Description

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

2. Description of the Related Art In recent years, it has become common to use a car navigation device that provides travel guidance to a user who uses a mobile object such as an automobile.

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

The car navigation system described in Patent Document 1 creates information for operation guidance based on the position of the destination, the current position of the own vehicle, the type of road, etc., and creates the information for operation guidance. is superimposed on the map information and displayed on the display unit. This allows the user to reach the destination via an appropriate route.

On the other hand, for the purpose of situation analysis at the time of occurrence of an accident, etc., installation of drive recorders in moving bodies such as automobiles is also being carried out.

The drive recorder includes, for example, a camera for capturing images of the surroundings of the vehicle, an acceleration sensor for detecting abnormalities such as collisions, sudden braking, and sudden steering, and a memory for storing image data captured by the camera. It has a medium.

The camera always stores images of the surroundings while the car is running. When an abnormality such as a collision, sudden braking, or sudden steering is detected based on the output from the acceleration sensor, image data for a predetermined period of time before and after that time is saved in a storage medium. As a result, the user can check the surroundings of the vehicle when an abnormality such as a collision, sudden braking, or sudden steering occurs. An example of such a drive recorder is described in Patent Document 2, for example.

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

JP 2013-160679 A JP 2013-235395 A

As described above, devices such as car navigation devices and drive recorders are used when driving an automobile. Also, a reproducing apparatus such as a personal computer is used to reproduce image data stored in a storage medium by, for example, a drive recorder.

While some of the functions of these devices overlap, such as having a display function, the car navigation system 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 with an acceleration sensor, and the external device has a function to reproduce the image data saved in the storage medium by the drive recorder and to display the location where the image data is stored on the map. Each had its own function, and so on.

However, car navigation devices, drive recorders, and playback devices are each implemented as separate devices, and these unique functions provided by devices used in these mobiles and devices used after using the mobiles It was not supposed to be used in conjunction with each other.

Accordingly, it is an object of the present invention to provide an apparatus and a program that enable cooperative use of functions that were implemented in separate devices.

(1-1) The measurement information that changes with the movement of the mobile object becomes information that satisfies any one of a plurality of conditions provided in stages (hereinafter referred to as "event occurrence"). do),
It is characterized in that two pieces of information are output in association with each event: information specifying the place where the event occurred and information indicating which condition among the plurality of conditions provided in stages is satisfied. device.

By doing so, not only the device concerned, but also "event occurrence determination", "event occurrence place", and "which condition among a plurality of conditions is met, the event occurrence can be performed." It is good because it is possible to obtain at the output destination whether it was determined that the

(1-2) performing control for storing the two pieces of information or controlling for storing the two pieces of information when the event occurs;
It is characterized in that, when a predetermined output condition is satisfied, the stored or stored two pieces of information are output in association with each event.

This makes it 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 they are stored or stored. . Furthermore, in the former case, even if the storage medium inserted in the device is removed, it is possible to read and use these two pieces of information. In the latter case, for example, when the writable capacity of the storage medium inserted in the device becomes full, it is possible to use a new storage medium by replacing it.

As a control for storing the two pieces of information, it is preferable to write the two pieces of information in a storage unit provided in the device itself, for example. The control for storing the two pieces of information may be, for example, writing the two pieces of information in a storage medium inserted in the device or in a storage device connected to the device.

(1-3) the predetermined output condition is outputting information related to the location where the event occurred, including the location where the event occurred and the location where the event occurred; Either or both of

In this way, by setting the predetermined output condition, which is a condition for outputting information, to the approach of the moving body to the location where the event occurred, it is possible for the moving body to approach the location where the event occurred in the past during operation of the moving body. can output information about events that occurred in the past. Furthermore, by setting the output destination to, for example, a display unit or a speaker, the user can grasp that the user is currently approaching a place where an event occurred in the past.

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

(1-4) storing image data captured when the event occurs, when the event occurs, before the event occurs, after the event occurs, or when a combination of two or more of these occurs; The image data can be reproduced after the occurrence of the event by performing control for storing the image data or control for storing the image data.

By doing so, for example, image data captured during a certain period of time before and after the event can be stored, so that the image data captured during the certain period of time before and after the event can be reproduced. Moreover, since there is a combination of two or more of these, it is preferable to use a combination of a certain period of time between when an event occurs and before the event occurs, or a combination of when an event occurs and a certain period of time after the event occurs. Also, the image data may be a still image. Also, the image data may be a moving image. Also, the image data may include data other than still images and moving images. For example, it is preferable to include audio data in the image data.

Further, it is preferable that the image data is generated by imaging by the imaging means. The imaging means and the device may be connected. Furthermore, a device contained in the same housing as the device may be controlled by the device. An imaging device may be included in such a device to be controlled.

Also, 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 above in (1-2), for example.

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

At the output destination, it is possible to grasp which event has corresponding image data. In addition, by setting the output destination to, for example, a display unit or a speaker, a user who refers to the output information can not only know where the event occurred, but also ask whether the image data corresponding to the event can be reproduced at present. state” can also be grasped.

