  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. The following description shows an example in which the present invention is applied to a terminal device such as a PC.

[Configuration of terminal device]
FIG. 1 shows a schematic configuration of the terminal device 1. The terminal device 1 includes an input device 2, a storage device 4, an arithmetic device 5, and a display device 6. The input device 2 includes a keyboard and a mouse attached to the terminal device 1, and is used when a user inputs instructions, selections, and the like.

  The storage device 4 stores map data and photograph data. The map data is used in, for example, a general vehicle-mounted navigation device, and includes location information (latitude, longitude, etc.), place name information, road information, and the like regarding a number of geographical points.

  Photo data is image data taken at a geographical point. Specifically, the photographic data is obtained by taking a picture of a local landscape at predetermined intervals while traveling on a certain road. In a preferred example, a photograph of peripheral images taken at predetermined intervals (for example, 5 m) on a specific geographical road is used as photographic data. Therefore, usually, the photographic data taken at adjacent points are similar images. Further, by looking at the photograph data prepared along a certain road in order, it is possible to roughly know the actual landscape change when traveling on that road.

  In the storage device 4, the photographic data is stored in association with positional information, specifically latitude and longitude, at the geographical point where it was photographed. An example of the data structure of the photographic data stored in the storage device 4 is shown in FIG. As shown on the left side of FIG. 5A, each piece of photo data is associated with the file name and the position information of the shooting position. In this example, coordinate information indicating latitude (XXX ??) and longitude (YYY ??) is used as position information.

  The display device 6 differs depending on the type of the terminal device 1, but is generally configured by a liquid crystal panel or the like. The display device 6 displays a photographic map according to the present invention. The photo map is a pseudo map configured by reducing the photo data and arranging the photo data according to the position information. Details thereof will be described later.

  The arithmetic device 5 performs each process of the terminal device 1 by executing various programs stored in the storage device 4. In this embodiment, the arithmetic unit 5 performs a process of creating a photographic map mainly using the above photographic data. The computing device 5 also performs route search based on the user's specification of photographic data or points.

  In the above configuration, the storage device 4 functions as storage means in the present invention, and the arithmetic device 5 functions as display control means, enlarged display means, continuous display means, and route search means in the present invention.

[Photo map]
Next, a photographic map that is a characteristic part of the present invention will be described. A photo map is a map that is a pseudo map by reducing photo data and arranging it according to the shooting location. FIG. 2 schematically shows an example of a photographic map. FIG. 2 shows a normal map 20 and a photographic map 21. The normal map 20 is a map displayed by, for example, a car navigation device, and includes road information, building information, and the like. On the other hand, the photo map 21 is a display in which photo data reduced (hereinafter referred to as “reduced photo data 22”) are displayed side by side. Here, the photograph map 21 has a plurality of reduced photograph data 22 arranged at positions corresponding to the geographical positions. That is, in the photo map 21, a plurality of reduced photo data 22 are displayed in a state in which the relative positional relationship between the shooting points is maintained. In addition, as described above, the photograph data is taken at points at predetermined intervals on the road in principle. Therefore, when the reduced photograph data 22 is arranged according to the relative positional relationship between the photographing points, a photograph is obtained as shown in FIG. The arrangement of the plurality of reduced photograph data 22 on the map 21 forms a pseudo road shape.

  In FIG. 2, for convenience of illustration, each reduced photograph data 22 is schematically shown by a simple rectangle. However, in actuality, each reduced photograph data 22 is image data reduced to a predetermined size, and its shooting location. Contains images. FIG. 3 shows an example of a photo map created using photo data taken along a certain road. In the photo map 21, the adjacent reduced photo data 22 is composed of captured images of adjacent regions, and thus has similar image contents.

  Since the terminal device 1 shown in FIG. 1 stores normal map data and photo data in the storage device 4, the user selects the normal map 20 and the photo map 21 as shown in FIG. It is possible to switch and display according to the above. Further, as illustrated in FIG. 4, the terminal device 1 may display a photographic map superimposed on a normal map. As can be understood from FIG. 4, the arrangement of the reduced photo data 22 constituting the photo map 21 substantially matches the shape of the road in the actual map. In the example of FIG. 4, for convenience of explanation, only some roads are displayed as photographic maps.

