PROBLEM TO BE SOLVED: To provide a system which is convenient even for a user who does not have the manager authority of an operating system in the case of executing the viewer application of a drive recorder.SOLUTION: A user selects a card reader to be given an authority from a list of card readers displayed in a pulldown menu by clicking the acquisition button of a device name selection part, and then selects a drive in a drive selection dialog to be displayed by clicking the selection button, and clicks an authority application button. Then, a personal computer rewrites a registry such that the combination of the card reader selected by the user and a drive is given an authority. When an SD card of a drive recorder is read by a viewer application, the manger authority of an operating system in reading by the card reader is controlled not to be requested by referring to the registry.SELECTED DRAWING: Figure 9

Description

  The present invention relates to a system, a program, and the like.

  For example, a drive recorder that records vehicle status information (for example, forward video, speed, acceleration, etc.), which is information acquired by a vehicle, on a recording medium is a transport vehicle such as a truck, or a business vehicle such as a taxi or a bus. In addition, it is being installed in ordinary vehicles.

  Some drive recorders, for example, always record vehicle status information when the vehicle is running, and others record vehicle status information for a certain period of time before and after the occurrence of an accident or sudden braking.

  The recording of vehicle status information by such a drive recorder is performed on a removable recording medium such as a memory card such as an SD card which can be attached to and detached from the drive recorder. In many cases, analysis of vehicle status information is generally performed by processing of viewer application software (hereinafter referred to as a viewer application) that operates on a personal computer.

  At the time of analysis, this recording medium is extracted from the drive recorder of the vehicle, and this recording medium is inserted into a memory card reader connected to a personal computer for analysis such as an office. In the personal computer, the vehicle status information of the recording medium inserted in the memory card reader is read by the processing of the viewer application, and the information is visualized and displayed on the screen (for example, Patent Document 1). Thereby, confirmation and analysis of vehicle status information can be performed based on the information visualized on the screen.

JP2011-114850A

  Incidentally, there are various recording formats for recording on a recording medium readable by a personal computer. For example, a recording format that can be read by a standard function of a personal computer operating system and a recording format that cannot be read by a standard function of a personal computer operating system, but can be read by executing a dedicated reading program in the operating system. There is something. For example, Microsoft's Windows (registered trademark; the same shall apply hereinafter) supports standard formats for recording formats such as FAT and NTFS (hereinafter also referred to as file system), but for example, recording formats such as ext4. Is not supported by the standard.

  As a recording format of a recording medium recorded by the drive recorder, recording is generally performed in a recording format that can be read by a standard function by an operating system in which a viewer application operates. For example, if the operating system on which the viewer application operates is Windows, a type of FAT file system (for example, FAT32) which is a standard format that can be read by various devices is used.

  However, in a configuration in which the drive recorder records information on a recording medium in a recording format that the operating system can read with standard functions, files recorded by the file management software of the operating system itself can be deleted, or Other software that operates can easily read and rewrite information recorded by the drive recorder.

  Therefore, when there is a request to prevent such rewriting using other software for information recorded by the drive recorder such as vehicle status information, a recording medium that cannot be read by the standard function of the operating system is recorded. It is possible to adopt a configuration in which the information of the drive recorder such as the vehicle status information is stored by adopting it in all or part of the recording area.

  However, some recording media including a recording format area that cannot be read by the standard function of the operating system require the administrator authority of the operating system in order to read it by the security function of the operating system. In such a case, when the user of the viewer application is a user who does not have such administrator authority of the operating system, the information recorded by the drive recorder such as vehicle status information is read by the viewer application and visualized. I found a problem that I could not.

  Therefore, an object of the present invention is to solve such problems and to provide a system, a program, and the like that are easy to use even for users who do not have administrator authority, which is predetermined authority in the operating system.

(1) When operating an application program having a function of reading information stored by the drive recorder in a predetermined area that is not supported by the standard function of the operating system, a request for administrator authority is displayed by the operating system. It is good to set it as the system provided with the function for making it control so that it may not.

  This makes it difficult to rewrite information recorded by the drive recorder, and requests for operating system administrator authority during the operation of an application program having a function of reading the information recorded by the drive recorder. Even if the user is a user (for example, a general user) without the administrator authority of the operating system, the information recorded by the drive recorder can be read and used by this application program.

  For example, the predetermined area that is not supported by the standard function of the operating system may be a recording format area that is not supported by the standard function of the operating system.

  As the operation, for example, the application program may be in operation, and in particular, a process for the application program to read information stored by the drive recorder in a predetermined area that is not supported by the standard function of the operating system. It is good to prepare for this. For example, the operation of the application program may be configured to include access to other programs other than the operation of the application program. Desirably, the operating system may be configured not to display a request for administrator authority of the operating system only when accessing the application program.

  The operating system administrator authority may be an authority required to read information stored by the drive recorder in a predetermined area where reading is not supported.

  When operating an application program that has a function to read information stored by the drive recorder in a predetermined area that is not supported by the standard function of the operating system, do not display the administrator authority request by the operating system. It is preferable that the system has a function for controlling and reading information stored in the drive recorder in a predetermined area that is not supported by the standard function of the operating system.

(2) The predetermined area that is not supported for reading by the standard function of the operating system is a predetermined area in the recording medium, and a function for controlling the operating system not to display a request for administrator authority is It is preferable to provide a function of controlling so as not to display a request for the administrator authority of the operating system at the time of reading with the reading device.