(1-6) When it is determined that the event has occurred, control is performed so as not to execute a function that is to be executed by a device to be controlled by the device and that interferes with capturing of the image data. characterized by

By doing so, it is possible to pick up the image data without obstacles. For example, the device to be controlled by the device is a device capable of reproducing TV video, and the function executed by the device to be controlled by the device that interferes with capturing the image data is the sound of the TV. It is preferable to use it as an output function. By doing this, 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 capturing of the image data may be the operation of the wiper. . By doing this, when 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 appearing in the image data.

(1-7) having a deletion function of deleting the stored or stored image data;
Even if image data corresponding to a certain event is deleted by the deletion function and cannot be reproduced, the information specifying the location where the event occurred and the stepwise provided information It is characterized by outputting two pieces of information indicating which of a plurality of conditions is satisfied.

By doing so, it is possible to output two pieces of information even after deleting the image data. Also, these two pieces of information can be used at the output destination. Therefore, even if the image data has been deleted and cannot be reproduced, the user can confirm the place where the event occurred and the degree of impact at the time of the event occurrence.

(1-8) performing control for storing the image data or controlling for storing the image data when a first condition among the plurality of conditions is satisfied;
When a second condition out of the plurality of conditions is satisfied, control for storing the image data or control for storing the image data is not performed, but the place where the certain event occurred is specified. and information indicating which condition among the plurality of conditions provided step by step is satisfied.

In this way, it is preferable not to store the image data even if any one of the plurality of conditions is satisfied. Thus, for example, when it is frequently determined that an event has occurred based on a light impact, image data is not stored even if it is determined that an event has occurred based on a light impact. Therefore, it is possible to prevent a situation in which the capacity of the storage medium is quickly exhausted due to an excessive increase in image data. For example, depending on the vehicle type, road conditions, driving habits, etc., if it is often determined that an event with the most sensitive threshold has occurred, recording every time will overwrite the important recorded data immediately. . Therefore, in such a case, it is preferable not to store the image data even if it is determined that an event has occurred with the most sensitive threshold value. In this case, the image data is not stored, but the two pieces of information are output. Therefore, the user can confirm the place where the event occurred and the degree of impact when the event occurred.

(1-9) performing control for displaying a symbol specifying the place where the event occurred, and performing control for varying the display mode of the symbol depending on whether or not the image data is stored; characterized by performing

By doing so, the information to be output can be visualized, and for example, a user who refers to this can grasp the content of the information. Specifically, a user who refers to the symbol can grasp not only the place where the event occurred, but also which event has image data stored. Here, the specific type of the symbol is arbitrary, but for example, the symbol may be an icon displayed on a map. As a result, the user can refer to the location where the event occurred by comparing the map with the location where the event occurred, thereby facilitating recognition of where the event occurred.

Also, how to change the display mode of the symbol is arbitrary. A rectangular icon may be used as the symbol for identifying the place where an unstored event has occurred. Further, it is preferable to use different colors for the symbol specifying the location where the event occurred and the symbol specifying the location where the event for which the image data is not stored occurred. Also, it is preferable that both the shape and color of the icon are different between the symbol specifying the place where the event occurred and the symbol specifying the place where the event where the image data is not stored occurred.

(1-9-1) The size of the symbol specifying the place where the event in which the image data is stored is larger than the size of the symbol specifying the place where the event in which the image data is not stored is generated. 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 this can grasp the content of the information. Here, the symbol is the same as in (1-9) above, and may be an icon displayed on the map, for example.

Also, how to change the shape of the symbol is arbitrary. A circular icon smaller than this certain size may be used as a symbol for identifying the place where an event in which image data is not stored has occurred.

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

In either case, the user who refers to this can grasp not only the place where the event occurred but also which event the image data is stored for.

(1-10) Receiving an operation is required to perform control for stopping the imaging of the image data during reproduction of the image data, and to perform control for resuming the imaging of the image data after the reproduction of the image data is completed. It is characterized by performing 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 image data reproduction.

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

Furthermore, after preventing such a situation, by resuming the imaging of the image data without requiring the acceptance of the operation, the recording can be resumed even if the user forgets the operation for starting the recording. becomes possible. In addition, it is possible to save the trouble of the user performing an operation.

(1-11) a device to be controlled by the device comprises imaging means for capturing the image data;
Even after the device to be controlled is installed on the moving body, the incident portion for incident light to the imaging means can be moved so that either or both of the incident position and 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 image data of a desired range can be imaged. A device contained in the same housing as the device may be controlled by the device. An imaging device may be included in such a device to be controlled. For example, the imaging means may be a camera, and the incident portion may be a camera lens, for example.

(1-12) performing control for displaying a symbol specifying the place where the event occurred, and displaying the symbol according to which one of the conditions provided in stages is satisfied; It is characterized by performing control for changing the display mode of.

By doing so, the information to be output can be visualized, and for example, a user who refers to the information can grasp which conditions each event is determined to have occurred by satisfying. It becomes possible. Here, the symbols are the same as in (1-9) and (1-9-1) above, and may be icons displayed on a map, for example.

In addition, any color can be used to make the color of the symbol different. do it. Also, for example, when it is determined that an event has occurred due to a large impact, the event may be colored red. Also, for example, if it is determined that an event has occurred due to an intermediate impact between these fine impacts and large impacts, the event may be colored yellow. Also, the size and shape of the icon may be changed according to the magnitude of the impact.

