. Further, the edge 501a, the edge 501b, the edge 501c, and the edge 501d are ridge lines formed on the back surface. The edges 501a, 501b, 501c, and 501d are curved and have a shape that does not get caught in the hands of a user carrying the integrated device 1000.

The 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. The speaker slit 503 is a slit into 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, the integrated device 1000 is provided with four surfaces on the back surface by providing four ridge lines, an edge 501a, an edge 501b, an edge 501c, and an edge 501d, on the back surface as described above. Further, as can be seen by referring to, for example, the bottom view, the top view, the left side view, and the right side view, the shape is such that the camera 210 is used as an apex and a downward inclination is provided with respect to each end portion on the back surface.

In this respect, it is conceivable to realize the housing of the integrated device 1000 as a flat rectangular shape by making the thickness of each end portion and the camera 210 portion the same without providing such an inclination. However, such a shape makes the entire integrated device 1000 large and lacks portability.

Further, the reason why the camera 210 portion becomes thick and the camera 210 portion becomes the apex is due to the size of the camera 210 unit forming the camera 210. Therefore, the camera 210 portion cannot be thinned. On the other hand, the other circuits can be made thinner than the camera 210 portion. Therefore, even if the thickness of each end portion and the thickness of 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, it is not necessary to make the housing of the integrated device 1000 into a flat rectangular shape.

Therefore, in this mounting example, the thickness of the back surface is reduced by providing a downward slope with respect to each end portion of the back surface with the camera 210 as the apex. As a result, it is possible to prevent the material from becoming unnecessarily thick, lacking in portability, and creating wasted space in the housing.

In addition, other features of this implementation example will be described with reference to FIG. FIG. 17A shows the left side surface of the integrated device 1000. As described with reference to FIG. 16, a USB terminal 320 for connecting the cigar plug cord 504 is arranged on the left side surface of the integrated device 1000. A notch 505 is formed in the peripheral right half of the USB terminal 320 when viewed from the left side. Here, the notch 505 when viewed from the left side is substantially vertical from top to bottom up to the height where the USB terminal 320 is provided, but is higher than the height where the USB terminal 320 is provided. The lower part has a curved shape to the left so as to draw an arc.

Further, FIG. 17B shows the back surface of the integrated device 1000. The notch 505 when viewed from the back is different in the left and right length of the upper part (for example, about two-thirds of the whole) and the left and right length of the lower part (for example, about one-third of the whole). ing. Specifically, the left and right lengths of the lower part are shortened.

The reason why the notch 505 has such a shape will be described with reference to FIG. 17 (c). FIG. 17C is a left side view showing a state in which the cigar plug cord 504 is attached to the USB terminal 320. With reference to FIG. 17 (c), the cigar plug cord 504 and the cord portion 504-1 extending from the cigar plug cord 504 are shown.

First, as described with reference to FIG. 17 (b), the notch 505 when viewed from the back has a shorter left and right length of the lower portion, and corresponds to the thickness of the cable. ing. Therefore, when viewed from the back surface, the cord portion 504-1 does not shift to the left or right and follows the shape of the notch 505. The cord portion 504-1 hangs down along a shape curved to the left so as to draw an arc when viewed from the left side surface of the notch 505. That is, the shape curved to the left so as to draw an arc when viewed from the left side surface of the notch 505 guides the cigar plug cord 504 in a desired direction instead of hanging the cord portion 504-1.

By doing so, it is possible to prevent the cord portion 504-1 from moving in an unintended direction. In addition, since the arc is drawn, it is possible to prevent the cord from bending at an acute angle. This makes it possible to extend the life of the cord.

Further, the left and right widths of the notch 505 when viewed from the back surface of the integrated device 1000 are such that the cigar plug cord 504 and the cord portion 504-1 cannot be seen by the user when the integrated device 1000 is viewed from the front. It is good to do. As a result, only the rectangular shape on the front surface of the integrated device 1000 is visible to the user, and a sense of unity is created.

Further, the left and right widths of the notch 505 when viewed from the back surface of the integrated device 1000 are set so that the cigar plug cord 504 and the cord portion 504-1 can be seen by the user when the integrated device 1000 is viewed from the front. Good. As a result, the user can confirm that the cigar plug cord 504 is connected to the USB terminal 320.

In addition, other features of this implementation example will be described with reference to FIG. FIG. 18 is a rear view of the integrated device 1000 and shows the shape when the back surface of the cover that realizes the housing of the integrated device 1000 is removed.

FIG. 18 shows the speaker unit 506, the speaker holding portion 507, and the speaker slit corresponding position 508 representing the position corresponding to the position of the speaker slit 503.

The speaker unit 506 corresponds to the speaker 120 of FIG. 1, and generates sounds for operation guidance, warning sounds, music, and the like by the diaphragm. Here, in general, a sound emitting hole for guiding the sound generated by the diaphragm to the outside of the cover is provided in the portion corresponding to the speaker unit 506 on the back surface of the cover that realizes the housing of the integrated device 1000.

However, in this mounting example, it is assumed that the integrated device 1000 is carried, and the user may see the back surface. In such a case, if the sound emitting hole is provided, the appearance is spoiled.