  In this way, for the recording medium recorded by the drive recorder, the administrator authority of the operating system is not required for reading by the specific reading device, and reading devices other than the specific reading device are required. Now you can maintain the operating system administrator rights. For example, when the operating system as a whole is controlled so that the operating system does not request the administrator authority when reading from such a recording medium, the administrator authority is widely unnecessary. On the other hand, if the configuration is such that the operating system does not request administrator authority for each recording medium, it must be set not to request administrator authority for each medium. Every time the number of media increases, it becomes necessary to request permission to be granted. According to this configuration, such a problem can be solved. In particular, it may be configured to control to display the request for the administrator authority of the operating system when reading by a reading device other than a specific reading device.

  The recording medium may be a portable medium between, for example, a drive recorder and a computer having this system. For example, a USB memory or the like may be used, but in particular, a card-type recording medium may be used, for example, an SD card or the like.

The reading device is preferably a card reader, for example. In this way, only when the recording medium is read by a specific card reader, the general user can browse the information by the application program.
The reading device may be a reading device configured to be detachable from a computer including this system. For example, a USB-connected card reader may be used.

  It is preferable that a plurality of readers be configured to be detachable from a computer equipped with this system, and the administrator authority of the operating system is used when reading with a specific reader among such a plurality of readers. It may be controlled not to display the request. In addition, for example, in the case where the reading device includes a device incorporated in a computer equipped with this system and an external device, it is preferable to provide a function of making the built-in device a specific reading device. In this way, it is possible to reduce the possibility that a malicious third party or the like can read without an administrator authority by the external reading device.

  Whether or not it is a specific reading device may be determined based on, for example, identification information of the type of the reading device, identification information of the individual reading device, and the like. It is preferable to use identification information that can be acquired by the computer of the system and the operating system. For example, if the card reader is a USB connection and the operating system is Windows 8, it is necessary for each type of card reader (or for example, required by the operating system). Since the card reader can be identified for each type of device driver to be used), the identification information of the type of the reading device may be used.

  However, with such a configuration, problems such as inability to identify individual individuals among readers identified as the same type may occur. Therefore, for example, the reading apparatus physically connected to the computer on which the operating system is executed is controlled so as not to display the request for the administrator authority of the operating system when reading with a specific reading apparatus. Although it is good to set it as the structure performed based on the physical identification information of the reader for identifying this, it is especially good as follows.

(3) When reading with the specific reading device, control to prevent the display of the administrator authority request of the operating system is performed by reading physically connected to the computer on which the operating system is executed. It is preferable to provide a function to be performed based on both physical identification information of the reading device for identifying the device and logical identification information recognized and assigned by the operating system.

  In this way, for example, when a plurality of devices having the same physical identification information of the reading device are connected, the individual of the reading device that does not display the administrator authority request more reliably is identified, When reading with the reading device, the administrator authority request for the operating system is not displayed, and the physical identification information of the reading device is the same individual but the administrator authority request is not displayed. It is possible to identify an individual that is not a target and to display a request for administrator authority of the operating system when the individual is read.

For example, a drive letter may be used as logical identification information in which an operating system is assigned to the reading device. In this way, even if it is difficult to identify an individual using only the identification information possessed by the reading device, it is possible to more reliably determine whether the reading device is given the administrator authority. It becomes like this.
(4) It is good to provide the function for making a user select the said specific reading apparatus from the several reading apparatuses connected to the computer which has the said system.

  In this way, the user can determine a reading device to be controlled so as not to display a request for administrator authority of the operating system from among a plurality of reading devices connected to the computer. The reading device that is not selected by the user may be configured not to be the specific reading device.

  As a function for allowing the user to select the specific reading device from a plurality of reading devices connected to the computer having the system, for example, a plurality of reading devices connected to the computer having the system are identified. Information is acquired from the reading device and displayed in a list or the like, and the reading device selected by the detected user operation is selected as a specific reading device from the display of the list or the like It is good to have the function to judge as a thing.

(5) The function for controlling the operating system so as not to request administrator authority rewrites information in an information area used to determine whether or not the operating system requests administrator authority. It should be a function.

  This makes it easy to develop a program that the operating system executes with administrator privileges, such as developing a device driver for the operating system, without adding processing that prevents the administrator privilege from being requested. it can.

  The information in the information area used for determining whether or not the operating system makes a request for administrator authority may be rewritten to information that controls the operating system not to make a request for administrator authority. For example, Microsoft Windows 8 may be a function for rewriting registry area information used to determine whether or not to request administrator authority.

(6) The information area used for determining whether or not the operating system makes a request for administrator authority may be an area that is not erased even when the operating system is shut down.

  In this way, the administrator authority request is not displayed only by executing a program for rewriting the information area once. Thereafter, for example, prior to the execution of the application program, there is no need to re-execute the program for rewriting the information area one by one.

(7) The function of rewriting the information area used to determine whether or not the operating system requests administrator authority is a function executed before the function of reading the information recorded by the drive recorder It is good to have.

  In this case, the administrator authority is required when executing the function of reading the information recorded by the drive recorder, and it becomes necessary to call a person in charge with the operating system administrator authority. When the information recorded by the drive recorder is about to be read, it is possible to prevent the problem that the function of immediately reading the information recorded by the drive recorder cannot be realized.