Also, by combining with (1-9) and (1-9-1) described above, both the size and shape of the icon may be changed according to the presence or absence of image data.

Also, when associating with the configurations of (1-9) and (1-9-1) described above, it is preferable to vary the manner of making a difference according to the content. For example, the "shape" of the icon may be changed according to whether or not image data exists, and the "color" of the icon may be changed according to the magnitude of the impact. Also, it is preferable to change the "color" of the icon depending on whether or not image data exists, and to change the "shape" of the icon according to the magnitude of the impact.

(1-13) Triggered by the reception of a predetermined operation, control for storing information identifying the location where the predetermined operation was received separately from information identifying the location where the event occurred, or performing control to store information specifying the place where the predetermined operation is accepted separately from information specifying the place where the event occurred;
The control is performed to display the symbol specifying the place where the operation is received in a different display mode from the symbol specifying the place where the event occurred.

This makes it possible to store (store) position information even when it is not determined that an event has occurred. By doing so, the information to be output can be visualized, so that the user who refers to this can distinguish between the location where the event is determined to have occurred and the location where the operation has been performed. becomes possible.

Here, the symbols are the same as those in (1-9), (1-9-1) and (12) above, and may be icons displayed on a map, for example.

Also, any color can be used to make the color of the symbol different.

Also, by combining with (1-9) and (1-9-1) described above, both the size and shape of the icon may be changed according to the presence or absence of image data. Furthermore, in combination with the above (1-12), it is also possible to change the color of the icon according to which condition the event is determined to have occurred by satisfying which condition. good.

Also, 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 above in item (2), for example.

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

By doing so, the output destination can grasp which event was determined to have occurred recently and which event was determined to have occurred in the past.

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

It is also possible to combine with (1-9), (1-9-1), (1-12) and (1-13) described above.

For example, in combination with (1-9-1) above, for example, icons may be circled numbers displaying numbers in chronological order.

(1-15) The measurement information that changes along with the movement of the moving object includes a measurement value obtained by an acceleration sensor, and the plurality of threshold values are determined depending on which of the stepwise provided threshold values the measurement value obtained by the acceleration sensor exceeds. It is determined which one of the conditions of (1) is satisfied.

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

(1-16) Even if the measurement information that changes along with the movement of the moving object becomes information that satisfies any one of a plurality of conditions provided in stages, it becomes information that satisfies the condition. If it is during a predetermined period including the time when the operation is accepted, it is not determined that the event has occurred, or it is determined that the event has occurred, but a warning to the effect that the event has occurred is output. is characterized by not performing control of

An 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 erroneous determination that an event has occurred when no event has occurred.

Depending on how the device is used, the value measured by the acceleration sensor may increase in a predetermined direction regardless of the occurrence of an event. For example, when the front surface of the device is a touch panel, when the user presses the touch panel, the measurement value of the acceleration sensor increases in 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 event occurrence, it is better not to judge that an event has occurred in such a case.

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

However, there may be cases where an event actually occurs before or 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 becomes possible to reliably perform the processing that is performed in association with the occurrence of the event. The processing that is performed in association with the occurrence of an event may be, for example, image data storage processing. On the other hand, it is possible to prevent a situation in which a warning is output even though the accelerometer measures the impact accompanying the operation and erroneously determines that an event has occurred. .

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

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

For example, a device to be controlled has substrates that implement two functions, and it is preferable that 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, it is preferable to use a board that implements the function of a car navigation system and a board that implements the function of a drive recorder. For example, image data captured by a board that realizes the function of a drive recorder can be reproduced by the ability of the board that realizes the function of a car navigation system, or if the capacity of the storage medium used by one board becomes full. , the other storage medium can be used.

(1-18) Also output measurement information measured at the time of occurrence of the event, before the occurrence of the event, after the occurrence of the event, or at a combination of two or more thereof.

By doing so, the output destination can grasp the measurement information measured in a certain period before and after the event occurrence. Moreover, since there is a combination of two or more of these, it is preferable to use a combination of a certain period of time between when an event occurs and before the event occurs, or a combination of when an event occurs and a certain period of time after the event occurs.

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

(1-19) The program is characterized by causing the computer to function as the device described in (1) to (1-18) above.

All or at least part of the functions of the apparatus described as (1-1) to (1-18) above can be realized by a computer.

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

For example, the maximum storable number of image data is determined based on the capacity of the storage medium, and the state in which the number of image data close to this maximum storable number is stored (or is being stored) is A predetermined number of the image data may be stored (or stored).

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

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

By doing so, it is possible to use a threshold value according to the usage state of the device, and to prevent erroneous determination that an event has occurred when no event has occurred.

In this regard, depending on how the device is used, the value measured by the acceleration sensor may increase in a predetermined direction regardless of the occurrence of an event. For example, when the front surface of the device is a touch panel, when the user presses the touch panel, the measurement value of the acceleration sensor increases in 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 event occurrence, it is preferable not to judge that an event has occurred in such a case. Therefore, for example, it is preferable to increase the threshold in the measurement axis corresponding to the direction from the front surface to the rear surface of the apparatus. This makes it possible not to determine that an event has occurred even if some impact is detected.

