When power supply from the DC jack is terminated, the operation log data imaging process shown in FIG. 6 is performed. In this process, the acceleration obtained from the acceleration sensor 25 recorded in the “operation record” folder provided in the memory card 14 by the operation log function, the current position obtained from the GPS receiver 8, the current time, and the speed (vehicle speed) The vehicle status data consisting of) is incorporated into the image data and the operation log data imaging function is recorded in the “DCIM” folder.
A flow of processing in which the control unit 18 realizes the operation log data imaging function will be described with reference to FIG.

  First, in step (hereinafter referred to as S) 110, it is determined whether or not there is a file in the operation record folder. If there is no file (S110: N), this process ends. This is because, for example, when the engine is started and immediately turned off, the operation is finished without executing the operation log data imaging function. If there is a file in the operation record folder (S110: Y), the process proceeds to S120.

  In S120, the operation log file of the current travel section is selected, and an image including the characteristic content of the operation log in the file is generated. As a characteristic content of the operation log, an image including a departure date / time, a departure place, an arrival date / time, and an arrival place is generated. For example, as shown in FIG. 7, the title “service log”, departure date and time “2010/01/10 10:30:25”, departure place “Nagoto-ku, Nagoya, Aichi Prefecture” and arrival date and time “2010/01/10 11: 25:13 ”, arrival location“ Toyota-cho, Toyota, Aichi Prefecture ”and the like, the font stored in the non-volatile memory is expanded and displayed. Below the title, a horizontal separator is drawn.

  The departure date and time is the date and time recorded in the first line of the operation log file, and the departure place is searched from the first line of the operation log file in order, and the latitude and longitude data acquired from the line where the current position data is first recorded The corresponding place name is specified and displayed based on the map data in the database 19. This is because the position information cannot be obtained from the GPS receiver 8 immediately after departure. The arrival date and time is the date and time recorded in the last line of the operation log file, and the arrival location is specified and displayed based on the map data in the database 19 corresponding to the latitude and longitude data acquired from the last line of the operation log file.

In subsequent S130, the image data displayed in S120 on the display unit 5 is encoded into an image file in JPEG format, and the operation log file of the current travel section is embedded in the encoded JPEG image file. Generate an embedded image file. This file is embedded in the implant JPEG format. That is, when the JPEG file is read and displayed by the viewer software for the JPEG file, the operation log file is embedded in a data area that does not affect the development and display of the image in the JPEG image format.
In subsequent S140, the embedded image file generated in S130 is moved into the “DCIM” folder and stored.

In the subsequent S150, the current operation data file is moved to the “image generated” folder, and the present process is terminated.
In this way, the image file stored in the “DCIM” folder is wirelessly transferred to the disk of the file storage service server set in advance by the personal computer.

  In this way, for the transferred data, the server address is entered in the browser of a personal computer connected to the Internet, the ID and password are entered, and the list is displayed as a thumbnail by accessing this server. can do. From the list of thumbnails displayed, select the file to be downloaded to your computer by checking the check box and download it.

Thus, when displayed as thumbnails, for example, as shown in FIG. 7, the departure date / time / departure location / arrival date / time / arrival location are displayed in the thumbnail image. You can check which data is selected by looking at the thumbnail of the image.
Download the checked file and store it in the “My Pictures” folder on your computer. For example, the file of FIG. 7 is stored.

  Then, by simply displaying the files in the “My Pictures” folder as thumbnails with your computer's filer (for example, Windows (registered trademark) Explorer, or Mac, the standard filer called Finder) You can see if the log is embedded inside.

  The personal computer stores a program for extracting the embedded file from the implant JPEG file. When this program is executed, a JPEG file selection screen is displayed, and a process of extracting a file embedded in the selected JPEG file and storing it in a folder (directory) selected as a new file is performed. Is called.

  For example, when the file in which the thumbnail image of FIG. 7 is displayed is selected, the operation file embedded in this file is extracted and stored in the “extracted operation data” folder designated by the user.

