Image processing device, information storage device, and image processing method

摘要

An image processing device includes an information acquisition section that acquires a photographing position of a photographed image or a position of an imaging device as coordinate information, a distribution state acquisition section that acquires a distribution state of a plurality of pieces of coordinate information acquired as the coordinate information, and a keyword assignment section that assigns a keyword that corresponds to the acquired distribution state to the photographed image.

主权项

1. An image processing device comprising:
an information acquisition section that acquires a photographing position of a photographed image or a position of an imaging device as coordinate information; a distribution state acquisition section that acquires a distribution state of a plurality of pieces of coordinate information acquired as the coordinate information, wherein the distribution state acquisition section includes a cluster classification section that classifies the coordinate information into a plurality of clusters that include at least a first cluster and a second cluster, and wherein the cluster classification section classifies the first cluster and the second cluster into a reference cluster that serves as a reference and a non-reference cluster that does not serve as a reference; and a keyword assignment section that assigns a keyword that corresponds to the acquired distribution state to the photographed image, wherein the cluster classification section classifies one of the first cluster and the second cluster as the reference cluster based on one of (i) a number of photographed images, (ii) a selection by a user, (iii) a time-series transition history of the coordinate information in a two-dimensional coordinate space that represents a geographical position, (iv) a complexity of a distribution of coordinates in the first cluster indicated by the coordinate information and a complexity of a distribution of coordinates in the second cluster indicated by the coordinate information, and (v) a geographical distance between photographing positions with respect to a threshold value which is set to be larger for the non-reference cluster than for the reference cluster.