  A configuration in which the function of rewriting an information area used to determine whether or not the operating system makes a request for administrator authority is a function executed before the function of reading information recorded by the drive recorder For example, when preparing for operation of an application program having a function of reading information stored by the drive recorder in a predetermined area that is not supported by the standard function of the operating system, the state of the storage area is changed. First, confirm that if the administrator authority is required, to determine whether the operating system requests the administrator authority before the function of reading the information recorded by the drive recorder A process of rewriting the information area to be used may be performed. The preparation for the operation may be, for example, when the application program is started for the first time, but particularly when the application program is installed.

  In addition, the operating system is a separate application program that has a function of reading information stored by the drive recorder in a predetermined area that is not supported by the standard function of the operating system. Configure a setting application program (hereinafter referred to as a setting application) having a function of rewriting an information area used to determine whether or not to request administrator authority, execute the setting application first, It may be configured to execute the information reading application.

(8) A program for causing a computer to realize a function of rewriting an information area used for determining whether or not the operating system makes a request for administrator authority, and a function of reading information recorded by the drive recorder It is recommended that the application program provided with is configured as another executable file.

  In this way, the computer can realize the function of rewriting the information area used to determine whether or not the operating system requests the administrator authority only for the computer that does not want to request the administrator authority. The program can be easily executed, and the program can be prevented from being introduced to a computer that desires the administrator authority, which increases safety.

(9) The function of reading the information recorded by the drive recorder by the operation of the computer by the application program requires a viewing authority for the information recorded by the drive recorder different from the administrator authority of the operating system; Good.

  The administrator authority of the computer operating system is usually given to the administrator of the computer. On the other hand, the present inventors have found that the authority to view information recorded by the drive recorder is not necessarily granted to the computer administrator. Therefore, a function for requesting the right to view information recorded by the drive recorder, which is different from the administrator authority of the computer operating system, is provided in the function for reading the information recorded by the drive recorder, thereby specifying both as different persons. Can be easily realized.

(10) When operating an application program having a function of reading information stored by the drive recorder in a predetermined area that is not supported by the standard function of the operating system, the operating system requests the administrator authority of the operating system. It is preferable to provide a function for invalidating a function for controlling not to perform display.

  In this way, the operating system administrator authority request can be displayed by the operating system. For example, the operating system administrator authority request display may not be performed by the operating system, and the original administrator authority request display may be restored later.

  For example, a function for controlling the operating system not to request administrator authority is a function for rewriting information in an information area used to determine whether or not the operating system requests administrator authority. In a certain configuration, information in the information area used to determine whether or not the operating system makes a request for administrator rights is rewritten to information that controls the operating system not to make a request for administrator rights. In such a case, it is preferable to provide a function for making this information information for requesting administrator authority.

(11) When operating an application program having a function of determining the version of the operating system system and reading the information stored by the drive recorder in a predetermined area that is not supported by the standard function of the operating system. When the operating system administrator authority request display is not performed by the operating system, it may be configured not to perform control so that the operating system administrator authority request display is not performed by the operating system.

In particular, due to recent security enhancements in the operating system, there are cases in which administrator privileges are not required in previous versions of operating systems, but administrator privileges are required in newer versions of operating systems. I found out.
(12) For example, it may be configured as a program for causing a computer to realize the functions described in (1) to (11) above.

  According to the present invention, it is possible to provide a user-friendly system, program, and the like even for a user who does not have administrator authority, which is predetermined authority in the operating system.

  Hereinafter, as an embodiment of the present invention, the present system will be described based on an example in which the system is realized by processing of a personal computer and a program executed on the personal computer.

As shown in FIG. 1, the SD card which is mounted on the drive recorder 1 and on which the vehicle status information is recorded by the drive recorder 1 is extracted from the drive recorder 1 and mounted on the SD card reader / writer 36 connected to the personal computer 35. In this state, the configuration performed by the personal computer 35 is an example of the present system.
On the personal computer 35, Windows 8 is operating as an operating system.

  The SD card is a card with a capacity of 16 GB, and the first 1 GB is a partition of FAT32 (hereinafter referred to as the first format) supported by the standard function of the Windows 8 operating system operating on the personal computer 35 (hereinafter referred to as the first partition). The remaining 15 GB is a partition (hereinafter referred to as a second partition) of a format (referred to as a second format) that is not supported by a standard function that is neither FAT32 nor NTFS but is supported by the drive recorder 1.

  In the first format area of the first partition, for example, as shown in the display example of FIG. 5, an installer file including an execution file of a viewer application which is an application program for displaying vehicle status information on the monitor of the personal computer 35 Is recorded. As information for identifying that the SD card is for this system, the volume label of the first partition is recorded as “DRIVEREC1”.

  As shown in FIG. 2, the drive recorder 1 attaches a mounting member such as a double-sided tape to the windshield at a position on the front passenger seat side adjacent to the rear-view mirror 4 near the center in the left-right direction above the windshield 3 of the vehicle. Attached and fixed. The drive recorder 1 is fixed with a camera lens facing in the direction of photographing the front of the vehicle. The drive recorder 1 is connected to the cigar socket 5 and the power cable 6 and receives power from the vehicle side when the accessory power supply of the vehicle is on.

  FIG. 3 is a diagram showing a schematic electrical configuration of the drive recorder 1. As shown in FIG. 3, the drive recorder 1 includes a controller MC, a CCD camera 13, an interface 33, a GPS receiver 24, an SD card reader 31, an acceleration sensor 15, a database 32, and the like. The controller MC is connected to the CCD camera 13 and converts an image signal from the CCD camera 13 into a digital signal that can be input to the controller MC, an acceleration sensor 15, a GPS receiver 24, an SD card reader 31, a database. 32 are connected to each other.

