A wide angle is desirable.

  Next, the operation of the above configuration will be described with reference to FIGS. FIG. 2 is a flowchart illustrating the process performed by the control unit 5 of the navigation device 2. Here, it is assumed that the cellular phone 3 is attached to the adapter 4 in a power-on state, and the control unit 5 stores the image data and audio data transferred from the cellular phone 3 in the external storage device 22. To do.

  In the navigation device 2, while the vehicle is traveling, the control unit 5 calculates GPS signals, vehicle speed signals, angular velocity signals, and acceleration signals to periodically acquire the vehicle position and reads map data from the recording medium 21. Thus, the intersection position where the vehicle is predicted to pass is identified, the accident frequent occurrence zone where the vehicle is predicted to pass is identified from the accident frequent occurrence zone information received by the VICS receiver 6 from the VICS center 20, and the user operates The user registration point where the vehicle is predicted to pass among the user registration points registered in advance by operating the switch group 14 is identified.

  Now, whenever it acquires a vehicle position (step S1), the control part 5 determines the positional relationship between the acquired vehicle position and the intersection position where accidents are expected to pass, accident-prone areas, and user registration points. (Steps S2-4).

  When the control unit 5 determines that the vehicle position approaches the intersection position and the distance from the vehicle position to the intersection position is within a predetermined distance ("YES" in step S2), the control unit 5 performs the shooting start command and collection A sound start command is output from the input / output interface unit 19 to the mobile phone 3 to start shooting by the camera 27 of the mobile phone 3 and to start sound collection by the microphone 28 (step S5). The voice data collected by the microphone 28 is input from the mobile phone 3 by the input / output interface unit 19, and the storage of the input image data and voice data in the external storage device 22 is started (recording and recording are started).

  Next, when the control unit 5 determines that the vehicle has passed the intersection position without any problems (without encountering an accident) and the distance from the intersection position to the vehicle position is equal to or greater than a predetermined distance (in step S6, “ YES ”), a shooting end command and a sound collection end command are output from the input / output interface unit 19 to the mobile phone 3, and the shooting by the camera 27 of the mobile phone 3 is ended and the sound collection by the microphone 28 is ended (step S7). Then, the storage of the image data and the sound data in the external storage device 22 is ended (recording and recording are ended). And the control part 5 erase | eliminates the image data and audio | voice data which were memorize | stored in the external storage device 22 because the vehicle position approached the intersection position (step S8), and returns to above-described step S1.

  Similarly, when the control unit 5 determines that the vehicle position approaches the accident-prone area and the distance from the vehicle position to the accident-prone area is within a predetermined distance (“YES” in step S3), photographing starts. The command and the sound collection start command are output from the input / output interface unit 19 to the mobile phone 3 to start shooting by the camera 27 of the mobile phone 3 and to start collecting sound by the microphone 28 (step S9). The image data and sound data collected by the microphone 28 are input from the mobile phone 3 by the input / output interface unit 19, and storage of the input image data and sound data in the external storage device 22 is started.

  Next, when the control unit 5 determines that the vehicle has passed through the accident-prone area without any problem and the distance from the accident-prone area to the vehicle position is equal to or greater than a predetermined distance ("YES" in step S10), shooting is performed. An end command and a sound collection end command are output from the input / output interface unit 19 to the mobile phone 3, the photographing by the camera 27 of the mobile phone 3 is terminated and the sound collection by the microphone 28 is terminated (step S 11), and image data and audio are recorded. The storage of data in the external storage device 22 is terminated. And the control part 5 erase | eliminates the image data and audio | voice data which were memorize | stored in the external storage device 22 because the vehicle position approached the accident frequent occurrence zone (step S12), and returns to above-described step S1.

  Further, when the control unit 5 determines that the vehicle position approaches the user registration point and the distance from the vehicle position to the user registration point is within a predetermined distance (“YES” in step S4), the imaging start command and A sound collection start command is output from the input / output interface unit 19 to the mobile phone 3 to start shooting by the camera 27 of the mobile phone 3 and to start sound collection by the microphone 28 (step S13). The voice data collected by the microphone 28 is input from the mobile phone 3 by the input / output interface unit 19, and the storage of the input image data and voice data in the external storage device 22 is started.

  Next, when the control unit 5 determines that the vehicle has passed through the user registration point without any problem and the distance from the user registration point to the vehicle position is equal to or greater than a predetermined distance (“YES” in step S14), the photographing is performed. An end command and a sound collection end command are output from the input / output interface unit 19 to the mobile phone 3, the photographing by the camera 27 of the mobile phone 3 is terminated and the sound collection by the microphone 28 is terminated (step S 15), and image data and audio are recorded. The storage of data in the external storage device 22 is terminated. And the control part 5 erase | eliminates the image data and audio | voice data which were memorize | stored in the external storage device 22 because the vehicle position approached the user registration point (step S16), and returns to above-described step S1.