  As described above, the radar detector includes a flash memory 44 and can be connected to the memory card 14 having a function of transmitting a file in the JPEG file format among the files stored in the flash memory 44 by wireless communication. A memory card reader 13 to which the card 14 is connected; and a control unit 18 for controlling the flash memory 44 of the memory card 14 to store a file in the JPEG file format. The control unit 18 generates the radar detector. Information to be embedded in a JPEG file format file. For this reason, since the information generated by the radar detector is embedded in a file in the JPEG file format, the control unit 48 of the memory card 14 determines that the file is in the JPEG file format, and uses the wireless LAN module to wirelessly communicate the file. 46 will be transmitted. Therefore, even a radar detector that does not have a wireless communication function can transfer information generated by the radar detector to an information system such as a server or a personal computer by wireless communication.

  The memory card 14 is a memory card that is compatible with the SDHC memory card in terms of its electrical characteristics and structure, and the memory card reader 13 is for connecting a memory card of the SDHC memory card standard. Generates an image file as a file in the JPEG file format, generates operation log information not defined in the file format standard of the JPEG image file as information generated by the radar detector, and embeds it in the file in the JPEG file format In this configuration, the data is stored in the flash memory 44.

  In this way, a memory card 14 having a wireless LAN connection function can be connected instead of an ordinary SDHC memory card having a storage function. The JPEG file format is recorded as a file having an extension of “.JPG”. The video data is recorded as a file having an extension of “.MPG” in the MPEG format. Therefore, it can be reproduced and displayed as a still image or a moving image by the information system, and information generated by the radar detector contained in the file can be easily confirmed.

  Note that the memory card 14 is intended to transmit only files in the “DCIM” folder by wireless communication, and may have a function of deleting a file already transmitted by wireless communication from the storage means. The control unit 18 may store a JPEG file format file in the “DCIM” folder and store a file serving as a backup of the stored file in a folder other than the “DCIM” folder. For example, in S140 of FIG. 6, the embedded image file generated in S130 may be copied into the “backup” folder and then moved to the “DCIM” folder for storage. In this way, for example, the radar detector again processes the information generated by the radar detector embedded in the file deleted from the flash memory 44 in the memory card 14 by the control unit 48 of the memory card 14. When you try to use it, you can refer to the backup file in the “backup” folder and use it for processing. For example, when the engine is turned on next time, the contents of the previous operation log can be displayed. For example, when the engine on this time is the engine on after the operation shown in FIG. 7, the latest image stored in the “backup” folder is displayed on the display unit 5 for 20 seconds. Let By doing in this way, the acquisition situation of the last operation log can be confirmed again at the start of the next operation. Of course, the present invention is not limited to this and can be used for various processes. Further, for example, even if a recording medium storing a file acquired by wireless communication from the memory card 14 is lost or the file is deleted from the recording medium, an information system (including a memory card reader) For example, the memory card 14 is connected to a personal computer or the like, and the information generated by the radar detector can be acquired again from the “backup” folder of the memory card 14.

  Note that the backup file may be a file including information generated by the radar detector, and this file may be one file or a plurality of files. In addition, this file may be configured to be added to an existing file or may be configured to newly create a file.

  In addition, the above-described embedding may be performed when a JPEG file format file is stored in the “DCIM” folder, and a determination may be made as to whether to store a backup file in the “backup” folder. That is, it is not always necessary to create backup files corresponding to all JPEG file format files. For example, it is preferable to create a backup file only for necessary information generated by a radar detector. For example, when the radar detector detects an acceleration in the front-rear direction of 0.3 G or more, which is an acceleration corresponding to an impact at the time of collision, from the acceleration sensor 25, the screen of the display unit 5 is the same as the screen of FIG. "Precaution for sudden deceleration" is displayed in the title section, and a screen displaying the date and place where sudden deceleration was detected is displayed below, and a file in JPEG file format in which this information is embedded as a text file is generated Then, the file is stored in the “DCIM” folder and a backup file is created in the “backup” folder, while copying to the “backup” folder in S140 of FIG. 6 is not performed. Also good.

The JPEG file format file of this embodiment has a file format identification area for identifying whether or not it is a JPEG file format file, and the function of embedding information generated by this radar detector in a JPEG file format file is as follows. It is configured to embed in an implant JPEG format in which information (operation log information) generated by the radar detector is stored in an area other than the file format identification area. In addition, the memory card 14 with the extension “.JPG” is affected by the operation log information generated by the radar detector in order to identify whether the file is a JPEG file format by referring to the file format identification area. Instead, it is determined that the file is in the JPEG file format, and the JPEG file is transmitted by wireless communication. Therefore, even a radar detector that does not have a wireless communication function can transfer information generated by the radar detector by wireless communication.