[View larger image]
In the photo map of the present embodiment, when the user selects the reduced photo data 22 constituting the photo map, it can be enlarged and displayed. Hereinafter, an enlarged display when the user designates one reduced photo data 22 (also referred to as “single enlarged display”) and an enlarged display when the user designates a plurality of reduced photo data 22 (“continuous enlarged display”). ")."

(Single enlarged display)
First, single enlarged display will be described. As shown on the left side of FIG. 2, when the user operates the input device 2 or the like while the photo map 21 is displayed and selects a certain reduced photo data 22, the terminal device 1 selects the selected reduced photo. The data 22 is enlarged and enlarged photo data 23 is displayed. Thereby, the user can easily enlarge and display the photographic data at a desired point, that is, the photographed image at the point.

  The storage device 4 originally stores photo data of a predetermined size as an image file. If the size of the photo data stored in the storage device 4 is referred to as “original size”, the reduced photo data 22 refers to photo data having a size smaller than the original size. In this case, the reduction rate of the reduced photo data 22 compared to the original size is determined as appropriate according to the scale of the photo map or the size of the area covered by one photo map, and is not necessarily a fixed value. On the other hand, the enlarged photo data 23 refers to photo data enlarged from the size of the reduced photo data 22. Similarly, the enlargement or reduction ratio of the enlarged photo data 23 compared to the original size is appropriately determined according to the area of the area on the display device 6 that displays the enlarged photo data 23, and is not necessarily a fixed value. Therefore, the size of the enlarged photo data 23 is larger than the size of the reduced photo data 22, but does not have to match the original size.

(Continuous enlargement display)
Next, continuous enlargement display will be described. When the user designates a plurality of reduced photograph data 22, the terminal device 1 sequentially enlarges and displays the designated plurality of reduced photograph data 22.

  A first embodiment of continuous enlargement display will be described with reference to FIGS. Now, as indicated by a thick line in FIG. 5B, when the user designates the reduced photograph data A to E in this order using a mouse or the like as the input device 2, the arithmetic unit 5 displays FIG. 5C. As shown in FIG. 5, the enlarged photograph data 23 corresponding to the reduced photograph data A to E is displayed on the display device 6 in the order designated by the user, that is, the order of the photograph data A to E. The display time interval of each enlarged photograph data 23 can be set to a predetermined time such as 1 second. Thereby, the user can view the photos at the shooting point of each photo data in order (such a display method is generally called “slide show”, “slide display”, etc.). That is, the user can see an image similar to what is seen when traveling sequentially through the shooting locations of the reduced photo data A to E, and can roughly know the scenery and state of the section. Instead of setting the display time interval of each enlarged photo data and automatically switching and displaying it, it is also possible to display on the next photo when the user selects the next photo (that is, manually displayed photo) Switching).

  In the above example, since the enlarged photo data A to E are displayed in order, basically, the photo displayed earlier in time is overwritten by the photo displayed later and becomes invisible. On the other hand, as shown in FIG. 5D, in another example, the enlarged photo data A to E may be displayed side by side in the vertical or horizontal order (hereinafter referred to as “parallel display”). .

  Next, the continuous enlarged display process according to the first embodiment will be described with reference to FIG. FIG. 6 is a flowchart of the continuous enlargement display process according to the first embodiment. First, when the user designates a rectangular area to be displayed as a photographic map, the arithmetic device 5 receives the designation (step S11). Next, the arithmetic unit 5 determines coordinates (XXXAA, YYYAA) and (XXXZZ, YYYZZ) that define the rectangular area, reads out the photo data existing in the rectangular area from the storage device 4, and cache memory Copy to etc. Then, each photo data is reduced to a predetermined size to create reduced photo data 22, and a photo map is created by arranging them in a relative positional relationship according to corresponding position information (latitude and longitude), The information is displayed on the display device 6 (step S12).