Further, for example, when the device is installed in a car, the front face of the device provided with the touch panel faces the front of the user, and the rear face of the device faces the traveling direction of the car. Therefore, for example, when the traveling direction of the moving body is the front, the measurement axis corresponding to the traveling direction of the moving body is the X direction (front and back), and when the traveling direction of the moving body is the front, the measurement axis corresponding to the left and right of the moving body is set. The Y direction (left and right) is set, and the measurement axis corresponding to the top and bottom of the moving body is the Z direction (left and right) when the traveling direction of the moving body is the front, and the threshold value for the measurement axis in the X direction (front and back) is increased. do it.

(1-c) When it is determined that the event has occurred, control is performed to turn on the notification unit, and the notification unit is installed in a place where the lighting by the notification unit is reflected on the windshield of the moving object. characterized by

By doing so, the lighting or blinking reflected on the windshield can be seen, and the user can easily recognize that an event has occurred. For example, when driving a mobile object at night, the notification unit may be turned on.

(1-d) It is characterized in that, when the mobile object is located near the place where the event occurred, at least part of the functions executed by the device to be controlled by the device is restricted.

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

In many cases, it is desired to drive carefully in a place where an event has occurred in the past. For example, assume that there is a place where it is determined that an event has occurred due to sudden braking the previous time. In this case, the functions of the device to be controlled are partially restricted in the vicinity of this location. For example, as in (6) above, the device to be controlled is a device capable of reproducing television images, and the function executed by the device to be controlled by the device is a function that interferes with capturing the image data. , may be used as the audio output function of the television. By doing so, it is possible to stop the output of the television sound that disturbs driving in the vicinity of the place where the brake was suddenly applied before, so that the user can concentrate on driving the mobile object.

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

In this way, by sequentially applying the voltage and causing the current to flow stepwise, it is possible to reduce the maximum total value of the required current. This makes it possible to start the device even with a low current power supply. In addition, since the first power consuming unit that controls either or both of the control for outputting information to the user and the control for accepting an operation from the user is first targeted for application, The user can quickly start referring to information and performing operations.

Also, for example, it is preferable to supply power from the outside using a car charger of a moving body. This allows the use of lower current car chargers and reduces costs. Also, low-current car charger cables are thin, making them easier to handle for the user.

(2-2) the second power consuming unit has a part that needs to receive power from a battery and perform a predetermined operation termination process when power from the external power supply is interrupted;
It is characterized in that a 1-2 application of applying a voltage to the capacitor is performed before performing the second application.

By doing so, the power is supplied to the capacitor before the second power consumption unit is activated, and the charge for the second power consumption unit to perform the predetermined operation termination process is stored in the capacitor. be able to. Therefore, the required predetermined operation end processing can be reliably executed.

The operation ending process may be, for example, a process of storing the data being processed by the second power consuming unit in the storage medium. As a result, it is possible to prevent the files in the middle of processing from being damaged.

(2-3) The device includes a secondary battery for continuing to drive when removed from the external power source, and a second voltage is applied to the secondary battery after the second application. 3 is applied.

A large amount of current is still consumed immediately after the application to the second power consumption section starts. Therefore, if current flows through the secondary battery at this stage, it will exceed the rated current of the external power supply.

Therefore, by preventing the third application from being performed immediately, it is characterized by preventing the current from exceeding the rated current of the external power supply.

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. Also, the capacitor may be a supercapacitor.

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

When providing various functions to the user, power consuming units that take a long time to perform their functions are prioritized over power consuming units that do not require a relatively long time to perform their functions. Voltage should be applied. Therefore, voltage is applied to the first power consumption section, which takes a relatively long time to perform a predetermined function, before the voltage is applied to the second power consumption section. This enables the user to use the function exhibited by the first power consuming unit early. As described in section (2-1) above, the first power consuming unit Since either or both of control for outputting information to and control for accepting an operation from the user is performed, by making the first power consumption unit the target of application first, The user can quickly start referring to information and performing operations.

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

In addition, since the power is applied to the first power consumption unit first, the map display function can be quickly activated. It is conceivable that the user of the mobile object often starts driving after confirming the map. Also, if the vehicle has not started driving, the need for the drive recorder to function is lower than during driving. Therefore, for example, instead of activating the drive recorder function first, the drive recorder function should be activated after the map display function is activated. As a result, it is possible to set the activation order suitable for the user's usage.

(2-6) It is characterized by performing control for performing operation guidance to a place specified by the position information acquired in relation to the drive recorder function.

By doing so, the user receives driving directions to the locations associated with 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 frequently occurs, or a place manually recorded by the user.

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

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

(2-8) Control so that the second application is started when the voltage of the capacitor exceeds the first predetermined voltage, and the voltage of the capacitor exceeds the second predetermined voltage. If , the control is performed so that the second power consumption unit can exhibit a predetermined function.