  The JPEG file format is a file format for storing information that can be visualized, and the control unit 18 embeds log information generated by the radar detector in a JPEG file format file and visualizes the information generated by the radar detector. The information is generated as possible information. Therefore, the operation log information generated by the radar detector can be displayed as information that can be visualized by an information system such as a personal computer. For example, if you display an image of this JPEG file with an image viewer software such as a destination PC, the information generated by the radar detector is included in the image as information that can be visualized. The information generated by the radar detector contained in the file can be confirmed. For example, it is possible to easily check which file includes necessary information by displaying thumbnails or slideshows on a transfer destination personal computer or the like.

  In this embodiment, the information generated by the radar detector is generated as character string information as the information that can be visualized, but may be generated as a two-dimensional code. For example, together with the character string displayed as shown in FIG. 8, the contents of the character string may be displayed in a two-dimensional code and embedded in a JPEG file. In this way, for example, the character string information can be displayed as information that can be visualized by an information system such as a personal computer, and the information generated by the radar detector contained in the file can be confirmed by the character string. In addition, for example, it is possible to easily read at least a part of the information generated by the radar detector to the portable device or the like by reading the two-dimensional code with the portable device or the like.

  Moreover, in this embodiment, the display part 5 is provided and the control part 18 is set as the structure which produces | generates at least one part of the information displayed on the display part 5 as information which can be visualized. For this reason, at least a part of information displayed on the display unit 5 of the radar detector is displayed as visible information simply by opening the file with a viewer of an information system such as a personal computer. Further, for example, at least a part of information displayed on the display unit 5 of the radar detector can be displayed as visible information even in a terminal other than a personal computer such as a mobile phone or a digital camera. Therefore, the information displayed on the display unit 5 of the radar detector can be easily recalled by looking at the thumbnail display etc., and it is easy to determine when the recorded information is included on various devices. It becomes possible to specify.

  In this embodiment, the information that can be visualized is generated as information displayed in the same display mode as that displayed on the display unit 5 when the information that can be visualized is visualized. That is, the screen shot image displayed on the display unit 5 is generated as information that can be visualized.

  Further, the information generated by the electronic device is information that changes with the passage of time, and the predetermined file format is a moving image file format, and the information that changes with the passage of time as the information that can be visualized May be generated as the information that can be visualized in synchronization with the passage of time of the moving image file. For example, it is good also as a structure which displays the item recorded on an operation log file in the video data in embodiment shown and demonstrated to FIGS. For example, the longitudinal acceleration may be displayed in the video. In this way, it is possible to grasp the information generated by the electronic device at that time included in the file only by reproducing the moving image file with the information system.

  Further, the audible information may be stored in the video data. For example, the radar detector may further include a microphone, and the control unit 18 may capture the sound from the microphone and store it in the video data. The control unit 18 can embed the operation log information generated by the radar detector in the file format file of the video data, and can also read out the operation log information generated by the radar detector by voice synthesis and audible it in the video data. It is good to make it the structure which produces | generates as simple information. For example, when the acceleration exceeds a predetermined value, the acceleration is read out by voice synthesis and also generated as information that can be made audible in the video data. In this way, for example, it is possible to reproduce sound about acceleration in the video data generated by the radar detector as information that can be made audible by an information system such as a personal computer.

  In addition, operation log information may be embedded in a file in an audio file format as a file format for storing audible information, and log information generated by a radar detector may be generated as audio data. In this way, if the audio is played back by the audio playback software of the transfer destination personal computer or the like, the information generated by the radar detector is included in the audio as information that can be made audible. The operation log information generated by the radar detector contained in the file can be confirmed.

  Further, the predetermined file format is a JPEG format capable of storing position information, and includes an information system (server) that processes a file in the JPEG file format transmitted from the memory card 14 by wireless communication. The location specifying information, which is information for specifying the location at the time of storing this file, is acquired based on the wireless reception state (SSID acquisition status and SSID distribution map) of the wireless LAN module 46, and the acquired It is preferable to provide a function of storing the position specifying information in association with the file and transmitting the information by wireless communication. The radar detector includes a GPS receiver 8 that detects the current position, and the control unit 18 generates position information of the position detected by the GPS receiver 8 as information generated by the radar detector. The information system (server) uses the position information specified based on the position specifying information associated with the file in the JPEG file format and the information detected by the GPS receiver 8 and generated by the radar detector in the JPEG file format. The position information stored in the JPEG file format may be determined based on the position information embedded in the file. In this manner, the position information specified based on the position specifying information (SSID) acquired by the memory card 14 and the information detected by the GPS receiver 8 of the radar detector and generated by the radar detector are JPEG files. Since the position information to be stored in the JPEG file format is determined based on both position information of the position information embedded in the format file, the position information finally embedded in the JPEG file format file It is possible to obtain position information with higher position accuracy. As a method for calculating highly accurate position information from a plurality of position information, for example, a conventionally known method can be used.