  The controller MC includes a known CPU, a memory such as a ROM and a RAM, a microcomputer, a microcomputer having other peripheral circuits, and the like. In the ROM of the controller MC, a GPS information processing program for storing GPS information received by the GPS receiver 24 in an SD card, a video processing program for storing video captured by the CCD camera 13 in the SD card, and an acceleration sensor 15 Various programs such as an acceleration recording program for storing the detected acceleration information over time in an SD card and an OS (Operation System) are stored, and the controller MC executes these programs to realize various functions.

  The GPS receiver 24 detects the position information of the own vehicle at the current time based on an instruction from the controller MC. In this embodiment, the detection timing is every second. The controller MC performs a position history recording process for storing a history of position information (hereinafter referred to as position history data) in the SD card via the SD card reader 31 every second. The position information is the time obtained based on the signal from the GPS satellite, the position of the vehicle, the speed, the latitude, the longitude, the altitude, and the like. Based on the signal from the GPS satellite, processing for recording the history of these various data is performed. The acceleration sensor 15 is a three-axis type sensor that detects acceleration and inclination in the directions of the three axes (X, Y, Z), and always outputs a detection value to the controller MC. The controller MC associates the information on the acceleration of these three axes with the time information every 10 ms, and stores it in the SD card via the SD card reader 31 as an acceleration information history (hereinafter referred to as acceleration history data). Process. The SD card reader 31 reads data of the SD card inserted from the insertion slot 18 or updates the data of the SD card based on the control of the controller MC. The database 32 is a nonvolatile memory (for example, EEPROM) externally attached to the controller MC. The CCD camera 13 outputs video information that is always taken via the interface unit 33 that performs digital conversion to the controller MC. The controller MC performs a constant recording process in which the video information input via the interface unit 33 is stored in the SD card via the SD card reader 31 as video information associated with time (hereinafter referred to as constantly recorded video data). In addition, the video information is temporarily stored in the memory (video for 20 seconds in this embodiment), and when the acceleration detected from the acceleration sensor 15 corresponds to the acceleration corresponding to the impact at the time of the accident, Data (event recording video data) that associates video information obtained by connecting video information temporarily stored for 20 seconds with video information for 20 seconds after the occurrence of an impact, and information on the time, via the SD card reader 31. Event recording processing to be stored in the SD card is performed.

  By these processes by the drive recorder 1, position history data, acceleration history data, constantly recorded video data, and event recorded video data are stored in the second formatted area of the second partition in the SD card. Record.

  The personal computer 35 is a general notebook personal computer on which Windows 8 operates, and FIG. 4 is a schematic configuration diagram illustrating a part of the personal computer 35 and devices connected to the personal computer 35. As shown in FIG. 4, the personal computer 35 includes an MPU (Micro Processing Unit) 37 that is a control device. A ROM 38 and a RAM 39 are connected to the MPU 37. A hard disk drive 40, a keyboard 42, a touch pad (not shown), and a monitor 45 are connected to the MPU 37 via corresponding interfaces (not shown). A mouse 43, a printer 44, and an SD card reader / writer 36 are connected to a USB port of the personal computer 35. The hard disk in the hard disk drive 40 stores Windows 8 (programs and data constituting the operating system) that is an operating system of the personal computer 35 and various application programs and data that operate on Windows 8.

  The user can start various programs using functions of the operating system, such as double-clicking an application program startup icon by operating the touchpad or mouse 43 (hereinafter referred to as a pointing device). The personal computer 35 can execute processing by the application program, and the personal computer 35 can realize a predetermined function. Hereinafter, the mouse 43 is clicked, the touch pad is tapped, the enter key of the keyboard 42 is pressed, and the like.

The user removes the SD card in which data is recorded by the drive recorder 1 from the drive recorder 1 and attaches it to the SD card reader / writer 36 connected to the personal computer 35.
The operating system of the personal computer 35 accesses the SD card via the USB port by attaching the SD card to the SD card reader / writer 36.

  The operating system recognizes the first partition of the first format supported by the standard functions in the SD card and displays a list of files within it. As a result, the viewer application installer file is displayed in the list. If the viewer application has not yet been installed, the user causes the operating system to execute this installer file by double-clicking the pointing device with a pointing device. When the installation is completed, an application for executing the viewer application is displayed in the operating system.

  When the installation of the viewer application is completed or has already been installed, the user can start the viewer application by double-clicking the icon of the viewer application displayed on the desktop of the monitor 45 by the operating system. The operating system detects such a viewer application activation operation and activates the viewer application.

  When the viewer application is activated, a folder reference dialog similar to that shown in FIG. 10 is displayed. The user selects a drive corresponding to the drive in which the SD card is inserted among these drives recognized by the displayed operating system. Here, it is assumed that the drive with the drive letter “i:” displayed as “DRIVEREC1” as the volume label is the drive into which the SD card is inserted. If the user selects a selection by clicking on the “DRIVEREC1 i:” pointing device and the click on the “OK” button is detected, the viewer app stores it in the second partition of the drive with drive letter “i:” The operating system is requested to access the recorded event recorded video data. The operating system receives this request from the viewer app process and attempts to access the event recording video data stored in the second partition, but determines that the second partition is in a format not supported by the standard. Therefore, the information in the registry area used to determine whether or not to request administrator authority prepared for each device of the card reader of this drive should not request administrator authority. If the value is not to prevent the request for administrator privileges, whether the user account currently logged in to this operating system has administrator privileges Determine whether. If the user account does not have administrator authority, information indicating that the administrator authority is required is returned to the viewer application. The viewer application requests the operating system to display an administrator authority request dialog of the operating system as shown in FIG. On the other hand, when the user account has administrator authority, access to the second partition area for the viewer application is permitted.