If the second power consuming unit immediately executes a predetermined function even after the start-up process of the second power consuming unit is finished, it is conceivable that the power storage in the capacitor is insufficient. 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 capable of executing the predetermined function. As a result, it is possible to prevent the predetermined function from being executed despite insufficient power storage in the capacitor. The predetermined function may be, for example, a drive recorder function.

(2-9) It is characterized in that the second power consumption section performs control so that the third application is performed when the predetermined function becomes executable.

Immediately after the application to the second power consuming unit starts, the storage of electricity in the capacitor is still insufficient, and a large amount of current is being consumed. Therefore, if a current is passed through a secondary battery, which is another device, at this stage, the maximum value of the total current will exceed expectations.

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

(2-10) The first power consuming unit operates during any or all of the periods from the start of power supply from the external power supply to the start of the third application. 2 is not in a state capable of performing the predetermined function.

As described in column (2-1) above, 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. By doing so, it becomes possible for the first power consumption unit to output that the predetermined function of the second power consumption unit cannot be used yet. For example, it is preferable to output a message such as "Currently the drive recorder function cannot be used" on the display unit. This allows the user to recognize that the power supply has started properly and that the predetermined function of the power consumption unit 2 is in the process of starting.

(2-11) Control is performed so as to stop a predetermined function operating on the second control unit when the supply of power from the outside is interrupted.

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

(2-12) When the device is receiving power from the predetermined external power supply, the function of operating on the first power consumption unit and the function of operating on the second power consumption unit It is characterized by stopping the function.

By doing so, it is possible to reduce power consumption and efficiently charge the secondary battery.

For example, when receiving power from a device other than a mobile device, it is assumed that the device is not being used by the mobile device and is connected to a USB (Universal Serial Bus) terminal of a personal computer or an outlet. . In this case, the map display function becomes unnecessary in addition to the function as a drive recorder. Therefore, by doing so, unnecessary functions can be stopped, and the consumption of the secondary battery can be reduced.

(2-13) The program is characterized by causing the computer to function as the device described in (2-1) to (2-13) above.

All or at least part of the functions of the apparatus described as (2-1) to (2-13) above can be realized by a computer.

(2-a) A device characterized by controlling the secondary battery to apply a voltage to the first power consumption unit when power supply from the external power source is interrupted.
When it is cut off, for example, when it is removed from a car charger of a moving object, the function as a drive recorder becomes unnecessary. Therefore, voltage is applied from the secondary battery to the first power consumption unit realizing the map display function instead of the second power consumption unit realizing the function of the drive recorder. By doing so, it is possible to immediately use the map display function even if the supply of power from the outside is interrupted. Also, it is preferable that the device is portable so that the user can carry it around and use it.

According to the present invention, functions implemented in separate devices can be used in cooperation with each other.

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

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

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

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

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

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

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

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

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

The first storage unit 180 is a part into which a removable storage medium is inserted by the user. In the first storage unit 180, for example, a storage medium storing music files in MP3 (MPEG-1 Audio Layer-3) format and television images written by the first control unit 100 is inserted. 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 .

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

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

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

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

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

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

Camera 210 includes an incident portion 211 .

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

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

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

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

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

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

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

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

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

Next, constant recording will be described. The real-time video is stored in the second storage unit 230 from the start of acquisition of the real-time video to the end of acquisition of the real-time video. In other words, while the engine of the automobile is running, recording is always performed. The recorded real-time video is divided into a plurality of files in units of a predetermined length and stored in the second storage unit 230 . Although the unit of the predetermined length is arbitrary, for example, one file may be set in units of 30 seconds. Note that this file will be referred to as a "video file" in the following description.

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

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

Next, manual recording will be described. Manual recording is executed when it is detected that the button 140 has been pressed by the user. Then, the video file including the point at which the depression of the button 140 is detected and the video file immediately before that video file are protected. In other words, two video files are protected by pressing once. Here, being protected means that the protected video file is excluded from deletion of the oldest video file by continuous recording.

Then, the two protected video files, the dates and times when the two video files were captured, and the position information specifying the positions where the two video files were captured are linked and stored in the second storage unit 230 as a set. In order to identify this set, it is necessary to add an identification code to the 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 better to As the position information, it is preferable to request the first control unit 100 for the coordinate information measured by the GPS sensor 160, and use the coordinate information transmitted from the first control unit 100 in response to the request.

Furthermore, the second control unit 200 notifies the first control unit 100 that manual recording has occurred. Specifically, the fact that the manual recording has occurred, the date and time of the manual recording, and the position information specifying the position of the manual recording are linked together and sent to the first control unit 100 as a set. Then, the first control unit 100 stores the received set of information in the main storage unit 190 .

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

Next, event recording will be described. When the first control unit 100 determines that an event has occurred, event recording is performed. The criteria by which the first control unit 100 determines that an event has occurred will be described after the event recording.

Then, the video file including the point in time when the event occurred and the video file immediately before that video file are protected. In other words, two video files are protected according to one occurrence of an event.

Then, the two protected video files, the dates and times when the two video files were captured, and the position information specifying the positions where the two video files were captured are linked and stored in the second storage unit 230 as a set. Also, as with manual recording, it is preferable to use the dates and times when the two video files were captured as identification codes. Furthermore, as for the position information, it is preferable to use the coordinate information transmitted from the first control unit 100 as in the case of manual recording. Also, as in manual recording, it is preferable to use coordinate information transmitted from the first control unit 100 as position information.

