FIG. 18 (a) shows shooting information of a photographer 1 at 9-12 o'clock, and FIG. FIG. 18 (c) shows shooting information at 9-12 o'clock for a certain photographer 2 and FIG. 18 (d) shows shooting information at 13-17 o'clock for a certain photographer 2. The shooting information is shown.
For a predetermined range on the map, an icon (F) of a different color is displayed depending on the photographer at the shooting point of each photo. When the icon (F) is clicked, a photo (G) at the shooting point is displayed. In addition, an icon (H) indicating a shooting direction is attached to the photograph (G).
Here, for a number of photographs included in a predetermined range on the map, the shooting direction and the shooting elevation angle are aggregated as parameters, and the shooting direction frequency distribution (I) and the shooting elevation frequency distribution (J) are set to the direction or elevation angle. You may display with the circle | round | yen shown with a corresponding radius. As a result, the tendency of taking pictures in the specific area can be grasped and used for sightseeing reference.
The frequency distributions (I) and (J) may also be color-coded by the photographer. Further, depending on the direction, it may be distinguished by shading or hue.

Similarly, for a plurality of photos located in a predetermined range on the map, the shooting times may be aggregated as a parameter, and the frequency distribution of the shooting time zone may be displayed with a 24-hour analog clock hand or the like. . This also makes it possible to grasp the tendency of the time zone in which a photograph is taken in a specific area, which can be used for sightseeing reference.

19 and 20 are maps with display of a photographer's movement route, FIG. 20 (a) is a photographer's shooting information at 9-12 o'clock, and FIG. 20 (b) is a photographer's 12 Shooting information at -15 o'clock, FIG. 20C shows shooting information of a certain photographer 2 at 15-217 o'clock.
For a plurality of photographs located in a predetermined range on the map, the moving route of the same photographer may be displayed with a line segment (K) connecting the photographing points (F). This movement locus (F) may also be color-coded by the photographer. If a large number of photographers are aggregated and analyzed, the movement tendency in a specific area can be grasped and used for sightseeing reference.
In addition, by selecting a plurality of photographs by the same photographer, it is possible to calculate the travel time from the difference between the photographing times and display the estimated time required for sightseeing.

  Such information on movement can also be used for a photo album creation service including information on maps and shooting directions. The album may be an online album on the Internet or a print. Further, when a photo is registered, the subject name candidates and the like may be presented to provide additional information. In that case, in general map data, small shops and tourist spots are treated uniformly regardless of the scale, but with this system, tourist spots and famous landmarks are presented as candidates. It is preferable.

According to these, it is possible to easily estimate the time required for sightseeing and dynamically create a sightseeing model course. For example, if you specify the area around Shijo from 9:00 am to 4:00 pm, the photographer who finished the activity within that time will be given priority to search and display photos and travel history, and if you specify the starting point, the radius It is possible to search and display the movement trajectory of a photographer who has started moving from within 200 m and who has finished the activity within the specified time.

In addition, when a photograph is retrieved using a display terminal (3) having a large display screen such as a PC, the URL to the photograph of the search result or the page of the photograph group is displayed as a QR code, and the QR code is displayed on a small portable terminal such as a mobile phone. By photographing the code, it is possible to obtain information on search result pages, so that it is easy to access these pages on the go.
In addition, when searching based on the shooting direction in a search using line-of-sight information, it is expected that there are many photographs taken in a direction close to the shooting direction specified by the user, especially in the case of famous sightseeing spots. The Therefore, the search area is automatically set based on the range of the map displayed on the screen of a PC, etc., and the photos included in it are searched for those close to the direction specified by the user. Also good. At this time, even if the user does not explicitly specify the elevation angle, for example, when the user performs a similar search using a photo with gaze information as a key, the elevation angle information of the photo used as the key is automatically extracted, Set it as a search parameter. According to this, it is possible to search for a photo close to the user's intention while searching using the line-of-sight information while reducing the number of parameters specified by the user and simplifying the interface.

The present invention may be provided as a program that causes the photographing terminal (1), the server (2), and the display terminal (3) to function as the above-described electronic map photo display system. The program may be provided by being stored in a computer storage medium such as a CD.