  The administrator authority request dialog is a dialog requesting the user to input the user name and password of the administrator account. Here, if the user name and password of the administrator account are entered by the viewer application user and a click on "Yes" is detected, the operating system will combine the entered user name and password. Determines whether it matches the one registered in the operating system as the administrator account. If they match, access to the second partition area for the viewer application is permitted, whereas if they do not match, access to the second partition area for the viewer application is not permitted.

  The viewer application determines whether or not access permission to the second partition area is obtained from the operating system system. If access permission is not obtained, an error dialog similar to that shown in FIG. 11 is displayed. Is displayed, and the click on “OK” or the like is detected, the viewer application is terminated. Thus, unless the user name and password of the administrator account are input, the data stored in the second partition area cannot be displayed by the viewer application.

  Note that the information in the registry area used to determine whether or not to request administrator authority prepared for each device of the card reader of the drive described above does not request administrator authority. In determining whether or not it is a value to be, the information of the registry area used to determine whether or not to request administrator authority prepared for each device of the card reader of this drive, If the value is set so as not to request administrator rights, it is not determined whether the user account currently logged in to this operating system has administrator rights. Information indicating that the administrator authority is required for the viewer application is not returned. As a result, access permission can be obtained even for a user without administrator authority, and the operation of this application can be continued.

  The viewer application includes a program for accessing the area of the second format. This program may be configured to access an area of its own format, but it is not supported by the Windows standard, but access to a file system in a format that is supported by other existing operating systems. A program for this purpose may be incorporated.

  When the access permission is obtained, the viewer application accesses the data stored in the second partition area by using a program for accessing the file system of the second format owned by the viewer application. The position history data, acceleration history data, constantly recorded video data, and event recorded video data recorded by the drive recorder 1 are read in the second formatted area of the second partition in the SD card. Process to display in.

  FIG. 5 is an example of a viewer screen displayed on the monitor 45 by this processing. A menu bar 52 for executing various operations is arranged at an upper position of the viewer screen 51. In the lower left direction of the menu bar 52, in the order from the top, the video display area 53 for displaying either the continuously recorded video data or the event recorded video data stored in the SD card, and the speed in the position history data. Travel speed display area 55 for reproducing and displaying information, acceleration display area 56 for reproducing and displaying acceleration information in acceleration history data, latitude / longitude display area 57 for reproducing and displaying latitude / longitude information in position history data, acceleration Video drive button on the history display area 59 in order from left to right, video rewind, cue, reverse playback, pause, playback, last forward, fast forward buttons, 20 seconds before and after the playback time of acceleration history data An acceleration history display area 59 for reproducing and displaying the three-axis accelerations in a line graph is arranged. Playlist 60 in order from the top to the right under the direction of over 52, are disposed a map area 61. It should be noted that the reproduction display of any area is reproduced and displayed in synchronization with the same time information included in each data (hereinafter, reproduction of these information in synchronization is referred to as synchronous reproduction).

  The play list 60 displays a list of event recording video data. Since this list is recorded as a group of event record video data (40 seconds before and after the occurrence of an impact in this embodiment) (hereinafter referred to as an event unit), the start time for each group (in the event unit) Display information. Each unit displaying the time information is a button, and the user views the time of each event displayed in the play list 60 and clicks the button of the event to be reproduced.

  By the processing, the viewer application starts synchronous playback for the event clicked by the user. The first image displayed at this time is a still image of the event recorded video data at the time when it is determined that an event has occurred. The captured image is reproduced by detecting the operation of the video drive button, and with the reproduction, the traveling speed display area 55, the acceleration display area 56, and the latitude / longitude display area 57 each have time data corresponding to the image. In the map area 61, a surrounding map including the point where the image was taken at that time is displayed. The acceleration history display area 59 displays the acceleration history in the three-axis direction of the photographed image over the stored time (total 40 seconds), and the acceleration position at the time currently displayed in the video display area 53 is displayed vertically. Plotted as a bar.

The user can display a still image in the video display area 53 at an arbitrary position for 40 seconds of the captured image of the file by operating the video drive button, and can further display a moving image in 40 seconds. it can. When a moving image is displayed, the display of the traveling speed display area 55, the acceleration display area 56, the latitude / longitude display area 57, the acceleration history display area 59, and the map area 61 also changes in synchronization with the movement. When pressing of the “Close” button under the playlist 52 is detected, the video display area 53 is switched to a state in which the recorded video data is always displayed, and playback is performed from an arbitrary position by operating the video drive button. It also has a function to do.
As described above, in the state having the administrator authority, the data recorded in the drive recorder 1 can be reproduced and displayed on the SD card.

  However, as described above, if you start the viewer application without logging in to the operating system with an account that has administrator privileges, an administrator privilege request dialog is usually displayed, prompting you to enter the administrator account username and password. It is done.

