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 when the engine is started and turned off immediately, the operation log data imaging function is not executed and the process ends. 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 contents of the operation log in the file is generated. As a characteristic content of the operation log, an image including a departure date and time, a departure place, an arrival date and time, and an arrival place is generated. For example, as shown in FIG. 7, the title is "operation log", the departure date is "2010-01/10 10:30:25", the departure place is "Meito-ku, Nagoya-shi, Aichi", and the arrival date is "2010-01/10 11: 25:13”, arrival place “Toyota-cho, Toyota-shi, Aichi”, etc., and the fonts stored in the non-volatile memory are expanded and displayed. Below the title, a horizontal dividing line is drawn.

The date and time of departure shall be the date and time recorded in the first line of the operation log file, and the place of departure shall be searched in order from the first line of the operation log file and the latitude and longitude data acquired from the line where the current position data is recorded first. The corresponding place name is specified and displayed based on the map data of the database 19. This is because the GPS receiver 8 may not be able to acquire position information 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 displayed by specifying the corresponding place name of the latitude/longitude data acquired from the last line of the operation log file based on the map data of the database 19.

In subsequent S130, the image data displayed in S120 on the display unit 5 is encoded into a JPEG image file, and the operation log file of the current travel section is further 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 the 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 to and stored in the “DCIM” folder.

In subsequent S150, the operation data file of this time is moved to the "image generated" folder, and this processing is ended.
In this way, the image files stored in the "DCIM" folder are wirelessly transferred to the disk of the server of the file storage service preset by the personal computer.

In this way, the list of transferred data can be displayed as thumbnails by entering the server address in the browser of the personal computer connected to the Internet, entering the ID and password, and accessing this server. can do. From the thumbnail display of the displayed list, select the files to download to your computer by checking the check box and downloading.

In this way, when displayed as thumbnails, for example, as shown in FIG. 7, since the departure date/time, the departure place/the arrival date/time, and the arrival place are displayed in the thumbnail image, data necessary for oneself is displayed. You can check the data by looking at the thumbnail of the image and select it.
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 thumbnails of the files in the "My Pictures" folder with the filer of your own PC (for example, Windows (registered trademark) Explorer, Mac is a standard filer called Finder) You can see if the log is embedded inside.

A program for extracting the embedded file from the implant JPEG file is stored in its own personal computer. When this program is executed, the JPEG file selection screen is displayed, and the file embedded in the selected JPEG file is extracted and stored in the folder (directory) selected as a new file. Be seen.

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, it is a radar detector that can be connected to the memory card 14 that includes the flash memory 44 and that has a function of transmitting a file in the JPEG file format among files stored in the flash memory 44 by a wireless communication. The memory card reader 13 for connecting the card 14 and the control unit 18 for controlling the flash memory 44 of the memory card 14 to store the JPEG file format file are provided. The control unit 18 generates the radar detector. It has a function of embedding information to be stored in a JPEG file format file. Therefore, 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 wirelessly communicates the file with the wireless LAN module. It will be transmitted from 46. Therefore, even a radar detector having no 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 electrical characteristics and structure, and the memory card reader 13 is for connecting a memory card of the SDHC memory card standard, and the control unit 18 Generates an image file as a JPEG file format file, generates operation log information that is not defined in the JPEG image file file format standard as information generated by the radar detector, and embeds it in the JPEG file format file. , And is stored in the flash memory 44.

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

Note that the memory card 14 targets only files in the “DCIM” folder for transmission by wireless communication, and may have a function of deleting files already transmitted by wireless communication from the storage unit. The control unit 18 may be configured to store a file in the JPEG file format in the “DCIM” folder and store a backup file for 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 and stored in the “DCIM” folder. 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 controller 48 of the memory card 14. If you try to use it, you can refer to the backup file in the "backup" folder and use it for processing. For example, the content of the previous operation log can be displayed when the engine is turned on next time. For example, if the engine on this time is the engine on after the operation shown in FIG. 7, the image in FIG. 7, which is the latest image stored in the “backup” folder, is displayed on the display unit 5 for 20 seconds. Let By doing so, the acquisition status of the previous 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 kinds of processing. In addition, for example, even if the recording medium storing the file acquired by wireless communication from the memory card 14 is lost or the file is deleted from the recording medium, the information system including the memory card reader ( The information generated by the radar detector can be re-acquired from the “backup” folder of the memory card 14 by connecting the memory card 14 to, for example, a personal computer.