As with manual recording, the number of cases that can be protected may be arbitrarily determined according to the capacity of the second storage unit 230. It is good to set it as the capacity|capacitance for 20 pieces. As in the case of manual recording, if 20 video files are protected and recording is to be performed, the oldest two video files should be removed from the protection target and deleted.

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

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

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

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

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

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

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

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

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

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

An area i4 shown in FIG. 4 is provided with an area in which various types of information used for operation guidance are displayed. In the example shown in FIG. 4, the current time obtained from GPS satellites, the GPS signal reception strength and direction, a value representing the scale of the map, and a shortcut button 140 are arranged in this area from the top.

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

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

Further, in i6 shown in FIG. 4, the address, road name, latitude and longitude of the place where the vehicle in which the integrated device 1000 is installed is currently running are displayed. It is also possible to display the menu screen 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, a display method according to this embodiment will be described. In this embodiment, the positions where event recording was performed due to the occurrence of an event and the positions where manual recording was performed according to the user's operation are displayed, for example, as icons on the map for operation guidance displayed by the car navigation system function. . Note that this icon will be called an "event icon" in the following description.

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

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

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

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

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

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

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

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

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

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

FIG. 5 shows a specific example of displaying event icons with these contents.

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

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

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

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

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

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

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

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

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

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

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

Next, the history icon, which is an icon separate from the event icon, will be described. As described above, 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 exceeds 10, the video files are deleted in order from the oldest. Therefore, the event icon corresponding to the deleted video file is also deleted.

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

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

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

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

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

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

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

FIG. 7 shows a specific example of displaying event icons with these contents. In the specific example of FIG. 7, the video file corresponding to the event icon shown in the specific example of FIG. 5 is deleted and replaced with the history icon because it has become old.

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

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

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

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

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

By displaying not only the event icon but also the history icon in this manner, the user can grasp the location where the event frequently occurs.
<Screen transition>
Next, how the screen transitions according to the state of the vehicle and the user's operation will be described with reference to the transition diagrams of FIGS. 8 to 10. FIG.

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

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

On the screen S2, as described with reference to FIGS. 5 and 7, an event icon and a history icon are displayed on a map for operation guidance, and operation guidance is executed with voice output. The content of such display is the content described in the section <Display Method> above. Also, the method of determining the occurrence of an event by the first control unit 100, the operation at the time of occurrence of the event, and the like are the contents described in the section <Occurrence of event> above. Assume 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 the real-time image, which is the image currently captured by the camera 210, is displayed on the screen. In this state, when the user presses the [End] button 140, the screen transitions to the screen S2, and the operation guidance is executed again.

Further, when any [icon] button 140 is pressed in the state of the screen S2, the process for reproducing the video file corresponding to the pressed event icon or history icon is started. Specifically, the screen is shifted to the screen S4, a message indicating that the continuous recording will be temporarily interrupted is output, and the user's selection of the button 140 of either [Yes] or [No] is accepted.

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

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

Here, if the user presses the [No] button 140, the screen transitions to S2, and operation guidance is continued.

On the other hand, if 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, the user does not want to reproduce the video file corresponding to the icon selected from the event list on the screen S5, but wants to reproduce the video file corresponding to the icon selected on the screen S2.

Therefore, the entire event list is treated as the [event item] button 140, and when the [event item] button 140 is pressed for the first time, the map is moved to the coordinates of the icon selected on the screen S2. Further, when the [event item] button 140 is pressed for the second time, the screen is changed to the screen S6 and the moving image reproduction is started.

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

When the user presses the [Return] button 140 during or after shooting, the screen transitions to the screen S5. Then, when the pressing of the [Back] button 140 is accepted on the screen S5, the screen transitions to the screen S2, and operation guidance is continued. In addition, constant recording is resumed without requiring user's operation.

Next, as described above, when any [icon] button 140 is pressed in the state of the screen S2, instead of playing back the video file corresponding to the pressed icon, the user selects the icon from the event list. is selected, and the operation of reproducing the video file corresponding to the icon selected from the event list will be described.

When the [MENU] button 140 provided at the bottom of the screen is pressed in the state of the screen S2, the screen transitions to the screen S8, which is the menu screen of the navigation function.

After that, when the 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 a menu screen for registration/editing.

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.

In the screen S10, similarly to the screen S4, a message indicating that the continuous recording will be temporarily interrupted is output, and the user selects either [Yes] or [No] button 140. The reason why the continuous recording is temporarily interrupted is as described in the description of the screen S4.

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

On the other hand, when the user presses the [Yes] button 140, the screen transitions to the screen S11, and the event list is displayed on the right half of the screen as described with reference to FIG. Unlike the screen S5, the user has not selected an icon on the screen S2, so the user's icon selection from the event list on the screen S5 is accepted.