  For example, in a company organization, the administrator authority of the operating system of a personal computer is only a specific person who is given authority as a so-called system administrator, and the viewer application user does not have administrator authority. .

  In order to prevent users from requesting administrator rights one by one, the system administrator, for example, executes the authority change application described below before installing the viewer application described above, and accesses the second partition by the viewer application. In this case, the administrator authority request dialog can be prevented from being displayed.

  The authority change application is stored in the USB memory and distributed to the system administrator. The system administrator inserts this USB memory into the USB port of the personal computer 35. The operating system recognizes the USB memory and displays an icon for starting the authority change application on the monitor 45.

The system administrator activates an authority change application (an application program executed on the operating system) by double-clicking the icon.
The operation of the authority change application will be described with reference to FIGS.

  FIG. 7 is a confirmation screen that is displayed first when the authority change application is executed. On this confirmation screen, the user who does not have administrator authority is given an authority that allows the viewer application to display data, and the system administrator has the operating system administrator authority. It needs to be executed, there is a possibility that it may affect other software, and it is desirable to know the information of the devices connected to this personal computer (not shown, especially for example SD card reader / writer) Along with the display of text information indicating each of the disclaimers, and the display of text information indicating the contents of the operation instructions indicating whether or not to agree Under the display of the text information, an “I agree” button and an “I don't agree” button are displayed.

  When the user (the user of this application is a system administrator) detects the click of the “agree” button or the like by the operation of the pointing device, the selection of the device and the drive whose authority is changed as shown in FIG. Displays the main screen for accepting authorization and initialization operations. The main screen includes a device name selection unit including a text display of “device name” in FIG. 8, a pull-down menu provided on the right side thereof, an acquisition button displayed on the right side thereof, and “drive name” below the device. Text display, a selected drive display section labeled “Please select a drive” in FIG. 8, a drive name selection section with a selection button displayed on the right side of “Select”, and a left side below that In order toward the right side, the window includes an initial value return button that displays “return to initial value”, an authority button that displays “grant authority”, and an end button that displays “end”.

The user first clicks the acquisition button in the device name selection section, selects the target card reader to which authority is granted from the list of card readers displayed in the pull-down menu, and then displays the information by clicking the selection button. When a drive is selected in the drive selection dialog and a right grant button is clicked, the right is given to the selected combination of card reader and drive. On the other hand, when the initial value return button is clicked, the authority given to the selected combination of the card reader and the drive is lost, and the combination returns to the state where the authority is requested. You can also end this application by clicking the end button.
More specific processing by this application will be described.

  When the user clicks on the acquisition button shown in FIG. 8 or the like is detected, the operating system is requested to acquire a list of card reader / writers connected to the personal computer 35, and this list is received and entered as a list in a pull-down menu. (See FIG. 9). As a result, the user can select a specific card reader from the pull-down menu list. When a specific card reader is selected, the content of the text display that is displayed when the pull-down menu is not pulled down is used to display the name of the selected card reader. For example, in FIG. 9, four types of card reader / writers (physically one but having four types of media slots and recognized by the operating system as four types of card reader / writers) are connected. This is an example of the case. Here, an example in which the card reader / writer “BUFFALO BSCR20TU3-CF / MD USB Device (disk drive, USBSTOR \ DiskBUFFALO_BSCR20TU3_-CF / MD1.00 \ dDevice \ 00000096)” is selected will be mainly described. When this card reader is selected, the text display of the device name in the pull-down menu in FIG. 8 that is not pulled down is “BUFFALO BSCR20TU3 -CF / MD USB Device dDevice \ 00000096) "is displayed up to the displayable range within the text display width.

  When the user clicks the selection button or the like, a drive selection dialog as shown in FIG. 10 is displayed. The drive selection dialog includes a text display for prompting selection of a drive whose authority is to be changed, a drive list display section for displaying a list of drives in the personal computer 35, an OK button, and a cancel button. If a click on the cancel button is detected, the screen returns to the main screen. A system administrator who is a user selects a drive to which authority is given. For example, the user can easily select an I drive having “DRIVEREC1” indicating that the volume label of the SD card is that of this system as a drive unrelated to the other system. . When one drive is selected from the drive list displayed in the drive list display section, the OK button can be clicked.

  When the click of the OK button or the like is detected, it is determined whether or not the selected drive is a valid drive. If the selected drive is not a valid drive, an error including text information indicating that the selected drive is not valid is shown in FIG. Displays a dialog. When the click of the OK button provided in the error dialog is detected, the display returns to the drive selection dialog shown in FIG. Whether or not the drive is valid is determined by inquiring from the operating system whether or not the drive selected in the drive selection dialog is a card reader drive. For example, when “BD-ROM drive (G :)” is selected, it is not a card reader drive, so an error dialog is displayed.

  On the other hand, if it is determined whether or not the selected drive is a valid drive, if it is a valid drive, the drive name of the drive selected in the drive selection dialog is displayed on the selected drive display unit in FIG. . Here, the case where “DRIVEREC1 i:” is selected will be mainly described. In this case, the display of the selected drive display section labeled “Please select a drive” in the state of FIG. 8 is changed to the display of “DRIVEREC1 i:” and is displayed.

  When the click of the authorization button or the like is detected, it is determined whether or not the currently selected device and drive are a valid device and drive combination. Whether or not the device is a valid device / drive combination is determined, for example, by querying the operating system to which drive the selected device is assigned, and whether the assigned drive matches the selected drive. Do by.

