FIG. 5 is functional block diagram illustrating a
functional configuration of the index generating unit 51.
The index generating unit 51 functionally includes an image
feature vector extracting unit 61 and a cluster generating
unit 62. The cluster generating unit 62 generates
a tree structure of a representative vector, which is an
index of a cluster, and stores information on the index
into a tree structure representative vector storing unit 72.
The cluster vector storing unit 71 stores information on
the image feature vector 22 belonging to the cluster (cluster
represented by the representative vector), which is a
leaf of the tree structure. Specifically, the cluster vector
storing unit 71 and the tree structure representative vector
storing unit 72 are formed of the storage unit 12.