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

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

First, when the [drive recorder] button 140 is pressed on the screen S1, the screen transitions to the screen S12 or screen S13 shown in FIG. Here, regarding the condition for transitioning to which screen, the all-in-one device 1000 is not installed in the automobile and the all-in-one device 1000 is receiving power from the secondary battery included in the power supply unit 310. to the screen S12. On the other hand, if the integrated device 1000 is installed in the vehicle and the integrated device 1000 is receiving power from the vehicle, the screen transitions to S13.

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

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

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

Then, the [Exit Application] button 140 is displayed on the screen S14. When the user presses the [Exit application] button 140, the operation of the application that implements the drive recorder function is terminated, and the screen transitions to screen S1. On the other hand, when the pressing of the screen is accepted in the screen S14, the screen returns to the screen S13 again, and the real-time video is reproduced in full screen display. In the screen S14, for example, a button 140 for changing the settings is displayed, and when the button 140 for changing the settings is pressed, the screen further transitions to a screen for performing various settings related to the drive recorder function, for example. do it.

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

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

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

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

Next, with reference to FIG. 11, the detailed configuration of power supply section 310 will be described. Referring to FIG. 11, the power supply unit 310 includes a power control unit 311, a lithium ion battery 312, and a supercapacitor 313 (registered trademark). Also, the power supply unit 310 is connected to the first control unit 100 and the second control unit 200 . Of the functional blocks shown in FIG. 1, functional blocks that are not directly related to the description of battery control are omitted from FIG.

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

Here, the power control unit 311 has a function of controlling to which device a voltage is applied. The power control unit 311 is implemented by, for example, a power management IC. Also, the first control unit 100 may perform part or all of the control of the power supply control unit 311 . In FIG. 11, signal lines for transmitting and receiving signals for the first control unit 100 to control the power supply control unit 311 are indicated by dashed lines. On the other hand, lines for applying voltage are shown in FIG. 11 as solid lines.

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

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

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

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

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

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

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

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

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

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

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

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

Next, the power supply control processing of this embodiment will be described in detail with reference to the flowcharts of FIGS. 12 and 13. FIG.

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

Then, the power control unit 311 starts applying voltage to the first control unit 100 . As a result, the first control unit 100 starts activation processing (step 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 . A screen S1 shown in FIG. 8 is displayed at this time. Then, when the [navigation] button 140 is pressed, the navigation function is executed (step A3). Also, even if the [drive recorder] button 140 is pressed, the drive recorder function is not yet executed. Therefore, a message such as "The drive recorder is being activated. Please wait for a while." is displayed on the screen as in the screen S14 shown in FIG. Then, after a predetermined period of time has elapsed during which it is considered that the user can recognize this message, it is determined that a time-out has occurred, and the screen transitions to screen S1. In this way, first, by activating the first control unit 100 and displaying on the touch panel 110, it is possible to notify the user that the activation process is being performed.

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

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

However, if the drive recorder function is executed, the maximum current may exceed the rated current of the cigar plug cord. Therefore, the second control unit 200 performs activation processing, but does not yet execute the function of the drive recorder. Therefore, even if the [Drive Recorder] button 140 is pressed at this time, a message such as the screen S14 shown in FIG. 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 supercapacitor 313 is higher than a predetermined second voltage (step A7). Here, the predetermined second voltage is a value higher than the predetermined first voltage.

Then, when the current voltage of supercapacitor 313 becomes higher than the predetermined second voltage (Yes in step A7), it means that supercapacitor 313 is sufficiently charged, and a large amount of current is accumulated in supercapacitor 313. is no longer necessary. Therefore, when step A7 becomes Yes, the process proceeds to step A8, and the second control unit 200 executes the drive recorder function (step A8). Further, the power control unit 311 starts applying voltage to the lithium ion battery 312 . Thereby, charging of the lithium ion battery 312 is started (step A9).

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

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

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

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

The integrated device 1000 executing the navigation function and the drive recorder function continues to monitor whether or not the power supply from the car charger is interrupted as the engine of the car stops. Further, it continues to monitor whether or not the integrated device 1000 has been 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 (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), shutdown processing of the first control unit 100 and the second control unit 200 is performed. At this time, the shutdown processing of the first control unit 100 is performed by power supply from the lithium ion battery 312 , and the shutdown processing of the second control unit 200 is performed by power supply from the supercapacitor 313 . Then, the process returns to step A1 and waits until the power is supplied again.

On the other hand, when integrated device 1000 is removed from the car charger by removing the cigar plug cord from USB terminal 320 or by removing the cigar plug cord from the car charger (Yes in step A12), the second The controller 200 starts shutdown processing by power supply from the supercapacitor 313 . By doing so, the user cannot use the drive recorder function, but since the first control unit 100 does not particularly shut down, the user can continue to use the navigation function. In other words, the integrated device 1000 can be used as a portable navigation system. Note that the first control unit 100 continues to operate by power supply from the lithium ion battery 312 . Since only one of the two controllers can be shut down in this manner, the other controller does not need to be shut down and restarted, and can continue to operate.

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

If it is connected to an automobile (Yes in step A14: automobile), the process returns to step A1 and waits until power is supplied again.

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

After shutting down the first control unit 100, charging of the lithium ion battery 312 is started in preparation for using the integrated device 1000 as a portable navigation system again (step A16).