  If it is not a valid device / drive combination, the second error dialog shown in FIG. 12 is displayed. The second error dialog includes text information including content indicating that a valid device / drive combination is not selected, content indicating that a valid device / drive combination needs to be selected, and an OK button. Prepare. When the click of the OK button or the like is detected, the screen returns to the main screen.

  If the combination is a valid device and drive, an authorization confirmation dialog shown in FIG. 13 is displayed. In the authorization confirmation dialog, text information that asks if authorization should be granted, text information of the device name of the selected device, text information of the drive name of the selected drive, and “Yes” and “No” Agree / disagree button.

  If a click on the “No” button or the like is detected, the screen returns to the main screen. On the other hand, when a click on the “Yes” button or the like is detected, in order to determine whether or not to request administrator authority in accessing the selected card reader in the Windows registry area. The information in the registry area used for the above is rewritten to a value that prevents the request for administrator authority. Note that this rewriting requires administrator authority depending on the operating system, so if there is no administrator authority, the administrator authority request dialog shown in FIG. 6 is displayed to request administrator authority. It will be. When the rewriting is completed, an authority grant completion dialog as shown in FIG. 15 is displayed. As described above, when Windows accesses an area of the second format that is not supported by the standard, the registry area prepared for each device of the card reader in which the SD card in which the area is inserted is provided. Refers to the value to determine whether or not to request administrator authority, and if it is not a value that does not do so, the normal process to request administrator authority, but the value that does not do so In this case, the process for not performing the process of requesting the administrator authority is performed. Therefore, by rewriting the value of the registry area prepared for each device of the card reader to a value that does not request administrator rights, the viewer application can access the area of the second format. In addition, the administrator authority request dialog of the operating system shown in FIG. 6 can be prevented from being displayed.

  As shown in FIG. 15, the authorization completion dialog includes a text display indicating that the authorization has been given, a text display of content requesting reconnection once the SD card reader / writer 36 is removed from the personal computer 35, and “ OK button is provided. When the click of the OK button or the like is detected, the main screen is restored.

In this way, authority can be given to a specific card reader. To return to the state in which the granted authority is lost and the original authority is not granted, the device and drive pair whose authority is to be removed is selected by the same operation and process as the authorization process on the main screen of FIG. When a click on the return button, etc. is detected, the device and drive pair are confirmed to be correct by the same operation and process as the authorization process, and if it is correct, it is selected in the Windows registry area. The registry area information used to determine whether or not to request administrator authority when accessing the card reader is a value that does not request administrator authority (standard operating system) Value). Among the above-mentioned authority grant processes, the difference in the authority initialization process is that the text “Unauthorize the following devices” in the authorization confirmation dialog shown in FIG. The authority initialization confirmation dialog is changed to the text display "initialize authority", and the authority change completion dialog of FIG. 15 is displayed instead of the authority grant completion dialog of FIG. 14, and the other points are the same. It is processing of.
If a click on the end button on the main screen is detected, this application is terminated.
As described above, it is possible to eliminate or grant authority to a specific card reader.

  When the authority is granted as shown in the dialog of FIG. 13, the user clicks “DRIVEREC1 i:” with the pointing device in the folder browsing dialog in the processing when the viewer application is started as described above. If the viewer app clicks on the “OK” button, etc., and the viewer application requests the operating system to access the event recorded video data stored in the second partition of the drive with the drive letter “i:”, The operating system does not request administrator rights for information in the registry area used to determine whether to request administrator rights prepared for this card reader device on this drive. Log in to this operating system. It is not determined whether the current user account has administrator authority, and information indicating that the administrator authority is required is not returned to the viewer application with administrator authority. Even a user who does not have access permission can obtain access permission and continue the operation of the viewer application. Therefore, the position history data, acceleration history data, constantly recorded video data, and event recorded video recorded by the drive recorder 1 in the second formatted area of the second partition in the SD card of this drive Data can be read and each data can be visualized as shown in FIG.

  As described above, the authority changing application is operated when the viewer application having the function of reading the information stored by the drive recorder 1 for the second partition of the SD card that is not supported by the standard function of Windows 8 is used. Windows 8 can be controlled not to display a request for administrator authority of the operating system. Therefore, it is difficult to rewrite the data recorded in the second partition by the drive recorder, and the operating system administrator authority is required during the operation of the viewer app having the function of reading the information recorded by the drive recorder. The request display is not performed, and the user who is a standard user of the operating system can also read and use the data recorded by the drive recorder by this application program from the display as shown in FIG.

  Since the processing shown in FIG. 8 and subsequent figures has a function of controlling the display of the administrator authority request of the operating system when reading with a specific card reader, the SD card recorded by the drive recorder 1 is provided. When reading with this card reader, the administrator authority of the operating system is no longer necessary, and the reading apparatus other than this card reader can maintain a state that requires the administrator authority of the operating system. For example, when the entire operating system is read from such a recording medium, if the operating system is controlled not to request the administrator authority, the administrator authority is widely unnecessary and the SD is not required. If it is configured to control the card so that it does not request administrator authority for each card, it must be set not to request administrator authority for each SD card. The viewer app is not immediately available. Moreover, according to the present system, such a problem can be solved. Only when a SD card is read by a card reader selected in advance by a system administrator user, a standard Windows user can view the data of the second partition using the viewer application.