Therefore, in this mounting example, the speaker holding unit 507 not only holds the speaker unit 506 but also surrounds the periphery of the speaker unit 506. However, the lower part of the speaker unit 506 does not surround the speaker unit 506. As a result, the sound generated by the diaphragm is guided from the lower part of the speaker unit 506 to the speaker slit corresponding position 508, and finally derived from the speaker slit 503. As a result, it is possible to output sound to the outside without providing a sound emitting hole in the portion corresponding to the speaker unit 506 on the back surface of the cover that realizes the housing of the integrated device 1000. As a result, it is possible to prevent the sound emitting holes from spoiling the aesthetic appearance.

Next, in order to fix the integrated device 1000 to the dashboard or the like with reference to FIG. 19, a diagram showing a state in which the integrated device 1000 is attached to the cradle 2000 and the pedestal portion 3000 will be described. In this mounting example, the cradle 2000 can be attached to and detached from the joint portion 502 shown in FIG. 16 and installed on the dashboard of the vehicle together with the cradle 2000 for use, or the integrated device 1000 is removed from the cradle 2000 for portable navigation. Or use it as.

The cradle 2000 is further connected to the pedestal portion 3000. The pedestal part 3000
Support the cradle 2000 in any position. The pedestal portion 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 pedestal portion 3000 and the cradle 2000 are rotatably connected within a predetermined angle range via a connecting mechanism such as a ball joint. Since it is a ball joint, the pedestal portion 3000 and the cradle main body 2000 rotate and move relatively within an arbitrary angular range in the three-dimensional direction, and retain their positions at an arbitrary angular position due to frictional resistance at the joint portion. Therefore, the integrated device 1000 attached to the cradle 2000 can also be arranged in any posture on the dashboard.
<Modification example>
Although the above-described embodiments and implementation examples are preferable embodiments of the present invention, the scope of the present invention is not limited to the above-described embodiments, and various modifications are made without departing from the gist of the present invention. It may be carried out in the form described above.

For example, in the above-described embodiment, the shape of the icon displayed on the map is different depending on the presence or absence of the video file. Also, the colors of the icons displayed on the map were different depending on the level of the event. Furthermore, the events were assigned numbers according to the time series, and the order was displayed numerically. That is, the display mode of each icon is different according to such a condition. Here, different display modes include, for example, different display of icon colors, shapes, sizes, numbers, and the like.

In this respect, the correspondence between the different display modes and the conditions for different display modes is not necessarily limited to the above-described embodiment. For example, it is advisable to make the color of the icon displayed on the map different depending on the presence or absence of the video file. Also, it is advisable to make both the color and the shape different. For example, the numbers of the icons displayed on the map may be different depending on the level of the event. Further, when there is 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 different depending on the condition.

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

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

Further, the oldest file may not be deleted even if a new event occurs in the manual recording and the event recording or the user operates. As a result, new files cannot be protected, but files protected in the past can be prevented from being deleted.

Further, even files protected by manual recording and event recording may be deleted according to user operations and settings. As a result, it is possible to increase the free space of the storage unit by deleting files that are considered unnecessary after checking the contents.

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

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

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

Further, when it is determined that an event has occurred, the event recording may not be performed even if the measured value of the acceleration sensor 170 exceeds any of the 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 minor impact. Therefore, it is possible to prevent a situation in which the number of video files increases too much and the capacity of the storage medium is used up immediately. For example, depending on the vehicle type, road conditions, driving habits, etc., if it is frequently judged that an event with the most sensitive threshold has occurred, recording each time will overwrite the important recorded data immediately. .. Therefore, in such a case, for example, even if it is determined that an event at the most sensitive threshold value has occurred, it is preferable not to store the video file.

Further, since the camera 210 is movable, it is preferable that either or both of the incident positions and directions of the incident portion 211 of the camera 210 can be moved so as to be adjustable. By doing so, it is 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 the image data in a desired range can be captured.

Further, the threshold value for determining that an event has occurred can be set to a different value for each measurement axis, so that the threshold value of the measurement axis corresponding to the traveling direction of the automobile is higher than the threshold value of the other measurement axes. May be good. By doing so, it is possible to use a threshold value according to the usage status of the integrated device 1000, and it is possible to prevent it from being mistakenly determined that an event has occurred when the event has not occurred. It becomes.

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

Therefore, for example, the threshold value may be increased in the measurement axis corresponding to the direction from the front surface to the rear surface of the integrated device 1000. For example, when the integrated device 1000 is installed 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 vehicle traveling direction is the front, the measurement axis corresponding to the vehicle traveling direction is the X direction (front and back), and when the vehicle traveling direction is the front, the measurement axis corresponding to the left and right of the vehicle is the Y direction (left and right). ), The measurement axes corresponding to the top and bottom of the vehicle should be the Z direction (left and right), and the threshold value for the measurement axes in the X direction (front and back) should be increased when the vehicle travel direction is the front.

