FIG. 3 shows a data recording area of the travel record disk 2. The data recording area of the travel record disk 2 is composed of first to fourth areas.

In the first area, material data including title character data, still image data, moving image data, audio data, map data, etc. corresponding to a certain travel version is recorded.
The material data is already recorded in the first area when the travel record disc 2 is sold. The title character data of the material data is character string data to be superimposed and displayed on a still image or the like during editing. The still image data of the material data is, for example, still image data of a famous tourist destination of a travel destination. The moving image data of the material data is, for example, moving image data of a famous event at a tourist destination of a travel destination. The audio data of the material data is, for example, music data used for BGM during still image reproduction.
The map data of the material data is the data of a map to the extent that the travel route at the travel destination can be confirmed.

As shown in FIG. 4, the title character data, still image data, moving image data, audio data, map data, etc. included in the material data have positional information (for example, the center of the area) indicating an area of a certain size. Attribute information including latitude, longitude, range radius), date and time information, and keyword information is added. However, not all position information, date and time information, and keyword information are added as attribute information to all material data. For example, keyword information (Yufuin, Oita, Onsen) is added as attribute information to the title character data td2 indicating the character string “Yufuin”. Further, for example, the still image data p1 which is the data of a landscape photograph of Mount Aso includes position information (latitude 32 ° 52′N, longitude 131 ° 04′E, effective range 2).
0 km) and keyword information (Mt. Aso, Kumamoto, volcano) are added as attribute information.

User data including still image data, AV data, travel route history data, etc. is recorded in the second area of the travel record disk 2. As shown in FIG. 5, the still image data and the AV data included in the user data have position information indicating the shooting location, date and time information indicating the shooting date and time, and attributes including keyword information related to the shooting location and the subject. Of the information, at least date and time information is added.

Regarding the position information which is the attribute information of the user data, if the digital video camera 3 or the digital still camera 4 has a function of recognizing its own location such as a GPS (Global Positioning System) signal receiving function. , Can be added to user data as attribute information. Regarding the keyword information that is the attribute information of the user data, a character string input by the user may be added as keyword information of the image data or the AV data in the digital video camera 3 or the digital still camera 4, or a disc recorder. In 1, the character string input by the user may be added as keyword information.

In the third area of the travel record disk 2, edit data indicating the reproduction order of user data and material data edited by the edit processing described later is recorded.

In the fourth area of the travel journal disk 2, information about the recording position, data size, etc. of each material data, each user data, edit data, etc. on the travel journal disk 2 described above is described. Management data is recorded.

Next, the editing process of the disc recorder 1 will be described with reference to the flowchart of FIG. As a premise that the editing process is started, it is assumed that the disc recorder 1 has the travel record disc 2 mounted therein, and the user data has already been recorded in the second area of the travel record disc 2. To do.

In step S1, the CPU 11 executes a grouping process for associating the user data recorded in the second area of the travel record disc 2 with the material data recorded in the first area.

The grouping process will be described with reference to the flowchart of FIG. In step S11,
The CPU 11 determines whether or not the travel route history data exists in the user data recorded in the second area of the travel record disc 2. If it is determined that the travel route history data exists, the process proceeds to step S12.

In step S12, the CPU 11 selects, from the still image data and the AV data as the user data recorded in the second area of the travel record disk 2,
The attribute information to which the position information is not added is extracted. In step S13, the CPU 11 compares the date and time information of the still image data and the AV data to which the position information is not added with the movement route history data, and thereby the position information of the still image data and the AV data to which the position information is not added. Is estimated and recorded as attribute information in the second area. The CPU 11 manages for which user data this position information is estimated, and the estimated position information is recorded in a memory such as the RAM 13 instead of the second storage area. May be.

By the processes of steps S12 and S13, position information and date / time information are added as attribute information to all still image data and AV data included in the user data. However, when it is determined in step S11 that the travel route history data does not exist in the user data, the processes of steps S12 and S13 are skipped.