  Next, when the user selects, for example, a photo selection mode and clicks and selects a plurality of reduced photo data (reduced photo data A to E in the example of FIG. 5) to be displayed, the arithmetic device 5 Receives the information (step S13). As described above, the storage device 4 stores, for each of a plurality of pieces of photo data, the image data (image file) and the position information (coordinate information) of the point where the image data is taken in association with each other. Therefore, if the user designates the reduced photo data A to E in this order, the arithmetic unit 5 uses the reduced photo data as shown in FIG. 5A based on the photo data stored in the storage device 4. The coordinate information of A to E is acquired. Then, the arithmetic unit 5 sets the display order of the respective photo data A to E, enlarges each reduced photo data A to E to a predetermined size, and creates enlarged photo data 23 (step S14). Then, the arithmetic unit 5 executes the slide display as shown in FIG. 5C by sequentially displaying the enlarged photo data in the determined display order (step S15). In this way, the user can display enlarged versions of the reduced photo data designated by the user in the designated order. In addition, the aspect which displays each enlarged photograph data 23 in step S15 is good also as a parallel display like FIG.5 (d).

  Next, a second embodiment of continuous enlargement display will be described with reference to FIGS. Now, as shown in FIG. 7B, it is assumed that the user uses the mouse or the like as the input device 2 to specify the reduced photo data A as the start point and the reduced photo data E as the end point. The arithmetic unit 5 executes a route search with the shooting position of the reduced photo data A as the start point (starting point) and the shooting position of the reduced photo data E as the end point (destination).

  At this time, in this embodiment, the route search is executed with reference to the inter-photograph association data (hereinafter simply referred to as “association data”) attached to each piece of photodata. As shown in FIG. 7A, in this embodiment, association data is attached to each piece of photo data. The association data indicates photograph data at another photographing position adjacent to the photographing position of the photograph data. For example, as shown in FIG. 7A, for the reduced photo data A, there are reduced photo data B and F adjacent thereto, and these are stored as association data. Similarly, for the reduced photo data B, there are reduced photo data A and C adjacent to it, and H and I, and these are stored as association data. The arithmetic unit 5 refers to the association data and searches for a route from the position of the reduced photo data specified as the start point to the position of the reduced photo data specified as the end point. In this example, as shown in FIG. 7B, a search route to the reduced photograph data A to E is obtained by route search.

  After that, the arithmetic unit 5 basically performs the same processing as in the first embodiment. That is, as shown in FIG. 5C, the enlarged photograph data 23 corresponding to the reduced photograph data A to E is obtained in the order along the route obtained by the route search, that is, the order of the photograph data A to E. Displayed on the display device 6. Thereby, the user can slide-display the photos of the shooting points of the respective photo data in the order of the searched routes. It should be noted that in slide display, manual display photo switching may be employed without setting the display time interval of each enlarged photo data. Further, as shown in FIG. 5D, the enlarged photo data may be displayed in parallel.

  Next, continuous enlargement display processing according to the second embodiment will be described with reference to FIG. FIG. 8 is a flowchart of the continuous enlargement display process according to the second embodiment. First, when the user designates a rectangular area to be displayed as a photographic map, the arithmetic unit 5 receives the designation (step S21). Next, the arithmetic unit 5 determines coordinates (XXXAA, YYYAA) and (XXXZZ, YYYZZ) that define the rectangular area, reads out the photo data existing in the rectangular area from the storage device 4, and cache memory Copy to etc. Then, each photo data is reduced to a predetermined size to create reduced photo data 22, and a photo map is created by arranging them in a relative positional relationship according to corresponding position information (latitude and longitude), The information is displayed on the display device 6 (step S22).

  Next, the user selects, for example, the photo selection mode, designates one reduced photo data (reduced photo data A in the example of FIG. 7) as a starting point, and the arithmetic unit 5 receives the designation (step S23). Similarly, the user designates another reduced photo data (reduced photo data E in the example of FIG. 7) as the end point, and the arithmetic unit 5 receives the designation (step S24). Then, as shown in FIG. 7A, the arithmetic device 5 performs a route search from the start point to the end point based on the association data, and obtains routes to the reduced photo data A to E (step S25).