  The personal computer according to the present embodiment is an information system that acquires a JPEG file format file transmitted from the memory card 14 to the server via wireless communication from the server and processes the file, and detects the embedded radar detection from the JPEG file. It has a function to take out the operation log information generated by the machine and store it as a separate file. Therefore, the operation log information generated by the radar detector can be recorded in the personal computer as a file different from the JPEG format file. This separate file can also be in a file format unique to the radar detector. For example, it may be a file in a file format conventionally used by this radar detector. In this way, the file can be acquired by wireless communication without changing the program in the information system from the conventional one.

  As information to be embedded in a JPEG file format file, the information includes a transfer destination information of the file, and has a function of reading the transfer destination information and transferring at least one of the file or the separate file to the transfer destination. It is good also as a structure. In this way, information generated by the radar detector can be transferred to a predetermined transfer destination. For example, even when the transfer destination in the transfer device is fixed to a predetermined transfer destination, the file can be transferred to a transfer destination other than the predetermined transfer destination. In the case of this configuration, for example, the control unit 18 of the radar detector may perform a process of embedding information including information on the transfer destination of the file as information to be embedded in the file in the JPEG file format.

  In the present embodiment, a radar detector with a drive recorder function has been described as an example of an electronic device. However, the present invention is not limited to this and can be applied to various electronic devices having an SDHC memory card slot. Further, the present invention can be applied to various electronic devices that correspond to memory card standards other than SDHC and have a function of recording data other than image data.

  For example, FIGS. 8 and 9 are examples in which the present invention is applied to a speed measuring device. This speed measuring device measures the head speed and ball speed of a golf club by the Doppler effect of the emitted microwave, and from these and the set club information ("1W" in the figure indicates the 1st wood) The estimated flying distance and meet rate of the ball are displayed. The measurement result is a memory card inserted in the SDHC memory card slot as a file for each measurement date in CSV format in the order of measurement date, measurement time, head speed, estimated flight distance, ball speed, meet rate, club type. To be recorded. For example, in the example of FIGS. 8 and 9, the data “2011/08/10, 10:00, 48.9,252,68.9,1.41,1W” is the file name “20110810 in the“ DATA ”folder of the SDHC memory card. Is recorded as a new line in the file. In the speed measuring device of FIG. 8, the portion of FIG. 9 is a display unit, and is composed of a color dot matrix liquid crystal display. As described above, when the measured data is added to the CSV file, image data in JPEG format as shown in FIG. 9 is generated, and “2011/08/10, 10:00, 48.9, Embed measurement data such as “252,68.9,1.41,1W” and save it as “201108101000.jpg” in the “DCIM” folder. By doing so, the file with the file name “201108101000.jpg” is wirelessly transferred to the server. When this file transferred to the server is acquired and opened by a personal computer, an image as shown in FIG. 9 is displayed. If the measurement data is extracted from the embedded area of this file, the measurement data “2011/08/10, 10:00, 48.9,252,68.9,1.41,1W” can be extracted.

  The image to be JPEG format image data may be the content displayed on the display unit as shown in FIG. 9, or may be an image including a main body other than the display unit around the display unit as shown in FIG. Good. If the image includes the main body, it is possible to easily determine by which image the data stored by the device is embedded.

  Further, the display on the display unit is not a display on a dot matrix, but a segment type display screen as shown in FIG. 10, and the image data to be generated may be generated as an image imitating this segment.

In this embodiment, the embedded image file is generated by the implant JPEG method, but a method of embedding in the image itself by a technique such as digital watermarking or steganography may be used. In addition, for example, use a publicly known method described in, for example, “Japan Patent Office Standard Technology Collection Electricity 2002 Digital Watermark http://www.jpo.go.jp/shiryou/s_sonota/hyoujun_gijutsu/denshi_sukashi/index.htm” Can do.
