Abstract

An information processing apparatus includes: an input unit that inputs an image as an input image, the image being recorded in correlation with information related to ground point of photography; an image selection unit that selects, as selected images, a plurality of images from among the input images input by the input section; a region extraction unit that extracts a map region on the basis of a number of the selected images included in a predetermined region upon the map, the predetermined region including the ground points of the selected images selected by the image selection unit; and a display unit that displays the map region extracted by the region extraction unit with photographic ground point signs, the photographic ground point manifesting the ground point of the selected image.

Claims

1. An information processing apparatus, comprising:

an input unit that inputs an image as an input image, the image being recorded in correlation with information related to ground point of photography;

an image selection unit that selects, as selected images, a plurality of images from among the input images input by the input section;

a region extraction unit that extracts a map region on the basis of a number of the selected images included in a predetermined region upon the map, the predetermined region including the ground points of the selected images selected by the image selection unit; and

a display unit that displays the map region extracted by the region extraction unit with photographic ground point signs, the photographic ground point manifesting the ground point of the selected image.

2. An information processing apparatus according to claim 1, wherein

the region extraction unit sets split regions as the predetermined regions, and extracts a plurality of the map regions from the map on the basis of the numbers of the photographic ground point signs within the split regions, the split region having been created by splitting the map at predetermined intervals.

3. An information processing apparatus according to claim 2, further comprising:

a number of images display unit that, for each of the split regions, displays the number of the photographic ground point signs displayed within the split region.

4. An information processing apparatus according to claim 1, wherein:

the region extraction unit sets a predetermined size of a region as the predetermined region, and extracts the region from the map as the map regions, the number of the selected images in the region satisfying some predetermined condition.

5. An information processing apparatus according to claim 1, wherein:

the map regions that are displayed by the display unit can be set by a user as desired.

6. An information processing apparatus according to claim 1, wherein:

sizes of the map regions that are extracted from the map by the region extraction unit can be set by a user as desired.

7. An information processing apparatus according to claim 1, wherein:

the region extraction unit extracts, as the map regions, regions for which the number of the selected images is greater than or equal to a number that has been set by a user.

8. An information processing apparatus according to claim 1, wherein:

the region extraction unit extracts the plurality of map regions from the map while also taking into account a priority order assigned to each of the selected images within the predetermined regions upon the map.

9. An information processing apparatus according to claim 1, further comprising:

a change unit that, on the basis of a command from the user, changes at least one of a scale of the map region displayed by the display unit and a display range of the map region, on the basis of a command from a user.

10. An information processing apparatus according to claim 1, further comprising:

a map data acquisition unit that specifies a country in which the selected images selected by the image selection unit have been photographed, and acquires map data from a server in the specified country.

11. An information processing apparatus according to claim 1, wherein:

the region extraction unit performs extraction so that the plurality of map regions do not overlap one another.

12. An information processing apparatus according to claim 4, wherein:

the region extraction unit extracts the region from the map, as the map regions, the numbers of the selected images in the region being a greatest.

13. An information processing apparatus according to claim 2, wherein:

the region extraction unit changes a size of the split regions according to level of a scale of the map being displayed.

14. An information processing apparatus according to claim 1, wherein

the region extraction unit sets split regions as the predetermined regions, and extracts the map region from the map on the basis of the numbers of the photographic ground point signs within the split regions, the split region having been created by splitting the map at predetermined intervals.

15. An information processing apparatus according to claim 14, further comprising:

a number of images display unit that, for each of the split regions, displays the number of the photographic ground point signs displayed within the split region.

16. A computer readable program product including an information processing program that can be executed by the computer, the information processing program comprising:

an input process of inputting an input image as an input image, the image being recorded in correlation with information related to ground point of photography;

an image selection process of selecting, as selected images, a plurality of images from among the input images;

a region extraction process of extracting a plurality of map regions on the basis of a number of the selected images included in predetermined regions upon the map, the predetermined region including the ground points of the selected images selected by the image selection process; and

a display process of displaying the plurality of map regions that have been extracted by the region extraction process with the photographic ground point signs.