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

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

As described above with reference to FIG. 13, in this embodiment, when the vehicle engine stops and the power supply from the car charger is interrupted, when the car charger is removed from the car charger, and when it is connected to an external device, In each case, the first control unit 100 and the second control unit 200 can be driven or shut down as appropriate.
<Car navigation>
Next, the car navigation function of the first control unit 100 will be described in more detail. A predetermined alarm is output when the positions of the target objects such as the above are in a predetermined positional relationship. Therefore, the main storage unit 190 stores information on targets to be detected (target position information including longitude and latitude, target type information, etc.), accident-prone areas, traffic control information, and the like. There is traffic safety information for safe driving, landmarks, and various information useful for driving. Each piece of information is registered by associating specific types of information (types of targets, types of traffic enforcement, accident-prone areas, names of landmarks, etc.) with location information.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

16A and 16B are six views showing an example of the appearance of an electronic device in which the integrated device 1000 is mounted. In FIG. 16, the front view is shown in the second stage of the center row. Here, in FIG. 16, the front view is the surface facing the touch panel 110 when the integrated device 1000 is installed. A touch panel 110 is arranged on the front of the integrated device 1000 . Further, the bezel surrounding the touch panel 110 is not provided with the buttons 140 and the like, so that the touch panel 110 is not obstructed.

A left side view is shown to the left of the front view. A first storage unit 180, an informing LED 130b, and a USB terminal 320 are arranged on the left side of the integrated device 1000. As shown in FIG. The first storage unit 180 is implemented by an SD slot, into which an SD card as a storage medium is inserted. The notification LED 130b is an LED that indicates whether or not power is being supplied, and lights green, for example, during power supply. A cigar plug cord 504 is connected to the USB terminal 320, and the integrated device 1000 receives power from the car charger via the cigar plug cord 504 as described in the <Battery Control> section. In order to clearly show the shape of the integrated device 1000, FIG. 15 omits illustration of the cord portion extending from the socket of the cigar plug cord.

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

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

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

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

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

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

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

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

Other features of this implementation will also be described with reference to FIG. The left side of the integrated device 1000 is shown in FIG. 17(a). As described with reference to FIG. 16, the USB terminal 320 for connecting the cigar plug cord 504 is arranged on the left side of the integrated device 1000 . A notch 505 is formed in the right half of the USB terminal 320 when viewed from the left side. Here, when viewed from the left side, the notch 505 is substantially vertical from top to bottom up to the height at which the USB terminal 320 is provided. The lower part has a shape that curves to the left as if drawing an arc.

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

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

First, as described with reference to FIG. 17(b), the notch 505 when viewed from the rear side has shorter left and right lengths at the lower portion, corresponding to the thickness of the cable. ing. Therefore, when viewed from the rear side, the cord portion 504-1 follows the shape of the notch 505 without shifting to the left or right. When the cord portion 504-1 is viewed from the left side of the notch 505, the cord portion 504-1 hangs along a shape that curves to the left like drawing an arc. In other words, the shape of the notch 505 that curves to the left like an arc when viewed from the left side guides the cord portion 504-1 of the cigar plug cord 504 in a desired direction rather than causing it to hang down.

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

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

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

Other features of this implementation will also be described with reference to FIG. FIG. 18 is a rear view of the integrated device 1000 and shows the shape when the rear portion of the cover that realizes the housing of the integrated device 1000 is removed.

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

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

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

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

Next, referring to FIG. 19, a diagram of a state in which the integrated device 1000 is attached to the cradle 2000 and the base portion 3000 in order to fix the integrated device 1000 to a dashboard or the like will be described. In this implementation example, the cradle 2000 is detachable from the joint portion 502 shown in FIG. Use as

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

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

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

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

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

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

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

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

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

Furthermore, when it is determined that an event has occurred, it is preferable to perform control so as not to execute a function that hinders real-time video imaging. The function that hinders real-time video imaging is, for example, the audio output function of a television. By doing this, when image data is captured, the 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 data to be captured.

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

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

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

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

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

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

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

It is preferable to limit at least part of the functions executed by the integrated device 1000 to be controlled by the integrated device 1000 when the vehicle is located near the location where the event occurred. By doing so, the user can concentrate on driving the car at the location where the event occurred last time. In many cases, it is desired to drive carefully in a place where an event has occurred in the past. For example, assume that there is a place where it is determined that an event has occurred due to sudden braking the previous time. In this case, the function of the integrated device 1000 to be controlled is partially restricted in the vicinity of this location. For example, it is good to limit the audio output function of the TV. By doing this, it is possible to stop the output of the television sound that disturbs the driving near the place where the driver suddenly applied the brake, so that the user can concentrate on driving the car.

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

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

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

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

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

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

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

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

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

In the above description, the [shortcut] button 140 may be associated with "television image" instead of "camera 210 image". The user will refer to the "camera 210 image" when installing the integrated device 1000, but will refer to the "television image" after installation.

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

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

In the explanation of FIG. 12, step A3 is performed and then step A4 is performed, but steps A3 and A4 may be performed at the same time as long as the current is within the range of the rated current of the cigar plug cord. This makes it possible to shorten the time until the second control unit 200 is activated.

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

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

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

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