  Further, as shown in FIG. 13, control is performed so as not to display a request for administrator authority of the operating system at the time of reading with the selected card reader, but it is physically connected to the personal computer 35. And a function that is performed based on both a physical device for identifying the card reader and a drive that is logical identification information recognized and assigned by the operating system. Therefore, when a card reader with the same device name is connected, the individual card reader that does not display the administrator authority request is identified more reliably, and the operating system is managed when reading with that card reader. To identify the card reader of an individual who is the same individual as the card reader and whose device name is not subject to the administrator authority request display. It is possible to display a request for administrator authority of the operating system when the individual card reader reads.

  As shown in FIG. 8, when the main screen is in the initial state, the pull-down menu does not acquire the list in advance and display it in the initial state, but the pull-down menu is displayed as blank and the acquisition button is clicked, etc. The list is acquired and displayed. By doing so, it is possible to make the system administrator aware of connecting or confirming a card reader to which authority is granted.

  In addition, since a function for allowing the user to select a specific card reader from a plurality of card readers connected to the personal computer 35 is provided, the system administrator user can select a plurality of card readers connected to the personal computer 35. It is possible to determine a card reader to be controlled so as not to display the request for administrator authority of Windows 8 from the inside.

  In addition, since the registry area information used for determining whether or not Windows 8 makes a request for administrator authority is rewritten, a program that the operating system executes with administrator authority, such as developing a Windows 8 device driver, is used. It can be easily implemented without adding processing to prevent the administrator authority request operation.

Further, since the registry area is recorded on a non-volatile recording medium such as a hard disk, it is not erased even when the operating system is shut down. Therefore, the administrator authority request is not displayed only by executing the authority changing application once and rewriting the registry area. Therefore, for example, prior to the execution of the viewer application, there is no need to re-execute the authority change application again and again.
The authority change application may have a function that is executed prior to the execution of the viewer application.

It may be configured to add a function for executing the authority change application to the viewer application installer. In this way, when you try to view the data recorded by the drive recorder with the viewer app, such as requiring administrator privileges when you run the viewer app, you will need to call the system administrator. The problem of not being able to see immediately can be prevented.

  In this embodiment, the authority change application and the viewer application are configured as separate execution files. Therefore, the system administrator can easily execute the authority change application only for a personal computer that does not want to request administrator authority. In addition, it is easy to not execute the authority change application on the computer that wants to request the administrator authority, which increases the safety.

The viewer application may have a function that allows only the operation manager provided in the organization separately from the system administrator to view the data in the second partition area. For example, immediately after starting the execution of the viewer application, a screen for entering the operation manager ID and password is displayed, and the user is given the operation manager ID and password, and the operation manager ID and password registered in advance are displayed. If they match, the process may be shifted to a process for displaying a folder reference dialog similar to that shown in FIG. In this way, the system administrator and the operation manager can be easily specified by the organization as different persons and operated. The operation manager may be, for example, a person who manages the vehicle on which the drive recorder 1 is installed or a person who manages the driver of the vehicle.
Since the authority change application has a function for initializing the granted authority, the administrator authority request can be displayed.

  The authority change application may be configured so that the Windows version is determined, and if the version is a version that does not display the request for administrator authority, the registry is not rewritten as described above. In Windows XP, this process is not necessary.

  As an embodiment of the present invention, the present system has been described based on an example realized by a personal computer and a program executed on the personal computer. For example, when the system is configured as a program that operates on a terminal on which a multi-user operating system operates. Good. For example, it may be configured as a program that operates on an operating system used for a tablet or the like.

  The drive recorder 1 is configured to include a camera that captures the front of the vehicle, but may be configured not to include a camera, for example. Further, when a camera is provided, the shooting location is not the front, but may be the rear or side and a combination thereof. Further, the shooting location may be inside the vehicle instead of outside the vehicle, or both inside and outside the vehicle may be taken. However, it is particularly preferable to have a function of photographing the inside of the vehicle. Thus, the effect which is excellent in the structure which acquires vehicle condition information in order to manage a driver is exhibited.

  In this embodiment, when the user account does not have the administrator authority, the configuration for displaying the administrator authority request dialog of the operating system as shown in FIG. 6 has been described. Is such an administrator authority request necessary? If the administrator authority request is required by acquiring from the operating system, the administrator authority is also unnecessary for the configuration in which the processing of the application is terminated so that the processing of the application is terminated or interrupted. Demonstrate the effect.

  When the initial value return button or the like is clicked, all the authority that has already been given authority is lost, and it may be configured to return to a state where no authority changing application is executed.

  The setting data of the drive recorder 1 may be recorded in the second partition area. For example, when the click of the gear-shaped icon at the right end of the menu bar 52 of the viewer application in FIG. 5 is detected, the operation setting screen of the drive recorder 1 is displayed as shown in FIG. 16, and the OK button is clicked. Or the like is detected, the setting contents of the setting items on this screen may be stored as setting data of the drive recorder 1 in the second partition area. The drive recorder 1 reads the setting data stored in the second partition when the power is turned on, and performs the processing with the content of each setting item referred to in the processing of the drive recorder 1 as that of the setting content. In this way, the setting data can be prevented from being falsified, and the setting data can be easily viewed or changed even by a user without administrator authority.

The present invention is not limited to the configurations described in the above-described embodiments. The components of the above-described embodiments can be arbitrarily selected and combined within a combinable range. In addition, the present invention can be configured in combination with any component within a range that can be combined with any component described in the means for solving the invention.