In step S14, the CPU 11 groups user data having position information of a shooting location as attribute information and material data having wide-area position information as attribute information based on the position information. In particular,
When the wide-area position information of the material data includes the position information of the shooting location of the user data, the material data and the user data are classified into the same group.

In step S15, the CPU 11 determines, based on the keyword information, the user data and the material data which are not classified into any group in the processing of step S14 and which have the keyword information as the attribute information. Classify into each group. Specifically, when the keyword information of unclassified user data (or material data) matches the keyword information of user data and material data belonging to a certain group, the unclassified user data (or material data) is changed to Classify into this group.

Further, the CPU 11 excludes the material data which has not been classified into any group by the processing up to step S15 from the subsequent processing targets, and the user data which has not been classified into any group based on the date and time information. For example, grouping is performed in chronological order.

In step S16, the CPU 11 classifies the material data classified into any of the groups into the same group based on the date / time information of the user data classified into the same group or the movement route history data. Set the rough date and time information to the extent that the relationship between the data and the time can be determined.

By the grouping process described above, for example, the material data shown in FIG. 4 is recorded in the first area, and the user data shown in FIG. 5 is recorded in the second area. For example, in the processing of steps S12 and S13, the position information of the still image data up2 of the user data is estimated.

In the processing of step S14, based on the position information, the still image data up1 of the user data and the still image data p1 of the material data are in the same group (hereinafter referred to as group A).
Called)). Further, the still image data up2 of the user data and the still image data p2 of the material data are classified into the same group (hereinafter referred to as group B).

In the processing of step S15, the keyword information "hot spring" of the title character data td2 of the material data
Coincides with the keyword information “hot spring” of the still image data p2 of the material data classified into the group B, the title character data td2 of the material data is classified into the group B. Further, since the keyword information “Asoyama” of the moving image data v1 of the material data matches the keyword information “Asoyama” of the still image data p1 of the material data classified into the group A (further, it is classified into the group A. Since it matches the keyword information “Mt. Aso” of the still image data up1 of the user data), the moving image v1 of the material data is group A
are categorized.

Returning to FIG. In step S2, the CPU
Reference numeral 11 determines the reproduction order of each group based on the material data belonging to each group and the date and time information of the user data. Further, the CPU 11 arranges the material data and user data belonging to the group in the group based on the date and time information, and according to the order, sets the reproduction timing of the still image or the moving image on the reproduction time axis and edits the data. Produces
The data is recorded in the third area of the travel record disc 2. In addition,
The edited data includes images showing the moving route on the map and BGM.
It should be generated including the information of the voice data used as. This is the end of the description of the editing process.

FIG. 8 shows an example of video and audio reproduced according to the edit data recorded in the third area of the travel record disk 2 by the above-mentioned edit processing. For the display time of one still image, for example, BGM
The playback time of all the videos is subtracted from the playback time of the song to be determined, and the remaining time is divided by the number of still images to make the decision, or it is displayed in response to a predetermined operation from the user. It may be possible to switch the displayed still image to the next still image or moving image.

The grouping process in step S1 of the editing process can be applied to the retrieval of each material data and each user data recorded on the travel record disk 2. That is, even if data that does not directly match the attribute information as the search condition, but the attribute information of other data belonging to the same group matches the search condition, the data that does not directly match can be searched.

In the third area of the travel record disc 2, a plurality of edit data can be recorded in addition to the edit data generated by the editing process. For example, by allowing the user to change the edit data generated by the edit process,
The changed edited data may be recorded. Further, for example, the travel record disc 2 is sold in a state in which edited data indicating a reproduction order of only material data, such as sequentially reproducing images according to a travel model plan, which is useful when making a travel plan, is recorded. You may do it.

Next, FIG. 9 shows the structure of a digital video camera in which an image editing system including the disk recorder 1, the digital video camera 3, the digital still camera 4 and the car navigation device 5 shown in FIG. 1 is integrated. An example is shown.