  By the way, although the case where recording and recording were performed simultaneously was demonstrated above, only recording may be performed and recording may be performed as needed. Further, when recording or recording, in order to notify the occupant (especially the driver) that recording or recording is in progress, as shown in FIG. It may be displayed. FIG. 3 shows a display screen when recording and recording are started when the vehicle position approaches within a predetermined distance to the intersection of “XX town”. For example, a display guidance “recording and recording” is displayed. Is displayed in the upper right part of the screen. Further, at the same time that such display guidance is displayed, for example, a voice guidance “currently recording or recording” may be output from the speaker 23.

  Further, the case where the image data and the sound data are stored in the external storage device 22 separate from the navigation device 2 has been described above. However, the image data and the sound data are stored in the storage device 15 built in the navigation device 2. It may be memorized. In addition, if the external storage device 22 is installed in a portion having a higher impact resistance than the navigation device 2 or is ruggedly protected, the image data is protected from the viewpoint of protecting data when an accident occurs. In addition, it is desirable to store the audio data in the external storage device 22 separate from the navigation device 2 instead of storing it in the storage device 15 built in the navigation device 2.

  Note that the predetermined distance that is a criterion for starting recording and recording and the predetermined distance that is a criterion for ending recording and recording may be set uniformly by the user in advance. The control unit 5 may automatically set the vehicle position every time the vehicle position approaches an intersection position, an accident-prone area, or a user registration point based on the vehicle speed or the like. For example, if the vehicle speed is relatively high, it is desirable to start recording or recording in a state where the predetermined distance from the vehicle position to the intersection position, accident-prone area, or user registration point is relatively long, while the vehicle speed is relatively If it is late, it is desirable to start recording or recording with a relatively short predetermined distance from the vehicle position to the intersection position, accident-prone area, or user registration point. Further, the item for determining the positional relationship with the vehicle position may be any one of an intersection position, an accident-prone area, and a user registration point.

  As described above, according to the present embodiment, in the in-vehicle image recording system 1, when the vehicle position approaches within a predetermined distance to an intersection position, an accident-prone area, or a user registration point, photographing by the camera 27 of the mobile phone 3 is performed. Since it is configured to start and store the captured image data in the external storage device 22, many accidents occur on the road based on the intersection position where the accident may occur or past statistics. It is possible to start shooting inside and outside the vehicle at the timing when the vehicle approaches within a predetermined distance to the accident-prone area determined to be and the user registration point where the user felt dangerous in the past and registered, Images useful for accident inspection can be recorded.

  Further, when the vehicle position approaches within a predetermined distance to the intersection position, accident-prone area, or user registration point, sound collection by the microphone 28 of the mobile phone 3 is started, and the collected sound data is also stored in the external storage device 22. Therefore, not only images useful for accident inspection but also sounds useful for accident inspection can be recorded.

  Further, when the vehicle position moves away from the intersection position, accident-prone area, or user registration point by a predetermined distance or more, the photographing by the camera 27 of the mobile phone 3 and the sound collection by the microphone 28 are terminated, and the photographed image data and sound are collected. Since the storage of the audio data in the external storage device 22 is terminated and the stored image data and audio data are erased, the vehicle has moved away from the intersection position, accident-prone area, and user registration point by a predetermined distance or more. The photographing inside and outside the vehicle and the sound collection inside and outside the vehicle can be terminated at the timing, and the storage area for storing the image data and the sound data can be used repeatedly and effectively. Furthermore, since the display device 13 is configured to display that recording or recording is in progress, the user can be made aware that recording or recording is in progress.

The present invention is not limited to the above-described embodiment, and can be modified or expanded as follows.
The imaging unit is not limited to the configuration using the camera 27 of the mobile phone 3, and may be a configuration using another camera such as a camera mounted for another purpose such as driving assistance or a dedicated camera. . The configuration using not only the microphone 28 of the mobile phone 3 as the sound collecting means but also a configuration using another microphone such as a microphone or a dedicated microphone mounted for another purpose such as destination setting by voice input, for example. It may be. At that time, a larger amount of information can be obtained by using a camera having a wide field of view and a microphone having a wide angle sound collection range (omnidirectional characteristics).
A configuration may be employed in which image data and audio data are transferred from the mobile phone 3 to the navigation device 2 by wireless communication such as Bluetooth (registered trademark) or wireless LAN.