The backup file may be any file that includes information generated by the radar detector, and this file may be one file or a plurality of files. Further, this file may be added to an existing file, or a new file may be created.

Further, it is preferable that the above-mentioned embedding is performed when a file in the JPEG file format is stored in the “DCIM” folder, and whether or not to store a backup file in the “backup” folder is determined. That is, it is not necessary to create backup files corresponding to all JPEG file format files, and for example, it is advisable to create a file that backs up only the necessary information generated by the radar detector. For example, when the radar detector detects from the acceleration sensor 25 an acceleration in the front-rear direction of 0.3 G or more, which is an acceleration corresponding to the impact at the time of a collision, the screen of the display unit 5 is the same as the screen of FIG. 7. "Caution for sudden deceleration" is displayed in the title part of the, and a screen displaying the date and time and the place where the sudden deceleration is detected is displayed below that, and a file in the 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 file to be backed up is created in the “backup” folder, while the copy to the “backup” folder in S140 of FIG. 6 is not performed. Good.

The JPEG file format file of the present embodiment has a file format identification area for identifying whether or not the file is the JPEG file format file, and the function of embedding the information generated by the radar detector in the JPEG file format file is An implant JPEG format for storing information (operation log information) generated by the radar detector is embedded in an area other than the file format identification area. Further, the memory card 14 having the extension ".JPG" is influenced by the operation log information generated by the radar detector in order to identify whether the file is a JPEG file format file or not by referring to the file format identification area. Instead, the JPEG file is determined to be in the JPEG file format, and the JPEG file is transmitted by wireless communication. Therefore, even a radar detector having no wireless communication function can transfer the information generated by the radar detector by wireless communication.

The JPEG file format is a file format that stores information that can be visualized, and the control unit 18 embeds log information generated by a radar detector in a file in the JPEG file format and visualizes information generated by the radar detector. It is also configured to generate it 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 the image of this JPEG file with the image viewer software such as the transfer destination personal computer, the information generated by the radar detector is included in the image as visible information. Then, you can check the information generated by the radar detector contained in the file. For example, it is possible to easily confirm which file contains the necessary information by displaying the image as a thumbnail or displaying a slide show on the transfer destination personal computer or the like.

Further, in the present embodiment, the information generated by the radar detector is generated as character string information as the information that can be visualized, but it may be generated as a two-dimensional code. For example, it is preferable that the character string displayed as shown in FIG. 8 and the content of the character string are displayed in the two-dimensional code and embedded in the JPEG file. By doing so, for example, in an information system such as a personal computer, it is possible to display the character string information as the information that can be visualized, and the information generated by the radar detector contained in the file can be confirmed by the character string. Moreover, it is possible to easily read the two-dimensional code with a mobile device or the like and transfer at least a part of the information generated by the radar detector to the mobile device or the like.

In addition, in the present embodiment, the display unit 5 is provided, and the control unit 18 is configured to generate at least a part of the information displayed on the display unit 5 as visible information. Therefore, at least a part of the information displayed on the display unit 5 of the radar detector is displayed as visible information only by opening the file with a viewer of an information system such as a personal computer. Further, for example, at least a part of the information displayed on the display unit 5 of the radar detector can be displayed as visible information on 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 for various devices to know when the recorded information is included. It becomes possible to specify.

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

The information generated by the electronic device is information that changes over time, the predetermined file format is a moving image file format, and the visible information is information that changes over time. May be synchronized with the passage of time of the moving image file and generated as the information that can be visualized. For example, the video data in the embodiments shown in FIGS. 1 to 7 may be configured to display the items to be recorded in the operation log file. For example, the longitudinal acceleration may be displayed in the image. By doing so, it is possible to grasp the information contained in the file, which is generated by the electronic device at that time, only by reproducing the moving image file in the information system.

