1 is a block diagram showing the configuration of a navigation device according to a first embodiment of the present invention.

Referring to the figure, the navigation device is a CPU 1 which executes software necessary for navigation.
, A memory 2 for storing programs and data, a global positioning system (hereinafter referred to as “GPS”) device 3 for detecting the current position of the vehicle, and communication for controlling input / output data and communicating between the CPU and the outside. An input / output control unit 4, a voice output unit 5 for outputting voice and sound, a display control unit 6 for controlling display of a screen for navigation, and image data for video output are stored. A frame memory 7, a CD-ROM 8 for storing maps and guidance data, a speaker 9 for providing voice guidance, and a display device 10 including a CRT (cathode ray tube) or liquid crystal display.
And a terminal that allows external control of recording and playback (VIS
Camcorder 11 which is a video recording device having a CA, etc.
And a demultiplexer 12 for the video signal.

VISCA is an abbreviation for video system control architecture, which is an interface standard developed for connecting video equipment to a computer. Other standards can be used regardless of VISCA as long as recording on a video tape can be controlled from the outside. The camcorder may be integrated with the navigation device for video recording.

The demultiplexer 12 may be omitted if it is unnecessary. With this navigation device, it is possible to automatically keep a record of the traveling of the vehicle. The navigation device control software recorded in the memory 2 uses a clock function of the navigation device and a vehicle position detection function to set a timing (for example, 3) preset by the driver.
Every 0 minutes, every 20 km of travel, etc.), the movement information of the vehicle is recorded for a set time. Image data such as a map image output from the navigation device via the display device 10 to the driver for guidance and voice output via the speaker 9 are recorded on the camcorder 11 as they are.

Specifically, by the processing shown in the flow chart of FIG. 2, a record of the movement of the vehicle is automatically left in the camcorder 11.

Referring to the figure, when the power is turned on, the device is initialized in step S1.
The initialization is a process of confirming the current position of the vehicle equipped with the navigation device, for example.

In step S2, based on the current position information of the vehicle input from the GPS device 3, the CPU 1 determines, via the input / output control unit 4, the current position of the vehicle among the map data recorded in the CD-ROM 8. Read the included map data. The CPU 1 draws map data and the current position of the vehicle in the frame memory 7 via the display control unit 6. The map data drawn in the frame memory 7 and the current position of the vehicle are displayed on the display device 10.

In step S3, it is determined whether or not a preset timing has come. Here, the preset timing is a timing based on the passage of a predetermined time, the vehicle traveling a predetermined distance, or the like. Other than this, it is possible to set not to record when the position of the vehicle changes by a predetermined distance or less from the previous recording position even at the timing when the predetermined time has elapsed. By making such a setting, the amount of recorded data can be reduced.

If YES in step S3, the same content as that displayed on the display device 10 in step S4 is recorded in the camcorder 11. At the same time, the same voice as the voice output from the speaker 9 is recorded in the camcorder 11.

Recording is performed for a predetermined time. Also, while the recording is being performed, the CPU 1 updates the content displayed on the display device 10 according to the change in the position of the vehicle and outputs the corresponding sound from the speaker 9.

The camcorder is controlled by the input / output control unit 4 and records the information input from the video input terminal and the audio input terminal. However, a person in the vehicle can manually take a picture of the scenery outside the vehicle. . In this case, manual operation of the camcorder may be prioritized over control from the navigation device. In this way, with the passage of time, the map showing the current position of the vehicle and the image such as the scenery captured by the camcorder are recorded on the video tape, so that it is possible to easily record the movement of the vehicle. . That is, specifically, when the camcorder is not manually operated, the image data output to the display device for guidance to the driver and the audio output output from the speaker are recorded as they are. For example, as shown in FIG. 4, after the image data of the display device (the map image and the current position 20 of the vehicle) at time t is recorded for x minutes, as shown in FIG. 5, the image at time t + t1 is x. Recorded for a minute. Further, when voice guidance is being provided at the time of recording these images, the voice guidance is also recorded in the camcorder.