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

Further, even if the measured value of the acceleration sensor 170 exceeds the threshold value, it is not considered that the event has occurred if the threshold value is exceeded during a predetermined period including when the operation is received by the touch panel 110. It is good to do so. As described above, for example, the value measured by the acceleration sensor 170 increases on the measurement axis corresponding to the direction from the front surface to the rear surface of the integrated device 1000. Since this has nothing to do with the occurrence of the event, it is preferable not to determine that the event has occurred in such a case. Therefore, it is not considered that an event has occurred if it is during a predetermined period including when the operation is accepted. As a result, even when the acceleration sensor 170 measures the impact due to the operation, it is possible to prevent an erroneous determination that an event has occurred based on the measurement. Further, in such a case, it is determined that the event has occurred and the event is recorded, but for example, it is also preferable not to display a pop-up indicating that the event has occurred or output a warning sound. 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 caused by the operation and makes an erroneous determination that an event has occurred.

When the automobile is located near the place where the event occurs, it is preferable to limit at least a part of the functions performed by the integrated device 1000 controlled by the integrated device 1000. By doing so, the user can concentrate on driving the car at the place where the event occurred last time. In places where events have occurred in the past, it is often desirable to be careful and drive. For example, suppose there is a place where it is determined that an event has occurred because the brake was applied suddenly last time. In this case, the functions of the integrated device 1000 to be controlled are partially restricted in the vicinity of this location. For example, it is advisable to limit the audio output function of the television. By doing so, it is possible to stop the output of the TV sound that interferes with driving near the place where the sudden braking was applied before, and the user can concentrate on driving the car.

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

In the above description, it has been described that the event icon and the history icon are displayed on the map including the current position of the automobile in which the integrated device 1000 is installed. In other words, I explained that the map around the car is displayed. In addition to this, when performing a route search or a destination search, it is preferable to display an event icon or a history icon for manual recording and event recording that occurred around the route or the destination. This allows the user to see the icon even for locations that do not include the current location of the car.

Further, it is also preferable to provide operation guidance to the position of the event icon or history icon in response to pressing the event icon or history icon. This makes it possible to easily revisit places where accidents have occurred in the past, where events occur frequently, or where users have manually recorded.

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

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

In the above-described embodiment, it has been described that the software for realizing the control by the first control unit 100 is stored in the main storage unit 190, but a part or all of the software is not the main storage unit 190 but the first. It may be stored in the ROM included in the control unit 100 of the above.

The threshold value may be adjusted by the user, but the threshold value may be fixed in view of the fact that it is generally considered that the user does not know how much the threshold value is adjusted. 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 for example, the icon is a circled number including a number in chronological order. At this time, the numbers may be assigned in descending order or ascending order in chronological order. That is, the latest icon number may be 1 and the oldest icon number may be 10. Further, the latest icon number may be 10 and the oldest icon number may be 1.

In the above description, the video file is 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. Further, the process of decoding the 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 with the "television image" instead of the "camera 210 image". Since it is considered that the user refers to the "camera 210 image" when the integrated device 1000 is installed, but refers to the "television image" after the installation, it is possible to improve the usability of the user.

Further, even when the [Shortcut] button 140 is pressed and the screen S3 is displayed, the voice operation guidance may be continued. As a result, it is possible to prevent the inconvenience that the operation guidance is interrupted.

Further, the button 140 for accepting the operation that triggers the 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, is used instead of the button 140 displayed on the touch panel 110 to accept an operation that triggers manual recording. This eliminates the need to provide the button 140 on the touch panel 110, so that it is possible to prevent, for example, the real-time image displayed in full screen on the screen S13 from being partially obscured by the button 140. ..

In the explanation of FIG. 12, 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. As a result, it is possible to shorten the time until the second control unit 200 is activated.

Further, the acceleration detected by the acceleration sensor 170 differs depending on factors such as an individual driving method, a vehicle type, and a road on which the vehicle always travels. Therefore, in some cases, the threshold value used as a criterion for determining that an event has occurred may be too low. In this case, there is a possibility that an event has occurred even though the event has not occurred. On the other hand, in some cases, the threshold value used as a criterion for determining that an event has occurred may be too high. In this case, it may be erroneously detected that the event has not occurred even though the event has occurred.

Therefore, it is also preferable to allow the user to modify the threshold value set at the time of shipment. Further, in the present embodiment, a plurality of threshold values are provided, and the color of the icon displayed on the map is different depending on which threshold value the acceleration detected by the acceleration sensor 170 exceeds. By doing so, the user can use the icons having different colors as a guideline when individually setting the individual difference of the threshold value depending on the individual driving method, the vehicle type, the road on which the vehicle always travels, and the like.

Further, when it is considered difficult for the user to set the threshold value, it is also preferable to prevent the user from modifying the threshold value set at the time of shipment.

Further, when an SD card or the like is inserted into the second storage unit 230 as a storage medium, the number of moving image data saved according to the storage capacity of the SD card or the like is limited, so that all the icons displayed on the map You can't watch the video. However, it is advisable to distinguish between the latest file in which the video data is stored and the file in the past where the video data is not stored. The distinction may be realized, for example, by making the shapes and colors of the icons different. The latest file may be, for example, 10.
