The database is categorized into levels 1 to 8, and as the level number increases, more detailed searches are possible.
This level can be selected by the user while looking at the search status and the like, and can be selected by the search method setting means 7.

FIG. 6 is a flowchart showing an example of a search method for searching for video / audio data already stored in the recording medium 4 and reproducing the data in association with map information. In the flowchart of FIG. 6, when a place name to be searched is input from the search information input unit 15 (step S1), it is first determined whether or not data of the place name exists in the database. If there are no levels, the levels are dropped in order, at least until they are present, and the level is selected. This level corresponds to the place name stored together with the location data when the video / audio data is stored in the recording medium 4. When the data of the place name is input from the search information input section 15, the data is compared with the image / audio data having the position information in the recording medium 4 via the search means 5 (steps S2, S3, S4). . If they match, the recording medium 4
Is read from the recording medium 4 and sent to the image reproducing unit 9 and the audio reproducing unit 13 (step S5). On the other hand, if they do not match, the nearest place name is searched, and the video / audio data corresponding to the nearest place name is read from the recording medium 4 and transmitted to the image reproducing unit 9 and the audio reproducing unit 13. Each is sent (steps S6 and S7), and the data is output.

As described above, in the apparatus according to the present embodiment, when recording at least one type of recorded information (video / audio data) such as a moving image, a still image, or audio, the GPS Receives position information including longitude, latitude, and altitude from a satellite, records the position information (location data) on a recording medium in synchronization with video / audio data, and uses the data for navigation (map information / location name information database). Since video and audio data related to the position information corresponding to the specific position on the map are displayed, for example, moving images, still images, or recorded audio taken while driving in a car are associated with location data and displayed on the screen. Can simultaneously display map information and video / audio information. This makes it easy to grasp the state at the time of photographing, the situation on the route, and the like, and to easily grasp the entire image. Furthermore, if there is a still image, it is possible to easily know when and where the image was taken together with the time data already in practical use.

In addition, audio data in the navigation is output through an audio device (for example, an in-vehicle audio device), and when audio data from the navigation is output, audio data from the navigation is prioritized. , The navigation information can be transmitted reliably.
