Abstract

An information processing device which displays on a map a plurality of images classified by hierarchical clustering and associated with positional information includes a deciding unit configured to decide clusters satisfying a predetermined condition from among clusters created by the hierarchical clustering as the same group and a display control unit configured to perform control such that the clusters belonging to the group are displayed on a reduced scale map based on positional information of the respective clusters belonging to the group.

Claims

1. An information processing device which displays on a map a plurality of images classified by hierarchical clustering and associated with positional information, the information processing device comprising:

deciding means for deciding clusters satisfying a predetermined condition from among clusters created by the hierarchical clustering as the same group; and

display control means for performing control such that the clusters belonging to the group are displayed on a reduced scale map based on positional information of the respective clusters belonging to the group.

2. The information processing device according to claim 1,

wherein the display control means performs control such that a representative image selected from at least one image included in each cluster is displayed at a position based on the positional information of each cluster belonging to the group on the reduced scale map based on the positional information of the respective clusters belonging to the group.

3. The information processing device according to claim 1,

wherein the positional information of each cluster is information based on positional information of the image included in each cluster.

4. The information processing device according to claim 1,

wherein the predetermined condition is a condition regarding the range of density of child clusters included in each cluster, and

the deciding means calculates the density of child clusters included in each cluster, and decides clusters, in which the calculated density falls within a predetermined range, as the same group.

5. The information processing device according to claim 1, further comprising:

clustering means for clustering the images associated with the positional information to a binary tree structure in accordance with distances based on the positional information.

6. The information processing device according to claim 1, further comprising:

input means for inputting an instruction to select one of the clusters being displayed,

wherein the display control means performs control such that, on a reduced scale map based on positional information of respective clusters belonging to a lower layer group in a hierarchy lower than that of the group to which the cluster selected in accordance with the instruction by the input means belongs, the clusters belonging to the lower layer group are displayed.

7. The information processing device according to claim 6,

wherein the input means instructs to display clusters belonging to an upper layer group in a hierarchy higher than that of the group to which the clusters being displayed belong, and

the display control means performs control on the basis of the instruction by the input means such that the clusters belonging to the upper layer group are displayed on a reduced scale map based on positional information of the respective clusters belonging to the upper layer group.

8. The information processing device according to claim 6,

wherein the input means is a remote controller.

9. An information processing method for an information processing device which displays on a map a plurality of images classified by hierarchical clustering and associated with positional information, the method comprising the steps of:

deciding clusters satisfying a predetermined condition from among clusters created by the hierarchical clustering as the same group; and

performing control such that the clusters belonging to the group are displayed on a reduced scale map based on positional information of the respective clusters belonging to the group.

10. A program which causes a computer to execute a process of an information processing device, which displays on a map a plurality of images classified by hierarchical clustering and associated with positional information, the process comprising the steps of:

deciding clusters satisfying a predetermined condition from among clusters created by the hierarchical clustering as the same group; and

performing control such that the clusters belonging to the group are displayed on a reduced scale map based on positional information of the respective clusters belonging to the group.

11. An information processing device which displays on a map a plurality of images classified by hierarchical clustering and associated with positional information, the information processing device comprising:

a deciding unit configured to decide clusters satisfying a predetermined condition from among clusters created by the hierarchical clustering as the same group; and

a display control unit configured to perform control such that the clusters belonging to the group are displayed on a reduced scale map based on positional information of the respective clusters belonging to the group.