When the camcorder is manually operated between the state shown in FIG. 4 and the state shown in FIG. 5, referring to FIG. 6, the map shown in FIG. Next to the image, an image such as a landscape near the position of (A) shown in (B) is recorded on the video tape, and thereafter, as shown in (C), a map showing the current position of the vehicle thereafter. Image is recorded.

Further, as the information to be recorded, it is possible to record additional information in addition to the content displayed on the display device and the sound output from the speaker.

For example, the time at which the recording is performed can be displayed on the display device only while the image is recorded, or a voice can be uttered such as "x: y minutes is near Nishikujo". This makes it possible to record information suitable for traveling recording in addition to information related to actual navigation, further improving the usability of the device.

Further, in the navigation device of the present embodiment, the camcorder automatically starts recording information at the set timing. At this time, however, in order to prevent the driver from being surprised by a sudden motor sound, the camcorder records the information. Before starting the operation and before ending the recording, it may be possible to pay attention by voice or the like, "Trip recording will start from now" (see the flowchart of FIG. 3). Further, the same effect can be obtained by outputting a predetermined buzzer sound or displaying a caution on the display device without using such a voice.

For example, referring to FIG. 6, before the map image shown in (A) is recorded by the camcorder,
The announcement "Start travel recording" is made from the speaker and recording of the map image is started. At this time, a voice "10 o'clock near Mt. Fuji" is recorded as additional information on the camcorder, and video recording is continued for, for example, 1 minute. Immediately before ending the recording, an announcement "Travel recording will be ended" is output from the speaker.

Next, referring to (B), a passenger of the vehicle manually operates the camcorder to record a landscape image. At this time, if the image is recorded while the connection between the camcorder and the navigation device is kept as it is, the usability is improved. A landscape can be recorded by a person who likes a target for a desired time.

[0038] Referring to (C), at a further predetermined timing, the announcement "Travel recording will be started" is made, and the voice "10:30, near Hakone mountain" is recorded, and one minute Video recording is done for a while. Immediately before the video recording ends, the announcement "Travel recording will be ended" is output.

As is clear from this example, the information recorded in the camcorder is very easy to edit the record after traveling because it maintains the temporal continuity regardless of whether it is from the navigation device or the landscape. Can be done.

FIG. 7 is a block diagram showing the configuration of the navigation device according to the second embodiment of the present invention. Referring to the figure, the difference between this navigation device and the navigation device in the first embodiment is that the duplexer 1
2 is deleted, and the video / audio / control signal sending unit 13 is used instead.
Is provided to record video and audio on the camcorder 11.
The point is that the signal output from the video / audio / control signal transmission unit 13 is recorded.

The video / audio / control signal output unit 13 is an interface such as IEEE 1394 (serial SCSI) which can send out the video / audio data together with the control signal. By using this interface, it is not necessary to store the image to be sent to the camcorder in the frame memory 7, and it is possible to freely create the image on the memory 2 independently. Similarly, the audio data can be recorded in the camcorder 11 without passing through the audio output unit 5. As a result, an image or sound different from the image or sound output to the driver for guidance is displayed on the camcorder 11.
It is possible to record independently.

That is, an advantage of the navigation device in the present embodiment is that it is possible to record, as a travel record, data that has nothing to do with driving guidance. For example CD
-When data such as tourist information is stored in the ROM in addition to map images, the driver should automatically leave it in the camcorder 11 as a travel record even if the driver does not see the data of the tourist information. Is possible. For example, in the specific example shown in FIG. 6, it is possible to automatically record tourist information about Mt. Fuji on a video tape of a camcorder when passing by Mt. Fuji (state shown in FIG. 6A).

In the first and second embodiments, the camcorder 11 is maintained in the navigation device. However, a signal such as a map image from the conventional navigation device is input to the external camcorder at a predetermined timing. By sending the image data, it is possible to create a travel recording device that leaves travel records and the like. By continuing the existing navigation device and the existing camcorder in such a device, the same effect as that of the above-described embodiment can be obtained. This makes it possible to provide an inexpensive traveling recording device.

Although a camcorder is used as the recording medium in the embodiment, any storage medium can be used as long as the map image can be recorded.

Further, the map image may be recorded by a key input from the user. Furthermore, although the camcorder is supposed to be able to take pictures of landscapes, it is also possible to record only map images.