Further, the video data may store audible information. For example, the radar detector may further include a microphone, and the control unit 18 may capture the sound from the microphone and store the sound in the video data. The control unit 18 can embed the operation log information generated by the radar detector in a file of a video data file format, and read the operation log information generated by the radar detector by voice synthesis to make it audible in the image data. It is advisable to adopt a configuration in which it is also generated as various information. For example, when the acceleration exceeds a predetermined value, the acceleration is read aloud by voice synthesis and generated as audible information in the video data. By doing so, for example, it is possible to reproduce the sound about the acceleration in the video data generated by the radar detector as the information that can be made audible by the information system such as the personal computer.

Further, the operation log information may be embedded in a file of a voice file format as a file format for storing audible information, and the log information generated by the radar detector may be generated as voice data. In this way, if the sound is played back with sound playback software such as the transfer destination PC, the information generated by the radar detector is included in the sound as audible information, and only the sound is heard. Then, you can check the operation log information generated by the radar detector included in the file.

Further, the predetermined file format is a JPEG format capable of storing position information, and an information system (server) for processing a file of the JPEG file format transmitted from the memory card 14 by wireless communication is provided. The position specifying information, which is the information for specifying the position 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 information is acquired. It is preferable to have a function of storing the position specifying information in association with the file and transmitting the information by wireless communication. The radar detector includes the GPS receiver 8 for detecting the current position, and the control unit 18 generates position information of the position detected by the GPS receiver 8 as the information generated by the radar detector. The information system (server) uses the JPEG file format as the position information specified based on the position specifying information associated with the JPEG file format file and the information detected by the GPS receiver 8 and generated by the radar detector. The position information to be stored in the JPEG file format may be determined based on the position information embedded in the file. By doing so, the JPEG file is used as the position information specified based on the position specifying information (SSID) acquired by the memory card 14 and the information generated by the radar detector detected by the GPS receiver 8 of the radar detector. Since the position information to be stored in the JPEG file format is determined based on both the position information embedded in the format file, the position information finally embedded in the JPEG file format is It is possible to obtain position information with higher position accuracy than that. As a method of 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 by wireless communication from the server and processes the 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 a file format specific to the radar detector. For example, it may be a file of 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.

The information of the transfer destination of the file is included as the information to be embedded in the file of the JPEG file format, and the function of reading the information of the transfer destination and transferring at least one of the file and the another file to the transfer destination is provided. It may be configured. By doing so, the 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 adopting this configuration, for example, the control unit 18 of the radar detector may perform the process of embedding the information of the transfer destination of the file as the information to be embedded in the file of the JPEG file format.

In the present embodiment, the radar detector having the drive recorder function is used as an example of the electronic device, but 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 corresponding to memory card standards other than SDHC and having 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 instrument measures the head speed and the ball speed of the golf club by the Doppler effect of the emitted microwaves, and from the information of the club set as these ("1W" in the figure indicates the 1st wood) The estimated flight distance of the ball and the meat rate are displayed. The memory card installed in the SDHC memory card slot is a file of each measurement date in CSV format with the text of measurement date, measurement time, head speed, estimated flight distance, ball speed, meet rate, and club type in order. Recorded in. 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. Will be recorded as a new line in the file. In the speed measuring device of FIG. 8, the portion of FIG. 9 is the display portion and is composed of a color dot matrix liquid crystal display. As described above, when the measured data is added to the CSV file, the image data in the JPEG format as shown in FIG. 9 is generated, and the image data “2011/08/10, 10:00, 48.9, Embed the measurement data such as "252,68.9,1.41,1W" and save it in the "DCIM" folder with the file name "201108101000.jpg". 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 by a personal computer and opened, an image as shown in FIG. 9 is displayed. Moreover, when 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 used as the JPEG image data may be the content displayed on the display unit as shown in FIG. 9, or may be the image including the 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 what device the data saved is embedded.

Further, the display on the display unit may be a segment type display screen as shown in FIG. 10 instead of the dot matrix display, and the image data to be generated may be generated as an image simulating this segment.

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