  Next, the arithmetic unit 5 sets the display order of the reduced photo data A to E according to the route obtained by the search, and creates the enlarged photo data 23 by enlarging each reduced photo data A to E to a predetermined size. (Step S26). Then, the arithmetic unit 5 performs slide display as shown in FIG. 5C by displaying each enlarged photograph data in order in the determined display order (step S27). In this way, the user can display an enlarged version of the reduced photo data existing on the route searched based on the start point and the end point designated by the user in the route order in the route. In step S27, the display mode of each enlarged photograph data 23 may be parallel display as shown in FIG.

  Next, a third embodiment of continuous enlargement display will be described with reference to FIGS. Now, as shown in FIG. 9B, the user designates a point X adjacent to the reduced photo data A as the start point and the reduced photo data E as the end point using the mouse or the like as the input device 2. To do. The arithmetic unit 5 performs a route search with the position of the point X as the start point (starting point) and the shooting position of the reduced photograph data E as the end point (destination).

  At this time, in the third embodiment, the route search is executed based on the vehicle travel route information by the road network database. It is assumed that the vehicle travel route information based on the road network database is stored in advance in the storage device 4 as road information. Therefore, in the third embodiment, the association data as in the second embodiment is not attached to the photo data. Further, as shown in FIG. 9A, the vehicle travel route information includes position information (latitude and longitude) of each point (including the point X) on the road network. Therefore, the user can select a point other than the position of the photo data as the start point or the end point. Thus, in this example, as shown in FIG. 9B, a search route to the reduced photograph data A to E is obtained by route search.

  Thereafter, the arithmetic device 5 basically performs the same processing as in the second embodiment. That is, as shown in FIG. 5C, the enlarged photograph data 23 corresponding to the reduced photograph data A to E is obtained in the order along the route obtained by the route search, that is, the order of the photograph data A to E. Displayed on the display device 6. Thereby, the user can slide-display the photos of the shooting points of the respective photo data in the order of the searched routes. It should be noted that in slide display, manual display photo switching may be employed without setting the display time interval of each enlarged photo data. Further, as shown in FIG. 5D, the enlarged photo data may be displayed in parallel.

  Next, continuous enlargement display processing according to the third embodiment will be described with reference to FIG. FIG. 10 is a flowchart of the continuous enlargement display process according to the second embodiment. First, when the user designates a rectangular area to be displayed as a photographic map, the arithmetic device 5 receives the designation (step S31). Next, the arithmetic unit 5 determines the coordinates (XXXAA, YYYAA) and (XXXZZ, YYYZZ) of the two points that define the rectangular area, reads out the photo data existing in the rectangular area from the storage device 2, and cache memory Copy to etc. Then, each photo data is reduced to a predetermined size to create reduced photo data 22, and a photo map is created by arranging them in a relative positional relationship according to corresponding position information (latitude and longitude), The information is displayed on the display device 6 (step S32).

  Next, the user selects, for example, the photo selection mode, designates one point (the point X in the example of FIG. 9) as a starting point, and the arithmetic unit 5 receives the designation (step S33). Similarly, the user designates another reduced photo data (reduced photo data E in the example of FIG. 9) as the end point, and the arithmetic unit 5 receives the designation (step S34). Then, as shown in FIG. 9B, the arithmetic device 5 performs a route search from the start point to the end point based on the vehicle travel route information, and obtains routes to the reduced photo data A to E (step S35). ).

  Next, the arithmetic unit 5 sets the display order of the reduced photo data A to E according to the route obtained by the search, and creates the enlarged photo data 23 by enlarging each reduced photo data A to E to a predetermined size. (Step S36). Then, the arithmetic unit 5 performs slide display as shown in FIG. 5C by displaying each enlarged photograph data in order in the determined display order (step S37). In this way, the user can display an enlarged version of the reduced photo data existing on the route searched based on the start point and the end point designated by the user in the route order in the route. In step S37, the display mode of each enlarged photograph data 23 may be displayed in parallel as shown in FIG.

  In the continuous enlargement display processing according to the first to third embodiments described above, the size of the enlarged photo data is basically the size of the area on the display device on which they are displayed and the size of the enlarged photo data to be displayed. It is determined as appropriate based on the number. Therefore, the size of each enlarged photo data displayed by continuous enlargement display may be different from the size when only one photo data is selected (that is, in the case of single enlargement display).
